Ingredients You’ll Need
Nothing crazy here—just a handful of everyday ingredients that deliver major flavor.
- Salmon fillets – Skin-on works best because it holds the fish together and crisps nicely.
- Fresh asparagus – Snappy, green, and perfect for soaking up lemon butter sauce.
- Butter – Go for unsalted so you control the seasoning.
- Garlic – Freshly minced, not the sad stuff in a jar. Trust me.
- Lemon juice + zest – Fresh is non-negotiable. That zest? It’s flavor gold.
- Salt & pepper – Simple seasoning that makes everything pop.
- Optional extras: Fresh parsley, chili flakes for a kick, or parmesan if you’re feeling fancy.
Pro tip: Don’t skip the zest. It gives that subtle citrus punch without drowning your salmon in lemon juice.
Step-by-Step Instructions
This is where it gets fun (and ridiculously easy).
Step 1: Prep your salmon and asparagus
- Pat the salmon dry with paper towels (this helps with crisping).
- Season both sides generously with salt and pepper.
- Trim the woody ends off your asparagus.
Step 2: Sear the salmon
- Heat a tablespoon of butter in a large skillet over medium-high heat.
- Place salmon fillets skin-side down first. Let them cook undisturbed for 4–5 minutes until the skin gets crispy.
- Flip and cook another 2–3 minutes. Remove salmon from skillet and set aside.
Step 3: Make the lemon butter sauce
- In the same skillet, add the rest of the butter.
- Toss in the garlic and sauté until fragrant (about 30 seconds).
- Add lemon juice + zest. Stir to combine.
Step 4: Cook the asparagus
- Add asparagus spears directly into the lemon butter sauce.
- Cook for 4–5 minutes until tender-crisp. Don’t overcook—you want that snap.
Step 5: Bring it all together
- Return salmon to the skillet.
- Spoon sauce over the fillets.
- Finish with fresh parsley or a sprinkle of chili flakes if you’re into a little heat.
And that’s it. Dinner’s ready before you’ve even finished scrolling Instagram. 😉
Tips & Variations
Want to tweak this recipe to match your vibe? Here’s how:
- Swap the asparagus: Try broccoli, green beans, or even zucchini. Basically, any veggie that likes to soak up butter.
- Sheet pan version: Not in the mood for stovetop? Toss everything on a sheet pan and bake at 400°F for 15 minutes.
- Herb it up: Fresh dill, thyme, or rosemary take this to another level.
- Dairy-free hack: Use ghee or olive oil instead of butter. Still delicious.
- Extra creamy sauce: Stir in a splash of heavy cream or a spoonful of cream cheese for a thicker, richer sauce.
IMO, the skillet version wins every time because the salmon skin gets extra crispy, but hey, you do you.

Ever tried salmon cold over a salad? Game changer. Especially with a drizzle of leftover lemon butter sauce.
Frequently Asked Questions
Can I use frozen salmon?
Yes, but thaw it completely first. Frozen salmon tends to release extra water, which can mess with your sauce.
Skin on or skin off?
Go with skin on if possible. It crisps up beautifully and keeps the fish moist. If you’re not into eating the skin, just peel it off after cooking.
How long should I cook the asparagus?
4–5 minutes is the sweet spot. Any longer, and you’re entering soggy territory.
What sides go well with this?
Cauliflower rice, zucchini noodles, or even a simple leafy salad. Keep it light and let the salmon shine.
Can I make this in the oven instead?
Totally. Just bake everything on a sheet pan at 400°F for about 15 minutes. Not quite the same crispy skin, but still tasty.
