🥗 Ingredients

The Protein and Aromatics

  • 4 cups Cooked Chicken (shredded, rotisserie chicken works perfectly)
  • 1 Yellow Onion (medium-sized, finely diced)
  • 1 Green Bell Pepper (seeded and diced)
  • 2 tablespoons Unsalted Butter (for sautéing)

The Signature Sauce

  • 10.5 ounces Cream of Mushroom Soup (one standard can)
  • 10.5 ounces Cream of Chicken Soup (one standard can)
  • 10 ounces Ro-Tel Diced Tomatoes and Green Chilies (one can, undrained)
  • 1/2 cup Chicken Broth (low sodium)
  • 1 tablespoon Chili Powder (mild or medium)
  • 1 teaspoon Ground Cumin
  • 1/2 teaspoon Garlic Powder

Layers and Toppings

  • 12-15 pieces Corn Tortillas (cut into 1-inch strips or quarters)
  • 2 cups Sharp Cheddar Cheese (freshly shredded)
  • 1 cup Monterey Jack Cheese (freshly shredded)
  • 1/4 cup Fresh Cilantro (chopped for garnish)
  • 2 tablespoons Pickled Jalapeños (optional, for garnish)

👨‍🍳 Instructions

  1. 1

    Preheat your oven to 350°F (175°C). Lightly grease a 9x13-inch baking dish with butter or non-stick cooking spray.

  2. 2

    In a large skillet over medium heat, melt the 2 tablespoons of butter. Add the diced onion and green bell pepper, sautéing for 5-7 minutes until the vegetables are softened and the onion is translucent.

  3. 3

    In a large mixing bowl, whisk together the cream of mushroom soup, cream of chicken soup, the entire can of Ro-Tel (with juices), chicken broth, chili powder, cumin, and garlic powder until smooth.

  4. 4

    Stir the sautéed onions and peppers into the soup mixture. Fold in the shredded chicken until every piece is well-coated in the savory sauce.

  5. 5

    Begin the layering process by spreading about 1/2 cup of the sauce mixture onto the bottom of the prepared baking dish to prevent sticking.

  6. 6

    Create a layer using half of the corn tortilla strips, overlapping them slightly to cover the bottom of the dish completely.

  7. 7

    Spread half of the chicken and sauce mixture evenly over the tortillas.

  8. 8

    Sprinkle half of the Cheddar and Monterey Jack cheese blend over the chicken layer.

  9. 9

    Repeat the layers: add the remaining tortilla strips, followed by the remaining chicken mixture, and finally the remaining cheese.

  10. 10

    Place the dish in the center rack of the oven and bake for 30-35 minutes. The cheese should be bubbly and starting to turn golden brown around the edges.

  11. 11

    Remove from the oven and let the casserole rest for 10 minutes before serving. This allows the layers to set so you get clean slices.

  12. 12

    Garnish with fresh cilantro and pickled jalapeños if desired, and serve warm.

💡 Chef's Tips

Always shred your own cheese from a block for the best melt; pre-shredded cheese is coated in potato starch which can make the sauce grainy. If you prefer a crunchier texture, you can substitute the corn tortillas with lightly crushed sturdy tortilla chips. Don't drain the Ro-Tel; the liquid contains all the spicy, vinegary flavor that cuts through the richness of the cream soups. This dish is a great make-ahead meal; assemble it the night before, cover with foil, and refrigerate, then add 10 minutes to the baking time. For a smoky twist, use a rotisserie chicken that has been smoked or add a teaspoon of smoked paprika to the sauce.

🍽️ Serving Suggestions

Serve with a side of Mexican street corn (Elote) for a sweet and savory contrast. A crisp green salad with a lime-vinaigrette helps balance the richness of the cheese and cream. Top each serving with a dollop of sour cream and a few slices of fresh avocado. Pair with a cold Mexican lager or a classic lime margarita on the rocks. Warm flour tortillas on the side are great for scooping up any extra sauce.
