How To Make the Creamy Keto Broccoli Chicken Casserole

Bringing this comforting casserole together is simple and straightforward. Follow these steps for a perfect result every time:

Step 1: Preheat and Prep

Start by preheating your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.

Step 2: Cook the Chicken

If you’re not using rotisserie or pre-cooked chicken, season chicken breasts or thighs with salt and pepper, then cook in a skillet until just done. Dice or shred the chicken and set aside.

Step 3: Blanch the Broccoli

Bring a pot of water to a boil and blanch the broccoli florets for 2–3 minutes, just until bright green and crisp-tender. Drain and set aside.

Step 4: Make the Creamy Sauce

In a saucepan over medium heat, combine cream cheese, heavy cream, garlic powder, onion powder, salt, and pepper. Stir until smooth and creamy, then mix in half of the shredded cheddar cheese.

Step 5: Assemble the Casserole

Add the cooked chicken and broccoli to your baking dish. Pour the creamy sauce over the top and toss to combine. Sprinkle the remaining cheddar cheese evenly over everything. Add a pinch of crushed red pepper or Italian seasoning if you like.

Step 6: Bake to Perfection

Bake for 20–25 minutes, or until the casserole is hot and bubbly with a golden-brown top. Let it cool for a few minutes before serving.
