There is something almost magical about what a hot oven does to a pile of tomatoes — the edges caramelize, the juices concentrate, and the whole thing collapses into something far more complex than any sauce you could pull from a jar. Plum tomatoes roast alongside onion wedges and whole unpeeled garlic cloves until they're deeply golden and just beginning to char, building a smoky, sweet foundation that no amount of stovetop simmering can replicate. Fresh basil, dried oregano, a pinch of red pepper flakes, and a subtle warmth from turmeric round out the flavor in a way that feels both rustic and a little unexpected. Everything gets blended with the pan juices and a final drizzle of good olive oil until silky smooth, then brought to a gentle simmer to pull it all together. This is a completely plant-based sauce built entirely from vegetables, herbs, and olive oil — no meat, no broth, no hidden animal proteins to track down on a label. It works beautifully over pasta, spooned onto pizza dough, or stirred into a grain bowl, and it freezes like a dream so you can make a big batch and thank yourself later.

Preheat the oven to 425°F (220°C). Arrange the tomato halves cut-side up on a large rimmed baking sheet. Scatter the onion wedges and unpeeled garlic cloves around the tomatoes. Drizzle with 3 tbsp of the olive oil and sprinkle with the salt, black pepper, and red pepper flakes.
Roast on the center rack for 40–45 minutes, until the tomatoes are deeply caramelized at the edges, collapsed, and beginning to char in spots, and the onion wedges are softened and golden at the tips.
