This old-fashioned Southern casserole is one of those surprising recipes that wins people over with the first bite. Sweet pineapple, sharp cheddar, and buttery crackers may sound unusual together, but the combination bakes into a rich, tangy, spoonable side dish that has been beloved on holiday tables and Sunday suppers for generations. Its mid-century charm is part of the appeal, and with just a handful of pantry staples, it comes together so easily it feels almost too simple.
Serve this warm alongside baked ham, roast pork, turkey, or fried chicken, where its sweet-savory character balances salty, hearty mains especially well. It also fits naturally on a brunch buffet with sausage and egg dishes, and for a classic Southern-style spread, add green beans, a crisp salad, or roasted sweet potatoes to round out the plate.
Oven Baked 5-Ingredient Pineapple Casserole
Servings: 8
Ingredients
2 cans (20 ounces each) pineapple chunks, drained very well
1 cup granulated sugar
5 tablespoons all-purpose flour
A few tablespoons reserved pineapple juice
2 cups shredded sharp cheddar cheese
1 sleeve butter crackers, crushed
1/2 cup butter, melted
Directions
1. Preheat the oven to 350°F and lightly butter or grease a medium glass casserole dish.
2. Drain the pineapple chunks very well, reserving 2 to 3 tablespoons of the juice. This helps the casserole bake up saucy rather than watery.
3. In a large mixing bowl, stir together the sugar and flour, then mix in the reserved pineapple juice until the dry mixture is evenly moistened.
4. Add the drained pineapple and shredded cheddar to the bowl and fold gently until everything is evenly coated.
5. Spread the pineapple mixture into the prepared glass casserole dish in an even layer.
6. In a separate bowl, toss the crushed butter crackers with the melted butter until the crumbs are evenly coated, then sprinkle them over the top of the casserole.
7. Bake for 25 to 30 minutes, until the edges are bubbling and the cracker topping is deep golden brown.
8. Let the casserole rest for 5 to 10 minutes before scooping and serving warm.
Variations & Tips
Extra-sharp flavor: If you like a more pronounced sweet-savory contrast, use extra-sharp cheddar instead of regular sharp cheddar. It stands up especially well to the sweetness of the pineapple.
Make-ahead tip: Assemble the pineapple base and keep it covered in the refrigerator a few hours ahead of time. Add the buttered cracker topping just before baking so it stays crisp.
Texture tip: Crush the crackers into small pieces rather than fine crumbs. The slightly uneven texture gives the top a more rustic, crunchy finish.
Drain thoroughly: This is the most important step in the whole recipe. If the pineapple is not drained well, the casserole can turn thin and watery instead of pleasantly saucy.
Holiday serving idea: This dish is especially popular with baked ham at Easter, Thanksgiving, and Christmas, but it is easy enough for an everyday supper when you want something a little nostalgic on the table.
