Step 1: Prepare the Chicken: Cut chicken breasts into bite-sized pieces, approximately 1-inch in size. Ensure pieces are uniform in size for even cooking.
Step 2: Prepare the Breading: In a shallow dish, combine almond flour (or panko), Parmesan cheese (if using), garlic powder, onion powder, paprika, and black pepper. Mix thoroughly to ensure even distribution of seasonings.
Step 3: Set up the Breading Station: Place the beaten egg in a separate shallow dish. This creates a simple dipping station to properly coat the chicken.
Step 4: Bread the Chicken: Dip each piece of chicken into the beaten egg, allowing excess to drip off. Then, dredge the chicken in the breading mixture, pressing gently to ensure the breading adheres to all sides.
Step 5: Arrange on Baking Sheet: Preheat the oven to 400F (200C). Line a baking sheet with parchment paper. Arrange the breaded chicken nuggets in a single layer on the prepared baking sheet, ensuring they are not overcrowded.
Step 6: Bake the Nuggets: Drizzle the chicken nuggets with olive oil or avocado oil. Bake for 20-25 minutes, or until the chicken is cooked through and the breading is golden brown and crispy. Flip the nuggets halfway through the baking time to ensure even browning.
Optional: For a crispier texture, lightly spray the breaded nuggets with cooking oil before baking. Alternatively, the chicken can be marinated in buttermilk or yogurt for 30 minutes prior to breading for added tenderness and flavor.
