First, preheat your oven to 425°F (220°C). This temperature is crucial for that lovely crispy exterior we all crave.

Line a baking sheet (11x17 inches) with aluminum foil. This will aid in easy cleanup later. Lightly spray the foil with cooking spray to ensure the tilapia doesn’t stick.

In a shallow bowl, combine the milk and ranch dressing. Give it a good whisk until everything is blended together. This creamy mixture will help the breadcrumbs stick to the fish later.

In another shallow bowl, pour the all-purpose flour. This step helps create a barrier that keeps the fish from becoming soggy and aids in achieving that crispy texture.

In a medium-sized bowl, combine the dry breadcrumbs, grated Parmesan cheese, seasoned salt, black pepper, celery salt, garlic powder, onion powder, paprika, parsley, and basil. These ingredients will infuse the breading with flavor.

Using cooking spray, lightly mist the breadcrumb mixture until it’s slightly damp. Stir the mixture well to ensure it’s evenly moist. This step helps the crumbs crisp up nicely in the oven.

Move the breadcrumb mixture to a large resealable plastic bag. This will make the coating process much easier and less messy.

Start by gently pressing each tilapia fillet into the flour, coating it evenly. Make sure to shake off any excess flour so it doesn’t clump. Dip the floured fillet into the ranch mixture, allowing any dripping to fall away before placing the fillet in the plastic bag with the bread crumbs.

Seal the bag and shake it gently to coat the fish with the breadcrumb mixture evenly. You can do this in batches if needed.

Carefully arrange the coated tilapia fillets on the prepared baking sheet. Once they are laid out, give them a light spray with cooking spray to ensure even browning.

Pop the baking sheet into your preheated oven and bake for about 20 to 25 minutes. You’re looking for the fish to be flaky and easy to break apart with a fork.
