Perfect Slow-Cooked Strata (Egg Casserole)

2 ish cups of “add-ins” – I used a pound of sliced mushrooms and a big handful of parsley. basically just sauté and season whatever veggie or meat you have until it tastes delicious.
6 large eggs
1/4 cup creamy milk or milk substitute heavy cream or whole milk or almond milk or cashew yogurt!
your preferred spices/seasonings
1 cup cheese in this one I used cheddar, parm, and a few leftover bits of brie!
2 cups cubed bread I like brioche

Sauté the ”add-ins” (veggies and/or meat) in an ovenproof 10-inch skillet until caramelized and delicious. Let the skillet cool for a few minutes. Beat together the eggs and cream and seasonings. Fold in a cup of whatever the cheese you have, plus the 2 cups of cubed bread. Pour egg mixture into the skillet and stir to combine. Best if refrigerated overnight but you can bake it right away if you must. Bake at 250f for 30 to 40 minutes, until JUST cooked through but still a tad wet looking. Let it cool and firm up for a few minutes, then slice and enjoy. I like to serve mine with arugula tossed with salt, pepper, lemon juice and evoo. Reheats PERFECTLY in the microwave for about 30 seconds.
