Salt to taste
Pour into a greased 9 X 13 baking dish.
Add Topping: In a medium-sized bowl, mix melted butter, crushed cornflakes, and sliced almonds to combine. Spread the cornflake mixture evenly over the top of the casserole and spread evenly.NOTE - Pan Fry Topping (alternate topping instructions): In a frying pan, melt butter over medium-low heat. Add cornflakes and almonds to the pan to the melted butter and toast for about 2 minutes (stirring often). You don’t want them to get overly golden, as they will also bake in the oven.
1 stick of butter, 1 ½ to 2 cups crushed cornflakes, ½ cup sliced almonds
Bake for 25 - 30 minutes or until bubbly and golden. Serve warm.
Notes
Many people love a cheesy version. Add a cup of shredded cheddar or Monterey jack cheese to the filling.
