This southern 5-ingredient pineapple casserole is one of those church-potluck, Easter-at-Mama’s-house kind of recipes that disappears the minute it hits the table. It’s the perfect mix of sweet and savory: warm, buttery pineapple bubbling up under a crispy cracker topping with just enough sharp cheddar to keep it from being dessert. This is classic Southern comfort, the kind of dish that gets passed around with everyone asking, “Who made this? I need the recipe.” It’s simple enough for a busy weeknight but special enough for holidays and family gatherings.
Serve this pineapple casserole warm, scooped onto a white plate so you can see the golden, buttery cracker crust over the gooey fruit and melted cheese. It pairs beautifully with ham (especially at Easter), roasted or fried chicken, pork chops, or even a simple grilled sausage. I like to round out the meal with something green—like steamed green beans or a simple salad—and a pan of cornbread or dinner rolls. For potlucks, I bring it in a baking dish and keep a serving spoon handy; it holds well on a buffet and tastes just as good at room temperature as it does straight from the oven.
Southern 5-Ingredient Pineapple Casserole
Servings: 8

Ingredients
2 (20-ounce) cans pineapple chunks in juice, well drained
1 cup granulated sugar
1 cup shredded sharp cheddar cheese, packed
1 sleeve (about 30) buttery round crackers, crushed
1/2 cup (1 stick) unsalted butter, melted
Directions
Preheat your oven to 350°F (175°C). Lightly grease a 2-quart baking dish (an 8x8-inch or similar size works well).
Drain the pineapple chunks very well, pressing gently with the back of a spoon in the strainer to remove excess juice. Too much liquid will make the casserole soupy instead of bubbly and thick.
In a medium mixing bowl, stir together the drained pineapple, granulated sugar, and shredded sharp cheddar cheese until everything is evenly combined and the pineapple is coated.
Spoon the pineapple mixture into the prepared baking dish and spread it into an even layer so it bakes uniformly.
In a separate bowl, crush the buttery round crackers by hand or with the bottom of a glass until you have coarse crumbs—think pea-sized pieces, not fine dust. Pour the melted butter over the cracker crumbs and stir until all the crumbs are evenly coated and look glossy.
Sprinkle the buttery cracker mixture evenly over the pineapple layer, covering it from edge to edge so you get a crispy bite in every spoonful.
Bake the casserole in the preheated oven for 25–30 minutes, or until the topping is golden brown and crisp and you can see the pineapple and cheese mixture bubbling up around the edges.
Remove from the oven and let the casserole rest for about 5–10 minutes before serving. This helps it set up a bit while still staying warm and gooey. Serve scooped onto plates so you can see that bubbly fruit, melted cheese, and crispy cracker topping all together.
Variations & Tips
For families with picky eaters, you can swap pineapple chunks for pineapple tidbits or crushed pineapple so there aren’t big pieces of fruit—kids often like the smoother texture. If you prefer it a little less sweet, cut the sugar down to 3/4 cup or even 1/2 cup, especially if your pineapple is very sweet. For more of that sweet-and-savory contrast, use extra-sharp cheddar or mix in a bit of white cheddar with the yellow. If you only have salted butter, you can still use it; just know the topping will have a slightly saltier, snacky flavor that many people love. To make it ahead, assemble the pineapple, sugar, and cheese in the dish, cover, and refrigerate up to a day. Wait to mix and add the cracker-butter topping until just before baking so it stays crisp. You can also double the recipe and bake it in a 9x13-inch dish for big gatherings—just keep an eye on the baking time and add 5–10 minutes if needed until the top is deeply golden and the edges are bubbling.
