Ingredients

Use these measured ingredients as listed. Do not substitute the amounts if you want the same yield and cooking balance.

3 Tbsp avocado oil, divided
1 medium yellow onion, finely chopped
5 cloves garlic, minced
3 large sweet potatoes, chopped (800 g total)
3 large carrots, chopped
3 bunches broccoli or 2 crowns broccoli
4 medium-sized zucchini
4 Tbsp spices and herbs of choice — I use ground cumin, dried basil and parsley
1 tsp sea salt, to taste
1/4 tsp black pepper, to taste
4 to 5 lbs boneless skinless chicken breasts, chopped

Equipment

1 large rimmed baking sheet or roasting pan
Mixing bowls
Sharp knife and cutting board
Measuring spoons
Spoon or spatula for tossing
Aluminum foil or parchment (optional, for easier cleanup)

Prep ahead

You can chop vegetables and chicken up to a day in advance and store them separately in airtight containers in the fridge. Mince the garlic and finely chop the onion the evening before to save time. If you plan to cook multiple batches, label containers with the date so you use the oldest produce first.

Taste and texture tips

Cut the sweet potatoes and carrots into similar-sized pieces so they roast evenly. If you prefer softer sweet potatoes, cut them smaller; for a firmer bite, keep them larger.
Broccoli florets cook faster than root vegetables; add them later in the roasting time if you want them crisp-tender.
Zucchini releases moisture as it cooks. Toss it with a bit of oil and space it out on the sheet pan to avoid stewing.
Adjust the 4 Tbsp spices and herbs to your taste. The suggested blend of ground cumin, dried basil, and parsley gives warmth, herby notes, and brightness.

Step-by-step instructions

The directions below have been rewritten into a clear, logical sequence while preserving ingredient amounts and the original order of operations.

Preheat the oven to 425°F (220°C). Line a large rimmed baking sheet with parchment or foil if desired for easier cleanup.
Prepare all produce and chicken: finely chop 1 medium yellow onion; mince 5 cloves garlic; chop 3 large sweet potatoes so that the total weight is about 800 g; chop 3 large carrots; cut 3 bunches broccoli (or 2 crowns) into florets; and slice 4 medium-sized zucchini into half-moons or thick rounds. Chop 4 to 5 lbs boneless skinless chicken breasts into bite-sized pieces.
Divide the 3 Tbsp avocado oil into two portions: reserve 1 Tbsp for the chicken and use the remaining 2 Tbsp for the vegetables.
In a large bowl, combine the chopped sweet potatoes and carrots with 2 Tbsp avocado oil, 1 tsp sea salt, 1/4 tsp black pepper, and 4 Tbsp of your chosen spices and herbs (I use ground cumin, dried basil, and parsley). Toss everything until the vegetables are evenly coated.
Spread the seasoned sweet potatoes and carrots on one half of the prepared baking sheet in a single layer, leaving space on the other half for the chicken and quicker-cooking vegetables. Place the sheet in the preheated oven and roast for 15 minutes to give the root vegetables a head start.
While the root vegetables roast, heat the reserved 1 Tbsp avocado oil in a skillet over medium heat. Add the finely chopped onion and sauté for 3 to 4 minutes until softened and translucent. Add the minced garlic and cook for another 30 to 60 seconds until fragrant. Remove the skillet from the heat and allow the onion-garlic mixture to cool slightly.
In a large bowl, combine the chopped chicken pieces with the sautéed onion and garlic, making sure the onion and garlic are distributed evenly among the chicken. Add a pinch of salt or a bit of the remaining spice blend if you want extra seasoning on the chicken.
After the initial 15 minutes of roasting for the sweet potatoes and carrots, remove the baking sheet from the oven. On the empty half of the sheet, arrange the seasoned chicken in a single layer. Add the broccoli florets and the sliced zucchini around the chicken, giving each piece some space. If the baking sheet is too crowded, use a second sheet to ensure even roasting; crowded pans steam food instead of roasting it.
Return the baking sheet to the oven and roast for an additional 15 to 20 minutes, or until the chicken is cooked through (internal temperature reaches 165°F / 74°C) and the vegetables are tender and slightly caramelized at the edges. If you prefer crispier vegetables, switch the oven to broil for 2 to 3 minutes at the end, watching closely to prevent burning.
Once cooked, remove the pan from the oven. Allow the chicken and vegetables to rest on the sheet for 5 minutes — this helps the juices redistribute in the chicken and keeps everything moist.
Taste a piece of the chicken and a vegetable; adjust seasoning with a little more sea salt or black pepper if needed. If you like, sprinkle additional dried parsley or a squeeze of lemon juice over the finished pan for brightness.
Portion the Meal Prep Chicken and Vegetables (Paleo, Whole30) into meal containers while slightly warm. Store in airtight containers in the refrigerator for up to 4 days. Reheat in the microwave or rewarm in a skillet on the stovetop with a splash of water or oil to prevent drying out.

Serving suggestions

This Meal Prep Chicken and Vegetables (Paleo, Whole30) is satisfying on its own, but you can elevate it with small finishing touches:

Fresh herbs: A sprinkle of chopped parsley or basil adds freshness.
Acid: A squeeze of lemon or a splash of apple cider vinegar brightens the flavors.
Crunch: Toasted pumpkin seeds or sliced almonds add texture if allowed in your plan.
Heat: A pinch of red pepper flakes or a drizzle of hot sauce for those who like spice.

Make it your own

Small swaps keep this recipe in heavy rotation without getting boring. Use different herbs or spice blends: smoked paprika and oregano, za’atar, or a taco-style seasoning all work. Swap broccoli for cauliflower or Brussels sprouts if you prefer. If you want more vegetables per batch, add an extra zucchini or another crown of broccoli and roast on a second sheet to avoid crowding. The key is consistent knife cuts for even cooking and respecting the original ingredient amounts so the timing and balance remain reliable.

Storing and reheating

Refrigerator: Store in airtight containers for up to 4 days. Keep chicken and vegetables together or in separate containers if you prefer more control when reheating.
Freezer: For longer storage, freeze in airtight containers for up to 3 months. Thaw overnight in the refrigerator before reheating.
Reheating: Microwave on medium power in 30–60 second increments until warmed through. For better texture, reheat in a skillet over medium heat with a teaspoon of oil, stirring occasionally until heated.

Nutrition notes

This Meal Prep Chicken and Vegetables (Paleo, Whole30) balances lean protein with nutrient-dense vegetables and healthy fat from avocado oil. Sweet potatoes offer filling complex carbohydrates and beta-carotene, while broccoli and zucchini contribute fiber and vitamins. Seasoning with herbs and spices keeps sodium moderate while delivering big flavor.

Common questions

How do I know the chicken is done? The safest method is to check the internal temperature with an instant-read thermometer; it should read 165°F (74°C). If you don’t have a thermometer, cut a piece open: the juices should run clear and the meat should be opaque throughout.

Can I use bone-in chicken? You can, but bone-in pieces require a longer roast time. If you choose bone-in, adjust the roasting time upward and ensure the chicken reaches the safe internal temperature for poultry.

What if my pan is crowded? Crowded pans steam instead of roast. If you need more space, use a second baking sheet and roast both at the same time. This preserves caramelization and texture.

Final notes

This Meal Prep Chicken and Vegetables (Paleo, Whole30) recipe proves that clean-eating meals can be effortless, flavorful, and family-friendly. The straightforward method and flexible spice profile make it easy to personalize while keeping meal prep stress-free. Make a double batch to send to work, feed a family, or freeze portions for later — it’s dependable, nourishing, and delicious.
