Most tomato sauces rely on store-bought canned tomatoes, but I love turning to fresh, in-season heirlooms. Their natural sweetness and vibrant flavor create a sauce that’s rich and complex without a single added sugar. Plus, the aroma of simmering tomatoes, garlic, and basil is a scent that instantly transports me to a summer garden.
In this recipe, I focus on slow, gentle simmering to coax out every ounce of flavor. It’s a simple process but one that makes a big difference in the finished dish. Cooking this sauce makes me feel connected to the seasons and reminds me of childhood weekends spent prepping garlic and chopping herbs.

Heirloom Tomato Sauce
Ingredients
Equipment
Method
- Wash and halve the heirloom tomatoes, then remove the core if desired.
- Heat olive oil in a large skillet over medium heat until shimmering and fragrant.
- Add the minced garlic to the hot oil and sauté for about 30 seconds, until it becomes fragrant and slightly golden.
- Stir in the prepared tomatoes and cook at a gentle simmer, stirring occasionally, until the tomatoes start breaking down and release their juices, about 15 minutes.
- Reduce the heat to low, add torn basil leaves, and continue simmering gently for another 20-25 minutes, stirring every now and then, until the sauce thickens slightly and the flavors meld.
- Season the sauce with salt and freshly ground black pepper to taste, then remove from heat.
- Serve the sauce hot over pasta or alongside your favorite dishes, garnished with additional basil if desired.
