Fancy egg breakfast sandwich with hot sausage & fontina


🌶️ Hot Italian Sausage & Egg Breakfast Sandwich

A savory, spicy, and ultra-satisfying breakfast sandwich layered with caramelized onions, fontina cheese, fluffy eggs, and arugula on a toasted brioche bun—with a creamy kick of sriracha mayo.


🧾 Ingredients

  • 1 white or yellow onion, thinly sliced

  • Olive oil (for sautéing)

  • Salt & pepper, to taste

  • A drizzle of balsamic glaze (optional, but recommended)

  • 1 brioche bun, sliced and toasted

  • 1 hot Italian sausage, casing removed

  • 2 eggs

  • 1 tbsp butter

  • A few slices of fontina cheese

  • A handful of arugula

  • Sriracha

  • Mayonnaise (preferably Kewpie or your favorite brand)


👩‍🍳 Instructions

1. Caramelize the Onions

  • Thinly slice the onion using a mandolin or sharp knife.

  • In a large skillet over medium heat, add olive oil, onions, a pinch of salt, and some cracked pepper.

  • Cook, stirring frequently, until deeply browned and reduced in size—about 20–25 minutes.

  • Optional: Add a drizzle of balsamic glaze during the final few minutes for extra depth of flavor and color.

  • Set aside.

2. Cook the Sausage

  • In the same pan (or a clean one), add the sausage (casing removed).

  • Break it apart with a wooden spoon and cook over medium heat until browned and cooked through, about 5–8 minutes.

  • Transfer sausage to a plate and wipe out the pan with paper towels.

3. Make the Egg Wrap

  • Melt 1 tablespoon of butter in the pan.

  • In a small bowl, whisk the eggs until well combined.

  • Pour into the pan, spreading them into a thin, even layer (like an omelet).

  • While the eggs begin to set, layer the cooked sausage in the center, top with fontina slices, and a scoop of the caramelized onions.

  • Once the eggs are mostly cooked, fold the sides inward to enclose the filling (like a burrito or pocket).

  • Cook for another minute, then remove from heat.

4. Build the Sandwich

  • Toast the brioche bun if you haven’t already.

  • Spread the bottom half with sriracha mayo (mix mayo with sriracha to your taste—Kewpie is especially good).

  • Place the egg wrap on the bun, followed by extra caramelized onions, a small handful of arugula, and the top bun.


🔥 Pro Tips

  • Make ahead: Caramelize a batch of onions in advance—they store well and enhance just about anything.

  • Cheese swap: Not a fan of fontina? Try gouda, provolone, or even sharp cheddar.

  • Spice level: Adjust the sriracha to taste, or use a milder chili sauce if preferred.


🍽️ Final Thoughts

This gourmet breakfast sandwich packs bold flavor, gooey cheese, crispy sausage, and sweet-savory onions into every bite. It’s the kind of brunch-worthy meal that’s just as good for lunch or dinner. Simple, indulgent, and incredibly satisfying.
