The other day, I ran out of sour cream… But I had a container of cottage cheese on hand. So, I thought, let’s give this a whirl (quite literally). The result? With a splash of milk (you could also use water), a little lemon juice (or vinegar), and a pinch of salt, you’ve got a creamy dupe for sour cream that’s almost impossible to distinguish from the real thing!
Use it to top baked potatoes, stir into soups and stews, dollop onto tacos, or fold into dips and dressings. It’s a clever kitchen hack that delivers all the flavor with none of the additives! Plus, it’s budget-friendly and high-protein!
Tip: Be sure to blend until completely smooth for the best texture. The mixture will thicken slightly as it chills, making it perfect for all your sour cream needs.

- Cottage cheese – This forms the creamy base of the sauce. Use full-fat cottage cheese for the richest flavor and creamiest texture, though low-fat varieties also work well. Small-curd cottage cheese blends more smoothly than large-curd options.
- Lemon juice – Provides the tangy acidity that mimics traditional sour cream’s signature flavor. Freshly squeezed lemon juice offers the brightest taste, but bottled lemon juice works in a pinch. You can also use a splash of white vinegar.
- Milk – Helps achieve the perfect consistency and smoothness. Whole milk will give you the creamiest result, but you can use any milk you have on hand. Add a little extra for a thinner consistency if desired. No milk? You can also use water.
- Salt – A small pinch enhances all the flavors and helps balance the tanginess of the lemon.
How to make it

Step 1
Blend the ingredients
- Combine the cottage cheese, lemon juice, milk, and salt in a food processor or high-speed blender.
- Process until the mixture is completely smooth and creamy, scraping down the sides as needed. This typically takes about 1-2 minutes depending on your equipment.

Step 2
Adjust and chill
- Taste and adjust seasoning if needed, adding more salt or lemon juice to suit your preferences.
- Transfer to a container and refrigerate for at least 30 minutes. This allows the flavors to meld and the mixture to thicken slightly.
Ways To Use Homemade Sour Cream Beyond Topping
This cottage cheese sour cream is incredibly versatile! Use it as a topping for baked potatoes, tacos, and chili, or stir it into soups and stews for extra creaminess. It also works beautifully in dips, salad dressings, and baked goods. Try it in creamy pasta sauces or as a base for ranch dressing, or dollop it onto grain bowls and roasted vegetables for a tangy finish.
Don’t toss any leftover liquid from the cottage cheese! You can use it to thin out the sour cream if it becomes too thick after chilling.
Tips and tricks
- Always blend until completely smooth. The texture will be gritty if you don’t blend long enough. Stop and scrape down the sides of the processor or blender halfway through to ensure everything gets incorporated.
- Adjust the consistency to your liking. Add more milk for a thinner, more pourable sour cream, or use less milk for a thicker version perfect for dipping.
- Chill the sour cream for at least 30 minutes before serving. Chilling allows the flavors to meld and helps the mixture firm up to a more sour cream-like consistency.
- Taste and adjust seasonings. After blending, taste the mixture and adjust the salt or lemon juice as needed. You want it to be tangy and well-seasoned.
- Make a larger batch by simply doubling or trippling the ingredients. The sour cream keeps well in the refrigerator for up to 5 days.

Serving suggestions
This creamy sour cream substitute is a versatile favorite for topping, dolloping, and mixing. It’s a fantastic match for all sorts of dishes, including:
- Baked potatoes with chives and bacon
- Chili and hearty soups
- Pierogi and potato pancakes
- Salads as a dressing base
- Dips like onion dip or beef enchilada dip
Storing
- Store leftover sour cream in an airtight container in the refrigerator for up to 5 days. The mixture may thicken slightly as it chills, which is normal. Give it a good stir before serving, and if it’s too thick, whisk in a splash of milk to achieve the desired consistency.
- I don’t recommend freezing this sour cream as the freezing and thawing can alter the smooth and creamy texture, causing it to separate or become watery.
