The Cast of Characters: Ingredients You’ll Need

Before you start, let’s gather the simple ingredients that make this dish so special. Each component plays a crucial role in creating the perfect balance of flavors.

  • Potatoes: Yukon Gold or Russet potatoes work best. They hold their shape well but become wonderfully tender.
  • Ground Beef: Lean ground beef (85/15 or 90/10) is ideal to avoid excess grease.
  • Onion and Garlic: These aromatics build the foundational flavor of the beef mixture.
  • Cheese: A sharp cheddar cheese provides a bold, tangy flavor that cuts through the richness. We’ll also use some mozzarella for that irresistible cheese pull.
  • For the Sauce: Butter, all-purpose flour, milk, and sour cream create a luxuriously smooth and creamy cheese sauce.
  • Seasonings: Salt, black pepper, and a touch of smoked paprika are all you need.

How to Make Cheesy Beef and Potato Casserole: A Step-by-Step Guide

Follow these simple steps to create a flawless layered potato and ground beef casserole. We’ll break it down so you can easily follow along.

Step 1: Prepare the Potatoes

First, peel and thinly slice your potatoes, about 1/8-inch thick. A mandoline slicer is great for this, but a sharp knife works too. Place the sliced potatoes in a large bowl of cold water to prevent them from browning while you prepare the other components.

Step 2: Cook the Beef Mixture

In a large skillet, cook the ground beef over medium-high heat until browned. Break it apart with a spoon as it cooks. Add the chopped onion and cook until softened, about 5 minutes. Stir in the minced garlic and cook for another minute until fragrant. Drain off any excess fat and season with salt and pepper.

Step 3: Make the Creamy Cheese Sauce

In a saucepan, melt the butter over medium heat. Whisk in the flour and cook for one minute to create a roux. Gradually whisk in the milk until the mixture is smooth. Let it simmer, stirring often, until it thickens. Remove from the heat and stir in the sour cream, smoked paprika, and half of the shredded cheddar and mozzarella cheese. Stir until the cheese is completely melted and the sauce is velvety smooth.

Step 4: Assemble the Casserole

Preheat your oven to 375°F (190°C). Drain the potatoes thoroughly and pat them dry. In a 9×13 inch baking dish, start layering. Begin with a thin layer of the cheese sauce on the bottom. Add a layer of sliced potatoes, overlapping them slightly. Top with half of the ground beef mixture. Pour about one-third of the cheese sauce over the beef. Repeat the layers: potatoes, the remaining beef, and another third of the sauce. Finish with a final layer of potatoes and pour the rest of the cheese sauce evenly over the top.

Step 5: Bake to Golden Perfection

Cover the baking dish with foil and bake for 45 minutes. Remove the foil, sprinkle the remaining shredded cheddar and mozzarella cheese on top, and bake for another 15-20 minutes, or until the potatoes are tender and the top is bubbly and golden brown. Let the casserole rest for 10 minutes before serving. This allows it to set, making it easier to slice.

Pro Tips for Casserole Success

Want to make your Cheesy Beef and Potato Casserole truly unforgettable? Here are a few expert tips:

  • Don’t Slice Potatoes Too Thickly: For perfectly cooked, tender potatoes, ensure your slices are thin and uniform.
  • Shred Your Own Cheese: Pre-shredded cheese often contains anti-caking agents that can make your sauce gritty. Shredding a block of cheese will result in a much smoother melt.
  • Let It Rest: This is crucial! Letting the casserole sit for at least 10 minutes after baking helps it firm up for perfect slices.

Delicious Variations to Try

Feel free to customize this recipe! Try adding a layer of steamed broccoli for extra nutrients, or mix in some corn with the beef. For a spicy kick, add a pinch of red pepper flakes to the cheese sauce. You can even swap the ground beef for ground turkey or chicken.

What to Serve with Your Casserole

This hearty casserole is a meal in itself, but it pairs wonderfully with a few simple sides. For a classic comfort dinner, serve it alongside some delicious fluffy honey cornbread to sop up the extra sauce. A simple green salad or a side of honey-roasted carrots can also add a nice, fresh contrast to the richness of the dish. For another comforting side, you can’t go wrong with our Gouda mashed potatoes.

Storage and Reheating Instructions

This Cheesy Beef and Potato Casserole is a fantastic make-ahead meal. You can assemble it completely, cover, and refrigerate for up to 24 hours before baking. If you have leftovers, store them in an airtight container in the refrigerator for up to 3 days. To reheat, simply bake in the oven at 350°F until warmed through, or microwave individual portions.

Frequently Asked Questions

Absolutely! You can assemble the entire casserole, cover it tightly with foil, and refrigerate it for up to 24 hours. When you’re ready to eat, just bake it as directed, adding about 10-15 minutes to the initial covered baking time.

For best results, bake the casserole first and allow it to cool completely. Cover it tightly with a layer of plastic wrap and then a layer of aluminum foil. It can be frozen for up to 3 months. Thaw overnight in the refrigerator before reheating in the oven.

To prevent a watery casserole, ensure you drain the potatoes well and pat them dry after soaking. Also, using a leaner ground beef (like 90/10) and draining any excess fat after cooking will significantly reduce excess liquid.

This dish pairs well with simple sides like a crisp green salad, steamed green beans, roasted broccoli, or fluffy cornbread to balance the richness of the casserole.

Yukon Gold or Russet potatoes are the best choices. Yukon Golds are slightly waxy and hold their shape well, while Russets are starchy and become very tender, absorbing the flavors of the sauce beautifully.

For the best results, shred your own cheese from a block. It melts much more smoothly than pre-shredded varieties.
Ensure your potato slices are thin and uniform for even cooking.
Letting the casserole rest before slicing is essential to allow it to set properly.
