10 Creative Ways to Use Up Leftover Green Bean Casserole

As a passionate home cook and food blogger, I love whipping up green bean casserole for holiday feasts. This comforting blend of tender green beans, creamy mushroom soup and crispy fried onions is a staple on many Thanksgiving and Christmas dinner tables.

But after everyone has had their fill, you’re often left with leftovers lingering in the fridge. If you’re wondering what to do with leftover green bean casserole have no fear! I’ve gathered 10 delicious ways to creatively transform those remnants into entirely new dishes.

1. Green Bean Casserole Frittata

One of my favorite ways to use up leftover green bean casserole is mixing it into a veggie-packed frittata. Just beat 6 eggs with salt, pepper and any other seasonings you like. Stir in 2 cups of chilled casserole and pour the mixture into a greased baking dish. Pop it in the oven at 375°F for 20-30 minutes until puffed and set. Easy, tasty and packed with protein!

2. Green Bean Casserole Quesadillas

Quesadillas are such a versatile and fast meal. Simply layer about 1/2 cup of leftover green bean casserole and 1/4 cup shredded cheese (I love cheddar or pepper jack) over half of a large flour tortilla. Fold it over and cook in a lightly oiled skillet until golden brown and melty on both sides.

3. Transform into a Creamy Green Bean Casserole Soup

Purée 2 cups of leftover green bean casserole with 4 cups of chicken or vegetable broth in a blender. Heat the mixture through and serve piping hot topped with a swirl of sour cream or Greek yogurt and a sprinkle of chives or crispy fried onions. It’s a comforting, cozy soup!

4. Mix Into Pasta for a Casserole Bake

For this easy pasta bake, simply combine 2 cups of cooked pasta and 1 cup of leftover green bean casserole. Transfer to a greased baking dish, top with shredded cheese and bake at 375°F until bubbly and golden on top. The crispy fried onions add great texture and flavor.

5. Use as Filling for Stuffed Peppers

Slice 4 bell peppers in half lengthwise, keeping the stems intact. Remove the ribs and seeds, and stuff each pepper half with about 1/2 cup of leftover green bean casserole. Top with shredded cheese and bake at 375°F for 20 minutes until the peppers are fork tender.

6. Fold Into an Omelet or Scrambled Eggs

Jazz up your morning eggs by folding chilled green bean casserole into an omelet or scrambling it with some beaten eggs. Just cook the eggs as usual, then spread the casserole over half of the omelet before folding it over, or stir it into the egg mixture before scrambling.

7. Make Green Bean Casserole Croquettes

For the perfect crispy, crunchy snack or appetizer, mix 2 cups of green bean casserole with 1 cup panko breadcrumbs. Shape into patties and pan fry in oil over medium heat until browned. Serve with ranch dressing or marinara sauce for dipping!

8. Transform Into Shepherd’s Pie

Make a rich, hearty shepherd’s pie by layering 2 cups of leftover casserole over cooked ground meat like beef, turkey or lamb in a baking dish. Top with mashed potatoes and bake at 375°F until the potatoes are crispy and browned on top, about 30 minutes.

9. Use as Filling for a Pot Pie

For the ultimate comfort food, spoon 2 cups of chilled green bean casserole into a pie dish. Top with a sheet of puff pastry, pressing to seal. Cut slits in the top and bake at 400°F until the pastry is golden brown, about 25 minutes. Simple and delicious!

10. Make Green Bean Casserole Rice

Saute chopped onion and garlic in oil until soft. Add 1 cup cooked rice and 1 cup green bean casserole, stirring well to combine. Cook just until heated through. It’s an easy, tasty rice bowl topped with crispy fried onions!

Leftover Green Bean Casserole Storage Tips

To safely store leftovers for these recipes, let the casserole cool completely, then transfer to airtight, shallow containers. Refrigerate for 3-4 days. You can also freeze leftovers for 2-3 months. Thaw overnight in the fridge before using.

Follow proper food safety guidelines when reheating to 165°F and look for any signs of spoilage. With these creative ideas, you’ll never waste leftover green bean casserole again! It can be effortlessly reinvented into all sorts of delicious dishes your family will love.
