Ingredients Overview

This foil packet salmon starts with fresh salmon fillets, a great source of lean protein and omega-3 fatty acids. According to the Harvard T.H. Chan School of Public Health, salmon is one of the richest sources of omega-3s, which support heart and brain health. Asparagus and cherry tomatoes round out each packet with fiber and bright, fresh flavor.

Garlic, lemon, and fresh dill season everything simply, letting the salmon shine. Swap in green beans or zucchini if asparagus isn’t in season. The whole dish gets its bright, fresh flavor from just a handful of pantry staples.

Step-by-Step Instructions

Follow these simple steps to build your foil packet salmon meal prep:

Preheat the oven to 400°F and cut four large pieces of foil.
Divide the asparagus and cherry tomatoes evenly among the foil pieces.
Place a salmon fillet on top of the vegetables in each packet.
Drizzle with olive oil, minced garlic, dill, salt, and pepper, then top each fillet with a few lemon slices.
Fold and seal each foil packet tightly, then bake for 15-18 minutes, until the salmon flakes easily with a fork.
Carefully open the packets (steam will escape) and divide into meal prep containers.

Pro Tip: Seal the foil packets tightly so the steam stays trapped inside — this keeps the foil packet salmon moist and helps the vegetables cook evenly alongside the fish.

Meal Prep & Storage Tips

This foil packet salmon is best stored in airtight containers in the refrigerator for up to 3 days, since fish has a shorter shelf life than chicken or beef. Reheat gently in the microwave for 1 minute, or warm in a covered skillet over low heat to avoid drying it out. Freezing is not recommended, as the texture of the salmon and vegetables can suffer once thawed. For best results, plan to eat these meal preps within a few days of cooking.

Variations & Substitutions

Swap asparagus for green beans, broccoli, or zucchini depending on what’s in season. Try a splash of soy sauce and sesame oil in place of the lemon and dill for an Asian-inspired twist. Shrimp or white fish like cod also work well in this foil packet method. Just adjust the cooking time slightly, since thinner cuts of fish cook faster than a full salmon fillet.
