Keto Spicy Peanut Cauliflower – Low Carb Recipe

Introducing keto spicy peanut cauliflower, a super simple keto side dish that is so good that you’ll wonder how you ever ate cauliflower before it! You can make it under 30 minutes and only requires a few readily available ingredients.

Spicy Peanut Sauce

Cauliflower is the main part of this dish and as you may well know it is very low in carbs (3g per 100g) making it perfect for keto! However, eating it plain can be a bit dull. Enter, spicy peanut sauce, this livens up the side dish and will leave you wanting seconds.

The sauce itself is made up of 6 core ingredients and all of them can be found in UK supermarkets. Although, you do need to be careful which brands you buy, as some will contain added sugar and will not be keto-friendly.

To make life easier, here are some product recommendations for the best keto-friendly ingredients:

Peanut butter – check out our guide on the best low carb peanut butter for the lowest carb nut butter. If you prefer, you can also use any nut butter, like almond.

Sriracha – many contain a lot of sugar, check out our low carb sauces guide for the lowest carb sriracha sauces.

Soy sauce – the carb count can vary greatly amongst brands, check out our guide on the lowest-carb soy sauces for some recommendations.

Lime juice – you can either use the juice of a whole fresh lime or 2-3 tbsp of lime juice which can be found in most UK supermarket baking aisles.

Sesame oil – almost any brand will do as it doesn’t contain any carbs.

Olive oil – similarly to sesame, any brand will do, just make sure it’s not a blend of oils.

Add a bit of sweetness

This is entirely optional but if you want to add a bit of sweetness to compliment the spice then why not add some sweetener? I occasionally add a couple of drops of liquid sucralose to the sauce, I find that it really enhances the flavour.

If you don’t have sucralose to hand then most other keto-friendly sweeteners are fine. Check out our list of recommended low carb sweeteners here.

Making a meal out of it

To be honest, I sometimes like to have a double serving of keto spicy peanut cauliflower by itself as my dinner. However, if I’m making this as just a side dish, then I like to pair it with some Chinese style roasted chicken thighs. The two go perfectly together and is one of my favourite low-carb dinners!
