How to make hash brown casserole
Be sure to thaw your hash browns in the fridge overnight before you make this dish.
No one wants to bite into a frozen hash brown, and thawing them first allows for more even and quick cook time.
First, add your garlic and onion to a skillet with a drizzle of olive oil, and cook until soft. This will help avoid crunchy onions in the finished dish, while still giving the casserole a great depth of flavor!
In a large bowl, add your hash browns, cream of mushroom soup, cooked onion and garlic, sour cream, melted butter, salt, pepper, and one cup of freshly grated sharp cheddar.
Freshly grated cheese ALWAYS tastes better, so please don’t skip this step.
The flavor is worth the extra few minutes grating a block of sharp cheddar.
Once mixed together, transfer the hash brown casserole to a baking dish.
Top with the remaining sharp cheddar cheese.
Bake at 375 for 40 minutes or so, until nice and browned and bubbly.
Kids and adults alike will love this recipe!
Perfect for a family breakfast, potluck, or any special occasion!
