Instructions

  1. Step 1: Pat 4 white fish fillets dry and season both sides with 1 tsp salt and 1/2 tsp black pepper.
  2. Step 2: Heat 2 tbsp vegetable oil in a large skillet over medium-high heat. Add the fish and sear for 3-4 minutes per side until golden and cooked through. Remove and keep warm.
  3. Step 3: In the same skillet, add 1 tbsp vegetable oil and 1 large thinly sliced yellow onion. Sauté for 5 minutes until softened and translucent.
  4. Step 4: Add 3 minced garlic cloves, 1 small chopped scotch bonnet pepper, and 2 cups chopped tomatoes. Cook for 8 minutes until the tomatoes break down and the sauce thickens.
  5. Step 5: Stir in 2 tbsp chopped fresh parsley and 1 tbsp lemon juice, cooking for 1 more minute.
  6. Step 6: Spoon the tomato and onion sauce over the seared fish fillets and serve immediately with steamed rice or vegetables.

Frequently asked questions

How long does Pan-Seared Atlantic Fish with Senegalese Tomato and Onion Sauce take to make?

Total time is about 30 minutes (10 min prep + 20 min cook). Most home cooks find this fits comfortably into a weeknight; double the batch on Sunday for two dinners.

How do I store leftover Pan-Seared Atlantic Fish with Senegalese Tomato and Onion Sauce?

Refrigerate in a covered airtight container for up to 3–4 days (FDA FoodKeeper guideline for cooked fish). Store any fresh salsa or citrus-based garnish in a separate container — it keeps for up to 2 days. Freeze cooked fish (without fresh garnishes) for up to 3 months; thaw overnight in the fridge and reheat gently at 275°F until just warmed through to preserve texture.

Can I substitute ingredients in Pan-Seared Atlantic Fish with Senegalese Tomato and Onion Sauce?

Yes — most ingredients in this recipe have flexible swaps. For oil, use any neutral high-smoke-point oil (avocado, grapeseed, refined coconut). For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.

How do I scale Pan-Seared Atlantic Fish with Senegalese Tomato and Onion Sauce for a different number of people?

The recipe is written for 4 servings. Multiply each ingredient by (your serving target / 4). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.
