Cottage Cheese Tzatziki vs. Greek Yogurt Tzatziki vs. Sour Cream Tzatziki (Plus Store-Bought)

• Sour Cream: Super creamy with a mellow tang. Easy to mix, great for a smooth dip or dressing.
• Greek Yogurt: More tangy and thick. Classic Mediterranean flavor with gut-friendly probiotics.
• Cottage Cheese: High in protein, lighter in fat. Blended smooth, it’s a modern twist that fits keto meal prep.
• Store-Bought: Usually includes fillers or preservatives. Homemade tastes fresher and keeps the carbs down.

Ingredients

• Full-fat sour cream: Adds richness and smooth texture.
• English cucumber: Mild and crisp—perfect for tzatziki.
• Fresh dill: The essential herb for that vibrant flavor.
• Fresh garlic: For a bold Mediterranean kick.
• Lemon juice: Brightens and balances the creamy base.
• Extra virgin olive oil: Adds flavor and smooth mouthfeel.
• Salt and black pepper: To bring everything together.

Instructions

• Grate the English cucumber using a box grater with large holes.
• Wrap the grated cucumber in paper towels or a clean kitchen towel or cheesecloth and squeeze out as much excess moisture as possible.
• In a medium mixing bowl, combine full-fat sour cream, lemon juice, grated cucumber, olive oil, fresh dill, minced garlic, salt, and pepper.
• Mix well until fully combined and creamy.
• Taste and adjust the seasoning or lemon juice if needed.
• Chill in an airtight container for at least 30 minutes to let the flavors develop.

Expert Tips

• Grate or chop cucumber: Grating gives a traditional texture, but small cubes work too!
• Let it sit: The tzatziki tastes best on the second day once the flavors meld.
• Add cucumber juice: For a thinner dressing, mix in some of the squeezed cucumber juice—or skip squeezing!
• Use fresh herbs: Fresh dill and mint boost flavor and bring out the Mediterranean vibes.
• Avoid watery sauce: Always remove excess water for the creamiest texture.
• Use full-fat sour cream for the creamiest, most satisfying dip.
• Serving Size Tip: This recipe makes about 1 cup (16 tablespoons) of creamy tzatziki. You can portion it into 2 large servings (8 tbsp) or 4 smaller servings (4 tbsp) – perfect for wraps, salads, or dipping fresh veggies.

Ingredient Swaps

• Greek yogurt: Sub sour cream with full-fat Greek yogurt for a classic taste.
• Fresh mint: Add or sub dill for a new burst of flavor.
• Coconut yogurt: For dairy-free needs, unsweetened coconut yogurt is a great option.
• Garlic powder: Works in a pinch if you don’t have fresh garlic.
