To begin making Pineapple Casserole I put some Schar gluten free entertainment crackers into a ziplock bag.

Then used a rolling pin to crush them up finely.

Next I drained a can of pineapple tidbits; but I reserved ¼ cup of the juice.

I put the tidbits, reserved juice, a drained can of crushed pineapple, some shredded cheddar cheese, granulated sugar and a bit of Bob's Red Mill 1 to 1 gluten free baking flour into a large mixing bowl.

Then I stirred all of those ingredients together until they were well combined.

Next I scraped the pineapple mixture into a 1 ½ quart casserole dish.

I melted some butter in the microwave.

Then I put the crushed crackers and melted butter into a small bowl.

I used a fork to get all the cracker crumbs coated in the melted butter.

Next I sprinkled the crumbs on top of the pineapple mixture.

I placed the casserole in the preheated 350F oven for 30 minutes or until golden brown.

Remove from the oven.

How do I store pineapple casserole?

Pineapple casserole stores very well, making it a great make-ahead or leftover dish. Here’s how to keep it fresh and tasty:

Refrigerating (Best Method)
Let the casserole cool completely before storing.
Cover the baking dish tightly with plastic wrap or foil, or transfer to an airtight container.
Store in the refrigerator for 3–5 days.
Reheat individual portions in the microwave or warm the whole dish in the oven at 325°F (165°C) until heated through.

Freezing (For Longer Storage)
Pineapple casserole can be frozen, but it’s best frozen before baking for best texture.
Assemble the casserole, wrap tightly in plastic wrap and foil, and freeze for up to 2–3 months.
When ready to use, thaw overnight in the fridge and bake as directed.
If freezing leftovers after baking, note that the topping may soften slightly but will still taste good.

Reheating Tips
Reheat in the oven to help restore the crispy topping.
Cover loosely with foil to prevent over-browning, then remove foil for the last few minutes.
Microwave works for quick portions, but the topping will be softer.

Make-Ahead Tip
You can assemble pineapple casserole a day in advance and store it unbaked in the fridge.
Just add the cracker topping right before baking for the best crunch.
