This roasted tomato sauce is simple, fresh, and full of bright, layered flavor. By roasting the tomatoes and garlic you concentrate their sweetness and add a subtle caramelized note. The final puree, finished with fresh basil and a splash of apple cider vinegar, is versatile enough to use on pasta, baked dishes, pizzas, or as a dipping sauce.

This recipe uses fresh tomatoes rather than canned, giving you a cleaner, more vibrant tomato flavor. It’s an easy method that yields about 3 cups of sauce — enough for a family meal or for preserving in the fridge or freezer for later.

What is tomato sauce?

Tomato sauce is a cooked tomato preparation made by reducing tomatoes with salt and other aromatics until a flavorful, cohesive sauce forms. It’s a foundation for many Italian and global dishes and can be adapted to be chunky or smooth, simple or complex.

What You Need for Oven Roasted Tomato Sauce

Seven simple ingredients give this sauce its depth and balance. All are easy to find and work together to highlight the natural flavor of the tomatoes.

• Tomatoes: 8 medium to large tomatoes are ideal; they’re easiest to peel after roasting.
• Olive oil: A couple of tablespoons help roast and tenderize the tomatoes while adding richness.
• Garlic cloves: Roasted garlic becomes sweet and mellow—don’t skip it.
• Salt and pepper: Season to taste. Add gradually and taste as you blend.
• Fresh basil: Adds brightness and herbal aroma; leave in larger leaves for texture or blend finer if preferred.
• Apple cider vinegar: A teaspoon balances and brightens the sauce, helping flavors pop.

Roasting Tomatoes for Sauce

Step 1: Oil & Roast Tomatoes

Preheat the oven to 400ºF (200ºC). Wash and halve the tomatoes, then place them cut-side up on a baking sheet. Drizzle generously with olive oil and season with salt and a little pepper. Roast for about 30 minutes, then add the garlic cloves to the pan and roast an additional 20–30 minutes until the tomatoes begin to collapse and brown at the edges. Keep an eye on the garlic to prevent burning.

Step 2: Peel Tomatoes

Allow the roasted tomatoes to cool for a few minutes so they are safe to handle. The skins should slip off easily—discard the skins. Peeling ensures a smooth, silky texture; roasted skins can become tough if left in.

Step 3: Blend

Transfer the roasted tomatoes, roasted garlic, basil, and apple cider vinegar to a high-speed blender or food processor. Blend until smooth or to your desired texture. Taste and adjust salt and pepper. For a touch of sweetness, optionally add a teaspoon or two of maple syrup, but this recipe is designed to avoid added sugar.

Step 4: Serve or Store

Serve the sauce immediately over pasta, chicken, or vegetables. Alternatively, let it cool and store in a mason jar or airtight container in the refrigerator. This recipe yields approximately 3 cups of sauce.
