A classic sweet and savory casserole made with pineapple chunks, sharp cheddar cheese, and a buttery cracker topping. This recipe is gentle, forgiving, and written for beginners, with clear cues so the casserole sets properly and scoops cleanly every time.
This casserole can be assembled a few hours ahead and baked just before serving, but add the cracker topping right before baking to keep it crisp. Sharp cheddar works best for balance, but a milder cheese can be used for a softer flavor. If the casserole seems loose straight from the oven, allow it to rest longer, it will continue to thicken as it cools slightly.
