How Long does Ragu Last in the Fridge?

Whether you’re new to cooking or you’ve been doing it for years, there are some things you should know about how long Ragu lasts in the fridge. Then, when you’re ready to start using it, you can be sure it will taste great. This is especially true for cream-based sauces, which hold up better in the cold.

The meaning of the expiration date on food products is unclear to many people. In addition, “use by” and “sell by” dates may be unclear. The fact is that food safety is not always determined by an item’s expiration date. It is important to remember that products with expiration dates are at their best. The meal might not be at its best if it has passed its expiration date.

The purpose of expiration dates and the shelf life of Ragu will be covered in this blog post. We will also offer some advice on storing food, so it lasts longer properly.

What is a Ragu?

A meat-based sauce known as ragù is frequently used with pasta. Traditionally, pieces of meat (commonly beef, pork, game, or even horse) are braised for a long time over a low fire in a liquid that is typically made of tomatoes or wine.

Numerous ragù recipes are popular throughout Italy; particular provinces, regions, and communes on the island each have their special take on the well-known sauce. Ragù alla Bolognese, a beloved sauce from Bologna in the province of Italy, is undoubtedly the most well-known example of a ragù. Ragù alla Barese, or ragù from Bari, the region’s capital, is likelier to be on the table on a Sunday afternoon in Puglia than in Naples.

How Long does Ragu Last in the Fridge?

A well-liked pasta sauce that is available in most supermarkets is Ragu. Once opened, it has a shelf life of around two weeks. How long does it keep in the refrigerator?

Although it is ideal to use ragu sauce within two days of opening, it can be stored in the refrigerator for up to four weeks (unopened) and three to five days (opened).

An open jar of Ragu will keep for three to five days like any other spaghetti sauce, although some people have reported up to seven days of storage in the refrigerator. Always look at the jar’s “use by” date before purchasing it. Give your sauce a sniff test if you’re unsure how long it’s been open; if it doesn’t smell fresh, it’s time to throw it out.

Is Prego and Ragu the Same?

No, Ragu and Prego are not interchangeable. Ragu is a pasta sauce brand produced by Unilever, whereas Prego is a pasta sauce brand produced by Campbell’s. Prego or Ragu can be a better choice depending on the type of pasta sauce you’re looking for since both brands provide a variety of sauces.

Prego pasta sauces are thinner and have more delicate flavors than Ragu pasta sauces, which are thicker and often have stronger flavors. So, Ragu is certainly a better choice if you’re looking for a sauce to cover your pasta and add lots of flavors to it.

Prego, though, would be a better option if you’re seeking a lighter sauce that won’t overpower your pasta. Ultimately, it all boils down to taste and the type of sauce you’re in the mood. Try both brands and decide which you prefer.

What is the Correct Method of Storing Ragu?

The harvest of tomatoes symbolizes the end of summer in Italy. Families in rural areas, particularly in the south of the nation, spend a couple of days producing passata from their great Pomodoro and then storing it in previously used glass bottles that have been sterilized. You are free to follow suit!

Any airtight container, even Tupperware with a sealable lid, will suffice if you don’t have any additional glass bottles. After you’ve sealed it up, all that’s left to do is put the ragu sauce in the refrigerator. This way, sauces can be preserved in the refrigerator for four to five days.

How to Freeze Ragu?

Ragu sauces are simple to prepare and freeze for later use. Stock up on ready-to-eat ragu sauces and keep them in the freezer. It is always the key to making quick weeknight meals. While reheating your sauce, cook some pasta for a delicious dinner on the fly. Here are some suggestions for freeze, thaw, and reheat ragu sauces. Also, have a look at some of our top ragu sauce recipes.

Before packaging, let your sauce cool fully.

Use a quart-size zip-top plastic bag to freeze the sauce in greater quantities flat on a baking sheet. The baggies can be stacked once frozen to save space.

You can freeze leftover ragu sauce in ice cube trays or greased muffin cups, freeze it, then transfer it to plastic bags if you only have a tiny amount (or want single servings) left. Don’t forget to write the name and the date on each bag’s label.

Most ragu sauces thaw flawlessly in the refrigerator overnight. They can be directly heated in the pan on the stovetop or defrosted and reheated on low in the microwave. Some cream sauces may require a little more whisking to reassemble.

How to Thaw Ragu?

The refrigerator is the safest place to defrost large quantities of ragu sauce. You should be ready to give it plenty of time, though.

Although it takes much longer to defrost in a chilly environment than at room temperature, doing so helps avoid other problems, including high separation levels and bacteria formation.

In other words, try to put it in the fridge the day before and let it sit there till it thaws.

Oh, and another quick tip: place the frozen bags on a plate or in another container because they will leak a lot of water, and you do not want to do further cleanup afterward.

Reheat the ragu sauce on the stove when you’re ready to use it. Grab a pan and increase the heat to medium.

You can adjust the mixture by adding a tablespoon of olive oil or little water. Depending on the heat, reheat for at least 10-15 minutes.

Just a brief reminder: as sauces thaw, they often split, but you shouldn’t be concerned. If you give yourself a minute or two to beat it, it should revert to its original state, or at least mostly original.

How can you Tell Whether Ragu is Spoiled?

If Ragu exhibits any of the traits listed below, he is likely spoiled. In most cases, simply looking at it will reveal whether Ragu has spoiled it. Other times, it could be more difficult to determine if food has gone bad because some bacteria don’t alter how food tastes or appears, but they are still present.

Look at a few indications that Ragu has become spoiled.


Ragu should have a rotten, off-putting scent if it has gone bad. When you open the refrigerator or the container containing it, you can immediately detect the odor because it is so potent.

When you cook food or put it in the refrigerator, the food should still have the same aroma.


Ragu that has been spoiled will have some discoloration, such as black, blue-black, or brown. It might be due to certain chemical interactions, like in the case of apples, or it might be due to bacteria and their toxins.

Ragu that has spoiled nearly always has mold on it—ragu of this kind that has gone bad must be thrown away immediately.


Changes in texture are another sign of spoiled Ragu. Throw the meal out if you see any slimy, sticky, or soggy textures.


If everything else seems to be in order, conduct a taste test. Check to check whether the flavor hasn’t changed or if it does. A changed flavor typically indicates rotten food.

For instance, when cream and yogurt go bad, they taste sour—like milk.


Freezer burn is indicated by frost on top of frozen food. The texture and flavor of food are changed by freezer burn. Frost, therefore, indicates that the food has gone bad.

Gas Bubbles

Food preserved in jars or cans and with gas bubbles that rise to the top is spoiled.

What are the Side Effects of Consuming Expired Ragu?

The manufacturer merely provides the “best before,” “sell by,” and “use by” dates to give you a general idea of how long a specific product will stay in top shape.

Food does not inherently spoil after this point, but it may lose some of its texture or change in flavor.

If you correctly store your food in the refrigerator, it will often keep longer. Food is safe to eat for extended periods at lower temperatures because it stops disease growth.

To extend their shelf life, processed goods have preservatives added to them. Even after their expiration dates, they are still safe to eat.

Be cautious when handling perishables. For instance, it is advisable to discard eggs and dairy products like milk after their expiration dates because they tend to spoil quickly and can lead to food poisoning.

Reference: Carbohydrate-rich breakfast attenuates glycaemic, insulinemia, and ghrelin response to ad libitum lunch relative to morning fasting in lean adults

Participants received an ad libitum lunch test meal consisting of 1 kilogram of cooked (or wet weight) penne pasta from Sainsbury’s with tomato sauce from Ragu, prepared at a ratio of 1:1 uncooked mass three hours after breakfast. In order to determine the energy density for the homogeneous mixture of pasta and sauce, each pasta meal was prepared according to the recommended cooking times, with the energy density of the cooked pasta calculated (to account for any variations in water absorption) and the final masses of pasta and sauce combined noted. 79% of the energy in the lunch was derived from carbohydrates, 14% from fat, and 7% from protein.


The ragu can be kept in the pantry for a few days, unopened. It should be kept in a cool, dry area with low humidity. Additionally, the light should be kept away from it. Preservatives have been added to the product to prevent spoilage at room temperature.

Ragu should be refrigerated after opening to prevent spoiling. After being properly packaged, store it in the refrigerator. Additionally, you can put it in an airtight container for storage. When properly stored in the refrigerator, Ragu only lasts for around 3 to 5 days after being opened.
