Tomato sauce is your base here—San Marzano canned if you want to splurge, but any unsweetened variety works. The vinegar matters: apple cider vinegar gives that classic tang (white vinegar if that’s what you’ve got). Whole Foods or Trader Joe’s have great organic options without weird additives. Don’t skip the spices—allspice and cloves are the secret to that complex flavor.

Out of apple cider vinegar? White vinegar or lemon juice at the same amount works fine. Swap white sugar for coconut sugar or maple syrup if you want a less refined sweetener. No onion powder? Fresh minced onion at one-third the amount (but simmer it first to mellow the bite). The spices are flexible—miss one? It’ll still taste great.

This keeps like store-bought—6-12 months in a sealed jar in the fridge. The flavors deepen over time, so it’s actually better after a week. Freeze in ice cube trays for 3 months if you want single-serving portions (thaw before using).

Step-by-Step Instructions for Catsup From Tomato Sauce

This method transforms simple ingredients into a tangy, complex condiment with minimal effort.

Step 1: Combine the Base Ingredients

In a medium saucepan, pour in the 2 cups Tomato Sauce and 0.5 cup Apple Cider Vinegar. I always use smooth, unsweetened tomato sauce here—it provides the perfect blank canvas for building layers of flavor.

Set the pan over medium heat and stir to combine. You’ll notice the mixture begins to simmer gently after 2-3 minutes. This initial heating helps meld the tomato and vinegar together before we add the sweeteners and spices.

Step 2: Add Sweetener and Spices

Reduce the heat to medium-low and stir in the 0.25 cup White Sugar. The sugar balances the acidity of the vinegar and enhances the natural sweetness of the tomato sauce.

Next, add the 1 tbsp Onion Powder, 1 tsp Garlic Powder, 1 tsp Salt, 0.5 tsp Ground Black Pepper, 0.25 tsp Ground Allspice, and 0.125 tsp Ground Cloves. I measure these carefully—ground cloves are potent, and too much can overpower the blend. Stir well to distribute the spices evenly throughout the mixture.

At this point, the sauce should have a deep, rich color and a fragrant aroma as the spices begin to bloom in the warm liquid.

Step 3: Simmer to Thicken

Increase the heat to medium and bring the mixture to a gentle boil. Once boiling, reduce the heat back to medium-low to maintain a steady simmer. You’ll want to cook it for 20-25 minutes, stirring occasionally to prevent sticking.

As it simmers, the sauce will gradually thicken and darken in color. The goal is to reduce it by about one-third—this concentrates the flavors and gives it that classic catsup consistency. You’ll know it’s ready when it coats the back of a spoon and leaves a clear trail when you run your finger through it.

Step 4: Cool and Adjust Seasoning

Remove the saucepan from the heat and let the catsup cool to room temperature. This cooling step is crucial—it allows the flavors to fully meld and the sauce to thicken slightly more as it rests.

Once cooled, give it a taste. Here’s the thing—I like mine with a bit more tang, so I sometimes add an extra splash of apple cider vinegar at this stage. If you prefer it sweeter, you can stir in a bit more white sugar. The beauty of making it this way is that you can adjust it to your personal preference.

Transfer the finished catsup to a clean jar or bottle. It will keep in the refrigerator for up to 2 weeks, though I doubt it’ll last that long once you start using it on everything.

Spicy Options

If you love a little heat with your catsup recipe from tomato sauce, consider adding a dash of Sriracha or hot sauce to the mix. For a homemade twist, blend in finely chopped jalapeños or a pinch of cayenne pepper. Store-bought options like Tabasco or Cholula also pair wonderfully for an extra kick. 🔥

Sweet and Tangy

For a sweeter profile, mix in a splash of honey or maple syrup to balance the tanginess of your tomato-based catsup. Homemade versions can include grated apples or a touch of brown sugar. If you prefer store-bought, Sweet Baby Ray’s BBQ Sauce adds a delightful caramelized depth when swirled in.

Herb-Infused

Elevate your catsup with fresh or dried herbs like basil, oregano, or thyme. A homemade herb blend can be steeped in warm tomato sauce before reducing it into catsup. For convenience, try Italian seasoning from the store—it’s a quick way to add complexity. ✨

Smoky Flavors

Smoked paprika or a dash of liquid smoke can give your catsup a rich, barbecue-like essence. For a store-bought shortcut, Stubb’s Smoky Mesquite Sauce blends seamlessly into tomato-based catsup for a bold, grilling-inspired taste. Perfect for burgers and fries!
