Sun-Dried Tomatoes with Garlic
- Time: 15 min active + 270 min roasting
- Flavor/Texture Hook: Tangy, chewy, and mahogany colored
- Perfect for: Meal prep, antipasti, and nutrient dense snacks
The smell of warm garlic and concentrated tomato always reminds me of a slow Sunday afternoon. There is something about the way the house smells when you have a tray of tomatoes roasting for hours. It is earthy and salty, like a Mediterranean coast in August.
You don't need a fancy dehydrator to get this result. I used to think I needed professional gear, but a low oven does the job just as well. These homemade sun dried tomatoes are a quick win for anyone who wants a high impact ingredient ready in the pantry.
Once you have a jar of these Sun Dried Tomatoes, your weeknight meals get a huge boost. You just pluck a few slices out of the oil and toss them into a pasta or onto a salad. It is the easiest way to add deep, complex flavor without spending an hour at the stove.
Easy Homemade Sun Dried Tomatoes
The goal here is dehydration. We are removing the water to concentrate the natural sugars and acids. By doing this, the flavor becomes intense and the texture changes from juicy to leathery.
Since we are using a very low temperature, the risk of burning is low, but the patience requirement is high. You cannot rush this process. If you crank up the heat, you'll just bake the tomatoes instead of drying them, which ruins that chewy consistency.
The Trick Behind the Texture
Water Removal: Slow evaporation concentrates the natural acids and sugars. This turns a mild tomato into an umami heavy ingredient.
Low Temperature: Keeping the oven at 105°C prevents the sugars from scorching. It mimics the gentle heat of the sun.
Gathering Your Essentials
Roma tomatoes are the best choice because they have thicker walls and less water than cherry or beefsteak varieties. This means they dry faster and hold their shape. I prefer organic Romas for a cleaner, more nutritious result.
The salt does a lot of the heavy lifting here. It doesn't just season the fruit, it actually pulls the moisture to the surface so it can evaporate more quickly. Using a high-quality sea salt adds a nice mineral depth.
For the infusion, extra virgin olive oil acts as both a flavor carrier and a preservative. The garlic and dried herbs infuse into the fat, which then coats the tomatoes and keeps them from oxidizing. It's a simple way to protect the nutrients while adding aromatics.
Equipment You Will Need
You will need two large rimmed baking sheets. Using two instead of one prevents overcrowding, which is the main reason batches fail to dry.
Parchment paper is a must. Without it, the sugars in the tomatoes can stick to the metal, and you'll end up peeling the skins off during the flip.
A sterilized glass canning jar is the final piece. Since the tomatoes are stored in oil, you need a non reactive container that seals tightly to keep air out.
The Full Cooking Process
Preparing the Tomatoes
Preheat your oven to 225°F (105°C). Line two large rimmed baking sheets with parchment paper. Slice 900g of Roma tomatoes into 1/4 inch rounds. Arrange the slices in a single layer on the sheets without overlapping. Sprinkle 5g of sea salt evenly across the slices.
Note: Salt draws out moisture faster.
Slow Roasting for Depth
Roast for 270 minutes. Rotate the pans and flip the tomatoes every 90 minutes. Continue until they are shriveled, mahogany colored, and leathery but flexible. If they feel brittle, take them out immediately.
This is the most important part to make Sun Dried Tomatoes that aren't tough.
Infusing the Garlic Oil
Gently warm 120ml of extra virgin olive oil in a small pan over low heat. Add 3 thinly sliced garlic cloves and 5g of dried oregano plus 2.5g of dried thyme. Heat only until the garlic is translucent and fragrant. Do not let the garlic brown, or it will taste bitter.
Finishing the Preserve
Place the dried tomatoes in a bowl. Toss with the warm garlic oil to coat. Pack them tightly into sterilized glass canning jars. Pour the remaining garlic oil over the Sun Dried Tomatoes until they are completely submerged. Seal with lids. This is how you make Sun Dried Tomatoes that last and stay fresh.
To make SunDried Tomatoes properly, you must ensure the oil covers every piece. Any tomato exposed to air can develop mold. If you aren't sure, just add a bit more oil.
When you decide to make SunDried Tomatoes for the first time, remember that every oven is different. If yours runs hot, you might see the edges curling and darkening at the 3 hour mark. Just keep an eye on them.
Fixing Common Issues
If the edges of your Sun Dried Tomatoes are darkening too fast while the centers stay wet, your oven is likely too hot. This happens often in smaller ovens where the heat is less distributed. I usually lower the temp by 15°C and prop the door open a tiny bit with a wooden spoon to let steam escape.
Another issue is the "soggy middle." This happens if you overlap the slices. Air needs to flow around every single piece to carry the moisture away. If they are touching, they steam instead of dry.
Finally, avoid using tomatoes that are too ripe. If they are mushy, they will collapse and stick to the parchment, making them impossible to flip. Use firm, bright red Romas.
Troubleshooting Guide
| Problem | Fix |
|---|---|
| Burnt edges/wet center | Lower temp by 15°C and prop door open |
| Tomatoes are too soggy | Ensure no overlapping on the tray |
| Garlic oil tastes bitter | Keep heat low; garlic should stay translucent |
| Tomatoes are brittle/hard | Reduce roasting time by 30 minutes |
Simple Flavor Variations
For a bit of heat, stir some red pepper flakes into the oil infusion. This gives the sun-dried tomatoes a spicy edge that complements pasta dishes beautifully. If you prefer an herbal touch, substitute the thyme with finely minced fresh rosemary.
Cherry tomatoes also work well for this process just slice them in half. They tend to dry more quickly due to their size and maintain a sweeter profile. These are a wonderful way to add concentrated flavor to an Italian pasta salad.
This recipe is already vegan friendly. Just make sure you are using unprocessed sea salt. For those who prefer a tangier result, stir a teaspoon of balsamic vinegar into the oil.
Goal Adjustments
| Goal | What to change |
|---|---|
| Spicier flavor | Add 1/2 tsp red pepper flakes to oil |
| Sweeter taste | Use cherry tomatoes instead of Roma |
| Low sodium | Reduce salt to 1/2 tsp or use potassium salt |
Storage and Zero Waste
Store your Sun Dried Tomatoes in the refrigerator. They will stay fresh for about 2 to 3 weeks. Because they are stored in oil, they are well protected, but the fridge keeps the oil from going rancid.
If you have a huge batch, you can freeze them. Put the tomatoes in a freezer safe bag, but leave the oil out. Once frozen, you can thaw them in a bowl of oil for 15 minutes before using.
Don't throw away the tomato stems or the ends you trimmed off. I toss mine into a freezer bag and add them to my vegetable stock. They add a deep, earthy base that you can't get from store-bought bouillon.
When using sun dried tomatoes in oil, always use a clean spoon to scoop them out. Introducing crumbs or food particles into the jar can lead to spoilage. If the oil looks cloudy, it is time to toss the batch.
Serving and Presentation
These are a stellar addition to any charcuterie board. Try pairing them with crusty sourdough, green olives, and sharp provolone; the salt from the cheese provides a great contrast to the concentrated sweetness of the tomatoes.
For a simple meal, use them to enhance a rich marinara sauce. Blending a few oil-packed tomatoes into the sauce adds a depth of flavor that usually requires hours of simmering.
You can also chop them finely and fold them into ricotta cheese. The result is a tangy, creamy spread that is perfect for topping toasted crostini.
If you're adding them to a salad, wait until the very end. This keeps the red color from bleeding into the other vegetables, maintaining a clean look and distinct tastes.
You now have all the information to prepare your own Sun Dried Tomatoes. It requires a few hours in the oven, but you'll be rewarded with a jar of intense flavor that elevates any meal. Once you experience the homemade version, you won't want the store-bought ones.
