Ingredients
| Ingredient | Quantity |
| Beef, cut into small cubes or ground beef | 1½ lb (700 g) |
| Medium potatoes, peeled and cubed | 4–5 |
| Medium onion, sliced or chopped | 1 |
| Garlic cloves, minced | 2 |
| Condensed cream of mushroom soup | 1 can (about 10.5 oz / 300 g) |
| Beef or chicken broth | ½ cup (120 ml) |
| Italian seasoning or paprika | 1 teaspoon |
| Salt | 1 teaspoon, or to taste |
| Black pepper | ½ teaspoon |
| Shredded mozzarella, cheddar, or cheese blend | 1½ cups |
| Fresh parsley, chopped | For garnish |
| Olive oil or cooking spray | For greasing |
Step-by-Step Instructions
1. Prepare the Oven and Baking Dish
Preheat your oven to 375°F (190°C). Lightly grease a large baking dish with olive oil or cooking spray.
2. Prepare the Potatoes
Peel the potatoes if desired and cut them into evenly sized cubes, approximately ¾ inch. Arrange them in an even layer in the prepared baking dish.
Add the chopped onion and minced garlic over the potatoes.
3. Prepare the Beef
If using beef cubes, cut them into small, evenly sized pieces. For the best flavor and texture, quickly brown them in a skillet with a little olive oil before adding them to the casserole.
If using ground beef, cook it in a skillet until browned, breaking it into small pieces. Drain excess fat if necessary.
Spread the prepared beef evenly over the potatoes and onions.
4. Make the Creamy Sauce
In a medium bowl, whisk together the condensed cream of mushroom soup, beef broth, Italian seasoning or paprika, salt, and black pepper until smooth.
Pour the creamy mixture evenly over the beef and potatoes.
5. Bake the Casserole
Cover the baking dish tightly with aluminum foil and bake for 45–50 minutes.
Check the potatoes with a fork. They should be tender, and the beef must be fully cooked. If the potatoes are still firm, cover the dish again and continue baking in 5–10-minute increments.
6. Add the Cheese
Remove the aluminum foil and sprinkle the shredded cheese evenly over the casserole.
Return the dish to the oven, uncovered, for another 10–15 minutes, until the cheese is melted, bubbly, and lightly golden.
7. Garnish and Serve
Remove the casserole from the oven and let it rest for 5–10 minutes before serving. Sprinkle with freshly chopped parsley and serve warm.
Best Tips
Cut the potatoes into similar-sized cubes so they cook evenly. Browning the beef before baking adds a deeper, richer flavor, especially when using beef cubes. Keep the baking dish covered during the first stage to help the potatoes soften in the creamy sauce. For a beautifully golden topping, use freshly shredded cheese and finish the casserole under the broiler for 1–2 minutes, watching carefully.
Best Ingredient Options
Russet potatoes work well because they become soft and fluffy during baking, while Yukon Gold potatoes hold their shape and have a naturally buttery texture. Cheddar adds a stronger cheese flavor, mozzarella creates a stretchy melted topping, and a combination of both gives you the best of both textures. Beef broth provides a rich savory taste, while chicken broth offers a milder flavor.
Recipe Variations
For extra vegetables, add sliced mushrooms, peas, carrots, or diced bell peppers. You can make the casserole spicier with a pinch of chili flakes or cayenne pepper. For a richer sauce, stir 2–3 tablespoons of sour cream into the soup mixture. You can also add a little grated Parmesan cheese over the cheddar before baking.
What to Serve With This Casserole
Serve this cheesy beef and potato casserole with a crisp green salad, steamed broccoli, roasted green beans, or glazed carrots. Garlic bread or warm dinner rolls are also excellent choices for soaking up the creamy sauce.
Make-Ahead Instructions
You can prepare the beef, potatoes, onions, and creamy sauce ahead of time. Assemble the casserole in a baking dish, cover tightly, and refrigerate for up to 24 hours before baking.
For the best texture, keep the cheese separate and add it during the final baking stage. If baking directly from the refrigerator, allow extra cooking time and check that the potatoes are tender before adding the cheese.
Storage
Allow leftovers to cool completely, then transfer them to an airtight container. Refrigerate for up to 3–4 days.
Reheating
Reheat individual portions in the microwave until hot throughout, stirring or checking the center as needed. To reheat a larger portion, cover it with foil and place it in a 350°F (175°C) oven until heated through. Add a splash of broth if the sauce has thickened too much.
Freezing
For best results, freeze the casserole after baking and cooling completely. Divide it into freezer-safe portions, wrap tightly, and freeze for up to 2 months. Thaw overnight in the refrigerator before reheating. Potatoes may become slightly softer after freezing, but the casserole will still be delicious.
Common Mistakes to Avoid
Cutting the potatoes into large, uneven pieces can leave some portions undercooked. Skipping the initial beef browning can also reduce the depth of flavor. Avoid adding the cheese too early, as it may become overly browned before the potatoes are tender. Finally, always check the internal temperature of the beef: whole beef pieces should reach a safe temperature of at least 145°F (63°C), followed by a 3-minute rest; ground beef should reach 160°F (71°C).

Frequently Asked Questions
Can I use ground beef instead of beef cubes?
Yes. Ground beef works perfectly in this casserole. Brown it in a skillet and drain any excess fat before layering it over the potatoes.
Do I need to cook the beef before baking?
Browning the beef first is recommended for better flavor and more reliable cooking. Ground beef should always be browned before assembling the casserole. If using beef cubes, sear them first and make sure the finished dish reaches a safe internal temperature.
Can I use cream of chicken soup instead of cream of mushroom?
Absolutely. Cream of chicken soup creates a smooth, mild sauce and works just as well.
How do I know when the potatoes are done?
Insert a fork or knife into a potato cube. It should slide through easily without resistance.
What cheese is best for this casserole?
Cheddar, mozzarella, Monterey Jack, or a combination of these cheeses all work beautifully.
Can I prepare this casserole the night before?
Yes. Assemble it, cover it tightly, and refrigerate for up to 24 hours. Bake until the potatoes are tender and the beef is fully cooked, allowing extra time if it goes into the oven cold.
Can I make this casserole without mushrooms?
Yes. Use condensed cream of chicken soup instead of cream of mushroom soup for a creamy sauce without mushroom flavor.
