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 - Use the best quality you can afford. 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.

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. (Obviously with what is going on in the world right now, I am currently buying them in a package.)

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

Storing Green Beans

Green beans don't last long at all in the refrigerator.

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, and Asiago are all good options.
To jazz things up a bit, top this with crispy fried shallots or oven-roasted cherry tomatoes.
For an extra crunch, top with chopped almonds.

Frequently Asked Questions

Are Green Beans Keto-Friendly? How Many Net Carbs Do They Have?

Are green beans low carb?

They sure are and are perfect for the keto diet!

A one-cup serving has 7 grams of carbohydrates and 3.4 grams of fiber for a total of 3.6 grams of net carbs.

If you are going to eat beans on a ketogenic diet, green is the way to go.

Are cooked green beans good for you?

Absolutely! Not only are they packed with fiber, but they are also a great source of vitamins A, C, and K. A one cup (100 grams) serving has 3.6 net carbs.

What type of green beans are best for this recipe?

While I have nothing against canned or frozen, this is one case where fresh is best! Canned just aren't meant for roasting - they are best made in a skillet.

If frozen is your only option, you can give it a try, but you can expect a bit of sacrifice when it comes to texture.

Can you reheat roasted green beans?

Yes! 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.

What goes with roasted 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. Really, they go with almost any protein!
