I love a cozy casserole that comes together fast and feeds my family without fuss. This chicken broccoli dish layers tender chicken cubes and bright florets in a rich, cheesy cream sauce, then goes into the oven until the top is golden and bubbly.

I share two sauce paths so you can choose what fits your pantry: a classic condensed soup mix or a no-canned-soup blend of cream cheese, sour cream, and broth. Both give great flavor and a velvety texture.

My stovetop-to-oven workflow is simple: sear chicken with garlic, blanch the broccoli until crisp-tender, stir the sauce and cheese with the ingredients, assemble in a white baking dish, and bake for about 30 minutes. Look for bubbling edges and a lightly browned top.

Serve straight from the dish and garnish with chopped parsley or chives for a warm weeknight dinner that balances protein and low carb swaps like cauliflower if you need them.

Cozy, cheesy, and low-carb: why I love this creamy chicken broccoli casserole

I love how the sauce hugs tender chicken and crisp-tender broccoli florets in every bite. The melted cheese bubbles into a smooth finish and creates a golden top that pulls apart in strings.

The dish comes together in under an hour and can be assembled a day ahead, then baked when you’re ready. It skips rice or pasta yet stays filling, so it works well for a relaxed family dinner or a keto-friendly weeknight meal.

  • The broccoli stays bright and tender-crisp, adding fresh texture to the savory cream and cheese.
  • It reheats well, making leftovers perfect for next-day lunches.
  • Choose canned soup or a cream-cheese-based sauce to match pantry and dietary needs.

Exact ingredients for my Low-Carb Creamy Chicken & Broccoli Bake

Here’s the exact ingredient list I use to get consistent flavor and texture every time.

Protein and produce

I use 1 lb boneless, skinless chicken breasts cut into 1-inch cubes for even cooking and juicy bites. For the veg, plan on about 14 oz broccoli crowns, cut into broccoli florets and blanched until bright and crisp-tender; drain well.

Creamy sauce base

Canned-soup path: 10.5 oz condensed cream of chicken with herbs (undiluted), 1/4 cup half & half, 2 tbsp melted butter, and 1 tbsp sherry cooking wine. No-soup path: 8 oz cream cheese, 1/3 cup sour cream, 1 cup chicken broth, 1/2 cup white cooking wine or a few tbsp lemon juice; add 6.5 oz sliced mushrooms, 1 tbsp dried minced onion, and 1/2 tsp tarragon if using.

Cheese lineup & pantry boosts

I top with 1 cup freshly grated Parmesan; you can blend in shredded mozzarella or sharp cheddar for stretch or bite. Also have 2 tbsp extra virgin olive oil, 2 cloves minced garlic, 1 tsp sea salt, and 1/2 tsp black pepper on hand. Garnish with a teaspoon or two of chopped parsley or chives and serve in a white casserole dish for a clean presentation.

Step-by-step: how I cook it from stovetop to oven

I start on the stove to build flavor, then finish the dish in the oven for a bubbly, golden top. The method is simple and predictable, so timing feels reliable every time.

Prep and preheat

I preheat to 375°F and butter a medium casserole dish. For the florets, I cut evenly and blanch them until bright green, then plunge them into an ice bath and drain very well.

Sear the chicken and garlic

In a hot skillet I add oil, then chicken and minced garlic. I cook, stirring, for 6–8 minutes until opaque. If extra juices collect, I drain so the sauce won’t dilute.

Stir the sauce and fold in broccoli

For the canned-soup route I stir together condensed soup, half & half, melted butter, and sherry. I fold in chicken, broccoli, half the Parmesan, salt, and pepper.

For the no-soup path I whisk softened cream cheese with sour cream and broth until smooth, then fold in chicken, broccoli, and mushrooms; season to taste.

Assemble and bake

I transfer the mixture to the greased dish, smooth the surface, and sprinkle the remaining cheese on top. Bake about 30 minutes at 375°F (or 20–25 minutes at 350°F for the no-soup version) until edges bubble and the top turns lightly golden.

I let it rest a few minutes, then finish with chopped parsley or chives before serving.

Step Action Time
Blanch Boil florets, ice bath, drain 2–3 minutes
Sear Cook chicken with garlic 6–8 minutes
Bake Assemble, top with cheese, bake until bubbly 20–30 minutes

Low-carb swaps and variations to fit your taste

I often tweak the base and add-ins so the dish fits keto nights, family meals, or quick weeknights. Small changes keep texture and flavor fresh while staying mindful of carbs.

No canned-soup option

I make a from-scratch sauce with 8 oz cream cheese, 1/3 cup sour cream, 1 cup broth, and grated Parmesan. This keeps the chicken broccoli casserole rich without the canned base.

Gluten-free and pantry shortcuts

When I want a canned shortcut that’s gluten-free, I reach for Pacific Foods Organic Cream of Chicken. For speed, shredded rotisserie chicken folds in perfectly.

  • Boost umami with sautéed mushrooms and a sprinkle of parmesan.
  • Add cooked bacon or fold in riced cauliflower to mimic rice while keeping carbs low.
  • Swap frozen broccoli or small cauliflower florets, or use thin zucchini half-moons for variety.
  • Try cheddar on top for sharper bite or mix cheddar and mozzarella for extra melt.
Swap Result Best for
Riced cauliflower Rice-like texture, ~2g net carbs/cup keto nights
Rotisserie chicken Faster prep, tender shredded meat weeknights
Frozen broccoli Convenient, keep slightly undercooked pantry-friendly meals

Make-ahead, fridge, freezer, and reheat instructions

Plan ahead and this casserole becomes a lifesaver for busy evenings and packed lunches. I give simple steps so you can assemble now and bake later, or freeze for another week.

Assemble ahead and bake later

I assemble the dish 1–2 days ahead, cover tightly, and keep it in the fridge. When baking from cold, add 10–15 extra minutes in the oven so the center reaches heat through.

If you need exact minutes, expect about 40–50 minutes total when baking straight from the fridge. Grease the pan well to help the edges release after chilling.

Storing leftovers safely in the fridge

Cool the casserole quickly, then transfer portions to airtight containers. Leftovers keep 3–4 days in the fridge and reheat well for lunches or quick dinners.

Freezing, thawing, and reheating

Cool completely, wrap the cooled dish in plastic and foil, and freeze up to 2–3 months. Thaw overnight in the fridge, then reheat at 350°F until hot and the sauce bubbles again.

Microwave single portions with a few drops of water and a loose cover to keep the sauce from drying. Label packages with date and reheating information for easy rotation.

Stage Storage Duration Reheat cue
Assembled, uncooked Refrigerator 1–2 days Add 10–15 minutes; edges bubble
Cooked, refrigerated Airtight container 3–4 days Hot center; sauce re-fluid
Cooked, frozen Wrapped in plastic+foil 2–3 months Thaw overnight; bake at 350°F

Timing, tools, and technique tips for the perfect bake

Small habits in prep and heat control remove guesswork from the baking step. I keep each task short and focused so the dish finishes with even texture and bright flavor.

Knife cuts, pan heat, and not overcooking the broccoli

I cut chicken into even, bite-size pieces so they sear quickly and finish in minutes. This helps avoid large pieces that stay underdone while the rest cooks.

I use medium heat and a splash of oil with a pat of butter. Cook the chicken about 6–8 minutes until no pink remains. Add garlic once the meat starts to brown so it scents the pan without burning.

For the florets, steam or blanch until crisp-tender and shock them in ice water. Drain and press out excess moisture so the sauce stays thick and the casserole does not turn soggy.

Covered vs. uncovered baking for browning on top

Covering the dish helps even warming and prevents the edges from drying. I uncover for the last 10 minutes to let the top brown and toast lightly.

  • Grate cheese fresh so it melts smoothly across the top.
  • Spread the mixture to the edges to avoid cold spots in the center.
  • Watch for bubbling edges and a faint golden blush as your best timing cues, rather than relying only on minutes.
  • Taste the sauce before baking and adjust salt and pepper to lock in flavor.
Technique Purpose Typical cue
Even cuts Faster, uniform cooking Pieces ~1-inch; cook 6–8 minutes
Medium pan heat Brown without burning garlic Butter melts; chicken browns
Covered then uncovered Even heat, then browning Cover until hot through; uncover last 10 minutes

Nutrition highlights and carb-smart notes

It helps to see protein, fat, and fiber broken down so a meal fits my goals. Below I give clear context for portioning and carb control when you make this chicken broccoli casserole.

Protein, fat, fiber, and net carbs per serving

Similar recipes range from about 335 calories per 197g serving with ~7g carbs, 24g protein, 22g fat, and 1g fiber to roughly 475 calories with 14g carbs, 39g protein, 29g fat, and 3g fiber.

  • I aim for a protein-forward plate — the chicken supplies most of the protein per portion.
  • Broccoli adds fiber and micronutrients while keeping carbs modest — about 3g net carbs per cup of florets.
  • The cheese and cream boost fat for satiety, which helps in a low carb or keto plan.

How broccoli, cheese, and cream support a carb-smart dinner

Parmesan packs flavor and calcium without extra carbs, so you can use less sauce and keep totals lower. I recommend weighing portions and adjusting cheese or sour cream to hit your target calories and macros.

Profile Calories Carbs
Lean version ~335 ~7g
Richer version ~475 ~14g
Broccoli (1 cup) ~55 ~3g net

For precise information, calculate with your exact ingredients and portions. Small swaps change carbs and calories more than you might expect, so I weigh or measure when I want tight control.

What to serve with chicken broccoli casserole

A few quick additions turn this dish from oven-to-table into a full, crowd-pleasing spread. I aim for sides that balance the rich sauce and add color, crunch, or extra fiber for the family.

Low-carb sides: salad, zoodles, and cauliflower rice

Light salads dressed in a bright vinaigrette cut through the richness and add fresh texture.

Zoodles or spaghetti squash make a fiber-friendly base that soaks up sauce without many carbs.

  • Serve cauliflower rice to catch the creamy juices while keeping carbs low.
  • Toss zoodles in olive oil and garlic for a quick, bright side.
  • Garlic-sautéed green beans or asparagus add color and simple flavor.

Family-friendly add-ons for non-keto eaters

When I have picky eaters or kids at the table, I offer easy options so everyone is happy.

  • Buttered rice, penne, or roasted potatoes for those who want more starch.
  • A simple tomato‑cucumber salad for fresh contrast and color.
  • Warm low-carb bread or almond‑flour biscuits to make the dinner feel cozy.
Side type Best for Notes
Salad Lightness Vinaigrette cuts sauce richness
Cauliflower rice / zoodles Low-carb family meals Adds fiber without extra carbs
Rice / pasta / potatoes Non-keto eaters Simple, crowd-pleasing starch options

Keep sides simple — this casserole shines on its own, so pick one or two additions that suit your dinner and the tastes of your family.

Pull a hot, golden dish from the oven tonight with just a few easy steps. I preheat to 375°F, grease the dish, and sear the chicken with garlic for 6–8 minutes. I blanch and drain the broccoli florets well, then stir the sauce, assemble, and top with Parmesan.

If you’re short on prep I use rotisserie chicken or frozen broccoli to save time. Assemble up to 1–2 days in advance and store in the fridge; add 10–15 minutes when baking from cold. I season with salt, pepper, and a teaspoon of garlic, watch for bubbling edges, then rest and garnish with chopped parsley before serving.

Keep a print of the recipe for quick reference. I love how this keto-friendly chicken broccoli casserole cuts carbs without skimping on flavor.

FAQ

Can I use frozen broccoli florets instead of fresh?

Yes — I often use frozen florets to save time. Thaw and drain them well or briefly steam/blanch to remove excess water so the sauce doesn’t get runny. Lightly pat with paper towels before mixing into the casserole.

What cut of chicken works best for this casserole?

I prefer boneless skinless chicken breasts or thighs. Thighs stay juicier; breasts are leaner. Rotisserie chicken is a great shortcut and adds flavor while cutting prep time.

Do I have to use cream cheese or can I use a canned soup alternative?

I use both options depending on pantry stock. Cream cheese with a splash of broth or heavy cream makes a thicker, lower-carb sauce. Canned cream-of-chicken soup works too — choose a low-carb brand like Pacific Foods if you need gluten-free or want a lighter prep.

How can I make this recipe keto-friendly?

Focus on full-fat dairy (heavy cream, cream cheese, cheddar, Parmesan) and add keto-friendly mix-ins like bacon, mushrooms, or cauliflower florets. Skip any flour-based thickeners and keep portion sizes moderate to hit your macros.

What oven temperature and baking time do you recommend?

I usually bake at 375°F for about 20–25 minutes until the top is bubbly and golden. If the broccoli was fully cooked before assembling, check earlier to avoid overcooking. For a cold-from-fridge dish, add 10–15 minutes to the bake time.

Should I cover the dish while baking?

I start covered if the casserole is very saucy to prevent drying, then uncover for the last 8–10 minutes to brown the cheese. Leaving it uncovered from the start works when the filling is thicker and you want a crisp top.

How far in advance can I assemble this and bake later?

You can assemble up to 24 hours ahead and keep it covered in the fridge. Let it sit at room temperature 20–30 minutes before baking and add a few extra minutes to the bake time if chilled.

Can I freeze the casserole, and what’s the best way to reheat?

Yes. Freeze the assembled (but unbaked) casserole in a freezer-safe dish for up to 3 months. Thaw overnight in the fridge, then bake at 375°F until heated through. For leftovers, reheat single portions in the oven at 350°F or in a microwave until warm.

How do I keep the broccoli from getting mushy?

I blanch or steam broccoli just until bright green and slightly tender, then shock in ice water. That stops cooking and preserves texture. Also avoid overbaking: the goal is to heat through and melt cheese without turning florets to mush.

Can I swap cheeses, and which ones give the best flavor?

Absolutely. I like a mix of sharp cheddar for meltiness, Parmesan for savory umami, and mozzarella for stretch. You can use one or any combo based on taste — just stick with full-fat cheeses for the richest, low-carb result.

Do you add extra seasonings or wine to the sauce?

I keep it simple: garlic, salt, black pepper, and a pinch of nutmeg or smoked paprika if I want depth. A splash of dry white wine or sherry lifts the sauce; cook it briefly to burn off the alcohol before adding cream or cheese.

What low-carb sides pair well with this dish?

My go-to sides are a crisp green salad, zoodles tossed in olive oil, or cauliflower rice. For families with picky eaters, roasted carrots or a simple buttered cauliflower mash work well for non-keto diners.

How many servings and calories should I expect per dish?

Serving size varies by portion. Typically a 9×13 dish serves 6–8. Calories depend on ingredients — using full-fat dairy and extra cheese raises them. For a lighter version, use chicken breast, reduced-fat dairy alternatives, and smaller cheese quantities.

Any tips for reducing carbs while keeping flavor?

Replace any starchy thickeners with cream cheese or grated Parmesan to thicken the sauce. Add umami boosters like Worcestershire, Dijon mustard, or cooked mushrooms for depth without extra carbs. Keep portions controlled and bulk the casserole with broccoli or cauliflower florets for fiber.
