I bought a tiny jar of sun-dried tomatoes at a specialty grocery store last summer. Four ounces. $8.99. I stared at the price tag for a full ten seconds before putting it back and driving home to make my own.
Best decision I made all August.
Here’s the thing most people don’t realize: making homemade sun-dried tomatoes in oil isn’t complicated. It’s just slow. And slow, in cooking, is almost never a bad thing.
What You’ll Actually Need
Start with Roma tomatoes. I’ve tried cherry tomatoes, beefsteak, even some heirloom varieties I picked up at a farmers market, and Romas win every single time. They’re meatier, lower in water content, and they dry more evenly without turning weirdly leathery at the edges. You’ll want about 2 pounds.
For the oil, go with a decent extra-virgin olive oil — nothing outrageously expensive, but not the stuff in the giant plastic jug either. Something in the $10-$14 range works perfectly. You’ll also want garlic (4-5 cloves, thinly sliced), fresh basil, salt, cracked black pepper, and if you’re feeling adventurous, a pinch of chili flakes.
That’s genuinely it. No fancy equipment. No canning experience required.
The Drying Process (This Is Where Patience Pays Off)
Slice your tomatoes in half lengthwise and scoop out the seeds with a spoon. This step matters more than most recipes admit — leaving seeds in makes everything watery, and watery is the enemy of flavor concentration.
Lay them cut-side up on a baking sheet lined with parchment. Drizzle lightly with olive oil, season with salt and pepper, and tuck garlic slices and a few torn basil leaves around them. Now here’s where people get impatient: set your oven to 200°F (about 93°C) and leave them alone for 6 to 8 hours.
So go live your life. Do laundry. Watch something on Netflix. The oven is handling it.
You’re looking for tomatoes that are shrunken, deeply red, and slightly chewy — not brittle, not wet. They should feel like a soft, concentrated version of themselves. Pull them out when they reach that stage, even if the timer hasn’t gone off yet.
Packing Them in Oil the Right Way
This is the part that turns a good ingredient into something genuinely special. Let your dried tomatoes cool completely. rushing this step can create condensation in your jar, which shortens shelf life significantly.
Sterilize a clean glass jar by running it through the dishwasher on a hot cycle, or by pouring boiling water into it and letting it sit for 5 minutes. Pack your tomatoes in snugly, layering with fresh garlic, basil, and a bay leaf if you have one. Then pour olive oil over everything until the tomatoes are fully submerged. Fully. Not mostly. Fully.
Press them down gently to release any air pockets, seal the jar, and refrigerate.
They’ll keep for about 3 weeks in the fridge. And the oil itself? Ridiculously good drizzled over pasta or soaked up with crusty bread.
What Most Guides Get Wrong
Most online recipes skip one honest warning: botulism risk is real when you’re preserving garlic and herbs in oil at room temperature. I’m not trying to scare you, I’m trying to keep you from making a jar that lives on your counter for a month. Keep these refrigerated, use them within 3 weeks, and you’re completely fine.
Also, don’t skip salting before drying. I did that once, thinking I’d season at the end. The tomatoes were flat and a little sad. Salt draws out moisture during drying and concentrates flavor in a way you can’t replicate afterward.
Make a batch this weekend. Use them in pasta, on pizza, in sandwiches, or honestly just straight from the jar with a fork. Once you taste yours against the $8.99 version, you won’t go back.
Promise.
