Memorial Day weekend is almost here. This week, we'll offer recipes perfect for a holiday cookout. This recipe comes from the vault of Martha Stewart.
3 lbs. ground chuck
1 1/2 teaspoons freshly ground pepper
3 oz. thinly sliced fresh mozzarella, optional
1 tablespoon chopped fresh herb leaves, such as oregano or basil (optional)
12 grape tomatoes, halved (optional)
Vegetable oil, for brushing
6 hamburger buns, such as sesame
Using your hands, combine beef, 3 teaspoons salt, and the pepper in a bowl. Shape into 6 balls. Scoop a heaping tablespoon from center of each; reserve.
Fill each burger with 1/2 ounce mozzarella, 1/2teaspoon herbs, and 4 tomato halves; season with salt.
Press the reserved meat over filling, pinching to seal. Gently flatten into patties (about 5 inches in diameter). Refrigerate, covered, until cold, about 1 hour.
Preheat grill to medium-high (if using a charcoal grill, coals are ready when you can hold your hand 5 inches above grill for just 3 to 4 seconds). Brush grill and burgers with oil. Grill, flipping once, about 4 minutes per side for rare or 10 minutes per side for well- done. Toast buns, if desired. Serve burgers on buns.
