Staying keto at Christmas and other holidays is easier than it sounds, because many festive foods are naturally low in carbs: roast turkey, chicken, beef or fish, Brussels sprouts, green beans, cauliflower, red cabbage, cheese boards, nuts and olives. The carbs hide in roast potatoes, stuffing, bread sauce, gravy thickened with flour, cranberry sauce, Christmas pudding, mince pies, sweets and drinks. Plan a few keto swaps, bring a dish you can eat, go easy on alcohol, and decide in advance whether you’ll stay strictly keto or relax for a day or two. Either way, enjoying the occasion and the company matters more than perfection.
What to eat at a keto Christmas dinner
| Keto-friendly | Watch out for | Easy swap |
|---|---|---|
| Roast turkey, chicken, beef, lamb, salmon | Glazed ham with honey or sugar | Ham with a mustard and herb crust |
| Brussels sprouts, green beans, broccoli, red cabbage (without sugar) | Roast potatoes, parsnips and carrots in large amounts | Roasted cauliflower or celeriac |
| Gravy made from pan juices | Gravy thickened with flour or granules | Reduce the juices or thicken with a little xanthan gum |
| Pigs in blankets (in moderation) | Stuffing made with bread | Nut, mushroom and herb stuffing |
| Cheese board with celery and cucumber | Crackers and chutneys | Keto crackers or vegetable sticks |
| Berries with cream | Christmas pudding, mince pies, trifle | A small keto cheesecake or berries and cream |
Tips for the big day
- Eat a normal breakfast, such as eggs and smoked salmon, so you don’t arrive at dinner starving.
- Fill your plate with turkey and vegetables first, then add small amounts of sauces.
- Offer to bring a dish you know you can eat, such as cauliflower cheese or a keto dessert.
- Choose your treats. If there’s one festive food you love, decide whether to have a small portion and enjoy it.
- Keep moving: a family walk after lunch helps digestion and is a nice tradition.
- Drink water between other drinks.
For the main event, our guide on how to roast a turkey covers timings and food safety.
Keto-friendly side dishes
- Roasted Brussels sprouts with bacon or chestnuts, using only a few chestnuts, as they’re higher in carbs.
- Cauliflower cheese, made with a cheese sauce thickened with cream cheese rather than flour.
- Creamy cauliflower mash. Our keto cauliflower mash stands in for mashed potato.
- Garlic green beans with toasted almonds. Our green beans with toasted almonds is a crowd-pleaser.
- Braised red cabbage made with vinegar, spices and a little sweetener instead of sugar.
- Roasted celeriac cubes with thyme, as a lower-carb alternative to roast potatoes.
Keto desserts and treats
- Keto cheesecake with berries. Our keto cheesecake uses an almond base.
- Chocolate nut clusters. Our keto chocolate nut clusters make good gifts.
- Berries with whipped cream and a little orange zest.
- Spiced nuts: almonds and pecans roasted with cinnamon, nutmeg and a pinch of salt.
- A small piece of very dark chocolate with coffee.

Drinks at Christmas
Many festive drinks are high in sugar: mulled wine, eggnog, liqueurs, cider, beer, cocktails and sweet sparkling wine. Lower-carb choices include dry wine, brut sparkling wine and spirits with a sugar-free mixer, but alcohol is still worth limiting. The NHS advises not regularly drinking more than 14 units a week, spread over 3 or more days. On keto, alcohol can affect you more quickly, and your body uses it before fat, which can slow progress. Our guide to keto and alcohol covers the lowest-carb options, and our mocktail recipes are a festive alcohol-free choice.
Food safety for festive leftovers
Large family meals produce a lot of leftovers. Cool them quickly and refrigerate within 2 hours, and eat within 3 to 4 days, as the USDA advises. Leftover turkey makes excellent keto salads, soups and omelets for the days after Christmas.
Should you take a break from keto?
Some people choose to eat normally for a day or two over the holidays and return to keto afterward. That’s a personal choice. If you do, expect your weight to go up a little from extra water and glycogen, and you may feel some keto flu symptoms for a few days as you return. If you have diabetes or another medical reason for following keto, talk to your doctor before changing your diet, as medicines may need adjusting. Our guide to how long it takes to get into ketosis explains what to expect.
Other holidays and celebrations
The same principles work for Thanksgiving, Easter, Diwali, Eid, birthdays and weddings: focus on the protein and vegetables, choose sauces and sides carefully, bring a dish you can eat, and decide in advance how you’ll handle desserts and drinks.
A keto-friendly Christmas menu
- Breakfast: scrambled eggs with smoked salmon and chives.
- Nibbles: olives, cheese cubes, cucumber with cream cheese, and spiced nuts.
- Main: roast turkey with pan-juice gravy, roasted Brussels sprouts, cauliflower cheese, green beans and braised red cabbage.
- Dessert: a slice of keto cheesecake or berries with whipped cream.
- Evening: a cheese board with celery and keto crackers, and herbal tea.
Preparing a few dishes in advance, such as the cheesecake, the spiced nuts and the red cabbage, makes the day less stressful.
Common questions
Can I have a glass of wine on Christmas Day?
A glass of dry wine contains few carbs, so it can fit, but alcohol adds calories and can lower your willpower around food. Keep it to one or two glasses and drink water in between.
Is turkey keto?
Yes. Plain roast turkey has no carbohydrate and is a lean, high-protein choice.
Are Brussels sprouts keto?
Yes, in normal portions. They’re a low-carb, high-fiber vegetable.
How do I deal with family pressure to eat?
Keep it simple and positive. Saying “I’m full, but it was delicious” works well. You don’t need to explain your diet in detail.
Safety note: Keto isn’t suitable for everyone. If you have diabetes, kidney or liver disease, take regular medication, or are pregnant or breastfeeding, talk to your doctor before cutting carbs this far (why it matters).
This article is general information, not medical advice. Talk to your doctor or a registered dietitian before making big changes to how you eat, especially if you have a health condition, take regular medication, or are pregnant or breastfeeding.
