Many say breakfast is the most important meal of the day. With this casserole, it’s also the most delicious!
We are big fans of breakfast and we are big fans of casseroles, so, we were determined to come up with the best of both worlds. You could use homemade hash browns, but, we find that thawed frozen hash browns do the trick, and make preparing the dish so much easier. Perfect for serving a hungry gathering, especially during the holiday season!

The Ingredients You Will Need
The ingredients in this casserole can be tweaked to suit your family’s tastes. Feel free to change up the veggies! Spice it up with jalapeños, if desired. For our version, here’s what you’ll need to have on hand:
Cooking Spray – Our softened butter, for greasing a 9×13″ baking dish.
Pork breakfast sausage – We like ‘hot’ breakfast sausage, but regular is delicious (and has no spice to it).
Onion – Chopped.
Bell pepper – Seeded and chopped. Our preference is red, but you go with your favorite. Green, yellow, red, or a combination. Or, just leave it out!
Green chilis – Canned. These can be found in the Hispanic section of most well-stocked supermarkets.
Eggs – You’ll need 12 of them. This feeds a hungry household!
Half and half – Whole milk can be substituted for the half and half.
Seasonings – Salt, pepper, garlic powder.
Frozen hash browns – Thawed. This can be easily done by defrosting in your microwave.
Shredded cheese – Cheddar, Monterey Jack, and Colby are all great options, or a combination of them!
Scallions – Thinly sliced, for garnish. Optional
EXPERT TIP: Simply add the peppers and onion into the skillet along with the uncooked sausage and then cook until the sausage is no longer pink. The sausage will render some grease during the cooking process which perfectly sautés the vegetables. If there is excess grease, tilt the skillet to the side and spoon it out.
Tips for Making the Best Breakfast Casserole
Cook the Sausage with the Veggies – Brown the breakfast sausage with your favorite vegetables before adding it to the casserole. This infuses the vegetables with the sausage flavor and allows you to spoon out excess rendered grease before adding to the egg and cream mixture.
Use Frozen Hash Browns – Opt for frozen hash browns for convenience and texture. They provide a crispy base when baked and save you the hassle of grating fresh potatoes. Just make sure to thaw them slightly and toss them with salt and pepper before adding to the dish.
Layer Ingredients – For an even distribution of flavors, layer the ingredients in the casserole dish. Start with a layer of hash browns, followed by the egg and sausage mixture, and then the cheese on the top. This ensures that every bite is flavorful and well-balanced.
Let it Rest – Allow the assembled casserole to rest for at least 15-30 minutes before baking. This resting period helps the flavors meld together and allows the hash browns to absorb some of the egg mixture, resulting in a more cohesive and delicious dish.
EXPERT TIP: You’ll need to let the cooked sausage and vegetables mixture cool somewhat before adding to the eggs and cream mixture. If you add them while they are still very hot, it will start to cook the eggs, which will lead to uneven baking.
How To Serve
As mentioned, this is a large casserole and can easily feed 8 to 10 people, depending on how hungry they are and what else you are serving.
Leftovers are delicious and heat up nicely. However, if you prefer, you can cut the recipe in half for a smaller serving.
We love to serve this during the holidays for a nice brunch and include maple pepper bacon and homemade monkey bread.
EXPERT TIP: Take care when pouring the egg and sausage mixture over the hash browns. Use a wooden spatula or spoon to help distribute the mixture evenly over the potatoes. Top with the cheese and then press the cheese into the egg mixture gently with clean hands.
