Ingredients
For the Casserole:
-
1 ½ pounds ground beef (85% lean preferred)
-
1 medium onion, finely chopped
-
3 cloves garlic, minced
-
1 teaspoon salt
-
½ teaspoon black pepper
-
½ teaspoon paprika
-
½ teaspoon dried thyme (optional)
-
1 tablespoon Worcestershire sauce
-
3 tablespoons all-purpose flour
-
1 ½ cups beef broth
-
1 cup milk or heavy cream
-
2 pounds potatoes (about 5–6 medium), thinly sliced
-
2 cups shredded cheddar cheese (divided)
-
½ cup shredded mozzarella (for extra creaminess)
-
2 tablespoons butter
-
1 tablespoon olive oil
For Garnish:
-
Fresh parsley, chopped
-
A sprinkle of paprika (optional)
Instructions
Step 1: Preheat and Prepare
Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with butter or nonstick spray. This will prevent the potatoes and cheese from sticking and ensure a smooth release after baking.
Step 2: Brown the Ground Beef
-
In a large skillet over medium-high heat, add olive oil.
-
Once hot, add the ground beef and cook until it starts to brown.
-
Add the onion and garlic, and cook until the onion turns soft and translucent (about 5 minutes).
-
Season with salt, pepper, paprika, thyme, and Worcestershire sauce for depth.
-
Drain excess fat if needed — you want the mixture moist but not greasy.
Step 3: Make the Creamy Beef Sauce
-
Sprinkle flour over the cooked beef mixture and stir until evenly coated.
-
Gradually pour in beef broth, whisking as you go to avoid lumps.
-
Stir in milk and cook until the sauce thickens into a creamy consistency (about 5 minutes).
-
Taste and adjust seasoning — this sauce should be flavorful, as it will coat your potatoes later.
Step 4: Prepare the Potatoes
-
Wash, peel (optional), and thinly slice the potatoes using a mandoline slicer or a sharp knife.
-
Try to keep slices about ⅛ inch thick to ensure even cooking.
-
Rinse the slices briefly in cold water and pat dry to remove excess starch — this helps them bake evenly and stay firm.
Step 5: Layer the Casserole
-
Spread half of the potatoes in the prepared dish.
-
Spoon half of the beef mixture over the potatoes, spreading it evenly.
-
Sprinkle with 1 cup of cheddar cheese.
-
Add another layer of potatoes, followed by the remaining beef mixture.
-
Top with the rest of the cheddar and mozzarella cheese.
-
Dot the surface with small pieces of butter for extra richness.
Step 6: Bake the Casserole
-
Cover the dish with aluminum foil and bake for 45 minutes.
-
Remove the foil and bake uncovered for another 15–20 minutes, or until the potatoes are tender and the top is golden and bubbly.
-
If you want a crispier cheese crust, broil for the last 2–3 minutes — but watch it closely to prevent burning.
Step 7: Rest and Serve
Once baked, let the casserole rest for about 10 minutes before cutting into portions. This helps the layers set and makes serving much easier.
Sprinkle with fresh parsley and a light dusting of paprika before serving.
Serving Suggestions
Pair your Ground Beef Potato Casserole with simple sides to balance its richness:
-
A crisp green salad with lemon vinaigrette
-
Steamed vegetables (like broccoli or green beans)
-
Warm dinner rolls or garlic bread
-
A refreshing iced tea or sparkling lemonade
If serving this for a family dinner, consider adding a small bowl of sour cream or ranch dressing on the side for dipping — it complements the cheesy potatoes beautifully.
Tips for Perfect Results
-
Choose the Right Potatoes:
Russet or Yukon Gold potatoes are best — they hold their shape and absorb flavor without getting mushy. -
Don’t Rush the Sauce:
Allowing the beef sauce to thicken ensures the casserole won’t turn watery. The flour and broth combo is key. -
Try Different Cheeses:
Mix it up with Monterey Jack, Pepper Jack, or Gruyère for a unique twist. -
Make Ahead:
Assemble the casserole a day in advance, cover, and refrigerate. Bake it fresh when ready to serve (add 10 extra minutes if baking from cold). -
Add Veggies for Nutrition:
You can sneak in diced carrots, peas, or even spinach between the layers for extra color and nutrients. -
Turn Up the Heat:
For a spicier version, add red pepper flakes or diced jalapeños to the beef mixture.
Storage & Reheating
To Store:
Let leftovers cool completely. Store in an airtight container in the refrigerator for up to 4 days.
To Reheat:
-
Microwave: Reheat individual portions for 1–2 minutes until hot.
-
Oven: Cover with foil and warm at 350°F (175°C) for 20–25 minutes.
To Freeze:
You can freeze the casserole (baked or unbaked) for up to 3 months. Thaw overnight in the fridge before reheating or baking.
Variations
-
Loaded Casserole: Add bacon bits, green onions, and a dollop of sour cream on top before serving.
-
Tex-Mex Style: Stir in taco seasoning, corn, and black beans, and replace cheddar with a Mexican cheese blend.
-
Cream of Mushroom Twist: Mix in a can of cream of mushroom soup for an even richer flavor.
-
Vegetarian Version: Substitute the beef with plant-based ground meat or sautéed mushrooms.
