Carbs in Roasted Red Peppers

Bell peppers are low in carbs but they vary between colours with green bell peppers being the lowest in carbs and yellow the highest. A red pepper is under 5.3g net carbs per cup.

Red peppers are high in vitamin C, A and E. They are delicious raw with a slight sweet taste.

How to make keto red pepper soup

This soup is so easy to make. The red peppers, onion and garlic are roasted for a richer flavour. Then added to the other ingredients and blended. Easy!

The red peppers can also be grilled until charred and their skins removed.

What to serve with keto red pepper soup

Enjoy the classic flavour combination of a tomato soup and grilled cheese but keep it low carb with our keto grilled cheese recipe.

Serve this soup as an appetizer or enjoy it for a light lunch or supper. A side of low carb bread rolls or even a few slices of our low carb garlic bread make this a filling meal too.

Can you freeze this soup?

This red pepper soup freezes very well as there is no dairy in it. Too freeze, allow the soup to completely cool. Then pour into a zip lock bag or air tight container. This soup should freeze for up to 3 months.

Recipe Tips

To skip the roasting and for a quicker soup, use a jar of roasted red peppers. Saute the onion and garlic, then add the other ingredients as per the recipe card,

Replace the red chili with fresh basil for a fresh flavour.

Add heavy cream to the blended soup for a creamier soup.
