If you need a cozy dinner that feels a little “restaurant-ish” but takes almost no effort, this Chicken, Spinach, and Mushroom Bake is it. You get juicy baked chicken covered in a creamy mushroom sauce, tender sautéed mushrooms, wilted spinach, and a golden mozzarella topping that bubbles up perfectly in the oven.
This recipe is also super practical: it’s one baking dish, easy ingredients, and it works great for busy weeknights. Serve it with rice, mashed potatoes, pasta, or even just a simple salad—anything that can soak up that creamy sauce is a win.
Ingredients (Clean List)
- 4 boneless, skinless chicken breasts
- 2 cups fresh spinach, chopped
- 1 cup mushrooms, sliced
- 1 cup cream of mushroom soup
- 1/2 cup sour cream
- 1 cup mozzarella cheese, shredded
- 2 cloves garlic, minced
- 1 tablespoon olive oil
- 1 teaspoon Italian seasoning
- Salt, to taste
- Black pepper, to taste
Kitchen Tools You’ll Need
- Large skillet
- Mixing bowl
- 9×13-inch (or similar) baking dish
- Spoon or spatula
- Measuring cups/spoons
Step-by-Step Instructions (Clean Steps)
Step 1: Preheat the oven
Preheat your oven to 375°F (190°C).
Lightly grease a baking dish so nothing sticks and cleanup stays easy.
Step 2: Sauté the garlic
Place a skillet over medium heat and add 1 tablespoon olive oil.
Add the minced garlic and sauté for 1–2 minutes, just until it smells fragrant.
(Keep an eye on it—garlic can burn fast.)
Step 3: Cook the mushrooms
Add the sliced mushrooms to the skillet.
Cook for 5–7 minutes, stirring occasionally, until they become tender and release their moisture.
You’ll notice the mushrooms shrink a bit and the pan may look “wet” at first. That’s perfect—let that moisture cook off so the bake doesn’t turn watery.
Step 4: Wilt the spinach
Stir in the chopped spinach and cook for 2–3 minutes until wilted.
Turn off the heat and set the mushroom-spinach mixture aside.
Step 5: Mix the creamy sauce
In a mixing bowl, combine:
- cream of mushroom soup
- sour cream
- Italian seasoning
- salt and pepper
Mix until smooth and creamy.
Step 6: Arrange the chicken
Place the chicken breasts in the greased baking dish in a single layer.
If your chicken breasts are very thick, you can gently pound them to an even thickness so they cook more evenly (optional but helpful).
Step 7: Add mushrooms + spinach
Spread the cooked mushroom and spinach mixture evenly over the chicken.
Step 8: Pour the sauce and add cheese
Pour the creamy sauce over everything, making sure the chicken is well coated.
Sprinkle shredded mozzarella evenly over the top.
Step 9: Bake
Bake for 25–30 minutes, or until the chicken is fully cooked and the cheese is bubbly and lightly golden.
Chicken is done when it reaches 165°F (74°C) in the thickest part (if you use a thermometer). If not, slice the thickest breast—there should be no pink and the juices should run clear.
