<\/div>\n\t\t<\/p>\n This post may contain affiliate links, see my\u00a0disclosure policy<\/a>\u00a0for details.<\/span><\/p>\n<\/div>\n This Hashbrown Breakfast Casserole recipe is perfect for holiday breakfasts or brunches or just an easy and fun family breakfast. Packed with all your favorites, it\u2019s exceptionally easy to make and comes together in no time. You can even prep it the night ahead and just put it in the oven when you\u2019re ready!<\/p>\n If you know me, you know I\u2019m all about a good shortcut\u2014especially when it leads to something that feels a little extra special without a lot of effort. For this Sausage, Egg, and Hashbrown Casserole, I tested and tweaked the recipe to keep it fast, flexible, and foolproof. One of my favorite tricks? Using already shredded hash brown potatoes. It saves a ton of prep time in the kitchen and guarantees the potatoes cook up nice and tender by the time the casserole is ready. <\/p>\n As a busy mom juggling real life and real meals, I designed this recipe to work with your schedule\u2014make it the night before, pop it in the oven the next morning, and enjoy a hearty breakfast that feels just right for weekends, holidays, or any morning you want to make a little more special.<\/p>\n If you\u2019re looking for another overnight casserole for a special occasion, try my brioche French toast casserole<\/a>! It\u2019s perfect for any Sunday bake or holiday breakfast.<\/p>\n This simple breakfast recipe only needs basic ingredients to make. Ingredients are also customizable to your tastes \u2013 I\u2019ve included some swaps below and in the substitutions section!<\/p>\n This is an abbreviated step-by-step overview of the recipe card instructions. Refer to directions at the bottom of the post for full instructions, including temps and times.<\/p>\n Step 1<\/strong><\/p>\n Preheat the oven and grease a 13\u00d79-inch baking dish with cooking spray or butter.<\/p>\n Cook the sausage in a large skillet over medium heat for a few minutes until it begins to release its fat.<\/p>\n After the sausage has partially cooked, add diced onion and bell peppers and saut\u00e9 until softened and the sausage is cooked through. Stir in garlic, cook for another 30 seconds, remove from heat, and set aside.<\/p>\n Step 2<\/strong><\/p>\n In a blender (or food processor, or bowl with an immersion blender<\/a>) add the eggs, cottage cheese, milk, salt, and pepper, and blend until smooth.<\/p>\n Note:<\/strong> If the cottage cheese curds are really tiny or if you don\u2019t mind the curds, you can skip the blending step and just whisk the ingredients together.<\/p>\n Step 3<\/strong><\/p>\n Layer the casserole: <\/p>\n Spread the hashbrowns evenly in the greased baking dish.<\/p>\n<\/div>\n Add the cooked sausage and veggies in a layer over the hashbrowns.<\/p>\n<\/div>\n<\/div>\n Sprinkle 1 cup of the cheddar cheese across the veggies.<\/p>\n<\/div>\n Then pour the egg mixture evenly over everything.<\/p>\n<\/div>\n<\/div>\n Sprinkle the remaining cheddar cheese on top.\u00a0<\/p>\n Step 4<\/strong><\/p>\n Bake uncovered for 40-50 minutes, or until the eggs are set in the center and the top is golden brown. (Internal temp should be 170\u00b0F on a meat thermometer)<\/p>\n Recipe Note:<\/strong> If the casserole is baked, but the top needs more browning, turn on the broiler to high and broil for just 1-2 minutes until golden brown.<\/p>\n Let the casserole rest for 10 minutes before slicing. Serve warm.<\/p>\n For an easy make ahead breakfast casserole, assemble the casserole completely, except for the last layer of cheese. Cover and store the casserole dish in the fridge overnight. Before baking, top with cheese and bake as instructed, uncovered.\u00a0<\/p>\n Keep leftovers in the fridge up to 4 days. Reheat in the microwave or on a piece of parchment paper in the air fryer at 300\u00b0F until warmed through.\u00a0<\/p>\n This casserole freezes really well. Wrap individual slices in plastic wrap or store portions in freezer-safe containers, and freeze for up to 3 months. You can thaw before reheating, or just pop a slice straight into the microwave\u2014heat for 1\u20132 minutes, or until warmed through.<\/p>\n Yes. Frozen shredded hashbrowns need to be thawed, drained, and patted dry before adding to the casserole.\u00a0<\/p>\n<\/p><\/div>\n Yes. The casserole can be assembled the night before and baked off the next day.<\/p>\n<\/p><\/div>\n I do not, the layer of cheese on top protects the eggs from drying out. The addition of the cottage cheese and milk also adds extra moisture to keep the casserole from getting dry.<\/p>\n<\/p><\/div>\n<\/p><\/div>\n <\/p>\n Just enter your email below and we will send this recipe right to your inbox, plus we will send more yummy recipes and ideas.<\/p>\n <\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n Preheat the oven to 375\u00b0F. Grease a 13\u00d79-inch baking dish with cooking spray or butter.<\/p>\n<\/li>\n Cook the sausage in a large skillet over medium heat until it begins to release its fat (about 5 minutes). If you\u2019re using a lean sausage like turkey or chicken, coat the frying pan with 1-2 tablespoons of oil before cooking.<\/p>\n<\/li>\n After the sausage has partially cooked, add the diced onion and red pepper and saut\u00e9 until softened and the sausage is cooked through, around 7-8 more minutes. Stir in the minced garlic and cook for another 30 seconds. Remove from the heat.<\/p>\n<\/li>\n In a blender, food processor, or a deep bowl with an immersion blender, add the eggs, milk, cottage cheese, salt, and pepper. Blend until smooth. Note:<\/strong> If the curds are tiny enough or you don’t mind the texture, you can skip the blending and just whisk the eggs, milk, and cottage cheese together in a bowl.<\/span><\/p>\n<\/li>\n To layer the casserole, spread the hashbrowns evenly in the baking dish. Next, add the cooked sausage and veggies in an even layer over the hashbrowns.<\/span><\/p>\n<\/li>\n Sprinkle 1 cup of cheddar cheese across the veggies. Then pour the egg mixture evenly over everything and sprinkle the remaining 1 cup of cheddar cheese on top.<\/p>\n<\/li>\n Bake the casserole uncovered for 40\u201350 minutes until the eggs are set in the center (170\u2109 on an instant read thermometer) and the top is golden. Tip:<\/strong> If the casserole is done, but the cheese hasn’t browned, broil on high for 1-2 minutes until golden and bubbly. Watch it closely so it doesn’t burn.<\/span><\/p>\n<\/li>\n Remove from the oven and let the casserole rest for 10 minutes before slicing. Serve warm.<\/span><\/p>\n<\/li>\n<\/ul>\n<\/div>\n<\/div>\n![\"A](\"https:\/\/barefootinthepines.com\/wp-content\/uploads\/2025\/11\/Hashbrown-Breakfast-Casserole-4.jpg\"\/)
