Bring a large pot of salted water to a boil. Add the spaghetti noodles and cook according to the package directions until al dente. Drain, then set aside.
8 oz spaghetti pasta
In a large skillet or pot (I use the same Dutch oven I used to cook the pasta) over medium heat, add your ground beef, turkey, or chicken. Break it up with a spoon and cook until browned and fully cooked through. Drain off any excess grease.
1 pound ground beef
Add diced onions, green peppers, and minced garlic to the skillet with the meat. Cook for about 3–4 minutes, or until the veggies are softened and fragrant.
½ cup chopped onion, ½ cup chopped green peppers, 4 garlic cloves Minced
Sprinkle in the Italian seasoning, salt, and pepper to taste. Stir to coat the meat and veggies evenly.
1 teaspoon Italian Seasoning, salt and pepper to taste
Pour in the crushed tomatoes and stir everything together. Add in the Cajun or Creole Seasoning, Italian Seasoning, oregano, salt, pepper, and sugar (start with 2 teaspoons) to balance out the acidity. Taste and adjust as needed. Add more Cajun seasoning if you want a little heat, or more sugar for balance.
28 oz canned crushed tomatoes, ¼ teaspoon ground oregano, 1 teaspoon Italian Seasoning, 1 teaspoon Cajun Seasoning, ¼ cup sugar or sweetener, salt and pepper to taste
Add the cooked spaghetti to the sauce. Toss everything together until the noodles are coated and the meat is well distributed. If the sauce is too thick, splash in a little water to loosen it up.
Lower the heat to low and let the sauce simmer for 15-20 minutes, stirring occasionally. This gives the flavors time to come together and thicken slightly.
