How to Make It
Making pineapple casserole is as simple as mixing, layering, and baking. Start by draining your pineapple chunks or tidbits thoroughly. Combine the pineapple with sugar and flour in a mixing bowl to create the base. Next, layer this sweet mixture into a baking dish, then sprinkle sharp shredded cheddar cheese over the top.
To finish, mix crushed buttery crackers with melted butter to create the topping. Spread it evenly across the cheese layer, giving the casserole its signature golden, crispy crust. Bake the dish in a preheated oven until bubbly and browned on top. Allow it to cool slightly before serving to let the flavors meld together beautifully.
Step by Step
Prepare the Pineapple Mixture
Begin by thoroughly draining two cans of pineapple chunks or tidbits to prevent the casserole from becoming soggy. In a large mixing bowl, toss the drained pineapple with granulated sugar and a bit of flour. The sugar enhances the pineapple’s natural sweetness, while the flour thickens the juices during baking, creating a rich, glossy base.
Layer the Ingredients
Spread the pineapple mixture evenly in a greased baking dish. Top it with a generous layer of shredded sharp cheddar cheese. The cheese might seem like an odd pairing with pineapple, but trust the process—it’s the key to this casserole’s unique sweet-savory balance.
Make the Topping
Crush buttery crackers (like Ritz) into small pieces and toss them with melted butter in a separate bowl. This mixture creates the crispy topping that contrasts beautifully with the soft pineapple base. Spread the cracker topping evenly over the cheese layer, ensuring complete coverage.

Bake to Perfection
Bake the casserole in a preheated oven at 350°F (175°C) for 25-30 minutes, or until the top is golden brown and the pineapple juices are bubbling. Let it cool slightly before serving to allow the layers to set and the flavors to shine.
Make Ahead Method
This pineapple casserole is incredibly make-ahead friendly!
- Prep in Advance: Assemble the casserole up to the point of adding the cracker topping. Cover and refrigerate for up to 24 hours. Add the topping just before baking to keep it crisp and fresh.
- Freezing Option: You can also freeze the assembled casserole (minus the topping) for up to 1 month. Thaw it overnight in the fridge, add the topping, and bake as directed.
- Reheating: Leftovers can be reheated in a 350°F oven until warmed through, or you can microwave individual portions for a quick treat.
Pro Tips
- Drain the Pineapple Thoroughly: Excess liquid can make the casserole watery, so don’t rush this step. Press the pineapple gently with a paper towel if needed.
- Use Sharp Cheddar: The bold flavor of sharp cheddar balances the sweetness perfectly. Mild cheddar works too, but the flavor will be less pronounced.
- Customize the Sweetness: For a less sweet dish, reduce the sugar by half or omit it entirely if your pineapple is very sweet.
- Experiment with Toppings: Swap out crackers for panko breadcrumbs or add a sprinkle of shredded coconut for extra flair.
- Serve Warm or Room Temperature: Pineapple casserole tastes amazing both hot and at room temperature, making it versatile for various settings.

Storage Options
- Refrigerator: Store leftovers in an airtight container for up to 3 days.
- Freezer: Freeze the baked casserole for up to 1 month. Wrap it tightly in foil and place it in a freezer-safe container. Thaw in the fridge before reheating.
- Reheating: Reheat in the oven at 350°F for 10-15 minutes to restore the crisp topping.
