Tomato sauce is a staple ingredient in many households and is used in a wide variety of dishes, including pasta, pizza, and soups.
While store-bought tomato sauce can be convenient, many people prefer making their own at home for the freshest and most flavorful results. However, one question that often arises is how long homemade tomato sauce can last in the fridge before going bad.
In this article, we will explore the factors that affect the shelf life of homemade tomato sauce and provide some tips on how to store it properly to ensure it lasts as long as possible.

How Long Does Homemade Tomato Sauce in the Refrigerator?
The shelf life of homemade tomato sauce in the refrigerator can vary depending on several factors, such as the ingredients used, how it was prepared, and how it’s stored. Generally, homemade tomato sauce can last for around 5-7 days in the refrigerator if stored properly in an airtight container.
However, if the tomato sauce has been left at room temperature for more than 2 hours, it should be discarded, as bacteria can grow rapidly in warm temperatures. Additionally, if you notice any signs of spoilage, such as mold, an off odor or taste, or a change in texture, it’s best to err on the side of caution and discard it.
To extend the shelf life of homemade tomato sauce, you can also freeze it for up to 6 months. Be sure to use freezer-safe containers or bags and leave enough room for the sauce to expand as it freezes. When you’re ready to use it, simply thaw it in the refrigerator overnight and reheat it on the stove or in the microwave.
How to Store Homemade Tomato Sauce
Proper storage is key to extending the shelf life of homemade tomato sauce. Here are some tips for storing tomato sauce:
- Refrigerate it promptly: After making the tomato sauce, let it cool down to room temperature, and then transfer it to an airtight container. Refrigerate it as soon as possible to prevent bacterial growth.
- Use airtight containers: Store tomato sauce in airtight containers or jars to prevent air and moisture from getting in, which can cause spoilage.
- Label and date: Label your containers or jars with the date that the tomato sauce was made so that you can keep track of how long it has been stored in the fridge or freezer.
- Freeze it: If you won’t be using the tomato sauce within a few days, consider freezing it. Freeze the tomato sauce in small portions so that you can defrost only what you need.
- Thaw it safely: To thaw frozen tomato sauce, place it in the refrigerator overnight. You can also thaw it in the microwave or in a saucepan on the stove over low heat.
By following these storage tips, you can help ensure that your homemade tomato sauce stays fresh and safe to eat for as long as possible.

How To Tell If Tomato Sauce is Bad?
There are several signs that homemade tomato sauce has gone bad. Here are some things to look out for:
- Mold: If you see mold growing on the surface of the tomato sauce or inside the container, it’s a clear sign that it has gone bad and should be discarded.
- Off odor: If the tomato sauce has a foul or off odor, it is likely spoiled and should not be consumed.
- Discoloration: If the color of the tomato sauce has changed significantly, such as becoming darker or developing a green tint, it is likely that it has gone bad.
- Texture changes: If the tomato sauce has become thicker or slimy, it is likely that it has gone bad.
- Sour taste: If the tomato sauce has a sour or unpleasant taste, it may be spoiled.
If you notice any of these signs, it’s best to throw away the tomato sauce to avoid the risk of getting sick.
How to Keep Tomatoes Fresh Until You Make Sauce
Tomatoes are a perishable fruit that can spoil quickly if not stored properly. Here are some tips to keep tomatoes from spoiling before you make your homemade sauce.
- Store at room temperature: Tomatoes should be stored at room temperature, ideally between 55-70 °F. Avoid storing tomatoes in direct sunlight or near heat sources, as this can cause them to ripen and spoil more quickly.
- Keep them dry: Moisture can cause tomatoes to spoil faster. To keep them dry, avoid washing them until you’re ready to use them. If you need to wash them before storing, be sure to dry them thoroughly before putting them away.
- Store stem-side down: Storing tomatoes stem-side down can help prevent air and moisture from entering the fruit, which can cause spoilage.
- Use a paper bag: If you need to ripen tomatoes quickly, place them in a paper bag with an apple or a banana. The ethylene gas produced by the apple or banana will accelerate the ripening process.
- Store away from other produce: Some fruits and vegetables, such as bananas, avocados, and apples, release ethylene gas, which can cause tomatoes to ripen and spoil more quickly. Store tomatoes away from these types of produce to extend their shelf life.
By following these tips, you can help extend the shelf life of your tomatoes and prevent them from spoiling too quickly.
