Butter, olive oil, onion, celery, carrots, beef, sausage, garlic, salt, red pepper, sugar, pepper, Italian seasoning, crushed tomatoes, tomato sauce, beef broth, milk.
1
Add the butter and olive oil to a large saucepan and melt over medium-high heat.
2
Place the chopped onions, celery, and carrots. Sauté for 2 minutes.
3
Add the minced garlic, ground beef, and Italian sausage to the vegetables and cook until the meat is no longer pink, about 5 minutes.
4
Add the salt, pepper, Italian seasoning, and red pepper flakes to the meat and stir to combine.
5
Then stir in the milk and allow the mixture to simmer for about 5 minutes.
6
Add the crushed tomatoes, tomato sauce, tomato paste, and beef broth. Bring the mixture to a boil, then lower the heat and simmer for 15 minutes.
7
While the Bolognese sauce is simmering, prepare the spaghetti noodles according to the package directions.
8
Serve! I like to mix some of the sauce with the spaghetti to keep the noodles from drying out, then serve more sauce on top.
