The Soft Scramble Sandwich

Preparation

1. Step 1

   Place a rack in center of oven; preheat to 350°. Trim woody ends of spring onions. Separate white bulbs from green parts with a knife. Cut bulbs in half through the root end; if size varies wildly, cut larger bulbs into quarters. Cut tender green parts of stalks into 3" pieces; set aside separately from bulbs.

   Step 2

   Heat 2 Tbsp. butter in a 10" nonstick skillet over medium until foaming. Add onion bulbs and toss to coat in butter; season with salt and pepper. Cook, stirring often, until deeply golden brown and starting to soften, 4–5 minutes. Add vinegar, onion stalks, and ½ cup water and continue to cook, stirring occasionally, until almost all liquid is cooked off and bulbs are very soft and jammy, 6–8 minutes longer. Transfer to a plate. Wipe out skillet.

   Step 3

   While onions cook, mix ricotta and Parmesan in a small bowl; season with salt and pepper. Finely grate lemon zest and garlic into ricotta mixture and stir to combine.

   Step 4

   Warm focaccia in oven (place directly on rack) until soft and warmed through but not browned, 2–3 minutes. Divide between plates. Spread ricotta mixture in swooshing dollops on top of focaccia.

   Step 5

   Melt remaining 1 Tbsp. butter in skillet over medium-low heat. Add eggs; season with salt. Cook, stirring frequently in large sweeping figure-eight motions with a spatula, until eggs have set into creamy folds, 1–2 minutes.

   Step 6

   Divide scrambled eggs between focaccia. Top with onion mixture.
