Belgian chocolate has a genuine claim to being the best in the world, which makes it either a comfort or a problem depending on what you’re trying to eat. The honest answer is: some of it is fine on keto, most of it isn’t, and the distinction is simple enough.
Dark chocolate at 70% cacao or higher has a small enough amount of sugar that moderate consumption — a few squares, not a bar — fits within a sensible keto day. Belgian dark chocolate at that percentage is excellent. The problem is that Belgium’s most famous chocolate tradition is pralines, ganaches, and milk chocolate — the beautifully packaged boxes on the Sablon, the shops that tourists queue outside on the Grand-Place. All of that is high sugar and not relevant to your current project.
What’s actually fine
Côte d’Or is the Belgian mass-market chocolate brand and their 70% and 86% dark bars are good, widely available, and reasonably priced. You’ll find them at any supermarket. The 86% is slightly bitter and very good. The 70% is more approachable. Either works.
Galler is a step up in quality from Côte d’Or and makes a noir 70%, noir 85%, and noir 90% that are all worth trying. Their bars are available at Delhaize, some petrol stations, and their own shops. The packaging is distinctive — long thin bars in coloured wrappers — and the chocolate is genuinely good.
Neuhaus is primarily known for pralines but also makes a noir intense line. More expensive than Côte d’Or or Galler, available at their shops and some supermarkets.
Lindt isn’t Belgian but it’s everywhere in Belgium and the 85% and 90% are reliable if you can’t find the local alternatives.
The craft chocolate scene
Brussels has developed a small but real bean-to-bar scene over the last decade. A few shops worth knowing:
Laurent Gerbaud near the Grand-Place focuses on dark chocolate with inclusions — nuts, dried fruits in small amounts, spices. His plain dark tablets are good and the shop is worth visiting. Some of the nut-based bars are keto-friendly; the ones with dried fruit need a label check.
Pierre Marcolini on the Sablon is probably Brussels’ most acclaimed chocolatier. Beautiful work, very expensive, primarily pralines and ganaches which aren’t keto-friendly. However he also makes single-origin dark tablets that are excellent if you want to spend the money. Treat it as an occasional indulgence rather than a snacking staple.
What to avoid
Milk chocolate regardless of brand. Pralines — the filled chocolates that are Belgium’s main gift item — are typically ganache or cream-filled with significant sugar. White chocolate. Anything with the word “praliné” on it. The hot chocolate at the market stalls, which is thick, sweet, and nothing like drinking plain melted dark chocolate.
The chocolate shops on the Rue au Beurre and around the Grand-Place are primarily selling milk chocolate pralines in beautiful boxes to tourists. They look extraordinary and they’re not for you.
Practical notes
Supermarkets: Delhaize, Colruyt, and Carrefour all stock Côte d’Or and Galler dark chocolate. This is your everyday option and it’s genuinely good.
Portion size matters. A few squares of 85% dark chocolate after dinner is a legitimate keto-friendly habit. Half a bar in one sitting is a different thing. The high cacao percentage makes it filling quickly, which helps.
Belgian dark chocolate at 85% with a small glass of oude jenever is one of the better combinations available to someone doing keto in this country. It doesn’t compensate for the waffles, but it’s something.
