I’ve included everything below to make this recipe easy to follow at home. For the full printable recipe instructions and ingredient quantities, scroll to the Recipe card at the bottom of this post.
- Cooked Chicken Breast: Leftover rotisserie chicken works amazingly well here. It creates a hearty, high-protein base that absorbs the savory cream sauce effortlessly.
- Broccoli Florets: Fresh or lightly steamed broccoli provides a wonderful green bite. It adds fiber and holds up nicely under heavy melted cheese.
- Cremini Mushrooms: Earthy sliced mushrooms bring deep savory umami to every bite. They soften in butter and enhance the overall texture seamlessly.
- Heavy Cream: Rich cream forms the backbone of our low-carb garlic sauce. It thickens naturally without requiring any flour or cornstarch.
- Cream Cheese: Softened cream cheese creates a silky, lush coating for the chicken. It ensures the casserole stays moist during baking.
- Cheddar & Mozzarella: A blend of shredded cheeses provides sharp flavor and stretch. It melts into a golden, bubbly top layer.
How to Make Cheesy Keto Chicken Broccoli Casserole
I’ve included everything below to make this recipe easy to follow at home. For the full printable recipe instructions and ingredient quantities, scroll to the Recipe card at the bottom of this post.
- Preheat your oven to 375°F (190°C) and lightly grease a standard 9x13-inch ceramic baking dish.
- Heat one tablespoon of butter in a large skillet over medium-high heat for two minutes.
- Add sliced mushrooms and cook for five minutes until browned and tender.
- Reduce heat to medium, then stir in cream cheese, heavy cream, garlic powder, salt, and black pepper for three minutes until smooth.
- Combine cooked chicken, steamed broccoli florets, and the warm cream sauce inside your prepared baking dish.
- Top evenly with shredded cheddar and mozzarella cheese.
- Bake uncovered at 375°F (190°C) for twenty minutes until the cheese is melted, golden, and bubbling around the edges.
Pro Tip: Par-steam your broccoli florets for just two minutes before assembling. Consequently, this prevents excess moisture from watering down your thick cream sauce while baking.
Common Mistakes to Avoid:
- Using raw, wet broccoli: Steam briefly and pat dry to avoid a watery sauce base.
- Overcooking the mushrooms: Sauté them quickly over medium-high heat so they brown instead of steaming.
- Baking too long: Remove the dish once the cheese bubbles to keep the chicken juicy.
Required Equipment:
- Large Skillet: Browns mushrooms evenly and warms the velvety garlic cream sauce.
- 9x13 Baking Dish: Holds all ingredients comfortably for even baking and melted cheese.
- Cheese Grater: Shreds fresh cheese easily for superior melting quality and texture.
Caleb's Recipe Tips
- Stir in a teaspoon of Dijon mustard to elevate the rich cheddar sauce.
- Use freshly grated cheese because pre-shredded bags contain starch anti-caking agents.
- Swap chicken breasts for juicy chicken thighs if you prefer higher fat macros.
- Sprinkle crushed pork rinds on top before baking for an optional crispy crunch.
Storage Instructions
- Refrigerator Storage: Store leftovers in airtight containers for up to four days.
- Freezer Storage: Freeze tightly wrapped portions for up to two months effortlessly.
- Reheating Tips: Reheat individual portions in the microwave or warm in the oven at 350°F (175°C) until hot.
