Grilled Tomatoes and Oregano

Category: Perfect Side Dishes

Juicy, semi-firm tomatoes are halved, marinated in olive oil, balsamic vinegar, garlic, oregano, salt, and pepper, then grilled until softened with deep, flavorful grill marks. These are finished with extra herbs, a drizzle of olive oil, and a sprinkle of salt for enhanced taste. This vibrant preparation can be served warm or at room temperature, offering a naturally smoky-sweet profile that pairs beautifully with a variety of dishes. Any leftovers are delicious cold or repurposed into salads, soups, or sauces, making this a versatile addition to summer meals.

Sweet juicy tomatoes charred on a hot grill and finished with good olive oil and fresh oregano have become my favorite summertime side for almost any meal. Every time I make grilled tomatoes this way, I’m reminded how simple produce can taste absolutely luxurious with the right treatment and a quick marinade.

The night I first grilled tomatoes outside during a backyard pizza party, people kept wandering over to ask what smelled so good. Now every summer gathering starts with a big platter of these.

Ingredients

  • Tomatoes: Choose semi firm tomatoes like Roma or heirloom for best grilling results Soft ones will tend to collapse Veggie stands and local markets are perfect for fresh picks
  • Olive oil: Use a fruity extra virgin for richer taste A drizzle at the end adds even more flavor Check the harvest date for peak freshness
  • Balsamic vinegar: Brings a tangy sweetness that balances the char Choose a syrupy aged variety if you can
  • Garlic: Fresh cloves add punch Finely mince for even distribution in the marinade
  • Fresh oregano: Chopped leaves bring classic Mediterranean aroma Use only the freshest sprigs for bold flavor
  • Salt: Essential for bringing out the tomato flavor Flakey finishing salt is especially delicious sprinkled on right before serving
  • Pepper: Freshly cracked black pepper adds a bit of contrast and spice

I adore the scent of oregano as it hits the hot tomatoes It always reminds me of my grandmother’s kitchen where herbs hung drying over the windowsill She would say the simplest dishes are the best

Storage Tips

Grilled tomatoes keep well for up to four days in the refrigerator Store them in a covered dish or airtight container They taste fantastic straight from the fridge or brought back to room temperature They are also a wonderful addition to salads pasta or turned into a quick rustic sauce for grains

Ingredient Substitutions

Instead of balsamic vinegar you can use red wine vinegar with a splash of honey for sweetness If you do not have fresh oregano try using thyme or basil Fresh herbs always offer the brightest flavor but in a pinch a small amount of dried oregano works Just use a little less

Serving Suggestions

Pile these tomatoes over crostini topped with a little ricotta cheese or serve alongside grilled meats and seafood If you have leftovers chop them up for bruschetta or blend with fresh basil for a fast pasta topping They also pair well with creamy burrata or scattered over grain bowls

Yield: 6 Servings (6 whole grilled tomatoes)

Dietary Preferences: Vegan, Vegetarian, Gluten-Free, Dairy-Free

Ingredients

→ Vegetables

01 900 g semi-firm tomatoes (such as Roma, Vine ripened, Better Boy, or Heirloom), 7–13 cm in diameter

→ Marinade

02 2 tablespoons extra virgin olive oil, plus more for finishing
03 2 tablespoons balsamic vinegar
04 2–4 garlic cloves, finely minced
05 2–3 tablespoons fresh oregano, chopped
06 0.5 teaspoon fine salt, plus more for finishing
07 1 teaspoon freshly ground black pepper

Steps

Step 01

Preheat the grill to medium-high. Clean and oil the grate well. With a sharp knife, core the tomatoes and slice each in half. If using Roma tomatoes, cut through the core; for round varieties, slice perpendicular to the core.

Step 02

Place tomatoes in a mixing bowl. In a separate bowl, mix olive oil, balsamic vinegar, minced garlic, chopped oregano, salt, and pepper. Pour marinade over tomatoes and gently toss to coat evenly.

Step 03

Place tomatoes cut side down on the greased grill, reserving any remaining marinade. Cover and grill for 5–7 minutes (longer for larger tomatoes) until deep char marks form. Using a thin metal spatula, turn tomatoes and continue grilling, covered, until just softened but still intact.

Step 04

Transfer grilled tomatoes to a serving platter. Spoon reserved marinade over the top, distributing oregano evenly. Drizzle with additional olive oil and sprinkle with finishing salt as desired. Serve warm or at room temperature.

Notes

  1. Semi-firm tomatoes maintain structure best on the grill, preventing collapse during cooking.
  2. A grill pan on the stovetop is an effective alternative to outdoor grilling.
  3. Grilled tomatoes can be refrigerated for up to 4 days and enjoyed cold, or incorporated into salads, soups, bruschetta, or sauces.
