Instructions

  1. Step 1: Heat 1 tablespoon olive oil in a large skillet over medium-high heat. Add 1 minced garlic clove and cook for 60 seconds until fragrant, stirring constantly to prevent burning.
  2. Step 2: Arrange 12 oysters on the half shell in the skillet, cut side down, and cook for 2-3 minutes until the edges curl and the shells slightly open.
  3. Step 3: In a medium bowl, combine 1 cup diced heirloom tomatoes, 1/4 cup finely diced red onion, 2 tablespoons chopped basil, 1 tablespoon lemon juice, 1/4 teaspoon salt, 1/8 teaspoon black pepper, and a pinch of red pepper flakes. Toss to mix and set aside.
  4. Step 4: Transfer the oysters to a serving platter and spoon the heirloom tomato salsa over each oyster. Serve immediately.
