How to Make Cheesy Potato Breakfast Casserole
Step 1: Preheat the Oven
Preheat your oven to 350°F. While it’s heating, grease your baking dish to prevent sticking.
Step 2: Cook the Sausage and Onion
In a heavy skillet over medium heat, cook the sausage along with the chopped onion. Stir frequently, breaking up the sausage into smaller pieces. Cook until browned throughout, then drain any excess fat and set aside.
Step 3: Combine Ingredients
In a very large bowl, mix together:
1. Thawed hash brown potatoes
2. Lightly beaten eggs
3. Shredded Cheddar cheese
4. Cottage cheese
5. Shredded Swiss cheese
6. Garlic powder
7. Salt
8. Pepper
Stir everything until well combined.
Step 4: Add Sausage Mixture
Add the cooked sausage and onion mixture into your egg mixture. Stir well until all ingredients are evenly distributed.
Step 5: Bake the Casserole
Pour the entire mixture into your prepared baking dish. If you like, cover it tightly with plastic wrap and refrigerate overnight for convenience. Bake in your preheated oven for about 50–60 minutes or until the eggs are set and cheese is melted. If baked from the fridge, you might need to extend baking time slightly. Keep an eye on it; cover with foil if the top begins browning too much.
Let stand for at least 10 minutes before serving so it can set up nicely.

How to Perfect Cheesy Potato Breakfast Casserole

- Cook Sausage Thoroughly: Brown the sausage well before adding it to the mixture to enhance its flavor.
- Don’t Overmix: Gently combine ingredients to keep the texture light and fluffy; overmixing can lead to dense results.
- Check Egg Set: Bake until eggs are just set; this prevents a dry casserole and keeps it moist.
- Let It Rest: Allowing the casserole to sit for at least 10 minutes after baking helps it firm up for easier slicing.

Common Mistakes to Avoid
When making your Cheesy Potato Breakfast Casserole, it’s easy to make some common mistakes. Here are a few to watch out for:
- Not thawing hash browns: Always ensure your frozen hash brown potatoes are completely thawed before mixing. This prevents excess moisture in the casserole.
- Overmixing ingredients: Gently combine the ingredients to maintain a fluffy texture. Overmixing can lead to a dense casserole.
- Skipping the resting time: After baking, let the casserole sit for at least 10 minutes before serving. This helps it set and makes it easier to cut into portions.
- Using low-quality cheese: Opt for high-quality cheeses for the best flavor and meltability. Extra sharp Cheddar enhances the overall taste.
- Not adjusting seasoning: Taste your mixture before baking and adjust salt and pepper as needed. This ensures balanced flavors in your casserole.
