Can You Microwave Sour Cream?

Sour cream is one of the foods that people put on everything as a topping – even the saltiest dishes. It is also a common ingredient for various baking recipes, soups, even salads. In fact, we cannot think of a dish that would taste bad with some sour cream on top. Can you?

While sour cream is a food of endless possibilities, it is also not as easy to handle as you think. At least, heating it the wrong way can lead to unpleasant results.

With this said, can you microwave sour cream? While we wouldn’t normally microwave sour cream unless it is part of some leftovers, you can safely microwave sour cream as long as it comes fresh from the package. All you need to know are several small steps that would prevent the cream from separating or curdling.

In the following guide, we will discuss the whole process of microwaving sour cream together with several additional tips and rules we recommend following.

Sour cream is similar in consistency, appearance, and taste to yogurt. It is salty rather than sweet, although its taste is considered to be neutral. Normally, it is sold in buckets with foil on top but you can generally find fresh sour cream in the more specialized stores.

The different types of sour cream have different fat content, which determines the density. Sour cream is obtained by fermentation with bacteria, just as yogurt is made. The existence of these bacteria is what makes the heating process slightly complicated.

When exposed to high temperatures, the bacteria in sour cream or any type of dairy product dies.

Yes, you can microwave sour cream, but you should remember several key subtleties that we will now discuss.

How to Microwave Sour Cream: And Rules to Follow

If we can explain the process of microwaving sour cream with a few words, it would probably be “gently, carefully, and slowly”. Cream, in general, is not the most durable product and you always need to be extra careful with the handling and storage.

Here’s how to microwave sour cream:

Transfer the sour cream from the original container to a microwave-safe container.
Place a paper towel or microwave-safe lid over the container to minimize splattering.
Microwave on high heat in 15-second increments per tablespoon of sour cream. You can also microwave on low heat in 20-second increments per tablespoon of sour cream.
If you’re microwaving large amounts of sour cream, divide the sour cream into smaller portions and heat them individually before transferring the warm sour cream to a larger bowl or container to serve.

To make the explanation easier, we have divided all aspects of microwaving sour cream into our own “rules” which are listed below.

Follow these steps and we can promise you that you will avoid all potential problems.

1. Never microwave sour cream in the original container

While this is an obvious fact for those of us who handle the kitchen at home, it is also a common mistake among people.

It refers to all sorts of food with exceptions being containers that have a sign that approves microwaving. However, we would be surprised if you ever find a sour cream with such a sign on the package.

Why should you transfer your sour cream to a plate or any other microwave-safe dish? When heated in a microwave, the chemicals used to make plastic are released from the container.

The chemicals contaminate the sour cream and make it dangerous for us to eat.

2. Never reheat sour cream that has been heated previously

As previously explained, the bacteria used to make sour cream which is the reason why it tastes and holds this way dies depending on the temperature. Once you heat your sour cream, you cannot reheat it later.

In other words, you should only heat sour cream that is brand new from the packaging or fresh sour cream from the store.

3. Always microwave sour cream in small portions

Monitoring the entire process of heating sour cream in the microwave is key for the success of the operation. You need to be careful not to overheat it as it will separate or curdle.

Generally, you can heat a large portion of sour cream but we highly recommend spending a couple of additional minutes near the microwave to heat it in smaller batches.

Ramekins are perfect for this purpose. These classic Ramekins are our favorite.

If possible, let the sour cream reach room temperature before you microwave it.

According to experts, you need to microwave at high heat for 15 seconds for every tablespoon or 20 seconds at low heat.

In other words, imagine that you need 6 tablespoons of sour cream. This makes 6×15 seconds or a total of 1 minute and 30 seconds in the microwave.

If you feel like the sour cream is not hot enough after this period, continue heating in 5-second intervals until you reach the desired heat. It sounds like a lot of work, but you really do need to check between each interval.

4. Fat content matters when microwaving sour cream

Back in the day, there weren’t so many types of sour cream. If you plan on microwaving sour cream, consider using only full-fat or low-fat sorts.

This is because non-fat sour creams do not hold well under high temperatures. Out of all the types, non-fat sour cream separates and curdles the easiest.

Nevertheless, if you are under a strict diet or simply prefer non-fat products, you can use the microwave. However, we recommend reducing the power to low or at least medium.

Microwaving sour cream on low heat will heat it more slowly but it will decrease the chances of curdling. However, there is no guarantee that it will not happen anyway.
