How to Make Baked Potato Lasagna
1. Prepare the Potatoes
Preheat your oven to 375°F (190°C).
Wash and peel the potatoes if desired. Slice them very thinly and evenly, preferably using a mandoline.
Place the slices in a bowl and toss with olive oil, salt, pepper, and garlic powder.
Thin slices are important because they need to become tender during baking.
2. Cook the Bacon
Cook the bacon in a skillet until crisp.
Transfer it to a paper towel-lined plate and crumble once cool.
Reserve a little of the bacon grease if desired for cooking the beef.
3. Prepare the Beef
In a large skillet, cook the ground beef with the chopped onion over medium-high heat.
Cook until the beef is browned and the onion is tender.
Add the garlic, Italian seasoning, paprika, salt, and pepper.
Cook for another minute, then drain excess grease.
Stir in about half of the cooked bacon.
4. Make the Creamy Sauce
Melt the butter in a saucepan over medium heat.
Whisk in the flour and cook for about 1 minute.
Gradually whisk in the milk until smooth.
Continue cooking until the sauce thickens.
Remove from the heat and stir in the sour cream, garlic powder, and black pepper.
5. Start Layering
Grease a 9×13-inch baking dish.
Arrange a layer of sliced potatoes across the bottom.
Spread some of the beef mixture over the potatoes.
Drizzle with some creamy sauce.
Sprinkle with cheddar and mozzarella.
Repeat the layers until the ingredients are used.
Finish with a generous layer of cheese and the remaining bacon.
6. Bake
Cover the casserole tightly with aluminum foil.
Bake for approximately 45 minutes.
Remove the foil and continue baking for another 20–30 minutes, or until the potatoes are completely tender and the cheese is bubbling and golden.
If you’d like a more browned top, broil for 1–2 minutes at the end, watching carefully.
7. Rest Before Serving
Let the casserole rest for approximately 10–15 minutes before cutting.
This allows the creamy layers to settle and makes serving much easier.
Top with sliced green onions just before serving.
Tips for the Best Potato Lasagna
Slice the potatoes evenly. Uneven slices can result in some pieces being undercooked while others become too soft.
Don’t rush the baking. Potatoes need enough time to become fork-tender.
Use freshly shredded cheese. It generally melts more smoothly than pre-shredded cheese.
Let it rest. Cutting immediately can cause the layers to slide apart.
Season each component. Potatoes, meat, and sauce should all have enough seasoning for the finished dish to taste balanced.
Easy Variations
You can customize this casserole in plenty of ways.
Try adding:
- Cooked chicken instead of beef
- Pulled pork
- Diced ham
- Jalapeños
- Sautéed mushrooms
- Broccoli
- Spinach
- Caramelized onions
For an extra-loaded baked potato flavor, top individual servings with sour cream, green onions, and extra crispy bacon.
What to Serve With It
Because this dish is rich and filling, pair it with something fresh and light:
- Green salad
- Steamed broccoli
- Roasted vegetables
- Green beans
- Coleslaw
Storage and Reheating
Store leftovers in a covered container in the refrigerator for up to 3–4 days.
Reheat individual portions in the microwave or warm larger portions in the oven until heated through.
Final Thoughts
Baked Potato Lasagna is the ultimate comfort-food mashup. Tender potatoes replace traditional lasagna noodles, while seasoned beef, creamy sauce, crispy bacon, and layers of melted cheese create a dish that’s incredibly satisfying.
