It’s super easy to make, uses just a handful of ingredients, and somehow feels both homey and fancy at the same time. Let’s get cooking, shall we?
Why Pineapple Casserole Deserves a Spot on Your Table
So, here’s the thing: pineapple casserole is not your average side dish. It’s like a wild card that surprises everyone at the dinner table. Sweet pineapples and sharp cheddar cheese? Bold move. Then you toss in buttery crackers for crunch, and it’s game over.
This dish has that perfect balance of flavors and textures—creamy, cheesy, sweet, and crunchy—all in one bite. Think of it as a mashup between dessert and a savory side dish. People will ask for seconds, and they’ll definitely ask for the recipe.
Plus, it’s totally versatile. Serve it as a side dish with ham, turkey, or chicken. (Trust me, it pairs ridiculously well with holiday hams). Or, if you’re like me, just eat it straight out of the dish when no one’s watching. No judgment here.
Ingredients for the Best Pineapple Casserole
Before we dive into the steps, let’s talk ingredients. The beauty of this recipe is how simple it is—you probably already have most of this stuff in your pantry or fridge.
Here’s what you’ll need:
- 2 (20-ounce) cans of pineapple chunks, drained
- (Keep the juice—it’ll come in handy!)
- 1 cup granulated sugar
- (Don’t worry, it’s not too sweet, promise.)
- 6 tablespoons all-purpose flour
- (This helps thicken the whole thing.)
- 2 cups shredded sharp cheddar cheese
- (Sharp is key here. You want that bold cheesy flavor!)
- 1 sleeve of Ritz crackers (about 35 crackers), crushed
- (The buttery goodness of Ritz is non-negotiable here.)
- ½ cup unsalted butter, melted
- (Because, let’s face it, butter makes everything better.)

How to Make Pineapple Casserole
Alright, grab your casserole dish and let’s do this. The process couldn’t be easier—it’s basically just mix, layer, and bake.
Step 1: Preheat Your Oven
Set your oven to 350°F (175°C). You’ll want it nice and toasty by the time you’re done assembling everything.
Step 2: Mix the Pineapple Base
In a really big mixing bowl: take those drained pineapple chunks and toss them with sugar and flour. Give it a good stir until all the pineapple pieces are coated enough. That will be the base for your casserole.
Professional tip: If you want that extra zing, add a little reserved pineapple juice. It is not required to do so but gives the dish a nice little zing.
Step 3: Layer It Up
Grab a 9×13-inch baking dish and spread the pineapple mixture evenly across the bottom. Now, sprinkle the shredded cheddar cheese over the top. (Yes, cheese and pineapple together—it’s magic. Just trust me.)
Step 4: Add the Cracker Topping
In another bowl, mix up the crushed Ritz crackers with the melted butter. Swirl until the crackers are covered entirely with that glorious butter flavor. Then sprinkle it on that cheese layer because that’s where all of that addictive crunch comes from.
Step 5: Bake to Perfection
Now place the casserole into the preheated oven, and bake for about 25 to 30 minutes, or until the top is browned and bubbly. Do try not to look too much, because the aroma will be awesome!
Step 6: Serve and Enjoy
Let the casserole cool for about 5–10 minutes before serving. It’s best enjoyed warm, but honestly, it’s pretty delicious at room temperature, too.

Tips and Tricks for the Perfect Pineapple Casserole
- Use sharp cheddar cheese. Seriously, don’t go for mild here. The sharpness is what makes this dish so good—it balances out the sweetness of the pineapple.
- Drain the pineapple really well. Too much liquid will make your casserole soggy, and nobody wants that. Press out any extra juice if needed.
- Don’t skimp on the crackers. That buttery, crunchy topping is what ties the whole dish together. If you’re feeling extra, add a little sprinkle of brown sugar to the cracker mix for a touch of caramelized sweetness.
- Make it ahead. This casserole reheats beautifully, so you can prep it a day in advance if you’re hosting a big meal. Just assemble everything, cover it, and pop it in the fridge until you’re ready to bake.
- Get creative. Want to put your own spin on it? Try adding a pinch of cinnamon to the pineapple mixture or mixing in some crushed pecans with the crackers.
What to Serve with Pineapple Casserole
This dish pairs perfectly with just about any protein. Here are some classic combos:
- Holiday Ham: The sweet and savory combo is chef’s kiss.
- Jambalaya Soup: A great addition to a hearty Southern meal.
- Pulled Pork: The tangy pineapple adds a fun twist to a barbecue spread.
- Grilled Salmon: If you’re feeling fancy, the pineapple complements the rich, smoky flavor of salmon beautifully.

Or, if you’re like me, just grab a spoon and call it dinner.

Storing and Reheating Pineapple Casserole
If you’re lucky enough to have leftovers (and that’s a big if), here’s how to store and reheat this beauty:
Storing:
- Transfer the casserole to an airtight container or cover it tightly with plastic wrap.
- Store it in the fridge for up to 3–4 days.
Reheating:
- Preheat your oven to 350°F (175°C).
- Pop the casserole into a baking dish (if it’s not already in one) and bake for 10–15 minutes until warmed through. If the cracker topping seems a little soft, uncover it for the last 5 minutes to crisp it back up.
- If you’re in a hurry, you can microwave individual portions, but keep in mind that the topping won’t stay as crunchy.

Fun Variations to Try
Pineapple casserole is one of those recipes that invites creativity. Once you’ve mastered the classic version, try one of these twists:
- Tropical Style: Add shredded coconut to the cracker topping and a splash of coconut milk to the pineapple mixture. It’ll feel like a mini tropical vacation.
- Spicy Kick: Mix in a pinch of cayenne or red pepper flakes to the pineapple mixture for a subtle heat that cuts through the sweetness.
- Nutty Twist: Stir in some chopped pecans or walnuts with the cracker topping for a nutty crunch.
- Bacon Lovers’ Dream: Sprinkle cooked, crumbled bacon over the top after baking. Pineapple and bacon are a match made in heaven.
- Dessert Upgrade: Turn this dish fully into a dessert by adding a crumble topping and serving it with a scoop of vanilla ice cream.

FAQ About Pineapple Casserole Recipe
Can I freeze pineapple casserole?
You technically can, but I wouldn’t recommend it. The texture of the crackers can get a little soggy after freezing and thawing. It’s best enjoyed fresh or refrigerated for a few days.
Can I make this gluten-free?
Yes! Use a gluten-free flour substitute and swap the Ritz crackers for a gluten-free alternative. There are plenty of buttery cracker options out there that will work just as well.
What cheese works best?
Sharp cheddar is the gold standard here. Its bold flavor stands up to the sweetness of the pineapple. Mild cheddar or other cheeses won’t give you the same magic combo.
Can I make it less sweet?
But you could really reduce the sugar maybe down as far as to about 1/2 cup for 1 cup, or even leave it out altogether, because it is probably sweet enough for most people. The pineapple is naturally sweet for a lot of people.
Now you’ve got everything you need to prepare the ultimate pineapple casserole.

Why Pineapple Is More Than Just Delicious
Before we wrap things up, let’s take a second to talk about why pineapple is such a superstar ingredient—not just for its flavor but for its health benefits too. Pineapples are packed with vitamin C, which helps boost your immune system, and they’re a great source of bromelain, a natural enzyme that aids digestion. Plus, they’re low in calories and high in antioxidants, making them a guilt-free addition to your meals.
