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!)

It takes about 8 minutes to throw together - less if you pick up a bag of beans trimmed green beans.

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.

Ingredients Needed For Low Carb Beans

  • Green Beans - Fresh is best here - I do not recommend canned or frozen for roasting.
  • Avocado Oil - I like avocado oil because it is netural tasting, keto-friendly, and safe at high heat. I don't recommend using extra virgin olive oil.
  • Garlic Powder - While I love minced fresh garlic, if you substitute that for garlic powder, make sure to keep an eye out so it doesn't burn.
  • Sea Salt - I used finely ground sea salt so if you are using a coarser ground, you may need to use more.
  • Black Pepper - Fresh ground is always best. Remember - quality ingredients go a long way towards making simple recipes like these keto baked green beans taste amazing.
  • Parmesan Cheese - If you are using pre-shredded, I recommend the kind that comes in the refrigerator case, not the type sold on the shelf.

How to Trim Green Beans

Growing up, we always trimmed green beans by hand - one at a time. 

These days, I like to make it easy.

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.

Picking the Best Beans

As a general rule, thinner green beans will be sweeter and crisper than those that are thicker.

When I am buying green beans that are loose in a bin, I like to snap one to make sure that they snap.

Opt for beans with a bright green color that are firm.

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 are bagged green beans, which can last a bit longer.

Roasted Green Bean Variations

  • 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.
  • To jazz things up a bit, top this with crispy fried shallots, bacon, mushrooms, or oven-roasted cherry tomatoes.
  • For an extra crunch, top with chopped almonds.

Reheating

The microwave will do the trick, but this isn't my first choice. I recommend reheating them in the oven on a parchment-lined baking sheet. Or, for the crispiest green beans, heat them in your air fryer.
