🍽 Serves

🧀 Ingredients

For the Asparagus

• 1½ lb (700 g) fresh asparagus

• 1 tbsp olive oil

• Salt & black pepper

Trim woody ends. Keep spears whole for that pretty top layer.

For the Béchamel (White Sauce)

• 4 tbsp butter

• ¼ cup all-purpose flour

• 3 cups whole milk (warm)

• 2 cloves garlic, finely minced

• ¼ tsp nutmeg (optional but classic)

• Salt & white or black pepper, to taste

• ½ cup grated Parmesan cheese

For Assembly

• 9–12 lasagna sheets (oven-ready or pre-cooked)

• 2 cups shredded mozzarella (or Gruyère for extra flavor)

• Extra Parmesan for topping

• Fresh thyme or parsley (optional, for garnish)

🔥 Instructions

1. Prep the Asparagus

1. Preheat oven to 375°F / 190°C.

2. Toss asparagus with olive oil, salt, and pepper.

3. Roast on a baking sheet for 8–10 minutes, just until slightly tender (they’ll finish cooking in the oven).

4. Set aside.

2. Make the Béchamel Sauce

1. Melt butter in a saucepan over medium heat.

2. Whisk in flour and cook for 1–2 minutes (don’t let it brown).

3. Slowly whisk in warm milk, a little at a time.

4. Add garlic, nutmeg, salt, and pepper.

5. Simmer, whisking constantly, until thick and smooth (about 5 minutes).

6. Remove from heat and stir in Parmesan.

👉 Sauce should be creamy, not stiff—like pourable custard.

3. Assemble the Lasagna

1. Lightly butter a baking dish.

2. Spread a thin layer of béchamel on the bottom.

3. Add a layer of lasagna sheets.

4. Spoon béchamel over pasta, then sprinkle mozzarella.

5. Add a layer of asparagus (lay them neatly).

6. Repeat layers 2–3 times.

Final layer:

• Lasagna sheets

• Béchamel

• Mozzarella + Parmesan

• Arrange asparagus spears neatly on top (like in the photo)

4. Bake

1. Cover loosely with foil.

2. Bake for 30 minutes.

3. Remove foil and bake another 10–15 minutes until golden and bubbling.

4. Optional: Broil 2–3 minutes for extra browning.

5. Rest & Serve

• Let rest 10 minutes before slicing.

• Garnish with fresh thyme or parsley.

🌿 Variations & Upgrades

• Add protein: prosciutto, ham, or rotisserie chicken

• More depth: sautéed mushrooms or caramelized onions

• Extra luxe: swap mozzarella for Gruyère or fontina

• Lemon touch: add lemon zest to béchamel for brightness
