Instructions

Preheat your oven to 250°F (120°C). A well-calibrated oven is essential here—if it’s too hot, the keto salmon will roast instead of slowly confiting.
Prepare the Keto Salmon:
- Rub the salmon fillets with 2 Tbsp of extra virgin olive oil.
- Season evenly with ½ teaspoon salt and ½ teaspoon pepper (or your preferred pre-seasoned blend).
- Slice the two lemons into thick rounds. Arrange these slices on a baking tray lined with parchment paper.
- Place the seasoned salmon on top of the lemon slices (if the skin is left on, ensure it’s facing down).
Oven Cooking: - Place the tray in the oven and cook for approximately 25 minutes. If using thicker fillets, extend cooking by 3 to 5 minutes more until the fish is just opaque and tender.
Prepare the Vegetable Medley: - While the fish cooks, heat 1 tablespoon of cooking oil in a deep saucepan over medium heat.
- Add 1 tablespoon of butter. Once melted, add the thinly sliced carrot and stir-fry for about 1 minute until slightly softened but still crunchy.
- Remove the carrots and set aside in a warm spot.
- In the same pan, add 1 tablespoon minced garlic and sauté for about 20 seconds.
- Add the spinach leaves; stir-fry gently until wilted (season with approximately ½ teaspoon salt and ½ teaspoon pepper). Transfer the spinach to a serving plate.
Make the Lemongrass Sauce: - In a small saucepan, add 1 tablespoon of butter and allow it to melt until lightly bubbling.
- Add the prepared lemongrass pieces, cooking for about 30 seconds to infuse the butter with its aroma.
- Pour in 150 ml fresh cream. Bring the mixture to a gentle rolling boil.
- Stir in 1 teaspoon liquid chicken stock (or ½ cube of bouillon, crumbled) and whisk until well combined.
- Let the sauce simmer for a couple of minutes, until it thickens slightly. Remove and discard the lemongrass pieces.
- Stir in 1 tablespoon of lemon juice and adjust seasoning by tasting.
Plate and Serve:
- Arrange a bed of wilted spinach and sautéed carrots on the plate.
- Place the salmon fillet on top of the vegetable medley.
- Drizzle a generous amount of the lemongrass cream sauce around and over the salmon.
- Garnish with chopped chives and a light drizzle of the remaining olive oil if desired.
