Ingredients
 

Main Ingredients

  • 1.5 tbsp olive oil divided
  • 0.5 tbsp unsalted butter
  • 4 cup yellow onions, thinly sliced
  • 0.75 tsp kosher salt
  • 0.5 tsp granulated sugar
  • 1 tsp balsamic vinegar optional
  • 4 cup fresh spinach, chopped
  • 1 tbsp minced garlic
  • 0.25 tsp crushed red pepper flakes
  • 2 tbsp all-purpose flour for dusting
  • 1 lb refrigerated pizza dough
  • 1 tsp Italian seasoning
  • 2 cup low-moisture mozzarella, shredded
  • 0.5 cup grated Parmesan
  • 1 cup marinara sauce for serving

Instructions

Preparation Steps

  • Warm 1 tbsp oil and the butter in a large skillet over medium-low heat.
  • Add onions, salt, and sugar. Cook, stirring often, until deep golden, 22–28 minutes.
  • Splash in balsamic. Stir to deglaze, then scrape onions to a plate to cool slightly.
  • Add remaining 0.5 tbsp oil to the skillet. Sauté garlic and red pepper 30 seconds.
  • Wilt spinach in the pan, 2–3 minutes. Transfer to a bowl and let cool briefly.
  • Heat oven to 400°F. Line a sheet pan with parchment and lightly oil it.
  • Dust counter with flour. Roll dough into a roughly 12x16-inch rectangle.
  • Brush dough lightly with any onion pan juices. Sprinkle evenly with Italian seasoning.
  • Scatter mozzarella over dough. Top with onions, then spinach. Sprinkle Parmesan.
  • Leave a 1-inch bare edge on one long side. Roll up tightly from the opposite side.
  • Pinch seam to seal. Chill the log 10 minutes in the freezer for cleaner slices.
  • Slice into 12 pieces. Arrange cut side up on the prepared pan, spaced slightly.
  • Bake until puffed and golden, 18–22 minutes. Cool 5 minutes on the pan.
  • Warm marinara in a small saucepan. Serve rolls hot with sauce for dipping.

Notes

Swap in crumbled feta for part of the mozzarella, or add a handful of sliced olives. To make ahead, assemble and slice, then refrigerate on a tray up to 12 hours; bake straight from cold, adding 2–3 minutes. Leftovers reheat well at 350°F for 8–10 minutes, or freeze up to 1 month.
