This Sweet and Sour Pineapple Casserole is a fun blend of juicy pineapple, tangy flavors, and a crispy topping. It’s a delightful side dish that can brighten up any meal!
You’ll love how the sweetness and tang come together, and that crunchy topping? It’s like the cherry on top! I enjoy serving it at gatherings; it’s always a hit with everyone! 🥳
Key Ingredients & Substitutions
Crushed Pineapple: I love using canned crushed pineapple for its convenience. If you don’t have canned pineapple, fresh pineapple can work too, just make sure to chop it finely.
Pineapple Chunks: For texture, canned chunks are great, but feel free to swap with fresh chunks of pineapple for a more natural flavor.
Granulated Sugar: Regular sugar is perfect here, but you can use coconut sugar or a sugar substitute if you want to reduce calories while still keeping the sweetness.
Apple Cider Vinegar: This adds a nice tang. If you don’t have it, use white vinegar or lemon juice for a similar effect, but adjust the amount to taste.
Nuts: I enjoy using pecans or walnuts for a bit of crunch. If allergies are a concern or you prefer no nuts, simply leave them out without affecting the dish too much.
How Do I Ensure My Topping is Perfectly Crumbly?
Getting that topping just right can make the dish shine! To achieve a nice crumbly texture, start with room temperature butter. Cold butter can make the mixture too hard to crumble. Here’s how:
- In a bowl, mix brown sugar, melted butter, flour, and nuts until it resembles coarse crumbs.
- If the mixture feels too wet, add a little more flour until you get the right texture. You want it crumbly, not like dough!
- Sprinkle the topping generously over the pineapple, ensuring even coverage for the best texture and flavor.

How to Make Sweet and Sour Pineapple Casserole
Ingredients You’ll Need:
For The Casserole:
- 2 cans (20 oz each) crushed pineapple, drained (reserve juice)
- 1 can (20 oz) pineapple chunks, drained
- 1 cup granulated sugar
- 1 tablespoon cornstarch
- 1/4 cup apple cider vinegar (or white vinegar)
For The Topping:
- 1/2 cup brown sugar, packed
- 1/2 cup butter, melted
- 1 cup all-purpose flour
- 1 cup chopped pecans or walnuts (optional)
How Much Time Will You Need?
This delicious casserole takes about 15 minutes for prep and around 35-40 minutes for baking. Including a little time to cool before serving, you’ll have a scrumptious side dish ready in about an hour!
Step-by-Step Instructions:
1. Preheat and Prepare:
First, preheat your oven to 350°F (175°C). While it’s warming up, take a medium-sized casserole dish and grease it lightly so that the casserole doesn’t stick later on. This is an important step for easy serving!
2. Combine the Pineapples:
In a mixing bowl, combine the drained crushed pineapple and pineapple chunks. Now, add 1 cup of the reserved juice from the crushed pineapple can. This will keep your casserole moist and flavorful.
3. Sweeten It Up:
Add the granulated sugar into the pineapple mixture and stir well. You want to make sure that the sugar is mostly dissolved so that it blends nicely with the pineapples.
4. Mix in the Vinegar and Cornstarch:
In a smaller bowl, take the cornstarch and mix it with the apple cider vinegar until it’s smooth. This combination will help thicken the casserole. Pour this smooth mixture into the pineapple mix and stir well to combine everything.
5. Transfer to Casserole Dish:
Now, carefully transfer the pineapple mixture into the greased casserole dish, spreading it out evenly.
6. Make the Topping:
In another bowl, mix together brown sugar, melted butter, flour, and the chopped nuts (if you’re using them). Stir until the mixture is crumbly. This delicious topping will create a nice, sweet crunch!
7. Add the Topping:
Sprinkle the crumbly topping evenly over the pineapple mixture in the casserole dish. Make sure it’s well-covered for an even bake.
8. Bake to Perfection:
Place the casserole in the preheated oven and bake for about 35-40 minutes. Keep an eye on it – you want the topping to be golden brown and the pineapple mix to be bubbling around the edges. It’s hard to resist this delightful smell!
9. Cool and Serve:
Once done, remove the casserole from the oven and let it cool for just a few minutes. Serve it warm as a fantastic side dish and enjoy the sweet and sour flavors! It’s a sure crowd-pleaser!
Can I Use Fresh Pineapple Instead of Canned?
Absolutely! Fresh pineapple can be used for both the crushed and chunk pineapple. Just make sure to chop it finely for the crushed aspect and use juice from the fresh pineapple to replace the reserved juice.
What If I Don’t Have Cornstarch?
If you don’t have cornstarch, you can substitute it with all-purpose flour. Use about 2 tablespoons of flour instead of 1 tablespoon of cornstarch; it will still help thicken the mixture, although it might not be as effective.
How Should I Store Leftovers?
Store any leftovers in an airtight container in the refrigerator for up to 3 days. When you’re ready to eat, you can reheat it in the oven at 350°F (175°C) for about 10-15 minutes or until warmed through.
Can I Make This Casserole Ahead of Time?
Yes! You can prepare the pineapple mixture and topping separately a day in advance. Just store them in the fridge and assemble them before baking. Bake it fresh when you’re ready to serve for the best texture!
