Instructions

Preheat oven to 350°F (175°C). Lightly toast the croissant cubes on a baking sheet for 5 minutes. Set aside.
Whisk the custard: In a large bowl, whisk together eggs, milk, Dijon mustard, nutmeg, salt, black pepper, and cayenne. Set aside.
Prepare spinach: Heat 1 tbsp oil/butter in a skillet over medium heat. Sauté shallot until soft. Add spinach, season with salt and pepper, and cook for 2-3 minutes. Remove from heat.
Assemble strata: Grease a 9x13-inch baking dish. Layer half of the croissants, followed by half the spinach, Gruyere, and feta. Pour half of the custard over. Repeat the layers. Press down gently.
Chill: Cover with foil and refrigerate for at least 2 hours or overnight.
Bake: Let the strata sit at room temperature for 30 minutes. Bake covered for 30 minutes, then uncover and bake for 20-30 more minutes until set and golden brown.
Rest & Serve: Let rest for 5 minutes before serving.

Notes

Make-Ahead: Prep the night before and bake fresh in the morning.
