Prepare to indulge in a rich, creamy, and satisfying casserole that doesn’t compromise on flavor or your dietary goals.
What is King Ranch Chicken Casserole?
King Ranch chicken casserole is a legendary dish, deeply rooted in Southwestern cuisine, particularly in Texas. While its exact origins are shrouded in mystery—despite its name suggesting a connection to the famous King Ranch, the largest ranch in the United States, which is actually larger than the state of Rhode Island!—its popularity is undeniable. Many tales circulate, but no one at the King Ranch can definitively claim the recipe as their own. Regardless of its true genesis, this casserole has earned a cherished spot in countless American kitchens.
Traditionally, King Ranch chicken casserole features layers of corn tortillas, tender chicken, and a creamy sauce made from canned cream soups, often spiced with Rotel (diced tomatoes and green chilies), bell peppers, and onions, all topped with melted cheese. It’s a dish known for its hearty, comforting qualities and its distinctive Southwestern flair. Our version honors this rich heritage while cleverly adapting it to fit a low-carb and keto lifestyle without sacrificing any of that signature taste.
Making Your King Ranch Casserole Keto-Friendly
The beauty of this recipe lies in its smart substitutions that make it perfectly suitable for a ketogenic diet. The most significant changes occur in the creamy base and the tortilla layers. Instead of relying on carb-heavy canned cream soups, which often contain thickeners and starches that can spike carb counts, we create a rich and luscious sauce using heavy whipping cream. This not only keeps the carb count low but also adds an incredibly decadent texture and depth of flavor that is far superior to its canned counterparts.
The other crucial adaptation involves the tortillas. Traditional King Ranch chicken uses corn tortillas, which are high in carbohydrates. To keep this recipe keto, we opt for low-carb tortillas. These readily available alternatives provide the necessary structure and chewiness without derailing your macros. You can easily find them in most grocery stores, or if you’re feeling adventurous, you can even make your own. I have a fantastic recipe for low-carb tortillas that you can find within my Keto Mexican Pizza recipe. These two simple swaps—heavy cream for cream soup and low-carb tortillas for corn tortillas—are the secret to transforming a classic comfort food into a keto masterpiece.
Essential Ingredients for Your Keto King Ranch Chicken
Crafting this incredible casserole begins with selecting fresh, high-quality ingredients. Each component plays a vital role in building the layers of flavor and texture that make this dish so special.
- Low-Carb Tortillas: As discussed, these are your foundation. Pre-made ones offer incredible convenience, saving you time and effort. Cut them into pieces to fit your baking dish.
- Shredded Chicken: This is the star protein. For ultimate convenience, a store-bought rotisserie chicken is a game-changer. Simply shred the cooked chicken, and you’re good to go. Alternatively, you can boil or bake chicken breasts and then shred them yourself.
- Medium Onion & Red Bell Pepper: These aromatic vegetables provide essential flavor and a pleasant texture. Chopping them finely ensures they blend seamlessly into the creamy sauce.
- Heavy Whipping Cream & Chicken Broth: Together, these form the rich, creamy base of the casserole, offering a luxurious mouthfeel and savory depth.
- Chicken Bouillon Powder: This ingredient amplifies the chicken flavor in the sauce, adding an extra layer of umami. A bouillon cube works just as well.
- Rotel (Drained): A quintessential King Ranch ingredient! These diced tomatoes and green chilies bring a distinctive Southwestern spice and a hint of tang to the dish. Draining them is crucial to prevent the casserole from becoming watery.
- Salt and Pepper: Essential seasonings to enhance all the other flavors. Adjust to your personal taste.
- Green Onions: These add a fresh, mild onion flavor and a pop of color, both mixed into the casserole and used as a garnish.
- Colby Jack Cheese: This cheese melts beautifully and provides a creamy, mild flavor that complements the other ingredients perfectly. Feel free to experiment with other melty cheeses like cheddar or Monterey Jack.
- Butter: Used to sauté the vegetables, it adds richness and helps create the flavorful base for the sauce.
The Magic of Ro-Tel Tomatoes
No King Ranch chicken casserole would be complete without the vibrant kick of Ro-Tel tomatoes. This blend of diced tomatoes and green chilies is a pantry staple for anyone who enjoys Southwestern and Tex-Mex flavors, and for good reason. It’s incredibly versatile, adds a wonderful layer of spice and tang, and is naturally low-carb, making it perfect for keto recipes.
I always keep several cans of Ro-Tel on hand because it’s a quick and easy way to infuse flavor into so many dishes. From my savory Keto Queso Dip to a comforting Healthy Chicken Tortilla Soup, Ro-Tel delivers consistent taste and a pleasant heat without adding unnecessary carbohydrates. It’s truly an indispensable ingredient for achieving that authentic King Ranch profile in your keto casserole.
Meal Prep and Storage Tips
This Keto King Ranch Chicken Casserole isn’t just delicious for dinner; it’s also an excellent candidate for meal prep! Preparing a batch at the beginning of the week can save you precious time on busy days, ensuring you always have a satisfying, low-carb meal ready to go. Simply store any leftovers in an airtight container in the refrigerator for up to 3 days.
Keep in mind that as the casserole sits, the low-carb tortillas will continue to absorb moisture from the creamy sauce, becoming softer. While still perfectly edible and delicious, the texture will evolve. For the freshest taste and best structural integrity of the tortillas, I recommend enjoying it within the first day or two. If you plan to freeze portions, it’s best to do so before baking or immediately after baking and cooling completely. Thaw overnight in the refrigerator and reheat in the oven until warmed through. This makes for a convenient and healthy option for lunches or quick dinners throughout the week.
Step-by-Step Guide to Keto King Ranch Chicken Casserole
Creating this flavorful casserole is straightforward and enjoyable. Follow these detailed steps to achieve a perfectly balanced and delicious keto meal.
Prep Time: 20 minutes
Cook Time: 40 minutes
Total Time: 1 hour
Servings: 6
Net Carbs: Approximately 6 net carbs per serving
Calories: Approximately 335 kcal per serving
Ingredients:
- 3 Low-Carb Tortillas, cut in half
- 1 pound Shredded Chicken
- 1/2 medium Onion, chopped
- 1 Red Bell Pepper, chopped
- 1 cup Heavy Whipping Cream
- 1/2 cup Chicken Broth
- 1 tsp Chicken Bouillon Powder (or 1 cube)
- 1 can RoTel Tomatoes, drained
- Salt and Pepper, to taste
- 1/4 cup Chopped Green Onions (plus additional for garnish)
- 1 1/2 cups Shredded Colby Jack Cheese
- 2 tbsp Butter
Instructions:
- Preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius). This ensures the oven is at the correct temperature for even baking once the casserole is assembled.
- Prepare a 9×13 inch baking dish by greasing it well. Then, arrange the cut low-carb tortilla pieces in a single layer at the bottom of the dish. These will form the base of your casserole.
- In a large skillet, melt the butter over medium heat. This will be the starting point for your flavorful sauce base.
- Add the chopped red bell peppers and onions to the skillet with the melted butter. Sauté them, stirring occasionally, until they become tender and slightly translucent, about 5-7 minutes. This step softens the vegetables and brings out their natural sweetness.
- Pour the heavy whipping cream and chicken broth into the skillet with the sautéed vegetables. Bring the mixture to a gentle simmer and cook, stirring frequently, until the sauce begins to thicken slightly. This forms the rich and creamy base for your casserole.
- Stir in the chicken bouillon powder, the drained Ro-Tel tomatoes, and season generously with salt and pepper to taste. Mix everything well to combine all the flavors thoroughly.
- Fold in the shredded chicken and the chopped green onions into the creamy sauce mixture. Ensure the chicken is evenly coated.
- Spread this savory chicken and sauce mixture evenly over the layer of tortillas in the baking dish. Then, generously sprinkle the shredded Colby Jack cheese over the top, covering the entire casserole.
- Bake in the preheated oven for 25-30 minutes, or until the casserole is bubbly around the edges and the cheese on top is melted and golden brown.
- Once baked, remove the casserole from the oven and let it rest for about 10 minutes before serving. This crucial resting period allows the casserole to set, making it easier to cut and serve without falling apart, and ensuring all the flavors meld beautifully. Garnish with extra green onions if desired.

Serving Suggestions for Your Keto King Ranch Casserole
To complete your low-carb meal, pair this delicious casserole with some complementary sides. The rich, savory flavors of the casserole are wonderfully balanced by fresh and zesty accompaniments.
- Consider serving some crunchy Keto Chili Lime Tortilla Chips on the side. Their zesty, spicy crunch offers a fantastic textural contrast to the creamy casserole.
- For a vegetable-packed option, my family adores Keto Mexican Street Cauliflower. It’s a vibrant dish that perfectly echoes the Southwestern flavors of the casserole.
- Cauliflower rice is always a dependable and versatile low-carb side. A batch of Keto Mexican Cauliflower Rice, with its peppers and hint of lime, would be an exceptionally delicious pairing, adding extra freshness and spice.
- A simple green salad with a light vinaigrette also works well to cut through the richness of the casserole.
Frequently Asked Questions About Keto King Ranch Chicken Casserole
Can I make this casserole ahead of time?
Yes, you can assemble the casserole completely, cover it, and refrigerate it for up to 24 hours before baking. You might need to add an extra 5-10 minutes to the baking time if baking from cold.
Can I freeze King Ranch Chicken Casserole?
Yes, you can freeze it! Assemble the casserole (without baking), wrap it tightly in plastic wrap and then foil, and freeze for up to 2-3 months. Thaw overnight in the refrigerator before baking as directed. Alternatively, you can bake and then freeze individual portions for easy reheating.
What kind of low-carb tortillas should I use?
Look for brands specifically labeled “low-carb,” “keto,” or “net carb” tortillas in your local grocery store. Brands like Mission Carb Balance or La Tortilla Factory are popular choices. Ensure they are soft and pliable enough to layer easily.
Can I use different types of cheese?
Absolutely! While Colby Jack is recommended for its melty texture and mild flavor, feel free to use shredded cheddar, Monterey Jack, or a Mexican cheese blend. For a bit more spice, pepper jack would also be delicious.
What if I don’t have chicken bouillon powder?
You can substitute a chicken bouillon cube, crushed, or use a bit more chicken broth and adjust seasonings to taste. You could also use a keto-friendly chicken base.
Is this recipe spicy?
The spice level primarily comes from the Ro-Tel tomatoes. If you prefer less heat, choose a mild variety of Ro-Tel. For more heat, you can add a pinch of cayenne pepper, a dash of hot sauce, or include some diced jalapeños with the onions and bell peppers.
