Don't know that it's the best but this is the one I like:
COMPANY BRUNCH (serves 8)
5 sourdough English muffins, split (or regular ones)
1 cup shredded Cheddar
1 cup shredded Swiss cheese
1 lb breakfast sausage, cooked, drained, crumbled (or crisp bacon or chopped ham)
12 eggs, lightly beaten
2 cups milk
1/3 cup chopped parsley
1/3 cup chopped green onions with tops
1 cup sliced fresh mushrooms
Arrange the muffins in a buttered 9x13" baking dish. Sprinkle with the Cheddar & Swiss cheese & sausage. Beat the eggs, milk, parsley & green onions in a bowl until mixed. Pour over the prepared layers. Chill, covered with foil for 8-10 hours. Sprinkle w/the mushrooms. Bake in a preheated 350 oven for 50 minutes or until set. Let stand 10 minutes before serving.~~From Texas Ties

I cant find the recipe I had but someone here I believe gave it to me....It was done with Texas toast and eggs with cheese...maybe someone can help this was delicious and I myself would love to have it again!

I used this one for my son's college graduation and it was a big hit:
12 slices bread
3c cubed ham
3c cubed cheddar cheese
6 eggs
2 1/2c milk
S&P to taste
dash of dry mustard
Grease bottom of 9x13" pan. Lay 6 slices
bread in pan. Add ham and cheese. Cover
with remaining bread. Mix and beat all remaining
ingredients together. Pour over all. Cover with foil
and refrigerate overnight. Bake at 350° for 50-60 minutes.
May add 2c broccoli flowerettes & 1 c sautéed mushrooms.

HAM & CHEESE BREAD PUDDING

I may have posted this here already, but if not here it is again. You can serve with assorted breads, rolls, and fresh fruit, and it can be made a day in advance.

Butter for greasing the baking pans

1/2 c. melted butter
1 loaf of stale French bread cut into cubes
1 pound grated Swiss cheese
1/2 pound of cooked, chopped ham
1 bunch green onions, thinly sliced
16 large fresh eggs
3 & 1/2 cups of milk or half & half
1/2 c. dry white wine
1 good T. Dijon mustard
Cayenne & white pepper to taste
1 cup sour cream
1 cup grated parmesan cheese

Butter (2) 9X13 inch baking dishes

Divide the bread between the dishes.
Drizzle the bread with the melted butter, then sprinkle in the Swiss cheese, ham, and sliced green onions.

Whisk together the eggs, milk, mustard and wine, and season with the cayenne & white pepper.

Pour the egg mixture over the bread mixture, and be sure each piece is saturated well with the liquid.

Cover the dishes and place in the fridge overnight or up to 24 hours.

Remove the dishes from the fridge at least 30 minutes before baking, and PREHEAT the oven to 325 degrees.

Bake, covered for about one hour, then uncover and spread each dish with 1/2 half cup of sour cream. then sprinkle each with 1/2 cup of the parmesan cheese.

Return to the oven and bake for about 10-15 minutes or until golden browned.

Allow to cool a bit before serving.

This recipe can be halved, but the two dishes will serve 25.

I am always asked for this recipe. It works very well for breakfast or brunch.

This is last minute so I guess it doesn't quite qualify as a casserole - but its good anyway :-) Following are some others that I like a lot.

APPLE PUFFED PANCAKE

6 eggs
1-1/2 cups milk
1 cup flour
3 tablespoons granulated sugar
1 teaspoon vanilla extract
1/2 teaspoon salt
1/4 teaspoon cinnamon
1/4 lb. butter
2 apples, peeled, cored and thinly sliced
3 tablespoons brown sugar

Preheat oven to 425 degrees.

In blender (or large bowl) mix eggs, milk, flour, granulated sugar, vanilla, salt and cinnamon until blended. (If using a mixer, batter will remain slightly lumpy.) Melt butter in a 12 inch quiche dish or a 13 x 9 glass dish in the oven. Add the apple slices to the dish and return to the oven until the butter sizzles. Do not let brown. Remove the dish from the oven and immediately pour the batter over the apples. Sprinkle with brown sugar. Bake in the middle of the oven 20 minutes or until puffed and brown. Serve immediately.

6-8 servings.

½ cup Parmesan cheese

SAUSAGE CAKE WITH EGGS

For a variation, make the recipe above and after you put the mixture into a cake pan, make as many indentations in the mixture as you want, and then put an egg into each indentation. Also you can sprinkle the egg/mixture with shredded cheese. Then cook as specified above. This makes for an easy breakfast or brunch.
