Few sauces are as deeply satisfying as a slow-simmered tomato sugo, and this one earns every minute it spends on the stove. Crushed San Marzano tomatoes, golden garlic, a whisper of red pepper flakes, and fresh basil come together into something that tastes like it took all day — even though it's mostly hands-off simmering. For anyone navigating alpha-gal syndrome, this kind of recipe is a genuine relief: it's built entirely on plant-based pantry staples and olive oil, with no hidden meat products, mammalian-derived broths, or mystery additives to second-guess. The optional tablespoon of butter at the finish adds a silky richness, and since it comes from dairy rather than red meat, it remains a safe choice within alpha-gal guidelines — though the sauce is absolutely beautiful without it too. Tearing in the basil off the heat keeps the flavor bright and floral rather than cooked-down and flat. Spoon it over pasta, use it as a pizza base, or ladle it onto polenta — this is the kind of versatile, crowd-pleasing sauce worth keeping in your regular rotation.

Pour the tomatoes and their juices into a large bowl and crush them by hand, squeezing each tomato until broken into rough, uneven pieces. Set aside.
Warm the olive oil in a large saucepan over medium-low heat until it shimmers. Add the garlic and red pepper flakes and cook, stirring occasionally, until the garlic is pale golden and fragrant, about 3–4 minutes. Watch closely — the garlic can color quickly.
