This mouthwatering maple mustard breakfast sandwich on croissants has totally changed my weekend mornings, turning regular breakfasts into something special without much work. The mix of flaky croissants with that sweet-tangy maple mustard combo makes for a breakfast that feels fancy but comes together super quick.
I came up with these sandwiches while putting together a surprise birthday brunch for my sister. Everybody asked for my recipe before they'd even finished eating, and now we make them whenever there's something to celebrate in our family.
Ingredients
- Croissants: Grab them fresh from a nearby bakery for that amazing buttery texture that makes these sandwiches stand out.
- Large eggs: They add protein and create a soft layer that works well with the rich croissant.
- Bacon: Cook it till it's nice and crispy for that amazing crunch and smoky taste.
- Maple syrup: Adds natural sweetness that goes great with all the savory stuff.
- Dijon mustard: Brings a zingy kick that balances out the richness.
- Cheddar cheese: Gets all gooey when melted and adds that sharp flavor that pulls everything together.
- Butter: For cooking your eggs so they stay juicy and tasty.
- Salt and pepper: You can't skip these for making your eggs taste good.
Step-by-Step Instructions
- Prepare the Croissants:
- Cut each croissant sideways with a bread knife for a clean slice. Try to keep the top part a bit thicker than the bottom so your fillings don't make it soggy.
- Cook the Bacon:
- Put your bacon strips in a cold pan then turn the heat to medium and let them cook until they're as crispy as you want. Starting with a cold pan helps the fat cook out evenly for super crispy bacon. Put them on paper towels to soak up extra grease.
- Create the Maple Mustard Sauce:
- Mix your maple syrup and Dijon in a small pot over low heat. Keep stirring for about 2 minutes until everything blends and gets a little thick. Let it sit for a minute since it'll thicken up more as it cools.
- Prepare the Eggs:
- Beat your eggs really well with salt and pepper until they're foamy. Melt some butter in a non-stick pan over medium-low heat. Pour in your eggs and gently fold them as they cook for about 2 minutes until they're just set but still soft.
- Assemble the Sandwiches:
- Smear plenty of maple mustard sauce on the bottom half of each croissant. Add 2 pieces of bacon broken to fit, then add some fluffy eggs. Put a slice of cheddar on the warm eggs so it starts to melt.
- Final Touch:
- Put your sandwiches on a baking sheet and warm them in a 350°F oven for 5 minutes. You don't have to do this step, but it's worth it because the cheese gets all melty and everything warms up just right.

That maple mustard sauce is really the hidden gem in this recipe. I found it by chance when I ran out of my regular spreads and had to get creative. It turned out so good that I now make big batches to put on everything from sandwiches to roasted veggies.
Make Ahead Options
These sandwiches taste best when they're fresh, but you can get most things ready ahead of time for quick assembly. Cook your bacon and mix up the maple mustard sauce up to three days early. Keep them in sealed containers in the fridge. When you're ready to eat, just warm the bacon in the microwave or oven before putting everything together. It's best to cook the eggs right when you need them for the right texture and taste.
Perfect Pairings
These breakfast sandwiches are great on their own but go really well with fresh fruit for a complete breakfast. Some mixed berries or sliced melon gives a nice fresh contrast to the rich sandwich. For special occasions, serve them with a small arugula salad with lemon dressing or a side of breakfast potatoes. Fresh orange juice or hot coffee goes wonderfully with the sweet and savory flavors.

Customization Ideas
What's great about these breakfast sandwiches is how easy they are to change up. If you want some heat, add a splash of hot sauce to the maple mustard mix or throw in some thin jalapeño slices. If you don't eat meat, skip the bacon or use avocado slices instead for creaminess. Want something heartier? Add a thin slice of ham along with the bacon. In summer, try adding a slice of juicy tomato or some fresh basil for brightness.
Common Questions
- → Can I swap out the croissants for something else?
Absolutely! Try using brioche buns, toasted bagels, or thick slices of sourdough if you want a different base for your sandwich.
- → How can I make the mustard mixture less sweet?
Cut back on the maple syrup or add a little lemon juice to bring more tang to the sauce.
- → Is it possible to make these sandwiches beforehand?
Sure thing! You can get all the parts ready, put your sandwiches together, wrap them up tight, and warm them in the oven when you're ready to eat.
- → What's a good substitute for bacon?
You can swap in turkey bacon, sliced ham, or even veggie bacon alternatives to get that savory kick.
- → Any tips for making extra fluffy eggs?
Beat your eggs really well before cooking and keep the heat low while you stir them constantly—this gets you that soft, cloud-like texture.
