This sweet-tangy maple mustard breakfast sandwich turns boring mornings into something special. The mix of flaky croissants, soft eggs, and a maple-mustard drizzle makes a cafe-quality breakfast you can enjoy without changing out of your PJs.
I came up with this idea one lazy weekend morning when I wanted something fancy but didn't feel like going out. Now my family asks for these sandwiches during weekend get-togethers and even birthday breakfasts.
Ingredients
- Croissants: Grab some from your local bakery for that perfect buttery crunch and soft inside
- Large eggs: Go for free-range ones if you can - they've got richer color and better taste
- Milk: Makes your eggs super creamy; full-fat works best here
- Turkey sausage patties: Already cooked so they're quick and add good protein
- Maple syrup: Skip the fake stuff and get pure maple syrup for the real deal flavor
- Dijon mustard: Brings a zingy kick that works magic with the maple sweetness
- Apple cider vinegar: Just a touch wakes up all the other flavors
- Garlic powder: Gives a nice background flavor without taking over
- Cheese: Totally up to you, but sharp cheddar really makes it pop
Step-by-Step Instructions
- Make the maple mustard sauce:
- Mix up maple syrup, Dijon mustard, apple cider vinegar, garlic powder, black pepper, and salt in a bowl. Stir until everything's completely mixed. You want it runny enough to drizzle with a nice golden color. Make a bigger batch to keep in the fridge for your next sandwich craving.
- Prepare the eggs:
- Break eggs into a bowl and add milk, salt, and pepper. Beat them until they're good and foamy for extra fluffiness. Melt some butter in a non-stick pan over medium heat just until it bubbles. Pour in your egg mix, let it sit for half a minute, then gently fold with a soft spatula. Keep folding until they're just set but still look a bit wet and shiny, around 2 minutes total.
- Heat the sausage:
- Warm up your pre-cooked turkey sausage in another pan over medium heat for about 2 minutes on each side until they get a bit crispy on the edges and hot in the middle. If you're using plant-based sausage, follow the box but they usually need about 3 minutes per side.
- Toast the croissants:
- Cut croissants in half using a bread knife. Put them cut-side down in a dry pan over medium-low heat until they turn golden, about a minute. Keep an eye on them since all that butter means they can burn fast.
- Assemble your masterpiece:
- Put the bottom halves of your toasted croissants on plates. Share the eggs evenly between them. Put a sausage patty on each. Pour plenty of your maple mustard sauce on top, about a spoonful per sandwich. Add some cheese if you want. Top with the other half of the croissant and eat right away while everything's warm.

That maple mustard combo is what makes this sandwich stand out. I stumbled on it while playing around with some leftover ham glaze and wow - what a game-changer! The slight kick from the Dijon cuts through the buttery croissant perfectly.
Make-Ahead Options
When you know tomorrow's gonna be crazy, get everything ready tonight. Cook your eggs, let them cool, and keep them in the fridge in a sealed container - just warm them up for 30 seconds in the microwave. The sauce keeps for a whole week in the fridge in a little jar. Just put it all together right before you want to eat for the best results.
Smart Substitutions
This sandwich works with all kinds of tweaks based on what you like or need. Swap the turkey sausage for bacon, Canadian bacon, or veggie sausage. If you can't do dairy, use some olive oil instead of butter, any non-dairy milk, and either skip the cheese or grab a plant-based one. Gluten-free croissants work too, though they're usually a bit heavier.
Serving Suggestions
Make your breakfast extra special by adding some fresh fruit, a small green salad, or some crispy breakfast potatoes on the side. For weekend gatherings, why not set out all the ingredients and let everyone build their own sandwich? Tastes amazing with iced coffee or a mimosa if you're feeling fancy.

Treat yourself to this fancy breakfast sandwich and make any regular morning feel like a special occasion!
Frequently Asked Questions
- → Can I prepare the maple mustard sauce ahead of time?
Absolutely, you can make the maple mustard sauce up to 5 days early and keep it in the fridge in a sealed container. Just remember to give it a quick stir before using since the mixture might separate a bit during storage.
- → What can I substitute for turkey sausage?
You've got plenty of choices instead of turkey sausage. Go with traditional pork breakfast sausage, crispy bacon, sliced ham, plant-based sausage patties, or even some avocado slices if you don't want meat. Each choice brings its own unique taste while keeping the sandwich filling and satisfying.
- → Can I make these sandwiches ahead for meal prep?
You can put these sandwiches together beforehand and wrap them tightly in foil or parchment, then stick them in the fridge for up to 2 days. When you're ready to eat, wrap them in foil and warm them at 325°F for about 10-15 minutes. For the best results, keep the sauce in a separate container and add it right before eating.
- → How can I make this dairy-free?
To skip the dairy, grab some plant milk like almond, oat or soy for scrambling the eggs, cook with olive oil instead of butter, and skip the cheese or grab a dairy-free alternative. The maple mustard sauce doesn't have any dairy in it already.
- → What sides pair well with these breakfast sandwiches?
These sandwiches go great with fresh fruit, a light green salad, crispy breakfast potatoes, yogurt with granola, or a small cup of soup if you're having them for lunch. Drink-wise, they're perfect with coffee, tea, or a glass of fresh orange juice to balance the sweet and savory combo.
- → Can I use regular mustard instead of Dijon?
Dijon mustard really gives the perfect tang that works with the maple syrup sweetness, but you can swap it for whole grain mustard if you want similar flavor with more texture, or regular yellow mustard for something milder. You might need to adjust how much you use to get the taste just right.
