- Black pepper – 1 tsp (2 g)
- Paprika – 1 tsp (2 g)
- Dried oregano – 1 tsp (1 g)
- All-purpose flour – 2 Tbsp (30 ml | ~16 g)
- Beef broth – 1 cup (240 ml | ~240 g)
- Milk – ½ cup (120 ml | ~120 g)
- Cheddar cheese, shredded – 1 cup (240 ml | ~113 g)

Ingredient Notes and Substitutions
- Potatoes: Russet or Yukon Gold potatoes work best. Slice them thin and evenly so they cook through properly.
- Ground beef: Use lean ground beef (85–90%) to avoid excess grease. Ground turkey or chicken are excellent lighter substitutes.
- Milk: Whole or 2% milk gives the best texture. Unsweetened soy or oat milk works for a dairy-free version.
- Cheese: Sharp cheddar adds depth, but Colby-Jack or a dairy-free shredded cheese also work well.
- Seasonings: Paprika and oregano add gentle warmth without overwhelming the dish.
Step-by-Step Instructions
Step 1 – Prepare the Potatoes
Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish.
Peel the potatoes and slice them thinly (about ⅛-inch thick). Uniform slices ensure even baking.
Step 2 – Cook the Ground Beef Mixture
Heat butter or oil in a large skillet over medium heat. Add the diced onion and cook for 3–4 minutes until soft. Stir in the garlic and thyme and cook for another 30 seconds.
Add the ground beef and cook until fully browned, breaking it into small crumbles as it cooks. Season with salt, black pepper, paprika, and oregano. Drain excess fat if needed.
Step 3 – Make the Sauce
Sprinkle the flour evenly over the beef mixture and stir well. Cook for 1 minute to remove the raw flour taste.
Slowly pour in the beef broth and milk, stirring constantly. Simmer for 3–5 minutes until the mixture thickens into a light, gravy-like sauce.
Step 4 – Assemble the Casserole
Arrange half of the sliced potatoes evenly in the prepared baking dish. Spoon half of the beef mixture over the potatoes.
Repeat with the remaining potatoes and beef mixture, spreading everything evenly.
Step 5 – Bake
Cover the dish tightly with foil and bake for 45 minutes, or until the potatoes are tender when pierced with a fork.
Remove the foil, sprinkle the shredded cheddar cheese evenly over the top, and return to the oven uncovered for 10–15 minutes, until the cheese is melted and bubbly.
Let the casserole rest for 10 minutes before serving. Garnish with chopped parsley if desired.
Pro Tips for Success
- Slice potatoes evenly for consistent texture throughout the casserole
- Drain excess grease from the beef to avoid a heavy or oily result
- Cover tightly while baking so the potatoes steam and soften fully
- Rest before serving to help the layers set and slice cleanly
- Use a mandoline slicer if you have one for perfectly even potatoes
Flavor Variations
This ground beef potato casserole is easy to adapt to your taste.
- Veggie-packed version: Add peas, carrots, or corn to the beef mixture
- Extra creamy: Stir ¼ cup (60 ml | ~60 g) sour cream or a dairy-free alternative into the sauce
- Spicy twist: Add ¼–½ tsp chili flakes or smoked paprika
- Italian-inspired: Swap oregano for Italian seasoning and use mozzarella on top
- Tex-Mex style: Add cumin and top with a mild cheddar blend
Serving Suggestions
This casserole is satisfying on its own, but pairs nicely with lighter sides.
- Simple green salad with vinaigrette
- Steamed green beans or broccoli
- Roasted vegetables
- Crusty bread or dinner rolls
Storage and Freezing Instructions
- Refrigerator: Store leftovers in an airtight container for up to 4 days.
- Freezing: Wrap tightly and freeze for up to 2 months. Thaw overnight in the refrigerator before reheating.
