Set the oven to 300 degrees Fahrenheit.

Toss the tomatoes in a bowl with the olive oil, thyme, garlic, and red pepper flakes. Add salt and pepper to taste.

The tomato halves should be arranged cut-side up on a wire rack that has been fitted to a baking sheet. Cook the tomatoes for 1 1/2 to 2 hours, or until they are shriveled and soft.

serving recommendations: Slice the tomatoes roughly, then place them in a serving basin. Sprinkle with freshly grated Parmesan cheese and offer with crostini. Use as a topping for roasted chicken or fish, or add to pre-made tomato sauce to enhance flavor.
