Servings: 4
Prep Time: 15 minutes
Cook Time: 15–20 minutes
Total Time: About 30–35 minutes

Ingredients

For the Salmon & Vegetables

4 salmon fillets, about 5–6 ounces each
1 bunch asparagus, trimmed
2 tablespoons olive oil
Salt, to taste
½ teaspoon black pepper
½ teaspoon paprika
½ teaspoon Italian seasoning or dried oregano
1 lemon, thinly sliced
2 tablespoons chopped fresh parsley, for garnish

For the Lemon Garlic Sauce

3 tablespoons unsalted butter
4 cloves garlic, finely minced
3 tablespoons fresh lemon juice
1 teaspoon lemon zest
1 tablespoon chopped fresh parsley
Salt and black pepper, to taste

Instructions

1. Preheat the Oven

Preheat your oven to 400°F (200°C).

2. Prepare the Foil Packets

Cut 4 large pieces of aluminum foil, large enough to completely wrap each salmon fillet and some asparagus.

Place a small portion of trimmed asparagus in the center of each piece of foil.

3. Season the Salmon

Place one salmon fillet on top of or beside the asparagus.

Drizzle with olive oil, then season with salt, black pepper, paprika, and Italian seasoning.

Place a few thin lemon slices over each salmon fillet.

4. Make the Lemon Garlic Sauce

In a small saucepan over low heat, melt the butter.

Add the minced garlic and cook for about 30 seconds, just until fragrant. Do not let the garlic brown.

Remove from the heat and stir in:

Lemon juice
Lemon zest
Chopped parsley
A pinch of salt and pepper

5. Assemble the Packets

Spoon the lemon garlic sauce evenly over the salmon and asparagus.

Fold the foil over the ingredients and seal the edges tightly to create individual packets.

6. Bake

Place the foil packets on a baking sheet.

Bake for 15–20 minutes, depending on the thickness of your salmon.

The salmon is ready when it flakes easily with a fork and reaches an internal temperature of 145°F (63°C) at its thickest part.

7. Serve

Carefully open the foil packets, as hot steam will escape.

Sprinkle with fresh parsley and serve immediately with extra lemon wedges if desired.

Recipe Tips

Don’t overcook the salmon: Thicker fillets may need a few extra minutes, while thinner fillets can cook quickly.
Trim the woody ends of the asparagus before cooking.
Use fresh lemon juice for the brightest flavor.
For extra richness, add a little more lemon garlic butter after baking.
If your asparagus spears are very thick, consider placing them in the oven for a few minutes before adding the salmon packets.

Q&A

Can I use frozen salmon?

Yes. Thaw the salmon completely and pat it dry before seasoning and baking.

Can I make this recipe ahead of time?

You can prepare the salmon, asparagus, and sauce ahead of time and refrigerate them separately. Assemble and bake when ready for the best texture.

How do I store leftovers?

Store cooled leftovers in an airtight container in the refrigerator for up to 2–3 days.

Can I use other vegetables?

Yes! Try zucchini, green beans, broccoli florets, bell peppers, or thinly sliced squash. Keep in mind that harder vegetables may need additional cooking time.

Can I cook all the ingredients in one large foil packet?

Absolutely. Place the asparagus and salmon on a large sheet of foil, add the sauce, and seal tightly. You may need to add a few extra minutes to the cooking time.

What if I don’t have fresh parsley?

You can use fresh dill, basil, or a small amount of dried parsley instead.

Is this recipe low-carb?

Yes. Salmon and asparagus are naturally low in carbohydrates, making this a great option for a low-carb or high-protein meal.

Can I make it without butter?

Yes. Replace the butter with olive oil for a lighter, dairy-free lemon garlic sauce.
