How to Prepare Garlic Butter Salmon Pasta

Step 1: Cook Your Pasta

Bring a large pot of salted water to a boil. Add the spaghetti and cook according to package directions until al dente—usually around 8-10 minutes. Reserve about 1/2 cup of pasta water before draining. This starchy water will help loosen the sauce later if needed.

Step 2: Sear the Salmon

While the pasta cooks, heat a large skillet over medium heat. Add 1 tablespoon of butter. Season the salmon fillets with salt and pepper. Place them skin-side down in the pan and cook for about 4-5 minutes without moving them to get a nice crisp skin. Flip and cook an additional 3-4 minutes until the salmon is cooked through but still moist inside. Remove the salmon from the pan, let it rest for a minute, then flake it into large chunks.

Step 3: Make the Garlic Butter Sauce

In the same skillet, lower the heat to medium-low and add the remaining 2 tablespoons of butter. Add the minced garlic and sauté for about 1-2 minutes until fragrant but not browned. Stir in the red pepper flakes and lemon juice, scraping up any flavorful browned bits left from the salmon.

Step 4: Combine Pasta and Sauce

Add the drained pasta to the skillet with the garlic butter sauce. Toss to coat evenly. If the sauce seems too thick, add a splash of reserved pasta water to loosen it up. Gently fold in the flaked salmon and fresh parsley. Taste and adjust seasoning with salt and pepper as needed.

Step 5: Serve and Garnish

Serve immediately, topped with a sprinkle of grated Parmesan cheese if you like. A fresh wedge of lemon on the side adds an extra zing for those who want it.

Allergy-Friendly Substitutes

If you’re avoiding dairy, swap the butter for olive oil or a dairy-free butter alternative.
Use gluten-free pasta to accommodate gluten sensitivities.
For a garlic-free option, infuse the butter with herbs like rosemary or thyme instead.
If Parmesan cheese isn’t suitable, nutritional yeast is a great vegan-friendly alternative.

What I Learned Testing

Cooking salmon skin-side down first ensures crispy skin and prevents the fish from sticking to the pan.
Using fresh garlic rather than garlic powder makes a noticeable difference in flavor depth.
Reserving pasta water is essential to getting the sauce consistency just right without making it too runny or dry.
Adding lemon juice at the end brightens the dish and cuts through the richness perfectly.

Freezer-Friendly Notes

This Garlic Butter Salmon Pasta is best enjoyed fresh since pasta texture and salmon quality can suffer from freezing. However, you can freeze the cooked salmon separately in an airtight container for up to 2 months. When ready to use, thaw overnight in the fridge and gently reheat in a skillet with a little butter or olive oil. Cook the pasta fresh and toss with the reheated salmon and sauce for the best experience.

Handy Q&A

Can I use frozen salmon fillets for this recipe?

Absolutely! Just thaw the salmon completely before cooking to ensure even cooking and the best texture.

What’s the best pasta to use for Garlic Butter Salmon Pasta?

Spaghetti is classic and works beautifully, but linguine or fettuccine also pair wonderfully with the buttery sauce. Short pasta like penne can work if you prefer.

Can I make this recipe dairy-free?

Yes! Replace the butter with olive oil or a plant-based butter substitute, and skip the Parmesan or use a dairy-free alternative like nutritional yeast.

How can I add more vegetables to this dish?

Consider tossing in steamed asparagus tips, sautéed spinach, or cherry tomatoes when combining the pasta and sauce for extra color and nutrition.
