What You'll Need for Crispy Croque Madame with Béchamel and Runny Egg
Choosing the right ingredients makes a big difference, but this recipe is forgiving enough to work with what you have.
- 4 slices brioche bread, 1/2 inch thick
- 8 oz Black Forest ham, thinly sliced
- 1 1/2 cups whole milk
- 4 tbsp unsalted butter
- 1/4 cup all-purpose flour
- 1 1/2 cups grated Gruyère cheese
- 2 large eggs
- 1/4 tsp freshly grated nutmeg
- 1/2 tsp Dijon mustard
- 1/4 tsp white pepper
- 1/2 tsp kosher salt
- Optional: Fresh chives, finely snipped
- Optional: Micro arugula
- Optional: Dash of cayenne
📝 Ingredient Notes
- Brioche: Must be slightly stale — fresh brioche absorbs too much béchamel and turns gummy.
- Gruyère: Do not substitute pre-shredded: it contains anti-caking starch that prevents smooth melting.
🛒 Tools & Equipment I Recommend
- All-Clad Stainless Steel Saucepan — Even heat prevents béchamel from scorching or lumping — a $120 pan that pays for itself after 3 takeout croque madames → See on Amazon
- Microplane Fine Grater — Grates cold Gruyère into feathery shreds that melt evenly — avoids clumps or bare spots → See on Amazon
How to Make Crispy Croque Madame with Béchamel and Runny Egg
- Make béchamel: Melt butter in saucepan over medium-low heat. Whisk in flour; cook 2 minutes until paste smells nutty. Gradually whisk in warm milk. Simmer 8–10 minutes, stirring constantly, until thick enough to coat spoon. Stir in nutmeg, mustard, salt, and white pepper. Cool 10 minutes.
- Assemble sandwiches: Butter one side of each brioche slice. Flip buttered side down on baking sheet. Top with 2 oz ham per slice. Ladle 1/4 cup béchamel over ham. Sprinkle with 1/4 cup Gruyère per sandwich.
- Bake: Preheat oven to 425°F. Bake 12 minutes until cheese bubbles and edges begin to crisp. Remove, carefully crack one egg onto each sandwich. Return to oven 3–4 minutes until egg white is set but yolk is still runny.
- Broil finish: Switch oven to broil. Broil 45–60 seconds — watch closely — until cheese is deeply golden with crisp lacy edges.
Cook's Tips for Perfect Crispy Croque Madame with Béchamel and Runny Egg
- Texture control: Bake on a preheated baking sheet — it delivers immediate bottom heat to crisp the bread before the béchamel softens it.
- Common mistake and fix: The #1 reason this fails is béchamel that’s too thin. If it pools or slides off the ham, it’s undercooked — simmer 2 more minutes and cool fully before using.
- Egg timing: Crack eggs into a ramekin first, then pour onto hot sandwiches — avoids tearing the ham or displacing cheese.
- Cheese application: Sprinkle half the Gruyère before the egg, half after — ensures top crust is thick and shatter-crisp.
Storing & Reheating Crispy Croque Madame with Béchamel and Runny Egg
Short-Term Storage
Store in an airtight container in the fridge. Store assembled but unbaked sandwiches covered in fridge up to 24 hours. Make-ahead tip: Make béchamel up to 2 days ahead. Cover surface with parchment, chill, then rewarm gently before assembling.
Freezing Crispy Croque Madame with Béchamel and Runny Egg
Do not freeze — béchamel separates and bread turns gummy.
How to Reheat Without Drying It Out
Oven: Bake at 375°F for 8 minutes, then broil 45 seconds for crispness. Microwave: Not recommended — makes bread rubbery and cheese greasy.
Recipe Notes
- Chef tip: Warm the milk before adding — cold milk shocks the roux and causes lumps every time.
- Best substitution: Use Emmental if Gruyère is unavailable — it melts similarly but is milder. Avoid Swiss — it’s too sharp and dries out.
- Make-ahead: Assemble sandwiches and refrigerate up to 12 hours. Add egg and bake just before serving.
- Scaling: For 8 servings: double all ingredients but bake in two batches — overcrowding lowers oven temp and steams the crust.
- Troubleshooting: If cheese doesn’t crisp: your oven runs cool. Calibrate or bake at 450°F. If egg overcooks: remove from oven at 2:45 minutes — residual heat finishes it.

Crispy Croque Madame with Béchamel and Runny Egg FAQs
You can prep béchamel and assemble sandwiches up to 12 hours ahead. But do not add the egg until right before baking — it will weep and make the top soggy. Store covered in the fridge and bake straight from cold.
Soggy bread means either the béchamel was too thin or the bread wasn’t slightly stale. Thin béchamel soaks in. Use day-old brioche — it holds structure. Preheat your baking sheet for instant bottom crispness.
Yes — but only for reheating or crisping leftovers. The air fryer can’t properly set the egg or melt cheese evenly on top. Use oven for full recipe, air fryer only for 3-minute crisp-up of leftovers.
Emmental or Comté are closest. Avoid cheddar — it becomes oily, and mozzarella won’t brown properly. Grate it yourself: pre-shredded contains cellulose that blocks melting.
It’s a cozy, hearty winter favorite — the rich béchamel and melted cheese warm you from the inside. Serve it on cold mornings with a simple green salad for balance.
