What Makes This Recipe So Good

  • It’s a total crowd favorite! Everyone will go insane for this cheesy, bubbly spinach casserole at your next holiday party or potluck. Don’t expect leftovers, and feel free to double the recipe if you’d like!

Key Ingredients

Frozen Spinach – With the help of frozen spinach, this side dish becomes even easier to assemble. Simply pick up two pounds of frozen spinach (2 16-ounce bags) from the store for this recipe. Then, to defrost the spinach, place it in a colander in the sink and run it under cold water. The frozen chunks will begin to break apart and in a few seconds your spinach will be completely defrosted. The last and most important step involves squeezing out as much moisture from your spinach as possible. Too much water in your casserole could result in a soupy, bland mess. Therefore, squeeze the thawed spinach in your hands allowing the water to drain out before adding it to the bowl with the rest of your ingredients.

Plain Breadcrumbs – Breadcrumbs give this cheesy spinach casserole an unexpected crunch! You can either toss all the breadcrumbs in with the casserole mixture, or reserve half of them for sprinkling on top. Be sure to use plain breadcrumbs, this casserole is flavorful enough and doesn’t need any extra seasoning – trust me!

Chef’s Tips

  • If you’d like, you can use fresh spinach instead! For fresh spinach, thinly slice three pounds then quickly sauté it in a skillet until wilted. Then, rinse and squeeze cooked spinach in a colander before using it in this recipe.
  • Feel free to top this cheesy spinach casserole with even more cheese if you’d like! A half cup of shredded cheddar cheese tastes delicious atop this side dish. If adding cheese, prepare the casserole as instructed before sprinkling desired cheese over the top and baking as instructed.
  • Add shredded chicken or leftover turkey for a complete meal! For a quick and easy dinner recipe, throw some pre-cooked and shredded meat in with the spinach mixture before baking. You’ll have a healthy, delicious, and wholesome dinner, ready in just 30 minutes!
