This satisfying Tex-Mex casserole brings together layers of tender shredded chicken, black beans, sweet corn, and aromatic spices, all nestled between soft tortillas and smothered in rich enchilada sauce. The crowning glory is a generous blanket of shredded Mexican cheese that becomes irresistibly bubbly and golden in the oven.
Perfect for family dinners or meal prep, this bake comes together in just 20 minutes of active prep time. The filling can be assembled ahead of time and baked when needed, making it an ideal choice for busy weeknights or casual gatherings.
The smell of bubbling cheese and enchilada sauce still takes me back to rainy Tuesday nights in my tiny first apartment, when a neighbor knocked on my door with a casserole dish because she'd made too much food. I had never thought about layering tortillas like lasagna before, and that first forkful changed everything about how I approached Tex-Mex cooking at home.
Last winter, my sister came over after a rough week at work, and I threw this together while she sat at my counter complaining about her boss. When it came out of the oven, bubbling and golden, she actually went quiet for the first time all evening. There's something about a warm, cheesy casserole that fixes more than just hunger.
Ingredients
- 3 cups cooked, shredded chicken: Rotisserie chicken saves so much time, but poaching your own breasts gives you more control over the seasoning
- 2 cups red enchilada sauce: I've tried making it from scratch, but a good store-bought sauce works beautifully here
- 1 cup canned black beans: Rinse them well to remove the canned taste and excess sodium
- 1 cup corn kernels: Fresh corn is sweetest, but frozen works perfectly when corn's out of season
- 1 small red onion, finely diced: The sweetness of red onion balances the spices better than white onion
- 1 tsp ground cumin: Toast the cumin in a dry pan for 30 seconds before adding it to really wake up the flavor
- 1 tsp chili powder: This provides mild warmth, not heat, so don't be shy with it
- 1/2 tsp garlic powder: Powdered garlic distributes more evenly than fresh cloves in this filling
- Salt and pepper, to taste: Taste your filling before assembling, as rotisserie chicken can already be salty
- 8 small flour or corn tortillas: Corn tortillas give you that authentic texture, but flour rolls more easily
- 2 cups shredded Mexican cheese blend: Shredding your own cheese melts better than pre-shredded bags with anti-caking agents
- Optional toppings: Cilantro, green onions, avocado, sour cream, and lime wedges make each person's portion their own
Instructions
- Prep your oven and dish:
- Preheat to 375°F and grease your baking dish with a little oil or cooking spray
- Mix the filling:
- Combine chicken, sauce, beans, corn, onion, and spices in a large bowl until everything's well coated
- Start the layers:
- Spread sauce on the bottom, add four torn tortillas, then half the filling and some cheese
- Build it up:
- Add another tortilla layer, remaining filling, more cheese, then final tortillas with remaining sauce and cheese on top
- Bake until bubbly:
- Cover with foil for 20 minutes, then uncover for 10 minutes until the cheese turns golden and starts to crisp in spots
- Rest and serve:
- Let it sit for 5 minutes before adding toppings, so portions hold together when you scoop them out
This became my go-to dish for new parents and sick neighbors because it travels well and freezes beautifully. I've dropped it off in the same casserole dish I received that first rainy Tuesday, passing along the comfort someone once gave me.
Making It Ahead
You can assemble the entire casserole up to 24 hours before baking, just wrap it tightly and keep it refrigerated. Add 5-10 minutes to the baking time if it goes into the oven cold from the fridge.
Freezing Instructions
Wrap the unbaked casserole in two layers of foil and freeze for up to 3 months. Thaw overnight in the refrigerator before baking as directed, or bake from frozen at 350°F for about 75 minutes covered, then uncovered.
Serving Suggestions
A crisp green salad with citrus vinaigrette cuts through the richness of the cheese. Some people I know serve it with Spanish rice, but I prefer keeping it simple.
- Warm some extra tortillas on the side for scooping up any escaping filling
- Set up a toppings bar so everyone can customize their portion
- Have hot sauce available for anyone who wants more heat than the chili powder provides
Garnish just before serving so the cilantro stays bright and the avocado doesn't brown. This is the kind of meal that makes people ask when you're making it again.
