A cheesy casserole combined with tender chicken, bacon, leeks, and spinach in a deliciously cheesy sauce.

While it’s best enjoyed freshly cooked, you can easily prepare and mix all of the ingredients ahead of time in a pan. When you're ready, pop it in the oven to bake to save time.

We used mozzarella cheese but feel free to use cheddar, edam or gouda cheese instead. They melt just as well and turn golden brown and bubbly in the oven!

Cheesy Chicken Casserole Ingredients

This low carb casserole only requires 10 key ingredients to make, and they're easily substitutable to what you have on hand.

• Chicken - we used skinless, boneless chicken breast for this recipe, but you can easily use chicken thighs or other meat.
• Bacon - who doesn't love extra bacon in casseroles? You can also add diced ham if you don't have any bacon.
• Vegetables - we use baby spinach, red onion, and leek in this casserole. You can also use other low carb vegetables such as mushrooms, tomatoes, broccoli, and celery.
• Heavy cream
• Eggs
• Cheese - we used mozzarella in this recipe, but you can substitute it for cheddar, Edam, or gouda which all work great in this casserole.
• Olive oil
• Seasonings - for this recipe, you'll only need mild paprika, salt, and black pepper.

How To Make Keto Chicken Casserole

Step 1

Preheat the oven to 375 degrees Fahrenheit (190 degrees Celsius) and prepare an oven-proof dish for the casserole.

Step 2

Take a deep pan and heat the olive oil over medium-high heat. Add the chicken and sauté for 2 to 3 minutes, seasoning with a pinch of salt, pepper, and paprika.

Step 3

Add the onions and leeks and cook for a further 5 minutes while stirring occasionally.

Step 4

Stir in the bacon and spinach, then continue to cook for 2 to 3 minutes while stirring to combine all the flavors.

Step 5

Pour in the cream and whisk in the eggs. When the cream starts to bubble, add the cheese and season with salt, pepper, and paprika. Transfer everything to the oven-proof dish you prepared earlier.

Step 6

Bake for 10 to 15 minutes in the oven until golden brown. Slice into portions and serve hot!
