Step 1

Caramelize the onions: Heat the olive oil over medium-low heat in a large heavy pan. Add the onions and cook, stirring occasionally, for about 30 minutes until they are a deep, rich, golden brown.

Step 2

Ham and Spinach: Toss the ham in a skillet with a drizzle of olive oil. Pan-fry until browned and some fat is rendered. Add spinach and stir to wilt.

Step 3

Whisk eggs with the milk, dijon, salt, and pepper.

Step 4

Preheat the oven to 350°F. Grease a 9×13 baking dish. Layer the ham, spinach, and onions on the bottom. Sprinkle with half of the cheese. Pour eggs over. Arrange croissant pieces on top. Finish with remaining cheese.

Step 5

Cover with foil and bake for 30 minutes. Remove foil and bake for another 5-10 minutes until the middle is almost firm when given a jiggle test. Let rest for a few minutes before serving.
