Recently I figured out a hack for thick homemade tomato sauce without hours of cooking. There’s nothing more satisfying than making your own thick, flavorful tomato sauce using the freshest, ripest tomatoes.
Wash and dry your tomatoes. Freeze them whole for 24 hours.
Thaw the frozen tomatoes at room temperature, and drain off the excess water that has been released.
Add the tomatoes to a blender or food processor and blend into a smooth consistency. If you prefer a chunkier sauce, mash them with a potato masher. Then, pass the blended tomatoes through a food mill to remove seeds and skins.
Heat olive oil in a large pot over medium heat. Add garlic and red pepper flakes, and sauté until fragrant. Add the tomato puree, fresh basil leaves, salt, and pepper. Simmer the sauce on medium-low heat for about 30–40 minutes, stirring occasionally, until thickened.
Ladle the sauce into sterilized jars, leaving 1 inch of headspace. Process in a water bath canner for 35–40 minutes.
If not canning, let the sauce cool completely and store in airtight containers in the fridge for up to a week, or freeze for up to 6 months.
