In this recipe I use a super simple and delicious sauce made popular by Marcella Hazan, which is just canned tomatoes, butter, and onion. It's buttery, slightly sweet, packed with flavor and perfect for picky eaters.

Ingredients

Ingredient Notes
Canned San Marzano Tomatoes - San Marzano tomatoes are a specific variety grown in volcanic soil near Naples, Italy. They are a sweeter variety of tomato that is less acidic and milder with fewer seeds. For the best flavor and texture, use whole San Marzano tomatoes. Diced San Marzano tomatoes or other high-quality canned whole tomatoes will also work.
Butter - Butter adds richness and a silky texture to the sauce. You can substitute olive oil if you prefer a lighter flavor, but butter gives it a slightly sweet and creamy taste.
Parmigiano-Reggiano - This cheese brings a nutty and salty depth that that i love with this pasta sauce. You can substitute Parmesan if needed.
