This one sounds similar but serves 20 so you may need to reduce it:
BUFFET BREAKFAST CASSEROLE (serves 20)
1 large loaf day-old French bread, torn into pieces
6 TBL melted butter
1/2 lb chopped ham
3/4 lb shredded Swiss cheese
1/2 lb shredded Monterey Jack
16 eggs
3 cups milk
3/4 cup dry white wine
4 green onions, thinly sliced
1/2 tsp cayenne
1 1/2 TBL Dijon mustard
1 1/2 cups sour cream
3/4 cup Parmesan

Grease two 13x9x2" casserole dishes. Spread bread pieces in each pan & drizzle with butter. Sprinkle with ham, Swiss & Monterey Jack cheeses.
Mix eggs, milk, wine, green onions, mustard & pepper & beat until foamy. Pour half over each casserole & refrigerate several hours or overnight.
Remove from refrigerator 30 minutes before baking. Preheat oven to 325°, cover & bake 1 hour.
Remove from oven, spread with sour cream & sprinkle tops with Parmesan. Bake uncovered for an additional 10 minutes or until lightly browned.~~Tide & Thyme

This one will work with stale French Bread also & can be halved:
OVERNIGHT FRENCH TOAST (serves 15)
16 oz cream cheese, cubed
12 eggs, beaten
2 cups milk
1/3 cup maple syrup
1 1/2 tsp cinnamon
8 slices white bread, crusts removed, cubed

Combine cream cheese, eggs, milk, maple syrup & cinnamon in a bowl & mix well. Add the bread & mix gently. Spoon into a 9x13
baking pan. chill, covered for 8-10 hours. Bake, uncovered in a preheated 375° oven for 40 minutes. Sere with additional maple syrup.~~Texas Ties

Thank you. I am going to make one each of the Creme Brulee and the Buffett breakfast casserole because I couldn't decide between the two.

Thanks again for your time.

I hope you enjoy them! Happy Holidays, Magic.

You're most welcome.
