Ingredients List
For the Beef Layer:
- 1.5 pounds lean ground beef (93/7 lean-to-fat ratio recommended)
- 1 large yellow onion, diced (sweet onions work beautifully as substitute)
- 3 cloves fresh garlic, minced (or 1 teaspoon garlic powder)
- 2 tablespoons tomato paste for depth
- 1 teaspoon smoked paprika
- 1 teaspoon dried oregano
- ½ teaspoon ground cumin
- Salt and freshly cracked black pepper to taste
For the Potato Layer:
- 3 pounds Yukon Gold potatoes, thinly sliced (Russets work if you prefer fluffier texture)
- 2 cups low-sodium beef broth
- 1 cup whole milk (2% milk acceptable)
- 3 tablespoons all-purpose flour
- 2 tablespoons butter
For the Cheese Topping:
- 2 cups sharp cheddar cheese, freshly grated
- ½ cup Parmesan cheese, grated
- 2 tablespoons fresh chives, chopped (dried chives work in pinch)
Timing
This Ground Beef and Potatoes Casserole requires 25 minutes of active preparation time and 65 minutes of baking time, totaling 90 minutes – which is actually 20% faster than most traditional casserole recipes. The beauty lies in the hands-off baking period, allowing you to prepare side dishes or simply relax. For optimal results, plan for an additional 10-minute resting period after baking, bringing your total timeline to approximately 100 minutes from start to finish.
Step 1: Prepare Your Potatoes and Preheat
Begin by preheating your oven to 375°F (190°C) and generously buttering a 9×13-inch baking dish. Wash and peel your potatoes, then slice them into ⅛-inch thick rounds using a mandoline slicer or sharp knife. Pro tip: Consistent thickness ensures even cooking – aim for slices thin enough to read through but thick enough to maintain structure.
Step 2: Create the Savory Beef Base
Heat a large skillet over medium-high heat and add the ground beef, breaking it apart with a wooden spoon. Cook for 6-8 minutes until browned and no pink remains. Add diced onions and cook for 3 minutes until softened. Stir in minced garlic, tomato paste, and all seasonings, cooking for another 2 minutes until fragrant. Chef’s secret: Don’t drain the beef fat if using lean meat – those rendered juices add incredible flavor.
Step 3: Build Your Creamy Sauce Foundation
In a medium saucepan, melt butter over medium heat and whisk in flour, cooking for 1 minute to eliminate raw flour taste. Gradually pour in beef broth while whisking constantly to prevent lumps. Add milk and continue whisking until the mixture thickens slightly, about 3-4 minutes. Season with salt and pepper.
Step 4: Layer Like a Pro
Arrange half of your sliced potatoes in overlapping rows across the bottom of your prepared baking dish. Pour half of the cream sauce over the potatoes, then spread the seasoned beef mixture evenly on top. Layer the remaining potatoes over the beef, then pour the remaining sauce over everything, ensuring it seeps between the layers.
Step 5: The Perfect Bake
Cover tightly with aluminum foil and bake for 45 minutes. Remove the foil and sprinkle both cheeses evenly over the top. Return to the oven for an additional 20 minutes until the cheese is golden brown and the potatoes are fork-tender. Temperature check: The internal temperature should reach 165°F for food safety.

Family-friendly tip: Let kids customize their portions with toppings like diced avocado, cherry tomatoes, or a dollop of sour cream. This casserole also shines as a make-ahead option for potluck dinners or meal prep Sundays.
Common Mistakes to Avoid
Slicing potatoes too thick is the number one error that leads to undercooked centers – stick to ⅛-inch thickness for even cooking. Skipping the flour in your sauce results in separated, watery layers instead of creamy cohesion. Overcrowding the beef while browning creates steam rather than the desired caramelized flavor – cook in batches if necessary. Finally, rushing the resting period after baking prevents the layers from setting properly, leading to a messy serving presentation.
Storing Tips for the Recipe
This Ground Beef and Potatoes Casserole stores beautifully in the refrigerator for up to 4 days when covered tightly with plastic wrap or aluminum foil. For optimal reheating, cover with foil and warm in a 350°F oven for 15-20 minutes, or use microwave in 90-second intervals. Freezer-friendly option: Assemble the entire casserole without baking, wrap securely, and freeze for up to 3 months. Thaw overnight in the refrigerator before baking, adding an extra 10 minutes to the cooking time.
FAQs
Can I make this casserole ahead of time?
Absolutely! Assemble the entire dish up to 24 hours in advance, cover, and refrigerate. Add 10-15 minutes to the baking time if cooking straight from the refrigerator.
What’s the best way to achieve evenly cooked potatoes?
Use a mandoline slicer for consistent ⅛-inch thickness, and ensure your sauce has enough liquid to create steam during the covered baking phase.
Can I substitute the ground beef with other proteins?
Ground turkey, chicken, or even plant-based alternatives work wonderfully. Adjust cooking times accordingly – poultry should reach 165°F internal temperature.
Why is my casserole watery?
This usually occurs from skipping the flour in the sauce or using potatoes with high water content. Always include the flour thickener and consider salting potato slices for 15 minutes, then patting dry before assembly.
How do I know when the casserole is fully cooked?
The top should be golden brown, the edges should be bubbling, and a knife should easily pierce through all potato layers without resistance.
