Onions are a key ingredient in many recipes due to their distinctive aromatic flavor. They come in different colors, including yellow, green, red, and white. They contain antioxidants that offer several health benefits. But, can you eat onion on a keto diet?

I’ll answer this question and provide you with some nutrition facts for different types of onions. Plus, help you see why onions are keto, even though many choose to eat them in moderation.

Are Onions Keto: Ketosis & Carbs

Most keto dieters aim to consume below 50 grams of carbs each day. By limiting carbs, the goal is to enter into ketosis. While keto isn’t a specific food, our food choices, can determine whether or not we can reach the ultimate goal of ketosis. With that in mind, many people eat onions on keto, but eat them in moderation. That’s because the number of onions you eat and the types of onions you choose can determine whether they are Ok for keto. I will say though, most people aren’t trying to lose weight or complaining that they gained weight because they ate way too many onions. So, while it’s important to consider if onions are keto, I’d add this to the very bottom of my list of worries. Onions add a great flavor to meals and are very easy to make using a variety of recipes. Some things to consider when eating onions on keto are:

Choose Onions With the Lowest Carbs

There are several onions types, and each type has a different number of carbs. In the next section, I’ll explain the different types and highlight how many carbs are in a cup of each type. By choosing onions with the least amount of carbs, you can enjoy them on keto without going overboard adding carbs to a dish. Onions can be used to add flavor in place of sugary condiments like dressings, BBQ sauce, ketchup, etc. Although there is sugar and carbs in onions, the content is lower than other flavored condiments.

A cup of onions in a recipe with multiple servings allows you to keep the overall carbs in a dish low, but keep a bold onion flavor. One of my biggest gripes with the ”keto police” is that they often rule out a recipe because “a cup of [random food] has too many carbs”. My immediate thoughts are always, “do what makes you happy“, but also, unless you’re planning to eat the entire recipe with multiple servings in one sitting, then you’re making a fuss about nothing.
