Garlic and Onion Lovers' Pizza Sauce

Do you love the bold flavors of onions and garlic? If so, this homemade pizza sauce recipe is perfect for you. It is absolutely packed with onions and garlic, both roasted and nonroasted, and made with fresh plum tomatoes for a sensational flavor. Use it to top all of your favorite homemade pizzas—it's a good idea on nights you're feeling like pizza, but don't want to drive to your favorite pizza restaurant. Do plan ahead before making this sauce—it has to simmer for about 2 hours in order to thicken properly.


  • 8 ripe plum tomatoes
  • 2 medium onions
  • 6 cloves of garlic, peeled
  • 1 teaspoon salt
  • 2 tablespoons olive oil
  • ½ teaspoon white sugar
  • 2 tablespoons fresh basil, chopped
  • 2 tablespoons fresh oregano, chopped
  • 1 small, canned roasted red pepper, chopped (optional)
  • ¼ cup water


Bring a large pot of water to a boil on the stove. Drop the tomatoes in for 10 seconds, and then remove them. Let them cool slightly, and then slide the skins off, using your hands. Set the tomatoes aside.

Slice the onions thinly. Spread half of the onions on a baking sheet, and add 4 cloves of garlic (whole) to the pan. Drizzle these with olive oil, and then roast them in a 375-degree oven for 20 minutes. Stir the onions and garlic halfway through the cooking time to prevent them from sticking to the pan.

When the onions and garlic are done roasting, combine the roasted and nonroasted onions and garlic and the tomatoes, water, salt, and sugar in a large pot. Add the roasted red pepper, too, if you so choose. Use a fork or pastry blender to partially mash up the tomatoes. Bring this mixture to a simmer and simmer for 2 hours, stirring often. The tomatoes, onions, and garlic should start breaking down and becoming very mushy. The mixture should seem slightly too thick—it will thin out when you puree it.

After 2 hours of simmering, remove the pan from the stove and use an immersion blender to puree the sauce until it is very smooth. Stir in the basil and oregano, and simmer the sauce for another 15 minutes.

Use about 1 cup of this sauce to top a standard 14-inch pizza. Using more may result in a wet crust. Store any extra sauce in a glass container in the fridge for up to one week or in the freezer for several months.
