Can you eat croque monsieur while pregnant?
Check firstYes, a croque monsieur is safe when it arrives hot and bubbling, with the ham heated right through. Skip one sold cold or lukewarm from a display case unless you can warm it until it steams.
Why
The cheese is not the issue. Gruyere is a hard cheese the NHS lists as safe, and the bechamel is cooked from pasteurized milk. The ham is the part that needs heat. Sliced cooked ham is a deli meat, and the CDC advises pregnant people to heat deli meats to 165 F, or until steaming hot, because Listeria can keep growing in them even in the fridge. A croque baked or grilled to order gets that hot. One made hours earlier and served at room temperature does not. On a croque madame, the fried egg on top needs its own check: FoodSafety.gov advises cooking eggs until the yolk and white are firm to rule out Salmonella.
Safer alternatives
- A grilled cheese made with Gruyere or cheddar
- A hot ham and Swiss panini pressed until steaming
- Baked mac and cheese topped with Gruyere

Frequently asked questions
Is a croque madame safe while pregnant?
Yes, if the fried egg on top is cooked until the yolk is set. Many cafes serve it runny, so ask for the egg well done. At home, a runny yolk is fine if you use pasteurized eggs.
Is the cheese in a croque monsieur safe during pregnancy?
Yes. The classic choice is Gruyere, a hard cheese the NHS lists as safe, and the bechamel sauce is simmered from pasteurized milk. Both get melted hot under the grill, which adds an extra margin of safety.
Can I eat a cold croque monsieur from a bakery case?
Warm it first. The ham inside is a deli meat, and Listeria can grow in it once the sandwich has cooled. Heat it in the oven or toaster oven until the center is steaming hot.
