Tips for the Best Green Bean and Corn Casserole
Make the best corn and green bean casserole with these tips!
- I like to add slivered almonds to the top of my casserole, but you can omit them if you’d like and just stick with the crackers. I find that the almonds lend a great crunchy and chewy texture to the topping.
- Remember to drain those mushrooms, green beans, and corn! You don’t want a diluted, watery casserole.
- For the best flavor and consistency, grate the cheddar cheese right off the block. It can be white or yellow since they have the same flavor. Only the colors are different!
Storage: You can keep this casserole in an airtight lid in the fridge for up to 4 days.
Reheating: Guess what? Your leftovers will reheat just fine in the microwave in 30 second intervals unti warmed through!
Freezing: This casserole freezes well without the cracker topping. After it’s baked and cooled, wrap it in a layer of plastic wrap followed by a layer of aluminum foil. It stays fresh in the freezer for up to 2 months. Just make sure it doesn’t have any crackers on top, otherwise they’ll get soggy.
What kind of crackers should I use?
Butter crackers taste the best! A sleeve of Ritz crackers or anything similar to them will work.
Why do I need to grate the cheese?
Bagged shredded cheese is covered in anti-caking powder that prevents the cheese from sticking to itself and clumping. That will affect the consistency of the casserole.
