Classic Lasagna (Print Version)

# Ingredients:

01 - 60g butter.
02 - 4 cups milk.
03 - 2 cups gruyere or colby cheese, freshly grated.
04 - 1 tablespoon olive oil.
05 - 1 onion, finely chopped.
06 - 1 celery stick, finely diced.
07 - 1 medium carrot, finely diced.
08 - 2 garlic cloves, minced.
09 - 1kg ground beef.
10 - 800g crushed tomatoes.
11 - ¼ cup tomato paste.
12 - 1 cup pinot noir or dry red wine.
13 - 3 beef bouillon cubes.
14 - 2 bay leaves.
15 - ½ teaspoon each dried oregano and thyme.
16 - 2 teaspoons Worcestershire sauce.
17 - 1-2 teaspoons sugar (optional).
18 - ½ cup flour.
19 - Nutmeg, salt, and pepper to taste.
20 - 350g fresh lasagna sheets.
21 - 1½ cups mozzarella cheese, freshly grated.

# Instructions:

01 - In a pot, heat up oil and cook the onion, carrot, celery, and garlic until softened. Add the ground meat and brown it well.
02 - Add everything else related to the ragu, except sugar. Cover the pot and let it gently simmer for 1.5 to 2 hours. Remove the lid and simmer for another 30 minutes until the beef is tender.
03 - Start by making a roux. Melt butter and stir in the flour. Slowly pour in warmed milk while stirring to thicken. Mix in grated cheese and season lightly.
04 - Begin layering in your dish with lasagna sheets, followed by ragu and bechamel. Repeat this process three times, ending with a layer of lasagna and the rest of the bechamel sauce.
05 - Sprinkle mozzarella across the top. Bake at 350°F for 25 minutes until golden brown. Let it rest for about 5-10 minutes before slicing and serving.

# Notes:

01 - The ragu should have a rich and slightly saucy consistency.
02 - Freshly shredding cheese works best.
03 - You can prepare this ahead of time and keep it frozen.
