Ingredients

2 cups cooked chicken, shredded
Using cooked chicken saves time and enhances flavor. Opt for rotisserie chicken for a quick prep or use leftovers from a previous meal. Shredded chicken combines well with the sauce, ensuring every bite is filled with taste.
8 oz mushrooms, sliced
Mushrooms add depth to the dish with their umami flavor. They also provide a nice texture contrast, soaking up the sauce beautifully. Choose any variety you like, such as cremini or button mushrooms for a mild taste.
4 cloves garlic, minced
Garlic is the heart of this casserole, infusing it with aromatic flavor. Besides enhancing taste, garlic also offers health benefits, with properties believed to boost immunity and provide anti-inflammatory effects.
1 cup heavy cream
Heavy cream creates a rich, velvety sauce that binds all the ingredients together. It's low in carbs, making it a perfect choice for keto diets, while providing a luxurious texture that elevates the dish.
1 cup grated cheddar cheese
Cheddar cheese adds a delicious, gooey element that complements the creaminess of the dish. It also introduces additional healthy fats, which are instrumental in a ketogenic diet.
1 tsp onion powder
Onion powder enhances the savory flavor profile without the need for fresh onions, which can add unnecessary carbohydrates. This powdered form blends seamlessly into the sauce.
1 tsp dried thyme
Thyme introduces an earthy aroma and flavor that pairs wonderfully with chicken. It also adds a hint of sophistication, making the dish feel elevated without extra effort.
Salt and pepper to taste
Seasoning is crucial for pulling together all the flavors. Adjust these to your preference to ensure the casserole is not only flavorful but perfectly suited to your palate.
2 tbsp olive oil
Olive oil is essential for sautéing the mushrooms and garlic, helping to release their flavors. This healthy fat also aligns with keto principles while enhancing the dish's texture.

Directions & Preparation

Step 1: Preheat the oven to 375°F (190°C).

Preheating the oven is a step that should never be overlooked when baking. It ensures your casserole cooks evenly and thoroughly from the moment it goes in. Set your oven to the correct temperature so that it’s hot and ready when you assemble your dish.

Step 2: Heat olive oil in a skillet over medium heat. Sauté the mushrooms until browned, about 6-8 minutes.

Sautéing the mushrooms releases their moisture and adds a deeper flavor through caramelization. Cook them until they're golden brown—this step not only enhances their taste but also creates a rich mushroom base for your casserole.

Step 3: Add minced garlic to the skillet and sauté for an additional 1-2 minutes until fragrant.

Adding garlic after the mushrooms ensures it doesn’t burn and turn bitter. The goal is to infuse the oils with its aroma and flavor, perfectly complementing the sautéed mushrooms. This will deliver an irresistible scent that fills your kitchen.

Step 4: In a large bowl, combine the shredded chicken, sautéed mushrooms and garlic, heavy cream, cheddar cheese, onion powder, thyme, salt, and pepper.

Mixing all the components in a bowl allows the flavors to meld together before baking. The cream and cheese will create a thick, aromatic sauce that envelops the chicken and mushrooms, ensuring that every bite is packed with deliciousness.

Step 5: Pour the mixture into a greased casserole dish, spreading it evenly.

Transferring your mixture into a greased casserole dish prevents sticking and makes serving easier later. Spread it out to ensure even cooking and optimal flavor distribution, setting the stage for a beautiful final result.

Step 6: Bake for 25-30 minutes until bubbly and the top is golden brown.

Baking the casserole allows the flavors to develop and the cheese to melt into a golden, crispy topping. Keep a close eye on it to avoid over-baking, which can dry out the dish. It’s ready when the edges are bubbling and the top is irresistibly appetizing.

Step 7: Let it cool for 5-10 minutes before serving.

Allowing the casserole to rest helps it set up, making it easier to serve and preventing burns. This cooling period enhances the flavors as well, giving the dish time to settle into a perfect blend of tastes.
