Food.com offers a spaghetti recipe that serves between 10 and 14 people. To make spaghetti for 50 people, you must multiply the serving size by 5. In this case, required ingredients for a group of 50 include 10 pounds of Italian sausage with the casings removed, five small chopped onions, 15 to 20 minced garlic cloves, five 28-ounce cans of diced tomatoes and 10 6-ounce cans of tomato paste.
Additionally, you need 10 15-ounce cans of tomato sauce, 10 cups of water, 15 teaspoons of basil, 10 teaspoons of dried parsley flakes and 7 1/2 teaspoons of brown sugar along with 5 teaspoons of salt, 1 1/4 to 2 1/2 teaspoons of crushed red paper flakes and 1 1/4 teaspoons of ground black pepper. Lastly, you need 1 1/4 cup of red wine, preferably a Cabernet, and 5 pounds of thin spaghetti.
Brown the Italian sausage in a large stockpot, breaking the sausage into smaller pieces while stirring. Combine the onions and continue to cook the sausage until the onions become soft. Proceed to add the garlic cloves, diced tomatoes, tomato paste and tomato sauce along with the water. If the ingredients cannot fit into the stockpot, separate them into two separate pots.
Add the basil, parsley, brown sugar, salt, red pepper and black pepper, then simmer while stirring the sauce. Add the red wine, and stir frequently for a minimum of one hour. The longer the simmer, the better the sauce turns out. Cook the spaghetti in batches, according to the directions on the package, and then pour the sauce over the drained noodles. Sprinkle the finished recipe with Parmesan cheese.
