Begin by cutting the chicken breasts into strips, then season them with garlic salt and dried parsley.
Beat the egg in a shallow bowl.
Dip each chicken strip into the beaten egg, ensuring it's thoroughly coated.
Next, spread the crushed cornflakes onto a plate. Coat each egg-dipped chicken strip with the crushed cornflakes, pressing gently to adhere. (To maintain crispiness, add the cornflakes to the plate gradually as needed.)
Preheat the oven to 400 degrees Fahrenheit.
Place the coated chicken strips in the oven, ensuring they're not overcrowded.
Bake the chicken for 15-18 minutes.
While the chicken cooks, prepare the garlic Parmesan topping. Melt the butter in a small saucepan over low heat. Crush the garlic cloves and add them to the melted butter, along with the chopped parsley and chili flakes. Stir until fragrant and well combined.
Once the chicken is cooked through and crispy, either drizzle the garlic mixture over the top or brush it onto the chicken using a pastry brush or spoon.
Finally, generously sprinkle grated Parmesan cheese over both sides of the chicken strips.
Serve immediately and enjoy the delicious garlic Parmesan chicken tenders!
