- Salt (optional, to taste)

Magic 3-Ingredient Pasta Sauce (Marcella Hazan Recipe): From Prep to Plate

Step 1: Prepare the Ingredients
Begin by gathering all your ingredients. Open the can of whole tomatoes and set aside. You might want to crush them slightly with your hands or a fork to break them up, but this is optional.
Step 2: Combine in Pot
In a large pot or Dutch oven, add the entire can of tomatoes along with the juice, the butter, and the halved onion.
Step 3: Simmer
Place the pot over medium heat. As it heats up, bring the mixture to a gentle simmer, stirring occasionally. Allow it to simmer uncovered for about 45 minutes. This step is crucial as it allows the flavors to meld beautifully.
Step 4: Remove the Onion
Once the sauce has thickened and the flavors have developed, remove the onion halves from the sauce. You can either discard them or chop them finely and return them to the sauce for added texture.
Step 5: Season to Taste
Taste the sauce and season with salt if desired. Remember, the butter adds a rich flavor, so be mindful of how much salt you add.
Step 6: Serve
Toss your cooked pasta of choice with the sauce, ensuring every strand is coated with the luscious tomato and butter mixture. Serve with grated Parmesan cheese if you like, and enjoy the magic of this simple yet spectacular sauce.
Adaptations for Special Diets

- Vegan: Substitute the butter with a plant-based alternative like vegan butter or olive oil.
- Gluten-Free: Use gluten-free pasta varieties when serving.
- Low-Carb: Serve with zucchini noodles or spaghetti squash instead of traditional pasta.
Problems & Prevention
- Too Acidic: If the sauce tastes too acidic, add a pinch of sugar to balance the flavors.
- Too Thick: If your sauce thickens too much, add a splash of water or vegetable broth to achieve your desired consistency.
- Too Watery: If the sauce is too thin after simmering, continue to simmer it uncovered for a longer period to reduce the liquid.
How to Store & Reheat
Store any leftovers in an airtight container in the refrigerator for up to 5 days. For longer storage, you can freeze the sauce in freezer-safe containers for up to 3 months. To reheat, simply thaw overnight in the refrigerator and warm gently on the stove over low heat. Add a splash of water or broth if the sauce has thickened too much during storage.
