When you take that first bite of a Croissant Breakfast Sandwich, your taste buds dance with joy. The outer layer breaks with a light snap, then you'll sink into its soft, airy middle packed with gooey cheese, tasty meat slices, and cloud-like scrambled eggs – all brought together by a sweet and tangy honey-mustard mix that'll make your morning.

Key Ingredients and Shopping Advice

  • Croissants: Go for ones made with real butter that feel almost weightless and show clear layers when you look at them.
  • Cheese: Pick something that melts nicely, like Havarti, Gruyère, or Gouda for best results.
  • Eggs: Don't skimp here – farm-fresh or pasture-raised eggs will really boost the flavor.
  • Dijon Mustard: Grab a smooth, premium Dijon to get that perfect zip in your spread.

Step-by-Step Cooking Guide

Step 1:
Mix your flavor base by warming 2 tbsp butter, 2 tbsp Dijon mustard, and 2 tbsp honey in the microwave until soft enough to blend. Stir until it's all combined.
Step 2:
Cut your croissants sideways, trying to keep one side attached like a hinge.
Step 3:
Spread the honey-mustard butter mix on the inside of each croissant half.
Step 4:
Stack cheese, your choice of ham or bacon, then another cheese slice inside each croissant.
Step 5:
Put them face-open in a 350°F (175°C) oven for 10-15 minutes until the cheese gets bubbly and the edges turn crispy.
Step 6:
While they're baking, mix 5 large eggs with 2 tbsp milk and a bit of salt and pepper.
Step 7:
Cook your egg mix on medium-low, gently pushing the edges toward the center until they're just set but still look moist.
Step 8:
Put your soft scrambled eggs on the bottom half of each croissant, sprinkle with fresh herbs if you want, and close them up.
Step 9:
Eat right away or save them for later.

Warming Up Make-Ahead Sandwiches

For sandwiches you've kept in the fridge, warm them in a 325°F (165°C) oven for 8-10 minutes. If they're frozen, use a 300°F (150°C) oven for about 20 minutes. Want them super crispy? Toss them in an air fryer at 320°F (160°C) – 3-4 minutes for chilled ones or 7-8 minutes if frozen.

Tasty Seasonal Twists to Try

Switch things up with what's growing now – try adding some quick-blanched asparagus in spring, fresh sliced tomatoes in summer, thin apple slices with sharp cheddar in fall, or buttery mushrooms cooked with thyme in winter.

I can't get enough of these Croissant Breakfast Sandwiches because they show how simple ingredients can turn into something amazing with a bit of care and creativity.

Frequently Asked Questions

→ What kind of croissants should I use?
Go for medium or large all-butter croissants. Bakery-fresh ones are ideal for the best taste and crispness, but sturdy store-bought ones work great too. Mini ones are just too small to hold everything.
→ Can I make this meat-free?
Of course! Skip the bacon and ham, and load up on options like avocado slices, roasted peppers, sautéed mushrooms, or spinach. You can even try a veggie sausage patty. The honey-dijon butter and cheese still bring tons of flavor.
→ How do I keep the croissants from burning in the oven?
If the tops start browning too quickly and the insides aren't ready, lightly tent them with foil. This prevents burning while everything else gets warmed through. Check every few minutes to avoid overbaking.
→ What’s the best way to reheat these sandwiches?
Reheat in a 325°F oven wrapped in foil for 10-15 minutes, or use an air fryer at 300°F for about 5-8 minutes. Microwaving works, but it can make the croissants soggy—toast them after microwaving if needed to bring back some crunch.
→ Can I swap out the honey-dijon butter for something else?
Definitely! Try garlic butter, pesto, flavored cream cheese, or even an herbed spread. Each one will give your sandwiches a fun twist while still pairing wonderfully with the fillings.

Ingredients

→ Spread Ingredients

01 2 tbsp honey
02 2 tbsp dijon mustard
03 2 tbsp salted butter

→ Sandwich Components

04 4 large croissants
05 Half a pound of thinly sliced ham
06 8 slices of your favorite cheese (cheddar, gouda, swiss, etc.)
07 8 crispy bacon slices

→ Egg Mixture

08 5 big eggs
09 A dash of milk
10 Salt and pepper to taste
11 1 tbsp butter
12 Optional: fresh chopped chives for garnish

Instructions

Step 01

Set your oven to 350°F (175°C) and let it heat up.

Step 02

Grab a small bowl that's safe for the microwave and toss in the mustard, honey, and butter. Heat for 20 seconds or so until the butter's melted, then stir until smooth.

Step 03

Take a serrated knife to your croissants and slice them in half horizontally. Spread the mustard-honey mix on the cut-side surfaces of both top and bottom halves.

Step 04

Start with the bottom croissant half. Lay down a slice of cheese, then a quarter of the ham, add two bacon slices, and finish with another slice of cheese on top. Put the other croissant half on to finish.

Step 05

Place the prepared sandwiches on a baking tray and bake for 10-15 minutes, or until the cheese has melted and the croissants have a nice golden crust.

Step 06

While the sandwiches are baking, whisk together the eggs, milk, and a pinch of salt and pepper in a bowl.

Step 07

Melt butter in a nonstick pan over medium heat. Pour in your whisked eggs and gently stir to make soft scrambled eggs. Cook for 2-3 minutes until they're just set but still a bit creamy.

Step 08

Take the sandwiches out of the oven, open them up, and divide the scrambled eggs between them. Sprinkle on some chives if you like, then serve.

Notes

  1. Treat yourself to croissant sandwiches loaded with savory ingredients and soft scrambled eggs, perfect for your next brunch.
