Pasta with Oil-Free Marinara

Other Fast Without Oil Published March 08, 2026

Marinara sauce does not need oil. Tomatoes contain enough natural sugars and acids to build a sauce entirely on their own — you just need to water-sauté the garlic, add the tomatoes, and let time do the work. A long, slow simmer concentrates the flavors and thickens the sauce to the point where you genuinely will not miss the olive oil. Pasta and marinara is the simplest weeknight no-oil meal there is.

Use the best canned tomatoes you can find. San Marzano or similar fire-roasted varieties make this sauce taste like far more work than it actually is.

FASTING LEVEL: Fast Without Oil (cooked food permitted, no oil, no wine)
SERVINGS: 4
TIME: 35 minutes

INGREDIENTS

- 500g dried pasta (spaghetti, penne, or rigatoni — any shape works)
- 2 cans (800g) whole peeled tomatoes (San Marzano preferred)
- 6 cloves garlic, thinly sliced
- 1/2 teaspoon red pepper flakes
- 1 teaspoon dried oregano
- Large handful of fresh basil leaves
- 1 teaspoon sugar (optional, if tomatoes are very acidic)
- Salt and black pepper to taste
- Pasta cooking water, reserved

METHOD

1. Heat a large saucepan over medium heat. Add the garlic with 3 tablespoons of water. Cook, stirring, for 1-2 minutes until the garlic is softened and fragrant but not browned.

2. Add the red pepper flakes and oregano. Stir for 15 seconds.

3. Pour in the canned tomatoes. Crush them with a wooden spoon or your hands as they go in. Add the sugar if using. Season with salt.

4. Bring to a simmer and cook for 25-30 minutes, stirring occasionally. The sauce should reduce and thicken noticeably. Taste and adjust seasoning.

5. Meanwhile, cook the pasta in heavily salted boiling water until 1 minute short of al dente. Reserve 1 cup of pasta water, then drain.

6. Add the drained pasta to the sauce. Toss over medium heat for 1-2 minutes, adding splashes of pasta water to create a silky, clinging sauce. The starchy water replaces the emulsifying role that oil usually plays.

7. Tear the fresh basil over the top. Serve immediately.

NOTES

- The pasta water is critical. The starch in the water binds the sauce to the pasta in a way that mimics the effect of oil. Do not skip this step.
- Whole canned tomatoes are always better than pre-crushed. They are packed at peak ripeness and have more flavor and less processed taste.
- A few tablespoons of capers or chopped olives added in step 4 bring brine and salt that compensate for the missing oil.
- Dried pasta is vegan and fasting-compliant. Check fresh pasta labels — many contain eggs.
