There are certain dinners that make you feel like you’ve actually got your life together — and this Mexican chicken and rice bake is absolutely one of them. Bone-in chicken thighs, marinated in a punchy Mexican spice blend and creamy Greek yoghurt, nestled over fragrant herbed rice with courgette and cherry tomatoes, all baked together in one dish until everything is perfectly cooked and golden. Then, just before serving, you pile on a cool, bright kidney bean and avocado salsa that brings the whole thing to life.
It’s the kind of recipe that sounds impressive but is genuinely effortless to pull together on a weeknight. The oven does most of the heavy lifting, and there’s one pan to wash. I’ve made this on a Tuesday in under an hour, and I’ve served it to guests on a Friday — it works for both.

Why This Recipe Works So Well
Let me tell you what makes this particular bake stand out, because there are a few intentional choices here that really pay off.
Bone-in thighs are everything. I know it’s tempting to grab boneless chicken, but for this recipe, you want the bone in. The fat content is higher, the meat stays juicier during the longer oven time, and that extra time is exactly what the rice needs to cook through properly. It’s not a coincidence — they’re perfectly matched.
The yoghurt marinade keeps the chicken incredibly moist. Coating the thighs in Greek yoghurt along with the spice seasoning and a squeeze of lime isn’t just for flavour — the yoghurt acts as a tenderiser and a barrier that prevents the outside from drying out while the inside finishes cooking. The result is chicken that’s beautifully bronzed on the outside and tender all the way through.
The rice cooks right in the vegetable stock. You’re not pre-cooking the rice separately — it goes into the dish raw and absorbs all of the seasoned stock as it bakes. The courgette and cherry tomatoes release their moisture into the rice too, which means every grain is cooked in flavour rather than plain water. It’s the detail that makes a simple dish taste like it came from a restaurant.
The avocado salsa finishes it all off. A warm, hearty bake needs something fresh and zingy on top to cut through the richness. The kidney bean and avocado salsa does exactly that — creamy avocado, citrusy lime juice, a little red onion bite, and a generous amount of coriander. It takes about five minutes to make and genuinely transforms the whole dish.
What You’ll Need
Here’s a quick look at the key ingredients before we dive into the full recipe:
For the rice base: White rice, a small brown onion, garlic, vegetable stock, courgette (zucchini), and cherry tomatoes. The stock is what flavours the rice as it absorbs, so use a good-quality one. The courgette adds bulk and a subtle sweetness, and the halved cherry tomatoes get jammy and almost sauce-like as they roast.
For the chicken: Six bone-in chicken thighs are the star. The marinade is simple — a full packet of Mexican seasoning (35g), Greek yoghurt, and lime or lemon juice. Don’t be tempted to go light on the seasoning. You want the chicken to be well-coated.
For the salsa: Half a tin of drained kidney beans, one large ripe avocado, finely diced red onion, a generous pour of lime juice, and plenty of fresh coriander. The key here is seasoning it well — it should taste bright, punchy, and a little acidic. That’s what makes it pop against the warm rice.
A Few Tips Before You Start
Cover the dish for the first half of the bake. This creates steam, which helps the rice cook evenly and stops the chicken from browning too fast before it’s cooked through. Then you remove the lid and let everything colour up beautifully for the final 25–30 minutes.
Check your rice at the 45-minute mark. All ovens are slightly different. The rice should be tender and have absorbed most of the stock by the time the chicken is fully cooked. If you lift the lid and see the rice is still quite firm and there’s liquid remaining, give it a few extra minutes covered before finishing uncovered.
Season the salsa generously. It’s going over a well-seasoned chicken and rice bake, so it needs enough salt, pepper, and lime juice to hold its own. Taste as you go — a flat salsa will taste like an afterthought; a well-seasoned one will taste like the main event.
Use a proper 30cm baking dish. You need the space for the rice to sit in an even layer with the chicken thighs balanced on top. Too small a dish and the rice won’t cook evenly; too large and it can dry out.
Ingredient Swaps and Variations
No Mexican seasoning packet? You can make your own with a combination of cumin, smoked paprika, garlic powder, oregano, chilli powder, and a pinch of cayenne. It takes two minutes and you likely already have everything in your spice drawer.
Swap kidney beans for black beans. Both work brilliantly in the salsa. Black beans have a slightly earthier flavour; kidney beans are a little more robust. Use whatever you have in the pantry.
Add more vegetables to the rice base. Diced red capsicum/bell pepper is a great addition. So is frozen corn — just stir it in at the start. This is a very forgiving base.
Make it spicier. If you love heat, add a finely diced fresh chilli to the salsa, or use a spicier seasoning blend on the chicken. A drizzle of hot sauce at the end doesn’t hurt either.
Courgette substitution. No courgette? Diced zucchini (same thing, different name), butternut squash cubed small, or even diced eggplant would all work well here.
Can I Make This Ahead of Time?
Yes, and it actually holds up really well. You can marinate the chicken the night before — in fact, it gets even more flavourful with a longer marinating time. Just coat the thighs, cover the bowl, and pop it in the fridge overnight.
The rice base can also be prepped ahead: combine the rice, onion, garlic, and vegetables in the baking dish, cover, and refrigerate. When you’re ready to cook, pour in the stock, place the marinated chicken on top, and bake as directed.
The salsa is best made fresh — avocado oxidises quickly and the texture suffers after a few hours, so I’d always prepare this one just before serving.
Leftovers and Reheating
This bake reheats beautifully and makes a brilliant next-day lunch. Store any leftovers in an airtight container in the fridge for up to three days. When reheating, add a small splash of water or stock to the rice to loosen it back up before warming through in the microwave or a low oven covered in foil.
The salsa is best eaten the day it’s made — by day two, the avocado loses its colour and the texture softens too much. If you have leftover rice and chicken without salsa, you can easily make a fresh batch of salsa to serve with it.
Bonus idea: Leftover chicken and rice makes an incredible burrito filling. Shred the chicken, spoon some of the rice alongside it, and wrap the whole thing in a warm flatbread with a dollop of yoghurt and fresh coriander. Weeknight lunch sorted.
This also pairs well with a simple Pineapple Chicken Rice Bowl style of thinking if you want to spin the leftovers into something new — the citrus and fresh elements play off each other really nicely.
What to Serve Alongside
Honestly? This is a complete meal as it is. The rice, chicken, vegetables, beans, and avocado cover all of your nutritional bases, and with four generous portions it’s very satisfying. But if you want to round it out:
A simple green salad dressed with lime juice and olive oil is a lovely, fresh counterpoint. Warm flatbreads on the side are brilliant for scooping up the saucy, herbed rice. And if you want to go all out, a bowl of cooling yoghurt stirred through with a little garlic and coriander alongside the salsa makes for a gorgeous spread.
Step-by-Step: How to Make Mexican Chicken and Rice Bake
1. Preheat your oven to 200°C (fan bake).
2. Prepare the rice base. In a 30cm baking dish, combine 1.5 cups of white rice, the diced brown onion, sliced garlic cloves, and 3 cups of vegetable stock. Fold in the diced courgette and the halved cherry tomatoes. Give everything a gentle stir so the rice is evenly distributed and the vegetables are spread throughout.
3. Marinate the chicken. In a bowl, combine the 6 bone-in chicken thighs with the full packet of Mexican seasoning, ¼ cup of Greek yoghurt, and 1 tablespoon of lime or lemon juice. Season generously with salt and pepper. Mix well so every thigh is coated all over.
4. Arrange and cover. Nestle the marinated chicken thighs on top of the rice mixture. Cover the baking dish tightly with a lid or foil and bake for 30 minutes.
5. Uncover and finish baking. Remove the lid and return the dish to the oven for a further 25–30 minutes, until the chicken is cooked through (golden on top and reading 75°C / 165°F in the thickest part), and the rice is tender and has absorbed the stock.
6. Make the salsa. While the chicken finishes baking, combine the drained kidney beans, diced avocado, finely diced red onion, ¼ cup of lime juice, and 1 cup of fresh coriander in a bowl. Season well with salt and pepper and stir gently to combine.
7. Serve. Once the chicken and rice are done, spoon the fresh bean and avocado salsa generously over the top and bring straight to the table. Serve family-style straight from the baking dish. Feeds 4.
A Quick Note on the Mexican Seasoning
The recipe calls for a 35g packet of Mexican seasoning — the kind you’d find in the spice aisle. These blends typically contain a combination of cumin, coriander, chilli, paprika, garlic, and oregano, giving you all the warm, earthy, slightly smoky notes that make this dish sing. It’s an easy shortcut that delivers a lot of flavour without having to measure out six individual spices. If your local supermarket carries it, grab two packets and keep a spare for next time — you’ll be making this again.

Instructions
Chicken and Rice Bake
- Preheat the oven to 200°C (fan bake / 390°F).
- In a 30cm baking dish, combine the white rice, diced onion, sliced garlic, and vegetable stock. Fold in the diced courgette and halved cherry tomatoes, spreading everything into an even layer.
- In a large bowl, combine the chicken thighs with the Mexican seasoning, Greek yoghurt, and lime juice. Season well with salt and pepper and mix until every thigh is thoroughly coated.
- Place the marinated chicken thighs on top of the rice mixture. Cover the baking dish tightly with a lid or foil and bake for 30 minutes.
- Remove the lid and return the dish to the oven for a further 25–30 minutes, until the chicken is golden on top and fully cooked through (internal temperature of 75°C / 165°F), and the rice is tender and has absorbed the stock.
Bean and Avocado Salsa
- While the chicken finishes baking, combine the drained kidney beans, diced avocado, finely diced red onion, lime juice, and chopped coriander in a bowl. Season generously with salt and pepper and stir gently to combine.
- Once the chicken and rice are cooked, spoon the bean and avocado salsa generously over the top and serve immediately straight from the baking dish.
Notes
- Use bone-in chicken thighs for the best results — the extra fat and cooking time allows the rice to cook perfectly without the chicken drying out.
- The yoghurt coating keeps the chicken moist and helps it brown beautifully. Don’t skip it.
- Check the rice at the 45-minute mark — it should be tender and have absorbed most of the stock. If it still feels firm, cover and give it a few extra minutes before finishing uncovered.
- Make the salsa fresh just before serving. Avocado discolours quickly and the texture suffers if made too far in advance.
- Leftovers keep in an airtight container in the fridge for up to 3 days. Add a splash of water or stock when reheating to loosen the rice.
- No Mexican seasoning packet? Substitute with a mix of 1 tsp cumin, 1 tsp smoked paprika, ½ tsp garlic powder, ½ tsp dried oregano, ½ tsp chilli powder, and a pinch of cayenne.
- Black beans can be used in place of kidney beans in the salsa.
