This pineapple casserole recipe is the side dish that makes people ask “wait, what is in this?” and then go back for seconds. Sweet, juicy pineapple is baked in a lightly thickened, cheesy sauce under a golden, buttery cracker topping. It sits somewhere between a side dish and a dessert, and that is exactly why it works next to ham, turkey, and barbecue.
If you have never made pineapple casserole, cheese and pineapple together may sound odd. Trust the Southern potluck tradition. Sharp cheddar balances the sweetness, and the buttery cracker crumbs add salty crunch. This easy pineapple casserole takes 10 minutes of prep and just one baking dish.
I first tried pineapple casserole at a family potluck years ago, and I honestly did not expect to like it. One bite of that sweet, cheesy filling under the salty cracker crumbs and I was asking for the recipe before dessert was even served. Now it is the dish I bring whenever someone asks me to bring a side.
Quick facts: This pineapple casserole recipe takes 10 minutes of prep, 25 to 30 minutes in the oven, and serves 8.

Ingredients for Pineapple Casserole
The ingredient list for this easy pineapple casserole is short and humble. Use pineapple packed in juice rather than heavy syrup, and keep the juice, because a few spoonfuls of it make the sauce.
- 2 cans (20 oz each) pineapple tidbits or chunks in juice: drained, with 3 tablespoons of the juice saved.
- ½ cup granulated sugar: sweetens the filling and helps it thicken.
- ¼ cup all-purpose flour: thickens the juice into a light sauce.
- 1½ cups shredded sharp cheddar cheese: sharp cheddar balances the sweetness best.
- 1 sleeve buttery round crackers: about 1 to 1¼ cups crushed, such as Ritz.
- 4 tablespoons unsalted butter, melted: for the crunchy topping.
Ingredient Notes
- Pineapple: Tidbits or chunks work best. Crushed pineapple holds too much liquid and makes the casserole runny.
- Cheese: Shred your own if you can. Freshly shredded cheddar melts smoother than the pre-shredded kind.
- Crackers: Buttery round crackers are the classic choice. For a lighter crunch, swap in panko mixed with the melted butter.
How to Make Pineapple Casserole
Here is the step by step pineapple casserole recipe. Mix, spread, top, and bake.
Mix the Filling
Preheat the oven to 350°F (175°C) and grease a 2 quart baking dish (an 8×8 or 9×9 inch dish works). In a large bowl, whisk the sugar and flour together. Stir in the 3 tablespoons of reserved pineapple juice until it forms a smooth paste, then fold in the drained pineapple and the cheddar.
Fill the Dish
Spread the pineapple mixture into the prepared dish in an even layer. The filling will look thick and a little dry at this point. That is exactly right, the pineapple releases juice as it bakes.
Add the Buttery Topping
Crush the crackers into coarse crumbs, leaving some pea-sized pieces for crunch. Stir them with the melted butter in a small bowl until every crumb is coated, then sprinkle evenly over the pineapple.
Bake Until Golden
Bake for 25 to 30 minutes, until the topping is golden and the edges are bubbling. Rest the casserole for 10 minutes before serving so the sauce can thicken and settle.
Why This Pineapple Casserole Recipe Works
A few simple choices make this pineapple cheese casserole work. First, the flour and sugar. They turn a small amount of pineapple juice into a lightly thickened, glossy sauce instead of a watery pool.
Second, the sharp cheddar. Its tang cuts through the sweetness, which is the reason the dish tastes balanced rather than candy-like.
Third, buttering the crumbs separately. Tossing crackers with melted butter before they go on top coats each crumb, so they toast evenly and stay crunchy over the soft filling.
My Best Tips for Perfect Pineapple Casserole
- Drain well, then add back only a little juice. Too much juice leaves you with a soupy casserole.
- Keep the topping for last. If you assemble ahead, hold the crackers and butter until just before baking.
- Use a shallow dish. A thinner layer means more surface for the crunchy topping.
- Rest before scooping. Ten minutes lets the sauce set and gives you clean spoonfuls.
Easy Pineapple Casserole Variations
Less Sweet Version
Cut the sugar to ⅓ cup. The casserole still tastes sweet from the pineapple, and the cheese comes through even more.
Pecan Pineapple Casserole
Stir ½ cup chopped pecans into the cracker topping. They toast in the oven and add a rich, nutty crunch.
Gluten Free Pineapple Casserole
Replace the flour with 3 tablespoons cornstarch and use gluten free buttery crackers for the topping. Check the labels on your crackers.
Fresh Pineapple
You can use about 4 cups of fresh pineapple chunks, drained very well, in place of the canned. Fresh pineapple is juicier, so reserve less juice and drain it longer.
What to Serve With Pineapple Casserole
This is the classic side for baked ham, and it is just as happy beside roast turkey, pulled pork, or grilled chicken. For a full holiday plate, add my cornbread stuffing recipe, my cream corn casserole recipe, and my easy sweet potato casserole recipe. A crisp green salad or roasted green beans keep the plate balanced.
How to Store and Reheat Pineapple Casserole
In the Refrigerator
Refrigerate leftovers within 2 hours of serving, covered, and use them within 4 days, in line with the University of Tennessee Extension holiday leftovers guide. Reheat in a 350°F (175°C) oven for 15 to 20 minutes, until it reaches 165°F (74°C). Uncovering it for the last 5 minutes crisps the topping again.
Freezing
I do not recommend freezing the finished casserole, because the cracker topping turns soggy. If you want to prepare it ahead, freeze nothing and instead mix the filling a day early, then top and bake fresh.
Make Ahead
Mix the pineapple filling up to 1 day ahead, spread it in the dish, cover, and refrigerate. Add the buttered crumbs right before baking and add about 5 minutes to the bake time.
Final Thoughts
Pineapple casserole is one of those side dishes that sounds strange until you taste it, and then it becomes a requirement at the table. If this pineapple casserole recipe earns a spot on your holiday menu, I would love to hear about it in the comments.
Frequently Asked Questions
Is pineapple casserole sweet or savory?
Both. The pineapple and sugar make it sweet, while the sharp cheddar and buttery cracker topping make it salty and savory. That balance is why it works as a side dish next to ham and turkey.
Can I use crushed pineapple?
I do not recommend it. Crushed pineapple holds a lot of liquid and turns the casserole watery. Pineapple tidbits or chunks, drained well, give a much better texture.
Can I use fresh pineapple?
Yes. Use about 4 cups of fresh pineapple chunks, drained well, and reserve only 2 tablespoons of juice. Fresh pineapple is juicier, so the casserole may need an extra few minutes in the oven.
Why is my pineapple casserole watery?
Usually the pineapple was not drained well enough, or crushed pineapple was used. Drain the chunks thoroughly, use only the 3 tablespoons of reserved juice, and let the dish rest for 10 minutes before serving.
Can I make pineapple casserole ahead of time?
Yes. Mix and spread the filling up to 1 day ahead and refrigerate it covered. Add the buttered cracker topping just before baking so it stays crunchy.
What crackers are best for pineapple casserole?
Buttery round crackers like Ritz are the classic choice. Panko mixed with melted butter also works if you prefer a lighter, crispier topping.
What size dish do I need?
A 2 quart dish, such as an 8×8 or 9×9 inch baking dish, serves about 8 as a side. For a bigger crowd, double the recipe and use a 9×13 dish, baking a few minutes longer.
Can I make this pineapple casserole gluten free?
Yes. Use 3 tablespoons of cornstarch instead of the flour and a gluten free buttery cracker for the topping. Check the labels to be sure.
