The Art of Homemade, Tomato Sauce

on April 25, 2025

There’s something beautifully nostalgic about the annual tradition of making Italian tomato passata from scratch. For many families, it's more than just preserving tomatoes—it's preserving a way of life. Whether you remember helping Nonna in the backyard or you’re just discovering this ritual, there’s something special about crafting passata yourself. And while everyone has their own setup, one tool remains a staple in Italian kitchens: the trusted pure, food grade, aluminum stock pot.

Tomato Sauce vs Passata

Tomato sauce and passata are both made from tomatoes, but they’re a little different. Passata is simply pureed, strained tomatoes with no seeds or skins—smooth and uncooked. It’s often preserved in jars or bottles, making it perfect to use all year round, especially when fresh tomatoes aren’t in season. It’s thicker than tomato juice but not as concentrated as paste—think of it as the perfect tomato base.

Tomato sauce, on the other hand, is usually cooked and seasoned with herbs, garlic, and onions. To make tomato sauce from passata, just heat it with olive oil, garlic, salt, and your favourite herbs. It’s a quick and easy way to enjoy rich tomato flavour anytime.

Why Make Tomato Passata at Home?

There’s a reason so many people still set aside a weekend in late summer for this timeless process. Homemade passata offers:

  • Unmatched flavor – Ripe tomatoes, gently simmered and pureed, result in a rich, naturally sweet base that store-bought sauces just can’t compete with.

  • Clean ingredients – You know exactly what goes into your passata—no preservatives, no added sugars.

  • A connection to tradition – Making passata is often a family affair, handed down from generation to generation. It brings people together.

  • Year-round convenience – Once jarred or bottled, your homemade passata becomes the foundation for pasta sauces, soups, stews, and more.

Aluminum stock pots are the top choice for making homemade tomato sauce, whether you're whipping up a small family dinner or prepping large batches for canning. Despite the common myth that aluminum alters the taste of tomato sauce or causes a metallic flavor, high-quality, food-grade natural aluminum is completely safe and does not react with acidic foods like tomatoes—especially when the pot is thick and well-constructed like ours.

If you’re making a large batch of tomato sauce—say, over 3 bushels of tomatoes—you’d be crazy to dirty your kitchen! Save yourself the mess (and the stress) by setting up a propane burner outdoors. These heavy-duty burners are built to handle the weight of our large aluminum stock pots, even the massive 64L and up sizes.

Propane burners must only be used outside, as per manufacturer instructions.

  • Your standard home stovetop can’t safely support the size or weight of these large pots—unless you’ve got a full commercial kitchen.
  • Outdoor cooking keeps the heat, steam, and splatter out of your house.
  • It’s faster, cleaner, and gives you more room to work with big batches.

From preparing your tomatoes to bottling the final product, these items will make the job much easier and help ensure your sauce is stored properly for the months ahead. Here's what you’ll need:

  • Tomato milling machine or manual food mill – Crucial for removing skins and seeds, leaving you with a smooth, velvety sauce.
  • Ladle – For safely scooping hot tomatoes or passata from the pot to the mill or jars.
  • Stirring paddle or long-handled spoon – A wooden spoon helps you stir large quantities without burning your hands.
  • Large bowls or containers – To collect and hold the passata before jarring.
  • Clean jars or bottles – Mason jars or traditional passata bottles are ideal for preserving.
  • New lids and rings or bottle caps – Always use new ones to ensure a proper seal and avoid spoilage.

🧑🍳 Step-by-Step: How to Make Homemade Tomato Passata

  1. Wash and sort your tomatoes
    Remove any bruised or damaged ones.
  2. Cut tomatoes in half and remove seeds
  3. Add to pot with a little water
    Place the cut tomatoes into a large aluminum pot with about 1/4 cup of water at the bottom to prevent sticking.
  4. Boil until softened (about 30 minutes)
    Cook the tomatoes until they’re soft and breaking apart.
    🔥 This is where your propane burner and aluminum pot shine—big capacity and fast boiling!
  5. Drain the tomatoes
    Use a strainer or slotted spoon to lift the tomatoes out. Discard the leftover water.
  6. Run tomatoes through a food mill or tomato press
    This removes skins and leftover seeds, leaving you with smooth passata.
  7. Return the strained passata to your pot
    Simmer gently for 30 minutes to 1 hour, stirring occasionally. You want a nice, thick consistency.
  8. Add salt to taste
    This helps preserve the sauce and brings out the flavor.
  9. Sterilize your jars or bottles while the passata simmers
    Make sure they’re clean, sterilized, and still warm when you're ready to fill them.
  10. Fill jars with hot passata
    Use a funnel to avoid spills and leave about ½ inch of space at the top.
  11. Seal and process jars
    Use a water bath or pressure canner to seal jars properly for long-term storage.
  12. Listen for the "pop"!
    You’ll know the jars are sealed when you hear the lid pop down.
  13. ✅ When sealed properly, your homemade passata can be stored in a cool, dark place for up to 1 year.
