The Forget Sugar Friday recipe for king ranch chicken is keto-friendly.

Where Did King Ranch Chicken Come From?

I won’t lie; as a northerner, when I first heard the term “King Ranch Casserole,” I thought it was a recipe with ranch dressing. 😉

The truth is, no one really knows how the recipe, popular in Texas, came to be called King Ranch Casserole, or where it originated. An easy assumption is that it was named after the King Ranch in Kingsville, Texas, but that theory has been debunked. It has been made especially popular by The Pioneer Woman, but she didn’t have anything to do with the creation of the recipe either. We may never know!

    • Hi Debbie! I recommend anything with 1g sugar or less per serving. That is most salsas on the market, but not all. For a completely sugar-free option, I recommend Frontera and Clint’s brands.

  • Guess what we’re having for dinner tonight now?! I can not wait! The Siete corn tortillas are missing in action in my area. I plan to use my Joseph’s Lavash Bread that I normally make my keto friendly chips out of instead. Pre-keto, my King Ranch Casserole used an entire bag of Doritos…..and I wondered why I could never lose any weight 🤣. I’m sure I’ll be back to rate this a “5 Star Keeper” recipe. You always share such fantastic recipes. Thank you!!

    • Hi Tracy, Thank you so much for the kind comment! 🙂 I hope you enjoy the recipe, and thank you in advance for committing to coming back and leaving a rating. Those ratings really help out my blog and fellow readers! The recipe may not compare 100% to the Doritos version, but hopefully it will come close! 😉

        As predicted, it was soooo good! Even my non-keto Husband approved. I did add my own homemade salsa with extra roasted green chiles for a little kick. All the ingredient portions were spot on for a fast keto dinner. Thanks again!

  • I made this for my husband and I . We loved it and we had no leftovers. Thank you for the recipe. Easy to make.

  • 5 stars
    I have been on a low carb diet for 7 months and have lost 40 pounds. My husband is not on this with me. But he will eat what i make. I either get, ‘loose this recipe’, or ‘better save this one’. I made this casserole today and he said, ‘are you not doing low carb any more’? He really liked this one. I thought it was delicious.

    • Hi Jan! First – CONGRATS on the 40lb weight loss! 🎉 That is fantastic! And second, thank you so much for sharing! I’m thrilled that you liked the recipe *and* it’s husband-approved. 😁

  • Your instructions call out cream cheese, but the actual recipe to print calls for sour cream. Are they interchangeable?

    • Hi Kathy, My apologies for missing your comment and for the error! You should use sour cream as in the recipe card; I will update the post to reflect that. Thank you!

    My husband and I just tried this tonight for dinner. So delicious!!! I’ve got a 2nd batch in the oven so we can have it for lunches this week. Thanks for sharing the recipe!!

    Keto King Ranch Casserole makes a great meal. It is super easy to put together and the flavors are fantastic! I served it to my family this past weekend and they all loved it. I like Keto friendly recipes that I can eat and also serve to my family who are not on a Keto diet.

  • 5 stars
    This recipe is Amazing!! I loved it very much. I put the leftovers in single serving freezer bags for later! I will definitely make it again!!

    • Hi Ashli! I have been meaning to try this recipe with the Mission low carb tortillas but haven’t had a chance yet. I think they will work, but they’re softer than the Siete tortilla, so I recommend crisping them up on a dry, heated skillet first.

  • 5 stars
    I am from Texas and all my life ate King Ranch casserole. Instead of salsa we always used a can of Rotel. I am thinking that may be a Texas thing. so if you don’t have Rotel you can sub a can of diced tomatoes and a can or jar of hatch green chili peppers.

  • 5 stars
    This recipe was incredibly amazing and we loved it. Six servings would be child sized servings. Three adults ate the whole thing and relished every bite.

  • 5 stars
    Easy to make and very tasty. I added a can of green chilies to it. I also doubled the recipe for my 4, they are big eaters and there was nothing left! They had no clue it was low carb.

    I made this tonight and it was delicious!! My whole family loved it! It was easy to make & had so much flavor!! I have type 2 diabetes & I’m always looking for a low carb meals that will satisfy the whole fam. This is going on my favorites folder!! Thanks for sharing!

  • 5 stars
    This is delicious. My husband and I are both diabetic so try to do low carb when we can but the whole family loved this. I have it in my favorites. I double the recipe and have 5 people and we never have leftovers.

  • 5 stars
    My whole family really enjoyed it and that is saying a lot with how picky we can be. I’m doubling the portions next time to have left overs. 😊

    • Thank you so much for the review, Christie! I’m thrilled to hear that your whole family enjoyed the recipe! 😊

  • 5 stars
    This was excellent! Made homemade tortilla chips from Mission Carb Balanced tortillas, and added some garlic powder, onion powder, cumin, smoked paprika and cayenne pepper to taste (didn’t measure). Served with chopped lettuce, guacamole & salsa. Made a really great low carb meal. A winner in our house!

  • 3 stars
    Came out very tasty but doesn’t set up like a casserole, like I assumed it would. It’s very runny. I would use it more as a dip with low carb chips next time. because it’s not solid, portions do seem small. still good tho!!

    • Hi Rhonda, Thank you for the feedback! I’m so sorry to hear it didn’t set up for you. I’m glad you were still able to enjoy it!

  • 5 stars
    This was really delicious. I couldn’t find the almond flour tortillas so just used my low-carb Don Poncho ones. I did add 1tsp of ranch seasoning but everything else was the same. My husband and daughter loved it too! Served it with fresh avocado slices. Thank you for a great recipe!

    • Hi Ang, thank you so much for your review! I love the idea of adding ranch seasoning – I’ll definitely have to try that!
