Homemade Pineapple Casserole

Pineapple Casserole is such an unusual and delicious dish that I totally fell in love with after the first bite. If you like pineapple in savory recipes, you have to try this very easy vegetarian casserole. Sweet canned pineapple chunks are mixed with a bit of flour, sugar and lots of cheddar cheese.

Then, the mixture is topped with crushed Ritz crackers that have been mixed with melted butter. The end result is nothing short from amazing. Also, the sharp cheddar cheese compliments the juicy and sweet pineapple. Similarly, the brown sugar adds a deep caramel underdone, and the top gets buttery and crunchy.

My secret to making this easy casserole is to add a few simple ingredients that will take it up a notch. In addition, adding brown sugar works really well, as it caramelizes and it compliments the pineapple flavor. In addition, if you want to go all fancy, you can add just a little freshly grated nutmeg.

I like to add an extra layer of cheese, so there is cheese mixed with the pineapple, but also there is another top layer of cheese, on which the cracker crumb rest. Similarly, having that extra layer makes an outstanding casserole as the crackers baked into the melted cheese and create a cheesy, crunchy top that its impossible to resist. Adding more cracker topping is always a good idea as well.

The classic recipe is made with cheddar cheese, which I usually don’t substitute. However, if you would like to use something else, some great choices would be Tillamook, Longhorn, Double Glouster, Colby cheese. Also, you can even go for an agenda Gouda cheese.

How to store the Pineapple Casserole?

I like to wrap it in plastic wrap or to just cover it with foil and refrigerate. In addition, the casserole should only be kept at room temperature when served. It can be stored in the fridge for up to 5 days. Similarly, it can be served warm or cold, based on taste preference.

To reheat it, you can cover it with foil and put it in a hot oven for about 10 minutes. Also, you can microwave it in a microwave-safe bowl. I do not recommend freezing this casserole.
