This buttery tomato sauce, inspired by Marcella Hazan, couldn’t be easier to make, and you most likely have the ingredients in your pantry. You will need a Vitamix or other high-powered blender, so if you don’t already own one, this recipe may be the reason to add one to your cart the next time you’re at Costco.
And, oh my … this is soooooo much better than anything you’d find on the shelf at the market.
Make a batch or two this weekend to stash away in the freezer. You’ll never look at jarred tomato sauce again!

This buttery tomato sauce freezes well and is amazing over pasta or pizza.
Ingredients
- 1 28-ounce can San Marzano tomatoes
- 1 medium onion, quartered
- 6 tablespoons butter
- ½ teaspoon sea salt, or to taste
Instructions
- Combine the tomatoes and their juices along with the onion and butter in a medium saucepan.
- Bring to a boil over medium-high heat, then reduce to low.
- Cover and simmer for 40-45 minutes, stirring occasionally.
- Once the sauce has thickened, carefully transfer it to a high-powered blender and pulse until smooth.
- Add salt to taste.
- Serve immediately, or freeze.

This is really foolproof and does freeze beautifully. I have served it over braised meat as well as pasta.
