Ingredient Notes

Salmon. I used Coho salmon fillets, but you could use any type of salmon. Defrost it first if frozen to avoid having too much liquid in the packets. You also want to remove the skin to avoid a strong fishy taste.
Asparagus. Use asparagus that is the same thickness so it cooks evenly. Thin asparagus will cook too fast and turn mushy, so try to use ones that are the width of your pinky finger. Green beans, broccoli, and thinly sliced carrots are a great substitute if you don't have asparagus.
Potatoes. The key is to cut your potatoes quite small so they cook quickly - just a bit larger than the size of a hashbrown. You can use any type of potato or baby potato. For thicker chunks of potato or halved baby potatoes, parboil in salted water for 8 minutes first, then drain and rinse with cold water.
Garlic butter sauce. Made with butter, minced garlic cloves, lemon juice, salt, and black pepper. Feel free to add your favorite seasonings or spices.

How To Make Lemon Garlic Butter Baked Salmon With Asparagus And Potatoes

Step-By-Step Instructions

Preheat your oven to 400 degrees F.
Lay out four large pieces of aluminum foil. Break the woody ends of the asparagus spears and divide evenly on foil.
Place a salmon fillet on top of the asparagus and sprinkle with salt and pepper.
Add a tablespoon of butter on top of each fillet, and divide the minced garlic between the salmon parcels.
Divide potatoes evenly around the salmon.
Squeeze the juice from half a lemon over each fillet and place a lemon slice on top.

Fold the foil over the salmon tightly, using a drugstore fold, and seal the edges tightly. Place salmon foil packets on a baking sheet and bake for 20-25 minutes, until the salmon is cooked and the potatoes are tender.

Expert Tips

Remove the skin from the salmon before placing it in the foil packet.
If your potatoes are large, parboil in a pot of boiling water for 8 minutes, then drain and rinse with cold water.
Seal the foil packets tightly so the ingredients steam properly. If there is any gap, steam will get out, and they will cook slower.
If your oven has hot spots or cooks unevenly, rotate the pan halfway through the cooking time.
Check the asparagus in a foil packet in the oven after 20 minutes. When the internal temperature reaches 145 degrees F, it's ready.

Variations

Top the salmon with compound butter made by combining softened butter, minced garlic, and chopped fresh dill, rosemary, or thyme in a small bowl.
Spice it up by adding a sprinkle of red pepper flakes or Cajun seasoning.
Make a creamy sauce by adding half a tablespoon of cream cheese or coconut milk before sealing the foil.
Use lime juice instead of lemon and add chopped cilantro as a garnish.
