Why You’ll Love This Recipe

This recipe is incredibly simple yet packed with flavor. It takes only minutes to prepare and uses pantry-friendly ingredients with no need for eggs, breadcrumbs, or frying oil. The salt and vinegar potato chips form a crisp, tangy coating that pairs perfectly with the delicate, flaky texture of white fish. Whether you're cooking sea bass, grouper, or any other mild white fish, this dish is a guaranteed crowd-pleaser.

Ingredients

(Tip: You'll find the full list of ingredients and measurements in the recipe card below.)

sea bass or grouper fillets (4 to 5 ounces each)
low-fat mayonnaise
salt and vinegar potato chips
salt
pepper

Directions

Preheat the oven to 400°F (204°C). Line a rimmed baking sheet with parchment paper.

Pat the fish fillets dry with a paper towel and place them skin-side down on the parchment.
Brush the top of each fillet with a thin layer of mayonnaise.
Season lightly with salt and pepper.
Crush the potato chips until fine using a food processor or by placing them in a zip-top bag and crushing with a rolling pin. Pour the crumbs onto a plate.

Press the top of each fillet into the crushed chips, coating well. Place the fish back on the parchment with the chip-coated side facing up.
Bake for 10–15 minutes depending on the thickness of your fish. Thinner fillets (about 1 inch thick) may only need 10 minutes, while thicker ones (closer to 2 inches) may need up to 15 minutes.
Remove from the oven when the fish flakes easily with a fork and is still slightly soft in the center.

Serve immediately while hot and crispy.

Storage/Reheating

To store: Place any leftovers in an airtight container and refrigerate for 2–3 days.
