Alfredo Pasta Storage

When it comes to storing alfredo sauce, it should be frozen immediately.

This will help curb the chance of it separating- which is something that cream-based sauces often do.

Be wary of splitting- that is, the water and fat in the sauce separate, which diminishes the palatability of the sauce and leads to spoilage.

Try storing Alfredo sauce in freezer-safe plastic bags that are resealable and leave an inch at the top to allow for expansion when the sauce freezes.

This should extend the life of sauce for a couple of months.

As for storing the remains of a pasta Alfredo dinner that you enjoyed out at a restaurant, transfer pasta and sauce to an air-tight container and put it in the fridge, preferably near the back where the light and heat from opening the door won’t compromise the cream-based sauce.

Eat the leftovers within five days, though it may stay good for a full week.

Alfredo Sauce and Spoilage

Think about what is in an Alfredo sauce- butter, cream, cheese- and it sounds like it could easily spoil without proper storage conditions.

So, how do you know when your cream-based pasta sauce has turned bad or is on the verge of spoiling?

There are some signs that your sauce is bad and that you should discard it or regret it later, often jeopardizing yourself and increasing the risk for serious illness and food poisoning.

Some signs that your Alfredo sauce has spoiled include the following.

  • Smell

If you enjoy Alfredo pasta regularly, you will probably know if your pasta has been spoiled by the smell of it when you open the container or remove it from the fridge.

The smell of spoiled Alfredo sauce will be pungent, sour, and even tangy, which is a sure sign that it needs to be discarded right away. It could make you seriously ill!

  • Color

Another sign that your pasta sauce is spoiled or unsafe to consume is by examining the color- has the creamy white sauce turned yellow?

If your Alfredo pasta sauce has taken on a yellowish tinge, it is likely that it has turned and should not be used or eaten at all.

  • Taste

So, if the pasta sauce has passed the smell and color test when you open up your leftover Alfredo, give it a taste.

Does it taste a bit sour, like milk that is past its expiration? If the sauce has a sour or foul taste, then throw it out.

Don’t worry- you should not become ill by merely tasting the spoiled sauce- though it may be unpleasant!

Alfredo Sauce Recipe

All this talk about Alfredo pasta sauce- do you know how to make your own?

It is not difficult to make and is really quite an easy and delicious dish to easily prepare at home!

It is based on a cream-based roux, which is when you combine flour and fat to create the foundation for a rich and thick sauce. To make your own Alfredo, follow these steps.

  1. Heat equal parts of flour and salted butter in a pan until it creates a paste and comes together.
  2. Add heavy cream and stir until bubbling. Add a pinch of grated nutmeg, and black pepper (preferably fresh-cracked) to taste when thickened.
  3. Add grated parmesan cheese and finish with fresh or dried parsley.
  4. Toss the sauce with hot cooked pasta until fully coated. Serve immediately with plenty of bread to soak up your delicious sauce! (This sauce also makes a fantastic dip for breadsticks, too!)

Some cooks also add salty bits of ham or bacon to the sauce, or some roasted garlic, for added depth of flavor.
