📝 Ingredients

For the Chicken

1 cup almond flour
½ cup grated Parmesan cheese
1 teaspoon garlic powder
1 teaspoon onion powder
1 teaspoon Italian seasoning
½ teaspoon paprika
1 teaspoon salt
½ teaspoon black pepper
2 large eggs, beaten
2 tablespoons olive oil

For the Topping

In a shallow bowl, combine almond flour, Parmesan cheese, garlic powder, onion powder, Italian seasoning, paprika, salt, and pepper.
Dip each chicken breast into the beaten eggs, then coat evenly in the almond flour mixture.
Heat olive oil in a large skillet over medium heat. Cook the chicken for 3–4 minutes per side until lightly golden but not fully cooked.
Arrange the browned chicken in the prepared baking dish.
Spoon sugar-free marinara sauce evenly over each piece of chicken.
