Mom's Spaghetti Bolognese

Bring a large pot of lightly salted water to a rolling boil.

Cook the spaghetti in the boiling water until cooked through yet firm to the bite, about 12 minutes; drain.

Heat the olive oil in a large pot over medium heat.

Cook the bacon in the oil until crisp, 8 to 10 minutes.

Stir the onion, celery, carrot, and oregano into the bacon; continue cooking until the vegetables begin to soften, another 8 to 10 minutes.

Add the garlic and cook until fragrant, about 2 minutes.

Crumble the ground beef into the vegetable mixture; cook and stir until the beef is completely cooked and no longer pink, 8 to 10 minutes.

Pour the balsamic vinegar over the ground beef mixture; allow to simmer until the liquid evaporates, about 5 minutes.

Stir the crushed tomatoes, tomato paste, and sugar into the ground beef mixture; bring the mixture to a boil, season with salt and black pepper, and remove from heat.

Stir the fresh basil into the mixture.

Ladle the sauce over the cooked spaghetti.

Top with Parmesan cheese to serve.
