Eating Keto at a French Bistro

The ketogenic diet doesn’t mean avoiding restaurants entirely. French bistros, with their emphasis on protein and vegetables, can be surprisingly keto-friendly if you know what to look for. The key lies in recognising hidden carbohydrates in sauces and sides while embracing the dishes that align with low-carb principles.

Classic French dishes that work

Start with steak tartare – high-quality minced beef with egg yolk, capers, and herbs contains virtually no carbs. Escargots in garlic butter (£8-12 at most London bistros) are another safe choice, though avoid the bread served alongside. For mains, entrecôte with béarnaise sauce (ask for no potatoes) or duck confit with green beans make balanced keto meals.

keto-friendly sauce options like hollandaise or beurre blanc typically contain less than 2g carbs per serving, while cream-based sauces often have added flour. Always verify ingredients with staff – many French chefs will accommodate requests to omit thickeners.

What to watch out for

Traditional French cooking relies on techniques that can derail ketosis. Onion soup, though delicious, contains caramelised onions and often bread. Coq au vin uses wine and sometimes flour for thickening. Even ratatouille can be higher in carbs than expected due to the natural sugars in cooked vegetables.

Desserts pose obvious challenges, but many bistros now offer cheese plates (£6-9 at chains like Côte). Select hard cheeses like Comté or Brie over softer varieties, which may contain more lactose. A small portion of berries with crème fraîche makes a suitable alternative if available.

What this means in practice

A typical keto-friendly French bistro meal might include:

• Starter: Salad Niçoise without potatoes (£7.50 at Pret’s French outlets)
• Main: Grilled salmon with spinach and lemon butter (£16-22)
• Side: Steamed asparagus with hollandaise (£4 at Waitrose café)
• Drink: Sparkling water with lemon

navigating keto at Indian restaurants requires different strategies, but the principle remains: focus on protein and non-starchy vegetables while avoiding breaded items and sugary sauces. In French cuisine, this means embracing the butter and cream while steering clear of flour-thickened bases.

Frequently asked questions

Can I eat French onion soup on keto?

Traditional versions contain too many carbs from onions and bread. Some restaurants offer low-carb adaptations, but these are rare. Better to start with a green salad with vinaigrette.

Are croissants completely off limits?

A standard croissant contains about 25g carbs – nearly a full day’s allowance on strict keto. Some bakeries now offer almond flour versions, but these aren’t common in traditional bistros.

What about wine?

Dry reds like Cabernet Sauvignon (3-4g carbs per glass) are preferable to sweeter whites. Champagne and brut sparkling wines also work in moderation.

The bottom line

French bistros offer numerous keto-compatible options if you focus on unprocessed proteins, leafy greens, and sauces without thickeners. The challenge lies in resisting bread baskets and starchy sides. If you’d rather not do the macro maths yourself, the Keto Dieting app does it for you on Google Play and the App Store.
