Can I Reheat Alfredo Sauce? Tips on Which Method Is Best

Alfredo sauce. One of those hard-to-get-it-perfectly-right foods. Some can be too cheesy, others too buttery, and still others can come out without any real flavor at all, like it’s just thick milk. But when it’s good, it’s amazing, and you want to savor it, which makes it a great leftover dish.

But can you reheat alfredo sauce? And if you can, how? It can be tough to know the right approach to reheating your favorite foods, so it is worth exploring your options.  

Can You Reheat Alfredo Sauce? 

But wait, is it even possible to reheat alfredo sauce?  

Can You Reheat Alfredo Sauce?

The question is a fair one. Creamy sauces, when reheated, can come out burnt or clumpy, completely ruining the dish.  

Fortunately, you can, in fact, reheat any food that has been refrigerated or frozen. The trick lies in knowing how.  

In general, foods that have been grilled or baked typically reheat better in the oven or back on the grill, and foods that have been fried or breaded tend to do better in the oven or in an air fryer.  

Specifically, sauces are often better off reheated on the stovetop. Alfredo sauce is likely no exception.  

Should You Reheat Alfredo Sauce? 

Before you figure out how to reheat alfredo sauce, be sure you know whether you should, in terms of food safety handling and foodborne illnesses.  

Because alfredo sauce is usually just milk and parmesan cheese and butter, you’re probably safe as long as you stored it correctly but do your own research to be sure.  

To get you started, I have linked this article on food safety and reheating by the USDA. 

How to Reheat Alfredo Sauce in the Oven 

Reheating alfredo sauce in the oven will give it that comfort food effect while avoiding worries about overcooking or making it too thick. Just follow these steps: 

  1. Preheat the oven to 350 degrees Fahrenheit.  
  2. Place your sauce in a shallow oven-safe baking dish to ensure thorough warming.  
  3. If you are reheating leftover pasta at the same time, toss your pasta in with the sauce and add a couple tablespoons of milk to mix it together, fully coating your pasta with the sauce.  
  4. Bake the dish uncovered for 15 minutes and check to be sure it is warmed through.  
  5. If necessary, stir your dish and put it back in the oven for another 5 minutes.  

How to Reheat Alfredo Sauce in the Microwave 

The microwave isn’t always your best option for reheating food, but it is a great choice for alfredo sauce. Reheating alfredo sauce in the microwave might even be the best way.  

Follow these instructions for a fast and efficient reheating method:  

  1. Place your sauce in a shallow, microwave-safe dish and cover it loosely with a lid.  
  2. Heat on full power for 30 seconds then stir. Heat again for another 30 seconds and repeat the process until the sauce is heated through. It should not take longer than a couple of minutes at most.  
  3. If you are hoping to add this sauce to leftover pasta, you can flash heat the pasta in a pot of boiling water, so your hot sauce doesn’t get cold as soon as you add it to cold noodles.  

How to Reheat Alfredo Sauce in an Air Fryer 

Okay, now you’re wondering why on earth I would be giving advice about reheating a cream sauce in an air fryer.  

Well, I’m not.

I in fact would not recommend trying to reheat any sauce in an air fryer.  

But I will say that if you add your sauce to noodles, particularly nice, thick, fettucine, or if the sauce is already mixed with noodles, reheating alfredo sauce in an air fryer can be a great way to go. Just know that you will end up with a crispier version than the original.  

  1. Heat your air fryer to 350 degrees Fahrenheit and spray your basket with a no-stick cooking spray.  
  2. Place your sauce-covered noodles in the basket loosely and cook for 3 minutes then check to be sure they are heated through.  
  3. Cook for another 2 minutes if necessary.  

Again, the air fryer is not my first recommendation, or even my second or third. But it will do in a pinch. Think of deep-fried macaroni and cheese balls. This dish will end up kind of like that one.

WINNER – The Best Way to Reheat Alfredo Sauce Is Using the Stovetop 

It really has to be the stovetop for alfredo sauce, though I do love the microwave for this one. And if you are going to use the same dish to eat in as you heated it in, the microwave may be less messy.  

But the stovetop allows you total control, you can watch the sauce the entire time, and get a feel for when it has been returned to its former glory.  

The stovetop wins.
