Yield: Serves approximately 6

Main Ingredients

  • 1 lb ground beef
    Provides the savory, hearty base of the casserole.
  • 1 small onion, chopped
    Adds aromatic flavor and moisture.
  • 2 cups thinly sliced russet or Yukon gold potatoes
    Thin slices help the potatoes cook fully and evenly.
  • Salt, pepper, paprika
    Seasonings used for the beef mixture.

Creamy Sauce

  • 1 can (10.5 oz) cream of mushroom soup
    Creates the rich, classic casserole texture.
  • 1/2 cup whole milk or heavy cream
    Helps thin the soup into a pourable sauce.
  • 1/2 cup sour cream (optional)
    Adds tang and additional creaminess.

Topping

  • 1 1/2 cups shredded cheddar cheese
    Melts into a golden, bubbly finish.
  • Fresh parsley for garnish
    Brightens the dish visually and adds a fresh note.

Tools & Equipment Needed

To ensure your cooking process is smooth and stress-free, gather the following tools:

  • Large skillet (for browning beef and onions)
  • Sharp knife and cutting board
  • Mixing bowls
  • 9×13-inch baking dish (or similar)
  • Measuring cups
  • Potato slicer (optional, but useful for thin, uniform slices)
  • Wooden spoon or spatula
  • Aluminum foil
  • Oven mitts
  • Cooling rack or heat-safe surface

Step-by-Step Instructions

These steps follow the recipe exactly as provided, ensuring perfect results.

1. Preheat the Oven

Set your oven to 375°F (190°C).
This gives the oven enough time to fully heat, ensuring the potatoes soften evenly.

2. Cook the Ground Beef and Onions

In a skillet over medium heat:

  1. Add 1 lb ground beef.
  2. Add the chopped small onion.
  3. Season with salt, pepper, and paprika.
  4. Cook until the beef is browned and the onions are softened.

This stage builds the savory flavor foundation for the entire casserole. Break the beef into small crumbles so it layers evenly in the baking dish.

3. Prepare the Creamy Sauce

In a separate bowl, combine:

  • 1 can (10.5 oz) cream of mushroom soup
  • 1/2 cup whole milk or heavy cream
  • 1/2 cup sour cream (optional)

Whisk until the mixture is smooth and pourable.

4. Assemble the Casserole

Lightly grease your baking dish.

  1. Spread the cooked beef and onion mixture evenly across the bottom.
  2. Layer the 2 cups thinly sliced potatoes on top of the beef.
  3. Pour the creamy sauce evenly over the potatoes.
  4. Sprinkle 1 1/2 cups shredded cheddar cheese across the top.

5. Bake Covered

Cover the dish tightly with aluminum foil.

Bake for 45 minutes.
Covering the dish traps steam, helping the potatoes cook through fully.

6. Finish Baking Uncovered

Remove the foil and return the casserole to the oven for an additional:

15 minutes, or until golden and bubbly on top.

7. Rest Before Serving

Let the casserole rest for 5–10 minutes.
This helps it set and makes serving easier.

8. Garnish

Top with fresh parsley and serve warm.

Ingredient Spotlight

Potatoes

Potatoes are the heart of a good casserole.

How to choose:

  • Look for firm, smooth potatoes without bruises.

How to store:

  • Keep in a cool, dark place (not the fridge).

Why they shine here:
Thin slices absorb the creamy sauce, giving every bite a silky texture.

Cheddar Cheese

Cheddar delivers a satisfying, melty topping.

Tips:

  • Use freshly shredded cheese for the smoothest melt.
  • Mild or sharp cheddar both work depending on flavor preference.

Pro Cooking Tips

  • Slice potatoes very thin (⅛ inch or less) for even cooking.
  • Drain excess fat from cooked beef for a cleaner texture.
  • Spread the beef mixture evenly so each scoop has balanced flavor.
  • Cover tightly with foil so steam tenderizes the potatoes.
  • Let the casserole rest before serving so it sets properly.

Storage & Freezing Guide

Refrigerator

Store leftovers in airtight containers for 4–5 days.

Freezing (After Baking)

  • Cool completely.
  • Wrap tightly.
  • Freeze up to 2 months.
  • Reheat in oven at 350°F until warmed through.

Do Not Freeze

  • Fresh (uncooked) dairy-heavy mixtures without proper wrapping.
  • Potatoes sliced too thick — they may become grainy.
