- Garlic cloves (2, minced): Offers a fragrant punch that complements both spinach and salmon beautifully.
- Baby spinach (3 cups): Lets the dish stay light and fresh, blending perfectly with the creamy feta.

How to Make Spinach and Feta Stuffed Salmon Recipe
Step 1: Preheat Your Oven
Start by getting your oven nice and hot at 400 degrees Fahrenheit (200 degrees Celsius). A properly heated oven is essential to cook the salmon perfectly, sealing in moisture while baking the filling to creamy perfection.
Step 2: Sauté Onions in Olive Oil
Heat one tablespoon of olive oil in a skillet over medium-high heat. Toss in the diced onion and cook them until they turn translucent, about 3 to 4 minutes. This softens their natural sweetness, laying the flavor foundation for the filling.
Step 3: Add Garlic for Aroma
Next, add the minced garlic to the skillet and cook for just 30 seconds. Be careful not to burn it—this step releases a wonderful garlicky aroma that elevates the entire dish.
Step 4: Wilt Spinach and Combine with Feta
Stir in the baby spinach and cook another 30 seconds until just wilted. Remove the pan from heat and gently fold in the crumbled feta cheese. This mixture is the creamy, savory stuffing that will make your salmon filling unforgettable.
Step 5: Create the Salmon Pockets
Take each salmon fillet and carefully flip it on its side. With a sharp knife, slice lengthwise to make a pocket without cutting all the way through. The aim is to create a small cavity perfect for stuffing.
Step 6: Stuff the Spinach and Feta Mixture
Divide the spinach-feta filling evenly among the four fillets, gently pressing the mixture inside each pocket. This step is where your dish truly comes to life, bursting with flavor inside every bite.
Step 7: Season and Bake
Drizzle the remaining tablespoon of olive oil over the stuffed salmon fillets and sprinkle them with kosher salt. Place them on a parchment-lined, rimmed baking sheet. Bake in your preheated oven for 8 to 10 minutes until the salmon flakes easily with a fork but still feels juicy and tender inside.
How to Serve Spinach and Feta Stuffed Salmon Recipe

Garnishes
Adding a sprinkle of fresh microgreens on top gives your dish a beautiful, fresh finishing touch with a lovely peppery flavor. You could also squeeze a bit of lemon juice right before serving for a citrusy brightness that cuts through the richness.
Side Dishes
This Spinach and Feta Stuffed Salmon Recipe pairs beautifully with light, healthy sides. Consider serving it alongside roasted asparagus or a vibrant quinoa salad to keep the meal balanced and colorful. Creamy mashed potatoes or garlic butter couscous are also fantastic comfort options.
Creative Ways to Present
If you want to impress your guests, try placing the stuffed salmon on a bed of lemon-herb rice or alongside a swirl of bright beet puree. You can also plate it with a drizzle of basil pesto or a dollop of Greek yogurt mixed with cucumber for a refreshing sauce.
Make Ahead and Storage
Storing Leftovers
If you happen to have leftovers, store the salmon stuffed with spinach and feta in an airtight container in the refrigerator. It’s best eaten within two days to enjoy optimal freshness and flavor.
Freezing
This recipe is not ideal for freezing once cooked because the stuffed salmon can become watery and lose texture. However, you can prepare the stuffing and salmon fillets separately ahead of time, then combine and cook fresh when ready.
Reheating
To reheat leftover stuffed salmon, gently warm it in a low oven set to 275 degrees Fahrenheit (135 degrees Celsius) or in a covered skillet over low heat. Avoid microwaving to keep the salmon moist and prevent the feta from drying out.
FAQs
Can I use frozen salmon fillets for this recipe?
Yes, but it’s best to thaw them completely and pat them dry to ensure they cook evenly and the stuffing adheres well before baking.
Is feta cheese essential in the stuffing?
Feta adds a distinct tang and saltiness that complements the spinach and salmon beautifully, but you can substitute it with goat cheese or cream cheese if preferred.
Can I add other herbs or spices to the stuffing?
Absolutely! Fresh dill, parsley, or a pinch of crushed red pepper flakes would add a lovely twist without overpowering the dish.
How do I know when the salmon is fully cooked?
The salmon is done when it flakes easily with a fork and reaches an internal temperature of 145 degrees Fahrenheit (63 degrees Celsius).
Is this dish suitable for a low-carb diet?
Definitely! This recipe is naturally low in carbs thanks to the wholesome ingredients, making it perfect for those following keto or low-carb lifestyles.
