Ingredients
For the Casserole:
2 lbs russet potatoes, peeled and thinly sliced (about 1/8-inch thick)
1 tbsp olive oil
1 large yellow onion, diced
3 cloves garlic, minced
1.5 lbs lean ground beef (90/10)
1 tsp smoked paprika
1 tsp dried thyme
1 tsp salt, divided
½ tsp black pepper
3 tbsp all-purpose flour
2 cups beef broth
1 cup whole milk
1 tbsp Worcestershire sauce
2 cups shredded sharp cheddar cheese, divided
For the Topping:
1 cup shredded Monterey Jack cheese
¼ cup grated Parmesan cheese
Fresh chopped parsley or chives for garnish (optional)
Equipment Needed
9×13 inch baking dish
Large skillet or Dutch oven
Mandoline slicer (optional, but helpful for even potato slices)
Whisk
Step-by-Step Instructions
1. Prep and Par-cook the Potatoes (15 minutes)
Preheat your oven to 375°F (190°C). Lightly grease the 9×13 inch baking dish. Peel the russet potatoes and slice them uniformly thin—a mandoline makes this quick and ensures even cooking. Place the sliced potatoes in the prepared baking dish. Pour in just enough hot water to barely cover them. Cover the dish tightly with foil and bake for 15 minutes. This par-cooking step is crucial for tender potatoes in the final bake. After 15 minutes, carefully drain the water and set the potatoes aside.
2. Brown the Beef & Build the Sauce (15 minutes)
While the potatoes par-cook, heat olive oil in a large skillet or Dutch oven over medium-high heat. Add the diced onion and cook for 3-4 minutes until softened. Add the garlic and cook for another minute until fragrant. Add the ground beef, breaking it up with a wooden spoon. Cook until no pink remains, about 6-8 minutes. Drain any excess fat, if necessary.
Reduce heat to medium. Sprinkle the smoked paprika, thyme, ½ tsp salt, pepper, and flour over the cooked beef. Stir constantly for 1-2 minutes to cook off the raw flour taste.
Slowly pour in the beef broth and milk, whisking continuously to prevent lumps. Add the Worcestershire sauce and remaining ½ tsp salt. Bring the mixture to a gentle simmer, stirring frequently. Let it cook for 3-4 minutes until slightly thickened. Remove from heat and stir in 1 ½ cups of the shredded cheddar cheese until melted and smooth.
3. Assemble the Casserole (5 minutes)
Pour the cheesy beef sauce over the par-cooked potatoes in the baking dish. Gently stir or fold with a spatula to ensure the potatoes are evenly coated and the beef is distributed throughout.
4. Add the Cheese Topping and Bake (35 minutes)
In a small bowl, mix the remaining ½ cup cheddar cheese, Monterey Jack, and Parmesan. Sprinkle this cheese blend evenly over the entire casserole.
Bake, uncovered, in the preheated oven for 30-35 minutes, or until the casserole is bubbling vigorously around the edges and the top is a beautiful, spotty golden brown.
5. Rest and Serve (5 minutes)
This is the hardest but most important step! Remove the casserole from the oven and let it rest on a cooling rack for 5-10 minutes. This allows the sauce to thicken slightly and makes serving much easier. Garnish with fresh parsley or chives if desired.
Recipe Notes & Tips for Success
Potato Shortcut: For an even faster version, you can use a 30-ounce bag of frozen shredded hash browns (thawed and patted dry). Skip the par-cooking step entirely.
Make it Spicy: Add a pinch of red pepper flakes to the beef or use Pepper Jack cheese for the topping.
Vegetable Boost: Stir in a cup of frozen peas, corn, or diced carrots with the beef sauce for an extra veggie serving.
Make-Ahead Master: Assemble the entire casserole (up to adding the final cheese topping), cover, and refrigerate for up to 24 hours. When ready to bake, add the cheese, and bake for 45-50 minutes, as it will be cold from the fridge.
Storage & Reheating: Store leftovers covered in the fridge for up to 4 days. Reheat individual portions in the microwave or cover the whole casserole with foil and reheat in a 350°F oven until warm.
