Step 1: In a large pot, bring generously salted water to a boil. Add the spaghetti and cook according to package instructions until al dente. Drain and set aside.
Step 2: In the same pot (or a large skillet), add the ground beef over medium heat. Cook until browned, breaking it apart with a spatula, about 5-7 minutes. Drain excess fat if necessary.
Step 3: Stir in the taco seasoning, ensuring the beef is well coated.
Step 4: Pour in the can of Rotel tomatoes (with juices) and stir to combine.
Step 5: Add the beef broth to the beef mixture and bring to a simmer. Allow it to cook for about 5 minutes to let the flavors meld.
Step 6: Add the cooked spaghetti to the pot, tossing gently to combine everything evenly. Cook for an additional 2-3 minutes until heated through.
Step 7: Serve your Taco Spaghetti hot, topped with your favorite toppings such as shredded cheese, sour cream, chopped cilantro, sliced jalapeños, or crushed tortilla chips for added crunch.
