Pasta Bolognese

Heat olive oil in a large pan over medium heat.

Add chopped onion, carrot, and celery; sauté until softened.

Stir in minced garlic and cook for another minute.

Add ground beef and cook until browned, breaking it up with a spoon.

Pour in red wine and let it simmer until reduced by half.

Stir in canned tomatoes and tomato paste; season with salt, pepper, and oregano.

Reduce heat and let the sauce simmer for about 30 minutes, stirring occasionally.

Meanwhile, cook spaghetti according to package instructions until al dente; drain.

Serve the spaghetti topped with Bolognese sauce, garnished with fresh basil and grated Parmesan cheese.
