1-First Step: Preheat and prepare your baking dish Start by preheating your oven to 350°F. Lightly grease an 8×8-inch baking dish or a similar medium casserole dish. This helps the filling bake evenly and makes cleanup easier later. Having the oven ready before you mix the filling also keeps the process moving quickly, which is one reason this pineapple casserole recipe works so well for busy days.

2-Second Step: Mix the pineapple base In a large mixing bowl, add the drained pineapple chunks, the reserved 2 tablespoons of pineapple juice, sugar or brown sugar, flour, shredded cheddar cheese, cinnamon, and nutmeg. Stir gently until the pineapple is coated and the flour is evenly mixed in. You want the cheese to distribute throughout the fruit so each bite has a balance of sweet and savory flavor. Take a moment to scrape the sides and bottom of the bowl. Small pockets of dry flour can cause uneven texture, so a thorough stir now saves trouble later.

3-Third Step: Transfer the filling to the dish Spoon the pineapple mixture into the prepared baking dish and spread it into an even layer. Press it down just slightly with the back of a spoon so the filling sits level. This helps the casserole cook evenly and gives the topping a flat base to sit on. If you like a little extra sweetness in the finished dish, you can sprinkle a tiny pinch of sugar over the top before adding the cracker layer. It is optional, but some families love that extra hint of caramel-like flavor.

4-Fourth Step: Make the buttery cracker topping In a separate bowl, combine the crushed crackers with the melted butter. Stir until every cracker piece looks coated. The mixture should resemble damp crumbs, not dry flakes. This is the topping that gives southern pineapple casserole its comforting crunch, so make sure the butter reaches all the cracker pieces. Spread the topping evenly across the pineapple mixture. Do not worry if a few spots look uneven. As the casserole bakes, the butter will help the topping crisp up and brown beautifully.

5-Fifth Step: Bake until bubbly and golden Place the casserole in the oven and bake for about 25 to 30 minutes. You want the filling to be hot and bubbly around the edges, and the topping should look lightly browned and crisp. If your oven runs cool, it may need a few extra minutes. If the top begins browning too quickly, you can loosely cover it with foil for part of the baking time. For the best texture, let the casserole rest for 10 minutes after baking. That short wait gives the filling time to settle and makes serving much easier.

6-Final Step: Serve warm and enjoy Spoon the casserole onto plates or serve it straight from the dish while still warm. Pineapple casserole recipe lovers often serve it as a side dish with holiday ham, baked chicken, or pork, but it can also work as a sweet-savory addition to a brunch spread.
