Prepare the Green Beans

  2. Mix gently to coat evenly.
  3. Stir in half of the crispy onions for added crunch inside the casserole.
Bake the Casserole

  2. Cover the baking dish with foil and bake for 25 minutes.
Add the Final Topping & Finish Baking
  1. Remove foil and sprinkle the remaining crispy onions on top.

Rest & Serve
