🥘 Ingredients You’ll Need
Here’s everything you need to make this creamy, comforting keto casserole:
Main Ingredients
- 2 tablespoons butter (grass-fed if possible)
- 1 tablespoon olive oil
- 1 ½ lbs chicken breast, cut into bite-sized pieces
- 8 oz mushrooms, sliced (baby bella or cremini work best)
- 4 cloves garlic, minced
- 1 cup heavy cream
- ½ cup chicken broth
- 4 oz cream cheese, softened
- 1 ½ cups shredded mozzarella cheese
- ½ cup grated Parmesan cheese
- Salt and pepper, to taste
- ½ teaspoon smoked paprika
- Fresh parsley, chopped, for garnish
🧀 Optional: Add a handful of spinach or broccoli florets for extra nutrients and color.
🔥 Step-by-Step Instructions
Step 1: Prep and Preheat
Preheat your oven to 375°F (190°C).
Grease a medium-sized baking dish (8×8 or 9×9) lightly with butter or olive oil.
Step 2: Cook the Chicken
In a large skillet, heat 1 tbsp olive oil and 1 tbsp butter over medium heat.
Add the chicken pieces, season with salt, pepper, and paprika, and cook until they’re lightly golden (about 4–5 minutes).
They don’t need to be fully cooked — just seared. Remove and set aside.
Step 3: Sauté the Mushrooms and Garlic
In the same pan, melt the remaining butter. Add the mushrooms and cook until tender and browned (5–6 minutes).
Add minced garlic and sauté until fragrant (1 minute).
🍄 Your kitchen will start smelling amazing at this point — earthy mushrooms and garlic are a match made in keto heaven.
Step 4: Make the Cream Sauce
Lower the heat to medium-low. Add the cream cheese, stirring until it starts to melt.
Pour in heavy cream and chicken broth, whisking gently to create a smooth sauce.
Add Parmesan cheese, then taste and season with salt and pepper as needed.

Step 5: Combine and Bake
Return the cooked chicken to the pan and coat with the creamy sauce.
Transfer everything into your greased casserole dish.
Top evenly with shredded mozzarella cheese.
Bake uncovered for 20–25 minutes, or until bubbly and golden on top.
Step 6: Garnish and Serve
Let it rest for 5 minutes before serving. Sprinkle with chopped parsley for that final fresh touch.
🥄 Creamy, garlicky, cheesy — it’s hard to believe this recipe is actually keto-friendly.
