There’s a stretch of the week where I start running low on ideas but the fridge is still full of basics: ground beef, a bag of potatoes, some cheese that needs using up. This casserole is what I make on those nights. It’s layered, it’s filling, and it doesn’t ask for anything unusual.
Thank you for reading this post, don't forget to subscribe!I like that it feels a little lighter than a typical potato bake without losing any of the comfort. Greek yogurt does some of the work that a full cup of sour cream would otherwise do, and the beef broth keeps the potatoes from drying out as everything bakes. It still comes out rich and cheesy where it matters.
My family doesn’t know the difference, honestly. They just know it’s the beef and potato one, and they ask for seconds.
Why You’ll Love This Dinner
Everything layers into one dish, so prep is straightforward even on a night when you’re low on energy. The potatoes cook down soft, the beef stays seasoned and hearty, and the cheddar melts into the top layer for that golden, bubbling finish everyone goes for first.
Using lean ground beef and a mix of Greek yogurt and light sour cream keeps this a little less heavy than a traditional loaded bake, though you’d never guess it from how creamy it turns out. It’s also a solid one for meal prep, since it holds up well in the fridge and reheats without losing much texture.
Ingredients
Nothing here is hard to find. A couple of notes worth knowing before you start: slice the potatoes evenly, about ⅛ inch thick, so both layers cook at the same rate. A mandoline makes quick work of this if you have one. Russet potatoes hold their shape well through the bake, though Yukon Gold works too if that’s what’s in the pantry.
- 1 tablespoon olive oil
- 1 medium onion, chopped
- 2 cloves garlic, minced
- 1 lb lean ground beef (90–93% lean)
- 1 teaspoon paprika
- 1 teaspoon dried oregano
- Salt and black pepper, to taste
- 4 medium Russet potatoes (about 2½–3 lb total), peeled and thinly sliced (about ⅛ inch thick)
- 1 cup plain non-fat Greek yogurt
- 1/2 cup light sour cream
- 1 tablespoon cornstarch
- 3/4 cup reduced-fat sharp cheddar cheese, divided
- 1 cup low-sodium beef broth
- Fresh parsley, chopped, for garnish
Step-by-Step Instructions
Preheat and prep the dish. Preheat your oven to 375°F. Lightly grease a 9×13-inch baking dish and set it aside.
Cook the beef. Heat the olive oil in a large skillet over medium heat. Add the onion and cook for 3-4 minutes until softened, then stir in the garlic for about 30 seconds, just until fragrant. Add the ground beef and cook until browned throughout, breaking it into small crumbles as it cooks. Drain any excess fat if needed, then season with the paprika, oregano, salt, and pepper.
Mix the cream layer. In a medium bowl, whisk together the Greek yogurt, light sour cream, and cornstarch until completely smooth. The cornstarch helps this layer thicken nicely in the oven instead of staying loose.
Build the first layer. Arrange half of the sliced potatoes in an even layer in the prepared dish. Top with half of the beef mixture, spread half of the yogurt mixture evenly over that, then sprinkle with half of the cheddar.
Repeat for the second layer. Layer the remaining potatoes, beef, yogurt mixture, and cheddar in the same order.
Add the broth. Slowly pour the beef broth around the edges and evenly over the top of the casserole. It looks like a lot of liquid going in, but the potatoes absorb most of it as everything bakes. Pouring it slowly and spreading it around, rather than dumping it in one spot, helps the potatoes cook evenly.
Bake covered, then uncovered. Cover the dish tightly with foil and bake for 45 minutes. Remove the foil and continue baking for another 15-20 minutes, until the potatoes are fork-tender and the cheese on top is melted and lightly golden.
Rest before serving. Let the casserole sit for 10 minutes before cutting in. This helps the layers set so you get cleaner slices. Garnish with fresh parsley.
What to Serve With It
A simple green salad or some steamed broccoli rounds this out nicely without adding much extra work. Crusty bread is good to have around too, mostly for scooping up whatever sauce is left on the plate. A little extra sour cream or a sprinkle of chives on top never hurts either.
Variations
Ground turkey works in place of the beef if you want to lighten it up further, though the flavor will be a bit milder. Monterey Jack or Colby are easy swaps for the cheddar if that’s what you have on hand. For an even lighter version, you can replace all of the sour cream with more Greek yogurt. If your potatoes come out extra large, you likely won’t need every slice, since the goal is two even layers without overcrowding the dish.
Storage
Refrigerate leftovers in an airtight container for up to 3-4 days. To reheat, cover with foil and warm in a 325°F oven until heated through, about 20-30 minutes, or microwave individual portions. This casserole also freezes well for up to 2 months. Thaw it overnight in the refrigerator before reheating so the texture stays as close to fresh as possible.
Frequently Asked Questions
Can I assemble this ahead of time?
Yes, you can put it together up to a day in advance and refrigerate it covered. If baking straight from the fridge, add a few extra minutes to the covered baking time.
Why is the potato layer sometimes thin?
Potato size varies quite a bit, so if yours are on the smaller side, you may end up using more slices than expected to fully cover each layer. The layers are meant to be thin rather than thick in a 9×13 dish.
Can I use a different potato?
Yukon Gold potatoes work well as a substitute for Russets. Just keep the slices thin and even so both types cook through at the same rate.
Is it normal for there to be a lot of liquid before baking?
Yes, the broth looks like more than you’d expect going in, but the potatoes soak most of it up as the casserole bakes covered.
Can I use a different ground meat?
Ground turkey or a plant-based ground alternative can work in place of the beef, though the texture and flavor will shift slightly.
How do I know the potatoes are done?
Test a slice with a fork after the covered baking time. It should slide in easily. If there’s resistance, cover and bake a bit longer before uncovering.
A Simple One to Repeat
This is one of those dinners that doesn’t need much thought once it’s in the oven. It’s filling, it reheats well, and it turns a handful of basic ingredients into something the whole table will actually finish.
