Step‑by‑Step Instructions for Spinach Stuffed Flounder
Step 1: Prepare the Filling
In a mixing bowl, combine the cream cheese, mozzarella cheese, feta cheese, and chopped spinach. Use a spatula to mix until the ingredients are well integrated into a creamy filling, ensuring there are no lumps. The mixture should be thick but spreadable. This makes for an exquisite stuffing that will enhance your Spinach Stuffed Flounder.
Step 2: Season the Fish
Lay your boneless, skinless flounder fillets flat on a clean cutting board. Generously sprinkle Old Bay seasoning over each fillet, ensuring even coverage for a flavorful impact. Allow the seasoned fish to sit for a moment to absorb the flavors while you prepare to stuff and roll each piece. This step sets the foundation for your delicious meal.
Step 3: Stuff and Roll the Fillets
Take one portion of the creamy filling and place it at the tail end of each flounder fillet. Carefully roll the fillet around the filling, ensuring the stuffing stays inside. Place the rolled fillet seam-side down in a lightly greased baking dish. Repeat this process until all fillets are stuffed and rolled, creating a beautiful presentation for your Spinach Stuffed Flounder.
Step 4: Season and Prepare for Baking
Once all the flounder fillets are rolled and arranged in the baking dish, drizzle a little olive oil over the top of each roll. Finish by sprinkling more Old Bay seasoning for added flavor. Preheat your oven to 350°F (175°C) and get ready to bake these delightful parcels of seafood goodness.
Step 5: Bake the Flounder
Place the baking dish in the preheated oven and bake for 20 minutes. Keep an eye on the fish; it should be golden-brown and flake easily when tested with a fork. This step is crucial to achieve that tender, juicy texture synonymous with the perfect Spinach Stuffed Flounder, inviting all to the table.
Step 6: Garnish and Serve
After baking, remove the flounder from the oven and let it cool slightly. Plate each stuffed fillet beautifully, garnishing with freshly chopped parsley or green onions for a pop of color and freshness. This final touch elevates your dish visually and enhances the flavor, making your Spinach Stuffed Flounder irresistible!

Tips for the Best Spinach Stuffed Flounder
Choose the Right Fish: Always opt for medium-thick flounder fillets to prevent tearing during the rolling process; this ensures a beautiful presentation.
Mind the Bones: Before stuffing, take a moment to check for pin bones in the fish. A quick run-through will save you from unexpected bites.
Don’t Overstuff: Ensure some filling remains inside during baking for the best results; overstuffing can cause the delicate fish to burst open.
Preheat Your Oven: Getting your oven to 350°F (175°C) before placing the fish inside is crucial for consistent cooking, ensuring perfectly flaky fillets.
Garnish Thoughtfully: A sprinkle of fresh parsley or green onions not only enhances the presentation of your Spinach Stuffed Flounder but also adds a refreshing flavor note.
Experiment with Fillings: Feel free to customize your stuffing ingredients—herbs, additional seafood, or different cheeses can elevate this dish to a new level of deliciousness!
