For Bolognese Sauce
Heat 1 tablespoon of olive oil in a heavy-bottomed pot over medium heat (I used a dutch oven)
Add the onions and carrots. Season with salt and cook for 2-3 minutes or until the onions have softened
Add oregano, basil, and garlic. Cook for 1-2 minutes
Add the beef and increase the heat
Cook the beef until browned, make sure you break up the beef into small pieces. Season with salt and pepper
Drain the excess liquid and add the wine. Cook until the wine has reduced by half.
Add the bay leaves, tomato paste, water, parmesan cheese rind, and the crushed tomatoes (or prepared tomato sauce). Mix well
When sauce starts to boil, reduce the heat to simmer and cook for 1-2 hours partially covered
Check it every once in a while to make sure the sauce hasn't dried. If that happens simply add more liquid.
Check for seasoning and serve with hot pasta and parmesan cheese
For Bechamel Sauce
Warm the milk in the microwave
In a saucepan, melt the butter over medium-low heat
When the butter is melted, add the flour and whisk until incorporated and the flour is cooked (about 45 seconds to 1 minute)
Add the warm milk and whisk vigorously to avoid lumps
Keep whisking until the sauce starts getting thick and creamy.
When it boils, remove from heat and add the cheese, salt, pepper, and nutmeg. Mix until combined
