What are the basics of a good casserole?

For me, a good casserole starts with a balance of textures and flavors. I like to combine something crispy, like hash browns or a breadcrumb topping, with creamy eggs or sauce and a savory protein like bacon or sausage. Even seasoning throughout each layer makes a huge difference, and taking the time to sauté vegetables adds depth you can really taste.

How long can I keep a breakfast casserole in the fridge?

I usually store leftover casserole in an airtight container for up to 3–4 days. When reheating, I prefer the oven or toaster oven to keep the edges slightly crisp—microwaving works too, but it can make the center a bit soft.

What to prepare for a Christmas brunch?

From my experience, a Christmas brunch should have a mix of sweet and savory dishes. I love pairing this Christmas Brunch Casserole with something simple like fresh fruit, a light salad, or a sweet treat like my Christmas Crack Recipe . It keeps the meal balanced and festive.

Instructions

Gather all ingredients.

Cook bacon in a large skillet over medium-high heat, turning occasionally, until evenly browned, about 10 minutes. Transfer bacon to a paper towel-lined plate and crumble when cool enough to handle. Drain grease from the skillet.

Cook onions and mushrooms in the residual grease in the skillet until onions are translucent and mushrooms are tender, about 5 minutes.

Grease a 9×13-inch casserole dish with 1 tablespoon of butter. Place potatoes into the bottom of the dish; sprinkle with salt, pepper, and garlic salt. Top with crumbled bacon, then add onions and mushrooms.

Whisk milk, eggs, and parsley together in a mixing bowl; pour over casserole and top with Cheddar. Cover and refrigerate, 8 hours to overnight.

When ready to bake, preheat the oven to 400 degrees F (200 degrees C). Bake in the preheated oven until set, about 1 hour.

Serve hot and enjoy!
