Full Ingredients
For the Burger Patties
- 1 pound 93% lean ground beef, cold
- 3/4 teaspoon kosher salt
- 1/2 teaspoon freshly ground black pepper
- 1 teaspoon Italian seasoning
- 1 teaspoon garlic powder
- 1 tablespoon olive oil, for brushing the grill grates or coating the skillet
For the Caprese Toppings

- 1 large ripe tomato, cut into 4 thick slices
- 1/4 teaspoon kosher salt, for the tomato
- 2 cups baby arugula, lightly packed
- 1 teaspoon fresh lemon juice
- 1/2 cup basil pesto, homemade or store-bought
- 1/4 cup balsamic glaze
For Serving
- 4 whole-wheat burger buns, split
- 1 teaspoon olive oil or softened butter, optional, for toasting buns
Optional Quick Homemade Basil Pesto
- 2 packed cups fresh basil leaves
- 1/4 cup grated Parmesan cheese
- 3 tablespoons pine nuts or walnuts
- 1 small garlic clove
- 1 tablespoon fresh lemon juice
- 1/4 teaspoon kosher salt
- 1/3 cup extra-virgin olive oil
Step-by-Step Instructions
Step 1: Prepare the pesto if making it from scratch
If using store-bought pesto, skip to Step 2. To make the optional quick homemade basil pesto, add the basil, Parmesan, pine nuts or walnuts, garlic, lemon juice, and 1/4 teaspoon kosher salt to a food processor. Pulse until finely chopped. With the machine running, drizzle in 1/3 cup extra-virgin olive oil and blend until the pesto is spoonable but still slightly textured. Taste and adjust with a small pinch of salt if needed.
Step 2: Season the toppings
Slice the fresh mozzarella into 4 even pieces and set them on a plate. Slice the tomato into 4 thick rounds, then sprinkle the tomato slices with 1/4 teaspoon kosher salt. This simple seasoning wakes up the tomato and gives the burger a more balanced Caprese flavor. In a small bowl, toss the baby arugula with 1 teaspoon fresh lemon juice. Keep the balsamic glaze nearby for assembly.
Step 3: Shape the burger patties
Place the cold ground beef in a mixing bowl. Sprinkle with 3/4 teaspoon kosher salt, black pepper, Italian seasoning, and garlic powder. Use clean hands or a fork to gently mix just until the seasonings are distributed. Avoid overmixing, which can make the burgers dense.
Divide the mixture into 4 equal portions, about 4 ounces each. Shape each portion into a patty about 3/4 inch thick and slightly wider than the buns, since the patties will shrink as they cook. Press a shallow dimple into the center of each patty with your thumb; this helps the burgers cook evenly and stay flatter.
Step 4: Preheat the cooking surface
Preheat an outdoor grill, grill pan, or large cast-iron skillet over medium-high heat until it reaches about 400°F. If using a skillet, heat it for 3 to 4 minutes before adding the burgers. Brush the grill grates or skillet with 1 tablespoon olive oil to help prevent sticking and encourage good browning.
Step 5: Cook the burgers
Place the patties on the hot grill or skillet. Cook undisturbed for 4 to 5 minutes on the first side, until the bottoms are well browned and release easily. Flip the burgers and cook for 3 to 4 minutes more.
During the last 1 to 2 minutes of cooking, place 1 slice of fresh mozzarella on each patty. Cover the grill or loosely tent the skillet with foil to help the mozzarella soften. Cook until the cheese is gently melted and the center of each burger reaches 160°F on an instant-read thermometer.
Step 6: Toast the buns
While the burgers finish cooking, toast the split buns. For a grill or grill pan, place the buns cut-side down for 1 to 2 minutes, just until lightly golden. For a skillet, add 1 teaspoon olive oil or softened butter if desired, then toast the buns cut-side down for 1 to 2 minutes. Toasting helps the buns hold up to the juicy tomato, pesto, and balsamic glaze.
Step 7: Rest the burgers briefly
Transfer the cooked burgers to a clean plate and let them rest for 3 minutes. This short rest keeps the patties juicy and allows the melted mozzarella to settle into the top of each burger.
Step 8: Assemble the Caprese burgers
Spread about 1 tablespoon basil pesto on the cut side of each bottom bun and another 1 tablespoon on the cut side of each top bun, using 2 tablespoons pesto total per burger. Add a small handful of lemon-dressed baby arugula to each bottom bun. Place a mozzarella-topped burger patty over the arugula, then add a seasoned tomato slice. Drizzle each burger with 1 tablespoon balsamic glaze. Finish with the top bun and serve right away while the burgers are warm, the mozzarella is soft, and the greens are fresh.
Pro Tips
- Use ripe tomatoes: Since tomato is a major flavor in a Caprese-style burger, choose a ripe, juicy tomato that smells sweet and feels heavy for its size.
- Do not overwork the meat: Mix the seasonings in gently and stop as soon as everything is combined. This keeps the patties tender.
- Watch the balsamic glaze: A little goes a long way. Use about 1 tablespoon per burger so the sweetness complements the pesto without overpowering it.
- Keep pesto off direct heat: Add pesto after cooking so the basil stays bright green and fresh-tasting.
- Use a thermometer: For the best texture and food safety, cook ground beef burgers to an internal temperature of 160°F.
Variations
- Turkey Caprese Burger: Replace the ground beef with 1 pound 93% lean ground turkey. Add 1 tablespoon grated Parmesan to the patty mixture for extra flavor and cook to 165°F.
- Chicken Caprese Burger: Use 1 pound ground chicken and add 2 tablespoons finely chopped basil to the patties. Cook to 165°F and assemble the same way.
- Low-carb Caprese Burger Bowl: Skip the bun and serve the mozzarella-topped patty over a bed of arugula with tomato, pesto, and balsamic glaze drizzled over the top.
Storage & Make-Ahead
For best results, store the cooked burger patties separately from the buns and fresh toppings. Refrigerate cooked patties in an airtight container for up to 3 days. Reheat in a covered skillet over medium-low heat for 4 to 6 minutes, or until warmed through to 165°F. The pesto can be made up to 3 days ahead and refrigerated in a sealed container; press a thin layer of olive oil or plastic wrap directly onto the surface to help keep it green. Tomato slices and arugula are best prepared the day you serve. Assemble the burgers just before eating so the buns stay toasted and the arugula stays crisp.
