Southwestern Spaghetti

Southwestern Spaghetti - Spaghetti with a kick!  #spaghetti #southwesternrecipe #spaghettirecipe  #pasta

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.

Southwestern Spaghetti
Serves: 8
  • 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
  1. 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.
  2. Transfer to a 13x9" baking dish; sprinkle with cheese. Bake uncovered at 350 degrees for 25-30 minutes.
  3. 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.)

  5. Oh, that sounds really good, except for the olive part. However, my husband loves them, so I could just put them on half of it. Yummy.
