How to Make Tomato Purée at Home: Step-by-Step Guide
Master the art of homemade tomato purée with expert step-by-step guidance, tips, and troubleshooting for the perfect batch every time.
Tomato purée is a kitchen staple, serving as the base for countless sauces, soups, and stews. While store-bought jars offer convenience, nothing compares to the vibrant flavor and rich texture of homemade tomato purée. This comprehensive guide will walk you through the process from selecting the right tomatoes to storing and using your purée year-round.
What Is Tomato Purée?
Tomato purée is a thick liquid made by cooking and straining tomatoes. It sits between tomato paste (which is highly concentrated and thick) and tomato sauce (which is thinner and often seasoned) in both texture and flavor. Homemade purée is prized for its fresh, clean tomato taste and can be seasoned or left plain for versatility in different recipes.
Why Make Tomato Purée at Home?
- Superior Flavor: Fresh, ripe tomatoes yield a purée that is brighter and more complex than most commercial options.
- Customizable: You control the ingredients, texture, and seasoning according to your desired application.
- Preservation: Making purée at home allows you to preserve the flavor of peak-season tomatoes for use throughout the year.
- Multipurpose: Homemade purée forms the base for sauces, soups, curries, and can even be used in baking.
Choosing the Best Tomatoes
The best results start with ripe, flavorful tomatoes. Opt for varieties known for their rich flavor and low water content:
- Roma (plum)
- San Marzano
- Amish Paste
- Viva Italia
If you can’t find paste-type tomatoes, any very ripe fresh tomato will work. Overripe or slightly blemished tomatoes can also be used as long as they’re not moldy or rotten. Aim for about 3 pounds (1.4 kg) of tomatoes per quart of finished purée.
Essential Equipment
- Sharp paring knife – For coring and scoring tomatoes.
- Large saucepan or stockpot – For cooking tomatoes.
- Slotted spoon – For transferring blanched tomatoes.
- Large bowl of ice water – For shocking tomatoes after blanching.
- Food mill or fine-mesh sieve – For removing skins and seeds.
- Blender or food processor (optional) – For smoother purée.
- Ladle or measuring cup – For transferring purée.
- Clean jars or containers – For storage.
Step-by-Step Guide to Making Tomato Purée
1. Wash and Prepare the Tomatoes
Rinse the tomatoes thoroughly under cool water. Using a paring knife, core each tomato and score a shallow “X” on the bottom. This makes peeling easier after blanching.
2. Blanch the Tomatoes
- Bring a large pot of water to a rolling boil.
- Working in batches, gently lower tomatoes into the boiling water.
- Blanch for 30 to 60 seconds, until skins start to split.
- Quickly transfer tomatoes to a bowl of ice water using a slotted spoon.
3. Peel the Tomatoes
- Once cooled, peel the skin from each tomato (the skin should slip off easily after blanching).
4. Remove Seeds (Optional)
- Cut tomatoes in half horizontally.
- Squeeze gently or use a small spoon to remove seeds if a smoother purée is desired.
5. Cook the Tomatoes
- Place peeled (and seeded) tomatoes in a large saucepan or stockpot.
- Cook over medium heat, stirring occasionally, until tomatoes are very soft and begin to break down (about 10–15 minutes).
This step concentrates flavor and loosens seeds for easier straining.
6. Purée the Tomatoes
- Pass cooked tomatoes through a food mill (or press through a fine-mesh sieve) to remove skins and remaining seeds.
- If a food processor or blender is used, work in batches and process until smooth.
The result is a thick, vibrant tomato purée.
7. Reduce the Purée (Optional but Recommended)
- Return the purée to the saucepan over medium-low heat.
- Simmer, uncovered, stirring occasionally, until the purée thickens to your desired consistency (usually 10–40 minutes).
- This enhances flavor and removes excess water, resulting in a richer product.
8. Season to Taste (Optional)
- Add salt to taste (¼ to ½ teaspoon per quart is typical for a basic purée).
- Optional: Add a pinch of sugar, fresh basil, or garlic to customize your purée for specific dishes.
For most uses, leave the purée unseasoned and season your final dish instead.
9. Cool and Store
- Allow the tomato purée to cool to room temperature.
- Ladle into clean jars, containers, or freezer-safe bags.
- Refrigerate for up to 1 week or freeze for up to 6 months.
- If canning, consult current USDA safety guidelines for acidification and processing times.
Storing and Preserving Tomato Purée
- Refrigerate in airtight containers for up to 1 week.
- Freeze in freezer bags or containers (leave room for expansion) for up to 6 months.
- Canning is possible with acidification (adding bottled lemon juice) and following approved canning protocols.
Label containers with the date and quantity for easy pantry management.

Tips for the Best Tomato Purée
- Use peak-season tomatoes for the sweetest, richest flavor.
- Cook tomatoes briefly before puréeing for an easier texture and improved taste.
- Remove excess water by reducing on the stovetop for a more flavorsome purée.
- Always taste and adjust seasoning just before storing or using.
- Strain through a fine-mesh sieve after blending if an ultra-smooth texture is desired.
Troubleshooting & Frequently Asked Questions (FAQs)
Q: My purée tastes watery. How can I fix it?
A: Simmer the purée uncovered to let excess water evaporate until it thickens and flavor deepens.
Q: Do I have to peel and seed the tomatoes?
A: Peeling and seeding is optional but recommended for smoother texture and milder flavor. If you prefer a rustic purée, blend the cooked tomatoes with skins and seeds, then strain as needed.
Q: Can I use canned tomatoes?
A: Yes, high-quality whole, peeled canned tomatoes can be used when fresh are out of season. Drain excess liquid, then simmer and purée as for fresh tomatoes.
Q: What’s the difference between tomato purée, sauce, and paste?
Purée: Unseasoned, medium-thick, cooked sieved tomatoes.
Sauce: Purée with added seasoning, often thinned, and simmered for longer.
Paste: Highly reduced and concentrated, very thick, intensely flavored.
Q: How do I store homemade tomato purée?
A: Refrigerate and use within a week, freeze for long-term storage, or can following safe processing methods.
Q: How much does homemade purée reduce in volume?
A: Tomatoes lose about one-third to one-half their original volume when cooked and puréed, depending on water content and how thickly you reduce the purée on the stove.
Flavor Variations & Upgrades
- Herbs: Add basil, thyme, or oregano during simmering or after puréeing.
- Garlic or onion: Sweat chopped garlic or onions in olive oil, then add purée for a savory base.
- Heat: Add red pepper flakes for spice.
- Touch of sugar: A pinch of sugar can balance excessive acidity.
Expert Tips for Batch Cooking & Freezing
- Make large batches when tomatoes are cheap and plentiful. Freeze purée in meal-sized portions for future use.
- Fill ice cube trays with purée and freeze, then bag cubes for convenient small portions.
- Always use clean, dry containers to prevent spoilage.
- Label with date and volume. Use oldest batches first.

Frequently Asked Questions (FAQs)
Q: Can I skip the blanching step?
A: Technically, yes. If you blend well and strain thoroughly, skins and seeds can often be removed after cooking, though blanching makes peeling much easier and leads to a silkier purée.
Q: How do I safely can tomato purée?
A: Add 2 tablespoons of bottled lemon juice per quart of purée for acidification. Process jars in a boiling-water bath for the time recommended in official guidelines (typically 35-40 minutes for pints or quarts, altitude-adjusted). Always consult reputable sources for up-to-date canning safety advice.
Q: How do I make a quick tomato purée if I don’t have a food mill?
A: Grate fresh tomatoes with a box grater over a bowl, discarding skins. For cooked applications, blend and strain through a fine sieve.
Q: Is tomato purée gluten-free and vegan?
A: Yes, homemade tomato purée contains only tomatoes (and optional natural seasonings), and is free of gluten, dairy, and animal products.
