Sour cream is a dairy product similar to yoghurt but is made by fermenting cream instead of milk. From using it as a basic ingredient in your recipes to topping your dishes, sour cream has its value in almost every food item.
While you might prefer to eat it cold, there may be times when you might need to heat or microwave it. You may even wonder if it can be microwaved or not?
The answer is yes. Sour cream can be microwaved, but there’s a great chance of it getting separated or curdled. So there are a few things you need to make sure of before you start heating your cream.
Types of sour cream
Based on the fat content present in it, sour cream can be classified into 3 types.
- Cream containing 18% or more milk fat is considered as full-fat sour cream.

- And lastly, fat-free sour cream that has less than 0.5g fat in one serving.
- The vegan sour cream made up of soy or other non-dairy material
Can Sour Cream be Microwaved?
Since sour cream is made by fermenting dairy cream and contains lactic-acid-producing bacteria, it makes it a bit tricky to heat it. There is a chance that you overheat and the bacteria die resulting in the separating and curdling of your cream.
Despite all this, you can microwave sour cream. But for this, you have to be very careful about the time and amount of sour cream you are heating. Another thing that affects how you heat it is its fat content.
Fat-free sour creams can curdle easily and you have to be very careful while microwaving such types of cream. Full-fat and reduced-fat sour creams, on the other hand, are far easier to heat.
Is It Safe To Eat Warmed Sour Cream?
According to the USDA guidelines on food temperatures, dairy products should be kept cool and returned to the refrigerator within 2 hours or they can get spoiled.
Of course, no one would want even small amounts of sour cream going to waste, which is an absolute delight to your taste buds and the most irresistible component of most foods.

- Sour cream should only be heated once. Do not microwave it if you have heated it before.
- Even after taking all the precautions, there is no guarantee that the cream won’t get separated or curdled.
- Microwave small amounts of cream at a time. Heating large amounts together may cause it to overheat.
- Transfer the contents in a microwave-safe bowl before you heat your sour cream. Microwaving in the same container is not safe as chemicals might leach into the cream and make it poisonous.

What does the Science Say about Heating Sour Cream in a Microwave?
Cultured cream, commonly known as sour cream is a product similar to yoghurt. Yoghurt is made by adding lactic acid producing bacteria in milk whereas to produce sour cream, these bacteria are added to dairy creams.
The process of fermentation is used in the manufacture of sour cream. Dairy cream that contains at least 18% fats is homogenized at low temperatures. And lactic acid producing bacteria such as lactis biovar diacetylactis are added to it. Rennet enzyme is also used to further thicken the cream.
Microorganisms such as lactis biovar diacetylactisare heat sensitive. When exposed to heat, their activity changes.
In simple words, we call that process spoiling of the food they are present in. Sour cream turns yellow when it is excessively heated through flame or microwaves.
