Pat the fish fillets dry with a paper towel. Cut them into manageable-sized pieces if needed.

In a mixing bowl, combine Bisquick mix, egg, beer, and golden cornmeal. Mix until you achieve a smooth batter. Adjust the consistency by adding more beer or Bisquick if necessary.

Season the batter with sun-dried salt and freshly ground pepper. Mix well to incorporate the seasoning.

In a deep fryer or large, deep pan, heat oil to 375°F (190°C). Use enough oil to submerge the fish pieces.

Dip each fish fillet into the Bisquick beer batter, ensuring it is thoroughly coated.

Carefully place the battered fish into the hot oil. Fry until the exterior is golden brown and the fish is cooked through, approximately 3-5 minutes per side depending on thickness.

Use a slotted spoon to remove the fried fish from the oil. Place them on a plate lined with paper towels to drain excess oil.

While the fish is frying, mix up your favorite tartar sauce or use store-bought.

Serve the crispy Bisquick beer-battered fish hot with a side of tartar sauce.

Garnish with fresh lemon wedges and parsley for a burst of flavor.

Enjoy your delicious Bisquick beer-battered fish, a simple and flavorful dish that's perfect for any occasion!
