Preparation Steps

• Heat olive oil in a large pot over medium heat. Add the diced onion and minced garlic, cooking until the onion is translucent.
• Add ground beef or Italian sausage to the pot. Cook until browned and no longer pink, breaking it up as it cooks.
• Stir in the marinara sauce, water, Italian seasoning, and red pepper flakes. Bring to a simmer.
• Add the uncooked penne pasta, ensuring it's covered by the sauce. Reduce heat to low and cover the pot. Simmer for 15-20 minutes, stirring occasionally, until pasta is cooked to your liking.
• Stir in the mozzarella cheese and sliced pepperoni. Cook until the cheese is melted.
• Serve warm, garnished with grated Parmesan cheese and chopped fresh basil.
