Insta Pot Salmon Recipe: Pressure-Cooked Flaky Perfection

Pressure cooking transforms salmon into perfectly flaky fillets every time, with minimal effort and maximum flavor. This method locks in moisture while infusing the fish with subtle steam-enhanced taste.

The Instant Pot creates an ideal environment for salmon—gentle, even heat that prevents overcooking. With just 5 minutes of cooking time, you achieve results that rival any oven-baked version.

What emerges is tender, buttery salmon that separates easily with a fork. The pressure cooking process ensures even doneness throughout, eliminating the risk of dry edges or undercooked centers.

Serve with your favorite sides for a meal that looks and tastes like it came from a professional kitchen. The technique is as reliable as it is impressive.

Ingredients for Insta Pot Salmon

Fresh salmon plus a few pantry staples. That’s all it takes for this flaky masterpiece.

The salmon quality is key here. Wild-caught from Whole Foods or Costco is my go-to—firm, bright orange flesh, no fishy smell. Fresh is ideal (look for the sell-by date), but frozen works perfectly if thawed overnight in the fridge. Skin-on fillets hold together better during cooking, but skinless is fine too. Just pat them bone-dry before seasoning.

No fresh dill? Dried at one-third the amount works, or swap in fresh parsley. Out of Dijon? Whole-grain mustard adds great texture. Honey can be maple syrup or agave if you’re avoiding bee products. The soy sauce? Coconut aminos for gluten-free. Don’t skip the lemon though—it brightens everything up.

Salmon cooks fast, so have your sides ready. Leftovers? They reheat okay but are best cold the next day. Keeps 2-3 days in the fridge. I wouldn’t freeze cooked salmon—it gets mushy. The sauce components can be prepped ahead (the dill, garlic, lemon) and kept separate until cooking.

Step-by-Step Instructions for Pressure-Cooked Salmon

Here’s the method I swear by for perfectly flaky salmon every single time.

Step 1: Prepare the Salmon and Aromatics

Pat the 1.5 lb salmon fillets completely dry with paper towels—this prevents steaming in the pressure cooker. Season both sides evenly with the 0.5 tsp salt and 0.5 tsp black pepper. I always use a paper towel to grip the fillets; it keeps my hands clean and prevents slipping.

Zest the 1 whole lemon into a small bowl, then juice it—you should get about 3-4 tablespoons of juice. Mince the 3 cloves garlic cloves finely, and chop the 2 tbsp fresh dill. In a separate bowl, whisk together the 1 tbsp dijon mustard, 1 tbsp soy sauce, 1 tbsp honey, half the lemon juice, and half the lemon zest. This creates a bright, tangy glaze that’ll infuse the fish.

Step 2: Sear the Salmon for Flavor Depth

Set your Instant Pot to the “Sauté” function on normal heat. Add the 1 tbsp olive oil and let it heat until it shimmers. Place the salmon fillets skin-side up in the pot and sear undisturbed for 2 minutes—you’re looking for a light golden crust on the bottom.

Real talk: This step isn’t just for color. Searing locks in moisture and creates that fond on the bottom of the pot that’ll flavor the cooking liquid. Gently flip the fillets and sear the other side for just 1 minute. Remove the salmon to a plate and turn off the Sauté function.

Step 3: Pressure Cook with Aromatics

Pour the 1 cup water into the Instant Pot and use a wooden spoon to scrape up all those delicious browned bits. Add the remaining lemon juice, lemon zest, minced garlic, and half the chopped dill to the water. Place the trivet in the pot and arrange the seared salmon fillets on top.

Secure the lid, set the valve to “Sealing,” and cook on high pressure for 3 minutes. I know it seems short, but salmon cooks fast under pressure. The fillets should flake easily with a fork when done. Once the cooking time is complete, let the pressure release naturally for 5 minutes, then quick-release any remaining pressure.

Step 4: Finish with Herbs and Butter

Carefully remove the salmon to a serving platter. Here’s the thing—salmon continues cooking even after you take it out, so work quickly. Stir the 2 tbsp butter into the cooking liquid in the Instant Pot until melted, then pour this buttery, citrusy sauce over the salmon.

Garnish with the remaining chopped dill. The fish should be opaque and flake apart with the gentlest touch of your fork. Serve immediately with the sauce spooned over each portion. This method guarantees moist, tender salmon with a bright, flavorful finish that’ll impress anyone at your table.

Make-Ahead Tips for insta pot salmon

Prep Ahead Sauce

Mix your dijon mustard, soy sauce, honey, and lemon components the night before. Store in an airtight container in the fridge. This deepens the flavors and saves 5 minutes of prep on cooking day.

Salmon Storage

Keep your 1.5 lb salmon fillets unopened in the fridge until ready to cook. If using frozen, transfer to the fridge 24 hours before cooking to thaw slowly. Never thaw at room temperature.

Pre-Cut Aromatics

Chop your 2 tbsp fresh dill and mince the 3 garlic cloves the morning of cooking. Store separately in small containers. This prevents browning and keeps flavors fresh until cooking time. 💡

Trivet Ready

Place your Instant Pot trivet in the pot with the 1 cup water the night before. This small step ensures you won’t forget it when you’re ready to cook. The trivet prevents the salmon from sitting directly in liquid.

Quick Assembly

Have all ingredients measured and prepped before starting. The entire cooking process moves fast—just 3 minutes under pressure—so organization is key. I keep everything in small bowls on the counter.

Next-Day Service

This dish actually tastes better the next day. Cook the salmon, let it cool, then store in the fridge. Serve cold or at room temperature for a delicious 2-3 day meal. 🥗
