Ingredients

• 6 thin-sliced chicken breasts
• 1 small bag fresh baby spinach
• 1 container green onion cream cheese
• 8 oz shredded mozzarella cheese
• 1 dash pepper
• 1 dash herb and garlic seasoning
• 1/4 cup olive oil
• 1 cup sliced mushrooms (optional but recommended)

Tools You’ll Need

• 9×13 baking dish
• Mixing bowl
• Knife
• Cutting board
• Measuring tools
• Aluminum foil (optional)

Ingredient Additions & Substitutions

• Use plain cream cheese if you prefer milder flavor
• Replace spinach with kale or Swiss chard
• Add cherry tomatoes for brightness
• Swap mozzarella for Monterey Jack or provolone
• Add crushed red pepper for heat
• Use chicken thighs instead of breasts
• Add cooked bacon pieces for smoky richness

Step-by-Step Instructions

1. Preheat the Oven

Set your oven to 375°F (190°C).

2. Prepare the Chicken

Lay the thin-sliced chicken breasts in a greased 9×13 baking dish. Drizzle with olive oil. Sprinkle with pepper and herb & garlic seasoning.

3. Add the Spinach

Spread the fresh baby spinach evenly across the chicken. Don’t worry if it seems like a lot—it cooks down beautifully.

4. Add Mushrooms (Optional but Delicious!)

Scatter sliced mushrooms over the spinach for rich, earthy flavor.

5. Add the Cream Cheese

Drop spoonfuls of the green onion cream cheese evenly across the dish. It will melt into a creamy sauce as it bakes.

6. Top with Mozzarella

Sprinkle 8 oz shredded mozzarella over the top to create that irresistible golden bubbly crust.

7. Bake

Cover with foil for the first 20 minutes to keep everything moist. Remove foil and bake another 20–25 minutes, or until the chicken is cooked through and the cheese is melted and lightly browned.

8. Serve

Let rest for 5 minutes before serving so the sauce thickens slightly.
