Hash Brown Breakfast Casserole
Are you a protein-for-breakfast type of person? I totally am. In fact, I usually have leftovers of some kind in the morning, like Chicken Parmesan or Crispy Sheet Pan Gnocchi, instead of the typical oatmeal or toast. I love having a little extra something in my belly before getting on with my day.
So when I test a breakfast casserole like this one, it’s perfect. I eat it morning, noon, or night, and I even send it with Mike for lunches.
THIS casserole is a simple layering of 1) hash browns, 2) a sausage and veggie sauté, followed by an egg, milk, and cheese combo. It bakes up in 35’ish minutes or so and is thick and filling. Make sure you have a deep 9×9 dish to bake it in, or use a larger one and watch your baking time. Using a larger dish will result in a thinner casserole, thus less time required to bake it.
Why This Recipe Works:
- SIMPLE – This easy breakfast casserole recipe uses simple ingredients and can be ready to eat in an hour or so.
- FILLING – There is plenty of protein in each serving of this hashbrown casserole. It will fill you up for hours!
- DELICIOUS – What could be better than a combo of sausage, hash browns, eggs, and cheese? This breakfast bake is normally a complete meal for me with a side of fruit.
- HOLIDAY BREAKFAST – Make this sausage hash brown casserole for Christmas Breakfast, Easter brunch, or any special occasion.
Ingredients Used:
You can easily find these simple ingredients in your local grocery store.
- Sausage – I prefer a spicy turkey sausage, but you could use regular pork sausage (mild or sweet) or chicken sausage.
- Veggies – Onions, jalapeño pepper, bell pepper, and garlic.
- Seasonings – Kosher salt, freshly ground black pepper, and ground mustard.
- Shredded Hashbrowns – Use frozen hash browns. I like the southwest version (i.e. spicy).
- Eggs – Use about 8 large eggs.
- Milk – I normally use 2% milk, but whole milk or any version works.
- Cheese – Any cheese you prefer. I went with a Mexican Cheese. You could also use sharp cheddar cheese or pepper jack cheese for cheesy goodness.
How to make Sausage-Hashbrown Breakfast Casserole:
Step 1
Sauté sausage and veggies. In a cast iron skillet over medium-high heat, add sausage, veggies, salt, and pepper. Cook until the sausage is fully cooked and the veggies are softened. Remove mixture to a separate bowl.
Step 2
Combine egg mixture. In a separate bowl, whip the eggs, milk, half of the cheese, and a little bit more salt and pepper.
Step 3
Assemble. In a 9×9 casserole dish, layer the thawed hash browns, the sausage and veggies, and then the egg mixture. Top with the remaining cheese.
NOTE: When I originally tested this casserole, I sautéed the hash browns before layering them. But in the end, it’s just way easier to let them thaw out and skip the pre-cook.
Step 4
Bake. Bake the casserole, uncovered, for about 30 minutes. If it’s still jiggly in the center of the casserole, bake for a few more minutes.
Step 5
Serve breakfast casserole. Serve casserole with some sliced avocado and one or more of the following.
- Chunky Guacamole
- Easy Pico de Gallo
- Jalapeno Ranch Dressing
- Grilled Salsa
- A dash of hot sauce or sriracha!
How to Store and Freeze:
- Store leftover sausage breakfast casserole in an airtight container. This easy recipe makes great meal prep too.
- Freeze leftover casserole in a freezer-safe container for up to three months.
What to serve with this breakfast casserole:
Let’s be honest. Some extra carbs are definitely a great pairing to eggs and sausage. Here are some favorite recipes for you!
- Fresh fruit is always a great choice. Or make our Peanut Butter Coffee Smoothie, Orange Julius Smoothies, or Cherry Smoothies.
- MUFFINS – Strawberry Rhubarb Muffins, The Best Blueberry Muffins, and Moist Banana Muffins
- BREAD– Multi-Grain Seeded Bread, Whole Wheat Honey Bread, and The Best Cinnamon Rolls
- BISCUITS – Best Homemade Buttermilk Biscuits and Homemade Jalapeno Cheddar Biscuits
Recipe FAQs:
Yes, you can make up the entire casserole, cover with plastic wrap and refrigerate in advance, even the day before.
Leftovers are good for up to four days.
Feel free to use a different type of sausage (or bacon or ham) and different vegetables (like mushrooms or spinach).
You can use a larger casserole dish, but since it will be thinner, it will take less time to bake.
Yes, this is fairly healthy with a great balance of protein, carbs, and vegetables. I used a turkey sausage but any works.

Sausage Hash Brown Breakfast Casserole
Ingredients
- 1 pound turkey sausage – use any type of sausage you prefer
- 1 medium onion – diced
- 1 medium jalapeno – diced (with or without seeds)
- 1 medium bell pepper – diced, any color (or a variety)
- 3 cloves garlic – minced
- 16 oz. hash browns – thawed (if frozen)
- 8 large eggs
- 1/4 cup milk
- 6 oz. Mexican cheese
- kosher salt and freshly ground black pepper – to taste
- 1 teaspoon ground mustard
Instructions
- In a cast iron skillet over medium-high heat, add Italian sausage, onion, jalapeno, bell pepper, and salt & pepper. Saute until sausage is cooked through and veggies are softened. Add garlic at the very end and cook for another minute. Remove mixture to a separate bowl.
- In a separate bowl, combine the eggs, milk, the ground mustard, a little more salt and pepper, and half of the cheese. Whisk.
- Prepare a 9×9 pan with baking spray. Layer the hashbrowns, then the cooked sausage and veggie mixture, followed by the egg mixture. Top with the remaining half of cheese.
- Bake the casserole, uncovered, in a preheated 375 degree oven for 30-35 minutes. If it's getting too brown on top, cover with foil for part of the baking time.
- Let the casserole sit for 5-7 minutes, and then serve!
Notes
- This is a thick casserole, so if you don’t have a deep 9×9 casserole dish, use a slightly larger one. Reduce the baking time accordingly.
- Leftovers are good for up to four days.
