Make Spinach Stuffed Flounder: A Simple Method

Follow these easy steps to create your Spinach Stuffed Flounder:
Step 1: Sauté the Vegetables
In a large skillet, heat the olive oil over medium heat. Add the diced onion and sauté until translucent, about 3-4 minutes. Then, stir in the minced garlic and cook for an additional minute until fragrant.
Step 2: Add the Spinach
Add the baby spinach leaves to the skillet, along with a pinch of salt and pepper. Cook until the spinach has wilted, which should take about 2-3 minutes. Stir in the crushed red pepper flakes for a hint of spice.
Step 3: Prepare the Stuffing
In a mixing bowl, combine the sautéed spinach mixture with the cottage cheese, grated Parmesan cheese, and sun-dried tomatoes. Mix well to combine all the ingredients evenly.
Step 4: Stuff the Flounder
Preheat your oven to 375°F (190°C). Lay the flounder fillets on a clean surface, and spoon an even amount of the spinach stuffing onto each fillet. Carefully roll the fillets up, placing them seam-side down in a baking dish.
Step 5: Add Final Touches
In a small bowl, mix the melted butter with lemon juice and Old Bay seasoning. Drizzle this mixture over the stuffed flounder.
Step 6: Bake
Place the baking dish in the preheated oven and bake for 20-25 minutes, or until the fish is opaque and flakes easily with a fork.
