Step by Step Directions

Step 1: Prepare the Chicken

Begin by preheating your oven to 375°F (190°C). While the oven heats up, grab your chicken thighs. Trim any excess fat and cut them into bite-sized pieces. In a skillet, heat 1 tablespoon of olive oil over medium-high heat. Once the oil is shimmering, add the chicken pieces. 

Season with salt, black pepper, smoked paprika, and garlic powder. Sauté until golden brown and cooked through, about 5-7 minutes.

Step 2: Cook the Vegetables

In the same skillet, add the remaining olive oil and toss in the broccoli florets and sliced leeks. Cook these until the broccoli is bright green and slightly tender, around 3-4 minutes. You want the veggies to maintain some crunch as they will continue to cook in the oven.

Step 3: Make the Creamy Sauce

In a mixing bowl, combine the heavy cream, yogurt, mustard, and half of the Parmesan cheese. Whisk until well mixed and smooth. This creamy mixture will provide a luscious texture to our casserole.

Step 4: Assemble the Casserole

In a large mixing bowl, combine the sautéed chicken and vegetables. Pour the creamy sauce over the mixture and stir until everything is well coated. Transfer this mixture into a greased baking dish.

Step 5: Add Cheese

Sprinkle the remaining Parmesan cheese over the top, followed by the cheddar cheese. This will create a delicious cheesy crust as it bakes.

Step 6: Bake

Cover the dish with aluminum foil and bake in the preheated oven for 20 minutes. After this time, remove the foil and bake for an additional 10-15 minutes until the cheese is bubbly and golden.

Step 7: Serve

Once done, take the casserole out of the oven and let it cool for a few minutes before serving. This dish can be enjoyed hot, and it will smell divine!

Tips On Making Keto Chicken Casserole

  • Choose Quality Chicken: Use fresh, high-quality chicken thighs for the best flavor and texture. Frozen chicken is fine but make sure to thaw it completely before cooking.
  • Experiment with Spices: Add your favorite spices or herbs like thyme or Italian seasoning for extra flavor.
  • Don’t Skimp on Cheese: Using a blend of cheeses can elevate the flavor complexity. Try adding some mozzarella or gouda.
  • Prep Ahead: You can mix the ingredients ahead of time and store in the fridge until you’re ready to bake, making it perfect for meal prep.
  • Keep it Moist: Consider adding a bit more cream or broth if you prefer a creamier consistency.

How Do You Store This Keto Chicken Casserole?

Store any leftovers in an airtight container in the refrigerator for up to 3 days. When you’re ready to enjoy it again, simply reheat in the oven or microwave until warmed through. 

If you need to keep it longer, consider freezing the casserole before baking. It can last in the freezer for up to 2 months. Just remember to thaw it in the fridge overnight before baking.

What Other Substitutes Can You Use in Keto Chicken Casserole?

  • Cauliflower Florets: Instead of broccoli, you can use cauliflower for a different flavor profile and texture.
  • Zucchini Noodles: Swap out the chicken for shredded zucchini for a vegetarian twist.
  • Ground Turkey: Use ground turkey if you prefer a different protein source. It cooks faster and makes for a different texture.
  • Spinach: Fresh or frozen spinach can add extra nutrients. Just be sure to squeeze out excess moisture if using frozen.
  • Vegan Cheese: If you’re looking for a dairy-free option, consider using vegan cheese alternatives that melt well.
