Arrange the torn croissants in the dish. Layer the thinly sliced butter over the top before sending it to the oven. Bake for 5-8 minutes until they re lightly toasted and fragrant.
Heat the olive oil in a large skillet over medium heat. When it shimmers, add the mushrooms and season with salt and pepper. Let them cook undisturbed for 5 minutes until golden, then stir for another 3-5 minutes until caramelized. Add the garlic and thyme, cooking for another minute before removing from heat.
Whisk together the cream, milk, eggs, mustard, cayenne, and a pinch of salt and pepper in a large bowl. Introduce the toasted croissants, mushrooms, ham, and Brie cheese, and gently toss everything to combine. Pour the mix back into the casserole dish, evenly topping it with Swiss cheese and sprinkling everything bagel spice if desired.
Cover the dish with foil and bake for 30 minutes. After this, remove the foil and continue baking for another 10-15 minutes until the croissants are golden on top and the dish is bubbly. Serve warm and enjoy the wonderful aroma!
