Ingredients
For the casserole base
- 10 small corn tortillas, cut into 1-inch squares
- 2 boneless skinless chicken breasts, cooked and chopped
- 2 cups shredded cheddar cheese
For the flavor components
- 1 can black olives (398ml can), drained
- 1 can ROTEL (284ml can)
- 1 can cream of chicken soup (284ml can)
- 1 can green chilies (127ml can)
For garnish
- Fresh chopped cilantro (optional)
Instructions
Preparation
- 1 Preheat your oven to 350°F (175°C). This moderate temperature ensures even cooking without drying out the chicken or burning the cheese. Spray a 9×13 inch baking pan with cooking spray, making sure to coat the corners where ingredients tend to stick.
Assembly
- 2 In a large mixing bowl, combine all ingredients except the cilantro garnish. Use a sturdy mixing bowl as this mixture will be quite thick and chunky. Stir everything together until the cream of chicken soup coats all ingredients evenly and the cheese is well distributed throughout the mixture.
- 3 Spread the mixture evenly in your prepared baking pan. Use a silicone spatula to press the mixture gently into the corners and create an even surface. This ensures uniform cooking and prevents some areas from drying out while others remain undercooked.
Baking
- 4 Bake for 45 minutes, until the casserole is bubbling vigorously around the edges and the top is golden brown. The cheese should be melted and slightly crispy on top, while the center should be hot and bubbly. If the top browns too quickly, tent loosely with aluminum foil for the remaining cooking time.
Finishing
- 5 Remove from oven and let rest for 5 minutes before serving. This brief resting period allows the casserole to set slightly, making it easier to serve neat portions. Garnish with fresh chopped cilantro if desired, and serve hot while the cheese is still beautifully melted.

Nutritional Information and Health Benefits
Key Nutritional Highlights
This hearty casserole provides approximately 320 calories per serving when divided into 6 portions. Each serving delivers substantial protein from the chicken (about 25 grams), while the corn tortillas contribute complex carbohydrates for sustained energy. The cheese adds calcium and additional protein, while the vegetables provide essential vitamins and minerals.
Health Benefits of Main Ingredients
The chicken breast provides high-quality lean protein essential for muscle maintenance and satiety. Corn tortillas offer B vitamins, particularly niacin and folate, while being naturally gluten-free. The tomatoes in Rotel contribute lycopene, a powerful antioxidant that supports heart health and may have anti-inflammatory properties. Black olives provide healthy monounsaturated fats and vitamin E, while green chilies add vitamin C and capsaicin, which may boost metabolism.
Dietary Considerations
This recipe contains dairy and is naturally gluten-free when made with pure corn tortillas. It’s rich in protein and moderate in carbohydrates, making it suitable for those following balanced macro diets. The sodium content is moderate due to canned ingredients, so those watching sodium intake may want to choose low-sodium versions of the canned components.
Smart Swaps and Ingredient Substitutions
Common Substitutions:
- Corn tortillas → Flour tortillas cut into squares (if gluten isn’t a concern)
- Cheddar cheese → Monterey Jack, Mexican cheese blend, or pepper jack for different flavor profiles
- Cream of chicken soup → Cream of mushroom or cream of celery soup
- Black olives → Green olives, diced bell peppers, or corn kernels
Budget-Friendly Swaps:
- Rotisserie chicken → Cook your own chicken breasts or thighs in a slow cooker
- Name-brand Rotel → Generic diced tomatoes with green chilies
- Block cheese you shred yourself → Often more economical than pre-shredded
Pantry Emergency Substitutions:
- Fresh cilantro → Dried cilantro (use 1 tablespoon) or fresh parsley

- Rotel → Regular diced tomatoes plus a small can of green chilies
Pro Tips for Substitutions:
- When using different cheeses, maintain the 2-cup measurement for proper texture
- If substituting vegetables, keep similar moisture content to prevent watery results
- Store leftover canned ingredients in airtight containers in the refrigerator for up to 3 days

Perfect Pairing Suggestions
Beverage Pairings
A crisp Mexican lager or light beer complements the Tex-Mex flavors beautifully without overwhelming the dish. For wine lovers, try a Sauvignon Blanc or unoaked Chardonnay that can stand up to the cheese and spices. Non-alcoholic options include fresh lime agua fresca, iced tea with lime, or sparkling water with a splash of citrus to cleanse the palate between bites.
Side Dish Recommendations
Serve alongside Mexican rice or cilantro-lime rice to soak up any extra sauce. A fresh pico de gallo or corn and black bean salad adds bright, contrasting flavors and textures. Roasted vegetables like bell peppers and onions complement the Southwestern theme, while a simple green salad with lime vinaigrette provides a refreshing counterpoint to the rich, cheesy casserole.
Complete Meal Ideas
Start with tortilla chips and guacamole or a light gazpacho soup. The casserole serves as a perfect main course for casual family dinners or potluck gatherings. Finish with churros and chocolate sauce or a simple flan for an authentic Mexican-inspired meal. For entertaining, set up a taco bar with additional toppings like sour cream, salsa, and jalapeños.
Occasion Suggestions
This recipe shines at casual gatherings, game day parties, and family weeknight dinners. It’s perfect for meal prep Sunday, as it reheats beautifully throughout the week. The recipe easily doubles for larger crowds and works wonderfully for church potlucks or neighborhood gatherings where you need something hearty and crowd-pleasing.
Pro Tips and Troubleshooting
Make-Ahead Strategies
Assemble the entire casserole up to 24 hours in advance, cover tightly with plastic wrap and refrigerate. When ready to bake, remove from refrigerator 30 minutes before cooking to bring closer to room temperature, then bake as directed, adding an extra 5-10 minutes if needed. You can also freeze the assembled casserole for up to 3 months – thaw overnight in refrigerator before baking.
Storage and Reheating
Store leftovers in the refrigerator for up to 4 days in airtight containers. Reheat individual portions in the microwave for 1-2 minutes, stirring halfway through. For larger portions, reheat in a 350°F (175°C) oven covered with foil for 15-20 minutes until heated through. The texture stays remarkably good, though the tortillas may soften slightly.
Common Troubleshooting
If your casserole seems watery, drain the Rotel and black olives thoroughly before mixing. Too dry? Add an extra 1/2 can of cream soup. For crispier edges, use a metal pan instead of glass and bake on the lower oven rack for the last 10 minutes. If the top browns too quickly, tent with foil and continue baking until the center is hot and bubbly.
Scaling Tips
This recipe doubles perfectly for a crowd – use two 9×13 inch pans or one large roasting pan. For smaller households, halve the recipe and bake in an 8×8 inch pan for 35-40 minutes. The cooking time remains nearly the same regardless of pan size since the depth stays consistent.
This South of the Border Chicken casserole proves that sometimes the best recipes are the simplest ones – where a handful of pantry staples transforms into something that brings everyone to the table with smiles on their faces and empty plates when they’re done.
