Ingredients
Serves 4–6
- 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, chopped into florets
- 4 medium-sized zucchini, sliced or chopped
- 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
- Baking sheets (2 large or 3 medium)
- Mixing bowls
- Sharp knife and cutting board
- Large spoon or spatula
- Measuring spoons
- Meal prep containers
Prep tips
- Cut the vegetables into similar-sized pieces so they roast evenly—about 1-inch chunks for sweet potatoes and carrots, florets for broccoli, and half-moons or chunks for zucchini.
- Pat the chicken dry before chopping; this helps it brown when roasted.
- If your oven has hot spots, rotate baking sheets once during roasting to ensure even color and cooking.
- Want extra crispness? Roast vegetables and chicken separately so each can get the ideal temperature and time without steaming one another.
Flavor variations
- Mexican twist: swap the cumin for chili powder and smoked paprika, and add a squeeze of lime before serving.
- Mediterranean: replace the cumin with oregano and rosemary, toss vegetables with lemon zest and a drizzle of extra avocado oil.
- Garlic-herb: use extra dried parsley and basil and add a pinch more black pepper for a brighter profile.
Step-by-step instructions
The following instructions follow the ingredient list and present a clear, ordered approach to roast the vegetables and chicken, then assemble for the week. Quantities and the order reflect the original ingredient amounts.
- Preheat your oven to 400°F (200°C). Line two large baking sheets with parchment paper or lightly oil them with a small amount of avocado oil to prevent sticking.
- Prepare the vegetables. Peel and chop the 3 large sweet potatoes into roughly 1-inch pieces so they cook evenly. Peel and chop the 3 large carrots into similar-sized pieces. Chop 3 bunches of broccoli (or 2 crowns) into florets, and slice or chop the 4 medium-sized zucchini into half-moons or chunks. Place the sweet potatoes and carrots in one large bowl, and put the broccoli and zucchini in a separate bowl—this helps account for differing roast times.
- Season the vegetables. In the bowl with sweet potatoes and carrots, drizzle 1 tablespoon of the avocado oil and sprinkle 2 Tbsp of the spices and herbs of choice (for the flavor I use, that’s ground cumin and a mix of dried basil and parsley). Add 1/2 tsp of the sea salt and a pinch of black pepper. Toss to coat evenly. In the bowl with broccoli and zucchini, drizzle another tablespoon of avocado oil, sprinkle the remaining 2 Tbsp of spices and herbs, add the remaining 1/2 tsp sea salt (you may reserve some salt to finish after roasting if you prefer), and season with a pinch more black pepper. Toss to combine.
- Distribute vegetables on baking sheets. Spread the sweet potato and carrot pieces on one baking sheet in a single layer, leaving space between pieces so they roast rather than steam. Spread the broccoli and zucchini on the other baking sheet, also in a single layer. If using three medium sheets, you can separate onions and garlic with one of the pan groups—see the next step.
- Sauté onion and garlic briefly. Heat the remaining 1 tablespoon of avocado oil in a skillet over medium heat. Add the finely chopped 1 medium yellow onion and sauté until it becomes translucent, about 4–5 minutes. Add the 5 cloves of minced garlic and cook for an additional 30–60 seconds until fragrant. Remove from heat and let cool slightly. You will add these aromatic pieces to the chicken so the flavors integrate during roasting.
- Prepare the chicken. Pat the 4 to 5 lbs boneless skinless chicken breasts dry with paper towels, then chop into bite-sized pieces. Place the chopped chicken in a large bowl. Add the sautéed onion and garlic to the chicken. Drizzle the chicken with a light splash of the reserved oil from the pan if desired, then sprinkle the same 4 Tbsp spices and herbs used on the vegetables over the chicken bowl—this keeps the flavor consistent. Season the chicken with the remaining salt and pepper to taste and toss everything until the chicken pieces are well coated.
- Add chicken to a baking sheet. Arrange the chopped chicken in a single layer on a third baking sheet or, if you have only two sheets, make space by combining one vegetable that cooks faster with the chicken. Ensure the chicken pieces are not piled on top of each other so they roast rather than steam. If your oven can fit all pans at once without crowding, place the chicken on the middle rack for even heat distribution.
- Roast the sweet potatoes and carrots. Place the baking sheet with sweet potatoes and carrots in the preheated oven. Roast for about 20 minutes, then check for tenderness by piercing a piece with a fork; continue roasting up to 30–35 minutes total if needed, until they are fork-tender and developing golden edges. If you notice edges browning too quickly, rotate the pan or reduce oven temperature by 10–15 degrees.
- Roast broccoli, zucchini, and chicken. Put the baking sheet with broccoli and zucchini into the oven and roast for 12–18 minutes, checking at the 12-minute mark; these vegetables should be tender-crisp with some browning. At the same time, place the chicken on its baking sheet in the oven and roast for 18–25 minutes, or until the chicken pieces are cooked through and reach an internal temperature of 165°F (74°C) if you check with a meat thermometer. If you roasted the chicken on the same sheet as a vegetable that cooks quickly, you may need to remove that vegetable earlier to avoid overcooking.
- Stagger pan times if needed. Because the sweet potatoes and carrots generally require more time than the broccoli, zucchini, and chicken, you can start the sweet potato sheet in the oven first and add the other pans a little later so everything finishes at roughly the same time. Check each pan toward the end of the cooking window and remove pans as they reach the desired doneness.
- Rest and finish. Once the chicken reaches 165°F and the vegetables are tender to your liking, remove all pans from the oven. Allow the chicken to rest for 5 minutes on the pan; this helps juices redistribute so the meat stays moist. While the chicken rests, you may sprinkle a little additional salt and pepper over the vegetables if you prefer more seasoning.
- Assemble meal prep containers. Divide the roasted sweet potatoes, carrots, broccoli, zucchini, and chopped chicken evenly among 4–6 meal prep containers. Aim for a balanced portion of protein and vegetables in each container. If you like, add a fresh squeeze of lemon, a handful of chopped fresh herbs, or a drizzle of extra avocado oil right before sealing the containers.
- Store and reheat. Let the containers cool to near room temperature before sealing and refrigerating. These meals will keep well in the refrigerator for 4–5 days. To reheat, warm in the microwave for 1–2 minutes, stirring once, or reheat on the stovetop in a skillet over medium heat until heated through. Add a splash of water or additional oil if needed to prevent sticking.
Serving suggestions
- Top with fresh herbs such as cilantro or parsley for brightness.
- Add a drizzle of lemon or lime juice for an extra zing before serving.
- Serve with a side salad or a simple tahini-style drizzle made from compliant ingredients if you want extra fat.
Storage and freezing
- Refrigerate: these prepped meals keep for 4–5 days in airtight containers.
- Freeze: for longer storage, place portions in freezer-safe containers and freeze for up to 3 months. Thaw overnight in the refrigerator before reheating.
- Reheating tip: if frozen, thaw in the refrigerator and reheat in a skillet to regain some roasted texture—microwaving works too for convenience.
Notes on ingredients and swaps
- If you can’t find avocado oil, use another neutral, high-heat oil suitable for roasting. Keep the same quantities.
- Spices are flexible—stick to the total of 4 Tbsp of dried spices and herbs combined to keep the flavor profile balanced and consistent with the recipe amounts.
- Maintain the listed amounts of salt and pepper, and adjust to taste at the end if you prefer more or less seasoning.
