How to Make Cheesy Spinach Casserole
STEP 1. Preheat the oven. Set to 350°F.
STEP 2. Prepare the topping. Combine fried onions, Panko breadcrumbs, and Gouda in a small bowl, then mix well and set aside.
STEP 3. Sauté the spinach. In a large skillet, heat olive oil over medium heat. Add fresh spinach in batches, cooking until wilted, about 5 minutes. Transfer to a bowl and set aside.

STEP 6. Season the sauce. Stir in kosher salt, black pepper, paprika, and red pepper flakes. Cook until thickened, about 5-7 minutes.
STEP 7. Add cheeses. Reduce heat to low, then stir in cream cheese until melted and smooth. Gradually add Gruyere cheese, stirring well after each addition, followed by parmesan cheese.
STEP 8. Add spinach. Return the cooked spinach and its juices to the pan, stirring to combine.
STEP 9. Transfer to baking dish. Pour the mixture into an 8-by-8-inch baking dish and sprinkle with the topping mixture.
STEP 10. Bake. Place in the oven and bake for 30-35 minutes until bubbling and golden brown.
STEP 11. Rest before serving. Allow to sit for at least 10 minutes, then top with freshly grated lemon zest, if desired.
