Ingredients

Scale

For the Creamed Spinach:

  • 2 tablespoons unsalted butter
  • 1 large yellow onion, thinly sliced
  • 4 garlic cloves, minced
  • 1/2 teaspoon crushed red pepper flakes
  • 1/4 teaspoon freshly grated nutmeg
  • 2 tablespoons all-purpose flour
  • 3/4 cup heavy cream
  • 1 3/4 cups milk (2% or whole works best)
  • 1/2 cup grated parmesan cheese
  • 1/2 cup grated gruyere cheese
  • 3 (10-oz) packages of frozen spinach, defrosted and squeezed dry
  • Salt and pepper, to taste

For the Topping:

  • 1/2 cup grated gruyere cheese
  • 1 tablespoon unsalted butter, melted
  • 1 tablespoon olive oil
  • 1 teaspoon garlic powder
  • 1/2 teaspoon garlic salt
  • 1 cup panko breadcrumbs
  • 1/2 teaspoon kosher salt
  • 1 cup store-bought crispy fried onions

Instructions

For the Spinach:

  1. Preheat the oven to 425°F.
  2. Melt the butter in a large Dutch oven or pot over medium heat.
  3. Add the onion and cook for 5 minutes, or until it is beginning to soften.
    Stir in the garlic, red pepper flakes, and nutmeg and cook for another 5 minutes.
  4. Sprinkle the flour over the onion mixture and stir to combine. Cook for 1 minute to get rid of any raw flour taste.
  5. Slowly stream in the heavy cream and milk, whisking the entire time to incorporate. Bring to just below a simmer, stirring frequently, and cook for 2-3 minutes or until the milk and cream have thickened.
  6. Stir in the parmesan and gruyere cheeses until they are melted.
  7. Make sure your spinach is completely defrosted and squeezed dry of excess water. Add the spinach to the cream sauce and stir just to combine. Season with salt and pepper, to taste.
  8. Carefully transfer the mixture to a buttered baking dish.

For the Topping:

  1. Sprinkle the gruyere cheese over the top of the creamed spinach in the dish.
  2. In a bowl, combine the melted butter, olive oil, garlic powder, panko breadcrumbs, and salt. Toss to combine or until the breadcrumbs are evenly coated in the butter.
  3. Sprinkle the panko all over the top of the gruyere cheese. Sprinkle the crispy onions over top of the panko.

To Bake:

  1. Transfer the pan to the oven and bake for 15-20 minutes or until the top is golden and crisp and the edges are bubbly.
  2. Allow to cool slightly before serving.
