Southwestern Spaghetti is a hearty, yet simple casserole that’s sure to satisfy. Spaghetti in a taco seasoned sauce is topped with cheese and baked until golden brown. We’ve enjoyed this dish since I first made it in 2003.
- 16 oz spaghetti
- 1 lb ground beef
- 1 small onion, chopped
- 1 envelope taco seasoning
- 1 jar (26 oz) spaghetti sauce
- 1 can sliced mushrooms (I use the large size)
- 1 can (2⅕ oz) sliced olives
- 2 cups (8 oz) shredded sharp cheddar
- Cook spaghetti according to package directions. Meanwhile, in a large skillet, cook beef and onion over medium heat until meat is no longer pink; drain. Stir in the taco seasoning, spaghetti sauce, mushrooms and olives. Drain spaghetti; stir into the beef mixture.
- Transfer to a 13x9" baking dish; sprinkle with cheese. Bake uncovered at 350 degrees for 25-30 minutes.
- Dish may be served with lettuce, tomatoes, sour cream, and salsa.

If you like your food with just a bit of heat, I suggest adding a sprinkle of Mongolian Fire Oil to Southwestern Spaghetti before eating it. Mongolian Fire Oil gives this dish a small but pleasant amount of heat. We can’t find Mongolian Fire Oil and order it from Amazon. (The link I’ve provided is an affiliate link.)
