Ingredients You’ll Need

3/4 cup granulated sugar: This sweetness enhances the natural flavor of the pineapple. If you’re looking for a substitute, consider coconut sugar for a deeper flavor.
1/3 cup all-purpose flour: This helps thicken the casserole while holding everything together. For a gluten-free version, try using almond flour.
1/2 tsp kosher salt: A pinch of salt balances the sweetness and enhances all the flavors.
2 20 oz cans of pineapple (sliced or in chunks): You can use either sliced or chunk pineapple based on your preference. Be sure it’s packed in juice for the best flavor and texture.
1/2 cup pineapple juice (reserved from cans): This juice keeps the casserole moist and flavorful. Don’t skip this step!
1 cup shredded sharp cheddar cheese: Aged cheddar brings a bold flavor to the dish, complementing the sweetness of the pineapple.
1/2 cup shredded cheddar cheese: This can be a medium or mild cheddar, whichever you prefer for added creaminess.
1 sleeve (about 30) buttery crackers (ritz): These crushed crackers create a crunchy topping; if you want a healthier version, you can use whole grain crackers.
6 tbsp unsalted butter (melted): This adds richness to the topping. If you want to make it dairy-free, consider using almond or coconut oil.

How to Make Pineapple Casserole

Preheat the Oven: Begin by heating your oven to 350°F. Prepare a 9×9-inch baking dish by greasing it lightly to prevent sticking.
Combine Dry Ingredients: In a large bowl, whisk together 3/4 cup granulated sugar, 1/3 cup all-purpose flour, and 1/2 tsp kosher salt until well combined.
Add Pineapple: Stir in the drained pineapple chunks (chopped if using slices) and the reserved 1/2 cup pineapple juice, ensuring everything is mixed thoroughly.
Mix in Cheese: Gently fold in both 1 cup of shredded sharp cheddar cheese and 1/2 cup of the shredded cheddar until the pineapple is evenly coated.
Pour into Dish: Transfer the pineapple mixture into your prepared baking dish, spreading it out evenly.
Prepare Topping: In a separate bowl, combine crushed buttery crackers with 6 tbsp of melted unsalted butter and the remaining 1/2 cup of shredded cheddar until the crackers are evenly coated.
Sprinkle Topping: Spread the cracker mixture over the casserole, ensuring an even layer across the top.
Bake: Place the casserole in the preheated oven and bake for 30 to 35 minutes, or until bubbly around the edges and the topping is golden brown.
Cool and Serve: Allow the casserole to cool for about 10 minutes before serving, as it will thicken as it sits.

Storing & Reheating

Store any leftovers covered in an airtight container at room temperature for a day or refrigerate for about 3 to 4 days. If freezing, use a freezer-safe container for up to 3 months. When reheating, pop it in the oven at 350°F for about 10-15 minutes until warmed through. Keep in mind that while the flavor remains delightful, the texture might become softer. Freshen it up by sprinkling some extra crushed cracker topping before reheating!

Chef’s Helpful Tips

Ensure your butter is melted but not too hot when combining with the crushed crackers, as this can make the topping soggy.
Don’t skip letting the casserole cool for a few moments before serving; this helps the flavors meld and the texture set.
For an extra layer of flavor, consider adding a sprinkle of cinnamon into the pineapple mixture!
Use room temperature dairy products when possible, as they blend more smoothly with the other ingredients.

Whether you serve it as a fun side dish at a summer barbecue or as part of a hearty comfort-food spread, this pineapple casserole is bound to impress. Each spoonful offers a unique taste experience, combining sweet and savory flavors that you and your guests will love. Feel free to experiment with the toppings or ingredients to make it your own—there’s no wrong way to enjoy this dish!
