Cheesy Hash Brown and Egg Breakfast Casserole

I love that this is a one pan meal. It goes from the stove straight into the oven. If you don't have an oven safe pan, you can use a regular skillet and transfer your hash browns to a baking dish. This breakfast casserole is a great choice if you have company over for breakfast. Enjoy it with sour cream, hot sauce, or ketchup (ofcourse) ;).

Instructions

    Cup of Yum
  1. Pre-heat oven to 350F. Heat your skillet over medium heat. Melt in 1 Tbsp butter then add chopped onion and saute until golden. Remove onion to a plate. Add sliced mushrooms to the hot skillet and saute until golden and soft. Remove to the same plate as the onions.
  2. In the same pan over medium heat, melt 1 Tbsp butter with 1 Tbsp olive oil. Layer the hash browns evenly into the bottom of the pan and sauté until golden on the bottom (about 7 minutes total). Flip hash browns over a few times while sautéing. Once they are golden brown and nearly cooked through, remove from heat. Note: If you are baking in a casserole dish, transfer your potatoes to that dish and set aside.
  3. In a large bowl, whisk together 6 large eggs, 1/4 cup sour cream, 1/2 tsp seasoning along with about 1/2 tsp salt and 1/8 tsp pepper. Whisk together until well combined then stir in sautéed onion and mushrooms. Stir in sliced ham and 1/2 cup cheese just until combined.
  4. Pour the egg mixture evenly over the hashbrowns and top with remaining 1/2 cup shredded cheese. Cover loosely with foil and Bake at 350˚F for 25 minutes then remove foil and Bake another 5-7 minutes or until cheese is bubbly and starting to brown. Garnish with halved baby tomatoes and fresh cilantro or sliced green onions.
