This stuffed salmon transforms an already excellent protein into something truly extraordinary with minimal effort. The combination of tender fish with a Mediterranean inspired filling creates an impressive main course that looks far more complicated than it actually is. Vibrant wilted spinach, tangy feta cheese, and sweet roasted red peppers melt together inside the salmon as it bakes, infusing each bite with incredible flavor while keeping the fish perfectly moist. The presentation alone makes this dish worthy of special occasions, yet its straightforward preparation fits comfortably into weeknight cooking routines when you need something that feels a bit more special than your usual dinner rotation.
I discovered this recipe when trying to recreate a pre made stuffed salmon I had purchased from Whole Foods during a particularly busy week. The store version was quite good, but after making it myself at home, I was amazed at how simple yet superior the homemade version turned out. My family was genuinely impressed at both the presentation and flavor, assuming I had spent hours in the kitchen. The way the feta becomes slightly melty without completely losing its shape creates these wonderful pockets of creaminess throughout the fish that elevate the entire eating experience. Even my youngest, who typically approaches seafood with suspicion, cleared her plate and asked when we could have it again.
Quality Components
- Fresh Salmon Fillets: Choose center cut portions approximately 6 ounces each with uniform thickness. Wild caught offers more pronounced flavor, while farm raised provides consistent mild taste and often thicker cuts that work beautifully for stuffing.
- Baby Spinach: These tender young leaves wilt quickly and have milder flavor than mature spinach. Pre washed varieties save preparation time without sacrificing quality in this cooked application.
- Quality Feta: Select traditional sheep or sheep and goat milk feta packed in brine rather than pre crumbled versions, which often contain anti caking agents that affect texture and flavor.
- Roasted Red Peppers: Jarred versions work perfectly here, offering sweet, slightly smoky notes that complement both the spinach and feta. Drain well and pat dry before chopping to prevent excess moisture in the filling.
- Italian Seasoning: This herb blend typically includes basil, oregano, rosemary, thyme, and marjoram, creating Mediterranean flavor complexity with a single ingredient.
- Paprika: Adds gentle warmth and subtle color to the filling. Smoked paprika can be substituted for deeper flavor if preferred.
- Quality Olive Oil: Choose extra virgin for both cooking the filling and brushing the salmon.
Preparation Method
- Fish Preparation:
- Begin by preheating your oven to 400°F, ensuring it reaches full temperature before the fish goes in. Line a baking sheet with parchment paper for easy cleanup. Pat salmon fillets completely dry with paper towels to remove excess moisture. Using a sharp knife, carefully slice each salmon fillet lengthwise down the center, creating a pocket while leaving the ends intact.
- Seasoning Application:
- Brush the outside and inside of each salmon fillet with olive oil. Season generously with salt and freshly ground black pepper, including the interior pocket.
- Filling Creation:
- Heat a tablespoon of olive oil in a skillet over medium heat. Add the fresh spinach, Italian seasoning, paprika, and a pinch of cayenne. Sauté until the spinach wilts completely but still maintains its bright green color, approximately 2 minutes.
- Filling Integration:
- Allow the spinach mixture to cool slightly for about 3 minutes. Add finely chopped roasted red peppers, crumbled feta cheese, and grated Parmesan. Stir gently to combine.
- Stuffing Technique:
- Using a spoon, carefully fill each salmon pocket with the spinach and feta mixture, dividing it evenly between the fillets.
- Perfect Baking:
- Place the baking sheet with your stuffed salmon in the preheated oven and bake for 12 to 17 minutes, depending on thickness. The ideal doneness occurs when the salmon reaches an internal temperature of 145°F.

My Italian grandmother taught me that fish deserves gentle treatment and complementary flavors rather than heavy sauces that mask its natural goodness. The first time I made this stuffed salmon, I was transported back to her coastal kitchen where simple, quality ingredients transformed into elegant meals without fuss or complexity.
Complete Meal
This elegant stuffed salmon pairs beautifully with couscous, orzo pasta, or a simple Greek salad featuring cucumbers, tomatoes, Kalamata olives, and red onion. Roasted asparagus or green beans with lemon and garlic offer another simple yet elegant accompaniment.
Creative Variations
Transform this recipe by using dairy free alternatives, adding chopped Kalamata olives, or including sun dried tomatoes. Seasonal adaptations include fresh dill in spring or rosemary and thyme in winter.
Storage Wisdom
Store leftovers in airtight containers and consume within three days. Reheat in a 350°F oven for about 8 minutes. Prepare the filling up to two days in advance for efficient meal prep.

After preparing this dish countless times, I've come to appreciate how it exemplifies the beauty of straightforward cooking that produces elegant results. This stuffed salmon has earned its place in my permanent recipe collection.
Frequently Asked Questions
- → Can I use frozen spinach instead of fresh?
- Yes, you can substitute frozen spinach in this recipe. Thaw the frozen spinach completely and squeeze out all excess moisture using a clean kitchen towel or paper towels before sautéing. Use about 1/2 cup of thawed and squeezed frozen spinach to replace the 3 cups of fresh baby spinach.
- → How do I know when the salmon is fully cooked?
- The salmon is fully cooked when it changes from translucent pink to an opaque whitish-pink color. You can check by cutting into the thickest part of the fish - it should flake easily with a fork but still be moist. For medium-cooked salmon, aim for an internal temperature of 125-130°F (52-54°C), and for well-done, 140°F (60°C).
- → Can I prepare this dish ahead of time?
- Yes, you can prepare the filling and stuff the salmon up to 24 hours in advance. Keep the stuffed salmon covered in the refrigerator until ready to bake. You may need to add a few extra minutes to the baking time if cooking straight from the refrigerator.
- → What can I substitute for feta cheese?
- If you don't have feta, goat cheese makes an excellent substitute with its similar tangy flavor and crumbly texture. Other options include ricotta mixed with a bit of salt for a milder flavor, or cream cheese for a richer, creamier filling.
- → Is this recipe keto-friendly?
- Yes, this Stuffed Salmon with Spinach & Feta is keto-friendly with only 4g of carbohydrates per serving. It's high in healthy fats and protein, making it suitable for those following a ketogenic diet.
- → Can I grill this stuffed salmon instead of baking it?
- Grilling stuffed salmon can be tricky as the filling might fall out. However, you can use a fish grilling basket or aluminum foil packets to grill it. Preheat the grill to medium heat (about 375°F) and cook for about 12-15 minutes with the lid closed, or until the salmon is cooked through.
