Cook bacon (or pancetta) in a large 6 quart Dutch oven medium-high heat until crisp. Remove to paper towels to drain, then crumble. Reserve 2-3 Tbsp drippings in pot and freeze or discard the rest. (You can skip this step and begin with olive oil.)
Add beef and sausage, cooking over medium-high heat for 6-8 minutes or until browned and no pink remains, stir to crumble. Use a slotted spoon to remove beef-pork mixture from pan to a plate to keep warm.
Over medium-high heat add carrot, celery and onion to the drippings left in pan. Add additional olive oil, if needed. Sauté for 4-6 minutes, stirring occasionally, or until softened and beginning to brown. Scrape any brown bits from the bottom of the pot.
To the veggies add add meat mixture, diced tomatoes, tomato puree, beef stock, tomato paste, salt, Italian seasoning, onion powder, pepper, red pepper flakes and bay leaves; bring to a boil. (Pro Tip: You can replace 1/2 cup stock with wine, if desired) Cover with lid, reduce heat to low, and simmer for 1 hour, stirring occasionally.
Uncover and remove bay leaves, and discard. Stir in heavy cream. Mix well.
Thicken further with additional tomato paste 1 Tbsp at a time. Repeat until desired consistency is reached.
Serve immediately ladled over cooked spaghetti, rigatoni, pappardelle, or tagliatelle. Top with grated Parmesan cheese and a sprinkling of parsley.
