Ingredients
For the Base & Layers
-
2½ lb Yukon Gold potatoes (about 8–9 medium)—thinly sliced (~⅛” thick)
-
2 lb lean ground beef (such as 90/10)
-
1 cup sweet yellow onion, finely diced
-
1 Tbsp minced garlic
For the Creamy Sauce
-
10.5 oz condensed cream of mushroom soup
-
1 cup half-and-half
-
1 Tbsp onion powder
-
1½ tsp kosher salt
-
1 tsp freshly cracked black pepper
For the Cheese Topping
-
3 cups shredded Colby Jack cheese, divided
Instructions
1. Prep the Potatoes
Wash and thinly slice the potatoes (about ⅛” thick). Immediately place them in cold water to prevent browning while you prep other components. Drain well before layering.
2. Cook the Beef Filling
In a large skillet over medium-high heat, brown the ground beef, stirring and crumbling until no longer pink (about 5–7 minutes). Drain excess fat. Add diced onion and minced garlic, cooking another 2–3 minutes until softened. Remove from heat.
3. Mix the Sauce
In a medium bowl, whisk together the cream of mushroom soup, half-and-half, onion powder, salt, and pepper until smooth.
4. Assemble the Casserole
-
Preheat oven to 350 °F (177 °C).
-
Grease a 9×13-inch baking dish.
-
Layer 1: Spread one-third of the sliced potatoes over the bottom.
-
Layer 2: Scatter half of the cooked beef mixture.
-
Layer 3: Sprinkle 1 cup of shredded cheese.
-
Layer 4: Drizzle one-third of the sauce evenly.
Repeat Layers 1–4 two more times, finishing with the remaining sauce and the final 1½ cups of shredded cheese on top.
5. Bake
Cover the dish tightly with foil and bake for 1 hour 10 minutes. Remove foil and bake uncovered for another 20 minutes, until cheese is bubbly and potatoes tender.
6. Rest Before Serving
Let the casserole rest for about 15 minutes before serving—this helps the sauce thicken slightly for neater slices.
Make-Ahead & Storage
-
Prep ahead: Assemble the casserole and refrigerate uncovered up to 24 hours before baking. Add ~10–15 minutes to the baking time if baking straight from the fridge.
-
Leftovers: Store in an airtight container in the fridge for up to 4 days. Reheat in the oven or microwave until heated through.
-
Freezing: Freeze pre-baked or fully baked portions well sealed; thaw before reheating. Add 10–15 minutes to bake time if baking from frozen.
Tips for Perfection
-
Uniform potato slices help ensure even baking—use a mandoline if you have one.
-
Yukon Gold potatoes hold their shape well while getting tender. Russets work too but may become softer.
-
Drain the sliced potatoes well—this prevents extra liquid in the bake.
-
Cream of mushroom soup makes prep quick, but you can use cream of chicken or celery for variation.
-
Let it rest before serving—this allows the casserole to set and makes slicing easier.
Suggested Variations
-
Cheesy Mushroom Swap: Replace Colby Jack with sharp Cheddar for deeper cheese flavor.
-
Veggie Boost: Layer in 1–2 cups of frozen peas, diced carrots, or bell peppers between meat and potatoes.
-
Creamier Sauce: Stir in ¼ cup sour cream or plain Greek yogurt into the sauce mixture before baking.
-
Spicy Kick: Sprinkle smoked paprika or red pepper flakes into the sauce or on top for heat.
-
Slow Cooker Version: Brown beef and mix sauce on the stovetop; layer in slow cooker and cook 4–5 hours on low or until potatoes are tender.
Serving Ideas
-
Pair with a crisp green salad or roasted veggies to cut the richness.
-
Serve with garlic bread or dinner rolls—perfect for soaking up extra sauce.
-
Dish it into individual ramekins for personal servings or presentation.
