Baked Salmon in Foil with Asparagus and Lemon Garlic Butter Sauce
Tired of dry, boring salmon? I know the feeling. You spend good money on a nice piece of fish, and it comes out of the oven looking sad and tasting like cardboard.
For years in my restaurant kitchens, we had fancy ways to cook fish perfectly. But at home, you don’t need all that. You just need a secret weapon: aluminum foil.
This recipe keeps the salmon juicy, the asparagus tender, and the cleanup is almost zero. This is the simple, perfect salmon dinner you’ve been looking for.
What You’ll Need
This recipe uses simple stuff you can find anywhere. The magic is in how we put it all together.
- Salmon Fillets: Get about 6 ounces per person. Skin on or off is fine.
- Asparagus: One bunch should do it. Look for stalks that are firm, not limp.
- Butter: Use unsalted so you can control the saltiness.
- Garlic: Fresh minced garlic is best. The stuff in a jar just isn’t the same.
- Lemon: You’ll need one for juice and slices.
- Olive Oil: Just a little bit to coat the asparagus.
- Salt and Black Pepper: For taste.
- Fresh Parsley: Optional, but it makes everything look and taste better.
Tools You’ll Use
You don’t need anything fancy for this.
- A baking sheet
- Aluminum foil
- A small bowl
- A knife and cutting board
Pro Tips
After making this dish thousands of times, I’ve learned a few things. Here are my top tips to make it perfect every time.
- Don’t Overcook the Salmon. This is the number one mistake. Salmon cooks fast. It’s done when it flakes easily with a fork. If you’re not sure, it’s better to undercook it a little. It will keep cooking from the heat in the foil pack.
- Match Asparagus Size. If you have super thick asparagus stalks, they will need more time to cook. If they’re pencil-thin, they’ll cook fast. Try to get medium-sized stalks. If they are thick, just add them to the foil pack a few minutes before the salmon.
- Pat the Salmon Dry. Before you put any salt or pepper on your salmon, pat it completely dry with a paper towel. This helps it season better and get a nicer texture.
- Save Some Sauce for Later. Make a little extra lemon garlic butter. Drizzle it over the cooked salmon right before you serve it. It makes a huge difference.
Substitutions and Variations
Don’t have something on the list? No problem. Cooking is all about making it your own.
| Ingredient | Substitution Idea | Note |
|---|---|---|
| Asparagus | Green beans, zucchini | Adjust cook time |
| Salmon | Trout, cod, halibut | Thinner fish cooks faster |
| Butter | Ghee, olive oil | For dairy-free |
| Parsley | Dill, chives | Gives a different flavor |
You can also add other things to the foil packs.
- Thinly sliced onions or shallots.
- A handful of cherry tomatoes.
- A sprinkle of red pepper flakes for some heat.
Make-Ahead Tips
You can prep the foil packets in the morning or even the night before.
Just assemble everything in the foil, seal them up, and keep them in the fridge. When you’re ready to eat, just pop them in the oven. You might need to add a couple of minutes to the cooking time.
How to Make Baked Salmon in Foil
Step 1: Get your oven ready. Set it to 400°F (200°C). Lay out a big piece of foil on your baking sheet for each salmon fillet.
Step 2: Prep the asparagus. Snap off the tough, woody ends. Put the asparagus on the foil, drizzle with a little olive oil, and sprinkle with salt and pepper.
Step 3: Get the salmon ready. Pat your salmon fillets dry with a paper towel. Place one fillet on top of the asparagus on each piece of foil. Season the fish with salt and pepper.
Step 4: Make the sauce. In a small bowl, mix together the melted butter, minced garlic, and lemon juice.
Step 5: Assemble the packs. Pour the lemon garlic butter sauce over each salmon fillet and the asparagus. Top with a few slices of lemon.
Step 6: Fold up the foil packets. Bring the long sides of the foil together and fold them a few times to seal. Then fold in the short sides. You want a sealed packet so the steam can’t get out.
Step 7: Bake for 12-15 minutes. The exact time will depend on how thick your salmon is.
Step 8: Check for doneness. Carefully open one packet (the steam will be hot!). The salmon should flake easily with a fork. If not, seal it back up and cook for a few more minutes.
Step 9: Garnish and serve. Sprinkle with fresh parsley and serve it right in the foil packet.

Cooking Time Efficiency Tips
| Cook Time | Temperature | Tip |
|---|---|---|
| 12-15 min | 400°F / 200°C | For 1-inch thick salmon |
| 10-12 min | 400°F / 200°C | For thinner salmon |
| + 2-3 min | Broil High | For a little color |
To make this on a busy night, use pre-minced garlic and pre-washed asparagus. The whole thing can be ready in under 25 minutes.
Leftovers and Storage
If you have leftovers, they store really well.
Let the salmon cool down completely. You can store it in the foil packet or move it to an airtight container. It will keep in the fridge for up to 3 days.
To reheat, put it in the oven at a low temperature (like 275°F) until it’s just warmed through. This keeps it from drying out. Avoid the microwave if you can.
Frequently Asked Questions
Q1. How do I know when the salmon is cooked?
Ans: The easiest way is to poke it with a fork. If it flakes apart easily, it’s done. The inside should be light pink and not translucent.
Q2. Can I use frozen salmon?
Ans: Yes. Let it thaw completely in the fridge overnight. Before you cook it, make sure to pat it very, very dry with paper towels. Frozen fish holds a lot of water.
Q3. Why did my asparagus turn out mushy?
Ans: This usually happens if the asparagus was too thin or if it was overcooked. Next time, try using thicker stalks or reducing the cook time by a couple of minutes.
Q4. Can I cook this on the grill?
Ans: Absolutely. Place the foil packets on a preheated grill over medium heat. Cook for about 10-14 minutes, depending on your grill. It’s a great way to cook in the summer.
