Easy Hamburger Potato Casserole – Comfort Food Favorite

There’s something magical about a casserole that brings everyone to the table—no fancy plating required, just a big scoop of warmth and nostalgia. This Easy Hamburger Potato Casserole is one of those dishes that feels like a hug in every bite. I first made it on a chilly autumn evening when all I wanted was something hearty, simple, and utterly comforting. The aroma of seasoned beef and tender potatoes bubbling away in the oven was enough to make my family wander into the kitchen, noses first. And just like that, it became a regular in our rotation.

Ingredients You’ll Need

Gathering these simple ingredients is half the joy—they’re pantry staples with big flavor potential. Here’s what you’ll need:

• 1 lb ground beef – I prefer 80/20 for the perfect balance of flavor and juiciness, but leaner works too.
• 4 cups thinly sliced potatoes – Yukon Golds are my go-to for their creamy texture, but russets hold up well too.
• 1 small onion, diced – Yellow or white onions add a sweet depth.
• 1 can (10.5 oz) cream of mushroom soup – The cozy glue of this casserole! Cream of celery works if you’re not a mushroom fan.
• 1/2 cup milk – Whole milk makes it extra rich, but any kind will do.
• 1 cup shredded cheddar cheese – Sharp cheddar is lovely, but feel free to mix in Monterey Jack or Colby.
• 1 tsp garlic powder – A little warmth and savoriness.
• Salt and pepper to taste – Don’t be shy—season as you go!
• 1 tbsp olive oil – For sautéing the onions and browning the beef.

Let’s Make It Together

This casserole comes together in three easy steps—brown, layer, and bake. Here’s how:

1. Preheat and Prep: Start by preheating your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish—this ensures easy serving later.
2. Brown the Beef: In a skillet over medium heat, warm the olive oil and sauté the onions until they’re soft and translucent. Add the ground beef, breaking it up with a spoon as it cooks. Sprinkle in the garlic powder, salt, and pepper, and cook until the beef is no longer pink. Drain any excess grease if needed.
3. Layer with Love: In a large bowl, whisk together the cream of mushroom soup and milk until smooth. Arrange half of the sliced potatoes in the baking dish, followed by half of the beef mixture. Pour half of the soup mixture over the top, then repeat the layers. Finish with a generous sprinkle of cheddar cheese—because everything’s better with cheese.
4. Bake to Perfection: Cover the dish with foil and bake for 45 minutes. Remove the foil and bake for another 15–20 minutes, or until the potatoes are fork-tender and the cheese is golden and bubbly. Let it rest for 5 minutes before serving—patience is rewarded with melty goodness!

Tip: If your potatoes are thicker, they may need a little extra time. Just poke them with a fork to check for tenderness.

There’s something magical about the way ground beef, tender potatoes, and melty cheese come together in this hamburger potato casserole. It’s the kind of meal that brings everyone to the table with eager anticipation. Whether you’re feeding a hungry family or meal prepping for the week, this dish delivers comfort in every bite.

Pro Tips for the Best Hamburger Potato Casserole

• Brown your beef well: Take the extra minute to get a nice sear on your ground beef—it adds incredible depth of flavor.
• Slice potatoes evenly: Use a mandoline or sharp knife to get uniform 1/4-inch slices so everything cooks evenly.
• Layer strategically: Start with potatoes, then beef mixture, then cheese for perfect distribution in every bite.
• Let it rest: Allow the casserole to sit for 5-10 minutes after baking for cleaner slices.

Delicious Variations to Try

This recipe is wonderfully adaptable to what you have on hand or your family’s preferences:

• Cheese lovers: Add a layer of cream cheese between the potatoes and beef mixture
• Vegetable boost: Mix in sautéed mushrooms, bell peppers, or spinach with the beef
• Spicy twist: Use pepper jack cheese and add diced jalapeños
• Lighter option: Substitute ground turkey and reduced-fat cheese

What to Serve With Your Casserole

This hearty dish stands well on its own, but these sides complement it perfectly:

• Crisp green salad with tangy vinaigrette
• Steamed green beans or roasted broccoli
• Buttery dinner rolls or crusty bread
• Pickled vegetables for a bright contrast

Storage and Reheating Tips

Leftovers (if you’re lucky enough to have any!) keep beautifully:

• Refrigerator: Store covered for 3-4 days
• Freezer: Portion and freeze for up to 3 months (thaw overnight before reheating)
• Reheating: Warm in a 350°F oven until heated through (about 20 minutes), or microwave individual portions with a damp paper towel to prevent drying

Frequently Asked Questions

Can I use frozen hash browns instead of fresh potatoes?

Absolutely! Thawed frozen hash browns work well and save time. Just pat them dry before using.

What if I don’t have cream of mushroom soup?

Cream of chicken or celery soup make fine substitutes, or make a quick white sauce with butter, flour, and milk.

Can I assemble this ahead of time?

Yes! Prepare up to the baking step, cover tightly, and refrigerate for up to 24 hours. Add 10-15 minutes to the baking time.

How can I make this gluten-free?

Use gluten-free cream soup or make your own sauce, and double-check that your Worcestershire sauce is gluten-free.

At the end of a long day, there’s nothing quite like scooping into a bubbling dish of this hamburger potato casserole.
