Instructions

  1. Step 1: In a bowl, mix 1 1/2 cups quartered cherry tomatoes, 1/3 cup thinly sliced fresh basil leaves, 1/4 cup finely diced red onion, 2 tbsp fresh lemon juice, 1 minced garlic clove, 1/2 tsp salt, and 1/4 tsp black pepper. Set aside to marinate while cooking the fish.

  5. Step 5: Remove fish from skillet and drizzle with remaining 1 tbsp olive oil. Serve topped generously with the prepared summer tomato and basil salsa.

Frequently asked questions

How do I store leftover Pan-Seared Sea Bass with Summer Tomato and Basil Salsa?

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.

How do I scale Pan-Seared Sea Bass with Summer Tomato and Basil Salsa for a different number of people?
