Heirloom Tomato Confit Ingredients
A simple method to preserve the best of summer.

- 3 basil sprigs
- 4 cloves garlic, thinly sliced lengthwise
- Kosher salt
- ½ cup extra-virgin olive oil
How To Make Heirloom Tomato Confit
A step-by-step guide to this elegant preserve.
- Prep the Oven and Tomatoes: Preheat your oven to 350°F. Bring a large pot of water to a boil and prepare a separate large bowl of ice water. Using a paring knife, score a shallow “X” in the bottom of each tomato.
- Blanch and Peel: Place the tomatoes in the boiling water for about 10 seconds. Using a slotted spoon, immediately transfer them to the ice bath to stop the cooking. Once they are cool enough to handle, the skins should peel away easily, starting from the scored X.
- Arrange and Roast: In a shallow baking dish, arrange the peeled tomatoes with their cored sides down. Tuck the basil sprigs and sliced garlic in and around the tomatoes. Sprinkle generously with kosher salt and drizzle evenly with the olive oil.
- Cool and Store: Bake for about 50 minutes, until the tomatoes are very tender but still holding their shape. Let the confit cool completely in the baking dish. Once cooled, you can transfer the tomatoes and all their flavorful juices and oil to quart-size glass jars for storage.

Recipe Tips
For perfect, tender, flavor-packed tomato confit.
- What is tomato confit? “Confit” is a classic French preservation technique that involves slow-cooking an ingredient in fat—in this case, olive oil. This process gently cooks the tomatoes, making them incredibly tender and concentrating their natural sweetness and flavor.
- What are the best tomatoes to use for confit? Use the most flavorful, ripe, in-season tomatoes you can find. Heirlooms are wonderful for their variety and taste, but good-quality Roma or vine-ripened tomatoes also work beautifully. The key is flavor, not a specific type.
- Do I have to peel the tomatoes? While you can make this with the skins on, peeling them is highly recommended for the best texture. The skins can become a bit tough and chewy during the roasting process. The quick blanching step makes peeling them incredibly easy.
- How can I use tomato confit? It’s incredibly versatile! Spoon it over toasted crusty bread, toss it with pasta, serve it alongside grilled chicken or fish, chop it up to make a luxurious bruschetta topping, or serve it as part of an antipasto platter with cheese and cured meats.
What To Serve With Heirloom Tomato Confit
Simple pairings that let this delicious condiment shine.
Tomato confit is a fantastic gourmet ingredient to have on hand. Use it to elevate simple dishes:

How To Store Heirloom Tomato Confit
Properly preserving your summer harvest.
- Refrigerate: The confit can be stored in an airtight jar in the refrigerator for up to 2 weeks. Make sure the tomatoes are completely submerged in the olive oil, as the oil acts as a preservative.
- Freeze: For long-term storage, this confit freezes exceptionally well. Transfer the cooled tomatoes and their juices to freezer-safe jars, leaving about 1/2 inch of headspace. It can be frozen for up to 1 year. Thaw in the refrigerator overnight before using.

FAQs
Absolutely. While basil is classic, you could also use sprigs of fresh thyme or rosemary. A few dried oregano leaves would also be a delicious addition.
Bitterness can sometimes come from the garlic if it’s overcooked or from a lower-quality olive oil. Ensure you are using a good quality extra-virgin olive oil and that the garlic is just gently cooked and infused in the oil, not browned or burned.
Yes, you can make a stovetop version. Place all the ingredients in a saucepan and cook over very low heat, maintaining a gentle simmer, for about 45-60 minutes, until the tomatoes are very tender. The oven method provides a more even, gentle heat.
