Step 2: Heat the Saucepan
Place your large saucepan over medium heat. Allow it to warm up for a couple of minutes before adding in your ingredients.
Step 3: Add Tomato Paste
Spoon in the 4 oz of tomato paste. Stir it into the pan, letting it heat for a minute or so. This helps to release the flavors.

Notes on Ingredients
Using high-quality tomato paste makes a significant difference in flavor. You can opt for organic varieties if you prefer. The sugar helps to counteract the acidity of the tomatoes, resulting in a more balanced sauce. If you’re looking for a richer flavor, consider adding a splash of red wine or a spoonful of balsamic vinegar.
Storing, Freezing & Reheating
The thickened spaghetti sauce can be stored in an airtight container in the refrigerator for up to 5 days. For longer storage, freeze the sauce in a freezer-safe container for up to 3 months. To reheat, simply thaw in the refrigerator overnight, then warm on the stove over low heat, stirring frequently until heated through.
Frequently Asked Questions
Can I use fresh tomatoes instead of tomato paste?
Yes, fresh tomatoes can be used, but they will require additional cooking time to break down and thicken. You may also need to add more seasoning to balance the flavor.
What if my spaghetti sauce is still too thin after thickening?
If your sauce remains too thin, continue to simmer it uncovered for a longer period. This allows more moisture to evaporate, thickening the sauce further.
Can I add vegetables to my spaghetti sauce?
Absolutely! Onions, bell peppers, and mushrooms can be sautéed before adding the tomato paste for added flavor and texture.
Is this spaghetti sauce recipe suitable for canning?
This recipe is not designed for canning. If you wish to can your sauce, follow proper canning guidelines and use a tested recipe for safety.
