Origin of the Recipe
The keto diet has gained immense popularity in recent years due to its ability to promote weight loss and improve overall health. It focuses on high-fat, moderate-protein, and low-carbohydrate foods. While the keto diet is relatively modern, the use of salmon and butter in dishes is rooted in European and Scandinavian cuisines, where these ingredients are staples for their nutrient-rich properties.
Salmon, often referred to as a “superfood,” is renowned for its rich omega-3 fatty acids, which are great for reducing inflammation and promoting brain and heart health. Asparagus, on the other hand, is a classic vegetable, widely used in Mediterranean diets for its rich vitamin content and antioxidants.
The Healthy Keto Salmon with Asparagus and Lemon Butter Sauce is a modern take on these traditional ingredients, bringing them together in a light and refreshing way, perfect for keto meal planning.
Ingredients and Quantities
For the Salmon & Asparagus:
- 4 salmon fillets (about 6 oz / 170g each, skin-on or skinless)
- 1 lb (450g) fresh asparagus, trimmed
- 2 tbsp olive oil (or avocado oil)
- Salt and black pepper, to taste
- ½ tsp garlic powder
- ½ tsp paprika (optional, for color)
For the Lemon Butter Sauce:
- 3 tbsp unsalted butter (or ghee for dairy-free)
- 2 cloves garlic, minced
- 2 tbsp fresh lemon juice (about 1 lemon)
- 1 tsp lemon zest
- 2 tbsp chicken broth or dry white wine (optional, for thinning the sauce)
- 1 tbsp chopped fresh parsley (for garnish)
- Lemon slices, for serving
Step-by-Step Directions and Preparation Method

Step 1: Prepare the Salmon and Asparagus
Start by preparing the salmon fillets. Pat the fillets dry with paper towels to ensure they sear properly. Season both sides with salt, pepper, garlic powder, and paprika. This combination of spices will enhance the natural flavors of the salmon without overpowering it.
Next, prepare the asparagus. Trim the ends and toss the spears with olive oil, salt, and pepper to ensure they’re evenly coated. This will help them cook to the perfect level of tenderness.
Step 2: Cook the Salmon
Heat 1 tablespoon of olive oil in a large skillet over medium-high heat. Once the oil is hot, place the salmon fillets in the skillet (skin side down if applicable). Let the salmon cook for about 4–5 minutes per side or until the fillets are golden and cooked through. The salmon should flake easily with a fork when done. Remove the salmon from the skillet and set it aside on a plate.
Step 3: Sauté the Asparagus
In the same skillet, add the asparagus. Sauté for about 4–6 minutes, stirring occasionally until the asparagus is tender but still slightly crisp. Remove from the skillet and set it aside with the salmon.
Step 4: Make the Lemon Butter Sauce
Lower the heat to medium and add butter to the same skillet. Let it melt completely, and then add the minced garlic. Cook the garlic for about 30 seconds, or until it becomes fragrant. Add lemon juice, zest, and chicken broth or dry white wine to the skillet. Let the sauce simmer for 1–2 minutes to reduce slightly. Taste and adjust seasoning by adding salt, pepper, or a little more lemon juice if desired.
Step 5: Assemble and Serve
Return the salmon fillets and asparagus to the pan. Spoon the lemon butter sauce over the salmon and asparagus. Sprinkle fresh parsley over the top and garnish with lemon slices. Serve the dish immediately for the best flavor and texture.
Keto Tips & Variations: Keto salmon recipe
This recipe is incredibly versatile, so feel free to make a few tweaks depending on your taste preferences and dietary needs.
Add Creaminess:
For a richer sauce, you can stir in 1 tablespoon of heavy cream after adding the lemon juice and zest. This will give the sauce a creamy texture that complements the flavors of the salmon.
Make It Spicier:
If you prefer a bit of heat, add a pinch of crushed red pepper flakes to the sauce. This small addition will give the dish a subtle kick that pairs wonderfully with the lemon and butter.
Oven Method:
If you prefer to use the oven, you can roast the salmon and asparagus on a sheet pan at 400°F (200°C) for 12–15 minutes. Once everything is cooked, drizzle the lemon butter sauce over the dish before serving.
Net Carbs Per Serving:
Approximately 4–5g net carbs per serving, depending on the size of the asparagus and how much sauce is used. This makes it an excellent choice for anyone on a keto diet!
