Best Substitute For Sour Cream In Casserole

Cottage Cheese

Cottage cheese is an ideal substitute for sour cream in casseroles if you are looking to cut out some fat. Cottage cheese is lower in calories and a much better option than sour cream, but it won’t change the consistency of your delicious casserole.

You can swap one cup of sour cream for one cup of cottage cheese. If you want to make the cottage cheese taste more like sour cream, you can add some lemon juice.



Mayonnaise or vegan mayonnaise can be another great substitute for sour cream in casseroles, as it has the same creamy consistency without the sour taste. If the recipe calls for one cup of sour cream, you can use one cup of mayonnaise.

The moisture content in mayonnaise will also ensure that your casserole turns out creamy, as it won’t cause any of the ingredients to dry out.


Believe it or not, you can use tofu and some pantry staples to create your own substitute for sour cream to add to a casserole dish. Whether you’re vegan, lactose intolerant, or looking for a protein kick in your casserole, tofu can do the job.

You want to throw your tofu in a blender with apple cider vinegar, lemon juice, and salt. You’ll get that nice sour tang that you enjoy from sour cream without an upset stomach. A standard block of tofu will make a few cups of vegan sour cream, so you want to use an equal amount for your recipe as you would for sour cream.
