Ingredients
Method
- Preheat the oven. Set to 375°F (190°C). Grease a 9x13-inch baking dish or similar casserole pan.
- Cook the chicken (if not using pre-cooked). Season chicken with salt, pepper, and a pinch of paprika. Heat oil in a skillet over medium heat. Cook 5–7 minutes per side until done. Rest, then cube or shred. You’ll need about 4 cups of cooked chicken.
- Prep the broccoli. Steam fresh florets for 3–4 minutes until crisp-tender. If using frozen, thaw and pat dry. Avoid overcooking—broccoli will finish in the oven.
- Make the sauce base. In a saucepan over medium-low heat, melt butter. Add minced garlic and cook 30 seconds until fragrant.
- Add the dairy. Whisk in cream cheese until smooth and melty. Pour in heavy cream and chicken broth. Keep whisking to create a silky sauce.
- Season the sauce. Stir in onion powder, smoked paprika, Dijon mustard, salt, and pepper. Taste and adjust seasoning. The sauce should be slightly salty to flavor the chicken and broccoli.
- Add the cheese. Remove from heat and whisk in 1.5 cups of shredded cheddar until melted. Reserve the remaining 1/2 cup for topping.
- Assemble the bake. Add the cooked chicken and broccoli to the baking dish. Pour the cheese sauce over the top and gently toss or spread to coat everything evenly.
- Top and bake. Sprinkle the remaining cheddar over the casserole. Add bacon crumbles if using. Bake for 18–22 minutes, until bubbling around the edges.
- Broil for color (optional). Switch to broil for 1–2 minutes to brown the top. Watch closely so it doesn’t burn.
- Rest and serve. Let the bake sit for 5 minutes to set. Garnish with chopped parsley or chives. Serve warm.

- Flexible and Budget-Friendly: Use leftover chicken, frozen broccoli, or pantry spices to keep costs down.
- Meal-Prep Friendly: Holds up well in the fridge, making it perfect for plan-ahead lunches.
Common Mistakes to Avoid
- Watery Casserole: Don’t skip patting dry thawed broccoli. Excess moisture dilutes the sauce.
- Overcooked Chicken: If starting raw, cook just until done.
Dry chicken will stay dry even in sauce.
- Breaking the Sauce: Keep heat moderate when melting cream cheese and cheddar. High heat can cause separation.
- Under-Seasoning: Taste the sauce before assembling. It should be boldly seasoned to carry through the whole dish.
- Skipping the Rest: Letting the bake sit for a few minutes helps the sauce thicken and cling to each bite.
Alternatives
- Veggie Swaps: Use cauliflower florets, green beans, or a mix of broccoli and zucchini (lightly sautéed to reduce moisture).
- Protein Swaps: Turkey, shredded rotisserie chicken, or cooked ground chicken all work.
For a pescatarian twist, try cooked, flaked salmon and swap smoked paprika for lemon zest.
- Cheese Variations: Mix cheddar with Monterey Jack, mozzarella for extra melt, or pepper jack for heat.
- Add-Ins: Crisp bacon, chopped jalapeños, diced sautéed mushrooms, or a spoonful of ranch seasoning for a different profile.
- Dairy-Light Option: Replace some heavy cream with unsweetened almond milk and add a pinch of xanthan gum to thicken. Note: flavor will be lighter.
- Spice it Up: Add red pepper flakes, chipotle powder, or hot sauce to the sauce for a kick.
FAQ
Is this recipe strictly keto?
Yes. It’s built around low-carb ingredients like chicken, broccoli, cream, and cheddar.
It fits most keto macros, but exact carbs depend on brands and portion size.
Can I make this ahead?
Yes. Assemble the casserole up to the point of baking, cover, and refrigerate for up to 24 hours. Add 5–8 extra minutes to the bake time if it goes into the oven cold.
How can I thicken the sauce if it feels too loose?
Simmer the sauce for a minute or two longer to reduce slightly, or whisk in a small pinch of xanthan gum.
It will tighten quickly, so use sparingly.
What if I don’t have cream cheese?
You can substitute mascarpone or a mix of heavy cream and a handful of extra cheddar. The sauce will be a bit thinner but still rich.
Can I use pre-shredded cheese?
Yes, but freshly shredded cheddar melts smoother. If using bagged cheese with anti-caking agents, whisk a bit longer to get a silky sauce.
What sides go well with this?
It’s hearty on its own, but a simple side salad, roasted asparagus, or sautéed spinach pairs well without adding many carbs.
How do I avoid a greasy top?
Use a good balance of cheese to liquid and don’t overbake.
Letting the casserole rest helps the fats reincorporate into the sauce.
Can I make it in a skillet?
Absolutely. If your oven-safe skillet is large enough, assemble and bake right in it. It makes for even easier cleanup.
