If you’re looking for an appetizer or side dish with a fresh twist on a beloved Thanksgiving classic, this recipe is for you! These mini casseroles are perfect for snacking and bring all those cozy, nostalgic flavors into a fun bite-sized treat.
Grease a muffin pan or use a silicone muffin pan or muffin baking cups
Open and drain the green beans and put them in a large bowl
Add the cream of mushroom soup, the shredded cheese, the French-fried onions and the salt and pepper. Stir to combine and set aside
Cut the puff pastry sheet into 12 equal squares and place a square in each muffin cup.
Using an ice cream scoop or a large spoon, fill the muffin cups with the green bean mixture almost to the top.
Add a little extra shredded cheese and crispy fried onions to the top of each cup.
Bake the mini green bean casseroles for approximately 25 minutes or until bubbly and the tops are turning golden brown.
Notes
Don’t Overfill. These are not like eggs that rise a lot when cooking, so you can fill them close to the top. Fill the cups almost full, but leave about 1/2 to 1/4 inch to add the extra cheese and fried onion topping. You want to fill the cup, but you don't want the mixture to bubble over.
Let the Casseroles Cool Before Removing. Letting the casseroles cool for about 10 minutes helps them set so you can pop them out without falling apart.
