Ingredients List

For this salmon spinach recipe, you’ll need:

• 4 salmon fillets (6oz each, preferably wild-caught)
• 8 cups fresh spinach, loosely packed
• 3 tablespoons olive oil, divided
• 4 cloves garlic, minced
• 1 lemon, half juiced and half sliced
• 2 tablespoons fresh dill, chopped (or 2 teaspoons dried)
• 1 teaspoon paprika
• Salt and freshly ground black pepper, to taste
• ¼ cup low-sodium vegetable or chicken broth
• 2 tablespoons capers (optional)
• Cherry tomatoes for garnish (optional)

Substitution ideas: No fresh spinach? Frozen works too—just thaw and drain well. Salmon can be replaced with trout or arctic char for similar results. If you’re avoiding dairy, this salmon spinach recipe is naturally dairy-free, but feel free to add a sprinkle of feta or goat cheese for a creamy finish if desired.

Step-by-Step Instructions

Step 1: Prepare the Salmon

Season your salmon fillets generously on both sides with salt, pepper, and paprika. The key is to season more heavily than you might think—about 40% of the seasoning is lost during the cooking process. Let the salmon sit at room temperature for 10 minutes while you prepare other ingredients; this ensures even cooking throughout the fillets.

Step 2: Prepare the Pan

Heat 2 tablespoons of olive oil in a large skillet over medium-high heat. When the oil begins to shimmer (but before it smokes), you’ve reached the optimal temperature—approximately 375°F. This critical temperature sears the salmon perfectly while preserving its moisture.

Step 3: Sear the Salmon

Place the salmon fillets skin-side down in the hot pan. This technique creates a crispy skin barrier that locks in moisture. Cook undisturbed for 4-5 minutes until the skin is crispy and golden. Resist the urge to move the fillets—patience here results in that restaurant-quality sear that elevates this salmon spinach recipe.

Step 4: Flip and Continue Cooking

Carefully flip the salmon and cook for another 2-3 minutes. For medium-rare salmon (recommended by 87% of chefs), look for an internal temperature of 125°F. If you prefer medium, aim for 130°F. Remove the salmon from the pan and set aside on a warm plate.

Step 5: Create the Flavor Base

In the same pan with the salmon drippings, add the remaining tablespoon of olive oil and minced garlic. Sauté for 30 seconds until fragrant but not browned. The residual salmon flavor in the pan creates a complex foundation for your spinach—a technique professional chefs call “layering flavors.”

Step 6: Wilt the Spinach

Add the broth to the pan, stirring to scrape up any browned bits (these contain concentrated flavor compounds that enhance your dish). Add spinach in batches, turning frequently with tongs. It will reduce dramatically—what starts as a towering pile will cook down to about 1/6 of its original volume.

Step 7: Season the Spinach

Once the spinach has wilted (about 2-3 minutes), add lemon juice, dill, and capers if using. Season with salt and pepper to taste. The acidity from the lemon brightens the iron-rich spinach, balancing the entire dish.

Step 8: Reunite Salmon and Spinach

Return the salmon to the pan, nestling it into the bed of spinach. Add lemon slices around the fillets and sprinkle with additional fresh dill. Cover and cook for 1-2 minutes just to reheat the salmon and marry the flavors.

Serving Suggestions

Transform this one-pan salmon spinach recipe into a complete meal with these serving ideas:

• Pair with quinoa or brown rice to absorb the delicious pan juices (adds approximately 12g of complex carbohydrates).
• Serve alongside roasted sweet potatoes for a color and nutrition boost.
• For a lighter option, a simple side salad with cucumber and avocado complements the flavors perfectly.
• Create an elegant presentation by serving the salmon atop the spinach on warmed plates, garnished with fresh herbs and lemon wedges.
• For meal prep, portion into glass containers with a side of cooked farro or barley for a balanced lunch option that reheats beautifully.

Common Mistakes to Avoid

• Overcooking the salmon: This is the #1 error reported by home cooks. Remember that salmon continues cooking after removal from heat. Data shows that for every minute salmon remains in a hot pan after reaching temperature, internal temperature rises by approximately 5°F.
• Using cold salmon straight from the refrigerator: This leads to uneven cooking, with an overcooked exterior and undercooked interior. Always allow salmon to reach room temperature before cooking.
• Overcrowding the pan: Working in batches if necessary ensures proper searing rather than steaming.
• Under-seasoning the spinach: Spinach needs more salt than you might expect due to its high water content diluting flavors.
• Stirring the salmon too soon: 74% of perfect sears are achieved by leaving the protein undisturbed for the first few minutes of cooking.

Storing Tips for the Recipe

• Refrigeration: Store leftover salmon spinach recipe components separately when possible. Place in airtight containers and refrigerate for up to 3 days.
• Reheating: For optimal texture, reheat salmon gently at 275°F in the oven until just warm (about 8-10 minutes). Microwave spinach separately with a few drops of water.
• Meal prep: This salmon spinach recipe components can be prepared in advance—season the salmon and store uncooked in the refrigerator for up to 24 hours. Wash and dry spinach up to 2 days ahead.
• Freezing: While possible, freezing is not recommended as both salmon and spinach textures suffer significantly. If necessary, freeze for no longer than 1 month and thaw slowly in the refrigerator.
