How to Make Keto Garlic Mushroom Chicken Casserole

Ingredients

  • 1 lb chicken breast, diced
  • 2 cups mushrooms, sliced
  • 1 cup heavy cream
  • 1 cup shredded cheese (e.g., cheddar or mozzarella)
  • 4 cloves garlic, minced
  • 1 tablespoon olive oil
  • Salt and pepper to taste
  • 1 teaspoon Italian seasoning (optional)
  • Fresh parsley for garnish (optional)

Keto Garlic Mushroom Chicken Casserole

Directions

  1. Preheat oven: Start by preheating your oven to 350°F (175°C). This first step is important to ensure your casserole cooks evenly.

  2. Sauté garlic: In a large skillet, heat olive oil over medium heat. Once hot, add minced garlic and sauté until it becomes fragrant. This usually takes about 1 to 2 minutes.

  3. Cook mushrooms: After the garlic is fragrant, add the sliced mushrooms to the skillet. Cook the mushrooms until they are soft and browned, which will take about 5 to 7 minutes. Stir them occasionally to ensure they cook evenly.

  4. Combine ingredients: In a large mixing bowl, combine the sautéed mushrooms, diced chicken, heavy cream, half of the shredded cheese, salt, pepper, and Italian seasoning if you’re using it. Mix everything together thoroughly so that the chicken is well coated.

  5. Transfer to casserole dish: Pour the mixture into a greased casserole dish. Make sure to spread it out evenly.

  6. Top with cheese: Sprinkle the remaining shredded cheese over the top of the casserole. This will create a delicious cheesy crust when it bakes.

  7. Bake: Place the casserole in the preheated oven and bake for 25-30 minutes. You’ll know it’s done when the chicken is cooked through and the casserole is bubbly.

  8. Garnish and serve: Once baked, take it out of the oven and let it cool for a few minutes. Garnish with fresh parsley if desired. Serve hot and enjoy your meal!

How to Serve Keto Garlic Mushroom Chicken Casserole

Keto Garlic Mushroom Chicken Casserole is versatile when it comes to serving. You can serve it straight from the oven into bowls, making it easy for guests to help themselves. Pair it with a side salad or steamed vegetables for a complete meal. If you’re feeling fancy, top each serving with a dollop of sour cream or a sprinkle of extra cheese.

This casserole can also be served with keto-friendly bread or cauliflower rice for those who like some additional texture or a bit of crunch.

How to Store Keto Garlic Mushroom Chicken Casserole

If you have leftovers, store them in an airtight container. The casserole can be kept in the refrigerator for up to 3 to 4 days. If you’re looking to keep it longer, consider freezing it. Make sure to wrap it tightly or place it in a freezer-safe container. It can be frozen for up to 2 months.

To reheat, simply thaw it in the refrigerator overnight and then warm it back up in the oven at 350°F (175°C) for about 20-25 minutes or until heated through.

Tips to Make Keto Garlic Mushroom Chicken Casserole

  • Choose the Right Chicken: Use fresh chicken breast for the best flavor. You can easily substitute with chicken thighs if you prefer a richer taste or juicier meat.

  • Mushroom Varieties: Feel free to experiment with different mushroom types like cremini or shiitake for varied flavors and textures.

  • Cream Alternatives: If you need a dairy-free version, you can use coconut cream. Note that this may slightly change the taste but it will still be creamy.

  • Cheese Options: Different cheeses can change the flavor profile of your casserole. Try using a blend of your favorites, like pepper jack for some heat or a smoky cheese for an added depth.

  • Spice it Up: If you enjoy a bit of heat, consider adding red pepper flakes into the mixture or serve with a spicy dipping sauce.

Variation

For a different twist, consider adding some vegetables to the mix. Broccoli, spinach, or bell peppers can be great additions that pair well with the chicken and mushrooms. Simply chop them up and add them along with the other ingredients.

You could also create a Mediterranean version by adding sun-dried tomatoes and feta cheese, giving the casserole a unique spin that is full of flavor.

FAQs

  • Can I make this recipe dairy-free?
    Yes! You can substitute heavy cream with coconut cream and use dairy-free cheese or skip the cheese altogether for a dairy-free version.

  • Can I use frozen chicken?
    While fresh chicken is recommended for best results, you can use cooked, shredded frozen chicken. Just adjust the baking time accordingly since the chicken wouldn’t need to cook as long.

  • Is this casserole keto-friendly?
    Absolutely! This casserole is low in carbohydrates and high in healthy fats, making it ideal for a keto diet. It’s a great way to enjoy a rich meal without compromising your dietary goals.

  • How can I add more flavor?
    Aside from the Italian seasoning, consider adding herbs like thyme or rosemary for an extra flavor burst. You could also try different flavor profiles with spices like paprika or Cajun seasoning.

With its rich flavors and satisfying texture, Keto Garlic Mushroom Chicken Casserole is a dish worth making again and again. It’s not just a meal; it’s a great way to gather and share good company over delicious food. Happy cooking!
