Cheesy Hash Brown Casserole comes straight from the 100 Days of Real Food book. It is a mixture of two of my favorite things…. potatoes and cheddar cheese!
This is super-simple to make, especially if you use frozen hashbrowns. And trust me, buy the frozen. I tried with homemade hash browns one time and it just didn’t work very well. I couldn’t get all of the moisture out of the potatoes and it was a runny mess.
Cheesy Hash Brown Casserole is a great option if you need a recipe for a pot-luck style brunch. I made it for my Mothers of Preschoolers meeting on month and everyone was asking me for the recipe.
Step by Step
Preheat the oven to 350F and grease a square baking dish.
In a large skillet, melt the butter over medium heat then cook the diced onion for about 2-3 minutes, just until it softens. Add the minced garlic and cook for another minute.
Turn the heat down to medium-low and slowly whisk in the flour while stirring continuously.
Whisk in the milk, salt, and pepper and stir until it thickens in the flour, about 2-3 minutes.
Remove the pan from the heat and add the shredded cheddar cheese. Stir continuously until the cheese has all melted.
Fold the hash browns into the cheese mixture. If your pan is big enough, you can do it in the pan. I prefer to mix it all in a large mixing bowl to make sure I have the space needed.
Transfer the mixture to the greased baking dish and smooth it out as much as possible.
Bake the casserole for about 30-35 minutes, uncovered. The cheese should start to bubble but probably won’t be brown.
If you want to brown the cheese, you can turn the broiler on for a few minutes.
