Preparation Phase & Tools to Use
Before diving into this delightful recipe, it’s essential to prepare your kitchen for success. Start by gathering all the necessary ingredients and tools. You will need a large skillet, a 9×13-inch baking dish, and a mixing spoon. Ensure your oven is preheated to 375°F (190°C) to save time later. Additionally, have a cutting board and chef’s knife handy for chopping the onions, garlic, and any herbs you wish to garnish with later.
Clear your countertop to create a workspace that is efficient and organized. Getting all your ingredients prepped before cooking, such as slicing the mushrooms and dicing the onion, will streamline the process and help you stay focused. If you prefer to keep your kitchen clean and minimize dishes, consider using a single skillet for both the stove and the oven. Now, let’s move on to prepare this delicious dish!

Ingredients
- 1.5 pounds boneless skinless chicken breasts or thighs
- 8 ounces fresh mushrooms (button, cremini, or shiitake), sliced
- 5 ounces fresh baby spinach
- 1 small yellow onion, diced
- 3 cloves garlic, minced
- 1 cup heavy cream (or coconut cream for dairy-free)
- 1½ cups shredded mozzarella cheese (or cheese of choice)
- ¼ cup grated Parmesan cheese (optional, for topping)
- 2 tablespoons olive oil or butter
- 1 teaspoon salt
- ½ teaspoon black pepper
- ¼ teaspoon red pepper flakes (optional, for spice)
Instructions
Step 1: Preheat and Prepare the Dish
Start by preheating your oven to 375°F (190°C). Meanwhile, take a moment to lightly grease your baking dish with a bit of olive oil or butter, ensuring an easy release for the baked chicken later. This step is crucial for achieving that perfect golden-brown crust.
Step 2: Sear the Chicken
In a large skillet, heat olive oil or butter over medium-high heat. Once hot, add the chicken pieces and sear for about 2–3 minutes on each side, or until they develop a beautiful golden color. This initial searing will lock in the juices and flavor of the chicken. Once done, remove the chicken from the skillet and set it aside.
Step 3: Sauté the Vegetables
Using the same skillet, add the diced onions and minced garlic. Sauté for 1–2 minutes until fragrant and the onions become translucent. Next, sprinkle in the sliced mushrooms and cook until they are beautifully browned and the moisture has mostly evaporated, about 5–6 minutes. This will add depth of flavor to your dish as the mushrooms will soak up the deliciousness left in the pan.
Step 4: Incorporate the Spinach
Add the fresh spinach to the skillet and cook briefly until just wilted. This usually takes less than a minute, as you want the spinach to retain its vibrant color and nutrition. Once wilted, pour in the heavy cream, stirring to combine all the ingredients. Allow the mixture to simmer for 1–2 minutes, thickening slightly. If desired, mix in a handful of shredded cheese at this stage for an even creamier sauce.
Step 5: Assemble the Bake
Carefully transfer the mushroom-spinach mixture to your greased baking dish. Place the seared chicken pieces over this layer and pour the creamy mixture evenly over the top. For an extra cheesy delight, sprinkle the remaining mozzarella and optional Parmesan cheese on top. This will create a deliciously gooey topping as it bakes.
Step 6: Bake and Serve
Place the assembled dish in the preheated oven and bake uncovered for 25–30 minutes or until the cheese is bubbly and the chicken reaches an internal temperature of 165°F (74°C). After baking, let it rest for about 5 minutes to allow the flavors to settle. This makes for a more enjoyable dining experience. Before serving, consider garnishing with fresh herbs or a sprinkling of additional cheese if desired.

Variations
- Protein: Swap out the chicken for turkey or even tofu for a vegetarian option.
- Vegetables: Include other vegetables such as bell peppers, zucchini, or asparagus for added texture and flavor.
- Spices: If you like a little heat, add more red pepper flakes or try a dash of cayenne pepper.
Cooking Notes
- For the best flavor, use fresh herbs like thyme or basil—it elevates the dish.
- Make sure to adjust cooking times according to the thickness of your chicken pieces; thicker pieces may require a few extra minutes.
Serving Suggestions
- Pair this bake with a crisp green salad for a refreshing contrast.
- Serve with cauliflower rice or zucchini noodles for a complete low-carb meal.
