Ingredients

Instructions

  1. Step 1: Preheat grill to medium heat (about 375°F). Pat dry 2 whole branzino fish and brush both sides with 3 tbsp olive oil. Season inside and out evenly with 1 1/2 tsp sea salt and 1 tsp black pepper.
  2. Step 2: Stuff each cavity with 3 lemon slices and 2 sprigs of fresh thyme to infuse flavor during grilling.
  3. Step 3: Place the fish on the grill and cook for 5-6 minutes per side, turning carefully once, until the skin is crisp and the flesh flakes easily with a fork.
  4. Step 4: Meanwhile, mix 4 tbsp softened unsalted butter with 2 minced garlic cloves and 2 tbsp chopped fresh parsley in a small bowl until combined.
  5. Step 5: Remove the grilled branzino from the grill and immediately spread the garlic herb butter inside the cavity and over the top of the fish while hot, allowing it to melt and soak into the flesh before serving.

How do I store leftover Whole Grilled Branzino with Lemon and Herb Butter?

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 olive oil from drying out.

Can I substitute ingredients in Whole Grilled Branzino with Lemon and Herb Butter?

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 Whole Grilled Branzino with Lemon and Herb Butter 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.
