Skip the sodium and sugar in store-bought ketchup. Instead, make your own with this quick and easy tomato ketchup recipe using the slow cooker!

Quick and Easy Homemade Ketchup in a green ramekin on a white plate next to sweet potato fries

I love ketchup, but I don’t love getting the bottled stuff from the store. Sure, it’s delicious… but it’s also packed with high-fructose corn syrup and preservatives.

That’s why I like to make this quick and easy tomato ketchup right at home! It’s so simple, and the recipe comes together right in the slow cooker.

And it tastes so much better than the store-bought stuff! Even non-ketchup eaters love this zesty, slightly-spicy, low-sodium version.

If you ask me, the red pepper flakes give it just the right amount of kick. You can even spice it up by replacing the apple cider vinegar with jalapeño white balsamic! Or you could omit the flakes if you don’t want it to be spicy at all.

Feel free to have some fun with this homemade ketchup recipe. That’s the beauty of making it yourself!

How to make quick and easy tomato ketchup

Ready to see how easy it is to make ketchup right at home?

Step 1: In a blender or food processor, combine the tomatoes, onion, shallot, vinegar, brown sugar, mustard, allspice, cinnamon, mace, ginger, cloves, and red pepper flakes. Blend until puréed.

Step 2: Pour the mixture into the slow cooker.

Step 3: Cover and cook on HIGH for about 2-1/2 hours. Stir and scrape down the sides every 30 minutes or so.

Step 4: Remove the lid and continue to cook the ketchup on HIGH, stirring and scraping down the sides regularly, for about another hour or until the ketchup is the consistency you want.

Step 5: Season with salt and pepper to taste, stir, then turn off the slow cooker and let the ketchup cool to room temperature in the pot.

Step 6: Scrape into a glass jar for easy storage.

You can serve your ketchup warm, at room temperature, or cold straight from the refrigerator.

What to serve with this condiment

People who love ketchup tend to put it on EVERYTHING! If that’s you, then feel free to keep doing what you’re doing.

Personally, I love the classic ketchup and French Fries. But rather than go through the drive-thru, I just make this ketchup and serve it with my garlic home fries instead. It’s equally tasty, but SO much healthier!

The cinnamon and other pumpkin pie spices also make this condiment the perfect thing to serve with baked sweet potato fries or sweet potato cakes.

However you choose to enjoy your ketchup, you’ll feel so much better knowing that it’s not packed with sugar, salt, high-fructose corn syrup, or preservatives!

Storage

One of my favorite parts about homemade ketchup is that it lasts for up to two months. Just store it in an airtight container in the refrigerator and enjoy whenever you like.

This recipe makes about 6 tablespoons, so if you have several ketchup fans in the house, you may want to make a double or triple batch!

Other easy tomato condiment recipes

I’m a big fan of making my own sauces, condiments, and dressings at home. I can control the ingredients, plus I know they aren’t filled with preservatives!

Here are a few of my favorite recipes to make:
