Ingredients

Instructions

  1. Step 1: Core and chop 24 oz tomatoes into 1-inch pieces. Finely chop 1/2 cup onion and mince 4 garlic cloves. Place in a large pot with 2 tbsp olive oil and sauté over medium heat for 8 minutes until onions are translucent and garlic is fragrant.
  2. Step 2: Add tomatoes to the pot, breaking them with a spoon. Bring to a simmer, then reduce heat to low. Cover and cook for 25 minutes, stirring occasionally.
  3. Step 3: While soup simmers, spiralize 2 medium zucchini into noodles. Pat dry with a clean towel to remove excess moisture.
  4. Step 4: Stir 1/4 cup fresh basil into the simmering soup and cook for 2 more minutes. Divide soup into bowls, top with 1 cup zucchini noodles per serving, and serve immediately.
