If you have an abundance of fresh tomatoes, oven-dried tomatoes are a delicious and long-lasting way to preserve them. They are perfect for adding to salads, pasta dishes, sandwiches, or as a snack. This guide will show you how to dry tomatoes in the oven while maintaining rich flavor and texture.
Ingredients and Tools
- Fresh ripe tomatoes
- Everything Bagel seasoning (or your preferred seasoning)
- Parchment paper or silicone baking mat
- Baking sheet
- Oven or convection oven
Optional: Olive oil for drizzling before baking.

Step-by-Step Instructions
Step 1: Prepare the Tomatoes
- Wash and slice the tomatoes into even, thin rounds.
- Remove seeds if desired, though leaving them can add texture.
- Sprinkle each slice with your choice of seasoning, such as Everything Bagel seasoning, salt, or herbs.
Step 2: Arrange on a Baking Sheet
- Line a baking sheet with parchment paper or a silicone mat.
- Place tomato slices in a single layer, ensuring they do not overlap to allow even drying.
Step 3: Bake Slowly
- Preheat your oven to 170°F (77°C).
- Bake the tomatoes for approximately 12 hours. Using a convection oven can speed up the process slightly.
- Halfway through, check for moisture levels and adjust slices if necessary.
Step 4: Store for Later Use
- Once fully dried, allow tomatoes to cool completely.
- Store them in a clean jar or airtight container.
- Properly dried and stored, they can last all winter or until fully consumed.
Tips for Perfect Oven-Dried Tomatoes
- Use Ripe Tomatoes: Fully ripe tomatoes provide the best flavor and natural sweetness.
- Uniform Slices: Slice tomatoes evenly to ensure consistent drying.
- Low and Slow: Baking at a low temperature preserves flavor and prevents burning.
- Season to Taste: Experiment with herbs, garlic, or spices for custom flavor profiles.
- Storage: Keep dried tomatoes in a cool, dry place or refrigerate to extend shelf life.
Uses for Oven-Dried Tomatoes
- Add to pasta, risotto, or grain bowls for concentrated tomato flavor.
- Include in salads or sandwiches for added texture and sweetness.
- Blend into spreads, dips, or sauces for intense tomato notes.
- Enjoy as a healthy snack, straight from the jar.
