Is Corn Keto? All You Need To Know About Corn On A Keto Diet

If you just switched over to a keto diet and are wondering, “Is corn keto friendly?”, I have some bad news: Corn contains too many carbs for it to be suitable with a keto diet. Simply eating one ear of corn can interfere with ketosis.

However, I also have some good news. Over the years, I’ve developed various ways to enjoy the flavor of corn without actually eating it.

So in this post I’ll share all my tricks to add corn-like flavors to the keto diet. I’ll also cover the carb content of corn while reviewing some of my favorite recipes, and answer some questions that you probably have.

Is Corn On The Cob OK For A Low Carb Diet?

Corn is a starchy vegetable that contains 27 grams of carbs per ear. 

This might not sound that bad since you have to limit your carbs under 50 grams daily. However, I found that most keto dieters are already eating about 30 grams of carbs per day. So even if you just eat one ear of corn, you’re risking knocking yourself out of ketosis.

Nutritional Content of Corn

One long ear (143 grams) of corn contains:

  • 27 grams of carbs
  • 4.6 grams of sugar
  • 1.7 grams of fat
  • 122 calories
  • 4.6 grams of protein

Sweet corn also has good amounts of vitamin C, potassium, magnesium and sodium. However, since you’re limiting your intake so much on keto, it’s unlikely you’ll experience significant micronutrient benefits from corn.

Can Corn Kick You Out of Ketosis?

An ear of corn has 27 grams of carbs. And because a keto diet limits your carb consumption to 50 grams a day, corn has the potential to knock you out of ketosis. 

If you’re like most keto dieters, you’re already eating around 30 grams of carbs per day. So if you eat an ear of corn, that’s 57 grams of daily carbs.

Keto Recipes With Corn

The secret to enjoying the taste of corn on keto is using corn extract. It often comes in liquid drops and tastes like corn. 

The best part is that it contains zero carbohydrates, so you can use it to flavor your meals. These are some of my favorite keto corn recipes:

  • Keto cornbread
  • Keto corn dogs
  • Keto Mexican street corn salad

These options are low-carb, so you can eat as much as you want. They also have a low GI (Glycemic Index) score – you won’t experience the sudden blood sugar spikes and crashes like with potatoes, corn syrup and other high GI foods.

Keto Cornbread

In my previous life, I was a massive fan of cornbread. So when I switched over to keto, I naturally missed it.

Luckily, a friend of mine told me about this delicious cornbread recipe, and I’ve been in love with it ever since. It only has two grams of net carbs (which is total carbs minus fiber), so you can enjoy multiple servings per day.

Keto Corn Dogs

These keto corn dogs are the perfect snack to put in your kid’s lunch box, or even take to work yourself. You only need seven ingredients and it shouldn’t take longer than 20 minutes to prepare. So gather the following ingredients:

  • Six hot dogs
  • Four cups of mozzarella cheese
  • One and a half cups almond flour
  • One egg
  • One teaspoon baking powder
  • One teaspoon xanthan gum
  • A couple drops of corn extract

Start by placing each hot dog on a skewer and setting it aside.

In a large bowl, start making your bread by melting your cheese in the microwave for one minute.

In another bowl, mix all your dry ingredients (almond flour, baking powder, salt and xanthan gum.)

Now make your corn dog dough by using an electric beater to combine your cheese, egg and corn extract with your dry ingredients. 

Roll this dough into a rectangular shape, and mold it around your hot dog on a skewer. 

Deep fry this until golden brown and dig in!

Keto Mexican Street Corn Salad

If you’re a big fan of salad or you simply want to introduce more vegetables into your diet, you’ll love this Mexican street corn salad. Start by gathering:

  • A small head of finely chopped cauliflower, plus any other veggies you feel like (this dish is very versatile!)
  • Five ounces of fresh corn
  • ¼ cup of chopped cilantro
  • ¼ cup of crumbled cotija cheese
  • A tablespoon of butter
  • Two tablespoons of garlic paste
  • Two tablespoons of mayonnaise
  • Two tablespoons of sour cream
  • A couple drops of corn extract
  • One tablespoon of minced jalapeno (you can add more for extra spice)
  • Two teaspoons of chili powder
  • The juice of one lime
  • Salt and pepper to taste

Heat up a large pan over medium high heat and melt the butter. Add your cauliflower and once it’s charred and golden brown, put it in a bowl.

Add the rest of your ingredients to your bowl after the cauliflower has cooled down, stir well, season it to taste with salt and pepper, and serve!

Keto Friendly Alternatives to Corn

The best substitutes to corn are cruciferous vegetables like broccoli, cauliflower, cucumber and kale. 



Broccoli is excellent for the keto diet because it’s low in carbs and and high in nutrients. It contains only about 4 grams of net carbs per cup and is rich in fiber, which can help promote satiety and support healthy digestion.

It’s also packed with vitamins C and K, as well as various antioxidants that have been linked to numerous health benefits, such as reducing inflammation and supporting the immune system.

This broccoli salad is perfect for summer, while you can’t go wrong with broccoli cheese soup in the colder months!

Cucumbers are great cos they are extremely low carb: A cup of sliced cucumber contains only about 4 grams of total carbs, with a negligible amount of net carbs. They are also high in water content, making them refreshing and hydrating.

Cucumbers are a good source of vitamins K and C, as well as antioxidants that may help reduce oxidative stress and promote skin health.
