  • 2 lbs Roma tomatoes cut in half
  • 5 cloves garlic smashed
  • 1 medium yellow onion quartered
  • 1 carrot unpeeled and chopped into large pieces
  • 2 tsp kosher salt plus more to taste
  • 1 tsp ground black pepper plus more to taste
  • 2 tbsp olive oil
  • 3-4 basil leaves
  • 1/4 tsp dried thyme
  • 2 tbsp unsalted butter
  • 1/4 tsp sugar


  1. Preheat oven to 350 degrees.
  2. Line a baking sheet (with sides at least 1-inch deep) with parchment paper. Lay out the tomato halves (skin-side down), onion, garlic and carrot and sprinkle with salt, pepper and thyme. Try to make this only one layer to allow for maximum roasting. Drizzle olive oil all over.
  3. Bake for 60 - 75 minutes, or until the edges of the tomatoes and onions begin to turn black. Carefully transfer the roasted contents to a food processor or blender (or a large mixing bowl, if using a stick blender), add the basil leaves and pulse until smooth.
  4. Transfer the pureed contents to a large skillet and heat over medium-high heat. Add thyme, unsalted butter, sugar and more salt or pepper, to taste.
