Pineapple Casserole is a sweet and savory side dish featuring crushed pineapple, pineapple chunks, cheddar cheese, and Ritz crackers. It’s a fun and easy addition to any holiday dinner!

This simple casserole has long been a family favorite.

Why I Love This Pineapple Casserole Recipe

Only 6 ingredients. One of my favorite things about this recipe is that there are only 6 ingredients, most of which I usually have on hand. It’s an easy side dish to whip up anytime.

Recipe Ingredients

Here’s on overview of the six ingredients in the casserole. Scroll down to the recipe card below for the exact measurements.

Pineapple – I use both crushed pineapple and pineapple chunks in this casserole. Both should be drained but reserve 1/4 cup of juice from the pineapple chunks.
Granulated sugar – Helps balance the acidity of the pineapple.
All-purpose flour
Cheddar cheese – Sharp cheddar works best, but you can use mild cheddar or a mix of cheddar and mozzarella for a milder flavor.
Ritz crackers – Adds a crispy topping to the casserole.
Unsalted butter – Substitute melted coconut oil or margarine for butter if needed.

How To Make Pineapple Casserole

This casserole takes just a few minutes to prep! The printable instructions can be found in the recipe card below.

Prep. Preheat the oven to 350F. Grease the baking dish.
Combine the ingredients. Add the crushed pineapple, pineapple chunks, and reserved juice to a bowl. Stir in the sugar and flour until well wcombined. Fold in the shredded cheese. Transfer to the baking dish in an even layer.
Add the topping. Combine the Ritz cracker crumbs and butter. Evenly sprinkle over the pineapple mixture.
Bake. Bake for 25-30 minutes. The top should be golden and the edges bubbling. Cool for 5 minutes then serve.

Tips & Variations

Here are a few general tips for this pineapple casserole and a few ways to customize it.

Stir in some nuts. Add 1/2 cup of chopped pecans or walnuts to the topping for extra crunch.
Make it less sweet. Reduce the sugar to 1/4 cup if you prefer a less sweet casserole.
Drain the pineapple. Be sure to drain both the crushed pineapple and pineapple chunks well, reserving just 1/4 cup of juice. Otherwise the casserole will be too mushy.
Use a 9×9 pan. This recipe is for a 9×9 pan. An 8×8 pan would probably work, with a slightly longer bake time, but a regular cake pan would be too large.

Serving Suggestions

While it’s not as traditional as green bean casserole or sweet potato casserole, this pineapple casserole makes a regular appearance on our holiday tables. It also pairs perfectly with any ham or turkey dinner throughout the year.

How To Store & Reheat Leftovers

Fridge. Store leftover pineapple casserole in an airtight container in the refrigerator for up to 3 days.
Reheat. Reheat in a 350°F (175°C) oven for 10-15 minutes or in the microwave in 30-second intervals until warmed through.
