Ingredients

Here’s what I use for this recipe and each ingredient plays an important role in the final texture and flavor and you can always make substitutions if needed.

Pineapple chunks: Provide sweetness moisture and the signature tropical flavor that defines the casserole.
Pineapple juice: Helps bind the mixture and reinforces the pineapple flavor throughout the dish.
Granulated sugar: Enhances sweetness and balances the savory elements without overpowering them.
All purpose flour: Thickens the filling so the casserole sets properly while baking.
Sharp cheddar cheese: Adds a savory contrast that keeps the dish from being overly sweet and creates richness.
Buttery crackers: Form the crunchy topping that adds texture and a familiar comforting finish.
Unsalted butter: Brings everything together in the topping and helps it brown evenly in the oven.

Tools You’ll Need

Mixing bowl: Used to combine the pineapple base ingredients evenly and comfortably.
Fine mesh strainer: Helps drain excess pineapple juice so the casserole does not become watery.
Rubber spatula: Makes folding the ingredients together easy without crushing the pineapple chunks.
Baking dish: Holds the casserole during baking and allows even heat distribution.
Small bowl: Used to mix the cracker topping with melted butter before adding it on top.
Oven: Bakes the casserole until bubbly and golden with the right balance of soft and crisp textures.

Instructions

Step 1 Prepare the pineapple mixture

I start by draining the pineapple chunks using a fine mesh strainer and I make sure to reserve the juice because it will be used later in the mixture. In a large mixing bowl I combine the drained pineapple chunks with sugar flour and a portion of the reserved pineapple juice and I gently stir until everything is evenly coated and lightly thickened without breaking up the fruit.

Step 2 Add the cheese

I fold the shredded sharp cheddar cheese into the pineapple mixture using a spatula and I take my time here to make sure the cheese is distributed throughout because this is what gives the casserole its signature sweet and savory balance once baked.

Step 3 Assemble the casserole

I lightly grease my baking dish and then spread the pineapple and cheese mixture evenly across the bottom making sure it is level so it bakes evenly from edge to center.

Step 4 Make the topping

In a small bowl I crush the buttery crackers into coarse crumbs and then mix them with melted butter until all the crumbs are coated which helps them bake up crisp and golden rather than dry.

Step 5 Top and bake

I sprinkle the buttery cracker topping evenly over the casserole and then place the dish into a preheated oven where I bake it until the filling is bubbly around the edges and the top is golden brown and fragrant which usually takes just under half an hour.

Step 6 Rest before serving

Once baked I let the Pineapple Casserole rest for a few minutes before serving because this allows the filling to set slightly and makes it easier to scoop clean portions.

Tips

From my experience this casserole works best when the pineapple is well drained so I always take an extra minute to let it sit in the strainer. I also prefer sharp cheddar because mild cheese can get lost against the sweetness of the pineapple. If you want extra crunch I sometimes add a few more crushed crackers on top during the last few minutes of baking and if the top browns too quickly I loosely cover it and finish baking gently.

Ways to Serve

I like serving Pineapple Casserole warm alongside baked ham roasted chicken or pork dishes because the sweetness complements savory mains beautifully. It also works well as part of a holiday spread where guests expect a mix of classic comfort sides. For brunch or casual gatherings I sometimes serve it slightly cooled where it holds its shape better and can even be enjoyed as a dessert style side with coffee.

Storage Instructions

After the casserole has cooled completely I store leftovers in an airtight container in the refrigerator where it keeps well for several days. When reheating I prefer using the oven or toaster oven to help restore the crisp topping rather than the microwave which can soften it too much. If needed it can also be frozen tightly wrapped and reheated later for convenience.
