Ingredients

For the Filling

  • 1 lb (450g) lean ground beef (85/15 recommended)
  • ½ cup diced yellow onion (~1 small)
  • 1 green bell pepper, diced (~1 cup)
  • 2 cloves garlic, minced
  • 2–3 medium Russet potatoes, peeled and thinly sliced (~4 cups)
  • Salt and freshly ground black pepper, to taste

For the Creamy Sauce

  • 1 (10.75 oz) can condensed cream of mushroom soup (regular or gluten-free)
  • 1 cup full-fat sour cream (Greek yogurt works in a pinch)

For Layering & Topping

  • 1 cup shredded sharp cheddar cheese
  • 1 cup French fried onions (like French’s® – divided use)
  • Optional garnishes:
    • Sliced green onions
    • Chopped fresh parsley

Step-by-Step Instructions

1. Preheat Oven

  • Preheat oven to 375°F (190°C).
  • Lightly grease a 9×13-inch baking dish with butter, oil, or nonstick spray.

2. Cook the Beef & Veggies

In a large skillet over medium heat:

  • Add ground beef and cook 5–7 minutes, breaking it apart as it browns.
  • Add diced onion, bell pepper, and minced garlic.
  • Cook 5–6 minutes more, until vegetables are softened and beef is fully cooked.
  • Drain any excess fat. Season with salt and pepper. Set aside.

Don’t skip draining —greasy filling = soggy casserole.


3. Make the Creamy Sauce

In a bowl:

  • Stir together cream of mushroom soup and sour cream until smooth and well blended.

4. Assemble the Layers

In the prepared baking dish, layer in this order:

  1. First layer: Half of the thinly sliced potatoes (arranged in an even layer)
  2. Second layer: All of the beef and vegetable mixture
  3. Third layer: Half of the cheese
  4. Fourth layer: Half of the sauce mixture
  5. Repeat: Remaining potatoes, remaining sauce, and remaining cheese

Top tip: Overlap potato slices slightly to prevent gaps.


5. Bake Covered

  • Cover tightly with aluminum foil.
  • Bake 45 minutes—this steams the potatoes until tender.

6. Add the Crunchy Topping

  • Remove foil.
  • Sprinkle the top generously with French fried onions.
  • Return to oven and bake uncovered for 10–15 minutes, until:
    • Potatoes are fork-tender
    • Top is golden brown
    • Onions are crisp (watch closely—they burn fast!)

7. Rest & Serve

  • Let stand 5–10 minutes before serving—this helps the layers set for cleaner scooping.
  • Garnish with sliced green onions or chopped parsley if desired.

Serve warm with:

  • A crisp green salad
  • Steamed green beans
  • Or all by itself—it’s a full meal!

You Must Know

  • Slice potatoes evenly (~⅛ inch thick)—uniform cuts ensure even cooking.
  • Use full-fat sour cream —low-fat versions may separate during baking.
  • Drain beef well —prevents greasiness and sogginess.
  • Don’t stir after assembling —layers are key!
  • Add onions at the end —keeps them crispy instead of soggy.

Storage Tips

  • Store leftovers in an airtight container in the fridge for up to 4 days.
  • Reheat in oven at 350°F for 15 mins (best texture). Microwave works but softens the onions.
  • Freeze before adding onions: Wrap tightly and freeze up to 3 months. Thaw overnight, then bake uncovered + add onions last 10 mins.
