Let’s Make it Together
Prepping the Ingredients
Start by gathering all your ingredients on the countertop so you can work efficiently. Slice the hard-boiled eggs into rounds, then set them aside. As you do this, let the smell of fresh croissants fill your kitchen.
Mixing Maple Mustard
In a small bowl, whisk together maple syrup and Dijon mustard until smooth. This mixture should be sweet yet tangy—taste it! Adjust as needed because who wouldn’t want to get this just right?
Toasting the Croissants
Slice each croissant in half horizontally. Place them cut-side up on a baking sheet and lightly toast them in an oven preheated to 350°F (175°C) until golden brown and fragrant—about 5 minutes will do!
Assembling Your Masterpiece
Spread a generous layer of your maple-mustard mix on both halves of each toasted croissant. Then layer on sliced avocado, fresh spinach, cheese slices, and egg rounds—make it as tall as you dare!
Final Touch
Top off each sandwich half with the other half of its croissant partner. If you want extra crunchiness (and who doesn’t?), pop them back in the oven for another minute or two so everything melts together beautifully.
Serve and Enjoy
Serve immediately while warm! Pair these sandwiches with fresh fruit or coffee for an unforgettable breakfast experience that’ll have everyone coming back for seconds.
These Killer Maple Mustard Croissant Breakfast Sandwiches are sure to become your new favorite morning treat—deliciously flaky and undeniably satisfying!
