2 Cups chopped yellow onions (about 2 small onions or 1 large)
6 Garlic cloves, minced
28 ounce can of plum tomatoes with liquid
4 cups of fresh basil leaves, packed
1 Teaspoon of fresh (or dried) thyme leaves
1 Quart of chicken or vegetable stock
Sea salt and pepper to taste
Optional: 1/4 of crushed red pepper flakes if desired
Preheat oven to 400 degrees. Toss together the fresh tomatoes and 1/4 olive oil. Spread the tomatoes in 1 layer on a baking sheet and roast for 45 minutes.
In an 8-quart stockpot over medium heat, sauté the onions, garlic and red pepper flakes for 10 minutes until the onions start to brown. Add the canned tomatoes, basil, thyme, and chicken (or vegetable) stock. Add the oven-roasted tomatoes including the liquid on the baking sheet. Bring to a boil and simmer uncovered for 40 minutes.
Use a hand blender to blend thoroughly. Add sea salt and pepper to taste. Garnish with a basil leaf or a sprinkle of chopped basil.
