Savory Croissant Casserole with Mushroom, Spinach and Cheese

Leftover Croissants…?

Yes, this could happen! In fact, it has been happening to me a lot lately, as I’ve working on developing three different versions (1-day, 2-day and 3-day) of my Classic French Croissant recipes.

So I have been left with dozens of croissants on the counter, and even though I am very much fond of them, going through 36 in a day became a bit too much. And you’ll probably agree that days-old croissants simply do not have the same oomph as freshly baked ones.

So I have been thinking of ways to use up my leftovers croissants, and making a savory croissant casserole is the first thing that came to my mind. I wanted a comforting dish to cut through the bitter Winter evenings. I imagined the textures and flavours I wanted, and worked backwards from there…

A great Winter dinner or crowd-pleasing brunch

The croissants paired with mushrooms provides the perfect mix of sweet and salty flavors. The bittery spinach cut nicely through the richness of the croissants.

The tender baked eggs and cheese perfectly compliment the crisp edges of the croissants. With leftover croissants on hand, it is a quick and easy dish to put together (less than 15 minutes), and makes for a great Winter dinner or crowd-pleasing brunch. Cooking notes:

• Using fresh spinach is best for this dish (they render less water); but if you have to use frozen spinach, make sure your thaw and drain them very well, and cook them all the way through until no moisture is left in the pan.
• Gruyère cheese is great in this dish, but feel free to use any hard cheese of your liking. 1 cup (100g) is a fair amount of cheese – just enough to bring comfort and flavour, but not overkill (remember croissants are already rich to start with). Feel free to use more/less cheese, to suit your taste.
