Full Ingredients
For the fluffy scrambled eggs
- 4 large eggs
- 2 tablespoons whole milk
- 1/4 teaspoon kosher salt
- 1/8 teaspoon black pepper
- 1 tablespoon unsalted butter
For the panini
- 2 ciabatta rolls, split (about 6–7 inches each), or 4 slices sourdough bread (1/2-inch thick)
- 4 tablespoons basil pesto (2 tablespoons per sandwich)
- 6 ounces fresh mozzarella, sliced into 1/4-inch rounds
- 1 tablespoon olive oil or 1 tablespoon softened unsalted butter (for brushing the bread)
Optional for serving
- 1 cup baby arugula (tossed with a pinch of salt and a drizzle of olive oil)
- Fresh basil leaves (for garnish)
Step-by-Step Instructions
Step 1: Preheat your press (or skillet) for maximum crispness
Preheat a panini press to 375°F. If using a skillet or griddle, preheat it over medium-low heat until the surface is about 325°F (if you have an infrared thermometer) or until it feels evenly hot when you hover your hand a few inches above the surface.
Gentle heat gives the bread time to crisp while the mozzarella melts fully.
Step 2: Whisk the eggs for tender, airy curds
In a medium bowl, whisk together 4 large eggs, 2 tablespoons whole milk, 1/4 teaspoon kosher salt, and 1/8 teaspoon black pepper until the mixture looks uniform and slightly frothy (about 20–30 seconds).
Step 3: Soft-scramble the eggs (don’t overcook)
Set a nonstick skillet over medium-low heat. Add 1 tablespoon unsalted butter and let it melt completely without browning.
Pour in the egg mixture. Using a silicone spatula, stir slowly and continuously, scraping the bottom and sweeping the eggs into soft folds. Cook until the eggs are just set but still a little glossy, 3–4 minutes.
Immediately remove the eggs from the heat (they’ll keep cooking from residual warmth). This is the key to fluffy eggs inside the sandwich.
Step 4: Build the sandwiches in the right order for even melting
Lay out the bread, cut-side up. Spread 2 tablespoons pesto on the inside of each sandwich (use it on both cut faces if you like maximum pesto flavor).
On the bottom piece of each sandwich, layer about half the fresh mozzarella. Spoon the scrambled eggs evenly over the mozzarella, then top with the remaining mozzarella. Close the sandwiches.
Putting cheese on both sides helps the sandwich “glue” together and melt evenly.
Step 5: Lightly oil the outside for a golden, crisp crust
Brush the outside of each sandwich with a thin, even layer of 1 tablespoon olive oil (total) or spread a thin layer of softened butter. This promotes browning and keeps the crust shatter-crisp.
Step 6: Press and grill until crisp outside and gooey inside
Panini press method: Place the sandwiches in the preheated press (375°F). Close and press gently. Cook until the bread is deeply golden with clear grill marks and the mozzarella is melted, 5–7 minutes.
Skillet method: Place the sandwiches in the skillet over medium-low. Set a heavy pan or a foil-wrapped brick on top to press. Cook 3–4 minutes, flip carefully, re-weight, and cook another 3–4 minutes, until crisp and the cheese is fully melted.
Step 7: Rest, slice, and serve like a café
Transfer the panini to a cutting board and rest for 1 minute (this helps the cheese set slightly so it doesn’t all run out). Slice in half on the diagonal and serve immediately.
If you’re serving with arugula, toss it with a tiny pinch of salt and a drizzle of olive oil, then plate alongside.
Pro Tips
- Keep the eggs slightly underdone. They finish cooking from the sandwich heat, staying soft instead of dry.
- Use low heat for the press/skillet if your bread browns too fast. Aim for a slow, even toast so the mozzarella melts completely.
- Fresh mozzarella releases moisture. If it seems very wet, pat slices dry with paper towels to help the bread stay crisp.
- Don’t overstuff. A moderate layer of eggs and cheese presses better and heats through more evenly.
- Clean cuts. Let the sandwich rest 1 minute before slicing for neat layers.
Variations
- Tomato Caprese breakfast panini: Add 4 thin slices ripe tomato (pat dry) and a few basil leaves inside; grill as directed.
- Spicy pesto panini: Stir 1/2 teaspoon Calabrian chili paste or a pinch of red pepper flakes into the pesto before spreading.
- Extra-hearty panini: Add 2 ounces thinly sliced cooked ham or turkey per sandwich (warm it briefly in the pan before assembling).
Storage & Make-Ahead
Best fresh: This panini is at its peak right off the press, when the bread is crisp and the mozzarella is stretchy.
Make-ahead components: You can slice the mozzarella and portion the pesto up to 2 days ahead and refrigerate. For fastest mornings, set out the bread, pesto, and cheese while you scramble the eggs.
Short hold: If making two sandwiches back-to-back, keep the first panini warm on a sheet pan in a 200°F oven for up to 15 minutes.
Leftovers: Wrap and refrigerate up to 2 days. Reheat on a skillet over medium-low (about 300°F surface temp) for 3–4 minutes per side with a weight on top, or bake on a sheet pan at 350°F for 10–12 minutes until hot throughout.
