Step‑by‑Step Instructions for Hashbrown Breakfast Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While it heats, take a 9×13 inch baking dish and generously grease it with butter or cooking spray to prevent sticking. This will ensure your Hashbrown Breakfast Casserole bakes evenly and can be easily served once done.
Step 2: Prepare the Hash Brown Base
In a large mixing bowl, combine the thawed shredded hash browns with melted butter, 1 cup of shredded cheddar cheese, salt, and black pepper. Use a spatula to thoroughly mix these ingredients until well combined. Press the hash brown mixture firmly into the bottom of the greased baking dish to create an even base that will hold all the delicious layers above.
Step 3: Cook the Sausage & Vegetables
Heat a skillet over medium heat and add your breakfast sausage. Cook, breaking it apart with a spatula until browned and fully cooked, which should take about 5-7 minutes. Once crumbled, add in the chopped onion and green bell pepper, cooking until softened and fragrant. Remove the skillet from heat and set aside to cool slightly before layering.
Step 4: Whisk the Eggs
In a large mixing bowl, crack the large eggs and pour in the milk. Whisk together until smooth and well-blended, ensuring there are no streaks of egg white. Season the mixture with a pinch of salt and black pepper to taste. This egg mixture will create a rich custard-like base for your Hashbrown Breakfast Casserole.
Step 5: Layer the Ingredients
Once the hash brown base is properly pressed into the baking dish, evenly distribute the cooked sausage and vegetable mixture over the top. Make sure to spread everything out for balanced flavor. Next, pour the egg mixture over the entire casserole, ensuring everything is saturated. Finally, sprinkle the remaining shredded cheddar cheese evenly on top.
Step 6: Bake the Casserole
Place the prepared dish into the preheated oven and bake for 45-55 minutes. Keep an eye on it during the last 10 minutes; you want the casserole to be golden brown and set in the center. If the top is browning too quickly, tent it with aluminum foil to prevent burning while the inside continues to cook.
Step 7: Cool & Serve
Once baked to perfection, remove the Hashbrown Breakfast Casserole from the oven and allow it to cool for about 10-15 minutes. This resting time helps the casserole set and makes slicing easier. After it’s cooled, cut into squares and serve warm, getting everyone excited for a hearty breakfast treat.

Hashbrown Breakfast Casserole Recipe FAQs
How do I select the best hashbrowns for this casserole?
Absolutely! For the best results, I recommend using frozen shredded hash browns that are completely thawed before use. Look for bags that contain only potatoes without added preservatives or seasonings. Avoid any with dark spots or excess moisture—this will keep your casserole from becoming soggy.
What is the best way to store leftovers?
After enjoying your delicious Hashbrown Breakfast Casserole, store any leftovers in an airtight container in the refrigerator. They can stay fresh for up to 3-4 days! When reheating, just pop it in the microwave—though I suggest using the oven for about 20 minutes at 350°F (175°C) to keep that crispy texture intact.
Can I freeze the casserole?
Yes! To freeze your Hashbrown Breakfast Casserole, I recommend cutting it into individual portions first. Wrap each piece tightly in plastic wrap, then slide them into a freezer-safe bag. This will keep them fresh for up to 3 months. When you’re ready to enjoy, just take out a portion and thaw it in the refrigerator overnight before reheating.
What if my casserole doesn’t set properly while baking?
If your Hashbrown Breakfast Casserole doesn’t set in the center, no worries! Simply continue baking it for an additional 5-10 minutes, checking it every couple of minutes to avoid over-browning. Insert a knife in the center—if it comes out clean, your casserole is good to go! If not, give it a bit more time.
What dietary considerations should I be aware of?
Great question! If you’re serving guests with dietary restrictions, this Hashbrown Breakfast Casserole can easily adapt. Use turkey sausage or skip the meat entirely for a vegetarian version, and replace the milk with unsweetened almond or oat milk for dairy-free options. Just ensure all your additives like sauces and breads are gluten-free if necessary!
Can I prepare this casserole ahead of time?
Absolutely! One of the beauties of this Hashbrown Breakfast Casserole is that you can prepare it the night before. Simply assemble all the ingredients, cover it with foil, and refrigerate.
