Ingredients

  • 3 lb Roma tomatoes (about 9 large)
  • 1 small onion (cut into ½ inch chunks)
  • 4-6 cloves or 1 tablespoon minced
  • 2 tablespoons olive oil
  • 1 teaspoon salt
  • ¼ teaspoon pepper
  • 3 tablespoons fresh basil
  • 2 tablespoons tomato paste
  • 1 teaspoon sugar
  • salt and pepper to taste

Instructions

  • Preheat oven to 400 degrees F.
  • Halve tomatoes and place cut side up with the onion and garlic on a lightly greased rimmed baking sheet. Drizzle with oil and sprinkle with salt and pepper. Stir to coat well.
  • Roast for 40-50 minutes, just until starting to brown.
  • Scrape everything into the blender (if you prefer, you can pull the peel off the tomatoes first) and add the basil, tomato paste, and sugar. Puree until completely smooth and adjust seasonings to taste.
  • OPTIONAL: you can add cream and/or Parmesan for a richer, creamier flavor.

Notes

Ingredients and Substitutions:
  • Tomatoes: I love using Roma tomatoes for this recipe because they are flavorful and not very watery. Cherry or grape tomatoes are also delicious!
  • Vegetables: feel free to add additional vegetables to your roasting pan: carrots and celery would work well, too!
  • Herbs: basil is an obvious choice but other fresh herbs work well, too: try dill, parsley or thyme (pull it off the stem). You can also sub the fresh basil for a teaspoon of dried basil or basil pesto.
  • Seasonings: make it a spicy tomato sauce by adding a pinch of cayenne or red pepper flakes. 
  • Cream: a bit of cream or evaporated milk can take this simple, fresh sauce to a luxurious level. 
  • Parmesan: Parmesan adds a delicious salty and cheesy flavor -- feel free to add some in if you have it!
