Ingredients for Cheesy Ground Beef Casserole

Here’s everything you’ll need to make this cozy masterpiece – I promise it’s all simple stuff! Measure as you go, or do what I do and just eyeball it with love:

• 1 lb ground beef (85% lean works best – enough fat for flavor but not greasy)
• 5 medium potatoes, peeled and cubed into 1-inch chunks (russets hold up great!)
• 1 small onion, finely chopped (I use yellow, but whatever makes you happy)
• 1½ cups shredded cheddar cheese (sharp is my fave for extra punch)
• 1 can cream of mushroom soup (10.5 oz – the secret sauce!)
• ½ cup milk (whole milk makes it extra creamy)
• 1 tsp garlic powder (not garlic salt – we control salt separately)
• 1 tsp paprika (smoked if you’re feeling fancy)
• Salt & pepper, to taste (I’m generous with both)
• 1 tbsp olive oil (for browning that beautiful beef)
• Fresh parsley, chopped (optional, but makes it pretty!)

Ingredient Substitutions & Notes

No stress if you need to swap things! This recipe is super flexible:

• Ground turkey works if you’re avoiding red meat – just add an extra tbsp oil
• Make it gluten-free with GF cream of mushroom soup (or blend fresh mushrooms with cream)
• Out of cheddar? Monterey Jack or Colby melt beautifully too
• For extra veggies, toss in some diced bell peppers with the onions
• Not a mushroom fan? Cream of celery or chicken soup work great

See? No need for a special grocery run – use what you’ve got!

How to Make Cheesy Ground Beef Casserole

Okay, let’s get cooking! This is where the magic happens – I’ll walk you through each step so your casserole turns out perfect. First things first: preheat that oven to 375°F (190°C) so it’s nice and hot when we’re ready to bake. Grab your favorite 9×13 baking dish and let’s go!

Step 1: Cook the Beef & Onions

Heat up that olive oil in a large skillet (I use my trusty cast iron) over medium heat. Toss in the onions first – let them get a little translucent, about 2 minutes. Then add the ground beef, breaking it up with your spoon as it browns. Cook until no pink remains, about 5-7 minutes. Here’s my trick: tilt the skillet and spoon out any excess grease (but leave a little for flavor!).

Step 2: Season & Layer the Potatoes

While the beef cooks, toss those cubed potatoes in a big bowl with garlic powder, paprika, salt, and pepper. Make sure every piece gets coated – this is where the flavor starts! In your greased baking dish, spread half the potatoes in an even layer. Top with half the beef mixture, then repeat. The layers should look like a delicious potato-beef lasagna!

Step 3: Assemble & Bake

Now for the creamy magic: whisk together the soup and milk until smooth (no lumps!). Pour it evenly over the whole casserole – it’ll seep down through the layers as it bakes. Sprinkle all that glorious cheddar on top. Cover tightly with foil and bake for 45 minutes. Then, remove the foil (hello, golden crust!) and bake another 15 minutes until bubbly and gorgeous. Let it rest 5 minutes before serving – trust me, it’s worth the wait!

Tips for the Best Cheesy Ground Beef Casserole

Here’s how I make sure this casserole turns out perfect every single time:

• Cube those potatoes evenly! I aim for 1-inch pieces—they cook through without turning mushy.
• Don’t skimp on the cheese—I like to sprinkle a little extra on top right before the final bake for that golden, bubbly crust.
• Let it rest 5 minutes after baking (the hardest part!). This keeps all that cheesy goodness from oozing everywhere when you cut into it.

Bonus tip: If the top isn’t as brown as you’d like, pop it under the broiler for 1-2 minutes—just keep an eye on it!

Serving Suggestions for Cheesy Ground Beef Casserole

Oh, let me tell you how I love to serve this hearty casserole – it’s practically a meal in itself, but I always add a few simple sides to make it extra special. A crisp green salad with tangy vinaigrette cuts through the richness perfectly. Garlic bread? Absolute must – those crusty edges are made for soaking up every last bit of cheesy sauce!

For portion sizes, this comfortably feeds my family of four with maybe a lunch portion leftover (if I’m lucky!). When we have company, I’ll stretch it further by adding extra sides – roasted veggies or steamed green beans work beautifully. And don’t forget the napkins – this is gloriously messy comfort food at its best!

Storing & Reheating Cheesy Ground Beef Casserole

Leftovers? (As if!) But if you somehow have some, here’s how to keep that cheesy goodness tasting fresh. Store cooled portions in airtight containers—glass works best for reheating. In the fridge, it stays delicious for 3-4 days. Freeze for up to 2 months (just thaw overnight in the fridge first).

For reheating, I always use the oven (350°F for 20-25 minutes) to keep the texture perfect. Microwave works in a pinch—cover with a damp paper towel to prevent rubbery cheese. Pro tip: Add a sprinkle of fresh cheese before reheating for that just-baked magic!

FAQs About Cheesy Ground Beef Casserole

I get asked about this potato beef bake all the time – here are the answers to the most common questions that pop up in my kitchen (and inbox!):

Can I freeze leftovers of this ground beef casserole?
Absolutely! This is one of those magical comfort food casseroles that freezes beautifully. Just cool completely, portion into freezer-safe containers, and it’ll keep for up to 2 months. Thaw overnight in the fridge before reheating.

What can I use instead of cream of mushroom soup?
No worries! Cream of celery or chicken soup work great. For a from-scratch version, blend sautéed mushrooms with some cream and a little flour. My gluten-free friends swear by using blended cauliflower with herbs!

How do I prevent the potatoes from turning mushy?
Cube them evenly (1-inch is perfect) and don’t overbake – that uncovered 15 minutes at the end is crucial for golden perfection. Russet potatoes hold up better than waxy varieties too.

Can I prep this cheesy potato casserole ahead?
You bet! Assemble everything (stop before baking), cover tightly, and refrigerate for up to 24 hours. Add 10-15 minutes to the baking time since it’ll be cold from the fridge.
