Ingredients

  • 2 pounds roma tomatoes
  • 1 sweet onion peeled and quartered
  • 2 tablespoons olive oil
  • 4 tablespoons balsamic vinegar divided
  • 1 whole head garlic
  • ¼ cup fresh basil leaves lightly packed
  • Kosher salt
  • Black pepper

Instructions

  • Preheat your oven to 425 degrees F and line a large baking sheet with foil. It will help keep the tomatoes from sticking to the pan.
  • Add the tomatoes and onion to the pan and drizzle over 1.5 tablespoons of olive oil along with the balsamic vinegar.
  • Sprinkle generously with salt and pepper and toss to combine. 
  • Slice the top off the head of garlic, making sure to leave it intact.
  • Drizzle the remaining half tablespoon of olive oil over the garlic and wrap it tightly in foil. Place the garlic cut side up on the baking sheet. 
  • Roast for 35 minutes, or until the tomatoes are caramelized and the onions are golden brown. 
  • Remove the garlic from the foil and squeeze out the cloves. Be careful, it will be hot! 
  • Add the garlic cloves to a food processor, along with the roasted tomatoes, roasted onion, remaining two tablespoons of balsamic vinegar, and fresh basil.
  • Puree to your desired consistency and season with salt and pepper to taste. 
  • Store the marinara sauce in an airtight container in the fridge for up to five days or in an airtight container in the freezer for up to three months.
