Tomato Concassé: The Essential Technique for Perfect Tomatoes
Tomato concassé is a classic culinary technique revered in refined cooking—whether French, Italian, or global cuisines—for transforming fresh tomatoes into chopped, skinless, seedless flesh. This versatile base elevates sauces, salads, and composed dishes by delivering pure tomato flavor without the distraction of skins or seeds. This comprehensive guide details every step, ingredient, and creative use of concassé, empowering home cooks to master an essential kitchen skill.
What is Tomato Concassé?
Tomato concassé refers to tomatoes that have been peeled, seeded, and chopped. While the term is French, this technique transcends borders, appearing in Italian sauces, Mediterranean salads, and contemporary culinary presentations. The goal is a refined tomato preparation, maximizing flavor and texture for applications where purity matters—from pasta sauces to elegant garnishes.
- Peeling: Removes the tough skin for a tender, uniform texture.
- Seeding: Eliminates bitterness and excess moisture.
- Chopping: Produces even, bite-sized pieces for consistent cooking and presentation.
Why Use Tomato Concassé?
This preparation is favored when recipes demand the clean flavor of fresh tomato, a smooth mouthfeel, or a polished visual result. Tomato skins can disrupt texture, while seeds add unwanted liquid or bitterness. Concassé ensures only the pure, fruity essence of tomato shines through.
- Refined sauces: Create light, vibrant tomato sauces without skins or seeds.
- Garnishes: Decorate plates with jewel-like tomato cubes.
- Stuffings: Fill vegetables or artichoke bottoms with seasoned concassé.
- Salads: Enhance with clean, uniform tomato pieces.

This method yields perfectly peeled, seeded, and diced tomatoes ready for countless culinary uses. Follow these precise steps for foolproof results.
Ingredients & Equipment
- Fresh, ripe tomatoes (Roma or vine tomatoes preferred)
- Large saucepan or pot
- Paring knife
- Slotted spoon
- Bowl of ice water
- Cutting board
- Chef’s knife
Preparation Steps
- Core and Score the Tomatoes
- Use a paring knife to cut out the core (stem end), making a small, inverted pyramid shape.
- Score a shallow “X” on the bottom of each tomato. This helps the skin release during boiling.
- Blanch the Tomatoes
- Bring a large pot of water to a full rolling boil.
- Drop in the scored tomatoes for 30 seconds to 1 minute—just until the skin starts to blister and curl at the scored X.
- Shock in Ice Water
- Quickly transfer blanched tomatoes to a bowl of ice water.
- This halts cooking, preserving texture and color.
- Peel the Skins
- Once cooled, gently slip off the loosened skins using your fingers or a knife.
- Quarter and Seed the Tomatoes
- Slice peeled tomatoes into quarters.
- Using your fingers or a small spoon, remove the seeds and watery pulp, leaving only the firm flesh.
- Dice the Tomato Flesh
- Chop tomato flesh into desired size—usually small, uniform cubes for sauce or larger dice for salads.
Chef’s Tips for Success
- Select ripe but firm tomatoes for best flavor and easy handling.
- Don’t overcook during blanching—skins should loosen, but flesh must remain firm.
- Ice bath is critical to avoid mushiness.
- Discard skins and seeds to achieve the desired purity.

Frequently Asked Questions (FAQs)
What does ‘concassé’ mean?
The French term ‘concassé’ means ‘to crush or chop.’ In culinary contexts, tomato concassé refers specifically to tomatoes that are peeled, seeded, and chopped.
Do I need to use Roma tomatoes?
Roma (plum) tomatoes are ideal for concassé due to their dense flesh and low moisture, but any ripe, firm variety works.
Can tomato concassé be made in advance?
Yes, finished concassé can be stored in the refrigerator in an airtight container for up to 2 days. Season and use as needed.
What recipes use tomato concassé?
Concassé is a base for fresh tomato sauces, bruschetta toppings, salads, stuffings (like artichoke bottoms), and as a refined garnish for meats or fish.
Does tomato concassé require cooking?
Blanching is used to remove skins, but tomato concassé itself may be served raw (in salads or garnishes) or cooked into sauces and fillings.

Comparison Table: Raw vs. Concassé vs. Puree
| Form | Preparation | Texture | Uses |
|---|---|---|---|
| Raw Tomato | Whole or sliced, unpeeled, seeded | Firm, often uneven | Salads, snacking, roasting |
| Tomato Concassé | Peeled, seeded, diced | Tender, uniform cubes | Refined sauces, garnishes, stuffings |
| Tomato Puree | Blended, often unpeeled | Smooth, liquid | Soups, liquid sauces |
Expert Insights: Secrets for Best Concassé
- Never skip the ice bath. Rapid cooling ensures tomatoes maintain their texture.
- Score only shallowly—deep cuts allow water to penetrate and soften the flesh, making dicing messy.
- Season immediately after chopping to bring out full tomato flavor.
- Use concassé quickly for freshest taste; prolonged storage can lead to watery separation.
- Pair with flavors that complement tomato’s acidity: olive oil, fresh basil, mild cheese, artichokes, or grilled poultry.
