Low carb dinners: 16 under 20 g of carbohydrate

What is a low carb dinner?

In practice, one under about 20 g of carbohydrate, which means no substantial portion of rice, pasta, potato or bread. Protein plus vegetables cooked in a decent amount of fat reaches that easily without feeling restrictive.

The part people get wrong is compensation. Removing 60 g of carbohydrate takes roughly 240 calories off the plate, and if nothing replaces it the meal does not satisfy. Fat and protein are what fill the gap.

The substitutions that work

Three are genuinely good, 2 are acceptable, and 3 are not worth attempting. Being honest about which is which saves a lot of disappointing dinners.

Six more between 10 g and 20 g

These use a substitution or a small quantity of a starchy vegetable, which buys variety without moving far up the scale.

• Chicken curry with cauliflower rice. About 16 g. Fry the cauliflower dry first, then serve the curry over it rather than mixing them.
• Sausages with celeriac mash. Around 18 g, the highest here. Roast the celeriac before mashing it with butter, or it stays watery.
• Egg and halloumi traybake. About 12 g, with peppers and courgette doing the volume.
• Prawn and pak choi stir-fry. Roughly 12 g, using tamari and sesame rather than a sweet sauce.
• Salmon with courgette ribbons. About 10 g, and the ribbons need salting and squeezing first.
• Aubergine lasagne. Around 14 g, with roasted aubergine slices in place of pasta sheets.

The aubergine lasagne is the one worth the effort for a weekend, because it is the only substitution here that produces something genuinely comparable to the original rather than merely acceptable in its place.

Five dinners under 10 g

These are the lowest here and none of them relies on a substitution at all, which is why they are the easiest place to start.

• Steak with mushrooms and butter. About 6 g. Mushrooms fried hard and undisturbed until browned, then butter and garlic for a minute.
• Chicken thighs with greens. Around 8 g and 40 g of protein. Thighs roasted skin up at 200C, greens wilted in the fat afterwards.
• Baked cod with aioli. About 8 g. The aioli supplies the fat that makes it satisfying.
• Frittata with feta and spinach. Roughly 8 g, and just as good cold the next day.
• Beef mince lettuce cups. About 10 g, with the mince seasoned heavily enough to carry the whole dish, since there is no starch on the plate to soak up a mild sauce.

Four mistakes that make it unsustainable

Low carb eating tends to fail for the same handful of reasons, and none of them is about willpower.

• Cutting fat at the same time. Removing both leaves a plate that cannot satisfy anybody.
• Boiling the substitutes. Watery cauliflower rice and courgette is the fastest route to giving up on the whole idea.
• Trying to replace bread and pizza. Substitute doughs disappoint. Choose dishes that never needed them.
• Forgetting fibre. Non-starchy vegetables, nuts and seeds keep the meal working, and their absence is felt within a few days.

Avoid those 4 and the pattern is comfortable. Fall into them and it feels like deprivation, which is the usual reason people abandon it in the second week.

How do you stay full without the base?

Add fat deliberately and keep protein high. Those 2 together do the job the rice was doing, and skipping them is why low carb dinners get a reputation for leaving people hungry.

1. 1Aim for 35 g of protein or more. It is the most satiating macronutrient, and it matters more here than in any other kind of cooking.
2. 2Cook in butter or olive oil rather than minimising fat. Removing carbohydrate and fat at the same time leaves very little on the plate.
3. 3Add a fat-based sauce. Aioli, herb butter, tahini or a yoghurt dressing changes how substantial a plate feels.
4. 4Double the vegetables. Volume does part of the work, and non-starchy vegetables add very little carbohydrate.
5. 5Include something with fibre. Non-starchy vegetables, nuts and seeds keep the meal working for longer.

If you are tracking rather than estimating, track macros in recipes explains how to get numbers from your own cooking, and substitute ingredients covers swaps more generally. For a different restriction handled the same way, gluten-free dinners works from naturally compliant dishes rather than substitutes.
