Ingredients Needed to Make Stuffed Salmon With Spinach and Feta

• 4 x 6-ounce salmon fillets (longer pieces work best for stuffing)
• 2 tablespoons olive oil, divided
• 3 cups packed baby spinach
• 1 teaspoon Italian seasoning
• ½ teaspoon paprika (smoked or regular)
• Pinch of cayenne pepper (optional, for a gentle kick)
• Approx. 5.3 ounces feta cheese (about 150g), crumbled or softened
• ¼ cup freshly grated parmesan cheese
• ¼ cup roasted red peppers, chopped into ¼-inch pieces
• Salt and black pepper to taste

Instructions to Make Stuffed Salmon With Spinach and Feta

Preheat the Oven and Prep the Salmon

Start by preheating your oven to 400°F. Line a baking sheet with parchment paper for easier cleanup. Place your salmon fillets on the sheet, skin-side down. Now, here’s where the magic begins: use a sharp knife to cut a slit down the center of each fillet, lengthwise. You’re basically making a pocket—don’t slice all the way through. You want the ends and bottom still intact to hold in that delicious filling.

Season and Oil the Fish

Brush each fillet with 1 tablespoon of olive oil, getting into the cut a bit. Season them with salt and black pepper. Set aside while you work on the filling. (They’ll hang tight for a few minutes.)

Cook the Spinach Mixture

In a large skillet over medium heat, warm the remaining tablespoon of olive oil. Toss in your spinach, Italian seasoning, paprika, cayenne (if using), salt, and pepper. Sauté until the spinach wilts—this takes just 2-3 minutes. Stir gently so you don’t burn the spices.

Mix in Cheese and Peppers

Once the spinach is wilted, turn off the heat. Stir in the roasted red peppers, crumbled feta, and parmesan. Use the back of your spoon or spatula to “mush” the feta a bit, helping the mixture stick together. This is the flavor-packed heart of your stuffed salmon—don’t be afraid to taste and adjust the seasoning!

Stuff the Salmon

Using a spoon, gently fill each slit in the salmon fillets with the spinach and feta mixture. Don’t worry about it being perfect—rustic and overflowing is totally fine here. You want each bite to have a good mix of salmon and filling.

Bake to Perfection

Pop the tray into your preheated oven and bake for 12 to 17 minutes. The timing depends on the thickness of your fillets. Check for doneness by cutting into the thickest part of the salmon—it should be opaque and flake easily with a fork.

Serve Hot

Once out of the oven, serve hot while everything’s warm and melty. That creamy filling with the tender fish? Absolute heaven.

What to Serve with Stuffed Salmon With Spinach and Feta

This dish is a flavor bomb on its own, but pairing it with the right side kicks it up another notch. For a light option, go with roasted broccoli and carrots or a crisp green salad. If you’re craving something cozy, mashed or roasted potatoes (regular or sweet) bring the comfort. You can also lean into the Mediterranean vibes by serving it over orzo, couscous, or lemon basil parmesan pasta. Want to keep things extra wholesome? Quinoa, farro, or brown rice all work beautifully. And if you’re feeding a bigger group, a side of easy breakfast potatoes can make it feel brunchy and fun. Bottom line: this salmon plays well with pretty much anything that’s not too overpowering.

Key Tips for Making Stuffed Salmon With Spinach and Feta

Tip #1: Fresh salmon makes a difference. If you can, opt for fresh fillets instead of frozen—especially if it’s for a dinner party. Tip #2: Ask the folks at the seafood counter to cut longer fillets; they’re way easier to stuff and look great on the plate. Tip #3: Don’t overbake! Keep an eye on your salmon during the last few minutes. It should be just cooked through—still juicy, never dry. Tip #4: If feta isn’t your thing, goat cheese is a good sub. Just keep in mind it’s a bit tangier. Tip #5: Add a squeeze of lemon right before serving. It brightens everything up and balances the richness of the fish and cheese. Tip #6: Want a shortcut? Use frozen spinach, thawed and squeezed dry—it’ll save you a few minutes on a hectic night. Tip #7: If you’re into meal prep, make the filling in advance and refrigerate it—it holds up great for 2-3 days.

Storage and Reheating Tips for Stuffed Salmon With Spinach and Feta

Let’s be real: stuffed salmon is best eaten fresh from the oven. But if you’ve got leftovers, don’t toss them! Store any extras in an airtight container in the fridge for up to 3 days. When it’s time to reheat, skip the microwave (unless you like your salmon dry and rubbery—hard pass). Instead, pop it in a 300°F oven for about 10-12 minutes, or until warmed through. Cover it loosely with foil to keep the moisture in. You can also reheat it in a skillet over low heat with a splash of water and a lid on top—it’ll steam gently back to life. Just don’t overdo it or the salmon will lose its lovely texture. One more thing: this dish doesn’t freeze well because of the dairy in the filling, so enjoy it within a few days.
