Ingredients
For the Chicken
- 4 boneless, skinless chicken breasts (6–8 ounces each)
- Salt and freshly ground black pepper, to taste
- 1 teaspoon garlic powder
- 1 teaspoon paprika
- 1 tablespoon olive oil
For the Filling
- 2 teaspoons olive oil
- 1 small onion, finely diced
- 2 cloves garlic, minced
- 8 ounces mushrooms, finely chopped
- 4 cups fresh spinach, roughly chopped
- 1/4 teaspoon salt
- 1/4 teaspoon black pepper
- 1/4 teaspoon red pepper flakes (optional)
- 1/2 cup shredded mozzarella or Swiss cheese
- 1/4 cup grated Parmesan cheese
Optional Sauce
- 1/2 cup low-sodium chicken broth
- 1/4 cup white wine or additional broth
- 1 teaspoon Dijon mustard
- 1 teaspoon olive oil
- Salt and pepper, to taste
Step 1: Prepare the Filling
Heat 2 teaspoons of olive oil in a skillet over medium heat.
Add the diced onion and cook for 3–4 minutes until softened.
Add garlic and cook for 30 seconds until fragrant.
Add chopped mushrooms, salt, pepper, and red pepper flakes if using. Sauté for 5–6 minutes until mushrooms release their moisture and begin to brown.
Add the spinach and cook for 2–3 minutes until wilted. Remove from heat and let cool slightly.
Once cooled, stir in mozzarella and Parmesan cheese. This mixture will be the filling for the chicken.
Step 2: Prepare the Chicken
Preheat the oven to 375°F (190°C).
Using a sharp knife, carefully slice a pocket into the thickest part of each chicken breast, being careful not to cut all the way through.
Season both sides of the chicken breasts with salt, black pepper, garlic powder, and paprika.
Step 3: Stuff the Chicken
Spoon the spinach and mushroom mixture into each chicken breast pocket, dividing evenly among the breasts.
Use toothpicks to secure the openings if needed to prevent the filling from spilling out during cooking.
Step 4: Sear the Chicken
Heat 1 tablespoon of olive oil in an oven-safe skillet over medium-high heat.
Add the stuffed chicken breasts and sear for 2–3 minutes on each side until lightly golden.
This step helps lock in moisture and adds flavor before baking.
Step 5: Bake the Chicken
Transfer the skillet to the preheated oven.
Bake for 20–25 minutes, or until the chicken reaches an internal temperature of 165°F (74°C).
Remove from oven and let the chicken rest for 5 minutes before slicing.
Step 6: Optional Pan Sauce
While the chicken rests, you can make a quick pan sauce.
Place the skillet back on medium heat (careful, handle may be hot).
Add chicken broth, white wine (if using), Dijon mustard, and a teaspoon of olive oil.
Simmer for 3–4 minutes, scraping up any browned bits from the pan.
Season with salt and pepper to taste. Drizzle over the stuffed chicken before serving.
Step 7: Serve
Serve the Spinach and Mushroom Stuffed Chicken with your choice of sides, such as:
- Roasted vegetables
- Mashed potatoes or cauliflower mash
- Quinoa or rice
- A light green salad
