MAKE THE PASTA SAUCE
To a saucepan over medium high heat, heat the olive oil and butter. Then add the garlic and saute for 1 minute.
Add the meat along with the red pepper flakes, Italian seasoning, oregano, basil, black pepper, and salt. Break it up as it cooks and browns, about 6 to 7 minutes. If using onions, add it in along with the ground beef.
Pour in the marinara sauce and mix it all together. Let it simmer for about 30 minutes.
Now add the splash of heavy cream along with the parmesan and parsley. Mix everything and taste. Adjust any seasoning to your liking.
COOK THE PASTA
Bring a large pot of water to a boil about 15 minutes before the sauce is done. Salt the water and bring to a boil again.
Add the pasta and cook according to package directions to al dente or a minute past al dente depending how you like it. Make sure to stir frequently so the noodles don't stick together.
Once done, save some of the pasta water and transfer the noodles to the sauce with a little bit of pasta water (1/4 to 1/2 cup). Mix it all together.
Add more parmesan on top and some fresh basil or parsley and enjoy!
