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

I know we call it Italian food, but let’s be honest. Spaghetti sauce is as American as apple pie. I have not met an American who does not love spaghetti, especially American children.

It’s just such a great meal, you can enjoy it both in a fancy restaurant and on the couch at home watching television. Yes. It’s just good food.  

But what’s the best way to reheat your leftover spaghetti sauce?  

Can You Reheat Spaghetti Sauce? 

Before we get into reheating directions, is it even possible?  

Can You Reheat Spaghetti Sauce?

Yes. Of course. It’s tomato sauce with herbs and spices. It’s possible. It’s actually quite simple.  

Of all the foods to be reheated, some of them quite tricky, spaghetti sauce might be the easiest.  

While there are some basic ground rules, you can honestly reheat pretty much any food that has been frozen or refrigerated.  

Foods that have been baked or grilled typically do better when reheated in the oven or back on the grill while foods that have been breaded or fried tend to fare better in the oven or in an air fryer.  

But you can reheat it all.  

When it comes to spaghetti sauce, a food that has been prepared on the stovetop, your best bet is likely going to be either the stovetop or the microwave.  

Should You Reheat Spaghetti Sauce? 

The only thing that should give you pause about reheating spaghetti sauce in terms of food safety is if it has meat.  

A meat sauce can be tricky because meat can go bad and cause foodborne illness.  

A tomato sauce that is all plant based is not likely going to cause you any problems unless it has mold on it, in which case why are you trying to reheat it? 

But it is always a good idea to do your own research before reheating your food just to be on the safe side.

How to Reheat Spaghetti Sauce in the Oven 

Reheating spaghetti sauce in the oven can be a great way to fill your house with warmth and the fragrant aroma of a delicious meal.  

Follow these steps to return your spaghetti sauce to its previous tasty glory: 

  1. Preheat your oven to 350 degrees Fahrenheit.  
  2. Place your sauce in a shallow, oven-safe dish.  
  3. Cover the dish with aluminum foil.  
  4. Bake for 20 minutes.  

You don’t have to worry about clumping or thickening. Just check to be sure it is warmed through.  

If you are adding the sauce to noodles, you can either add the noodles before you bake the dish and follow the same instructions, or flash boil your noodles in boiling water before adding them to your sauce.  

How to Reheat Spaghetti Sauce in the Microwave 

The microwave provides a quick and easy option for heating up your spaghetti sauce. 

To reheat your sauce in the microwave, use these steps: 

  1. Place your spaghetti sauce in a microwave-safe dish with a loose cover.  
  2. Heat your sauce on full power in 30 second intervals, stirring in between, until cooked through.  

Remember if you want to add noodles, simply flash heat them in boiling water and add to your warmed sauce. Flash heating will prevent your noodles from cooling your warmed sauce.  

How to Reheat Spaghetti Sauce in an Air Fryer 

Reheating spaghetti sauce in an air fryer will take some creativity.  

Obviously, it’s not a good idea to use an air fryer to reheat a sauce alone.  

And I generally would not even recommend it for a noodle dish, unless of course you want a crispy version of your original dish, in which case, the air fryer can be perfect! 

To create that crispy dish, follow these directions: 

  1. Preheat your air fryer to 350 degrees and spray your air fryer basket with nonstick spray.  
  2. Thoroughly mix your sauce in with noodles then shape your dish into balls. Coat your spaghetti balls lightly in breadcrumbs.  
  3. Place your spaghetti balls into the air fryer and cook for 5 minutes.  
  4. The result will be a moist on the inside crispy on the outside “spaghetti and meatball” dish! 

How to Reheat Spaghetti Sauce on a Grill 

Reheating spaghetti sauce on the grill is obviously not the first option. Or the second.  

Or the third.  

But if it’s all you’ve got to work with, we can make it work.  

  1. Bring your fire to a roar then allow it to simmer down to a steady burn on your coals or bring your grill to 350 degrees Fahrenheit. 
  2. Place your spaghetti sauce in an aluminum dish and cover your grill.  
  3. Stir every few minutes for about 10 minutes or until it is cooked through.  
  4. Serve and enjoy! 

How to Reheat Spaghetti Sauce in a Toaster Oven 

If you’re working with a toaster oven, you’ll treat it like a conventional oven but give it a little more time.  

  1. Preheat your toaster oven to 350 degrees Fahrenheit. 
  2. Place your sauce in a shallow baking dish with a cover. 
  3. Bake your sauce for 20 minutes and check to be sure it is warmed through.  
  4. If necessary, you can bake for another 5 minutes.  

How to Reheat Spaghetti Sauce in a Pan on the Stove 

The stovetop is quick, easy, and gives you control over the process. Get started with these easy steps: 

How To Reheat Spaghetti Sauce in a Pan on the Stove

  1. Heat a sauce pan to medium heat and add your sauce. If your sauce seems a little thick, you can drizzle a thin stream of olive oil into your pan before adding the sauce.  
  2. Adding water will only dilute the flavor, so try to avoid this at all costs.  
  3. Stir the spaghetti sauce continuously over the heat until it comes to a simmer, with gentle bubbles.  
  4. Serve and enjoy! 

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

There really is no better way to heat sauce than on the stovetop.  

Of course, the microwave is faster and easier, but it also requires you to give up control, and it is laborious – all the taking out and putting back in and timing for 30 seconds.  

On the stovetop, you can simply heat, stir, and eat.
