Ingredients

  • 16 plum tomatoes, halved lengthwise
  • 1/4 cup grated Parmesan cheese
  • 1 tablespoon dried oregano
  • 1 teaspoon sugar
  • 1 teaspoon salt
  • 1/2 teaspoon pepper
  • 2 tablespoons olive oil

Instructions

  1. Remove tomato seeds with a spoon.
  2. Place tomatoes, cut side up, on baking sheets coated with nonstick cooking spray.
  3. Sprinkle with cheese, oregano, sugar, salt, and pepper; drizzle with oil.
  4. Bake at 250°F (120°C) for 2 hours.

Tips & Substitutions

For the best flavor, choose ripe, firm plum tomatoes. If you prefer a different cheese, feta or goat cheese can be good substitutes for Parmesan. To enhance the dish, try adding fresh herbs like basil or thyme. Adjust the sugar based on the sweetness of your tomatoes; if they're very ripe, you may want to omit it. These slow-roasted tomatoes also make a great topping for grilled meats or as a component in Mediterranean recipes.

Serving Suggestions

Serve the slow-roasted tomatoes warm as a side dish or over a bed of pasta for a simple yet delicious meal. They also pair beautifully with grilled fish, such as Baked King Or Spanish Mackerel, or can be added to salads like Rice Salad Milano for extra flavor. For a light lunch, serve them on toasted bread or as part of a charcuterie board.

Storage & Reheating

Allow the roasted tomatoes to cool completely before transferring them to an airtight container. They can be stored in the refrigerator for up to a week. For longer storage, consider freezing them in a single layer on a baking sheet before moving them to a freezer-safe bag. To reheat, simply warm them in the oven or on a skillet over low heat until heated through.
