Step 1: Preheat the Oven

Preheat your oven to 400°F (200°C).

Step 2: Prepare the Lasagna Filling

In a bowl, combine ricotta cheese, Parmesan cheese, egg, Italian seasoning, salt, and pepper. Mix well until smooth. Set aside—this will be your lasagna-style stuffing.

Step 3: Season the Chicken

Season each chicken breast generously on both sides with salt and pepper.

Step 4: Create the Chicken Pocket

Using a sharp knife, carefully slice each chicken breast horizontally to create a pocket without cutting all the way through.

Step 5: Add Marinara

Place a spoonful of marinara sauce inside each chicken pocket and spread it evenly with the back of the spoon.

Step 6: Stuff the Chicken

Fill each chicken breast with an even portion of the ricotta lasagna filling.

Step 7: Add Sauce and Cheese

Place the stuffed chicken breasts in a baking dish.
Spoon the remaining marinara sauce over the top and sprinkle with shredded mozzarella cheese.

Step 8: Bake

Bake in the oven for 35 minutes, or until the chicken is fully cooked and no longer pink.
The internal temperature should reach 165°F (74°C) in the thickest part.

Step 9: Garnish and Serve

Remove from the oven and garnish with fresh basil before serving.
