In a large pot or Dutch oven over medium heat, cook the ground beef until browned and no longer pink. Drain any excess fat.
1 pound ground beef
Add the onion, garlic, and taco seasoning to the beef. Cook for 1–2 minutes, stirring often, until fragrant. Stir in the Rotel, tomato sauce, and beef broth. Mix well to combine.
1 small onion, 2 cloves garlic, 1 packet taco seasoning, 1 cup Rotel diced tomatoes with green chilies, 1 cup tomato sauce, 1½ cups beef broth
Break the spaghetti noodles in half and add them to the pot, ensuring they are fully submerged in the liquid.
12 ounces spaghetti noodles
Bring to a boil, then reduce heat to low. Cover and simmer for 15–17 minutes, stirring occasionally, until the pasta is tender and the sauce has thickened.
Turn off the heat. Stir in half of the shredded cheese until melted. Sprinkle the remaining cheese over the top, cover, and let it rest for a few minutes until gooey.
2 cups Monterey Jack cheese
Garnish with fresh cilantro and green onions before serving. Enjoy warm.
