Roasting tomatoes low and slow — well, hot and patient — transforms them into something deeply sweet, jammy, and complex in a way that no jarred sauce can replicate. The caramelized edges and collapsed flesh bring out a natural richness that makes this sauce taste like it simmered for hours. What makes this version especially smart is the addition of turmeric, an anti-inflammatory spice that blends seamlessly into the roasted tomato base without changing the flavor profile in any obvious way. Extra virgin olive oil, used generously here, adds healthy fats that support hormone balance — a real priority when managing PCOS. The whole garlic cloves roast in their skins until they're soft and mellow, adding depth without any sharpness, while fresh basil keeps things bright at the finish. Everything gets blended into a silky, vibrant sauce that works over pasta, spooned onto proteins, or stirred into soups. It's the kind of foundational recipe you'll want to keep in your weekly rotation.

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.
