Ingredients

Scale
  • 2 tablespoons extra virgin olive oil
  • 1 medium onion, finely chopped
  • 3 cloves garlic, minced
  • 1 (28-ounce) can crushed tomatoes
  • 1 (6-ounce) can tomato paste
  • 1 medium carrot, peeled and chopped
  • 1 small zucchini, chopped
  • 1 cup spinach leaves, packed
  • ½ cup red bell pepper, chopped
  • 1 teaspoon dried oregano
  • 1 teaspoon dried basil
  • ½ teaspoon red pepper flakes (optional)
  • 1 tablespoon balsamic vinegar
  • Salt and freshly ground black pepper, to taste
  • 1 teaspoon sugar or honey (optional)

Instructions

  1. Peel and chop the carrot, zucchini, bell pepper, and wash the spinach. Rough chop is fine since you’ll puree them. (Prep time: 10 minutes)
  2. Heat 2 tablespoons olive oil in a large sauté pan over medium heat. Add the chopped onion and sauté until translucent, about 5 minutes. Stir in minced garlic and cook for another 1 minute until fragrant, being careful not to burn the garlic.
  3. Place carrot, zucchini, spinach, and bell pepper into a blender or food processor. Add 2-3 tablespoons of water to help blend into a smooth puree. Add more water a teaspoon at a time if needed for smooth texture.
  4. Stir the crushed tomatoes and tomato paste into the pan with onions and garlic, mixing well.
  5. Pour the pureed vegetables into the tomato mixture and stir thoroughly. The sauce will thicken as it simmers.
  6. Add oregano, basil, red pepper flakes (if using), balsamic vinegar, salt, pepper, and sugar or honey. Stir to combine and bring the sauce to a low simmer.
  7. Reduce heat to low and let the sauce simmer uncovered for 25-30 minutes, stirring occasionally. Add a splash of water or broth if the sauce becomes too thick.
  8. Taste the sauce and adjust salt, pepper, or sweetness as needed before serving.

Notes

Puree the veggies completely for a smooth sauce texture. Avoid burning garlic by cooking on moderate heat. Simmer uncovered to thicken and concentrate flavors. Adjust seasoning gradually and taste as you go. The sauce freezes well for up to 3 months in airtight containers. For a meaty version, brown ground turkey or beef before adding onions. For dairy-free creaminess, stir in coconut cream at the end.
