Croque Monsieur
The story
Paris gave the world the croque monsieur: ham, Gruyere, and a blanket of béchamel broiled until it blisters. Beautiful. Also, historically, built on white bread that surrenders to all that molten glory in about ninety seconds. We love the classic. We just thought it deserved a better foundation than a slice destined for sog.
Enter the District Biscuit. Golden, flaky, engineered with crisp edges and honest-to-goodness layers that stand up to Dijon-spiked béchamel without waving a white napkin. Where bread goes limp and a muffin turns to paste, the biscuit holds its architecture, soaks up exactly enough sauce to get luscious, and keeps its shatter. Black Forest ham brings the smoke, Gruyere brings the nutty melt, and that Dijon cuts right through the richness like a maitre d' with somewhere to be.
This is lunch that thinks it's fine dining and brunch that skipped the line at the café. Your culinary canvas, now with a passport. Bonjour, indeed.

Ingredients
- 4 District Biscuits, warmed and split
- 8 oz Black Forest ham, thinly sliced
- 6 oz Gruyere, freshly grated (about 1.5 cups)
- 2 tbsp unsalted butter
- 2 tbsp all-purpose flour
- 1 cup whole milk, warmed
- 2 tbsp Dijon mustard
- Pinch of freshly grated nutmeg
- Salt and freshly ground black pepper, to taste
How to build it
-
1Warm and split the District Biscuits, then set the tops and bottoms cut-side up on a foil-lined baking sheet.
-
2Make the béchamel: melt the butter in a saucepan over medium heat, whisk in the flour, and cook 1 to 2 minutes until pale and nutty.
-
3Slowly whisk in the warm milk and cook, stirring, until the sauce thickens enough to coat the back of a spoon, about 3 to 4 minutes.
-
4Off the heat, whisk in the Dijon and nutmeg, season with salt and pepper, and stir in a handful of the grated Gruyere until smooth.
-
5Spread a spoonful of béchamel on each biscuit bottom, layer on the Black Forest ham, add a little more sauce, and cap with the biscuit tops.
-
6Spoon the remaining béchamel over the tops and blanket generously with the rest of the Gruyere.
-
7Broil 2 to 4 minutes, watching closely, until the cheese is bubbling, blistered, and golden.
-
8Let rest one minute, crack more black pepper over the top, and serve hot.
Pro tips & swaps
- Grate your own Gruyere off the block — pre-shredded cheese carries anti-caking starch that keeps it from melting into that glossy café finish.
- Warm the milk before it hits the roux; cold milk shocks the béchamel into lumps.
- Turn it into a Croque Madame by crowning each biscuit with a runny fried egg right before serving.
- Make the béchamel up to two days ahead and refrigerate; loosen it over low heat with a splash of milk before building.
- Keep your eyes on the broiler — the difference between golden-blistered and burnt is about ninety seconds.

Frequently asked questions
What is a Croque Monsieur biscuit?
It's the classic French café sandwich — Black Forest ham, Gruyere, and Dijon-spiked béchamel — reimagined on a golden, flaky District Biscuit instead of white bread. The béchamel gets broiled until bubbling and blistered on top. It's rich, smoky, and built for lunch or brunch.
Can I make a Croque Monsieur biscuit ahead of time?
Yes. Make the Dijon béchamel up to two days in advance and refrigerate it, then reheat gently with a splash of milk to loosen it. Assemble and broil just before serving so the District Biscuit stays crisp and flaky rather than sitting under sauce.
What's the best biscuit for a Croque Monsieur?
A sturdy, layered biscuit with crisp edges is essential because béchamel will turn softer breads to mush. The District Biscuit is engineered with flaky layers and structure that hold up under molten sauce without going soggy. That crisp-edge, tender-center contrast is exactly what this build needs.
What can I substitute for Gruyere in a Croque Monsieur?
Emmental, Comte, or a good Swiss all melt beautifully and keep that nutty French character. In a pinch, a sharp white cheddar works, though it reads a little less classic. Whatever you choose, grate it fresh off the block for the best melt.
Can I use a different ham than Black Forest?
Absolutely. Black Forest ham brings a smoky depth we love, but Parisian ham (jambon de Paris) is the most traditional choice and a touch milder. Any thinly sliced, good-quality deli ham will work on the District Biscuit base.
How do I make the béchamel smooth and not lumpy?
Cook the butter and flour together for a minute or two first, then whisk in warm milk slowly and steadily. Cold milk added too fast is the usual culprit behind lumps. Whisk constantly until it coats the back of a spoon, then stir in the Dijon and Gruyere off the heat.
What should I serve or drink with a Croque Monsieur biscuit?
A sharp, lightly dressed green salad or cornichons cut the richness perfectly. For drinks, a dry sparkling wine, a crisp white, or a proper cafe au lait all lean into the French vibe. For brunch, top it with a fried egg to make it a Croque Madame.
How do I store and reheat leftover Croque Monsieur biscuits?
Refrigerate leftovers in an airtight container for up to two days. Reheat in a 350F oven or toaster oven for about 8 to 10 minutes to bring back the crisp edges — the District Biscuit revives far better than bread would. Skip the microwave, which softens the flaky layers.
What makes a District Biscuit different?
District Biscuits are built with genuine flaky layers, crisp golden edges, and a tender center sturdy enough to carry saucy, ambitious builds like this one. Where bread or a muffin goes soggy, the District Biscuit holds its structure and shatter. That's why it's the ideal canvas — your culinary canvas — for a Croque Monsieur.
