Prep and Cook Time
- Preparation Time: 15 minutes
- Roasting Time: 4 hours
- Total Time: 4 hours 15 minutes
Yield
Approximately 3 cups of slow-roasted tomatoes, serving 6 as a flavorful condiment or side
Difficulty Level
Easy – perfect for home cooks seeking an effortless, yet remarkable flavor boost
Ingredients
- 2 pounds ripe Roma tomatoes, halved lengthwise
- 1/3 cup extra virgin olive oil (choose a fruity or peppery variety for depth)
- 4 cloves garlic, thinly sliced
- 1 teaspoon sea salt
- 1/2 teaspoon freshly ground black pepper
- 1 tablespoon fresh thyme leaves
- 1 cup fresh basil leaves, torn, for garnish
- 1 teaspoon crushed red pepper flakes (optional for warmth)
Instructions
- Preheat your oven to 225°F (105°C). Using a low-and-slow heat method ensures the tomatoes develop a luxuriously sweet and savory profile without burning.
- Prepare the tomatoes: Place the halved tomatoes cut-side up on a rimmed baking sheet lined with parchment paper. Arrange them close, but not touching.
- Drizzle liberally with the extra virgin olive oil, ensuring each tomato half is generously coated to enhance caramelization and prevent drying.
- Sprinkle the garlic slices, fresh thyme, sea salt, black pepper, and, if using, red pepper flakes evenly over the tomatoes. These aromatics intensify the flavor layers while roasting.
- Roast uncovered in the oven for about 4 hours, or until tomatoes are shriveled, tender, and jammy, with edges slightly caramelized but not burnt. Rotate the tray halfway through for even cooking.
- Remove from the oven and allow the tomatoes to cool slightly. Taste and adjust seasoning if necessary.
- Garnish with the torn fresh basil leaves just before serving to add a fresh herbal brightness that contrasts beautifully with the concentrated tomato essence.
- Serve warm or at room temperature,spooned over crostini,stirred into pasta,or atop roasted meats for a gourmet finish.
Tips for Success
- Choosing tomatoes: Select firm, ripe Roma or plum tomatoes-they have fewer seeds and thicker flesh that roasts beautifully.
- Olive oil matters: Use a high-quality extra virgin olive oil with robust flavor. A peppery or fruity variation gives an extra punch that enhances the slow-roasted tomatoes beautifully.
- Flavor variations: Swap thyme for oregano or rosemary for a different herbaceous layer, or add a splash of balsamic vinegar before roasting for sweetness and tang.
- Storage: Refrigerate the cooled tomatoes in an airtight container for up to 5 days or freeze portions in ice cube trays to preserve flavor for later recipes.
- Make-ahead: Slow-roasted tomatoes can be prepared days in advance, making them an ideal choice for entertaining or meal prep without sacrificing freshness.
Serving Suggestions
- Serve spooned atop creamy burrata or fresh mozzarella drizzled with balsamic glaze for a spectacular appetizer.
- Mix into freshly cooked pasta with a handful of Parmesan shavings and a drizzle of olive oil for an easy weeknight meal.
- Use as a vibrant topping for grilled chicken or fish to add layers of flavor and color.
- Layer inside toasted baguette slices with goat cheese and arugula for a gourmet open-faced sandwich.
- Garnish with microgreens, toasted pine nuts, or a sprinkle of flaky sea salt for added texture and luxury.
