How to Make Keto Lemon Salmon Pasta

Preparing keto salmon pasta with lemon highlights fresh flavors while maintaining a low-carb profile. This protein-rich pasta dish pairs omega-3-rich salmon with low-carb and gluten-free protein pasta noodles and a light lemon butter sauce for an easy keto pasta meal.

Instructions

1. Prepare the Salmon

Pat the salmon dry and season both sides with salt and pepper. In a large skillet over medium heat, add 1 tablespoon of ghee or olive oil. Sear the salmon skin-side down for 4–5 minutes, then flip and cook another 2–3 minutes, or until cooked through. Transfer to a plate and tent with foil.

2. Sauté Aromatics

In the same skillet, add the remaining ghee or olive oil. Sauté the garlic over medium-low heat until fragrant, about 30 seconds.

3. Deglaze and Brighten

Pour in the white wine or vinegar and stir, scraping up any browned bits. Add lemon juice and zest, stirring to combine.

4. Cook the Vegetables

Add the spinach and cook until just wilted, about 1 minute. Toss in the keto-friendly pasta noodles and sauté for 2–3 minutes, just until tender but still firm.

5. Finish and Serve

Flake the cooked salmon into large chunks and return it to the pan, gently combining it with the noodles. Sprinkle with fresh parsley and adjust seasoning with salt and pepper to taste.

6. Plate

Divide the pasta between two bowls and serve warm, garnished with extra lemon zest or a drizzle of olive oil if desired.

Tips & Tricks

1. Use fresh ingredients: Fresh salmon, garlic, and lemons enhance flavor. Opt for coho salmon or smoked salmon for variety.

2. Perfect high-protein pasta noodles: Cook the protein-rich and low-calorie pasta noodles according to instructions, preserving texture for this gluten-free keto pasta.

3. Balance flavors: Combine lemon juice, zest, and garlic in your lemon butter sauce to complement the salmon's richness and make the dish stand out.

4. Use dairy substitutions: Replace ghee or butter with olive oil if creating a dairy-free keto sauce.

Can you make this pasta a cream sauce pasta?

Yes, it’s possible to convert this dish into creamy keto pasta. Using heavy cream or unsweetened almond milk adds creaminess while keeping it low-carb.
