How to Store

• Refrigerate: Store in airtight containers up to 3–4 days.
• Reheat: Microwave in 30-second bursts just until warm, or use a low oven (300°F) for 8–10 minutes. Avoid overcooking.
• Freezer: Salmon freezes well up to 2 months; asparagus can soften.

  If freezing, consider keeping a fresh veggie side to add later.

Health Benefits

• Omega-3s: Salmon brings heart-healthy fats that support brain function and reduce inflammation.
• High-quality protein: Helps with muscle repair and steady energy.
• Fiber and micronutrients: Asparagus offers folate, vitamin K, and prebiotic fiber for gut health.
• Balanced plate: Add whole grains for extra fiber and long-lasting fullness.

Pitfalls to Watch Out For

• Overcooking salmon: It dries out fast. Pull it when the center turns just opaque and flakes easily.
• Crowded pan: If the pan is packed, veggies steam instead of roast. Use a second pan if needed.
• Uneven asparagus size: Very thin spears cook quicker.

  If using thin asparagus, start salmon first, then add asparagus halfway.

• Not salting enough: Season both the fish and veggies for bright, balanced flavor.

Variations You Can Try

• Herb swap: Use dill and lemon for a classic combo, or try basil and parsley for a fresher profile.
• Spice it up: Add smoked paprika or a Cajun blend to the butter mix.
• Sauce twist: Drizzle with Greek yogurt dill sauce or a light tzatziki. For a similar bowl idea, check out this Greek Yogurt Dill Salmon Bowl.
• Carb options: Serve with quinoa, brown rice, or couscous. For a spring-forward side idea, try the flavors in this Lemon Asparagus Easter Salad.
• Meal prep rotation: If you like fish-forward preps, you might also enjoy this quick Teriyaki Salmon Protein Bowl for a change of pace.

FAQ

Can I use frozen salmon?

Yes.

Thaw completely in the fridge overnight, then pat dry before seasoning. Frozen fillets can release extra moisture, so drying them helps you get better browning.

What if I don’t have asparagus?

Broccoli, green beans, or broccolini work well. Adjust roasting time as needed—broccoli may need an extra 3–5 minutes.

Skin-on or skinless salmon?

Either works.

Skin-on helps keep the fish moist; you can lift the flesh off the skin after roasting if you prefer not to eat it.

How do I know when the salmon is done?

Look for opaque flesh that flakes easily with a fork. An instant-read thermometer should read about 125–130°F for medium after a short rest.

Can I make it dairy-free?

Yes. Replace butter with olive oil or a dairy-free butter alternative.

Flavor stays bright thanks to lemon, garlic, and herbs.
