Keto Red Pepper Soup

My husband is the chef in the family, so before I met him my food options were limited to easy recipes that I could prepare or take-out.

One of my favorite dishes to make at home in college was roasted red pepper soup. It tasted amazing with a bit of cheese or crushed BBQ chips!

Ok, so maybe all my add-ins weren’t the healthiest, but at it’s core, red pepper soup is pretty darn good for ya. And it’s fairly low in carbs!

We’ve tweaked that original favorite of mine to make a low carb pepper soup that is just heavenly! Plus, it’s perfect to make ahead at the beginning of the week for easy meal prepping.

Are Red Peppers Low Carb?

At first glance, 8 grams of net carbs might seem high, but if you’re doing a keto diet of 30-50 grams of carbs for the day that’s a good amount for a meal. 

It’s not realistic to think that every meal is going to be like 2 grams of carbs AND have nutrients to nourish your body. Plus, the health benefits of red peppers are so wonderful that I think it balances out the carbs, in my humble opinion.

I’m always in the camp that feeding our bodies the vitamins and minerals they need is just as important (if not more so) than any weight goal.

Here’s just a few of the health benefits of red peppers:

  • They contain a TON of vitamin C (more than 200% of your daily value)
  • Red peppers are a good source of some B vitamins
  • They provide antioxidants that fight free radicals
  • Red bell peppers support healthy eyesight

Why I Love This Recipe:

  • Lots of veggies and nutrients!
  • Only 8g net carbs for a big hearty bowl of soup
  • Perfect to make in a big batch to meal prep
