Dinner doesn't get easier or healthier than this! Lemon Cod and Asparagus are roasted together in a foil packet. Super flavorful dinner with easy cleanup!
Place large foil sheet on baking tray. Spray with cooking oil.
Place slices of one lemon, and half of the onion slices on the foil sheet.
Top lemon and onion slices with asparagus, then another layer of lemon and onion.
Top with cod. Pour butter over the top of the cod, then sprinkle with garlic salt and lemon pepper. Sprinkle bread crumbs (optional) over cod. Top with another layer of aluminum foil.
Roast for 13-15 minutes, until cod starts to flake and asparagus is crisp-tender.
Remove aluminum foil from top and broil on top rack for 1 minute to brown the bread crumbs.
