How to Make Pineapple Casserole
This dish is a piece of cake to put together! Just follow these simple steps for a perfect casserole every time.
Step 1: Prep Your Oven and Dish
First things first, preheat your oven to 350°F (175°C). While it’s heating up, go ahead and lightly grease your 8×8-inch baking dish with some butter or non-stick spray to prevent any sticking.
Step 2: Mix the Pineapple Filling
In your mixing bowl, combine drained crushed pineapple and the pineapple tidbits. Add ½ cup granulated sugar, 6 tablespoons all-purpose flour, and ⅓ cup of the reserved pineapple juice.
Step 3: Add the Cheese
Now for the cheesy part! Gently stir in 1 ½ cups shredded sharp cheddar cheese until it’s all mixed together. Pour this entire mixture into your prepared baking dish and spread it out evenly.
Step 4: Prepare the Topping
In a separate small bowl, mix 1 ½ cups crushed Ritz crackers and ½ cup melted butter. Stir them until all the cracker crumbs are nicely coated in that buttery goodness.
Step 5: Bake to Perfection
Sprinkle the buttery cracker topping evenly over the pineapple and cheese mixture in the baking dish. Pop it into your preheated oven and bake for 25-30 minutes, or until the top is golden brown and bubbly.

Tips for the Best Pineapple Casserole
Here are a few of my tried-and-true tricks to make sure your casserole turns out perfectly every single time.
- Drain Pineapple Well. Make sure you drain the pineapple thoroughly to avoid a watery casserole.
- Use Sharp Cheddar. The strong flavor of sharp cheddar cheese really cuts through the sweetness.
- Don’t Overmix. Gently fold the ingredients together just until they are combined for the best texture.
- Freshly Shredded Cheese. Shredding your own cheese from a block melts much better than pre-shredded.
- Watch the Topping. Keep an eye on it while baking so the cracker topping doesn’t burn.
- Let It Rest. Let the casserole sit for about 10 minutes before serving to help it set.
Variations and Substitutions
Want to mix things up a bit? Here are some fun ideas to make this recipe your own.
- Add a Kick. Mix in a pinch of cayenne pepper or some diced jalapeños for a spicy twist.
- Try Different Crackers. Use crushed butter crackers like Town House or even breadcrumbs for the topping.
- Go Nuts. Add ½ cup of chopped pecans or walnuts to the topping for extra crunch and flavor.
- Cheese Please. Swap the cheddar for Monterey Jack, Colby, or even a blend of cheeses.
- Make it Creamy. For a creamier texture, you can stir in ¼ cup of sour cream or Greek yogurt.
Make-Ahead and Storage Tips
This baked pineapple casserole is a fantastic make-ahead dish, which is a lifesaver for holiday planning!
You can assemble the entire casserole a day in advance, but hold off on adding the cracker topping. Just cover the dish tightly with plastic wrap and keep it in the fridge. When you’re ready to bake, let it sit at room temperature for about 20 minutes, then add the fresh topping and bake as directed.
If you have leftovers, you can store them in an airtight container in the refrigerator for up to 3-4 days. The topping might lose some of its crunch, but it will still be delicious!

Recipe FAQs
Can I use fresh pineapple?
Definitely! Just make sure to chop it into small pieces. You’ll need about 4 cups of fresh pineapple for this recipe.
What is the best way to crush Ritz crackers?
The easiest way is to place them in a zip-top bag and crush them with a rolling pin. For a finer crumb, you can also pulse them a few times in a food processor.
Can I double this recipe?
Absolutely! Just double all the ingredients and bake them in a larger 9×13-inch baking dish. You might need to add a few extra minutes to the baking time.
Can I freeze this casserole?
I don’t recommend freezing this casserole, as the texture of the pineapple and the cracker topping can become soggy once thawed.
Why is my casserole watery?
This usually happens if the pineapple isn’t drained well enough. Make sure to press out as much juice as possible before mixing the ingredients.
Can I use a different kind of cheese?
For sure! While sharp cheddar is classic, feel free to experiment with Monterey Jack, Colby, or even a spicy pepper jack for a different flavor.
Is this dish served hot or cold?
This casserole is best served warm, straight from the oven. That’s when the cheese is melty and the topping is perfectly crunchy.
Can I make this recipe with less sugar?
You can reduce the sugar to ¼ cup if you prefer a less sweet dish. The pineapple already adds a lot of natural sweetness.
Can I use unsalted butter?
Yes, unsalted butter works just fine. If you use it, you might want to add a small pinch of salt to the cracker topping to balance the flavors.
What to serve with pineapple casserole?
It’s a fantastic side dish for baked ham, roasted turkey, or pulled pork. It also pairs well with other Southern classics like Southern Green Beans or Roasted Garlic Mashed Potatoes.
