This maple mustard croissant breakfast sandwich transforms ordinary mornings into something extraordinary. The combination of buttery croissants, fluffy eggs, and a sweet-tangy maple mustard sauce creates a restaurant-quality breakfast you can enjoy in your pajamas.

I created this recipe during a lazy Sunday morning when I wanted something special without leaving home. My family now requests these sandwiches for weekend brunches and even special occasions.

Ingredients

  • Croissants: Fresh bakery croissants provide the perfect buttery base with delicate layers
  • Large eggs: Choose free-range eggs for richer yellow yolks and better flavor
  • Milk: Adds creaminess to the eggs; use whole milk for extra richness
  • Turkey sausage patties: Pre-cooked for convenience, adds hearty protein
  • Maple syrup: Use real maple syrup, not pancake syrup, for authentic flavor
  • Dijon mustard: Adds tangy complexity that balances the sweet maple
  • Apple cider vinegar: Brightens all flavors with subtle acidity
  • Garlic powder: Adds savory depth without overpowering
  • Cheese: Optional but recommended; use sharp cheddar for best flavor

Step-by-Step Instructions

Make the maple mustard sauce:
Combine maple syrup, Dijon mustard, apple cider vinegar, garlic powder, black pepper, and salt in a small bowl. Whisk thoroughly until completely blended. The sauce should have a pourable consistency with a beautiful amber color. Make extra to keep in the refrigerator for future sandwiches.
Prepare the eggs:
Crack eggs into a medium bowl and add milk, salt, and pepper. Whisk vigorously until frothy for fluffier eggs. Melt butter in a nonstick skillet over medium heat until it starts to bubble but not brown. Pour in egg mixture and let it set for 30 seconds before gently folding with a silicone spatula. Continue folding until eggs are just set but still glossy and moist, about 2 minutes.
Heat the sausage:
Warm pre-cooked turkey sausage patties in a separate skillet over medium heat for 2 minutes per side until edges are slightly crispy and center is hot. For plant-based sausage, follow package instructions but typically cook 3 minutes per side.
Toast the croissants:
Slice croissants horizontally with a serrated knife. Place cut-side down in a dry skillet over medium-low heat until golden brown, about 1 minute. Watch carefully as croissants can burn quickly due to their high butter content.
Assemble your masterpiece:
Place toasted croissant bottoms on plates. Divide scrambled eggs evenly among croissants. Top with sausage patties. Drizzle generously with maple mustard sauce, approximately 1 tablespoon per sandwich. Sprinkle with cheese, if using. Cap with croissant tops and serve immediately while still warm.

The maple mustard sauce is truly the star of this recipe. I discovered this combination when experimenting with leftover glazed ham and never looked back. The slight tang from the Dijon cuts through the richness of the croissant, creating perfect balance.

Make-Ahead Options

For busy mornings, prepare components the night before. Store scrambled eggs in an airtight container, refrigerate, and gently reheat in the microwave for 30 seconds. The maple mustard sauce can be made up to one week ahead and stored in a jar in the refrigerator. Assemble just before serving for the freshest results.

Smart Substitutions

This recipe welcomes adaptations based on dietary needs and preferences. Replace turkey sausage with bacon, Canadian bacon, or vegetarian sausage. For dairy-free versions, use olive oil instead of butter, plant-based milk, and skip the cheese or use dairy-free alternatives. Gluten-free croissants work wonderfully though they tend to be slightly denser.

Serving Suggestions

Elevate your breakfast spread by serving these sandwiches alongside fresh fruit, a light arugula salad, or crispy breakfast potatoes. For special brunches, create a sandwich bar with the components laid out, allowing guests to build their own. Pair with cold brew coffee or a mimosa for weekend indulgence.

Frequently Asked Questions

→ Can I prepare the maple mustard sauce ahead of time?

Yes, the maple mustard sauce can be prepared up to 5 days in advance and stored in an airtight container in the refrigerator. Just give it a good stir before using, as the ingredients may separate slightly when stored.

→ What can I substitute for turkey sausage?

You have several options to substitute turkey sausage. Try regular pork breakfast sausage, bacon, ham, vegetarian sausage patties, or even avocado slices for a meat-free option. Each alternative will provide a different flavor profile while maintaining the sandwich's heartiness.

→ Can I make these sandwiches ahead for meal prep?

These sandwiches can be assembled ahead of time and wrapped tightly in foil or parchment paper, then refrigerated for up to 2 days. To reheat, wrap in foil and warm in a 325°F oven for 10-15 minutes. For best texture, consider storing the sauce separately and adding it just before serving.

→ How can I make this dairy-free?

To make this dairy-free, use plant-based milk (like almond, oat, or soy) for the scrambled eggs, use olive oil instead of butter for cooking, and either omit the cheese or use a dairy-free cheese alternative. The maple mustard sauce is already dairy-free.

→ What sides pair well with these breakfast sandwiches?

These sandwiches pair beautifully with fresh fruit, a simple green salad, breakfast potatoes or hash browns, yogurt parfaits, or a cup of soup if serving for lunch. For beverages, consider coffee, tea, or fresh orange juice to complement the sweet and savory flavors.

→ Can I use regular mustard instead of Dijon?

While Dijon mustard provides the ideal tangy flavor that balances the sweetness of the maple syrup, you can substitute with whole grain mustard for a similar effect with more texture, or yellow mustard for a milder flavor profile. You may want to adjust quantities to taste.
