A tangy, lightly sweet, from-scratch ketchup with pantry staples that’s perfect for fries, burgers, and meatloaf.
By Matt Campbell
I love a condiment that shows up and does the most. This Homemade Ketchup is tangy, cozy, and just sweet enough, with a little zip from vinegar and warm spices. It tastes like ketchup, but fresher, brighter, and more like something you actually cooked on purpose.
No drama. You simmer, you blend, you taste as you go, and suddenly your fries have something to talk about.
Let the ketchup cool completely, then store in an airtight jar or container.
Heads up: This is a refrigerator ketchup. If you want shelf-stable canning, use a tested canning recipe designed for safe acidity levels.
You can, but it will taste sharper and more acidic. If you want “no sugar added,” try swapping in 1 to 2 teaspoons grated apple or a splash of unsweetened apple juice and taste from there. You can also simply reduce the sweetener and let the tomato shine.
Two common fixes: simmer it longer (it helps the sharp edge relax) and add sweetness in tiny amounts (like 1 teaspoon at a time). A small pinch of salt also helps round the edges. Note: this is a flavor fix, not a preservation trick.
Blend it thoroughly, then push it through a fine-mesh sieve. That extra step is the difference between “homemade rustic” and “squeeze-bottle smooth.”
You can, but it becomes a longer project. You will need to cook down peeled, chopped tomatoes until thick, then season and blend. Tomato paste keeps this recipe fast and consistent.
Simmer uncovered a bit longer, stirring often near the end. Ketchup thickens more as it cools, so give it 10 to 15 minutes off heat before you decide it needs more time.
I started making ketchup at home the same way a lot of “extra” kitchen ideas start: I had tomato paste, I had fries, and I thought, I wonder if I can pull this off in one pot. Turns out, yes. And now it is one of my favorite little flexes, because it tastes familiar but better, and you can tune it to your house. More tang? Done. More smoky? Easy. Spicier? Absolutely.
Whisk the base. In a medium saucepan, whisk together the tomato paste and water until smooth. Add the vinegar, brown sugar, salt, onion powder, garlic powder, smoked paprika (if using), allspice, black pepper, and cayenne (if using).
Simmer. Set the pan over medium heat and bring to a gentle simmer, whisking occasionally. Reduce heat to low and simmer uncovered for 20 to 25 minutes, stirring more often toward the end so it does not stick or scorch. If it starts popping, lower the heat a touch or use a splatter screen.
Blend until silky. Take the pan off the heat. Blend with an immersion blender right in the pot, or carefully transfer to a blender and blend until very smooth.
Blender safety note: If you are using a blender, do not fill it to the top. Blend in batches, vent the lid (or remove the center cap), and cover with a clean towel so steam can escape.
Optional: strain for ultra-smooth ketchup. For squeeze-bottle smoothness, push the ketchup through a fine-mesh sieve into a bowl, then scrape the underside of the sieve to get every last bit.
Taste and adjust. This is the fun part. Add a little more vinegar for tang, a touch more brown sugar for sweetness, or a pinch more salt to make everything pop. If it feels thin, simmer 5 more minutes and remember it thickens as it cools.
Quick benchmark: When it is hot, it can taste a little sharper and a touch sweeter than you want. Once cooled, it rounds out and tastes more “finished.”
Cool and store. Let cool to room temperature, then transfer to a clean jar or container. Refrigerate until cold. It gets even better after a few hours.
