Easy cheesy green beans are the perfect holiday side dish! These creamy, cheesy green beans take minutes to prep and taste amazing!
Easy Cheesy Green Beans Recipe
I make Campbell's Green Bean Casserole every year for Thanksgiving. This year I decided to change it up and make two green bean side dishes.
I love the French Fried onions that normally come in green bean casserole, but I wanted to try something new. Enter in cornflakes cereal!
I love the crunch from the cereal and the cheese combination. Hello yum!
This is the perfect side dish that everyone will love! Even if you have people that don't love vegetables, they will love the creamy cheese sauce that surrounds the green beans.
Honestly, how can you go wrong with a cheesy green bean casserole that takes very little prep time.
This green bean delicious side dish also pairs perfectly with your favorite chicken and/or pork dinner. I really think we should make cheesy green beans year-round and not just around the holidays.
That being said, we are still working on a ton of holiday cookies and desserts to share over the next few weeks. We are trying to balance all of the sweet treats with a ton of vegetable side dishes.
This is a quick overview of the simple ingredients that you'll need to make Cheesy Green Beans! Specific measurements and step-by-step instructions are included in the printable recipe card at the bottom of the post.
- French Style Green Beans
- Shredded Cheddar Cheese
- All Purpose Flour

Optional - garlic, bacon, parmesan cheese

Non-stick cooking spray
1.5-quart baking dish/casserole dish
Heat resistant potholders - A couple of years ago, we had a fire scare when we didn't realize we had turned a burner on, and a cloth potholder caught fire. Thankfully we walked by the kitchen and saw the smoke, and were able to get it out ourselves. Since then, we have only used these heat-resistant potholders.
