This game-changing maple mustard croissant breakfast sandwich has turned my boring weekends around, making everyday mornings feel special without much work. When buttery croissants meet the sweet-tangy maple mustard mix, you get a quick but fancy breakfast that tastes like you spent hours in the kitchen.
I came up with these sandwiches while throwing a surprise birthday brunch for my sister. Folks were asking for the recipe with their mouths still full, and now we can't have a family celebration without them.
Ingredients
- Croissants: Get them fresh from nearby bakeries for that unbeatable flaky butteriness that makes these sandwiches so special.
- Large eggs: They add protein and create a soft layer that works well with the rich croissant.
- Bacon: Make it nice and crispy for that amazing crunch and smoky taste.
- Maple syrup: Adds a natural sweetness that works wonders with all the savory stuff.
- Dijon mustard: Brings that tangy kick that cuts through the richness of everything else.
- Cheddar cheese: It gets all melty and brings a sharp flavor that pulls everything together.
- Butter: Helps keep your eggs juicy and tasty when cooking.
- Salt and pepper: You need these basics to make your eggs taste their best.
Step-by-Step Instructions
- Prepare the Croissants:
- Cut each croissant sideways with a bread knife. Try to make the top part thicker than the bottom so your fillings don't soak through.
- Cook the Bacon:
- Put bacon in a skillet while it's still cold, then turn the heat to medium and cook until crispy. This slow-cooking trick makes perfectly crisp bacon every time. Put on paper towels to soak up extra grease.
- Create the Maple Mustard Sauce:
- Mix maple syrup and Dijon in a small pot over low heat. Keep stirring for about 2 minutes until everything blends and gets a bit thick. Let it sit for a minute as it'll thicken more.
- Prepare the Eggs:
- Beat eggs hard with salt and pepper until they're bubbly. Melt 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 set but still soft.
- Assemble the Sandwiches:
- Smear lots of maple mustard sauce on the bottom half of each croissant. Add 2 bacon strips broken to fit, then some fluffy eggs. Top with cheddar so it starts melting on the warm eggs.
- Final Touch:
- Put your assembled 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 really melts the cheese perfectly and warms everything up for the best breakfast experience.

That maple mustard sauce is really the hidden gem here. I found it by chance when I ran out of regular condiments 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 fresh, but you can get most things ready beforehand for quick assembly. You can cook the bacon and mix up the maple mustard sauce up to three days early. Keep them in sealed containers in your fridge. When you're hungry, just warm the bacon in the microwave or oven before putting everything together. For the best taste and texture, cook the eggs right when you need them.
Perfect Pairings
These breakfast sandwiches are great on their own but go really well with fresh fruit for a complete meal. Some mixed berries or cut melon gives a nice fresh contrast to the rich sandwich. For special days, serve with a light arugula salad with lemon dressing or a small side of breakfast potatoes. Fresh squeezed orange juice or hot coffee matches the sweet and savory flavors just right.

Customization Ideas
What makes these breakfast sandwiches so great is how easy they are to change up. Want something spicier? Add some hot sauce to the maple mustard mix or throw in thin slices of jalapeños. Don't eat meat? Skip the bacon or use avocado slices instead for creaminess. Need 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 croissants for different bread?
Absolutely! Try using brioche, bagels, or a couple slices of sourdough for a completely different taste experience.
- → How can I tone down the sweetness in the mustard mix?
Just cut back on the maple syrup or add a tiny bit of lemon juice to bring in some tang and balance the sweetness.
- → Is it possible to make these sandwiches beforehand?
For sure! You can get all parts ready, put them together, wrap them up tight, and warm them in the oven when you're ready to eat.
- → What works instead of bacon in this sandwich?
Try some turkey bacon, sliced ham, or even veggie bacon substitutes to get that same savory kick.
- → What's the trick for super fluffy eggs?
Beat those eggs really well before cooking and keep the heat low while stirring them around constantly to get that soft, cloud-like texture.
