Ingredients List – Fresh, Wholesome & Keto-Approved
Here’s everything you need to make this irresistible dish:
Main Ingredients
- 2 large boneless, skinless chicken breasts, diced
- 2 tablespoons olive oil
- 2 cups fresh spinach, chopped
- 1 ½ cups fresh mushrooms, sliced
- 1 small yellow onion, diced
- 2 garlic cloves, minced
- 1 cup heavy cream
- ½ cup grated parmesan cheese
- 1 cup shredded mozzarella cheese
- Salt and pepper to taste
- 1 teaspoon dried thyme
- 1 teaspoon smoked paprika
These ingredients provide depth, richness, and balance without going overboard on carbohydrates.
Step-by-Step Cooking Instructions
Step 1: Prepare the Oven and Pan
Preheat your oven to 375°F (190°C). Lightly grease a large oven-safe baking dish with olive oil or non-stick cooking spray. This will help keep cleanup easy and prevent sticking.
Step 2: Brown the Chicken
Heat olive oil in a large skillet over medium heat. Add the diced chicken, seasoning it with salt, pepper, paprika, and thyme. Cook until all sides are golden and the chicken is nearly cooked through. This will seal in the juices and build flavor.
Step 3: Cook the Vegetables
In the same skillet, toss in the onions and sauté until translucent. Add mushrooms and stir frequently until they release their moisture and turn golden brown. Add the garlic and cook for 30–60 seconds until fragrant. Finally, stir in the spinach and let it wilt completely. Remove the skillet from heat.
Step 4: Make the Sauce
Lower the heat and return the skillet to the burner. Pour in the heavy cream, stirring gently to blend it with the remaining juices. Add parmesan cheese and stir until the sauce thickens slightly and becomes creamy. Adjust salt and pepper to taste.
Step 5: Assemble and Bake
Mix the cooked chicken into the creamy vegetable mixture. Pour everything into your prepared baking dish. Top evenly with shredded mozzarella cheese.
Bake uncovered for 20 to 25 minutes, or until the cheese is bubbling and slightly golden.
