All the flavors of classic green bean casserole served in mini filo shells. These make a great Thanksgiving appetizer or side dish.

Green Bean Casserole Cups

I have a confession to make. I’ve never been a fan of the green bean casserole that’s so popular at Thanksgiving.

But I’ve always wanted to like it, so I’ve spent some time experimenting with variations on the green bean casserole theme and came up with something that I really love–Green Bean Casserole Cups.

These tasty little morsels have all of the flavors of the classic casserole, including a creamy homemade sauce, served up in a tasty, bite-sized filo shell.

And of course, they’re topped off with some crispy French fried onions! Those are a must in my book. I don’t know about you, but I eat French fried onions straight from the container.

I really and truly dislike the usual green bean casserole, but I couldn’t stop eating these tasty little bites.

The number one reason this version of green bean casserole is so good is that the recipe uses fresh or frozen vegetables, rather than canned. Trust me, it’s worth the few extra minutes it takes to chop up some green beans and mushrooms!

But with the help of pre-made filo dough, and store-bought French fried onions, these savory morsels are super quick and easy to make.

I mean, if you wanted to go all out, you could also make your own filo dough and crispy fried onions, but that’s pretty time consuming, and I do like to take shortcuts where I can when it comes to holiday dinner prep.

If you feel like I do about this traditional Thanksgiving side dish, give this version a try! There may just be a green bean casserole lover in you too!

Whether you serve these as an appetizer or a twist on the popular side dish, these Green Bean Casserole Cups are sure to be a hit at your Thanksgiving dinner.

    You claim to have come up with this green bean casserole in little cups but I saw it on the Campbell soup website under variations for Green Bean casserole. Did they get it from you? They did not mention you.

  • Sharon Schroeter

    This sounds great! Are the green beans cooked more than the 4-6 minutes in the oven?
    Thanks,
    Sharon

        Sorry Danielle–guess I need to learn to read 😉

  • How would I make this without the mushrooms?

    • I'd just use cream of chicken.

      From one Lindsey to the next

    • I recommend making the green bean mixture the traditional way (like on the back of the fried onions container) EXCEPT substitute cream of chicken for the cream of mushroom. It’s still good- we have been making it this way for our mushroom haters in the family! Hope this helps 🙂
