How to Make Homemade Spaghetti Sauce with Fresh Tomatoes
Prepare the Tomatoes
Bring a large pot of water to a boil. Score a shallow “X” in the bottom of each tomato. Boil the tomatoes for 30 to 45 seconds, then immediately transfer them to ice water. Once cool enough to handle, peel away the skins, remove the cores, and roughly chop the tomatoes. This process helps to easily remove the skins, resulting in a smoother sauce.
Cook the Aromatics
Heat the olive oil in a large Dutch oven over medium heat. Add the onion and cook for 6 to 8 minutes, stirring occasionally until softened and translucent. Add the garlic and cook for another 30 seconds, just until fragrant. Cooking the aromatics properly builds a flavorful base for the sauce.
Add Tomato Paste
Stir in the tomato paste and cook for 2 minutes, stirring constantly until it darkens slightly and becomes fragrant. This step enhances the sauce’s depth and richness, contributing to its overall flavor.
Build the Sauce
Add the chopped tomatoes, broth, Italian seasoning, oregano, dried basil, salt, black pepper, and crushed red pepper flakes if using. Stir well to combine. This mixture is where all the flavors come together, creating the heart of the sauce.
Simmer
Bring the sauce to a gentle simmer. Reduce the heat to low and cook uncovered for 60 to 75 minutes, stirring every 10 to 15 minutes. The sauce should reduce noticeably and become thick enough to coat the back of a spoon. This slow cooking allows the flavors to concentrate and develop.
Blend (Optional)
For a smooth spaghetti sauce, use an immersion blender directly in the pot or carefully transfer the sauce to a blender in batches. For a rustic sauce, leave it chunky. Blending is optional based on your texture preference.
Finish the Sauce
Stir in the fresh basil. If desired, add the butter for extra richness and the balsamic vinegar for added depth. Taste the sauce and add the sugar only if the tomatoes are noticeably acidic. This final step enhances the flavor and balances the acidity.
Serve
Serve immediately over hot cooked spaghetti with freshly grated Parmesan cheese and additional basil if desired. Serving it hot ensures the best flavor and texture.
Tips for Success
- Use the ripest tomatoes available for the sweetest flavor.
- Simmer uncovered so excess moisture evaporates naturally.
- Stir occasionally to prevent the sauce from sticking to the bottom of the pot.
- Blend only if you prefer a smoother sauce.
- Fresh basil should be added near the end to preserve its bright flavor.
Storage, Freezing, and Make-Ahead Instructions
Allow the sauce to cool completely before storing. Refrigerate in airtight containers for up to 5 days. Freeze in freezer-safe containers or freezer bags for up to 3 months, leaving about 1 inch (2.5 cm) of headspace for expansion. Thaw overnight in the refrigerator before reheating. Reheat gently over medium-low heat, stirring occasionally until heated through. Add a splash of broth or water if the sauce has thickened during storage. The sauce can be prepared one or two days ahead, and many people find the flavor improves after resting overnight in the refrigerator.
FAQ
Can I leave the tomato skins on?
You can, but removing the skins creates a smoother sauce with a more traditional texture.
Which tomatoes are best for homemade spaghetti sauce?
Roma and plum tomatoes are preferred because they contain less water and produce a naturally thicker sauce.
Can I freeze homemade spaghetti sauce?
Yes. Freeze cooled sauce in airtight containers for up to 3 months.
Why is my sauce watery?
Fresh tomatoes vary in moisture content. Continue simmering uncovered until the sauce reaches your preferred consistency.
Can I add meat?
