Mexican Spaghetti Casserole Ingredients

ground beef


taco seasoning (I always keep this on hand!)

tomato sauce

diced mild tomatoes and green chiles

spaghetti pasta

shredded cheddar and Monterey Jack cheese

fresh cilantro

spaghetti with cheese in a bowl

Step-by-Step Instructions

In a large skillet, you’ll want to brown your hamburger onion. Be sure to drain any excess fat!

Next, stir in the taco seasoning, tomato sauce, RO-TEL (diced tomatoes and green chiles) and the water. Bring this mixture to a boil.

Then, break the spaghetti in half and add to the sauce and stir. Reduce the heat, cover and allow to simmer for 10 to 15 minutes, or to desired tenderness.

Sprinkle the cheese over the top. Cover until cheese is melted.

Garnish with plenty of fresh cilantro, if you like it!

  1. I made this last night. Super quick and easy. And oh SO delicious! Thank you so much, Crissy. This will definitely be added to my monthly rotation.

  2. Love it and did add salsa and a scoop of sour cream; yum!!! Did make jalapeño cornbread and corn on the cob… so very satisfying. Also I added half  hot pork sausage to the meat.  Oh my oh my, really god and thanks so much

  3. I just made this for the first time and it was delicious!  I used impossible burger since I am working on my cholesterol level.  I would definitely make it again and I am sure it tastes even better with real beef.

  4. Looks delicious I’m definitely making it.

  5. Why does the skillet need to be oven safe? I don’t see where it’s going in the oven.

  6. I’m very disappointed. I’ve been cooking the noodles for 36 minutes and they are still not done. The sauce was so good, so that really sucks. Waste of time!

  7. Million dollar fudge
