Ingredients List

For this quick and delicious salmon and spinach recipe, gather these fresh components:

• 4 salmon fillets (about 6 oz each), skin-on preferred for extra flavor
• 8 cups fresh spinach leaves (about 8 oz), rinsed and patted dry
• 3 tablespoons extra virgin olive oil, divided

• 1 lemon (zest and juice)
• 1 teaspoon sea salt
• ½ teaspoon freshly ground black pepper
• ¼ teaspoon red pepper flakes (optional for gentle heat)
• 2 tablespoons fresh dill, chopped (or 2 teaspoons dried)

Possible Substitutions:

• Salmon: Arctic char or ocean trout offer similar texture and flavor profiles
• Spinach: Swiss chard or kale (may require 1-2 minutes longer cooking time)
• Fresh dill: Fresh basil, parsley, or 1 teaspoon dried herbs de Provence
• Olive oil: Avocado oil provides a similar healthy fat profile with a higher smoke point
• Fresh garlic: ½ teaspoon garlic powder (though fresh delivers superior aromatic quality)

Timing

• Preparation: 8 minutes (includes seasoning salmon and preparing spinach)
• Cooking: 12 minutes (pan-searing salmon and wilting spinach)
• Total Time: 20 minutes (35% faster than the average weeknight protein-vegetable combination)

This salmon and spinach recipe can be on your table in less time than ordering takeout and waiting for delivery—not to mention it’s significantly healthier and more cost-effective.

Step-by-Step Instructions

Step 1: Prepare the Salmon

Pat the salmon fillets dry with paper towels to ensure proper searing. Season each fillet generously with salt, pepper, and half the lemon zest. The moisture removal is crucial—it’s the difference between a beautifully seared crust and a steamed, pale fillet. For even flavor distribution, press the seasonings gently into the flesh rather than just sprinkling them on top.

Step 2: Heat Your Pan

Heat a large skillet over medium-high heat and add 2 tablespoons of olive oil. When the oil shimmers and moves freely in the pan (but before it smokes), it’s at the perfect temperature. This usually takes about 1-2 minutes, depending on your stove. Using a properly heated pan prevents the salmon from sticking and creates that restaurant-quality sear that seals in moisture.

Step 3: Cook the Salmon

Place the salmon fillets skin-side down in the hot skillet and cook undisturbed for 4-5 minutes. This allows the skin to crisp up beautifully while the flesh begins to cook from the bottom up. You’ll notice the color of the salmon changing from translucent to opaque from the bottom, gradually moving upward as it cooks.

Step 4: Flip and Finish the Salmon

Carefully flip the salmon and cook for another 2-3 minutes until the internal temperature reaches 125°F for medium-rare or 130°F for medium. If you don’t have a thermometer, look for flesh that flakes easily with a fork but still maintains a slight translucency in the center. Remove the salmon from the pan and set aside on a warm plate.

Step 5: Prepare the Spinach

In the same pan with the flavorful salmon drippings, add the remaining tablespoon of olive oil and the sliced garlic. Sauté for 30 seconds until fragrant but not browned. Garlic becomes bitter when overcooked, so watch it closely—this brief cooking releases its aromatic compounds without developing harsh flavors.

Step 6: Wilt the Spinach

Add the fresh spinach to the pan in batches if necessary, turning gently with tongs as it wilts down. This process happens quickly—usually within 1-2 minutes. The volume reduces dramatically as the spinach releases its moisture. Season with a pinch of salt, black pepper, and red pepper flakes if using.

Step 7: Finish and Serve

Add the lemon juice directly to the spinach and toss to combine. The acid brightens the entire dish and balances the richness of the salmon. Plate the wilted spinach as a bed for the salmon fillets, then sprinkle with fresh dill and the remaining lemon zest. The contrast between the vibrant green spinach and the pink salmon creates an appetizing presentation that’s as beautiful as it is nutritious.

Storing Tips for the Recipe

Maximize the freshness of your salmon and spinach recipe with these storage guidelines:

Short-Term Storage (1-2 days):

• Refrigerate cooked salmon and spinach separately in airtight containers
• Store at the back of the refrigerator where temperatures are most consistent (aim for 37-39°F)
• For best texture, consume within 2 days—salmon quality declines noticeably after 48 hours

Freezing Options:

• While fresh is best, you can freeze cooked salmon for up to 1 month
• Wrap individual portions tightly in plastic wrap, then in foil, before placing in a freezer bag
• Note that the texture will change slightly upon thawing—best used in salmon cakes or salads
• Cooked spinach does not freeze well due to texture changes; prepare fresh for best results

Reheating Guidelines:

• Reheat salmon gently at 275°F in the oven for 10-15 minutes to prevent drying out
• Alternatively, let salmon come to room temperature and serve slightly chilled to preserve texture
• Refresh spinach by quickly sautéing with a drop of olive oil in a hot pan for 30-60 seconds

Meal Prep Strategy:

• Prepare salmon fillets and store uncooked in marinade for up to 24 hours
• Clean and dry spinach, storing with a paper towel in a sealed container for up to 3 days
• Pre-measure and mix dry seasonings in small containers or ziplock bags for grab-and-go cooking

FAQs

Can I use frozen salmon for this recipe?

Yes, but thaw it completely in the refrigerator overnight before cooking. Pat thoroughly dry before cooking, as frozen salmon often releases more moisture. You may need to extend cooking time by 1-2 minutes, but use the visual cues (opaque flesh that flakes easily) rather than strict timing.

How do I know when salmon is perfectly cooked?

Perfectly cooked salmon should be opaque on the outside while maintaining a slightly translucent center. It should flake easily with a fork but still appear moist. For precise results, use an instant-read thermometer—130°F is ideal for medium doneness that’s both safe and succulent.

Can I make this recipe with canned spinach?

Fresh spinach is strongly recommended for this quick-cooking method. Canned spinach is pre-cooked and will become mushy. If fresh isn’t available, frozen spinach (thawed and thoroughly squeezed dry) can work, though the texture and flavor won’t be as vibrant.

Is this recipe suitable for meal prep?

Yes! Cook the salmon slightly less than you normally would (about 1 minute less) if you plan to reheat it later. Store the salmon and spinach separately in airtight containers for up to two days. Reheat gently or enjoy the salmon cold over fresh greens for a different spin.

What can I substitute for olive oil?

Avocado oil works well due to its mild flavor and higher smoke point. Ghee (clarified butter) adds wonderful richness if you’re not concerned about dairy. Coconut oil will impart a slightly different flavor profile but works nicely with the addition of a squeeze of lime instead of lemon.

How can I make this dish spicier?

Add ¼-½ teaspoon of crushed red pepper flakes when sautéing the garlic, or incorporate 1 finely diced jalapeño (seeds removed for moderate heat, included for more intensity). A drizzle of chili oil to finish or a sprinkle of Aleppo pepper adds heat without overwhelming the delicate salmon flavor.

Can I use this recipe for a dinner party?

Absolutely! For entertaining, you can prepare components ahead: season the salmon and clean the spinach earlier in the day, then cook just before serving. For an elegant presentation, consider using individual skillets to serve each portion, or arrange all fillets on a large platter over the spinach bed with lemon wedges and fresh herbs as garnish.
