3) Ingredients for Keto Garlic Mushroom Chicken Casserole

Boneless, Skinless Chicken Breasts: The star of this casserole, the chicken breasts provide a lean source of protein. They’re juicy, tender, and soak up all the creamy goodness from the sauce. You could use chicken thighs too if you prefer something a little more flavorful.

Salt and Pepper: Sometimes, simple seasoning like salt and pepper is all you need. These basic seasonings bring out the best in the chicken and mushrooms, so don’t skip this step!

Mushrooms: Mushrooms add that earthy, savory flavor that pairs so well with garlic and cream. They’re the perfect addition to this casserole, giving it texture and depth. I usually go with white button mushrooms or cremini, but feel free to experiment with your favorite type.

Garlic: Garlic, garlic, garlic – I don’t think there’s a more comforting smell than sautéing garlic in butter. It adds that signature flavor and fragrance that makes the dish feel so comforting. Don’t skimp on it!

Heavy Cream: This is where the magic happens. Heavy cream is what makes the sauce rich and luscious. It’s the perfect ingredient to give this casserole that decadent, velvety texture.

Chicken Broth: A little bit of chicken broth adds moisture to the sauce, making it easier to coat the chicken and mushrooms. You can use low-sodium broth to keep things a bit healthier, but regular works just fine too.

Shredded Mozzarella Cheese: Mozzarella cheese brings the creaminess and the meltiness to this casserole. It’s a must for that golden, cheesy topping.

Grated Parmesan Cheese: Parmesan is the cherry on top. It adds a sharp, salty flavor that balances out the richness of the heavy cream. Don’t skip it!

Butter and Olive Oil: These fats are used for sautéing the garlic and mushrooms. A combination of butter and olive oil gives you that perfect balance of flavor and richness without going overboard.

Dried Thyme and Garlic Powder: These two herbs bring a little extra flavor. Thyme adds an herby earthiness, and garlic powder just enhances the garlic taste.

4) How to Make Keto Garlic Mushroom Chicken Casserole

Step 1: Preheat your oven to 375°F (190°C) and grease a 9×13-inch casserole dish. This is where all the magic will happen, so don’t forget to grease the dish to ensure everything comes out easily later.

Step 2: Season the chicken breasts with salt and pepper, and heat olive oil and butter in a large pan over medium heat. Sear the chicken for about 4-5 minutes per side until golden brown. This step is important because it locks in the flavor and juiciness of the chicken. Set the chicken aside once it’s done.

Step 3: In the same pan, add the sliced mushrooms and cook them until softened, about 5 minutes. Then, add the garlic and cook for another 1-2 minutes. The kitchen will start to smell amazing at this point! Stir in the chicken broth, heavy cream, garlic powder, and thyme. Let it all simmer for 3-4 minutes until the sauce starts to thicken up.

Step 4: Stir in the mozzarella and Parmesan cheese. The sauce will become nice and creamy as the cheese melts. Don’t rush this step – it’s where the magic happens!

Step 5: Return the chicken breasts to the pan, spoon some sauce over them, and transfer everything into the prepared casserole dish. Bake for about 20-25 minutes, or until the chicken is cooked through and the sauce is bubbly and golden on top.

Step 6: Once it’s out of the oven, garnish with fresh herbs and serve hot. This is the moment you’ve been waiting for – the cheesy, creamy casserole is ready to be devoured!

5) Tips for Making Keto Garlic Mushroom Chicken Casserole

Use Fresh Chicken: Fresh chicken breasts always yield the best results in this casserole. If you use frozen chicken, make sure to thaw it thoroughly before cooking to avoid uneven cooking.

Don’t Overcrowd the Pan: When searing the chicken or sautéing the mushrooms, make sure not to overcrowd the pan. Giving the ingredients some room to breathe will ensure they cook evenly and get that perfect texture.

Let the Sauce Thicken: If your sauce isn’t thickening as quickly as you’d like, just let it simmer for a bit longer. Be patient – the longer it simmers, the creamier it gets!

6) Making Keto Garlic Mushroom Chicken Casserole Ahead of Time

This casserole is actually great for meal prep. You can make it ahead of time and store it in the fridge for up to 2-3 days. Just prepare everything, and instead of baking it right away, cover the casserole and refrigerate it. When you’re ready to eat, just pop it in the oven to bake – easy peasy! Just keep in mind that the longer it sits, the more the flavors meld together, so it’ll only taste better the next day.

7) Storing Leftover Keto Garlic Mushroom Chicken Casserole

Store any leftovers in an airtight container in the fridge for up to 3 days. When you’re ready to eat, just reheat in the oven or microwave. You can even add a little extra mozzarella or Parmesan before reheating for that fresh-out-of-the-oven feel.
