Ingredients

3 pounds ripe plum tomatoes, cut in half lengthwise
¼ cup plus 2 tablespoons good olive oil
1 tablespoon kosher salt
1½ teaspoons freshly ground black pepper
2 cups chopped yellow onions (2 onions)
6 garlic cloves, minced
2 tablespoons unsalted butter (substitute vegan)
¼ teaspoon crushed red pepper flakes
1 (28-ounce) canned plum tomatoes, with their juice
4 cups fresh basil leaves, packed
1 teaspoon fresh thyme leaves
1 quart unchicken broth or vegetable broth

Directions

Preheat the oven to 400 degrees F. Toss together the tomatoes, 1/4 cup olive oil, salt, and pepper. Spread the tomatoes in 1 layer on a baking sheet and roast for 45 minutes. In an 8-quart stockpot over medium heat, saute the onions and garlic with 2 tablespoons of olive oil, the butter, and red pepper flakes for 10 minutes, until the onions start to brown. Add the canned tomatoes, basil, thyme, and chicken stock. Add the oven-roasted tomatoes, including the liquid on the baking sheet. Bring to a boil and simmer uncovered for 40 minutes. Pass through a food mill fitted with the coarsest blade then puree in vitamix. Taste for seasonings. Serve hot or cold.

Note: I deglaze the pan with a little white wine before I add the tomatoes, basil thyme & stock.
