This low-carb Bacon and Cheese Vegetable Gratin has brunch time sorted.

Weekends are the time I look forward to a lazy brunch. After a busy week there’s nothing better than a comforting breakfast with the family. When I served this I literally giggled with all the lip smacking ‘wows’ that came from round the table. I mean who doesn’t love cheese and bacon? But with so much veg packed into one tiny tray it’s super filling and yet low carb.

Keeps well in the fridge too so you can reheat the leftovers for dinner. Let me know what you think of this one in the comments below. I love it.

This one is a winner! Trying to regain control of my weight and health after years of neglect is extra tough when Hubby isn’t on the same page...but even he loves this. Super yummy and makes my heart smile knowing there is no guilt and my body is being truly nourished. Easy to tweak to make lots of different versions. Planning ahead and adding chicken makes a great all in one meal on busy evenings. Thank you for helping a struggling chubby girl! 😁

Thank you Kristie!

how many ounces is a serving

Hi Ruth, that's hard to tell - we didn't weigh it after baking it and there is always some water loss during the baking process. It should be easy to divide into individual servings if you use a baking tray, or you can use individual single-serving ramekins.

Absolutely loved this recipe, so did my husband. Will be making it again very soon! Thank you 😊

Is „courgettes“ and “celeriac” GB english?

It is 😊 Courgette = zucchini. Thanks for spotting it, I'll clarify that. I think that celeriac should be both American and British expressions (at least I think they are) - it is the same as celery root. Then there is celery which refers to celery stalk (the green and very low-carb part of the vegetable).

This looks really tasty!
