Ingredients

Instructions

  1. Step 1: Pat the 12 oz walleye fillets dry with paper towels and season evenly with 1/2 tsp salt and 1/4 tsp black pepper on both sides.
  2. Step 2: Heat 1 tbsp olive oil in a large skillet over medium-high heat until shimmering. Add the walleye fillets skin-side down and cook for 4-5 minutes without moving until golden brown.
  3. Step 3: Flip the fillets and cook for an additional 3-4 minutes until the fish is opaque and flakes easily with a fork.
  4. Step 4: Remove the fish from the skillet and set aside. Add the remaining 1 tbsp olive oil to the skillet and add the 1 medium thinly sliced yellow onion. Sauté over medium heat for 8-10 minutes until the onions are deeply golden and crispy.
  5. Step 5: Return the fish to the skillet and gently toss with the onions for 1 minute to coat. Serve immediately with 1/2 lemon cut into wedges and 1 tbsp chopped fresh parsley.
