Step-by-Step Cooking Instructions

Follow these easy steps to bring your Sausage Hashbrown Casserole to life:

1. Preheat and Prep

Preheat your oven to 350°F (175°C). Grease your baking dish with butter or non-stick spray.

2. Cook the Sausage

In a skillet over medium heat, brown the sausage until fully cooked and no longer pink. Drain excess grease and set aside to cool slightly.

3. Mix the Base

In a large bowl, combine the thawed hashbrowns, cooked sausage, chopped onions, and 1 ½ cups of shredded cheese. Toss gently to mix.

4. Add the Egg Mixture

In a separate bowl, whisk together the eggs, milk, garlic powder, salt, and pepper. Pour this over the hashbrown mixture and stir to combine evenly.

5. Assemble and Top

Pour the entire mixture into the greased baking dish. Smooth the top and sprinkle the remaining ½ cup of cheese over it.

6. Bake

Bake uncovered for 40–45 minutes or until the center is set and the top is golden and bubbly. Let rest for 5–10 minutes before slicing and serving.

Common Mistakes to Avoid

Here are a few tips to make sure your bake comes out perfect every time:

Don’t skip thawing: Frozen hashbrowns can water down the mixture and affect baking time.
Check doneness: The center should be set and not jiggly. A knife inserted should come out clean.
Avoid dry casserole: Cover with foil if the top is browning too fast.
Let it rest: Always allow to cool slightly after baking for clean slices and best texture.

FAQs About Sausage Hashbrown Casserole

Can I make it without eggs?

Yes, but it changes the texture. Consider using a plant-based egg substitute or increase the cream and cheese content for binding.

How long does it last in the fridge?

Up to 4 days when stored in an airtight container.

Can I use fresh potatoes instead of frozen hashbrowns?

Absolutely! Just shred, rinse, and dry them thoroughly to prevent sogginess.

What cheeses work best?

Cheddar is classic, but you can also try:

Colby Jack
Swiss
Gruyère
Sharp white cheddar for a bolder flavor
