Introduction
This Low-Carb Homemade Tzatziki Sauce is a creamy, refreshing Greek-inspired dip made with just six ingredients: cucumber, Greek yoghurt, lemon juice, garlic, fresh dill and mint.
Naturally low in carbohydrates when prepared with plain, unsweetened Greek yoghurt, this sauce is a delicious alternative to sugary dressings and dips.
The thick Greek yoghurt provides protein and calcium, while grated cucumber adds freshness and a light, crisp texture. Garlic, lemon juice and fresh herbs create a tangy, aromatic flavour without added sugar.
Perfect for low-carb lunches, keto-style meals and Mediterranean-inspired dinners, this versatile tzatziki pairs beautifully with grilled chicken, fish, roasted vegetables and fresh vegetable sticks.
Why This Tzatziki Is Low in Carbohydrates
The recipe uses ingredients that are naturally relatively low in carbohydrates:
Greek yoghurt (227g): Provides protein and calcium. Choose plain, unsweetened yoghurt to avoid added sugar.
Cucumber (60g): Adds freshness and moisture with very few carbohydrates.
Lemon juice (1 tbsp): Provides acidity and a small amount of vitamin C.
Garlic (1 clove): Adds savoury flavour with a minimal carbohydrate contribution.
Fresh dill (1 tbsp): Provides aromatic flavour without significant carbohydrates.
Fresh mint (1 tbsp): Adds a refreshing herbal note with negligible carbohydrates.
Greek yoghurt contains naturally occurring lactose, so the sauce is low-carb rather than carbohydrate-free. The exact carbohydrate content depends on the yoghurt brand and serving size.
Nutritional Benefits
Protein-Rich: Greek yoghurt provides protein that supports normal muscle maintenance and helps make the dip satisfying.
Source of Calcium: Greek yoghurt contributes calcium for healthy bones and teeth.
No Added Sugar: The recipe contains no added sweeteners, making it a useful alternative to many commercial sauces.
Low in Carbohydrates: Cucumber, garlic, lemon and fresh herbs contribute relatively small amounts of carbohydrates.
Fresh, Simple Ingredients: The combination of yoghurt, cucumber and herbs creates plenty of flavour without requiring starch-based thickeners.
Adaptable Fat Content: Full-fat Greek yoghurt provides a richer texture, while lower-fat varieties can help reduce saturated fat intake.
Best Low-Carb Serving Suggestions
Grilled chicken: Use as a creamy sauce for chicken breast or chicken skewers.
Salmon or white fish: Pair with grilled or baked fish for a refreshing contrast.
Cucumber and celery sticks: Serve as a low-carb vegetable dip.

Roasted courgette: Spoon over warm roasted courgette or aubergine.
Low-carb bowls: Combine with grilled meat, leafy greens and avocado.
Tips for the Best Low-Carb Tzatziki
Choose plain, unsweetened Greek yoghurt and check the carbohydrate content on the label.
Squeeze excess water from the grated cucumber to prevent a watery sauce.
Use fresh garlic for the strongest flavour.
Add fresh dill and mint for a refreshing herbal finish.
Adjust the lemon juice to suit your preferred level of tanginess.
Avoid sweetened yoghurt or dressings containing added sugar.
Use full-fat Greek yoghurt if it fits your dietary preferences, or lower-fat yoghurt to reduce saturated fat.
Refrigerate in an airtight container at 5°C or below.
For best quality, consume within approximately 2–3 days, without exceeding the yoghurt's use-by date.
Is Tzatziki Suitable for a Low-Carb or Keto Diet?
Yes. Homemade tzatziki can fit into a low-carbohydrate diet, particularly when made with plain Greek yoghurt and fresh ingredients.
It contains no flour, starch or added sugar.
However, Greek yoghurt naturally contains lactose, which contributes carbohydrates.
For a strict ketogenic diet, check the yoghurt's nutrition label and account for the portion consumed.
The sauce also contains dairy, so it is not suitable for a dairy-free or vegan diet.

This Low-Carb Homemade Tzatziki Sauce is a simple, refreshing and versatile addition to everyday meals.

Serve it with grilled proteins, fresh vegetables or low-carb wraps for a delicious accompaniment that fits easily into a balanced, carbohydrate-conscious eating pattern.
