Side Dish 🥗 American Gluten-FreeVegetarian 🥦Vegan 🌱

Homemade Ketchup delivers a rich, tangy-sweet bite with a hint of warm spice from clove, mustard, and cayenne. Slow-cooked tomatoes reduce to a thick, velvety texture that’s perfect for dipping, spreading, or topping burgers and fries. Serve it at cookouts or keep on hand to elevate weeknight meals with a bright, balanced tomato punch.

Homemade Ketchup
  1. 1

    Pour the crushed tomatoes into the slow cooker. Rinse each emptied can with 1/4 cup water and add that to the slow cooker. Add the sugar, vinegar, onion powder, garlic powder, salt, celery salt, mustard powder, black pepper, cayenne pepper, and whole clove; whisk to combine.

  2. 2

    Cook on High, uncovered, until the mixture is reduced by half and very thick, 10 to 12 hours, stirring about every hour.

  3. 3

    Blend with an immersion blender for about 20 seconds to smooth the ketchup's texture.

  4. 4

    Ladle the ketchup into a fine strainer and press it with the back of the ladle to remove any skins and seeds.

  5. 5

    Transfer the strained ketchup to a bowl. Let it cool completely.
