A good marinara is one of those foundational recipes that quietly makes everything else in your kitchen better, and this one is genuinely hard to beat. San Marzano tomatoes, fragrant garlic, a pinch of red pepper flakes, and a generous pour of extra-virgin olive oil come together into something that tastes like it simmered all day — even when it didn't. For anyone managing PCOS, this sauce is a smart staple because it's built entirely from whole, minimally processed ingredients with no hidden sugars, refined starches, or inflammatory seed oils lurking in the background. The optional half-teaspoon of granulated sugar is just there to balance acidity if your tomatoes need it, keeping the overall glycemic load low and the ingredient list clean. Crushing the tomatoes by hand keeps the texture rustic and alive, and that final drizzle of olive oil stirred in off the heat adds a richness that makes the whole thing feel indulgent without working against your goals. Toss it over zucchini noodles, spoon it onto roasted vegetables, or use it as a base for a protein-packed baked egg dish — this sauce earns its place in your weekly rotation fast.

Pour the tomatoes and their juices into a large bowl and crush them by hand until broken into rough, uneven pieces — some chunks are fine.
Heat 3 tbsp olive oil in a large saucepan over medium-low heat. Add the sliced garlic and red pepper flakes and cook, stirring occasionally, until the garlic is pale golden and fragrant, about 3–4 minutes. Watch closely, as the garlic can brown quickly.
