Roasted Green Beans with Parmesan are a satisfying and fun side that even the kids love! With just a handful of ingredients and requiring only a few minutes of hands-on time, this Keto Green Bean Recipe is perfect when you need an easy side without a lot of fuss. It works just as well for the holidays as it does a weeknight dinner.

If you are looking for the perfect keto side dish, you are going to fall in love with these Keto Green Beans.
Aside from oil, salt, and pepper, there are just three ingredients making this a roasted veggie side that is PERFECT for busy weeknights. (But delicious enough for special occasions like Thanksgiving, Christmas, Easter, and Mother's Day!)
I love to serve green beans with a good marinated steak. Other great options include Chicken Fried Steak, Chicken Cordon Bleu, or a simple Air Fryer Chicken.
Ingredient Notes
- Start with fresh green beans. They roast much better than canned or frozen.
- Garlic powder keeps things simple and won’t burn as easily as fresh garlic when roasting.
- If you’re buying pre-shredded parmesan, grab the kind from the refrigerated section rather than the shelf-stable one. It melts and tastes much better.
- Green beans and parmesan cheese are a match made in heaven, but other cheeses will work here too. Goat cheese, feta, blue cheese, cheddar, and Asiago are all good options.
How to Trim Green Beans
The easiest way to trim beans is to line them up on a cutting board so that the stems are even. Cut the stems with a sharp knife. Or, make your keto diet just a little easier by buying them pre-trimmed.
Storing Green Beans
Green beans don't last long in the refrigerator at all.
I recommend buying them just a day or two before storing and keeping them in paper towels in an open produce bag. The exception to this is bagged green beans, which can last a bit longer.
