A beloved Southern classic, this pineapple casserole combines the sweetness of pineapple with the sharpness of cheddar cheese and a crispy, buttery Ritz cracker topping. It's a nostalgic dish often served at family gatherings, potlucks, and holiday feasts.
**Preheat Oven**: Set oven to 350°F (175°C). Grease a 2-quart baking dish.

**Layer Ingredients**: Pour the pineapple mixture into the prepared baking dish. Sprinkle shredded cheddar cheese evenly over the top.
**Make Cracker Topping**: In a separate bowl, combine crushed Ritz crackers with melted butter. Spread evenly over the cheese layer.
**Bake**: Place the casserole in the oven and bake for 30-35 minutes or until the top is golden brown and the edges bubble.
**Cool and Serve**: Let the casserole sit for 10-15 minutes before serving. Serve warm as a side dish or dessert.
