Hello there, health-conscious friends! I've been asked a question so many times that it's high time I gave a definitive answer. So, are onions keto? You're about to find out! We'll discuss everything from the yellow onions you might use in a hearty French onion soup to the green onions that are a staple in Mexican cuisine. So, whether you're a long-time keto dieter or just beginning your journey, let's take a closer look.
Are onions keto?
The ketogenic diet, also known as a low-carb diet, has been gaining in popularity due to its potential health benefits, such as weight loss, reduced blood sugar levels, and potential protection against heart disease. One of the key factors to achieving the state of ketosis is the restriction of carbohydrates, but that doesn't mean you have to give up all your favorite recipes!
Let's start with the most common onions - yellow onions, red onions, white onions, and green onions - and find out their carb count.
The Nutritional Facts of Different Types of Onions
As you can see, all types of onions have a similar amount of carbohydrates. The only exception is shallots, which have slightly fewer carbohydrates than other types of onions.
If you are on a low-carb diet, you may want to choose shallots over other types of onions. However, all types of onions are still a good source of fiber and nutrients.
The most common variety in many kitchens, yellow onions, have a strong flavor that mellows and sweetens as it cooks. A medium onion (about one cup chopped) contains about 15 grams of carbohydrates. After subtracting the 3 grams of fiber, the net carbs amount to 12 grams.
With a slightly higher sugar content, red onions are best used in moderation. A medium red onion contains approximately 16 grams of total carbs and 2 grams of fiber, resulting in 14 g net carbs.
White onions, frequently used in Mexican cuisine for their sweet flavor, pack about 16 grams of carbs in a medium onion, with 3 grams of fiber, which equals to 13 g net carbs.
Green Onions (Spring Onions)
The best type of onions for keto dieters may be green onions. One medium green onion contains about 1.3 grams of net carbs, making it a great option for a low-carb diet.
Sweet onions, like Vidalia and Spanish onions, have a higher sugar content. With 15 grams of carbohydrates in a medium onion and 3 grams of fiber, the net carbs count comes to 12 grams.

Tips for Including Onions in Your Keto Diet
While raw onions might pack more carbs than other non-leafy vegetables, the good news is that a little goes a long way. Here are some tips for adding onions to your keto dishes:
- Moderation is Key: You don't need an entire onion to get the flavor you crave. A serving size of one-half cup of chopped onion can easily spread throughout an entire keto meal.
- Choose the Right Type of Onion: Opt for green onions or regular onions over sweet varieties to lower your carb intake.
- Use Onion Powder: A sprinkle of onion powder can provide a similar taste with fewer carbs. Be sure to check the label as some brands may have added sugars.
- Cook with Healthy Fats: Sauté your onions in healthy fats like olive oil or avocado oil. You can also make caramelized onions using a sugar substitute and a healthy fat for a delicious keto-friendly topping.
Keto Onion Recipes
When done right, onions can be a great addition to your keto meal plan. One of my favorite keto recipes is Keto Onion Rings. By using almond flour, pork rinds, and your preferred type of onion, you can create a dish that's surprisingly low in carbs but high in flavor!
keto onion rings:
- 1 large onion, sliced into 1/2-inch thick rings
- 1/2 cup almond flour
- 1/4 cup grated Parmesan cheese
- 1/4 teaspoon salt
- 1/8 teaspoon black pepper
- 1 egg, beaten
- 1 tablespoon water
- 1 tablespoon olive oil
- Preheat oven to 400 degrees F (200 degrees C).
- In a shallow bowl, combine almond flour, Parmesan cheese, salt, and pepper.
- In a separate shallow bowl, whisk together egg and water.
- Dip each onion ring in egg mixture, then in almond flour mixture.
- Place coated onion rings on a baking sheet lined with parchment paper.
- Drizzle with olive oil.
- Bake for 15-20 minutes, or until golden brown.
- Serve immediately with your favorite dipping sauce.
Here are some tips for making keto onion rings:
- Use a good quality almond flour. This will help to create a crispy coating.
- Don't overcrowd the baking sheet. This will prevent the onion rings from cooking evenly.
- Don't overbake the onion rings. They should be golden brown, but not burnt.
- Serve immediately with your favorite dipping sauce.
Here are some variations on the recipe:
- You can use different types of cheese in the coating, such as cheddar, mozzarella, or Gruyère.
- You can add herbs and spices to the coating, such as garlic powder, onion powder, or paprika.
- You can serve the onion rings with different dipping sauces, such as ranch dressing, blue cheese dressing, or ketchup.
As you can see, these keto onion rings are a relatively low-carb snack or meal option. They are also a good source of protein and fat, which can help you feel full and satisfied.
Here are some tips for making these keto onion rings even healthier:
- Use a healthier oil, such as avocado oil or olive oil.
- Use a lower-fat Parmesan cheese.
- Add herbs and spices to the coating, such as garlic powder, onion powder, or paprika.
- Serve the onion rings with a healthy dipping sauce, such as ranch dressing made with Greek yogurt or blue cheese dressing made with avocado oil.
