Build a balanced Christmas plate with these Christmas side Dishes and diabetes-friendly swaps. Plenty of make-ahead ideas, low-GI tips, and easy sides that everyone will enjoy.
This is exactly the kind of post I wish I’d had during our first Christmas after my daughter’s diabetes diagnosis. The holidays are a busy time and trying to balance traditional favourites with blood sugar levels all at once can be a lot.
Over the years, I’ve built a collection of healthy Christmas side dishes that make it easy to fill plates with colour, fibre and taste without sending blood sugars on a rollercoaster. These are our tried-and-true, blood sugar-friendly Christmas sides. They are full of whole foods, simple to make, plus a few clever make-ahead wins to help keep the day a little more relaxed.
If you’re still planning your festive menu, take a look at my Healthy Christmas Dinner Recipes – Easy Holiday Menu Guide for mains and full menu inspiration. And for extra support during the season, you might find my guide on Christmas and Managing Type 1 Diabetes really helpful too.
How to build a balanced Christmas plate (diabetes-friendly)
I am all about the balanced plate for managing diabetes. On Christmas Day, this simple visual takes the stress out of choosing what to serve and how much to eat.
- Aim for half the plate to be fibre (aka these delicious Christmas sides), a quarter protein, and a quarter carbs.
- Go for fibre and protein first to soften glucose rises. Think a serving of veg, then your protein, and finish with the carb sides. Plus, it’s a great way to pre-bolus for your carbs as you can still eat whilst waiting for the insulin to kick in.
- Choose lower-GI carb sides where you can. Roasted celeriac or parsnip, celeriac mash, lentil-based salads or roasted root vegetables paired with legumes.
- Keep sauces on the side and taste before adding. Many are sweeter than you expect. A homemade, lower-sugar option helps you control portions.
