Sour cream is one of those ingredients I like to keep on hand, even though I don’t reach for it as often as you might expect. Most of the time, I use plain non-fat Greek yogurt instead. It has a similar tangy flavor and creamy texture, plus it’s higher in protein and lower in calories, making it my favorite everyday substitute.
Even so, there are plenty of times when I still want or need sour cream. Whether I’m serving guests, making a recipe where the flavor really shines, or cooking for someone who simply prefers traditional sour cream, it’s always nice to have available. Of course, life happens, and every once in a while I realize I’m out of both sour cream and Greek yogurt. That’s exactly why I started making this easy homemade sour cream.
This easy homemade sour cream comes together with just four simple ingredients and creates a rich, creamy, tangy topping for your favorite meals. While it’s different from traditional cultured sour cream, it’s a quick homemade version that’s perfect when you need sour cream without running to the store.
And if you’re like me and love keeping Greek yogurt on hand, stay tuned! I’ll be sharing my easy Instant Pot Greek Yogurt recipe soon so you can make your own at home and always have another great sour cream alternative ready to go.

Instead of spending money on a container of sour cream you’ll only use once, this recipe comes together in just minutes using ingredients many families already keep on hand.
Pour the heavy whipping cream into a clean mason jar or mixing bowl before adding the distilled white vinegar and fresh lemon juice.
Stir everything together until the mixture is smooth and well combined. The acids immediately begin reacting with the cream, creating the tangy flavor that makes this so similar to traditional sour cream.
After stirring, let the mixture rest at room temperature for about 10 to 15 minutes. This short resting time allows the ingredients to begin working together before chilling.
Next, stir in the fine sea salt. The salt doesn’t just season the mixture—it balances the acidity and enhances the overall flavor.
Cover the jar with a lid and refrigerate for at least two hours. As the mixture chills, it naturally thickens into a rich, creamy consistency. If you have extra time, letting it chill overnight produces an even better texture.
Before serving, give it one final stir. The end result is a super fresh, creamy sour cream that you wouldn’t be even know was a substitute! Your homemade sour cream is now ready for baked potatoes, tacos, chili, nachos, dips, and all of your favorite recipes.

Can I use this anywhere I normally use sour cream?
Yes! This homemade sour cream works well on baked potatoes, tacos, nachos, chili, soups, burrito bowls, and many baked recipes. While it isn’t a cultured sour cream, it provides a similar creamy texture and tangy flavor for everyday cooking.
Can I use bottled lemon juice?
Fresh lemon juice provides the best flavor, but bottled lemon juice will work in a pinch.
Is this the same as traditional sour cream?
No. This is a quick homemade sour cream rather than a cultured sour cream. It was created for those times when you’ve unexpectedly run out of sour cream and need an easy alternative.
Can I make this ahead of time?
Absolutely. In fact, the texture improves after several hours in the refrigerator, making it a great make-ahead option.
Can I substitute Greek yogurt instead?
Yes! Plain non-fat Greek yogurt is one of my favorite sour cream substitutes. I use it regularly, and I’ll soon be sharing my homemade Instant Pot Greek yogurt recipe so you can make your own from scratch.
Storage
Store your homemade sour cream in an airtight container or mason jar in the refrigerator for up to 5 days. Stir before each use, as slight separation is completely normal.
Freezing Instructions
Freezing is not recommended. The dairy may separate as it thaws, resulting in a grainy texture that doesn’t stir back together well. For the best consistency, enjoy this recipe fresh from the refrigerator.
Variations
- More Traditional Tang: Stir in 2 tablespoons cultured buttermilk in place of the lemon juice for a milder, more traditional sour cream flavor.
- Cultured Flavor: Mix in 2 tablespoons plain Greek yogurt with live active cultures for a richer flavor and slightly thicker consistency.
- Extra Thick: Refrigerate overnight before serving for an even creamier texture.
- Milder Flavor: Reduce the lemon juice slightly for a less tangy substitute that’s closer to some store-bought varieties.
