Ingredients for Keto Chicken and Mushroom Casserole

This dish uses simple ingredients that are commonly found in keto kitchens. Here’s what you’ll need:

Salt and Pepper: To season the dish perfectly.

Chicken: Boneless, skinless chicken thighs or breasts.

Mushrooms: Cremini or white mushrooms for an earthy flavor.

Heavy Cream: Essential for that rich and creamy sauce.

Cream Cheese: Adds thickness and tang to the sauce.

Cheddar Cheese: Sharp or mild cheddar to top off the casserole.

Garlic: For a punch of flavor.

Butter: Adds richness to the mushrooms.

Olive Oil: For browning the chicken.

Fresh Thyme or Parsley: For garnish and a touch of freshness.

Tips and Tricks for the Perfect Casserole

• Use chicken thighs for juicier meat: While chicken breasts work, thighs tend to stay more moist and tender in casseroles.
• Don’t overcook the chicken: Since you’re searing the chicken first and then baking it, be careful not to overcook it in the skillet.
• Brown the mushrooms well: This adds depth to the flavor. The key is not to overcrowd the pan so they can sear instead of steam.
• Make it extra cheesy: Add a bit of mozzarella to the cheddar topping for a stretchier, gooey layer of cheese.

Delicious Variations to Try

This keto chicken and mushroom casserole is versatile! Here are some ways to tweak the recipe to suit your preferences:

Add veggies: Cauliflower or broccoli florets make this casserole even more filling and keto-friendly.

Add spinach: Stir in fresh spinach to the creamy sauce for extra greens.

Swap the cheese: Try using Gruyère, Parmesan, or Monterey Jack for different flavor profiles.

Add bacon: Crispy bacon bits are a tasty addition for a smokier, richer taste.

Try different mushrooms: Use shiitake or portobello mushrooms for a heartier texture.

How to Serve Keto Chicken and Mushroom Casserole

How to Store and Reheat Leftovers

Storing:

• Refrigerator: Store any leftovers in an airtight container in the fridge for up to 3-4 days.

Reheating:

• Oven: Reheat in a preheated oven at 350°F (175°C) for about 15-20 minutes until heated through.
• Microwave: You can also microwave individual portions for 2-3 minutes, though the oven will give a better texture.

Recipe FAQs
