Why This Recipe Works

Salmon and feta are soulmates. The richness of the salmon plays beautifully against the tangy, salty feta, while wilted spinach adds earthiness and nutrition without any fuss.

The butterflied technique keeps everything moist and ensures the filling cooks perfectly alongside the fish. And that lemon zest? It brightens every single bite.

Did you know? Salmon is loaded with omega-3 fatty acids, making it one of the healthiest proteins you can cook at home.

Step-by-Step Instructions

This is straightforward, but take your time with the butterflying step. You want to open that salmon like a book.

Step 1: Butterfly the Salmon

Place your salmon fillet skin-side down on a cutting board. Using a sharp knife, carefully cut through the thickest part of the fish horizontally, but stop just before you reach the other side. You’re creating one large, connected piece that opens flat. Pat dry with paper towels.

Step 2: Prepare the Filling

Heat 1 tablespoon of olive oil in a large skillet over medium heat. Add minced garlic and sauté for about 30 seconds until fragrant. Toss in your spinach and cook, stirring occasionally, until wilted and any excess moisture has cooked off, about 3-4 minutes.

Remove from heat and let cool slightly. Stir in the crumbled feta, cream cheese, and lemon zest. Taste it. Add a pinch of salt and pepper if needed (remember, feta is already salty).

Step 3: Season and Fill

Open your butterflied salmon and season the inside lightly with salt and pepper. Spread the spinach-feta mixture evenly inside the salmon, leaving about half an inch from the edges.

Step 4: Tie It Up

Fold the salmon closed and use kitchen twine to gently tie it at two or three points along the length. This keeps everything secure while it bakes.

Step 5: Sear the Exterior

Heat the remaining 1 tablespoon of olive oil in an oven-safe skillet over medium-high heat. Once hot, carefully place the tied salmon in the pan and sear for 2-3 minutes per side until the skin is golden and the exterior has a light crust.

Step 6: Bake

Transfer the skillet to a preheated 375°F oven. Bake for 25-30 minutes, depending on the thickness of your fillets. The salmon is done when it flakes easily with a fork and reaches an internal temperature of 145°F.

Step 7: Rest and Serve

Remove from the oven and let rest for 5 minutes. Drizzle with fresh lemon juice before serving. Carefully snip and remove the twine at the table for that impressive reveal.

Pro Tips for Perfect Results

A few things I’ve learned that make this recipe shine every single time.

The butterflying step matters. If you’re nervous about doing it yourself, ask your fishmonger to butterfly it for you, no judgment. Fresh spinach wilts down fast, so don’t panic when it looks like a lot at first.

Make sure your oven is fully preheated before the salmon goes in. This ensures even, gentle cooking.

Variations & Substitutions

This filling is flexible. Swap the spinach for arugula or kale if you prefer a peppery bite. Use goat cheese instead of feta for a creamier filling. Add diced sun-dried tomatoes or a handful of fresh dill to the mixture for extra Mediterranean flavor. Cream cheese keeps everything together, but ricotta works if that’s what you have.

“Fish is the gift from the ocean. Treat it with respect and it will reward you.”

This recipe is exactly that philosophy in action.

Serve It Right

This salmon is stunning with roasted asparagus, a simple arugula salad, or crusty bread to soak up the pan juices.

A crisp white wine, like Sauvignon Blanc or Pinot Grigio, pairs beautifully. The Mediterranean flavors shine brightest when you keep the sides simple and fresh.
