Ingredients
Method
- Prep the basics. Preheat your oven to 375°F (190°C). Grease a 9x13-inch baking dish. If your chicken isn’t cooked yet, season with salt and pepper and pan-sear or bake until done, then chop or shred.
- Par-cook the broccoli. Steam or blanch broccoli florets for 2–3 minutes until bright green and just tender. Drain well and pat dry to avoid watering down the sauce.
- Start the sauce. In a large skillet over medium heat, melt the butter. Add garlic and cook for 30 seconds until fragrant. Whisk in cream cheese until smooth and melty.
- Build the cream base. Pour in heavy cream and chicken broth. Whisk until the mixture is smooth and gently bubbling. Stir in onion powder, smoked paprika, mustard powder, and optional Dijon. Season with salt and pepper.
- Add the cheese. Stir in 1.5 cups of the shredded cheese and the Parmesan until fully melted and silky. The sauce should be thick enough to coat a spoon. Adjust seasoning.
- Assemble the bake. Spread the chicken in an even layer in the baking dish. Scatter the broccoli over the top. Pour the cheese sauce evenly across everything, nudging with a spatula to help it settle.
- Top and bake. Sprinkle the remaining 1/2 cup shredded cheese over the surface. Add bacon or pork rind crumbs if using. Bake for 18–22 minutes, until bubbling at the edges and golden on top.
- Rest and serve. Let it sit for 5–10 minutes so the sauce thickens. Scoop into bowls and enjoy hot.

Keeping It Fresh
- Fridge: Store leftovers in an airtight container for up to 4 days. Reheat gently in the microwave or oven at 325°F until warmed through.
- Freezer: Cool completely, then freeze in freezer-safe containers for up to 2 months.
Thaw in the fridge overnight and reheat covered in the oven so it doesn’t dry out.
- Prevent sogginess: Pat broccoli very dry before assembling. Excess moisture is the main reason casseroles turn watery.
- Meal prep tip: Assemble ahead, cover tightly, and refrigerate up to 24 hours. Add 5–10 minutes to the bake time if starting cold.
Health Benefits
- Keto-friendly macros: This dish is high in fat and protein, with low net carbs, which supports ketosis and steady energy.
- Broccoli power: Broccoli is rich in fiber, vitamin C, vitamin K, and antioxidants that support immune health and digestion.
- Protein for satiety: Chicken provides complete protein, helping with muscle maintenance and keeping you full longer.
- Calcium and minerals: Cheese and cream contribute calcium and phosphorus, supporting bone health.
Common Mistakes to Avoid
- Using raw broccoli. If you skip the quick steam or blanch, the broccoli can stay too firm and release water as it bakes, thinning your sauce.
- Not drying vegetables. Water clinging to broccoli dilutes the sauce.
Drain and pat dry with paper towels.
- Overcooking the sauce. Boiling can cause separation. Keep it at a gentle simmer and whisk until smooth.
- Adding all the cheese at once. Melt most into the sauce and reserve some for topping to avoid a greasy or clumpy texture.
- Under-seasoning. Taste the sauce. Cheese is salty, but the cream base still needs seasoning to shine.
Alternatives
- Protein swaps: Use rotisserie chicken for speed, leftover turkey, or cooked ground chicken.
For a richer option, try diced chicken thighs.
- Veggie variations: Mix in cauliflower florets, zucchini slices (well-salted and patted dry), or spinach. Keep net carbs in mind.
- Dairy tweaks: Swap cheddar with gruyere, Monterey Jack, or pepper jack for a kick. Add a little goat cheese for tang.
- Crunchy topping: Mix crushed pork rinds with Parmesan and a touch of melted butter for a keto “breadcrumb” finish.
- Spice it up: Add red pepper flakes, chipotle powder, or a dash of hot sauce to the sauce.
- Lighter sauce: Replace some heavy cream with unsweetened almond milk plus a pinch of xanthan gum to thicken.
FAQ
How many carbs are in this recipe?
Exact carbs depend on your ingredients, but a typical serving lands around 5–7g net carbs when using broccoli, heavy cream, and standard cheeses.
Check labels and measure portions for accuracy.
Can I use frozen broccoli?
Yes, but thaw and drain it thoroughly first. Squeeze out excess moisture with a clean towel to prevent a watery bake.
Do I have to cook the chicken first?
Pre-cooked chicken works best for texture and timing. If using raw chicken, dice it small, season, and pan-cook before assembling to avoid undercooked pieces.
Can I make this without cream cheese?
You can.
Increase heavy cream slightly and add 1/4 teaspoon xanthan gum to thicken, whisking well. The flavor will be a touch less tangy and rich.
What cheese melts best for this?
A blend works best. Sharp cheddar adds flavor, while mozzarella adds stretch.
Gruyere or Monterey Jack melt beautifully and stay smooth.
How do I keep the sauce from breaking?
Keep the heat moderate, whisk constantly, and add cheese gradually. Avoid boiling once the dairy is in the pan.
Is this good for meal prep?
Absolutely. It stores well, reheats evenly, and stays creamy.
Portion into containers for quick lunches or dinners.
What can I serve with it?
Keep it simple with a leafy green salad, roasted asparagus, or sautéed mushrooms. For non-keto eaters, add rice or crusty bread on the side.
