Timing

Cooking Time: 15-18 minutes
Total Time: 25-28 minutes
This recipe requires approximately 40% less active cooking time than traditional stovetop methods, making it perfect for multitasking in the kitchen. The foil packet method allows you to prepare multiple servings simultaneously, reducing overall meal prep time by up to 30 minutes when cooking for a family.
Step 1: Prepare Your Foil Packets
Preheat your oven to 400°F (200°C). Cut four large pieces of heavy-duty aluminum foil, each measuring approximately 12×18 inches. The key here is ensuring your foil pieces are large enough to create a proper seal. Lightly brush each foil sheet with olive oil to prevent sticking. This simple step prevents your beautiful salmon from tearing when you unwrap your perfectly cooked packets.
Step 2: Create the Garlic Butter Mixture
In a small bowl, combine the melted butter, minced garlic, lemon juice, oregano, and paprika. Whisk this mixture until it’s completely emulsified – this should take about 30 seconds of vigorous whisking. The aroma alone will tell you this Garlic Butter Salmon In Foil is going to be extraordinary. This butter mixture can be prepared up to 24 hours in advance and stored in the refrigerator.
Step 3: Season and Assemble
Place each salmon fillet in the center of a prepared foil sheet. Season both sides generously with salt and pepper. If you’re including vegetables, arrange them around the salmon, creating a colorful and nutritious bed. Drizzle each fillet with the garlic butter mixture, ensuring every surface is coated. Don’t be shy with the butter – it’s what creates that incredible flavor and keeps your salmon incredibly moist.
Step 4: Seal the Packets
Bring the long sides of the foil together over the salmon and fold down in 1/2-inch increments to create a tight seal. Fold up the shorter ends, ensuring no steam can escape. Your packets should look like sealed pouches with no gaps. Proper sealing is crucial for the steam-cooking process that makes this Garlic Butter Salmon In Foil so tender and flavorful.
Step 5: Bake to Perfection
Place the sealed packets on a large baking sheet and bake for 15-18 minutes, depending on thickness. A good rule of thumb is 4-5 minutes per 1/2 inch of thickness. The internal temperature should reach 145°F (63°C) for perfectly cooked salmon. Let the packets rest for 2-3 minutes before carefully opening to avoid steam burns.

Common Mistakes to Avoid
Overcooking: The most frequent error is leaving salmon in too long. Remember, fish continues cooking even after removal from heat. Start checking at 12 minutes for thinner fillets.
Inadequate Sealing: Loose foil packets allow steam to escape, resulting in dry fish. Take time to create proper seals – your patience will be rewarded with incredibly moist salmon.
Skipping the Rest Period: Opening packets immediately after cooking releases all the flavorful steam. Let them rest 2-3 minutes for optimal results.
Using Thin Foil: Regular foil can tear easily. Invest in heavy-duty foil or double-layer regular foil for best results.
Storing Tips for the Recipe
Refrigerator Storage: Leftover Garlic Butter Salmon In Foil keeps for up to 3 days in the refrigerator. Store in airtight containers with any remaining packet juices to maintain moisture.
Freezer Storage: While fresh is best, cooked salmon can be frozen for up to 2 months. Wrap tightly in freezer-safe containers.
Reheating: Gently reheat in a 300°F oven for 8-10 minutes, or flake cold salmon over salads for a completely different meal experience.
Meal Prep: Assemble packets up to 4 hours ahead and refrigerate until ready to bake. This makes weeknight dinners incredibly simple.
