I love green beans, especially around the holidays. No Thanksgiving dinner is complete with them. This is an easy keto thanksgiving side dish that you can make for your holiday dinner or bring to a potluck. They are also perfect paired with a simple weeknight dinner, like 
Although traditional maple syrup is not keto friendly, there are low carb versions available that are. 
Green beans have a higher carb count that other green vegetables. If you eat them in moderation, they are still keto friendly. One cup of cooked green beans contains 10 grams of total carb and 6 net carbs.
We don’t eat them too often but around the holidays, it is necessary. I can’t have turkey without a side of green beans. Plus there are other nutritional benefits to green beans. They have lots of vitamin C and silicon (good for bone, skin and hair).
To trim greens beans you can line up the stem side of the green bean and slice off the stems. You can also snap off the stem side one by one. The other end, you don’t need to remove. This side is tender and perfectly fine to eat.
Most mustard is keto approved; although, it is important to read the nutrition label to make sure there are no sugars added. I like to use two different mustard in this recipe. The stone ground mustard provides flavor and I like the appearance of the ground mustard on the green beans. If you don’t have access to stone ground mustard, you can double the amount of Dijon mustard in this keto green bean recipe.
I made this for a family dinner and everyone raved about the flavor blend. The combination of mustard and maple gave it such a nice balance. I especially loved how the beans stayed perfectly crisp after roasting.
thank you. a perfect keto side dish!
