Hot, cheesy baked pineapple casserole is an old Southern favorite for holidays! It's the perfect blend of sweet and savory in an easy-to-make side dish.
Preheat oven to 350 degrees and grease a 9x13 baking pan/casserole dish.
In a large bowl stir together crushed pineapple, pineapple chunks, sugar, flour, and cheese. Spread mixture into prepared baking dish. Sprinkle crushed crackers over the top, then drizzle with melted butter.
Bake for 20-25 minutes until mixture is bubbly and topping is browned. Allow to sit for 5-10 minutes, top with cracked black pepper and serve.
