Step 1

Thaw fish, if frozen. Cut fish into 3 x 2-inch pieces. Rinse fish; pat dry with paper towels. Cover and chill until needed.

Step 2

Preheat oven to 425°F. Line a large baking sheet with foil; lightly coat with nonstick cooking spray; set aside.

Step 3

For chips, pat potatoes dry with paper towels; place sweet potatoes in a large bowl. Add olive oil, Old Bay seasoning, 1/2 tsp. chili powder and 1/2 tsp. salt. Toss to coat. Arrange potatoes in a single layer on one half of the prepared baking sheet. Bake for 10 minutes.

Step 4

Meanwhile, for fish, place milk in a shallow dish. Place flour in another shallow dish. In a third shallow dish combine bread crumbs, 2 tsp. chili powder, paprika, 1/4 tsp. each salt and pepper. Add melted butter; stir until combined.

Step 5

Dip fish pieces in milk; coat with flour. Dip again in the milk, then in the bread crumb mixture. Remove baking sheet from oven. Using a spatula, carefully turn potatoes over. Place fish on the other half of the hot baking sheet; return to oven. Bake for 10 to 15 minutes more or until potatoes are golden brown and fish flakes easily with a fork. Serve fish with lemon wedges and fresh parsley, if desired.
