Ingredients

• 1 teaspoon salt
• 2 tablespoons all-purpose flour
• 3 tablespoons butter, melted
• 1 tablespoon olive oil
• 1 cup half-and-half
• 1 small onion, diced
• 0.5 teaspoon ground black pepper
• 0.5 teaspoon dried thyme
• 0.75 cup dry bread crumbs
• 1.5 pounds baby spinach, roughly chopped
• 1.5 cups shredded Swiss cheese, divided

Recipe Instructions

Step 1

Preheat the oven to 400 degrees F (200 degrees C).

Step 2

Heat oil in a large skillet over medium heat and cook onion until soft and translucent, about 5 minutes. Season with salt, pepper, and thyme. Sprinkle flour over onion mixture and cook until a thick paste forms, about 1 minute.

Step 3

Place spinach in a large soup pot and cover. Heat on low until spinach begins to wilt, about 4 minutes. Turn heat off and add half-and-half, 1 cup Swiss cheese, and the onion mixture. Stir to combine and transfer to a 9-inch gratin dish.

Step 4

Combine breadcrumbs and remaining 1/2 cup cheese in a bowl. Pour melted butter over the top and stir to combine. Evenly spread breadcrumb mixture over the spinach.

Step 5

Bake in the preheated oven uncovered for 20 minutes. Let cool for 5 minutes before serving.
