Heat the olive oil in a large 12-inch skillet over medium heat. You'll need a skillet with a lid for this one-pot meal.

Add the ground beef and diced onions to the hot skillet. Cook until the beef is no longer pink and the onions have softened and become translucent, breaking up the meat as it cooks.

Stir in the taco seasoning, Rotel tomatoes with their juice, uncooked spaghetti noodles, and water. Make sure the pasta is submerged in the liquid.

Bring the mixture to a boil over high heat. Once boiling, reduce the heat to low, cover the skillet with a lid, and let it simmer for about 15 minutes, or until the pasta is tender and most of the liquid has been absorbed.

Remove the skillet from the heat. Sprinkle half of the shredded cheddar cheese into the pan and stir it through to distribute it evenly throughout the hot pasta mixture. The residual heat will melt the cheese.

Top the dish with the remaining cheese and chopped cilantro. The heat will melt the top layer of cheese. Serve immediately while hot and cheese is melty.
