Steps

  1. Prepare aromatics and basil. Prepare the diced yellow onion, minced garlic, and chopped fresh basil before heating the pot.
    • 1 cup yellow onion — diced
    • 1 tablespoon garlic — minced
    • 1/2 cup basil — chopped

    Keep the knife blade angled away from fingers while chopping.

  2. Sauté the onion. Heat the olive oil in the large pot over medium heat, then add the onion and cook for 3 to 4 minutes until softened and lightly translucent.
    • 2 tablespoons olive oil
    • 1 cup yellow onion — diced

    Use caution with hot oil and keep the pot handle turned inward on the stovetop.

  3. Bloom garlic and pepper flakes. Add the garlic and red pepper flakes, then cook for 30 seconds until fragrant.
    • 1 tablespoon garlic — minced
    • 1/4 teaspoon red pepper flakes
  4. Build the tomato broth. Add the crushed tomatoes, vegetable broth, salt, and black pepper, then stir well and bring to a steady simmer.
    • 2 cups tomatoes
    • 4 cups vegetable broth
    • 1 teaspoon Kosher Salt
    • 1/2 teaspoon Black Pepper

    Stir carefully to avoid splashing hot tomato sauce.

  5. Cook the pasta in the sauce. Add the spaghetti, pressing it down with tongs as it softens, and stir frequently to keep the pasta from sticking while it cooks for 10 to 12 minutes.
    • 12 ounces spaghetti

    Use oven mitts or dry pot holders if you need to steady or move the hot pot.

  6. Remove from heat. When the spaghetti is al dente and the sauce is thickened and glossy, remove the pot from the heat.

    Use oven mitts when handling the hot pot.

  7. Finish and serve. Stir in the fresh basil, then taste and adjust seasoning as needed before serving warm.
    • 1/2 cup basil — chopped

Notes

Stir the pasta frequently while it cooks so the spaghetti does not stick together in the one-pot sauce.

Let leftovers cool slightly before refrigerating in a covered container.

Serving suggestions

Top with extra chopped fresh basil if desired.

Cooking safety

Use oven mitts when handling the hot pot.
