Instructions

  1. Step 1: Preheat oven to 425°F. Toss 1 sliced medium zucchini, 1 large chopped red bell pepper, and 1 quartered medium red onion with 2 tbsp extra virgin olive oil, 1 tsp dried oregano, 1/2 tsp salt, and 1/4 tsp black pepper. Spread evenly on a baking sheet and roast for 20 minutes until tender and caramelized.
  2. Step 2: While vegetables roast, pat dry 4 sea bass fillets and season both sides with 1 tsp salt and 1/2 tsp black pepper.
  3. Step 3: Heat 1 tbsp olive oil in a large nonstick skillet over medium-high heat. Add sea bass fillets skin-side down and cook for 4-5 minutes until skin is crisp and golden. Flip fillets and cook an additional 2-3 minutes until fish is opaque and flakes easily.
  4. Step 4: Remove fish from skillet and set aside. Lower heat to medium and add 4 tbsp butter, 2 tbsp drained capers, 2 tbsp fresh lemon juice, and 1 minced garlic clove to the skillet. Stir until butter melts and sauce thickens slightly, about 2 minutes.
  5. Step 5: Plate roasted vegetables, top with sea bass fillets, and spoon caper-lemon butter sauce over the fish immediately before serving.

Frequently asked questions

How long does Pan-Seared Sea Bass with Caper-Lemon Butter and Roasted Vegetables take to make?

How do I store leftover Pan-Seared Sea Bass with Caper-Lemon Butter and Roasted Vegetables?

Refrigerate in a covered airtight container for up to 3–4 days (FDA FoodKeeper guideline for cooked fish).

Can I substitute ingredients in Pan-Seared Sea Bass with Caper-Lemon Butter and Roasted Vegetables?

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 Caper-Lemon Butter and Roasted Vegetables for a different number of people?
