Preheat the oven to 425°F. On a baking sheet, spread 2 tsp olive oil to grease your pan. Set aside.

In a medium bowl mix together, gluten free breadcrumbs, grated parmesan, cornstarch, garlic powder, Italian seasoning, salt, and pepper. Mix together the breading with a fork.

Drizzle remaining 2 tsp olive over chicken breast cutlets and toss to evenly coat chicken with oil. Place a chicken cutlet, one at a time, in the breading mixture. Press down slightly and use the fork to flip over and coat other side. Transfer breaded chicken to the greased baking sheet and repeat with remaining chicken.

Bake for 10 minutes, flip chicken, and then continue cooking for 5-10 minutes more, or until internal temperature reaches 165°F. Remove from oven, move oven rack to upper position, and preheat broiler.

Move baked chicken together so it is all in the middle of the pan. Sprinkle grated cheese over top.

Broil for 2 minutes, or until the cheese is melted and starts to brown. Top with marinara sauce and garnish with fresh basil. Serve with your favorite gluten free pasta, vegetables, or salad!
