The Key Ingredients You’ll Need
Creating a spectacular Cheesy Potato Casserole starts with quality ingredients. Here’s what you’ll need to make the magic happen.
For the Potato Casserole:
- Potatoes: Frozen shredded hash browns are the secret to a quick prep time. No peeling or shredding required!
- Onion: Finely chopped onion adds a subtle, savory base layer of flavor.
- Sour Cream: This adds a tangy richness that balances the cheese and creates an ultra-creamy texture.
- Melted Butter: Because everything is better with butter! It adds richness and helps bind the casserole.
- Seasonings: A simple mix of garlic powder, salt, and black pepper is all you need.
For the Homemade Cheese Sauce:
- Butter & Flour: These form a roux, the classic base for thickening our creamy sauce.
- Milk: Use whole milk for the richest, creamiest results.
- Cheddar Cheese: Sharp cheddar cheese provides the best flavor. Freshly grated is a must, as it melts much smoother than pre-shredded varieties.
Step-by-Step Instructions
Making this Cheesy Potato Casserole from scratch is easier than you think. Follow these simple steps for a perfect bake every time.
- Preheat and Prep: Start by preheating your oven to 350°F (175°C) and lightly greasing a 9×13-inch baking dish.
- Combine Casserole Ingredients: In a large bowl, combine the thawed hash browns, chopped onion, sour cream, melted butter, garlic powder, salt, and pepper. Mix until everything is evenly coated.
- Make the Cheese Sauce: In a medium saucepan, melt the butter for the sauce over medium heat. Whisk in the flour and cook for one minute to form a roux. Gradually pour in the milk, whisking constantly to prevent lumps. Cook, stirring, until the sauce thickens.
- Add the Cheese: Remove the saucepan from the heat and stir in the shredded cheddar cheese until it’s completely melted and the sauce is smooth.
- Combine and Bake: Pour the cheese sauce over the potato mixture and stir gently to combine. Spread the mixture evenly into your prepared baking dish. Bake for 45-55 minutes, or until the casserole is bubbly and the top is golden brown.
Let the casserole rest for a few minutes before serving. This allows it to set up, making it easier to serve. If you’re looking for another comforting classic, our Beef and Macaroni Soup is a perfect winter warmer.
Tips for the Perfect Casserole
Want to ensure your Cheesy Potato Casserole is flawless? Here are some expert tips to guide you.
- Thaw Your Hash Browns: For the best texture, make sure your frozen hash browns are completely thawed and drained of any excess water.
- Grate Your Own Cheese: Pre-shredded cheeses are often coated in anti-caking agents that can make your sauce gritty. Grating your own ensures a silky-smooth melt.
- Don’t Overbake: Bake just until the center is hot and the edges are bubbly. Overbaking can cause the sauce to separate and become oily.
- Let It Rest: Allowing the casserole to sit for 10-15 minutes after baking helps it firm up for perfect, clean slices. It will still be plenty hot!
Variations and Add-Ins
One of the best things about this Cheesy Potato Casserole is its versatility. Feel free to get creative and make it your own!
- Add Protein: Stir in cooked, crumbled bacon, diced ham, or shredded chicken to make it a complete meal.
- Sneak in Veggies: Steamed broccoli florets or sautéed mushrooms are excellent additions.
- Spice It Up: Add a pinch of cayenne pepper or a dash of hot sauce to the cheese sauce for a little kick. For a different kind of kick, you could even try adding some of the flavors from our Calabrian Chili Pasta.
- Crunchy Topping: For extra texture, top the casserole with crushed cornflakes, panko breadcrumbs, or crispy fried onions during the last 15 minutes of baking.
What to Serve with Your Casserole

The key is to use quality ingredients and not to overbake. Using freshly grated, full-fat cheese ensures a smooth melt without the oiliness that can come from some processed cheeses.
