Creating this Cheesy Taco Salsa Spaghetti Bake involves several straightforward steps that will guide you effortlessly:

1. Preheat the Oven: Begin by preheating your oven to 375°F (190°C).
2. Cook Spaghetti: In a large pot of salted boiling water, cook the spaghetti according to package instructions until al dente. Drain and set aside.
3. Prepare Meat: In a large skillet over medium heat, brown the ground beef or turkey until fully cooked. Drain any excess grease.
4. Season Meat: Add the taco seasoning to the cooked meat, stirring well. Follow the packet’s instructions, usually adding water or beef broth if required. Simmer for about 5 minutes.
5. Combine Ingredients: In a large bowl, mix the cooked spaghetti, seasoned meat, salsa, black beans, and corn. Stir to combine all ingredients thoroughly.
6. Assemble the Bake: Spread half of the spaghetti mixture into a 9×13-inch baking dish. Top with half of the shredded cheese.
7. Layer Again: Add the remaining spaghetti mixture on top, followed by the sour cream, and then top with the remaining cheese.
8. Bake: Place the baking dish in the preheated oven and bake for 30–35 minutes or until heated through and the cheese is bubbly and golden.
9. Cool: Remove the dish from the oven and let it cool for about 5 minutes before serving.
