Preheat your oven to 350˚F. Butter an 8x8 baking dish, ensuring even coverage to prevent sticking.
Thoroughly drain the pineapple chunks and set aside ⅓ cup of the juice. In a medium bowl, mix the sugar, flour, salt, and reserved pineapple juice until smooth.
Add the drained pineapple chunks to the bowl, mixing well to coat. Transfer the mixture to the prepared baking dish and sprinkle the shredded cheddar cheese evenly over the top.
Coarsely crush the Ritz crackers and combine with the melted butter, mixing until well coated. Spread this cracker mixture evenly over the pineapple and cheese layer in the baking dish.
Place the casserole in the preheated oven and bake for 30 minutes, or until it’s hot, bubbly, and the top is golden brown. Enjoy!
Notes
Drain thoroughly to avoid a soggy casserole.
Use sharp cheddar cheese for the best flavor contrast with the sweet pineapple.
For maximum crunch, crush the crackers right before using.
Serve this casserole fresh from the oven for optimal taste.
