Here are 5 best tomatoes for red pesto. If you’re making red pesto from scratch, the tomatoes you choose can change the sauce’s sweetness, intensity, color, and texture. Because tomatoes are one of the main ingredients in red pesto, varieties with concentrated flavor and relatively low moisture tend to work especially well.
1. Sun Dried Tomatoes
Sun-dried tomatoes are the classic option when you want a bold, concentrated tomato flavor. Removing much of the tomato’s water intensifies its sweetness and savory character, making the finished pesto rich without requiring a large quantity.
Choose:
- Oil-packed sun-dried tomatoes for a softer texture
- Dry-packed tomatoes when you want more control over the amount of oil
- Tomatoes without excessive seasoning if you’re making your own pesto
Best for: Pasta, pizza, sandwiches, chicken, and bruschetta.
2. Roma Tomatoes
Roma tomatoes are a good fresh option because they have relatively firm flesh and fewer seeds than many larger slicing tomatoes.
For red pesto, roast them first to remove excess moisture and concentrate their flavor. Roasting also brings out their natural sweetness.
Best for: Fresh tomato pesto, roasted red pesto, and recipes where you want a lighter tomato flavor.
3. San Marzano Tomatoes
San Marzano tomatoes are prized for their balanced flavor and meaty texture. When using them for red pesto, drain them thoroughly before blending.
They’re particularly useful when you want a smoother, more sauce-like pesto rather than the intensely concentrated flavor of sun-dried tomatoes.
Best for: Pasta sauces, pizza, and a softer red pesto.
4. Cherry Tomatoes
Cherry tomatoes bring natural sweetness and a fresh flavor to homemade red pesto. Roasting them before blending concentrates their flavor and gives the pesto a deeper character.
Because cherry tomatoes contain more moisture than sun-dried tomatoes, roast them until some of their liquid has evaporated.
Best for: Fresh-tasting pesto, pasta, crostini, and summer dishes.
5. Grape Tomatoes
Grape tomatoes are similar to cherry tomatoes but tend to be slightly firmer and less watery. Roasting them can produce a flavorful base for a fresh tomato pesto.
They’re a practical choice when you want to use readily available fresh tomatoes rather than preserved ones.
Best for: Roasted red pesto forward recipes.
Tomato Comparison
| Tomato | Flavor | Moisture | Best Use |
| Sun-dried | Intense, sweet, savory | Low | Classic red pesto |
| Roma | Mild, concentrated | Moderate | Fresh tomato pesto |
| San Marzano | Balanced, rich | Moderate | Smooth red pesto |
| Cherry | Sweet, bright | Higher | Roasted fresh pesto |
| Grape | Sweet, slightly firm | Moderate | Roasted pesto |
Which Tomato Should You Choose?
For the most intense and traditional-style red pesto, use sun-dried tomatoes. If you are making it specifically for classic red pesto sauce for pasta, sun dried tomatoes are a great choice because their concentrated flavor holds up well with pasta.
For a sweeter, fresher variation, try cherry or grape tomatoes and roast them first. If you want a smoother sauce with a more tomato-sauce-like character, drained San Marzano tomatoes can work well.
The most important consideration isn’t just the variety—it’s the amount of moisture. Excess water can make pesto thin and dilute its concentrated flavor. Roasting or draining fresh tomatoes before blending can make a noticeable difference.
Tips for Preparing Tomatoes for Red Pesto
- Drain oil-packed tomatoes if the recipe calls for separate olive oil.
- Pat dry dry-packed sun-dried tomatoes before using them.
- Roast fresh tomatoes to concentrate their flavor.
- Remove excess seeds and liquid when working with particularly juicy tomatoes.
- Taste before adding extra salt, especially when using preserved tomatoes.
- Blend gradually so you can control the final consistency.
Final Thoughts
The best tomatoes for red pesto depend on the style you’re after. Sun-dried tomatoes give you the deepest and most concentrated flavor, while roasted Roma, cherry, or grape tomatoes create a fresher homemade version. San Marzano tomatoes offer another option when you want a smoother, softer tomato character.
If you’re making red pesto specifically for pasta or pizza, start with sun-dried tomatoes for a bold flavor. For a lighter fresh-tomato version, roasting your tomatoes first is a simple way to concentrate their flavor without making the pesto watery.
