Gluten-Free Croque Monsieur Galette — The Classic, Reengineered with Attitude
Gluten-Free Croque Monsieur Galette — this one started on an ordinary weekday.
Not a holiday, not a celebration. Just a rainy fall afternoon, the house quiet, the coffee doing its job, and my brain suddenly insisting:
You know what would fix everything? Ham. And cheese. And béchamel.
The problem? The classics don’t always show up gluten-free.
Which means if you want a Croque Monsieur with all the melty, cheesy, béchamel-heavy satisfaction… sometimes you have to rebuild it from the ground up.
So instead of wishing for the Croque Monsieur I could not serve, I decided to engineer the one I could — in galette form, because flaky crust solves problems therapy can’t.
I started layering: salty ham, silky béchamel, melty cheese. No egg this time. No need. This version doesn’t whisper — it shows up with a wink and a little attitude, like, “Did somebody order satisfaction?”
And when it came out of the oven — golden, bubbling, edges crisp and proud — it was exactly right.
Savory enough to feel indulgent.
Simple enough to rescue a random weekday dinner.
Grown-up enough to serve guests.
Chaotic enough that you’ll probably eat it standing at the counter at least once.
That’s the soul of this gluten-free Croque Monsieur galette:
comfort, confidence, and the kind of melty-cheesy joy that doesn’t wait for an occasion.

What Makes This Galette Special
Because some meals deserve to be remembered — and this one was unforgettable, bold and cheesy.
This Gluten-Free Croque Monsieur Galette takes everything I love about the classic French bistro sandwich, (the buttery toast, the melted cheese, the silky béchamel) and gives it a new life in a flaky, gluten-free crust.
- Flaky gluten-free crust that doesn’t crumble under pressure. It holds up beautifully, even with béchamel and melted cheese involved.
- Savory, balanced filling — salty ham, creamy sauce, and nutty cheese in every bite.
- Perfect for any time of day — brunch, lunch, or a cozy dinner-for-two… or you know a midnight snack.
Ingredients You’ll Need to Make this Gluten-Free Croque Monsieur Galette
Dough:
- Gluten-Free Galette Dough (½ batch): The sturdy, flaky backbone that holds everything together. Use my recipe or your favorite trusted recipe.
- 1 egg white, beaten: The classic egg wash for that golden sheen
- Kosher salt & freshly ground black pepper: The finishing touch — never skip them
Béchamel:
- 2 Tbsp unsalted butter: Because flavor starts with fat
- 2 Tbsp gluten-free flour: The thickener that makes your sauce silky, not stodgy
- 1½ cups whole milk (warm): The base that turns everything luxuriously smooth
- 1 oz grated Parmesan: Adds saltiness and umami depth
- 4 oz grated Gruyère or Emmental: For that quintessential melt and stretch
- Dash of nutmeg: A whisper of warmth that makes the sauce French, not bland
- Kosher salt & freshly ground black pepper: Season to taste — taste again
Filling:
- 1 Tbsp olive oil: Helps to prevent a soggy bottom on your galette
- 3 Tbsp Dijon mustard: Bright, sharp, unapologetically French
- 1 Tbsp mayonnaise: Adds richness and smooths the edges
- 4 oz grated Gruyère or Emmental (additional): Because too much cheese is not a real thing
- 8 slices French ham (thin): Salty, savory, the supporting actor that deserves top billing
- Fresh thyme: For garnish and a bit of herbal restraint
- Kosher salt & pepper: Always to taste
Equipment You’ll Need to Make This Galette
- Food Processor, Box Grater or Pastry Cutter: To blend butter into the crust like a pro
- Rolling Pin: To get that rustic, even crust…rustic imperfection!
- Baking Sheet + Parchment Paper: For golden, mess-free edges
- Medium saucepan: For making that creamy béchamel
- Whisk: Non-negotiable… clumps are not invited
- Cheese grater: Freshly grated cheese melts like a dream
- Ramekin or small bowl: For your Dijon-mayo mix
- Pastry brush: For the egg wash and pro-level crust shine
- Sharp knife and cutting board: You’ll need both
Substitution Ideas and Variations
- Cheese: Try Comté, Swiss, or sharp cheddar for different moods
- Milk: 2% + a spoonful of sour cream or Greek yogurt for creaminess. Oat or unsweetened almond milk works for a lighter, dairy-reduced version
- Ham: Smoked turkey or prosciutto if you want to switch the salt/smoke profile, or go meatless
- Béchamel: You can skip it, but it’s the soul of the dish
What to Serve with Gluten-Free Croque Monsieur Galette
This galette is king — and pairs well with the queen (Croque Madame Galette). It simply hats (or crowns off)… no eggs on top!
If you’re feeling extra, try:
- Crisp green salad with lemon-Dijon or shallot vinaigrette to balance the richness
- Quick-pickled cucumbers or cornichons for a tangy snap
- Roasted asparagus or sautéed spinach for something green and elegant
- A glass of crisp white wine or afternoon café au lait — both work, both win
- Bonus: nothing… let the yolk be your sauce and the galette do the talking.
- Add an egg and you have Croque Madame Galette
Hosting brunch? Pair it with coffee and my Gluten-Free Lemon Icebox Pie for a sweet-and-savory duo that’ll make your table look like a Parisian bakery window.

Ingredients
Gluten Free Dough
Béchamel
Filling/Assembly
Instructions
Prep the Gluten-Free Crust
-
- I Prepare a single gluten-free pie crust according to the double-crust recipe found here.
- Rather than one galette, I made 4 mini-galettes out of 1/2 of the recipe. Divide the dough round by 4 and roll each out to a thickness of 1/8" into a circle approximately 5-6” in diameter.
- Line a baking sheet with parchment paper; Transfer the rolled out dough to the prepared baking sheet.
Make the Béchamel
-
- In a medium saucepan, melt 2 Tbsp butter over medium heat.
- Whisk in 2 Tbsp gluten-free flour and cook for 1–2 minutes (do not brown).
- Gradually whisk in 1 1⁄2 cups warm milk until smooth and thickened.
- Stir in ¾ oz Parmesan and 4 oz Emmental or Gruyère; add a dash of nutmeg.
- Season with salt and pepper. Remove from heat and set aside.
Assemble
-
- Spread 1 Tbsp olive oil over the rolled out dough. If making mini-galettes use approximately 1 teaspoon per round.
- Mix 3 Tbsp Dijon, and 1 Tbsp mayo in a ramekin. Brush the center of each dough round with this mustard mayo mix.
- Sprinkle ~2 oz grated Emmental or Gruyère over the mustard base. Arrange slices of ham across the cheese (overlap to cover).
- Spoon about 2–3 Tbsp béchamel over the ham (don’t drown it — you want balance).
- Sprinkle remaining grated cheese. Season with thyme.
- Fold the edges up gently around the filling. Brush the crust with egg wash. Dust with salt and pepper.
Bake
-
- Bake at 350°F (200°C) for 30-35 minutes, until crust begins to turn golden.
- Remove from the oven.
- Let the galettes cool for no more than 5 minutes before serving.
Note
Gluten-Free Flours
When it comes to baking gluten-free, the type of flour you use can significantly impact the texture and flavor of your final product. Here are some important tips regarding gluten-free flours for your Banana Bread recipe:
1. Homemade Flour Blend
I use a custom gluten-free flour blend that I make myself, which weighs approximately 140 grams per cup. This blend typically includes a mix of gluten-free flours such as white and brown rice flour, potato starch, tapioca starch, sorghum and milk powder, providing a balanced texture and flavor for baking.
2. Store-Bought Gluten-Free Flours
If you prefer to use a store-bought gluten-free flour blend, it's crucial to check the packaging for the weight per cup, as this can vary between brands. Each manufacturer may have a different formulation, which affects the density and weight of their flour.
Here are several that are available from Amazon:
King Arthur Measure for Measure Gluten-Free Flour
Bob’s Red Mill Gluten Free 1 to 1 Baking Flour
Cup4Cup Gluten Free Multipurpose Flour
None of these flours contain xanthan gum. So if your recipe calls for xanthan gum, omit the extra xanthan if using one of these blends. All of the manufacturers promote these products as a one-to-one replacement.
3. Measuring for Accuracy
For the most accurate results, I highly recommend using a digital food scale to measure your gluten-free flour. Measuring by weight ensures that you have the correct amount, leading to more consistent and successful baking outcomes. This method eliminates the variability that can come from measuring by volume, especially with gluten-free flours, which can be compacted or aerated differently.
By paying attention to these details, you'll set yourself up for success in creating a delicious and moist Gluten-Free Banana Bread. Happy baking!
Kosher Salt
You can use kosher salt in this recipe; however, the crystal of table salt and kosher salt are not the same. So a teaspoon of one is not the same as a teaspoon of the other. Here are equivalents for two commonly available kosher salt brands:
To Replace: 1 teaspoon table salt
• 2 teaspoon diamond Crystal Kosher Salt
• 1 1/2 teaspoons Morton Kosher Salt

Frequently Asked Questions
What is a gluten-free galette?
It’s a rustic, freeform tart made with gluten-free dough folded around savory or sweet fillings, baked until golden and flaky.
Can I use regular all-purpose flour instead of gluten-free flour for the dough?
Yes, you can use regular all-purpose flour if you don't have dietary restrictions.
I'm vegan. Can I make this galette without dairy and eggs?
Yes you can! You can make this without ham or explore a vegetarian meat solution, use non-dairy cheese and eliminate the egg wash. This however, will significantly change the flavor of this galette. You might choose a less meat and dairy heavy galette.
Can I use store-bought gluten-free dough?
Finding gluten-free dough in the grocery store can be a challenge. However, if you do find it, just make sure it’s sturdy enough to hold the filling without cracking.
Q: What’s the best way to reheat leftovers?
Warm gently in a 350°F oven for 10 minutes to keep the crust crisp and the cheese melty.
What is the purpose of xanthan gum in gluten-free baking?
Xanthan gum is a common additive in gluten-free baking. It helps mimic the binding and elasticity properties of gluten, improving the texture and structure of gluten-free baked goods.
Can I freeze the galette for later?
Yes, you can freeze the galette. Wrap it tightly in plastic wrap and aluminum foil or place it in an airtight container before freezing. It should be good for up to 2-3 months. Thaw in the refrigerator before reheating.
Can I scale this recipe for a larger galette?
Rather than making a larger galette - which would be difficult to handle, make a second galette.
Can I swap the béchamel for something quicker?
A thin layer of good mayo plus extra cheese will sort you in a pinch, but béchamel is the mood.
Is this actually flaky if it’s gluten-free?
If your galette dough recipe is solid, yes — it’ll flake and hold. Chill that dough and don’t overwork it. Pro Tip: Rustic folds = charm. Don’t fuss. Perfection is boring.
