Instructions

1. 1

   Heat the oven

   Preheat the oven to 200°C (400°F). Lightly grease a 23 × 33 cm (9 × 13-inch) baking dish.

2. 2

   Season the chicken

   Season the chicken with the taco seasoning, cumin, smoked paprika, chilli powder if using, salt and pepper. Drizzle with the olive oil and rub it over the chicken.

3. 3

   Mix the vegetables

   In a bowl, combine the black beans, corn, drained tomatoes with green chillies, half the red onion and half the bell pepper. Add a pinch of salt.

4. 4

   Make the sauce

   Stir the Greek yoghurt and salsa together until combined.

5. 5

   Layer the dish

   Arrange the chicken in the baking dish. Spread the bean-and-corn mixture around and over it, then spoon the yoghurt-salsa sauce evenly on top.

6. 6

   Add the toppings

   Scatter the remaining onion and bell pepper over the dish. Add the sliced jalapeño if you want extra heat.

7. 7

   Bake covered

   Cover the dish with foil and bake for 18–20 minutes.

8. 8

   Finish with cheese

   Remove the foil and sprinkle the cheese over the top. Bake for a further 8–10 minutes, until the chicken reaches 74°C (165°F) and the cheese is melted and bubbling.

9. 9

   Rest and serve

   Leave the bake to rest for 5 minutes. Finish with coriander and a squeeze of lime, then serve over rice or cauliflower rice, or with warm tortillas.

What is Mexican chicken bake?

This is a home-style, Mexican-inspired casserole rather than a single traditional regional dish. It brings together taco-seasoned chicken, beans, corn, tomatoes and cheese in one baking dish.

The yoghurt and salsa make a quick creamy topping, while the beans and vegetables turn the chicken into a generous meal. The layered method also keeps preparation straightforward on a weeknight.

Nutrition and macros by portion

The nutrition label shows one serving as written: 400 calories, 44g protein, 28g carbs, 12g fat.

Chicken and black beans provide most of the protein, while the beans, corn and any rice or tortillas contribute much of the carbohydrate. Cheese, olive oil and Greek yoghurt supply much of the fat, with amounts varying by the products used. For a balanced plate, pair a serving with a generous portion of vegetables or a salad.

Choose the chicken

Even thickness: Thin-sliced or evenly pounded breasts cook more consistently than thick, uneven pieces. If using larger breasts, check their thickest parts carefully for doneness.

Seasoning: Taco seasoning provides the main flavour, with cumin, smoked paprika and optional chilli powder adding extra warmth. Since seasoning blends vary in saltiness, use the additional salt with a light hand.

Build the bean mixture

Drain well: Rinsing the beans and draining the tomatoes helps prevent excess liquid from collecting in the dish. Drain canned corn too, if that is what you are using.

Split the vegetables: Mixing half the onion and pepper into the beans distributes them through the bake; reserving the rest for the top adds colour and texture.

Keep the topping creamy

Yoghurt and salsa: Stir them together before adding them so the sauce is easy to spoon over the chicken. Plain Greek yoghurt gives the topping body, while the salsa brings its own seasoning and heat.

Gentle handling: Spread the sauce across the top rather than mixing it thoroughly into the beans. This keeps the layers distinct as they bake.

Check the bake for doneness

Covered stage: Foil helps the chicken and vegetables cook through during the first 18–20 minutes. The final uncovered bake melts and browns the cheese.

Temperature cue: Check the thickest piece of chicken with a thermometer; it should reach 74°C (165°F). If it has not, continue baking and check again rather than relying only on the clock.

Serve it your way

Rice or tortillas: Serve with rice or warm tortillas to make the meal more substantial and to catch the sauce. Cauliflower rice is another option if you prefer a lighter accompaniment.

Fresh finish: Coriander and lime are added after baking, so their fresh, bright flavour contrasts with the warm, savoury topping.

Recipe notes & tips

• Use chicken pieces of similar thickness so they finish cooking at about the same time.
• Drain the beans and tomatoes thoroughly to avoid a watery bake.
• Taste your salsa before adding extra salt, as its seasoning can vary.
• For a mild dish, leave out the jalapeño and choose mild salsa.
• Check the chicken temperature at its thickest point before serving.
• Let the dish rest for 5 minutes so it is easier to portion.

Variations

• Add extra heat: Use hot salsa or include the sliced jalapeño.
• Change the beans: Use drained pinto beans in place of black beans.
• Swap the cheese: Use grated Monterey Jack or Cheddar instead of a Mexican blend.
• Add more vegetables: Include sliced courgette alongside the pepper.
• Make it smoky: Add a little extra smoked paprika to the chicken seasoning.

Common mistakes to avoid

• Uneven chicken pieces: Pound or slice them to a similar thickness so they cook more evenly.
• Watery vegetables: Drain the canned ingredients well before mixing them.
• Too much salt: Check the seasoning on the taco mix and salsa before adding salt.
• Skipping the temperature check: Bake until the thickest chicken piece reaches 74°C (165°F).
• Browning too soon: Keep the dish covered for the first 18–20 minutes, then uncover to add cheese and finish baking.

How to store

Refrigerate leftovers in a sealed container for up to 3 days. Reheat until piping hot in the oven or microwave; add a splash of water if the sauce seems dry. Avoid repeatedly reheating the same portion.
