Ingredients
Method
- Prep the oven and dish: Preheat to 375°F (190°C). Lightly grease a 9x13-inch baking dish with cooking spray or butter.
- Season the chicken: In a bowl, toss chicken pieces with olive oil, garlic powder, onion powder, smoked paprika, salt, and pepper. Set aside.
- Par-cook the broccoli: For fresh broccoli, steam or microwave for 2–3 minutes until bright green and just tender. For frozen, thaw and pat dry. This step helps avoid a watery bake.
- Make the creamy sauce: In a medium bowl, whisk together cream cheese, sour cream, heavy cream, and chicken broth until smooth. Stir in Dijon, Italian seasoning, 1 cup cheddar, mozzarella, and Parmesan. Season with a pinch of salt and pepper.
- Assemble: Spread broccoli in the baking dish. Scatter seasoned chicken over the top. Pour the cheese sauce evenly over everything, then gently toss to coat. Smooth into an even layer.
- Top with cheese: Sprinkle the remaining 3/4 cup cheddar over the surface.
- Bake: Place on the middle rack and bake for 25–30 minutes, until the chicken is cooked through (165°F/74°C in the thickest pieces) and the edges are bubbling.
- Broil for color (optional): Switch to broil for 1–2 minutes to get a golden, bubbly top. Watch closely to avoid burning.
- Rest and serve: Let the bake rest 5–10 minutes to thicken. Garnish with parsley and serve hot.

How to Store
- Refrigerator: Cool completely, then store in an airtight container for up to 4 days.
- Freezer: Freeze portions in freezer-safe containers for up to 2 months. Thaw overnight in the fridge before reheating.
- Reheat: Microwave individual servings in 45–60 second bursts, stirring once, until hot. Or reheat in a 325°F (165°C) oven, covered, for 12–15 minutes.
- Avoid drying out: If reheating in the oven, add a splash of broth or cream and cover with foil.
Benefits of This Recipe
- Keto-compatible: Low in carbs, high in fat and protein, and very filling.
- Nutrient-dense: Broccoli provides fiber, vitamin C, and vitamin K.
Chicken brings lean protein.
- Family-friendly flavors: Cheesy, savory, and familiar—even picky eaters usually say yes.
- Flexible prep: Works with breast or thigh meat, fresh or frozen broccoli, and different cheeses.
- Great for leftovers: The sauce keeps the chicken moist, so it reheats well without turning rubbery.
Pitfalls to Watch Out For
- Watery bake: Skipping the broccoli pre-cook or not patting it dry can make the sauce thin. Par-cook and blot off moisture.
- Bland sauce: Under-seasoning is common. Taste the sauce before baking and adjust salt, pepper, and Dijon.
- Overcooked chicken: Small pieces cook quickly.
Check at 25 minutes and avoid long broiling.
- Curdled sauce: Boiling the sauce on the stove isn’t needed and can cause separation. Mix cold and bake gently.
- Too thick or too thin: If you prefer a looser sauce, add a splash more broth or cream. For thicker, reduce broth by 2–3 tablespoons.
Alternatives
- Protein swaps: Use rotisserie chicken (about 4 cups shredded) and reduce bake time to 15–20 minutes.
Turkey or cooked sausage also works.
- Veggie variations: Try cauliflower florets, green beans, or zucchini (salt and pat zucchini dry first). Keep the total volume similar to avoid overflow.
- Cheese options: Gruyère, Monterey Jack, or pepper jack can replace cheddar. A little blue cheese adds punch if you like it bold.
- Add-ins: Crisped bacon, sautéed mushrooms, or a pinch of red pepper flakes for heat.
Add 1–2 tablespoons of chopped scallions for freshness.
- Dairy adjustments: If you need to go lighter, swap sour cream for full-fat Greek yogurt. For ultra-rich, use all heavy cream and skip the broth.
