Ingredients

Instructions

  1. Step 1: Preheat oven to 400°F (200°C). Toss 2 cups halved cherry tomatoes with 2 tbsp extra virgin olive oil, 1 minced garlic clove, 1/2 tsp salt, and 1/4 tsp black pepper on a rimmed baking sheet. Roast for 15 minutes until tomatoes are soft and slightly caramelized.
  2. Step 2: Meanwhile, pat dry 4 sea bass fillets and season both sides with 1/2 tsp salt and 1/4 tsp black pepper. Heat 2 tbsp extra virgin olive oil in a large nonstick skillet over medium-high heat.
  3. Step 3: Place sea bass fillets skin side down in the skillet and cook for 4-5 minutes until the skin is crisp and golden. Flip and cook for an additional 2-3 minutes until fish is opaque and flakes easily.
  4. Step 4: Remove fish from heat and drizzle with 2 tbsp fresh lemon juice. Plate the fillets and spoon the roasted cherry tomatoes over the top.
  5. Step 5: Sprinkle 1/4 cup chopped fresh basil over the dish and serve immediately for a fresh and vibrant Mediterranean meal.

Frequently asked questions

How long does Pan-Seared Sea Bass with Roasted Cherry Tomatoes and Basil take to make?

How do I store leftover Pan-Seared Sea Bass with Roasted Cherry Tomatoes and Basil?

Cool to room temperature within 2 hours, then store in an airtight container in the fridge for up to 4 days. Reheat covered in a 350°F oven for 10-12 minutes, or microwave at 70% power in 60-second bursts to keep halved cherry tomatoes from drying out.

Can I substitute ingredients in Pan-Seared Sea Bass with Roasted Cherry Tomatoes and Basil?

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 Sea Bass with Roasted Cherry Tomatoes and Basil 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.
