Recipe Overview
Prep Time: 10 minutes
Cook Time: 10 minutes
Total Time: 20 minutes
Servings: 2 sandwiches

Ingredients
- 4 large eggs
- 1 tablespoon butter
- 2 brioche buns, lightly toasted
- 2 slices cheddar cheese
- 2 tablespoons caramelized onions (optional)
- 1 tablespoon mayonnaise or aioli (optional)
- Salt and pepper, to taste
- Fresh chives or parsley, for garnish
Step-by-Step Instructions
1. Prepare the caramelized onions (optional)
In a small skillet, cook sliced onions in butter over low heat for 10–15 minutes, stirring occasionally until golden and soft.
2. Make the soft scrambled eggs
Crack eggs into a bowl and whisk until well combined. Melt butter in a nonstick skillet over low heat. Pour in eggs and stir continuously until just set and creamy. Season with salt and pepper.
3. Assemble the sandwich
Spread mayonnaise or aioli on the bottom of each toasted brioche bun. Add a slice of cheddar cheese, pile on the creamy scrambled eggs, and top with caramelized onions.
4. Serve and enjoy
Top with the other half of the bun and serve immediately while warm. For extra indulgence, add crispy bacon or a sausage patty.

Pro Tips & FAQs
How do I make my eggs super creamy?
Cook the eggs low and slow, stirring constantly. Remove from heat just before fully set — they’ll continue cooking off the heat.
Can I use a different cheese?
Yes! American, Havarti, or Swiss cheese melt beautifully in this recipe.
What makes this sandwich unique?
The contrast of buttery eggs, sweet onions, and a soft brioche bun sets this apart from any standard breakfast sandwich.
