Picture this: a chilly autumn evening, the kitchen windows slightly fogged from the warmth inside, and the rich aroma of garlic and herbs filling the air. That’s the scene in my house whenever I make this incredible Garlic Butter Ground Beef & Potato Casserole. I first developed this recipe during a particularly hectic week when I needed something comforting yet simple enough to throw together between work and family activities. What emerged from my oven that night became an instant family favorite—so much so that my kids now request it weekly.
There’s something magical about how the humble potato transforms when layered with seasoned ground beef and that glorious garlic butter sauce. The potatoes become tender and soak up all the flavors, while the beef develops this wonderful savory depth. Around here, we call this “hug food“—the kind of meal that just makes everything feel right with the world. Whether you’re feeding a hungry family or prepping meals for the week ahead, this dish delivers on every level.

What You’ll Need
When I’m gathering equipment for this recipe, I always think about efficiency. From experience, using a mandoline slicer makes the potato prep so much faster and ensures even cooking. I learned this the hard way after spending what felt like hours hand-slicing potatoes—never again! A good 9×13 inch baking dish is essential, and I prefer ceramic or glass because they distribute heat more evenly than metal pans.
The key tools serve specific purposes: your skillet for browning the beef properly, a whisk for emulsifying the garlic butter sauce, and that baking dish for creating those perfect layers. What works for me is having everything within arm’s reach before I start—it makes the process flow so smoothly.
INGREDIENTS
The moment I start pulling these ingredients from my pantry, the memories flood back. I can still recall the first time I made this for my parents—my dad’s face when he took that first bite told me everything I needed to know. There’s something about the scent of garlic hitting warm butter that immediately makes the kitchen feel like home.
- 2 lbs russet potatoes, sliced ¼-inch thick
- 1½ lbs ground beef (80/20 blend works best)
- 1 large yellow onion, diced
- 4 cloves garlic, minced
- ½ cup unsalted butter
- 2 cups beef broth
- 1 cup heavy cream
- 2 tsp Worcestershire sauce
- 1 tsp dried thyme
- 1 tsp smoked paprika
- 2 cups shredded cheddar cheese
- Salt and freshly ground black pepper to taste
- Fresh parsley for garnish
PREPARATION
One thing I’ve learned from making this repeatedly: don’t rush the browning process. That initial step where the beef develops those crispy, caramelized bits? That’s where so much flavor comes from. I once tried to speed through this stage and ended up with steamed beef instead—lesson learned! Take your time here, and you’ll be rewarded with incredible depth in your final dish.
- Preheat your oven to 375°F (190°C). Grease your 9×13 baking dish thoroughly.
- In a large skillet over medium-high heat, brown the ground beef with the diced onion, breaking it into small pieces as it cooks. This should take about 8-10 minutes until properly browned.
- Add the minced garlic and cook for 1 minute until fragrant. Drain excess fat if necessary, then stir in Worcestershire sauce, thyme, paprika, salt, and pepper.
- In a saucepan, melt butter over medium heat. Whisk in beef broth and heavy cream, heating through but not boiling.
- Layer half the potato slices in your prepared dish, followed by all the beef mixture, then remaining potatoes.
- Pour the garlic butter sauce evenly over everything, making sure it seeps between layers.
- Cover with foil and bake for 30 minutes. Remove foil, top with cheese, and bake uncovered for 15 more minutes until potatoes are tender and cheese is golden.
- Let rest for 10 minutes before serving—this allows the sauce to thicken perfectly.
- Garnish with fresh parsley and serve hot.

Choosing Your Ingredients Wisely
The quality of your ground beef makes a noticeable difference here. I typically choose an 80/20 blend because the extra fat content keeps the meat moist and adds flavor throughout the baking process. When it comes to potatoes, russets are my go-to for their starchy quality that helps thicken the sauce as they cook. One trick I’ve picked up: if you have time, soak the sliced potatoes in cold water for 20 minutes before assembling—this removes excess starch and prevents them from sticking together.

Perfecting Your Layers
Creating distinct layers might seem fussy, but it’s what makes this casserole exceptional. When I’m building the layers, I make sure the potato slices overlap slightly—this creates a more stable structure and ensures every bite includes that wonderful potato texture. A note about the cheese: I often mix sharp cheddar with a bit of mozzarella for both flavor and that beautiful golden-brown top. The beauty of this recipe is how each component maintains its identity while contributing to the whole.
Adapting for Different Diets
This recipe adapts beautifully to various dietary needs. For a lighter version, I’ve successfully used ground turkey and replaced the heavy cream with half-and-half. When my vegetarian friends visit, I substitute the beef with lentils and use vegetable broth—the results are surprisingly satisfying. What makes this special is how the garlic butter sauce ties everything together regardless of the protein you choose.
FREQUENTLY ASKED QUESTIONS
Can I prepare this Garlic Butter Ground Beef & Potato Casserole ahead of time?
Absolutely! I often assemble this dish up to a day in advance. Just cover and refrigerate, then add 10-15 minutes to the baking time since it will be cold from the fridge. The flavors actually develop more deeply when it rests overnight.
What’s the best way to store leftovers?
This keeps beautifully in the refrigerator for up to 4 days. I usually portion it into containers for easy lunches. The potatoes absorb more sauce as it sits, making each subsequent serving even more flavorful in my opinion.
Can I freeze this casserole?
You can freeze it before or after baking, though I prefer freezing before. Thaw completely in the refrigerator before baking as directed. The texture remains excellent, though the potatoes may soften slightly more upon reheating.
