Gather Your Ingredients
Start with simple pantry staples: San Marzano tomatoes, onions, garlic, dried oregano, red pepper flakes, olive oil, and spaghetti. Fresh basil and Parmesan are optional but recommended!
Stir in dried oregano and red pepper flakes for a touch of spice, then drizzle in olive oil. Bring to a simmer over medium heat, then reduce to low and let it bubble gently.
