Ingredient Checklist


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

  • 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.

  • 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.

  • 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.

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

I love spinach so I love finding new ways of eating it. I enjoyed this recipe. It does not reheat great so since I'm the only one in the house who loves spinach I'll be sure to make less. For some reason the onion/flour mixture didn't make a paste it ended up being just onion coated in flour. Not sure what I did wrong there but the recipe came out just fine anyway. Read More

The recipe was good. I washed the spinach and the remaining water on the leaves caused there to be too much liquid in the spinach phase. I should have drained the spinach at that point. Read More
