Step 1

Melt butter in a medium saucepan over medium heat. Then add grated onion, oregano, salt, and red pepper flakes, stirring occasionally until lightly browned/golden, about 5 minutes. During the last 2 minutes, add minced garlic and stir until fragrant, about 1-2 minutes.

Step 2

Add the tomatoes and sugar if using, stirring to combine. Reduce heat to simmer or low and allow to simmer until the sauce is thick, fragrant and rich in color, about 30 minutes. The sauce should reduce to about 2 ½ cups at this point, if it looks like more, continue simmering until it reduces further. Remove from heat and set aside until ready to use.

Step 3

Spread on pizza crust and build pizza as desired. This pizza sauce works great on deep dish pizzas, thin crust, regular crust, even on french bread or store bought pizza crust. Note: allow to cool 15-20 minutes before using on thinner unbaked crusts, to avoid soggy crusts.

Step 4

If not using sauce immediately, cool completely and store in airtight container or freezer baggie until ready to use. Refrigerated keeps 4-6 days, frozen up to 3 months.
