Cook the Red Sauce:

• Heat olive oil in a large skillet over medium heat. Add the chopped onion and green bell pepper and sauté for 2-3 minutes, until softened.
• Add the minced garlic and cook for another 30 seconds.
• Add the ground beef to the skillet, season with salt, pepper, and Italian seasoning. Cook until the beef is browned and fully cooked, about 5-7 minutes.
• Pour in the spaghetti sauce and stir to combine. Reduce the heat and let it simmer while you cook the pasta.

Cook the Pasta:

• Bring a large pot of salted water to a boil. Add the spaghetti and cook according to the package instructions until al dente, about 9-10 minutes. Drain and set aside.

Make the Alfredo Sauce:

• In a separate saucepan, melt the butter over medium heat. Add the minced garlic and cook for 1-2 minutes until fragrant.
• Stir in the flour and cook for 1 minute, stirring constantly.
• Slowly whisk in the heavy cream, ensuring no lumps form. Bring the mixture to a simmer, then stir in the Parmesan and mozzarella cheeses. Cook until the sauce is smooth and creamy, about 3-4 minutes. Season with salt and pepper to taste.

Combine the Sauce and Pasta:

• Add the cooked spaghetti to the skillet with the red sauce and toss to coat.
• Pour the Alfredo sauce over the pasta and toss everything together until well mixed.

Serve:

• Serve the TikTok Spaghetti hot, and garnish with extra Parmesan or fresh herbs, if desired.
