Equipment

• Large skillet
• 9×13-inch baking dish (or similar)
• Mixing bowl
• Spatula and spoon
• Measuring spoons and cups

Prep and cook time

• Prep: 20 minutes
• Bake: 20–25 minutes
• Total: about 45 minutes

Step-by-step directions

1. Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish and set it aside.
2. Heat 2 tbsp olive oil in a large skillet over medium heat.
3. Add 1 small zucchini (diced), 4 green onions (sliced), and 1/2 cup green pepper (diced) to the skillet. Sauté, stirring occasionally, until the vegetables are softened, about 5 minutes.
4. Stir in 1/4 cup green olives (sliced) and 2 cups baby spinach (fresh, chopped). Cook until the spinach wilts, about 1–2 minutes.
5. Season the vegetable mixture with 1 tsp cumin and salt & pepper to taste. Stir to combine and remove the skillet from the heat.
6. In a large mixing bowl, combine the sautéed vegetables, 2 cups rotisserie chicken (cooked, chopped or shredded), and 7.5 oz black beans (1/2 can). Mix gently so the ingredients are evenly distributed.
7. Pour 7 oz salsa (1 small can) into the chicken and vegetable mixture and fold it in. Taste and adjust seasoning if needed.
8. Place a thin layer of the filling in the bottom of the prepared baking dish. Tear or slice 9 corn tortillas into pieces and cover the filling evenly with enough tortilla pieces to form a layer.
9. Pour 2 cups mild green enchilada sauce over the tortilla layer, using just enough to moisten the tortillas and create a saucy base.
10. Sprinkle about one-third of 1/2 lb cheddar cheese (grated) over the sauced tortillas.
11. Repeat the layering process: add another layer of the chicken and vegetable filling, another torn tortilla layer, more enchilada sauce, and another third of the cheese. Finish with the remaining filling if needed, a final tortilla layer, the remaining enchilada sauce, and the last of the grated cheese.
12. Once the casserole is assembled, cover it loosely with foil and bake in the preheated oven for 15 minutes. Remove the foil and bake for an additional 5–10 minutes, or until the cheese is melted and bubbly and the edges are slightly golden.
13. Remove the casserole from the oven and let it rest for 5–10 minutes. This helps the layers set and makes slicing easier.
14. Garnish with 1/2 bunch cilantro (fresh, roughly chopped) and any desired toppings: sour cream, diced tomatoes, sliced avocado, shredded lettuce, extra cilantro, and a squeeze of lime juice.
15. Serve warm, scooping generous portions so each plate gets a bit of cheese, sauce, chicken, and vegetables.

Tips for success

• If your rotisserie chicken has skin or bone, use only the meat. Chop or shred to your preferred bite size.
• To prevent soggy tortillas, don’t over-soak each layer with sauce; pour enough to keep them moist but not falling apart.
• Make-ahead: Assemble the casserole up to 24 hours in advance, cover tightly, and refrigerate. Add a few extra minutes to the covered bake time when cooking from cold.
• Leftovers store well in the refrigerator for 3–4 days and reheat nicely in the oven or microwave.

Serving suggestions

This Chicken And Vegetable Enchilada Casserole pairs well with a crisp green salad or a simple bowl of rice. Offer lime wedges and extra cilantro at the table so everyone can brighten their portion. For a creamy contrast, serve with sour cream or plain yogurt and sliced avocado.

Notes on ingredients

• Black beans: If using canned beans, drain and rinse before adding to reduce sodium.
• Cheese: Use freshly grated cheddar for best melting and flavor.
• Tortillas: Corn tortillas work best for texture and flavor, but you can substitute with flour tortillas if preferred.
