Preparation Phase & Tools to Use
Before you start cooking, it’s vital to prepare your kitchen and gather all necessary tools to streamline the cooking process. Begin by preheating your oven to 375°F (190°C) so it’s hot and ready once your dish is assembled. Take out a 9×13-inch baking dish and lightly grease it to prevent any sticking during baking.
For cooking, ensure you have a large skillet where you can sear your chicken and sauté the vegetables. A sharp knife and cutting board will help you chop your onion and garlic easily. Measuring cups, a whisk or spoon for mixing, and a spatula for transferring the ingredients will be handy. Keeping everything organized will ensure you create a seamless cooking experience!

Ingredients
- 1.5 lbs boneless skinless chicken breasts or thighs
- 8 oz fresh mushrooms, sliced
- 5 oz baby spinach
- 1 small yellow onion, diced
- 3 garlic cloves, minced
- 1 cup heavy cream (or coconut cream for dairy-free)
- 1½ cups shredded mozzarella cheese
- ¼ cup grated Parmesan (optional)
- 2 tbsp olive oil or butter
- 1 tsp salt
- ½ tsp black pepper
- ¼ tsp red pepper flakes (optional)
Instructions
Step 1: Preheat the Oven
First, preheat your oven to 375°F (190°C). This step ensures that the oven reaches a consistent temperature, which is crucial for even baking and browning of your chicken bake.
Step 2: Sear the Chicken
In a large skillet, add 2 tablespoons of olive oil or butter over medium-high heat. Once the oil is hot, add the chicken breasts or thighs, which have been seasoned with salt, pepper, and optional red pepper flakes. Sear each side for about 2–3 minutes until golden brown—this step enhances the flavor through caramelization. After searing, set the chicken aside to rest.
Step 3: Sauté the Vegetables
In the same skillet, add the diced onion and minced garlic. Sauté for 1–2 minutes, stirring frequently until fragrant. Next, add the sliced mushrooms and cook for approximately 5–6 minutes until they are nicely browned and reduce in size. Finally, stir in the baby spinach and let it wilt for a minute or two, creating a vibrant mixture.
Step 4: Create the Cream Sauce
Pour the heavy cream or coconut cream into the skillet with the sautéed vegetables. Stir this mixture thoroughly, allowing it to simmer for 1–2 minutes. If desired, you can mix in a handful of shredded mozzarella cheese to thicken the sauce and add extra creaminess, making it even more indulgent!
Step 5: Assemble the Bake
Transfer the mushroom and spinach mixture into your greased baking dish, spreading it evenly across the bottom. Place the seared chicken on top, allowing the flavors of the spinach and mushrooms to soak into the chicken. Pour the creamy sauce over the chicken, ensuring each piece is covered.
Step 6: Add Cheese & Bake
Sprinkle the remaining shredded mozzarella cheese over the top, followed by the grated Parmesan cheese if you choose to use it. This cheesy layer will create a delightful crust as it bakes. Place the dish uncovered into your preheated oven and bake for about 25–30 minutes. Keep an eye on the dish until the cheese is bubbly and golden, and the chicken reaches an internal temperature of 165°F (74°C).
Step 7: Rest & Serve
Once baked, allow the dish to rest for about 5 minutes before serving. This resting time lets the flavors meld and makes for easier serving. You may garnish with fresh herbs if desired and serve warm, enjoying every bite of this comforting, low-carb delight!

Variations
- Protein: Swap chicken for turkey or ground beef; both options work seamlessly with the creamy sauce.
- Vegetables: Consider adding bell peppers, broccoli, or zucchini for added nutrition and variety.
- Spices: Experiment with your favorite spices such as Italian seasoning, oregano, or basil for a personalized touch.

- Using a dairy-free cream alternative like coconut cream allows those on a dairy-free diet to enjoy this dish without compromising on taste.
- Check the doneness of the chicken with a meat thermometer for perfect cooking without drying it out.
Serving Suggestions
- Pair your low-carb bake with a fresh garden salad drizzled with a tangy vinaigrette for a well-rounded meal.
