Why You’ll Love This Recipe

• One dish, no fuss. Everything layers into a single 9×13-inch baking dish and the oven does the work.
• Lighter, not bland. Lean ground beef and a Greek yogurt sauce keep it creamy while cutting the heaviness of a classic bake.
• Pantry staples only. No special shopping trip — potatoes, beef, cheese, and simple seasonings.
• Family approved. Mild, cheesy, and loaded with the flavors kids and adults both ask seconds of.
• Great leftovers. It reheats beautifully, so tomorrow’s lunch is already sorted.

Ingredients

• 1 tablespoon olive oil
• 1 medium yellow onion, diced
• 2 cloves garlic, minced
• 1 lb (450 g) lean ground beef (90–93% lean)
• 1 teaspoon smoked paprika
• 1 teaspoon garlic powder
• 1 teaspoon dried oregano
• Salt and black pepper, to taste
• 4 medium Russet potatoes (about 2 lb), peeled and sliced very thin (about ⅛ inch)
• 1 cup plain non-fat Greek yogurt
• ½ cup light sour cream
• 2 tablespoons milk
• 1 tablespoon cornstarch
• 1¼ cups shredded reduced-fat sharp cheddar cheese, divided
• 1¼ cups low-sodium beef broth
• 2 tablespoons chopped fresh chives or parsley, for garnish

Ingredient Notes and Substitutions

• Potatoes: Russet potatoes hold their shape and turn tender without falling apart. Yukon Gold also works. The thinner and more even the slices, the more evenly they cook — a mandoline makes this easy.
• Ground beef: Choose 90–93% lean so the bake stays rich but not greasy. Ground turkey is an easy swap.
• Greek yogurt: This is the healthy secret. It replaces most of the sour cream and heavy cream a classic loaded bake would use, and adds protein.
• Cheese: Reduced-fat sharp cheddar gives the strongest flavor for the amount used. Colby Jack or Monterey Jack melt nicely too.
• Beef broth: The potatoes drink it up as they bake, which is what makes them tender all the way through.

How to Make Loaded Beef and Potato Bake

Step 1: Heat the oven. Preheat to 375°F (190°C). Lightly grease a 9×13-inch baking dish.

Step 2: Brown the beef. Heat the olive oil in a large skillet over medium heat. Cook the onion for 3–4 minutes until soft. Add garlic for 30 seconds, then the ground beef. Cook, breaking it into crumbles, until browned. Drain extra fat, then season with smoked paprika, garlic powder, oregano, salt, and pepper.

Step 3: Mix the creamy sauce. In a bowl, whisk the Greek yogurt, light sour cream, milk, and cornstarch until smooth.

Step 4: Layer the first half. Arrange half the potato slices in the dish, overlapping slightly. Spread over half the beef, half the sauce, and ½ cup of the cheddar.

Step 5: Layer the second half. Repeat with the remaining potatoes, beef, and sauce. Pour the beef broth slowly and evenly over the whole dish.

Step 6: Bake covered. Cover tightly with foil and bake for 50 minutes.

Step 7: Bake uncovered. Remove the foil, sprinkle the remaining cheddar on top, and bake 15–20 minutes more, until the potatoes are fork-tender and the top is golden and bubbly.

Step 8: Rest and serve. Rest 10 minutes so the layers set. Scatter with chives or parsley and serve warm.

Pro Tips

• Slice thin, slice even. Thick slices are the number-one reason a potato bake comes out undercooked in the middle.
• Don’t skip the rest. Ten minutes out of the oven lets the sauce thicken so slices come out clean.
• Check the center. Poke a center potato slice with a fork before serving — it should slide in with no resistance.
• Make it loaded, your way. A sprinkle of cooked turkey bacon bits or sliced green onions on top gives the full loaded-baked-potato feel.

Serving Suggestions

This bake is a full meal on its own, but a crisp green salad or steamed green beans on the side balance it perfectly. A spoonful of extra Greek yogurt on top adds a cool, tangy finish.

Storage and Reheating

Refrigerate leftovers in an airtight container for up to 4 days. Reheat single portions in the microwave, or warm the whole dish, covered with foil, in a 325°F (165°C) oven for 20–25 minutes. To freeze, cool completely, wrap well, and freeze up to 2 months; thaw overnight in the fridge before reheating.

FAQs

Can I assemble this bake ahead of time?
Yes. Build the whole casserole, cover, and refrigerate up to 24 hours. Add about 10 extra minutes to the covered baking time if it goes into the oven cold.

Can I use sweet potatoes instead?
You can. The flavor turns slightly sweeter and the bake may need 5–10 minutes less uncovered time, so check tenderness early.

Why are my potatoes still firm?
They were likely sliced too thick, or the foil wasn’t sealed tightly. Cover and bake 10–15 minutes more — they will get there.

Is this recipe gluten free?
Yes, as written it is naturally gluten free. Just double-check your broth and cornstarch labels.

5. Repeat with the remaining potatoes, beef, and sauce. Pour the beef broth slowly and evenly over the whole dish.

Notes

Slice potatoes evenly, about 1/8 inch, so they cook at the same rate. Rest 10 minutes before serving for clean slices. Leftovers keep 4 days in the fridge or 2 months in the freezer.
