The strawberry season is in full spin and I've been working on a ton of new recipes featuring berries so you'll have plenty to try.

A few days ago I shared this Keto Fluffy Strawberry Cream — have you tried it? It's the most viral recipe I shared this month and for a very good reason. This keto dessert is so easy, quick and oh so fluffy. It's divine!

This simple Low-Carb Strawberry Syrup is adapted from a recipe I originally created for my Beginner's KetoDiet Cookbook back in 2017. I used this homemade sugar-free syrup to make a keto-approved Strawberry Cream Soda recipe which was a hit!

How To Make Sugar-Free Strawberry Syrup

Making strawberry syrup with no sugar is easy. You need strawberries — fresh pr frozen, water and granulated low-carb sweetener.

I used allulose as it doesn't crystallise once refrigerated but you can use other options including Erythritol, Swerve or granulated sweetener mix that uses stevia or monk fruit. I don't like my syrup too sweet so I used just half cup. Feel free to add more sweetener, up to about a cup.

I found that strawberries work best as they make the syrup nice and thick. Any other berries will work so you can try this with raspberries, blueberries or blackberries.

How To Use Strawberry Syrup

This low-carb strawberry syrup is perfect for making quick sugar-free beverages and summer low-carb cocktails. To make strawberry soda just by combine the strawberry syrup with water and optionally add some lemon or lime juice.

You can also use it to make strawberry cream coda just by adding a dash of whipping cream of coconut cream, or drizzle over some ice cream such as my Smooth & Creamy Vanilla Keto Ice Cream, low-carb pancakes or chaffles!

I changed the way I ate in 2011, when I was diagnosed with Hashimoto’s, an autoimmune disease that affects the thyroid. I had no energy, and I found it more and more difficult to maintain a healthy weight.

That’s when I decided to quit sugar, grains, and processed foods, and to start following a whole-foods-based ketogenic approach to food.
