Recipe Overview

• Prep Time: 10 minutes
• Cook Time: 13 minutes
• Total Time: 23 minutes
• Servings: 4
• Dietary Type: Pescatarian, Gluten-Free

Ingredients

• 4 red snapper fillets or 4 perch fillets, skin on
• ½ cup fresh parsley, chopped
• 4 plum tomatoes, can use vine ripe, chopped
• 1 small onion, diced
• 2 ounces lemon juice
• Salt, to taste
• Pepper, to taste
• 2 tablespoons olive oil
• Canola oil, to coat baking dish

Equipment Needed

• Baking dish
• Medium saute pan
• Oven

Instructions

1. Preheat your oven to 325 degrees F (160 degrees C). This lower temperature allows the fish to cook gently and evenly, resulting in a moist and flaky texture.
2. Coat a baking dish thoroughly with canola oil. This step prevents the fish from sticking and helps the skin crisp up slightly during baking. Ensure the entire surface of the dish is coated to avoid any unwelcome surprises.
3. Place the fillets skin side down in the prepared baking dish. This ensures the skin gets the most direct heat, rendering the fat and creating a more flavorful result.
4. Pour the lemon juice evenly over the fish fillets. The acidity of the lemon juice not only adds a bright, tangy flavor but also helps to tenderize the fish.
5. Bake for approximately 8 minutes or less. The exact cooking time will depend on the thickness of your fillets. The fish is done when it flakes easily when touched with a fork. Be careful not to overcook, as this will result in dry fish. It’s always better to err on the side of slightly undercooked, as the residual heat will continue to cook it through.
6. While the fillets are baking, heat a medium saute pan over medium heat.
7. Add the olive oil to the heated saute pan. Allow the oil to heat up before adding the next ingredients to ensure they cook evenly.
8. Add the diced onion to the pan and saute until translucent. This usually takes about 3-5 minutes. Stir occasionally to prevent burning and ensure even cooking.
9. Once the onions are translucent, add the chopped plum tomatoes and fresh parsley to the pan.
10. Continue to saute for approximately 5 minutes over medium heat. This allows the tomatoes to break down slightly and release their juices, creating a delicious sauce. Stir occasionally to prevent sticking.
11. Remove the fillets from the oven.
12. Serve the baked fish immediately with the sauteed tomatoes and onions spooned generously on top. The contrast of the tender fish and the flavorful tomato topping is what makes this dish so delightful.

Expert Tips & Tricks

• For an extra layer of flavor, add a pinch of red pepper flakes to the tomato and onion mixture for a subtle kick.
• If you’re using frozen fish fillets, make sure to thaw them completely before cooking. Pat them dry with a paper towel to remove any excess moisture, which will help them bake more evenly.
• To prevent the fish from drying out during baking, you can tent the baking dish loosely with foil for the first half of the cooking time. Remove the foil for the last few minutes to allow the skin to crisp up.
• If you don’t have plum tomatoes on hand, you can substitute with canned diced tomatoes. Just make sure to drain them well before adding them to the pan.
• Don’t overcrowd the saute pan. If you have a lot of tomatoes and onions, cook them in batches to ensure they cook evenly.

Serving & Storage Suggestions

This Perch or Snapper Fillet with Tomatoes and Onion is best served immediately while the fish is still warm and the topping is vibrant. It pairs beautifully with a side of couscous, rice, or roasted vegetables. A crisp green salad with a light vinaigrette would also be a welcome addition.

Leftovers can be stored in an airtight container in the refrigerator for up to 2 days. To reheat, gently warm the fish and topping in a skillet over low heat or in the microwave. Be careful not to overcook the fish when reheating, as it can become dry. Reheating in the oven is also an option, but cover the dish with foil to prevent it from drying out.

While freezing is possible, the texture of the fish may be slightly compromised upon thawing.
