Brief your riad at check-in. Riads prepare breakfast fresh each morning and most will adapt on request — no amlou on the table, gluten-free options sourced from a local health food shop, oat milk for coffee. The earlier you mention your needs, the better the result.
Choose your restaurant tier wisely. Modern medina restaurants in Marrakech (Nomad, Le Jardin, Café des Épices) have English-speaking front of house and chefs used to adapting for dietary needs. Traditional neighbourhood restaurants offer fantastic food but less English and less flexibility on the fly.
Be explicit about cross-contamination. Moroccan cooks are genuinely accommodating, but the concept of coeliac-level cross-contamination — shared chopping boards, shared oil, shared pots — is not widely understood. Say clearly: "The pan must be clean, no shared cooking surface" rather than simply "no gluten."
Street food and nut allergy don't mix. The snack culture around Djemaa el-Fnaa — nut stalls, pastry sellers, sugared almond carts — makes cross-contamination effectively unavoidable. Nut-allergy travellers should treat the main square as a high-risk environment for eating.
Rural and desert legs need advance logistics. A private guided tour to the Sahara or Atlas Mountains is the single most effective tool for travellers with serious allergies or vegan requirements — your guide communicates with camp chefs in advance, confirms ingredients at each stop, and can source dedicated equipment where needed. Self-managed travel through rural Morocco with severe allergies carries meaningful risk.
