Ingredients:

• 1 tablespoon olive oil
• 1 onion, finely chopped
• 2 garlic cloves, minced
• 1 carrot, grated
• 1 celery stalk, finely chopped
• 1 pound (500g) ground beef
• 1/2 cup red wine (optional)
• 2 cans (14 oz each) crushed tomatoes
• 2 tablespoons tomato paste
• 1 teaspoon dried oregano
• 1 teaspoon dried basil
• Salt and black pepper to taste
• 1/2 cup whole milk
• 1 pound (450g) spaghetti
• Grated Parmesan cheese for serving
• Fresh basil or parsley for garnish

Instructions:

1. Sauté Vegetables: In a large skillet, heat olive oil over medium heat. Add chopped onion, minced garlic, grated carrot, and chopped celery. Sauté until the vegetables are softened.
2. Brown Ground Beef: Add ground beef to the skillet and cook until browned, breaking it apart with a spoon as it cooks.
3. Add Wine and Tomatoes: Pour in red wine (if using) and let it simmer for a few minutes. Add crushed tomatoes, tomato paste, dried oregano, dried basil, salt, and black pepper. Stir to combine.
4. Simmer: Reduce heat to low, cover, and let the sauce simmer for at least 1 hour. Stir occasionally to prevent sticking. If the sauce gets too thick, you can add a little water.
5. Finish the Sauce: Pour in the whole milk and simmer for an additional 15-20 minutes. Adjust seasoning if needed.
6. Cook Spaghetti: Cook the spaghetti according to package instructions until al dente. Drain and toss with a bit of olive oil to prevent sticking.
