In the pan with the beef drippings, melt 3 tablespoons of butter and add a couple tablespoons of olive oil.
Cook the onion for a 3-4 minutes until it's translucent.
Add the rest of the ingredients and turn the stove on low.
Cover the pot and cook until the pasta is tender. This usually takes about 20-30 minutes. Don't let it boil because the noodles will get too sticky. Just be patient. They'll be soft before you know it.
