The easiest way to cook keto for a family is to make one meal with a shared base of protein and vegetables, then add a carbohydrate side, such as rice, potatoes, pasta or bread, for the people who aren’t eating keto. Tacos become lettuce wraps for you and tortillas for everyone else; spaghetti bolognese goes over zucchini noodles for you and pasta for the children. This saves time, avoids cooking two dinners, and means children still get the whole grains, fruit, beans and starchy foods they need for growth and energy. Children shouldn’t follow a ketogenic diet unless a doctor prescribes it, usually for epilepsy, so the family plan should be balanced for them first and adapted for you.
The “base plus sides” method
Plan each dinner in three parts:
- A shared protein: chicken, fish, eggs, beef, pork, lamb, tofu or halloumi.
- Shared vegetables: roasted, steamed, stir-fried or in a salad, enough to fill half of everyone’s plate.
- Separate carbs: a starchy side for those who want it, served in a separate bowl.
Sauces and toppings go on the table so everyone can choose. The NHS Eatwell Guide shows the balance children and other family members should aim for, including starchy foods and fruit.
A week of shared dinners
| Night | Shared base | Keto plate | Family extras |
|---|---|---|---|
| Monday | Spaghetti bolognese sauce | Over zucchini noodles or with a side salad | Whole wheat spaghetti |
| Tuesday | Sheet pan chicken thighs with peppers and broccoli | As is, with garlic butter | Roast potatoes |
| Wednesday | Taco night: seasoned beef or chicken, salsa, cheese, guacamole, lettuce | Lettuce wraps or a taco salad | Corn or flour tortillas, beans |
| Thursday | Salmon with green beans | As is, with lemon butter | Rice or new potatoes |
| Friday | Burgers | Bunless, in lettuce, with salad | Whole wheat buns, oven-baked fries |
| Saturday | Stir-fry with chicken or tofu and vegetables | Over cauliflower rice | Noodles or rice |
| Sunday | Roast chicken with vegetables | Cauliflower mash and gravy without flour | Roast potatoes, gravy |
Recipes that adapt well include our sheet pan chicken and potatoes, homemade burgers, sheet pan salmon with green beans and cauliflower mash.
What children need
Children and teenagers are growing, active and have high energy needs for their size. A strict ketogenic diet can be low in fiber, calcium-rich foods if dairy is limited, and some vitamins, and it can affect growth and energy. Children need:
- Starchy foods: bread, rice, pasta, potatoes, oats and cereals, ideally whole grain.
- Fruit and vegetables: at least 5 portions a day.
- Protein: including beans and lentils, eggs, fish, meat and dairy.
- Dairy or fortified alternatives for calcium. The NHS recommends at least 350 ml of milk a day, or two servings of dairy foods, for young children.
Medical ketogenic diets for children with epilepsy are carefully planned and monitored by specialist teams. Our guide to keto for children explains when they’re used. If you’re following keto, it’s best not to restrict your children’s food or comment on “good” and “bad” carbs, which can make food stressful.
Breakfasts and lunches
- Breakfast: cook eggs for everyone; add toast, fruit or porridge for the children. Greek yogurt with berries works for both, with granola added for those not on keto.
- Lunches: make a big batch of chicken, egg or tuna salad. Fill wraps or sandwiches for the family and pack it with salad or lettuce cups for you. Our healthy lunchbox ideas have more.
- Snacks: keep shared snacks such as cheese, nuts, vegetable sticks, olives and boiled eggs, plus fruit for the children.
Shopping and budget
Keto staples such as meat, fish, cheese and nuts can be expensive. To keep costs down:
- Buy cheaper cuts: chicken thighs, ground beef, pork shoulder and canned fish.
- Use eggs often. They’re one of the cheapest protein foods for everyone.
- Bulk up meals with vegetables: frozen spinach, broccoli, cauliflower and green beans are cheap and keep well.
- Cook once, eat twice: make extra for lunches.

Handling questions from children
Children notice when a parent eats differently. Keep explanations simple and positive, such as “I’m eating more vegetables and fewer potatoes because it helps me feel well.” Avoid calling foods bad or talking about weight in front of children. Eating together at the table, even if your plate looks slightly different, matters more than everyone eating exactly the same food. Our guide to family meals explains why shared mealtimes help.
Partners and other adults
If your partner isn’t on keto, the same method works. Agree on a few favorite meals that suit both of you, keep your own snacks, and avoid asking others to give up foods they enjoy. Our guide to sticking to keto when others don’t covers social situations.
Holidays and special meals
For family celebrations, focus on the dishes you can share: roast meats, vegetable sides, salads and cheese boards. Make one keto dessert, such as our keto cheesecake, alongside the usual ones. Our guide to keto at Christmas and holidays has more ideas.
Common questions
Can my children eat keto meals?
Yes, as part of a balanced diet. Keto meals built around protein and vegetables are healthy for children too, as long as they also get starchy foods, fruit and dairy through the day.
Should my whole family go keto?
No, unless there’s a medical reason. Most adults and children do well on a balanced diet, and keto isn’t suitable for growing children without medical supervision.
How do I stop cooking two dinners?
Use the base plus sides method: one protein and shared vegetables for everyone, with carbs on the side.
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).
