Why You’ll Love This Creamy Keto Broccoli Chicken Casserole

This dish is high-protein, rich in flavor, and a dream come true for anyone on a low-carb or ketogenic diet. The combination of melted cheeses, juicy chicken, and perfectly cooked broccoli creates a savory experience that feels both indulgent and balanced.

Can I Use Frozen Broccoli or Pre-Cooked Chicken?

Ingredients for the Creamy Keto Broccoli Chicken Casserole

This casserole comes together with ingredients you likely already have in your fridge and pantry. Each component plays a role in adding flavor, texture, or that signature creamy goodness we all crave.

• Chicken breast: The lean protein base of the dish. You can also use thighs for extra flavor.
• Broccoli florets: Adds fiber, nutrients, and a nice crunch. Fresh or frozen works fine.
• Cream cheese: This is where the creaminess begins. It melts down into a rich, velvety sauce.
• Shredded cheddar cheese: A sharp, cheesy flavor that pulls everything together.
• Heavy cream: Helps loosen up the cream cheese and keeps the casserole saucy.
• Garlic powder: Adds subtle warmth and depth without overpowering the dish.
• Salt and black pepper: Essential seasonings to enhance every bite.
• Mozzarella cheese: Offers that gooey, stretchy topping that makes casseroles irresistible.

How To Make the Creamy Keto Broccoli Chicken Casserole

Step 1: Prepare the Ingredients

Start by preheating your oven to 375°F. While it heats, cook your chicken (if not using pre-cooked) and steam or microwave the broccoli until just tender.

Step 2: Make the Creamy Sauce

In a saucepan over medium heat, combine cream cheese and heavy cream. Stir until smooth, then mix in garlic powder, salt, and pepper. Once blended, fold in the cheddar cheese and let it melt.

Step 3: Assemble the Casserole

In a large mixing bowl, combine the cooked chicken and broccoli. Pour the cheesy sauce over and mix well. Transfer the mixture to a greased baking dish.

Step 4: Add the Finishing Touches

Top the casserole with shredded mozzarella cheese. Bake uncovered for 20 to 25 minutes, or until bubbly and golden on top.

Serving and Storing This Creamy Keto Broccoli Chicken Casserole

This casserole is satisfying enough to serve on its own, but also pairs wonderfully with a simple salad or keto-friendly bread. It feeds about 4 to 6 people depending on portion size and can be stored in an airtight container in the fridge for up to 4 days. Reheat in the microwave or oven until warmed through.
