I’ve been making this cheesy taco-flavored ground beef casserole for a long time.

And my whole family always requests that I make this for any big day where we all meet up to spend time together.

Mexican Trash Casserole

This Mexican white trash recipe has an amazing flavor that can be made with just a few common ingredients that most people already have in their house.

I highly recommend this Mexican twist on a delicious meal when you need a quick dinner tonight.

Or make it to store in the freezer for when you need something to grab on those busy weeknights.

The best part about this garbage casserole is that it’s the perfect quick meal when you still want something flavorful and filling but don’t have a ton of time on your hands.

Ingredients Needed

  • Ground beef – Swap for ground turkey or ground chicken breast. 
  • Taco seasoning – Use package taco seasoning from the store, or make homemade taco seasoning
  • Cheddar cheese – Use sharp cheddar or sub pepper jack or Monterey Jack. 
  • Condensed cheddar cheese soup – If you can’t find cheddar cheese soup, replace with cream of chicken soup or cream of onion.
  • Rotel tomatoes – Substitute with a can of diced tomatoes, tomato puree, and a can of green chilies instead.
  • Sour cream Swap out for cream cheese or greek yogurt as necessary.
  • Milk – The ¼ cup milk can be whole, skim, or non-fat, but I recommend whole milk.
  • Nacho cheese Doritos chips – I recommend a bag nacho Doritos, but you can use any flavor you like.
  • Pantry staples – Olive oil.

How to Make Mexican Trash Casserole Recipe

  1. Preheat oven to 350F. Spray the bottom of the casserole dish with nonstick spray. Set aside.
  2. In a large skillet, brown ground beef over medium-high heat until no longer pink. Drain excess fat. Add water and taco seasoning and cook for 1- 2 minutes.
  1. Add cheese soup, Rotel tomatoes, sour cream, and milk to skillet. Stir to combine. Add in half of shredded cheese. 
  2. In bottom layer of prepared quart casserole dish, place half of crushed chips.
  1. Layer half of your taco meat mixture on top. Add the rest of the Doritos.
  2. Cover with a top layer of the remaining meat. Finish off with even more shredded cheese.
  3. Bake for 30 minutes or until bubbly and cheese is melted.
  4. Remove and garnish with parsley or green onion. Enjoy your warm taco casserole!

To heat up those leftovers from last night, move your mixture into an oven safe container, and bake at 350F until it’s thoroughly heated (165F internal temperature).

What To Serve With Mexican Trash Casserole 

Since this is a delicious warm casserole, I would balance it out with a large bowl of salad and a side of refried beans or black beans and rice.

If you’re feeling adventurous, you can also create your own Mexican street corn to go along with the flavor palate of this delicious dip style casserole.

How Can I Store My Leftovers?

The most beautiful thing about this Mexican Trash Casserole is how easy it is to store and save for later!

The best way to store your leftovers so you can have them again the next day is in an airtight container in the fridge.

Transfer your casserole to another sealable container, or cover tightly with aluminum foil. This meal will stay good in the fridge for up to 3 days, so you have a little bit of time to eat it. 

Or microwave, heating it up in 2 – 3 minute intervals until it’s completely warm.

Different Variations To Try

Since this casserole is a take on a warm bean dip, there are a lot of different things that you can try to spice it up, especially if you plan on making this meal often.

I recommend changing out the beef for chicken, layering half of the chicken mixture on top of your Doritos, before covering with another chip layer.

You can then add on the rest of the chicken mixture, and cook the same way that you would with the beef to create a delicious Dorito chicken casserole!

Substitute the Doritos in this recipe for regular tortilla chips, since these are what would traditionally be served if this was made as a Mexican dip instead of casserole style.

This is also a great solution if you have someone in the family who is gluten free, because you can use corn based tortilla chips instead.
