How to Make Ground Beef and Potatoes Casserole
Step 1: Prep Your Oven and Dish
Start by cranking up your oven to 375°F so it’s perfectly preheated. Grease a 9×13-inch baking dish with a little butter or nonstick spray—this means cleanup is effortless and ensures nothing sticks when you’re ready to serve up those golden, cheesy layers.
Step 2: Cook the Ground Beef Mixture
In a large skillet set over medium heat, warm the olive oil, then toss in your ground beef and chopped onion. Cook, stirring and breaking up the beef, until it’s beautifully browned and the onion turns soft and fragrant—this usually takes about 5 to 7 minutes. Add in the minced garlic and let it sizzle for another minute. If you notice excess fat, just drain it off.
Step 3: Mix Up the Creamy Sauce
In a small bowl, whisk together the cream of mushroom soup, milk, thyme, salt, and black pepper. This sauce is what transforms your Ground Beef and Potatoes Casserole into pure comfort—ultra-creamy and bursting with flavor. Mixing it first helps you pour it evenly over the layers.
Step 4: Layer the Casserole
Layer half the potato slices on the bottom of your prepared dish. Spoon on half of the beef mixture, sprinkle over half the shredded cheese, and then drizzle on half of the soup mixture. Repeat those layers once more with the rest of your ingredients, making sure you finish with cheese and sauce for a golden, bubbly top.
Step 5: Bake and Finish
Cover tightly with foil and slide the dish into the oven for 45 minutes. After this time, the potatoes will have started to soften and everything will smell irresistible. Remove the foil and continue baking, uncovered, for another 15 to 20 minutes until the top turns golden and bubbly and the potatoes are fork-tender. If you like, scatter on some chopped parsley for a final flourish.
How to Serve Ground Beef and Potatoes Casserole
Garnishes
A sprinkle of freshly chopped parsley goes a long way toward brightening up the hearty, rich tones of the casserole. For a little extra flavor, you can also add sliced green onions or a dusting of paprika just before serving.
Side Dishes
This Ground Beef and Potatoes Casserole is hearty enough to be the star of your dinner table. Pair it with a crisp green salad, steamed green beans, or maple-glazed carrots for a little color and crunch on the side. Warm dinner rolls or crusty bread are also perfect for soaking up every last drop of the creamy sauce!
Creative Ways to Present
Try baking the casserole in individual ramekins for a fun, personal-sized dinner or for stress-free entertaining. You can also turn leftovers into stuffed bell peppers by spooning the casserole into halved peppers and baking until heated through—a playful twist that’s sure to delight.
Make Ahead and Storage
Storing Leftovers
To store leftovers, let your Ground Beef and Potatoes Casserole cool to room temperature, then cover tightly and refrigerate for up to 4 days. The flavors somehow get even better as they mingle overnight, making lunch or busy weeknight dinners extra rewarding.
Freezing
This casserole is a dream for meal preppers! Assemble it completely, but don’t bake—just cover well with foil and freeze for up to 3 months. Thaw overnight in the fridge before baking as directed, or portion individual servings to freeze for super convenient meals on the go.
Reheating
To reheat, pop portions in the microwave until steaming hot, or cover leftovers and warm them in a 350°F oven for 20 to 30 minutes. If it looks a little dry, add a splash of milk or extra cheese before reheating to bring back that luscious texture.
FAQs
Can I use different kinds of potatoes in this casserole?
Absolutely! While russet potatoes yield the creamiest result, Yukon Golds or red potatoes will work wonderfully. Just make sure to slice them thin so they cook evenly in the oven.
Can I swap out the cream of mushroom soup?
Yes, you can! Cream of chicken or cream of celery soup work well, or you can use homemade white sauce if you’re looking for a fully from-scratch option. Just maintain the same consistency to keep your Ground Beef and Potatoes Casserole as creamy as possible.
What’s the best way to make this gluten-free?
Simply reach for a gluten-free condensed soup (there are several brands available now) and double-check all seasoning and cheese labels. Everything else in the casserole is naturally gluten-free, so you can serve it confidently to everyone at the table.
Can I add vegetables to the casserole?
Definitely! Stir in frozen peas, corn, or even diced carrots to the beef mixture before layering—this is an easy way to sneak in extra veggies and make your dinner even more colorful and nutritious.
What’s the best way to save time when prepping?
For quick assembly, slice potatoes using a mandoline for even, ultra-thin slices and have your cheese pre-shredded. You can also cook the beef mixture ahead of time and store it in the fridge, making the final layering and assembly super fast.
Final Thoughts
There’s nothing better than sharing a home-cooked meal that brings a smile to everyone’s face, and this Ground Beef and Potatoes Casserole does just that. It’s easy, satisfying, and utterly comforting. Whether you’re making it for family, friends, or stashing leftovers in the fridge, you’re sure to fall in love with every cheesy, creamy bite!
