Is Soup Good on a Keto Diet?

Unfortunately, most shop-bought soups are high in sugar.

This is due to them needing to be preserved on the shelves and in order to give them a flavour that can be stored.

Your best option is to create your own simple masterpieces and freeze them so you have a lovely home-cooked, keto-friendly soup, whenever you want it!   

What kind of Soup can I eat on Keto?

All kinds!

Most soups that you have eaten on a non-keto diet can be adapted to be enjoyed on a keto way of eating. You may have to reduce the number of onions that are used as the base of most soups and replace high carb vegetables with low carb vegetables.

For example, a potato-based soup can soon be adapted to be made with celeriac and double cream. The carbs in onions can be reduced by using leaks and so on. A lot of Mediterranean soups will focus more on aubergine and courgettes as their base which can also be a perfect option for keto.

Is Cheese & Broccoli soup good for you? ??

Like I said above, broccoli, ok. Cheese, good. Broccoli & cheese soup, amazing!

I like broccoli, even as a child I ate it no problem. As an adult, I eat it without complaint. It’s not the most flavoursome veg, but I don’t find it offensive either. However, combine broccoli and cheese and you have a Broadway success. Wicked, eat your heart out!

This soup is low in carbs and high in fat. As with all food like this, it is filling and satisfying, meaning that you won’t be snacking after eating! On keto, I use a lot of grated cheese in recipes, although grating cheese is my most loathed kitchen task.

You have to be careful using shop-bought grated cheese as often ingredients are added in order to keep the grated cheese from clumping. These ingredients are not often keto-friendly and will add to your carb count. Where you can, try and avoid them, or at least check the carb count first.

How many carbs are in Cheese & Broccoli Soup?

This particular keto version has 5 grams of carbs, if you’re particularly hungry you can always up your cheese portion. Or if you’re wanting soup as a starter you can reduce your portion so as to not go over your carb allowance. I have tried this with leftover shredded chicken from a Sunday roast – it’s perfect to use up the leftover broccoli too!

How do you make Cheese & Broccoli Soup from scratch?

It really is simple! I sauté all of my ingredients in a heavy-based pan and then I blend all of the ingredients in a NutriBullet to ensure that it is smooth. All of the ingredients are placed back into the pan and then heated through with the cream. It’s the cream that makes that brings this whole recipe together.

Adding the xanthan gum will thicken the soup, don’t be tempted to add any more than is in the recipe or it will become too thick. The xanthum gum is a keto-ers best friend. Where potato or other starchy option would be used to thicken a sauce or soup xanthan gum can be used in it’s place.

As for the seasoning I like this quite peppery so add a good amount at the end, but the seasoning is up to you!

What goes well with this yummy Cheese & Broccoli Soup?

All of the options that you would have eaten with soup on a non-keto diet you can eat with this. For example;

  • Keto Bread
    • Keto Rolls
    • Keto Edam Crackers
    • Keto Chia Crackers
    • Keto Croutons
    • Pork Scratchings (personally I prefer salt or salt and pepper seasoned)
