What Does This Recipe Taste Like?

What’s the Difference Between Feta Cucumber Sauce and Tzatziki
Good question! The two are very similar, and we used tzatziki as inspiration for this feta cucumber sauce but added a twist. Unlike tzatziki, this recipe is loaded with protein thanks to the use of both Greek yogurt and cottage cheese. As a result, it is also thicker than tzatziki. We also incorporate a few extra seasonings to make the flavor truly unique.

Ingredients You’ll Need
We use less than 10 ingredients to create this feta cucumber sauce, many of which you probably already have on hand! Here’s everything you’ll need:
- Feta Cheese – This forms the base of the dip. For the best taste and texture, opt for a full-fat block.
- Greek Yogurt – We prefer to use plain, full-fat varieties for an ultra-creamy consistency. If preferred, low-fat options can be used. Just know that the texture of your sauce will vary slightly.
- Cottage Cheese – This is our secret weapon to taking this cucumber sauce to the next level, adding an extra tangy taste and protein while creating a thick texture. Again, full-fat varieties work best.
- Cucumber – Use a large English cucumber.
- Herbs and Spices – Fresh dill, garlic, dried mint, salt, and pepper combine to create savory, refreshing flavors. It’s technically optional, but we also like to include za’atar as a garnish to make this recipe ten times better than anything you’ll find in the store.
- Lemon Juice

Making your own sauces at home doesn’t get easier than this! Just combine everything together, and it’s ready to use. Here’s what to do:
- Combine. Add the feta, yogurt, cottage cheese, garlic, lemon juice, dill, and mint to the bowl of a food processor. Pulse until the ingredients are well combined and creamy.

- Adjust. Give your sauce a taste test, and adjust the seasonings as necessary to satisfy your tastebuds. Garnish with za’atar, if desired, and enjoy!
