A croque madame was one of those dishes I always assumed I had to give up. Bistro food. Bread-and-cheese food. The kind of thing that feels completely off-limits when you pull grains and dairy out of your life. But the flavors, the savory ham, that rich creamy sauce, the fried egg sitting on top like it owns the place, those are worth fighting for. So I reverse-engineered the whole thing from the ground up. Here is what I swapped and why it works. The bread is a simple almond flour loaf baked in a standard pan and sliced. It toasts up firm and golden in a skillet with ghee, and it holds the sandwich together without turning into mush. That was the big test, and it passes. The bechamel is cashew-based, blended smooth with chicken broth, ghee, Dijon, garlic, and a pinch of nutmeg, just like the classic. It thickens when you warm it and broils up beautifully over the top of the sandwich. No dairy needed, no flavor compromised. And instead of the deli ham the French traditionally use, I reach for prosciutto, which gives you that same salty, savory layer but with better ingredients and more depth. The egg on top is non-negotiable. That runny yolk breaking over the bechamel is the whole point. This is a weekend breakfast, a slow Sunday morning, the kind of thing you make when you want to feel like you are sitting at a little table in Paris without the gluten hangover on Monday.


Nutritional Benefits

Almond Flour

  • Rich in vitamin E, a fat-soluble antioxidant that supports skin and cellular health.
  • Naturally low in carbohydrates and higher in protein and healthy fats than conventional wheat flour.
  • Contains magnesium, which most Americans are chronically short on.

Cashews (Bechamel Base)

  • Provide a creamy texture from their natural fat content without any dairy.
  • A good source of copper, which supports connective tissue and immune function.
  • Contain plant-based iron and zinc, both important for energy and immunity.

Eggs

  • One of the most complete protein sources in nature, with all essential amino acids.
  • Egg yolks are loaded with choline, a critical nutrient for brain health and liver function that most people do not get enough of.
  • Provide fat-soluble vitamins A, D, E, and K2, especially from pasture-raised sources.

Prosciutto

  • Made from just pork and salt, it is one of the cleanest deli-style meats you can buy.
  • Provides a meaningful hit of protein and fat to start the day.
  • No fillers, no nitrates added, and no mystery ingredients when you buy a quality brand.

Ghee

  • Clarified butter with the milk solids removed, making it suitable for most dairy-sensitive people.
  • A natural source of fat-soluble vitamins and butyrate, a short-chain fatty acid that supports gut lining health.
  • Has a high smoke point, making it ideal for toasting and frying without oxidizing.

FAQs

Can I make the almond flour bread ahead of time?

Yes, and I actually recommend it. Bake the loaf the day before, cool it completely, and refrigerate it. Cold bread slices cleaner and toasts up even better than bread that is still fresh from the oven.

Can I make the cashew bechamel ahead?

Absolutely. Blend it up to 3 days ahead and store it in a sealed jar in the fridge. Reheat gently on the stove over low heat, stirring, and add a splash of broth if it has thickened too much.

My bechamel is grainy. What went wrong?

The cashews need enough soaking time and a truly high-powered blender to get silky smooth. If yours is grainy, blend longer, or strain it through a fine mesh strainer. A Vitamix or Blendtec will give you the best result.

Can I use turkey or ham instead of prosciutto?

You can use any clean, minimally processed deli meat. Just read the label and avoid anything with added sugars, fillers, or nitrates. Prosciutto is my first pick because the ingredients are almost always just pork and salt.

Is this Whole30 compliant?

Not in its standard form because of the Dijon mustard, which can contain white wine. Check your mustard label. Some brands are Whole30 compliant and some are not. Swap to a compliant mustard and this dish qualifies.

What if I want a croque monsieur instead?

Skip the fried egg. Everything else stays exactly the same. The croque monsieur is the sandwich without the egg on top, and this version works beautifully either way.


If you made this, I want to know how it went. Drop a comment below and tell me if your egg was perfectly runny, because that is the real test. And if you are new here and just starting to figure out how to eat real food without giving up the dishes you love, stick around. That is exactly what we do.

Ingredients

  • **For the Almond Flour Sandwich Slices (makes 4 slices)**
  • 1 1/2 cups blanched almond flour
  • 2 tablespoons tapioca flour
  • 3 large eggs
  • 2 tablespoons ghee, melted (plus more for the pan)
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon fine sea salt
  • 1/2 teaspoon apple cider vinegar
  • **For the Cashew Bechamel**
  • 3/4 cup raw cashews, soaked in hot water for 20 minutes then drained
  • 1/2 cup chicken broth (unsalted)
  • 1 tablespoon ghee
  • 1 small clove garlic
  • 1 teaspoon Dijon mustard
  • 1/4 teaspoon onion powder
  • 1/4 teaspoon fine sea salt
  • Pinch of white pepper
  • Pinch of ground nutmeg
  • **For the Assembly**
  • 4 thin slices prosciutto
  • 2 teaspoons Dijon mustard
  • 2 large eggs
  • 1 tablespoon ghee
  • Flaky sea salt and cracked black pepper, to finish
  • Fresh chives, chopped, for garnish

Instructions

  1. Soak the cashews: Pour boiling water over the raw cashews and let them soak for at least 20 minutes while you prep everything else. Drain well before blending.
  2. Make the almond flour sandwich slices: Preheat your oven to 350°F. Line an 8x4-inch loaf pan with parchment paper and lightly grease it with ghee. In a large bowl, whisk together the almond flour, tapioca flour, baking soda, and salt. In a separate bowl, whisk the eggs, melted ghee, and apple cider vinegar until combined. Fold the wet ingredients into the dry until a thick batter forms. Pour into the prepared pan and smooth the top. Bake for 22 to 25 minutes, until the top is golden and a toothpick comes out clean. Cool for at least 10 minutes before slicing. Cut 4 even slices, roughly 3/4-inch thick, from the center of the loaf. Reserve the rest for another use.
  3. Make the cashew bechamel: Combine the drained cashews, chicken broth, ghee, garlic, Dijon, onion powder, salt, white pepper, and nutmeg in a high-speed blender. Blend on high for 60 to 90 seconds until completely smooth and silky. Taste and adjust salt. Transfer to a small saucepan and warm over low heat, stirring, until it thickens slightly, about 3 to 4 minutes. Remove from heat.
  4. Toast the bread slices: Heat a large skillet over medium heat and add a little ghee. Toast the 4 almond flour slices in batches for 2 to 3 minutes per side, until golden and firm. Set aside.
  5. Build the sandwiches: Spread a thin layer of Dijon mustard on one side of each of the 4 slices. Lay 2 slices of prosciutto on 2 of the bread slices, then spoon a generous tablespoon of cashew bechamel over the prosciutto. Top with the remaining bread slices, mustard-side down, to form 2 sandwiches.
  6. Broil with bechamel: Place the assembled sandwiches on a parchment-lined baking sheet. Spoon a generous layer of cashew bechamel over the top of each sandwich. Slide under the broiler for 2 to 3 minutes, watching closely, until the top is just starting to bubble and turn lightly golden in spots.
  7. Fry the eggs: While the sandwiches broil, melt 1 tablespoon ghee in a small non-stick skillet over medium-low heat. Fry 2 eggs sunny-side up until the whites are fully set but the yolks are still runny, about 3 minutes.
  8. Finish and serve: Remove the sandwiches from the broiler. Slide one fried egg on top of each sandwich. Finish with flaky sea salt, cracked black pepper, and a scatter of fresh chives. Serve immediately.
