This Sweet and Sour Pineapple Casserole is a fun dish that brings together the tangy taste of pineapple and a touch of sweetness. It’s like a tropical party in your mouth!
The best part? It’s super easy to make! I love serving it alongside grilled meats. It’s sweet, sour, and truly delightful—perfect for those who want to brighten up their dinner plate!
Key Ingredients & Substitutions
Pineapple: Using crushed pineapple adds moisture and flavor, while chunks give a nice texture. If fresh pineapple is hard to find, canned works great. Just make sure it’s in juice, not syrup, for the best flavor.
Mini Marshmallows: These bring a sweet softness to the dish. If you’re looking for a healthier option or avoiding certain ingredients, consider using chopped dates or dried fruits for sweetness without the marshmallows.
Sour Cream: This ingredient adds a tangy creaminess that balances the sweetness. You can swap in Greek yogurt for a healthier twist, which will still give you that creamy texture.
Buttery Cracker Crumbs: Ritz crackers are a favorite for their buttery flavor. If you’re vegan or want a gluten-free version, look for dairy-free crackers or crushed gluten-free options to keep the texture.
Butter: While melted butter is classic for the crumb topping, coconut oil or a plant-based butter can be a great alternative if you’re dairy-free.
How Do I Ensure a Perfectly Crisp Crumb Topping?
The crumb topping is key to the casserole’s texture. To get it just right, make sure to blend the cracker crumbs with melted butter thoroughly. This helps them stick together and achieve that golden brown look in the oven.
- Combine the melted butter and crumbs well; it should resemble wet sand.
- Evenly spread the crumb mixture on top of the pineapple layer in the dish. This ensures even cooking.
- Keep an eye on your casserole towards the end of baking. If it’s browning too fast, cover it lightly with foil to prevent burning.

How to Make Sweet And Sour Pineapple Casserole
Ingredients You’ll Need:
For the Casserole:
- 2 cups crushed pineapple (with juice)
- 1 cup pineapple chunks (fresh or canned)
- 1 cup mini marshmallows
- 1 cup sour cream
- 1/4 cup sugar
- 1/2 teaspoon vanilla extract
For the Topping:
- 1 cup buttery cracker crumbs (like Ritz crackers), crushed
- 1/4 cup butter, melted
- Maraschino cherries, for topping (about 4-5)
How Much Time Will You Need?
This delightful casserole will take about 10 minutes to prepare and around 30-35 minutes to bake. Overall, you’re looking at about 45 minutes from start to finish, which includes a little time to let it cool before serving.
Step-by-Step Instructions:
1. Preheat and Prepare:
Start by preheating your oven to 350°F (175°C). Grab a medium baking dish and lightly grease it with cooking spray or a little butter to keep the casserole from sticking.
2. Mix the Pineapple Base:
In a large bowl, mix together the crushed pineapple (make sure to include the juice), pineapple chunks, mini marshmallows, sour cream, sugar, and vanilla extract. Be gentle while mixing to keep the marshmallows intact. Once it’s all well blended, it should look creamy and fruity!
3. Spread into the Baking Dish:
Pour the pineapple mixture into the greased baking dish. Use a spatula to spread it out evenly so every bite gets that sweet flavor.
4. Make the Crumb Topping:
In a separate small bowl, combine the crushed buttery cracker crumbs with the melted butter. Stir until the crumbs are nicely coated with the butter. This will make your topping crispy and delicious!
5. Add the Topping:
Sprinkle the crumb mixture evenly over the top of the pineapple mixture in the baking dish. Make sure to cover it all for a lovely, crunchy finish.
6. Bake to Perfection:
Place the dish in the preheated oven and bake for about 30-35 minutes. You want the topping to be golden brown and the casserole to be bubbly around the edges. Look for those signs to know it’s ready!
7. Garnish with Cherries:
Once baked, pull the casserole out of the oven. While it’s still warm, arrange the maraschino cherries on top for a fun and colorful decoration.
8. Cool and Serve:
Let the casserole cool for about 10 minutes before serving. It can be enjoyed warm or at room temperature, making it a versatile dish for any meal!
This Sweet And Sour Pineapple Casserole is a comforting side dish that strikes a perfect balance between tangy pineapple, creamy goodness, and a deliciously crispy topping, all topped off with bright cherries. Enjoy every bite!
Can I Use Fresh Pineapple Instead of Canned?
Absolutely! Fresh pineapple adds a great texture and flavor. Just make sure to cut it into small chunks and remove the core for the best results.
How Can I Make This Recipe Gluten-Free?
To make this casserole gluten-free, simply substitute the buttery cracker crumbs with gluten-free crackers or even crushed gluten-free cereal. Just check labels to ensure they meet your dietary needs!
Can I Prepare This Casserole Ahead of Time?
Yes! You can mix the pineapple filling and crumb topping separately and store them in the fridge for up to a day in advance. Just assemble and bake right before serving for best results.
What’s the Best Way to Store Leftovers?
Store any leftovers in an airtight container in the fridge for up to 3 days. To reheat, simply microwave individual portions or warm in the oven at 350°F (175°C) until heated through.
