Essential Ingredients
Here’s what you’ll need to make this delicious dish:
-
Boneless, Skinless Chicken Breasts: I usually use about 3-4 chicken breasts, but feel free to adjust based on how many people you’re feeding.
-
Fresh Garlic: Choose firm cloves for the best flavor; minced garlic adds that extra zing!
-
Onion: A medium onion enhances the base flavor; sauté until translucent for maximum sweetness.
-
Green Bell Peppers: Chopped bell peppers add crunch and color; feel free to swap for red or yellow if you prefer.
-
Canned Cream of Chicken Soup: This is your secret weapon for creaminess; opt for low-sodium versions if you’re watching salt intake.
-
Diced Tomatoes with Green Chilies: These pack a flavorful punch; they add moisture and a hint of heat.
-
Tortilla Chips: Crunchy chips create layers in the casserole; don’t crush them too finely!
-
Shredded Cheddar Cheese: A generous amount on top creates that gooey finish everyone loves.
-
Spices (Cumin & Chili Powder): These spices give your casserole character; adjust depending on how spicy you like it.
-
Olive Oil: A drizzle helps sauté vegetables perfectly without sticking.

Let’s Make it Together
Preheat oven to 350°F (175°C). Spray a 9×13 baking dish with nonstick cooking spray. This step ensures your glorious creation doesn’t stick!
Heat olive oil in a large skillet over medium heat. Add chopped onions and bell peppers, cooking until soft—about 5 minutes—until they become fragrant and colorful.
Stir in minced garlic and cook until fragrant—this should take about 30 seconds. You’ll know it’s ready when your kitchen smells heavenly!
Add shredded cooked chicken along with cream of chicken soup and diced tomatoes with green chilies. Mix everything well until combined into a creamy delight.
Layer half of your tortilla chips in the bottom of the prepared baking dish. Pour half of the chicken mixture over them before topping with half of the shredded cheese.
Repeat by layering the remaining tortilla chips followed by the rest of the chicken mixture and finish with more cheese on top—because who doesn’t love extra cheese?
Bake uncovered for 30-35 minutes or until bubbly and golden brown on top. The anticipation will have your mouth watering as you await those crispy edges!
Let it cool slightly before serving—a few minutes will help those layers settle nicely.
Now gather your loved ones around the table because it’s time to dig into this comforting King Ranch chicken casserole!
