Ingredients

• Cooked Chicken (2 cups): Shredded or diced, provides the hearty protein base essential for this keto casserole.
• Sliced Mushrooms (2 cups): Adds earthy flavor and a satisfying texture that pairs perfectly with creamy sauce.
• Heavy Cream (1 cup): Creates a rich, velvety sauce that binds all ingredients together harmoniously.
• Chicken Broth (1 cup): Adds depth and moisture, balancing the richness of the cream.
• Cream Cheese (1/2 cup, softened): Gives the casserole its signature creamy texture and slight tanginess.
• Shredded Mozzarella Cheese (1 cup): Melts beautifully to create a golden, gooey topping.
• Garlic (2 cloves, minced): Infuses aromatic flavor, enhancing the savory profile of the dish.
• Thyme (1 teaspoon): A fragrant herb that complements both chicken and mushrooms perfectly.
• Salt and Pepper: To taste, essential for seasoning and balancing flavors.
• Olive Oil: Used for sautéing mushrooms and garlic, adding a subtle fruity background.

Instructions

Preheat the Oven

Set your oven to 350°F (175°C) to ensure it’s at the right temperature for baking the casserole evenly and thoroughly. Preheating helps achieve a perfect bubbly and melted cheese topping.

Sauté Mushrooms and Garlic

Heat olive oil in a large skillet over medium heat. Add minced garlic and sliced mushrooms, cooking until mushrooms are tender and fragrant. This step intensifies their flavor and removes excess moisture, preventing sogginess in the casserole.

Mix the Creamy Sauce

In a mixing bowl, combine softened cream cheese, heavy cream, chicken broth, thyme, salt, and pepper. Whisk until the mixture is smooth and fully blended, ensuring the sauce will be creamy and flavorful throughout the casserole.

Combine Chicken and Mushroom Mixture

Add the cooked chicken and sautéed mushrooms with garlic into the creamy sauce mixture. Stir gently to evenly coat all ingredients with the sauce, ensuring every bite is rich and well-seasoned.

Transfer to Baking Dish and Top with Cheese

Pour the combined mixture into a greased 9×9-inch baking dish, spreading evenly. Sprinkle shredded mozzarella cheese over the top. This cheese will create a golden and bubbly crust as it bakes, adding texture and richness.

Bake Until Bubbly and Melted

Place the baking dish in the preheated oven and bake for 25-30 minutes. The casserole should be bubbly around the edges with melted golden cheese on top. Let it cool slightly before serving to allow the sauce to set and flavors to meld.

Storage Tips

Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven or microwave to maintain the creamy texture without drying out.

Serving Suggestions

This casserole pairs beautifully with a fresh green salad or steamed low-carb vegetables like asparagus or broccoli. For an added crunch, sprinkle some toasted almond slivers on top just before serving.

FAQs

Can I use raw chicken for this casserole?

This recipe calls for cooked chicken to reduce baking time and ensure even cooking. Using raw chicken would require longer baking to cook thoroughly.

Is this casserole suitable for other low-carb diets besides keto?

Yes, it works well for many low-carb and high-fat diets due to its ingredients, focusing on minimal carbs and healthy fats.

Can I freeze this casserole?

Yes, you can freeze it after baking. Wrap tightly and freeze for up to 2 months. Thaw in the refrigerator overnight before reheating.

What can I substitute for heavy cream if unavailable?

Coconut cream is a good dairy-free substitute but may slightly alter the flavor. Avoid milk as it’s too thin for this recipe.

Can I add other vegetables?

Absolutely! Low-carb veggies like spinach, zucchini, or kale can be added for extra nutrition and texture. Just sauté them alongside mushrooms.

Is it necessary to use cream cheese?

Cream cheese adds richness and helps thicken the sauce, but you can substitute with mascarpone for a milder flavor or omit for a lighter dish.

How can I make this recipe spicier?

Add a pinch of red pepper flakes with the garlic or sprinkle some cayenne pepper into the creamy sauce mixture for a subtle kick.
