How To Reheat Caramel Sauce [3 Tested Methods]

Caramel sauce will harden in the fridge, but don’t worry it’s easy to get it back to it’s delicious gooey state again!

You can reheat caramel sauce in the microwave or on the stove. To use the microwave, heat in high in 20-second intervals, stirring during each break. To use the stove, place the caramel in a glass bowl above a pot of boiling water, stirring frequently for 5-10 minutes.

Here’s each method in more detail.

Reheating Caramel Sauce In A Microwave

Time: 1 minute
Rating: 9/10

  1. Make sure the caramel is in a microwave-safe bowl.
  2. Set the microwave to high and heat in 20-second intervals, making sure to stir after every 20 seconds.
  3. Add 5 seconds extra on the end if needed.
  4. Let the caramel rest for a few seconds before serving.

The caramel can get very hot very quickly, so giving it a few seconds to cool before serving makes sure no one’s mouth gets burnt!

Results: The microwave is my go-to method for reheating caramel sauce because it’s so quick. Just make sure not to overdo it or you can burn the sauce.

Reheating Caramel Sauce In A Double Boiler

Time: 5-10 minutes
Rating: 9/10

  1. Set up a double boiler or create a makeshift one if you don’t have one.
  2. Bring the water to a boil.
  3. Place the caramel in the top portion of the double boiler and stir as it softens.
  4. Depending on how much caramel you have it will take between 5-10 minutes.

To create a makeshift double boiler, simply place a glass bowl above a saucepan filled with water.

Make sure the bottom of the bowl isn’t too close to the surface of the water (and definitely not touching) and you’re all set.

Results: This method worked great for heating the caramel sauce, it’s just slower than the microwave. I would use it if I had a lot of sauce to reheat because the microwave can get unpredictable then.

Reheating Caramel Sauce By Leaving It In A Warm Place

Time: 10-15 minutes
Rating: 8/10

  1. Find a warm place in your house such as next to a radiator or on top of the oven.
  2. Place the caramel sauce there and wait for it to soften.

I would recommend covering the caramel sauce if you’re using this method to make sure no bugs, dust, or unwanted hands get in there!

Results: If you’re not in a hurry, this method works fine. But I find I’m not great at planning ahead, so often don’t have time to do this.

Caramel Sauce Reheating Tips

Make sure not to boil the caramel sauce while you’re reheating it, because this can mess with the consistency or overcook it.

If you’ve stored the caramel sauce in a plastic squeeze bottle, you can put the bottle straight in some simmering water for a few minutes to soften the sauce.

How To Store Caramel Sauce

To store caramel sauce, transfer it to an airtight container and keep it in the fridge. Depending on the recipe it can last anywhere from 1 week to several months. Check the caramel sauce before eating it for any signs of mold.

If you’ve used the caramel sauce on a cake or dessert you want to keep at room temperature, it will be okay for 2-3 days because of the sugar content. 

You can also freeze caramel sauce in an airtight container for up to 6 months. Defrost it in the fridge overnight before using, and use any thawed caramel sauce within 2 days. If you want to portion the caramel sauce out in the freezer, freeze it in an ice cube tray before transferring the cubes to an airtight container.
