🧾 Ingredients for King Ranch chicken casserole
This recipe sticks to affordable, easy-to-find ingredients that stretch well and feed a crowd. It's comfort food built for real kitchens, not a photoshoot.
- Corn tortillas - torn up, not fussy, adding the bulk like they always have
- Cooked chicken - leftovers, rotisserie, or whatever you've got that won't fight back
- Bell pepper - green if you're feeling traditional, any color if that's what's in the drawer
- Onion - because every good casserole starts with one quietly minding its business
- Butter - non-negotiable. This is not the time to worry about cholesterol - have you seen the rest of the ingredients
- Cream of chicken soup - the backbone, the binder, the reason it works
- Cream of mushroom soup - old-school, slightly mysterious, absolutely necessary
- Rotel tomatoes with chiles - the Tex-Mex heartbeat. Mild or original, your call
- Cheese - shredded, generous, and unapologetic
🔪 How to make authentic King Ranch chicken casserole
This is an easy, no-drama casserole-mix the creamy chicken filling with tortillas and cheese, and bake until bubbly. If you can tear and stir, you've already got the technique down pat.
- Heat the oven and grease your baking dish like you mean it. In a big skillet, melt the butter and sauté the onion and bell pepper until they smell good enough to distract anyone within shouting distance.
- Kill the heat and stir in the cream soups, Rotel, and cooked chicken. It should look rich, creamy, and slightly suspicious-in a good way.
- Layer it up: tortillas on the bottom, chicken mixture, cheese. Repeat until you run out of ingredients or patience, ending with cheese because we're civilized.
- Bake until bubbly and irresistible. Finish with a sprinkle of cilantro if you're feeling fancy, or skip it and proceed directly to gorging.
😱 What can go wrong (and how to fix it)
🌮 It's soupy instead of creamy
You stacked too fast or went light on tortillas. Use all the tortillas listed and let the casserole rest 5-10 minutes after baking so it can set before serving.
🌮 The tortillas turned to mush
That usually means flour tortillas or over-stirring. Stick with corn tortillas and layer-don't mix-so they hold their shape and soak up sauce like professionals.
🌮 It's dry around the edges
The casserole wasn't covered tightly enough. Spray the foil and seal it well for the first half of baking to trap moisture where it belongs.
🌮 The cheese stuck to the foil and ruined your mood
Always spray the foil with nonstick spray before covering. This is not optional. This is casserole law.
🌮 It tastes bland
Check your Rotel-mild is very mild. A pinch of salt, a little black pepper, or a splash of Rotel juice will wake things right up without changing the soul of the dish.
🌮 It fell apart when you served it
You skipped the rest time. Letting it sit a few minutes before cutting makes all the difference between "hearty casserole" and "Tex-Mex lava."
👩🍳 FAQs
Well, like so many things in my state there are a lot of tall tales! It's named after the biggest ranch in the Lone Star state (King Ranch is bigger than Rhode Island) and most likely was created in the 1940s or 50s but no one knows by whom. If you grew up in Texas you had it in the school cafeteria pretty much weekly.
If you can't find Rotel go ahead and use a 10 oz can of diced tomatoes (undrained) and a 4 oz can of green chiles (undrained). If the measurements are a little more don't sweat it.
No. So here's the deal. If you use flour tortillas they will break down in the sauce and became tasteless and gluey - something like that baby cereal that you try to get your baby to eat when they are tiny - only you end up wearing it instead. Please use corn tortillas.
📚 More Tex-Mex comfort food recipes
If casseroles and cozy dinners are your love language, you're in the right kitchen. Tamale pie brings that same Tex-Mex comfort with a cornmeal topping that means business, and one-pot taco spaghetti is a weeknight hero when you want bold flavor without a sink full of dishes. Both are easy, filling, and built for real life.
And when the craving shifts from spoonable to sliceable, homemade pizza is always a good idea. Taco pizza is fast, fun, and on the table in about 15 minutes-because some nights call for comfort food with a little attitude.
🏡 Bringing it home
This original King Ranch chicken casserole is the kind of old-school comfort food that's earned its place on the table-creamy, cheesy, mild enough for everyone, and never trying too hard. It's got that familiar Tex-Mex flavor that feels like home, with all the payoff of chicken enchiladas and none of the extra work.
This is a true mid-century classic, the sort of casserole that showed up in Junior League cookbooks, church kitchens, and family dinners on repeat.
Make it ahead, freeze it, pass it down, or keep it in your back pocket for nights when you need something dependable and deeply satisfying. Some recipes don't need improving-just remembering.

I am unable to pin the recipe. It is saying something about me not having authority For this domain. What am I doing wrong?
Marye says
Im not sure why it's doing that? I checked it and had others check it without a problem. You can pin it from here though -https://www.pinterest.com/pin/54746951710777206/
Greg says
I am going to freeze the King Ranch Chicken. Should I cook it prior to freezing, or freeze it before cooking.
Marye says
I usually cook it but you could do it either way.
Karen says
I made this for the first time yesterday. I made it per the recipe with no substitutions, but it was way too soupy at the end. I thought it would "gel" or "set up" and be a more scoopable casserole. What suggestions do you have? Thanks!
Marye says
I can't imagine it being soupy - I've never had that happen. I'm not sure what to tell you. If you diluted the soup that would make it soupy... but other than that I don't know.
Karli Siscoe says
My mom made this back in the 70’s and it called for tortilla chips not corn tortillas
Patricia A Jensen says
Quick question, Mayre. I want to make this for dinner tonight, but don't have the corn tortillas and really don't want to go to the store for one ingredient. Soooooo, what do you think if I substituted layers of Doritos Corn Chips? Since you probably won't be able to respond today (it's Sunday and hopefully you've taken the day off) I'm going to try it. Can't hurt and I'm sure it will be delicious. Thanks for sharing.

it will work! Emailing you.
