Keto Chicken Broccoli Casserole Recipe

Introduction

This Keto Chicken Broccoli Casserole is a creamy, cheesy dish that’s perfect for low-carb meals. Packed with tender chicken and fresh broccoli, it combines rich flavors and comforting textures in a quick, one-pan recipe.

Ingredients

• 2 tbsp butter, divided
• 16 ounces broccoli, coarsely chopped
• 4 cloves garlic, minced
• 3/4 cup heavy whipping cream
• 1 1/3 cups shredded mozzarella, divided
• 1/3 cup grated parmesan cheese
• Salt and pepper, to taste
• 1 1/2 lb cooked, chopped chicken (about 4 cups)

Instructions

1. Step 1: Set a 10-inch ovenproof skillet over medium heat and add 1 tablespoon of the butter. Once melted, add the broccoli and sauté until bright green and just tender, about 4 minutes. Remove the broccoli to a bowl.
2. Step 2: Melt the remaining butter in the pan and add the garlic, cooking until fragrant, about 1 minute. Add the heavy cream and bring to a simmer, then cook until reduced and thickened, about 3 to 5 minutes.
3. Step 3: Stir in 1/3 cup of the mozzarella and all of the parmesan cheese until melted and smooth. Season with salt and pepper to taste.
4. Step 4: Stir in the cooked broccoli and chopped chicken, then top with the remaining 1 cup of mozzarella cheese.
5. Step 5: Preheat the broiler. Place the pan about 6 inches from the heat and broil until the cheese is beginning to brown, 2 to 5 minutes, watching closely to avoid burning.

Tips & Variations

• Use fresh or frozen broccoli; if frozen, thaw and drain excess water before cooking to avoid sogginess.
• For extra flavor, add a pinch of red pepper flakes or smoked paprika to the cream sauce.
• Substitute cooked turkey or leftover roast chicken if desired.
• If you don’t have an ovenproof skillet, transfer the mixture to a baking dish before broiling.

Storage

Store leftovers covered in the refrigerator for up to 3 days. Reheat gently in the microwave or in a low oven until warmed through. This casserole also freezes well—place in an airtight container and freeze for up to 2 months. Thaw overnight in the fridge before reheating.

FAQs

Can I use raw chicken instead of cooked chicken?

This recipe calls for cooked chicken to keep the cooking time short. If using raw chicken, cook it thoroughly first before adding to the casserole to ensure food safety.

What can I use instead of heavy cream?

You can substitute full-fat coconut milk or a mix of cream cheese and milk for a lower-carb alternative, but heavy cream provides the best texture and richness.

Notes

• Use cooked chicken from leftovers or rotisserie chicken for convenience.
• Broccoli can be substituted with cauliflower for variation.
• Adjust seasoning with salt and pepper as needed after broiling, since cheese adds saltiness.
• If your skillet is not ovenproof, transfer the mixture to a baking dish before broiling.
• Watch the broiler closely as cheese can burn quickly.
