• 2 cloves garlic, minced

• 1½ cups rich bolognese / marinara sauce

• Salt, black pepper, and Italian seasoning, to taste

The Light & Runny Bechamel Sauce

• 1 tbsp butter

• 1 tbsp all-purpose flour

• 1 cup milk (dairy or warm plant-based milk)

• Pinch of nutmeg (optional)

• Salt and white pepper, to taste

Assembly & Topping

• 1 cup shredded mozzarella cheese

Step-by-Step Instructions

1. Bake the Potato Slices 🥔

Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper. Lightly spray the parchment paper with olive oil or avocado oil. Slice the peeled potatoes lengthwise into thin, uniform rounds or ovals. Arrange the potato slices in a single layer, spray the tops with oil, and season lightly with salt. Bake for 15–18 minutes until tender and lightly golden.

2. Cook the Beef Bolognese 🥩

In a skillet over medium-high heat, brown the ground beef along with the diced onion until the beef is cooked through and the onion is soft and translucent. Stir in the minced garlic and season with salt, pepper, and Italian seasoning. Pour in the bolognese sauce and let it simmer for 3–5 minutes until thick and fragrant.

3. Make the Runny Bechamel 🥛

In a small saucepan over medium heat, melt the butter. Whisk in the flour and cook for 1 minute to remove the raw flour taste. Slowly pour in the 1 cup of milk while whisking constantly to prevent lumps. Simmer gently for 2–3 minutes until smooth and slightly thickened, but still light and runny. Season with salt, pepper, and a pinch of nutmeg.

4. Layer the Lasagna 🍽️

In a baking dish, line the bottom with an overlapping layer of roasted potato slices. Top with a layer of the savory beef bolognese, then drizzle generously with the runny white bechamel. Repeat the layers (potatoes, beef, bechamel) until your ingredients are used up.

5. Bake to Bubbly Perfection 🧀

Generously cover the top layer with shredded mozzarella cheese. Bake at 375°F (190°C) for 18–20 minutes, then broil on high for 2–3 minutes until the cheese is melted, golden brown, and bubbling. Let rest for 10 minutes before slicing and serving.
