Lasagne al Forno (alla Bolognese)

Classic Italian baked lasagne with rich, slow-simmered meat ragù, creamy béchamel, and bubbly golden cheese layers.

Ingredients

• 2 tbsp olive oil
• 1 onion, finely chopped
• 2 carrots, finely chopped
• 2 celery sticks, finely chopped
• 4 garlic cloves, minced
• 800 g (1.75 lb) ground beef (or half beef/half pork if you have it)
• 2 tbsp tomato paste
• 800 g (28 oz) canned crushed tomatoes (passata-style is ideal)
• 250 ml (1 cup) beef stock or water
• 125 ml (1/2 cup) milk
• 2 bay leaves (optional)
• 1 tsp dried oregano (optional)
• 1 1/2 tsp salt, plus more to taste
• 1/2 tsp black pepper
• 80 g (6 tbsp) butter
• 80 g (2/3 cup) all-purpose flour
• 1 L (4 cups) milk, warmed (microwave or stovetop)
• 1 tsp salt
• 1/4 tsp black pepper
• Pinch of nutmeg (optional but classic)
• 375–450 g lasagne sheets (dried no-boil or fresh)
• 150 g (1 1/2 cups) grated mozzarella
• 80 g (3/4 cup) finely grated Parmesan (or Grana Padano)
• Olive oil, for greasing the dish

Method

• 1

  Step 1: Build the ragù base

  Heat olive oil in a large pot over medium heat. Add onion, carrot, and celery with a pinch of salt. Cook, stirring, until soft and sweet (not browned), about 8–10 minutes. Add garlic and cook until fragrant, 30 seconds.

  Step 2: Brown the meat properly

  Increase heat to medium-high. Add the ground meat and break it up. Cook until you see browning on the bottom and most liquid has evaporated, 8–10 minutes. (This step is where big flavor comes from—don’t rush it.)

  Step 3: Tomato + slow simmer

  Stir in tomato paste and cook 1 minute. Add crushed tomatoes, stock (or water), milk, bay leaves, oregano (if using), salt and pepper. Bring to a gentle simmer, then reduce to low. Cook uncovered 60–75 minutes, stirring occasionally, until thick and rich—when you drag a spoon through, it should leave a trail that slowly fills in. Taste and adjust seasoning. Remove bay leaves.

  Step 4: Make béchamel (lump-free)

  Melt butter in a saucepan over medium heat. Add flour and whisk for 1–2 minutes until it smells slightly nutty (but stays pale). Gradually whisk in warm milk in splashes, smoothing out lumps as you go. Simmer gently, whisking, until thick enough to coat the back of a spoon, about 5–7 minutes. Season with salt, pepper, and nutmeg.

  Step 5: Prep for layering

  Preheat oven to **180°C / 350°F (160°C fan)**. Lightly oil a **33 x 23 cm / 13 x 9 in** baking dish. If using dried “no-boil” sheets, ensure your sauces are a bit looser (béchamel should pour; ragù should be saucy, not dry).

  Step 6: Assemble the lasagne

  Spread a thin layer of ragù on the base (prevents sticking). Layer in this order, repeating **4–5 layers**:

  Step 7: Bake until bubbly and golden

  Cover loosely with foil (so it doesn’t stick to cheese). Bake **30 minutes**, then remove foil and bake **20–25 minutes** more until deep golden on top and bubbling around the edges. For extra browning, grill/broil 1–2 minutes—watch closely.

  Step 8: Rest, then slice cleanly

  Rest **20–30 minutes** before cutting. This sets the layers so you get neat slices instead of a lava slide.

Tips

• **Kid-friendly vs grown-up**: Keep it classic (no heat). If adults want spice, add chili flakes to their portion at the table—don’t bake it into the whole tray.
• **No-boil sheet tip**: Make sure every pasta corner is covered with sauce (dry corners stay crunchy).
• **Make-ahead**: Assemble up to 24 hours ahead and refrigerate. Bake straight from fridge, adding **10–15 minutes** covered time.
• **Freezing**: Freeze baked (best) or unbaked, tightly wrapped. Thaw overnight, then bake until piping hot throughout.
• **Serve with**: A simple green salad with olive oil and vinegar, or steamed green beans—something fresh to cut the richness.
