Instant Pot Salmon Recipe: Flaky Perfection in 15 Minutes

I developed this Instant Pot method after years of struggling with inconsistent stovetop results. The pressure cooker locks in moisture, delivering perfectly flaky salmon every single time without any guesswork.

This technique requires just 15 minutes from start to finish, including the time it takes for the pot to come to pressure. The steam infuses the fish with gentle heat, preserving its natural tenderness while allowing flavors to develop fully.

What you get is salmon that’s moist, tender, and never overcooked—with a texture that rivals any restaurant preparation. The flaky layers separate effortlessly, revealing the ideal doneness that’s so often elusive with other cooking methods.

The best part? Minimal cleanup and maximum flavor in a fraction of the time. This method works for both fresh and frozen fillets.

Ingredients for Instant Pot Salmon

Minimal ingredients yield restaurant-quality salmon with effortless flaky texture every time.

The salmon quality is paramount. Wild-caught sockeye or coho offer the best flavor and texture for pressure cooking. Whole Foods or Costco typically carry excellent fresh or frozen options. For frozen fillets, thaw slightly (10-15 minutes at room temp) before cooking to ensure even doneness. Look for fillets of uniform thickness—about 1-inch thick works ideal for this method.

No Dijon mustard? Whole grain mustard adds pleasant texture but may alter the sauce consistency. Fresh dill can replace dried at three times the amount. For a citrus variation, substitute lime juice or orange zest. The olive oil can be swapped for avocado oil (higher smoke point), though the flavor profile will be milder. Avoid pre-minced garlic—it lacks the freshness this dish deserves.

Cooked salmon keeps refrigerated for 2-3 days in an airtight container. Reheat gently to preserve moisture. The cooked fillets can be frozen for up to 1 month, though texture may soften slightly. Always bring chilled fish to room temperature before freezing to prevent freezer burn.

Step-by-Step Instructions for Instant Pot Salmon

This method guarantees perfectly cooked, flaky salmon with minimal effort and maximum flavor.

Step 1: Prepare the Salmon Fillets

Pat the 1.5 lb salmon fillets completely dry with paper towels to ensure even seasoning and proper browning. This step removes excess moisture that can dilute flavors and prevent the fish from cooking uniformly.

Season both sides generously with the 0.5 tsp kosher salt and 0.25 tsp freshly ground black pepper. The salt should adhere well to the dry surface. Gently rub the seasoning into the fillets to create a flavorful crust.

Step 2: Create the Aromatic Sauce Base

In a small bowl, whisk together the 2 tbsp lemon juice, 1 tbsp Dijon mustard, minced 3 cloves garlic cloves, 1 tsp dried dill, and 0.5 tsp dried thyme. The mixture should be smooth and well combined, with no visible clumps of mustard.

Drizzle the 1 tbsp extra-virgin olive oil into the sauce and whisk again until emulsified. This creates a cohesive mixture that will coat the salmon evenly and infuse it with bright, herby flavors during cooking.

Step 3: Pressure Cook the Salmon

Pour the 1 cup water or fish stock into the Instant Pot insert. Place the trivet inside, then arrange the seasoned salmon fillets on top. If using frozen fillets, ensure they are separated and not stuck together.

Drizzle the prepared sauce evenly over the salmon fillets. Secure the lid, set the valve to sealing, and pressure cook on high for 3 minutes. For frozen fillets, increase the time to 5 minutes. The salmon is done when it flakes easily with a fork and reaches an internal temperature of 145°F.

Step 4: Release Pressure and Finish

Once the cooking time is complete, allow the pressure to release naturally for 5 minutes, then quick-release any remaining pressure. This gradual release prevents the salmon from overcooking due to sudden temperature changes.

Carefully open the lid and transfer the salmon to a serving platter. The fillets should be opaque and flake easily when tested with a fork. If any parts appear underdone, they will finish cooking during the resting period.

Step 5: Garnish and Serve

Arrange the 4 slices lemon slices around the salmon for a bright, fresh presentation. Sprinkle the 2 tbsp fresh parsley evenly over the top, pressing lightly so it adheres to the sauce.

Let the salmon rest for 2-3 minutes before serving. This allows the juices to redistribute, ensuring each bite is moist and flavorful. Serve immediately with the sauce spooned over the top for the best texture and taste.

Essential Equipment for Great instant pot salmon

Pressure Cooker Essentials

Your Instant Pot is the star here—I use the 6-quart Duo model, which fits 1.5 lb salmon perfectly. Any pressure cooker with a sauté function works, but the Instant Pot’s consistent heat distribution makes all the difference. 💡

Accessory Must-Haves

A sturdy stainless steel trivet keeps the salmon elevated above the liquid for even cooking. I also recommend a pair of long silicone tongs for safely handling hot fillets without damaging their delicate texture.

Liquid Measurement

Always use at least 1 cup water or fish stock to build pressure. For extra flavor, I love Better Than Bouillon fish base—just 1 tsp dissolved in hot water adds depth without overpowering the salmon.

Precision Tools

A digital instant-read thermometer ensures doneness. I trust ThermoWorks for accuracy—check that the thickest part hits 145°F before serving. This small investment guarantees perfect results every time. ⚡

Optional Upgrades

For easy cleanup, use parchment paper slings to lower and lift the salmon. A steamer basket works too, but I find the trivet method more reliable for even cooking. These extras aren’t essential but make the process smoother.
