Ingredients
Gathering your ingredients is the first step to yummy success! Here’s what you’ll need:
- 1 pound boneless, skinless chicken breast: Cut into bite-size pieces. You want them roughly the same size so they cook evenly! Thighs work great too if that’s what you have.
- 1 medium onion: Chopped into nice, large pieces. The onion gets sweet and tender as it bakes. Yum!
- 1 zucchini: Sliced vertically into four large pieces, then chopped into smaller, bite-size pieces. Zucchini is perfect here – it cooks quickly and soaks up all those flavors.
- 2 tbsp extra virgin olive oil: Our binding agent and flavor carrier! Any olive oil will work.
- 1 tsp garlic powder: Gives us that essential garlic flavor without mincing fresh cloves (score!).
- 1 tsp smoked paprika: This adds a lovely, subtle smoky depth that really elevates the dish.
- 1 tsp dried oregano: A classic herb that pairs perfectly with chicken and veggies.
- 1 tsp cumin: Adds a warm, earthy note that makes this dish extra cozy.
- 1 tsp sea salt or salt to taste: Salt is key to bringing out all the flavors. Start with a teaspoon, you can always add more later.
- ¼ tsp freshly milled pepper or pepper to taste: Freshly ground pepper makes a difference, but pre-ground is totally fine too!
How to Make It
Ready? Let’s get this dinner going. It’s seriously so simple!
- First things first, preheat your oven to a nice hot 425°F (220°C). While it heats up, you can get your chopping done.
- Grab a large bowl. This is where the magic happens! Add in all your wonderful spices: the garlic powder, smoked paprika, dried oregano, cumin, salt, and pepper. Give them a little stir.
- Pour the extra virgin olive oil into the bowl with the spices. Whisk it all together with a fork or spoon until you have a lovely, fragrant marinade paste. It should be thick enough to coat everything nicely.
- Now, add your prepped chicken pieces, chopped onion, and chopped zucchini right into that bowl with the marinade.
- Get your hands in there (or use a spatula or tongs!) and toss everything really well. Make sure every single piece of chicken and veggie is coated in that amazing seasoning mix. This is where all the flavor gets locked in!
- Once everything is coated, transfer the chicken and vegetables from the bowl into a single layer in a baking dish. A 9×13 inch dish works perfectly. Try not to overcrowd it so the veggies can roast instead of steam.
- Pop the dish into your preheated oven. Bake uncovered for about 30 minutes. You’ll know it’s ready when the chicken is cooked through (no longer pink inside) and the vegetables are tender and maybe a little bit caramelized around the edges. Delicious!
- Carefully remove from the oven and serve hot. That’s it! Dinner is served!

Substitutions & Additions
This recipe is super flexible! Feel free to play around based on what you have or what you love.
- Veggies: Broccoli florets, bell peppers (any color!), cherry tomatoes, chopped mushrooms, or even sweet potato cubes (they might need a few extra minutes) would be great additions or swaps for the zucchini or onion.
- Protein: Not a chicken fan? Try this with sausage, shrimp (add them in the last 10 minutes as they cook faster), or even firm tofu cubes for a vegetarian option.
- Spice it up: Add a pinch of red pepper flakes to the seasoning mix for a little kick.
- Add Freshness: A squeeze of fresh lemon juice over everything right before serving is wonderful! Fresh chopped parsley or cilantro as a garnish adds brightness.
- Different Flavors: Swap out the spices for a different vibe! Try Italian seasoning, Cajun seasoning, or even just salt, pepper, and onion powder.
Tips for Success
Want to make sure your dish turns out perfectly every time? Here are a few things I’ve learned:
- Don’t Overcrowd the Pan: This is a big one! If your baking dish is too full, the vegetables will steam instead of roast and get that lovely slightly crispy edge. Use two dishes if you need to.
- Cut Pieces Evenly: Try to make your chicken, onion, and zucchini pieces roughly the same size so they cook at the same rate.
- Adjust Baking Time: Ovens can vary! Check the chicken around 25 minutes. It’s done when it reaches an internal temperature of 165°F (74°C). If your chicken pieces are larger, they might take a bit longer. If they’re smaller, they might be done sooner.
- Prep Ahead: You can chop all your veggies and chicken a day in advance and store them separately in airtight containers in the fridge. Toss them with the marinade just before baking.
How to Store It
Leftovers of this dish are fantastic for lunch the next day!
Let the chicken and vegetables cool completely before transferring them to an airtight container. Store in the refrigerator for up to 3-4 days. To reheat, you can microwave it or warm it gently in a skillet on the stovetop until heated through.
FAQs
Here are a couple of common questions you might have:
Can I use different vegetables?
Absolutely! This recipe is very forgiving. Feel free to swap the zucchini for bell peppers, broccoli, cherry tomatoes, or whatever you have on hand. Just make sure the cooking times are similar, or cut harder vegetables smaller.
What should I serve with this?
This dish is a complete meal on its own, but it’s also great served over rice, quinoa, pasta, or with a side of crusty bread to soak up the juices!
Is this recipe spicy?
No, as written, it’s not spicy. The smoked paprika adds flavor, not heat. If you want it spicy, add a pinch or more of red pepper flakes to the seasoning mix.
Can I use frozen chicken or vegetables?
I recommend using fresh for the best texture and flavor. If using frozen chicken, make sure it’s fully thawed before cutting and marinating. Frozen vegetables tend to release a lot of water when baked, which can make the dish watery, so fresh is definitely preferred here.
