Variations

Swap croissants for English muffins or bagels for a different texture.

Spice it up with a dash of hot sauce in the egg or mustard mix.
Make it cheesy with a blend of cheeses like Swiss, gouda, or pepper jack.

storage/reheating

Wrap leftover sandwiches in foil or plastic wrap and store in the refrigerator for up to 3 days. For longer storage, wrap tightly and freeze for up to one month. Reheat in the oven at 350°F for 10–15 minutes (from fridge) or 20–25 minutes (from frozen) until heated through. You can also microwave for 1–2 minutes, though the croissant may lose its crispiness.

FAQs

How can I make these ahead of time?

You can assemble the sandwiches, wrap them in foil, and refrigerate or freeze them. Reheat in the oven when ready to eat.

Can I use store-bought maple mustard?

Yes, but making your own lets you control the sweetness and tang. It’s simple and worth the extra step.

Are croissants the best bread for this sandwich?

Croissants provide a buttery, flaky texture that complements the savory filling beautifully, but you can use any bread you like.

Can I make these vegetarian?

Absolutely. Skip the meat or use plant-based alternatives. Add veggies like mushrooms or spinach for extra flavor.

What cheese works best?

Cheddar is classic, but Swiss, provolone, gouda, or pepper jack all melt well and taste great.

Can I meal prep these sandwiches?

Yes. Assemble, wrap, and refrigerate or freeze them. Reheat before serving for a quick, delicious breakfast.

Is this sandwich kid-friendly?

Very much so. Kids love the balance of sweet and savory. You can even let them customize their own.

What’s the best way to reheat without drying them out?

Reheating in the oven wrapped in foil keeps the sandwich moist and preserves texture better than the microwave.

Can I add hot sauce?

Yes. Add it to the eggs or drizzle over the sandwich before baking if you like a kick.

Do I need to toast the croissants?

Not necessarily, but a quick bake in the oven crisps them up and melts the cheese perfectly.
