Breakfast casserole

I have to bring a breakfast-type food to an event coming up.  I've made this breakfast casserole before and it turns out great.  Here's the recipe:

16-1/4inch baguette slices, cut on diagonal
1 tbsp. butter
12 oz. fresh baby spinach leaves
1 lb. sweet Italian sausage
1-1/2 cups Fontina cheese, shredded
3/4 cup diced drained roasted red peppers
6 large eggs
1 cup heavy cream
1 cup whole milk
1 tsp salt
1/4 tsp black pepper

Preheat oven to 350.  Butter an 8x8x2 baking dish.  Place 8 baguette slices in bottom; press 2 baguette slices onto each side.  Melt 1 tbsp butter in large pot over medium heat.  Add spinach; toss until wilted (about 3 min.)  Transfer spinach to strainer; cool.  Squeeze dry.  Transfer to medium bowl.

Heat same pot over medium-high heat.  Add sausage; break up and saute until cooked through.  Mix into spinach; mix in 1 cup cheese and peppers.  Spread atop baguette slices in bottom of dish.  Whisk eggs in medium bowl to blend.
Whisk in last 4 ingredients.  Pour over spinach mixture and stir lightly with fork to distribute.  Sprinkle remaining 1/4 cup cheese over top.  Bake until puffed, golden and set - about 55 min.  Remove from oven and allow to rest for about 15 min.

I'll post a picture when I actually put it together.
