King Ranch Beef Casserole
This King Ranch Beef Casserole was such a hit at my house! Greg, Skyler and I pretty much took the whole thing down in one sitting. I love how the Rotel adds so much flavor without making it too spicy, and the taco shells give it the best little crunch mixed in with all the melty cheese. This is a fun change up from the original king ranch chicken we’re used to. Enjoy! (Recipe adapted from King Ranch Beef Casserole).
Ingredients/Substitution Ideas
- Lean ground beef–or ground turkey, pork
- Onion–yellow or white
- Green bell pepper
- Kosher salt
- Black pepper
- Garlic powder
- Chili powder
- Cumin
- Rotel
- Cream of chicken–or cream of mushroom soup
- Crispy taco shells–or tortilla chips
- Cheddar cheese–or a mexican blend, colby jack
Steps
Heat oven to 350° F. Heat an oven safe skillet (I used my cast iron skillet*) over medium high heat. Add in the beef and break it up. Add in the onions and green pepper. Brown for 5 minutes. Drain off excess grease.

Stir in the salt, pepper, garlic powder, chili powder and cumin to season the beef.
Turn heat to low. Stir in the Rotel and cream of chicken.

Break up the taco shells and stir them in along with 1 cup of the cheese.

Sprinkle the remaining cheese on top.

Bake for 25 minutes. Serve and enjoy!

Notes/Tips
- Serve with shredded lettuce, seasoned black beans and sliced avocados.
- This can be gluten free if you use gluten free cream of chicken soup (Campbell’s makes it now) and gluten free taco shells.
- I used my cast iron skillet*. If you don’t have an oven safe skillet you can transfer the mixture from a pan to a 9×9 inch baking dish.
- Store leftovers in an airtight container* in the refrigerator for up to 4 days or in the freezer for up to 3 months.
- Other recipes you can make with green bell pepper are Amish Hamburger Casserole and Pennsylvania Chicken Casserole.

What could you use instead of cream of chicken soup. I can’t use canned soups.
I’ve used cream cheese with chicken Better than bullion. I’m not a fan of condensed soups either. If you’re dairy free you can make a thick chicken gravy with the bullion and a simple roux. Hope this helps!!!
I love these ideas. thanks CJ!
