This is the best tomato sauce, in my opinion. Inspired by Marcella Hazan’s iconic three-ingredient method, this lighter version combines high-quality canned tomatoes, a halved onion, and a touch of butter to deliver a silky, flavorful sauce that clings beautifully to pasta. No garlic, no oil, no sugar—just three primary ingredients plus salt. I prefer to trim the butter slightly for an everyday, weeknight-friendly version that still has that rich, buttery depth.

Tomato Sauce with Onion and Butter
Marcella Hazan’s simple tomato sauce has been celebrated for decades because it transforms a handful of pantry staples into an elegant, velvety sauce. This lighter adaptation keeps the same spirit—tomatoes, onion, and butter—while using canned tomatoes for consistency year-round and reducing the butter to keep the sauce lighter. The result is a clear, concentrated tomato flavor with a smooth mouthfeel and comforting richness.
Why This Recipe Works

Marcella Hazan introduced this minimalist tomato sauce in her first cookbook in 1973. The original called for fresh tomatoes and a generous amount of butter. Over the years, testing with less butter led me to a lighter version that retains the sauce’s luxurious texture and sweet, rounded finish. Two tablespoons of butter still create that silky feel without weighing it down.
- Minimal ingredients, maximum flavor: Three main ingredients plus salt keep the sauce pure and balanced.
- Less butter, same texture: Reducing the butter keeps it lighter while maintaining a velvety finish.
- Canned tomatoes for convenience: High-quality canned tomatoes provide reliable flavor year-round.
- Dietary flexibility: Vegetarian and can be adapted to be vegan with dairy-free butter; naturally gluten-free.

Ingredients You’ll Need
Gather simple, high-quality ingredients for the best result. Exact measurements are listed in the recipe card below.

- Butter: Two tablespoons provide richness. Using salted butter is fine; if you use unsalted, adjust salt to taste.
- Crushed tomatoes: Choose a high-quality canned product (crushed tomatoes or whole peeled tomatoes that you crush by hand).
- Onion: Peel and cut a medium onion in half—no dicing required.
- Salt: A little kosher salt brightens the tomatoes and balances the flavors.
How to Make Tomato Sauce
This sauce is mostly hands-off and forgiving. You only need one pot and about 40 minutes from start to finish.


- Combine and simmer: Place the crushed tomatoes, butter, halved onion, and salt in a medium pot. Bring to a gentle boil, then reduce heat to medium-low and simmer, covered, until the onion is very soft—about 30 to 40 minutes.
- Finish and serve: Remove and discard the onion (or puree it into the sauce for extra body). Taste and adjust salt, then toss the sauce with your favorite pasta.
