Prepare the Red Sauce:

• In a large skillet or pan, heat the olive oil over medium heat. Add the chopped onion, green bell pepper, and minced garlic. Sauté for 3-4 minutes until the vegetables are softened.
• Add the ground beef to the pan, breaking it up as it cooks. Cook for 6-7 minutes, or until the beef is browned.
• Season with salt, black pepper, and Italian seasoning, then stir in the spaghetti sauce. Simmer the sauce for 10-15 minutes, allowing the flavors to meld. Set aside.

Cook the Spaghetti:

• While the red sauce is simmering, bring a large pot of water to a boil. Add 1 tablespoon of salt to the water, then cook the spaghetti according to package instructions (usually about 8-10 minutes for al dente).
• Drain the spaghetti and set aside, keeping it warm.

Make the Alfredo Sauce:

• In a separate pan, melt the butter over medium heat. Add the minced garlic and sauté for 1-2 minutes, until fragrant.
• Sprinkle the flour over the melted butter, stirring to create a roux. Cook for 1-2 minutes, until the flour is slightly golden.
• Gradually add the heavy cream, stirring constantly to avoid lumps. Bring the mixture to a simmer and cook for 3-5 minutes until it thickens.
• Stir in the Parmesan and mozzarella cheese until melted and smooth. Season with a pinch of salt and pepper.

Assemble the Dish:

• In a large mixing bowl or serving dish, combine the cooked spaghetti and red sauce, tossing to coat the pasta.
• Pour the Alfredo sauce over the top of the spaghetti and gently mix to combine. If desired, you can reserve some Alfredo sauce to drizzle over the top before serving.

Serve:

• Serve the TikTok Spaghetti warm with extra Parmesan cheese on top for garnish, and enjoy the creamy, cheesy goodness!
