Ingredients
The Salmon Base
- 25.0 oz (708g) salmon fillets, skin-on or off
- 2.0 tbsp (30ml) coconut oil, melted
- 1.0 tbsp (15g / 0.53 oz) tandoori seasoning (ensure no added sugar)
The Cooling Cucumber Sauce
- 0.5 (150g / 5.3 oz) cucumber, shredded and drained
- 1.25 cups (285g / 10.1 oz) sour cream (full-fat for keto)
- 2.0 cloves (6g / 0.21 oz) garlic, minced
- 0.5 (15ml / 0.5 fl oz) lime, juiced
- 0.1 tsp (0.5g / 0.02 oz) sea salt (to taste)
The Crispy Salad Bed
- 3.5 oz (100g) lettuce, chopped
- 3.0 (45g / 1.59 oz) scallions, sliced
- 2.0 (300g / 10.6 oz) avocados, diced
- 1.0 (150g / 5.3 oz) yellow bell pepper, diced
- 1.0 (30ml / 1 fl oz) lime, juiced
Step-by-Step Directions
- Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper for easy cleanup.
- In a small bowl, whisk together 2.0 tbsp (30ml) coconut oil and 1.0 tbsp (15g / 0.53 oz) tandoori seasoning until a paste forms.
- Coat the 25.0 oz (708g) of salmon pieces evenly with the spice mixture and place them on the prepared baking sheet.
- Bake the salmon in the center of the oven for 20.0 minutes, or until the internal temperature reaches 145°F (63°C) and the fish flakes easily with a fork.
- While the fish bakes, prepare the cooling sauce by mixing the 0.5 (150g / 5.3 oz) shredded cucumber, 1.25 cups (285g / 10.1 oz) sour cream, 2.0 cloves (6g / 0.21 oz) minced garlic, 0.5 (15ml / 0.5 fl oz) lime juice, and a pinch of salt in a medium bowl.
- Prepare the salad by tossing the 3.5 oz (100g) lettuce, 3.0 (45g / 1.59 oz) sliced scallions, 2.0 (300g / 10.6 oz) diced avocados, and 1.0 (150g / 5.3 oz) diced yellow bell pepper in a large bowl.
- Drizzle the salad with the juice of 1.0 (30ml / 1 fl oz) lime and toss gently to ensure the avocado is coated to prevent browning.
- To serve, portion the crispy salad onto four plates, place one piece of the baked salmon on top, and finish with a generous dollop of the cucumber sauce.

Pro Tips for the Perfect Keto Salmon Tandoori
To ensure your Keto Salmon Tandoori with Cucumber Sauce comes out restaurant-quality every single time, follow these chef-tested tips:
- Pat the Salmon Dry: Before applying the oil and spice mixture, use a paper towel to pat the salmon fillets completely dry. This helps the tandoori spices adhere better and ensures the exterior gets a beautiful "sear" in the oven rather than steaming.
- The "Salt and Squeeze" Method: For the cucumber sauce, after shredding the cucumber, sprinkle it with a pinch of salt and let it sit for 5 minutes. Squeeze out the excess water using a clean kitchen towel. This prevents your sour cream sauce from becoming watery.
- Don't Overbake: Salmon continues to cook for a few minutes after being removed from the oven. Aim for an internal temperature of 140°F (60°C); it will reach the food-safe 145°F (63°C) while resting, keeping the fish moist and buttery.
- Temper Your Sour Cream: Take your sour cream out of the fridge 10 minutes before mixing the sauce. A slightly less chilled base incorporates the lime juice and garlic much more smoothly.
Frequently Asked Questions (FAQ)
Can I substitute Greek yogurt for sour cream in the cucumber sauce? Yes, you can substitute full-fat Greek yogurt for sour cream in this Keto Salmon Tandoori recipe. However, keep in mind that Greek yogurt typically has a slightly higher carb count and a tangier profile. It remains a great keto-friendly option if you prefer a lighter texture.
How do I store and reheat leftovers? Store the salmon and salad separately in airtight containers in the refrigerator for up to 2 days. To reheat, place the salmon in an oven at 300°F (150°C) until just warmed through. Avoid reheating the cucumber sauce or the avocado salad, as they are best served fresh and cold.
Is tandoori seasoning spicy? Tandoori seasoning is generally more aromatic and smoky than "hot." It relies on cumin, coriander, and turmeric. If you prefer more heat in your Keto Salmon Tandoori, you can easily add a 1/4 teaspoon (20 ml / 0.7 fl oz) of cayenne pepper or chili flakes to the oil rub.
Can I make this recipe in an Air Fryer? Absolutely! To air fry, place the seasoned salmon in the basket at 380°F (190°C) for 10–12 minutes. This is a great way to get an even crispier exterior on the fish while keeping the inside tender.
Pro Tips
- Shred the cucumber, salt it for 5 minutes, then squeeze it dry in a kitchen towel — any leftover water will thin out the sour cream sauce.
- Take the sour cream out of the fridge 10 minutes before mixing so the lime juice and garlic blend in smoothly instead of staying grainy.
- Pull the salmon at 140°F (60°C) — it climbs to the food-safe 145°F (63°C) while resting, which keeps the flesh moist instead of chalky.
- Check the tandoori seasoning label for hidden sugar; a clean spice blend keeps this dish solidly keto.
- The salad of avocado, lettuce, scallions, and yellow pepper holds up well for a day, but dress it with lime right before serving so the avocado stays bright.
Frequently Asked Questions
Can I prep any part of keto salmon tandoori ahead?
Yes — make the cucumber sauce and chop the salad vegetables a day ahead and store them separately. Roast the salmon fresh so the spice crust stays lively.
How long does the cucumber sauce keep?
It keeps in the fridge for up to 3 days in a sealed jar. Give it a stir before serving, as a little liquid may separate.
Can I use dried tandoori spices instead of a blend?
A pre-mixed tandoori seasoning is simplest, but any sugar-free chili-garlic-coriander mix will roast onto the salmon the same way in coconut oil.
Is this salmon dish keto-compatible?
Absolutely — each serving has about 6g of net carbs with 73g of fat, so it is a strong keto main. The avocado and full-fat sour cream do the heavy lifting.
