Gluten-Free Croque Madame
Make this gorgeous Gluten-Free Croque Madame at home with creamy béchamel, melty Gruyère, and a perfectly runny egg—easier than you think!
You know what? The first time I attempted a Croque Madame, I was convinced it was restaurant-only territory. All that creamy béchamel sauce, the perfectly melted cheese, that gorgeous sunny-side-up egg perched on top—it felt fancy and intimidating.
But here’s the thing: this Gluten-Free Croque Madame is surprisingly approachable, even on a busy weekday morning. It’s become my go-to for special weekend brunches and holidays like Mother’s Day or Easter, when I want something that looks impressive but doesn’t chain me to the stove for hours.
This classic French sandwich transforms simple ingredients into something truly spectacular. The combination of savory ham, nutty Gruyère, and that silky béchamel creates flavors as rich and comforting as your favorite childhood grilled cheese—but elevated. And yes, it’s completely gluten-free without sacrificing a single bit of that traditional taste or texture.

Ingredients
For the Sandwich
- 8 slices gluten-free bread
- 8 tbsp unsalted butter softened
- 12 slices gluten-free ham e.g., Boar’s Head
- 2 cup shredded Gruyère cheese or a suitable gluten-free alternative
- 4 large eggs
- fresh chives chopped for garnish
- microgreens for serving, optional
- freshly cracked black pepper for serving
For the Gluten-Free Béchamel Sauce
- 3 tbsp unsalted butter
- 1½ tbsp gluten-free all-purpose flour
- 1 cup whole milk
- 2 tbsp gluten-free Dijon mustard
- ½ tsp kosher salt
- ⅛ tsp ground nutmeg
Instructions
- Set your oven to 375°F and position a rack in the center. This temperature gives you perfectly golden bread without drying out the ham or overcooking the cheese.
- In a medium skillet over medium heat, melt 3 tablespoons of butter until it’s just bubbling. Add the gluten-free all-purpose flour and whisk continuously for about 30 seconds—you’re creating a roux that’ll thicken your sauce beautifully. Gradually pour in the milk while whisking constantly to prevent lumps, then cook until the sauce thickens enough to coat the back of a spoon (about 4 minutes). Remove from heat and stir in the Dijon mustard, salt, and nutmeg for that classic French flavor.
- Spread softened butter generously on one side of each bread slice—this creates that irresistible golden crust. Place four slices buttered-side down on a baking sheet, then layer with ham and a generous portion of shredded Gruyère on each. Top with the remaining bread slices, buttered-side up, creating neat little packages.
- Slide your baking sheet into the oven and bake for about 6 minutes. You’re looking for golden-brown bread and cheese that’s just starting to melt and get gooey—the aroma will be absolutely mouthwatering.
- Remove sandwiches from the oven and spread that luscious béchamel sauce evenly over the top of each one. Sprinkle with extra Gruyère if you’re feeling indulgent (and honestly, why not?). Switch your oven to broil and return the sandwiches until the cheese bubbles and develops golden-brown spots, about 3-4 minutes—watch carefully so they don’t burn.
- While your sandwiches broil, heat a bit of butter or oil in a skillet over medium heat. Crack your eggs into the pan, leaving space between them, and fry gently until the whites are completely set but those yolks remain gloriously runny (about 5 minutes). The yolk acts as a built-in sauce when you cut into your Gluten-Free Croque Madame.
- Carefully place one fried egg on top of each sandwich, then garnish with chopped fresh chives, microgreens if you have them, and a few cracks of black pepper. Serve right away while everything’s hot and that egg yolk is ready to cascade down the sides.

| Whole milk | 1 cup |
| Gluten-free Dijon mustard | 2 tbsp |
| Kosher salt | ½ tsp |
| Ground nutmeg | ⅛ tsp |
Instructions
Step 1: Preheat Your Oven Set your oven to 375°F and position a rack in the center. This temperature gives you perfectly golden bread without drying out the ham or overcooking the cheese.
Step 2: Make the Béchamel Sauce In a medium skillet over medium heat, melt 3 tablespoons of butter until it’s just bubbling. Add the gluten-free all-purpose flour and whisk continuously for about 30 seconds—you’re creating a roux that’ll thicken your sauce beautifully. Gradually pour in the milk while whisking constantly to prevent lumps, then cook until the sauce thickens enough to coat the back of a spoon (about 4 minutes). Remove from heat and stir in the Dijon mustard, salt, and nutmeg for that classic French flavor.
Step 3: Assemble the Sandwiches Spread softened butter generously on one side of each bread slice—this creates that irresistible golden crust. Place four slices buttered-side down on a baking sheet, then layer with ham and a generous portion of shredded Gruyère on each. Top with the remaining bread slices, buttered-side up, creating neat little packages.
Step 4: Bake Until Golden Slide your baking sheet into the oven and bake for about 6 minutes. You’re looking for golden-brown bread and cheese that’s just starting to melt and get gooey—the aroma will be absolutely mouthwatering.
Step 5: Add Béchamel and Broil Remove sandwiches from the oven and spread that luscious béchamel sauce evenly over the top of each one. Sprinkle with extra Gruyère if you’re feeling indulgent (and honestly, why not?). Switch your oven to broil and return the sandwiches until the cheese bubbles and develops golden-brown spots, about 3-4 minutes—watch carefully so they don’t burn.
Step 6: Fry the Eggs While your sandwiches broil, heat a bit of butter or oil in a skillet over medium heat. Crack your eggs into the pan, leaving space between them, and fry gently until the whites are completely set but those yolks remain gloriously runny (about 5 minutes). The yolk acts as a built-in sauce when you cut into your Gluten-Free Croque Madame.
Step 7: Serve Immediately Carefully place one fried egg on top of each sandwich, then garnish with chopped fresh chives, microgreens if you have them, and a few cracks of black pepper. Serve right away while everything’s hot and that egg yolk is ready to cascade down the sides.
Substitutions
Bread Options If you’re following our complete gluten-free baking guide, you know that bread choice matters tremendously in this recipe. Look for a sturdy gluten-free sandwich bread that won’t get soggy under all that béchamel—brands like Canyon Bakehouse or Schar work beautifully.
Cheese Alternatives Gruyère brings that nutty, slightly sweet flavor that’s traditional in brunch lunch recipes, but Swiss cheese makes an excellent substitute if that’s what you have on hand. For a dairy-free version, try a high-quality aged cashew-based cheese that melts well.
Ham Swaps Turkey or chicken slices work wonderfully if you prefer poultry, and they still give you that savory protein element. For a vegetarian Gluten-Free Croque Madame, try thick slices of roasted portobello mushrooms or sautéed spinach with caramelized onions.
Flour for Béchamel Any gluten-free all-purpose flour blend works in the béchamel sauce—just make sure it contains xanthan gum for proper thickening. You can also use sweet rice flour (not regular rice flour) for an ultra-smooth sauce.
Troubleshooting
Béchamel Sauce Too Thick or Lumpy Well… if your sauce seized up on you, don’t panic. Whisk in an extra tablespoon or two of warm milk until it reaches that silky, pourable consistency. The key is adding the milk gradually while whisking constantly—rushing this step is what creates lumps.
Bread Getting Too Crispy If your gluten-free bread browns too quickly in the oven, tent it loosely with foil during the initial bake. Some gluten-free breads are more delicate and toast faster than traditional wheat bread, so keep a close eye after the 4-minute mark.
Runny Eggs Breaking For foolproof fried eggs, use the freshest eggs possible and a non-stick skillet with a lid. Cover the pan for the last minute of cooking to gently steam the tops while keeping those yolks soft—this technique from expert breakfast cooking strategies works every time.
Cheese Not Melting Properly Make sure your cheese is finely shredded, not in thick chunks, for even melting throughout your cute healthy breakfast creation. Bringing cheese to room temperature before assembling also helps it melt more uniformly.
Storage and Meal Prep
Storing Leftovers Man, oh man, while this Gluten-Free Croque Madame is best enjoyed fresh, you can store assembled sandwiches (without the egg) wrapped tightly in the refrigerator for up to 2 days. The béchamel sauce keeps well in an airtight container for up to 3 days—just give it a gentle reheat and whisk before using.
Meal Prep Tips You can absolutely prep components ahead to streamline your morning routine. Make the béchamel sauce the night before and store it covered in the fridge. Assemble sandwiches up to the point of baking, then cover and refrigerate—just add a few extra minutes to the baking time if they’re going in cold.
Serving Suggestions
Serve your Gluten-Free Croque Madame alongside a crisp green salad dressed with Dijon vinaigrette to balance all that richness. A simple arugula salad with lemon and shaved Parmesan echoes the French café vibe perfectly.
Fresh fruit like sliced strawberries or a handful of grapes adds a refreshing sweetness that cuts through the savory flavors beautifully. For a heartier meal, add roasted breakfast potatoes or our Paleo Whole30 Egg Potato Boats on the side for a complete brunch spread.
Variations
Kid-Friendly Version Tone down the Dijon mustard in the béchamel to just 1 tablespoon for younger palates who might find the traditional version too tangy. You can also skip the runny egg on top and serve it as a regular Croque Monsieur instead—still delicious and way less messy for little ones learning cooking skills at the kitchen recipes table.
Dairy-Free Adaptation Swap regular butter for vegan butter, use unsweetened almond or oat milk in the béchamel, and choose a melty dairy-free cheese. Brands like Violife or Miyoko’s create that stretchy, gooey texture you want in this classic sandwich.
Lighter Option Use a lighter cheese like part-skim mozzarella instead of Gruyère, and make your béchamel with 2% milk. You’ll still get fantastic flavor while cutting some of the richness—perfect if you’re watching your intake but don’t want to miss out on this elegant brunch experience.
Veggie-Packed Version Layer in some sautéed mushrooms, wilted spinach, or thinly sliced tomatoes along with the ham for extra nutrition and flavor. This turns your Gluten-Free Croque Madame into an even more substantial meal that incorporates more vegetables naturally.
Gluten-Free Croque Madame FAQs
Can I make this recipe ahead for a brunch party?
Absolutely! Assemble the sandwiches completely (minus the eggs) and refrigerate them overnight. When guests arrive, bake them straight from the fridge, adding 2-3 extra minutes to the cooking time. Fry the eggs fresh just before serving so they’re perfectly runny.
What’s the difference between Croque Madame and Croque Monsieur?
The only difference is the egg on top—Croque Monsieur is the sandwich without the fried egg, while Croque Madame adds that beautiful sunny-side-up egg as a crown. Both feature the same delicious béchamel-covered ham and cheese combination that makes this French classic so beloved.
How do I keep the egg yolk runny when serving multiple people?
Cook your eggs in batches and keep them warm on a plate tented with foil while you finish the rest. Alternatively, fry all eggs in a large skillet simultaneously if you have the space—just work quickly to get them onto the sandwiches while they’re still at that perfect jammy consistency.
Best way to reheat leftover Croque Madame?
Reheat the sandwich portion in a 350°F oven for about 8-10 minutes until warmed through and the cheese re-melts. Always fry a fresh egg to top it—reheated eggs just don’t have the same appeal, and that runny yolk is really what makes this dish special.
What type of gluten-free bread works best for this recipe?
Look for a sturdy sandwich-style gluten-free bread that can hold up to butter, béchamel, and toppings without getting soggy. Our gluten-free artisan bread recipe creates an ideal texture, or brands like Canyon Bakehouse Heritage Style deliver excellent results with a soft interior and structure that crisps beautifully.
Why is my béchamel sauce grainy?
A grainy béchamel usually means the sauce got too hot or the flour wasn’t whisked in thoroughly at the beginning. Keep your heat at medium (never high) and whisk continuously as you add the milk—patience here rewards you with a sauce as smooth and velvety as silk.
This Gluten-Free Croque Madame proves that elegant French cuisine absolutely has a place in your gluten-free kitchen. Whether you’re celebrating a special occasion or just treating yourself to a luxurious weekend breakfast, this recipe delivers restaurant-quality results with straightforward techniques.
The beauty of mastering this classic is how easily you can adapt it to your family’s preferences—add vegetables, swap proteins, or adjust the richness to suit your needs. Once you’ve got the basic method down, you’ll find yourself reaching for this impressive yet achievable recipe again and again.
