Ingredients

• 2 pounds ripe plum or Roma tomatoes
• 6 pieces garlic cloves
• 1 medium yellow onion
• 3 tablespoons extra virgin olive oil
• 6 pieces fresh basil leaves
• 4 pieces fresh thyme sprigs
• 1 teaspoon sea salt
• 0.5 teaspoon black pepper
• 0.25 teaspoon red pepper flakes (optional)
• 1 teaspoon balsamic vinegar (optional)

Directions

Step 1

Preheat your oven to 400°F (200°C).

Step 2

Wash and dry the tomatoes, then cut them in half lengthwise and place them cut-side up on a large baking sheet.

Step 3

Peel the garlic cloves, leaving them whole. Slice the yellow onion into thick wedges.

Step 4

Distribute the garlic cloves and onion wedges evenly around the tomatoes on the baking sheet.

Step 5

Drizzle the tomatoes, garlic, and onions with the olive oil, ensuring everything is evenly coated.

Step 6

Sprinkle the sea salt, black pepper, and red pepper flakes (if using) over the vegetables.

Step 7

Tuck the fresh basil leaves and thyme sprigs among the vegetables for added aroma and flavor.

Step 8

Place the baking sheet in the preheated oven and roast for 40-45 minutes, or until the tomatoes are soft, lightly caramelized, and slightly shriveled.

Step 9

Remove the baking sheet from the oven and let the vegetables cool for 5-10 minutes.

Step 10

Transfer the roasted tomatoes, garlic, onions, and any accumulated juices from the baking sheet into a blender or food processor.

Step 11

Add the balsamic vinegar (if using) for added depth of flavor, and blend until the sauce reaches your desired consistency. For a smoother texture, blend longer; for a chunkier sauce, pulse lightly.

Step 12

Taste the sauce and adjust seasoning with additional salt and pepper, if needed.

Step 13

Serve immediately over pasta, as a pizza base, or store in an airtight container in the refrigerator for up to 5 days or freeze for up to 3 months.
