Slow-roasting tomatoes is a simple yet transformative technique that involves cooking the tomatoes at a low temperature for an extended period. This slow and gentle cooking process allows the tomatoes to slowly release their moisture, intensifying their taste and creating a caramelized exterior. As the tomatoes slowly roast, their natural sugars concentrate, resulting in a deep and complex flavor profile that is tangy and sweet. The result is a burst of incredible flavor that can elevate any dish. Slow-roasted tomatoes can add depth and complexity to pasta sauces, soups, sandwiches, and salads.


Tomatoes- cherry, grape, Roma, or on the vine. Any kind will do.

Olive oil

Sea salt

Organic raw sugar


If using cherry or grape tomatoes, leave them whole. If using a larger variety of tomatoes, cut them in half or quarters, depending on the size and your preference.

Place the tomatoes on a cookie sheet and drizzle them with olive oil- just enough to give them a thin coating.

Sprinkle with sea salt and a tiny bit of sugar. I estimate I use about a 1/2 teaspoon of sugar for one pound or so of tomatoes. You can skip the sugar, but depending on the type and flavor of the tomatoes, they can turn out to be a bit too tart after being cooked, so adding a small pinch of sugar cuts the acidity of the tomato and creates a rich caramelized flavor.

Toss the tomatoes to coat them with olive oil, salt, and sugar. I use my hands to toss them while they are on the cookie sheet.

Roast the tomatoes at 250 degrees Fahrenheit for about two to two and a half hours. Check on them after two hours to determine if they are done. The result should be caramelized and roasted but not browned.

Store them in an air-tight container for up to two weeks.

This is a fabulous ingredient to cook while you are at home on the weekend. The tomatoes take less than 10 minutes to prepare, and the oven does all the work while you do something else.

You can experiment with adding additional ingredients to the tomatoes while roasting, such as fresh minced garlic or fresh thyme.

I often cook "au pif," as we say in France, which means cooking without an exact recipe and by "feel" using your intuition.  You’ll often find guidelines in many recipes versus exact quantities.  Write to me here if you have any questions about the recipes.
