Step 1

If you are making your own marinara sauce, you'll need to do that first. In a medium saucepan or Dutch oven, add your San Marzano tomatoes, then add onions and garlic.

Step 2

Now add dried oregano, red pepper flakes, olive oil, and then stir to combine thoroughly. Bring the pan to a simmer over medium heat, then lower the heat, stir, and then leave to simmer for approximately 45 minutes

Step 3

Using the cooking instructions on your spaghetti packet, bring a large pan of salted water to a boil and then immerse the spaghetti into it. Stir to ensure the spaghetti doesn't stick together. When the spaghetti is cooked, transfer it to the cooked marinara sauce, if you get a little pasta water in the sauce then that's fine. Toss the spaghetti into the marinara sauce and ensure that it is fully coated. Serve in bowls, with a garnish of fresh basil leaves or a sprinkling of vegetarian or vegan Parmesan cheese

Step 4

Perfect pasta - enjoy!
