Additional Notes & Tips

  • Want extra flavor? Sauté the onions and garlic before adding them to the sauce.
  • Prefer a thicker sauce? Let the marinara simmer on the stove for 10 minutes before using.
  • No fresh basil? Use extra dried basil, and pretend you planned it that way.
  • Leftovers? Store in the fridge for 3 days or freeze for later.
