Sheet pan chicken and vegetables is the simplest high-protein dinner you can batch: bite-sized chicken breast, baby potatoes, broccoli, peppers and red onion, tossed in oil and spices and roasted on one tray at 220°C (425°F). It makes four plates at about 530 calories and 58 grams of protein each. Hands-on time is around 15 minutes; the oven does the rest.
What you need
Serves 4. Prep 15 minutes, cook about 35 minutes. You’ll want two large rimmed baking sheets; one standard half-sheet is too crowded for this volume.
| Ingredient | Metric | Imperial |
|---|---|---|
| Boneless, skinless chicken breast, cut in 4 cm chunks | 900 g | 2 lb |
| Baby potatoes, halved | 680 g | 1½ lb (one bag) |
| Broccoli florets | 450 g | 1 lb (about 2 crowns) |
| Red and yellow bell peppers, chunked | 300 g | 2 peppers |
| Red onion, wedges | 150 g | 1 medium |
| Olive or canola oil | 30 ml | 2 tbsp |
| Smoked paprika, garlic powder, dried oregano, salt, pepper | 1 tsp each | 1 tsp each |
How to make it
- Heat the oven to 220°C (425°F) with both pans inside.
- Toss the potatoes with half the oil and a pinch of salt. Spread them on the hot pans, cut side down, and roast 15 minutes on their own. Potatoes need a head start; put everything in together and the chicken dries out before the potatoes soften.
- Meanwhile, toss the chicken, peppers, onion and broccoli with the rest of the oil and all the spices.
- Pull the pans out, add the chicken and vegetables in a single layer, and roast another 18 to 20 minutes, swapping the pans between racks halfway.
- Check the thickest chicken piece with a thermometer. Health Canada’s safe internal temperature for chicken pieces is 74°C (165°F).
- Squeeze a lemon over the tray and divide into four containers.
Macros per plate (approximate)
These numbers come from standard raw-ingredient values in USDA FoodData Central, divided by four. They assume all of the oil ends up on the plates.
| Calories | Protein | Carbs | Fat |
|---|---|---|---|
| about 530 | about 58 g | about 42 g | about 14 g |
Nearly all the protein is the chicken: 225 g raw per person is roughly 50 g on its own. If that portion is too big for your calorie target, use 600 g (1⅓ lb) of chicken and the plate drops to roughly 440 calories and 41 g protein.
Storing and reheating
Cool the tray for 20 to 30 minutes, portion it, and refrigerate. Health Canada’s leftover guidance is to eat refrigerated leftovers within 2 to 3 days or freeze them, so cook this on Sunday for Monday to Wednesday and freeze the fourth container. Reheat until steaming hot throughout. Broccoli doesn’t freeze well after roasting; in the frozen portion it turns soft but is still edible.
Swaps that change the dinner, not just the protein
- Greek-style: swap paprika for extra oregano and lemon zest, add a handful of olives (about 40 calories) and serve with tzatziki.
- Fajita tray: peppers and onions only, chili powder and cumin, no potatoes; serve in whole-wheat tortillas with salsa.
- Lower carb: replace the potatoes with cauliflower and zucchini. Plates drop by about 100 calories.
- Squash season: in October and November, butternut squash cubes replace the potatoes at a similar calorie count.
Fish fans should look at the salmon traybake, which uses the same one-tray idea with a shorter cook time. If you’d rather cook once for the whole week, slow cooker pulled chicken makes eight portions with almost no attention.
Why a tray dinner beats takeout on a Tuesday
The value here isn’t the recipe, it’s the decision you no longer have to make at 7 p.m. Four portioned containers in the fridge remove the two worst nights of the week from the takeout menu. If dinners like this keep falling apart by Thursday, a coach can build the week around your actual calendar; monthly coaching includes nutrition targets and the check-ins that keep the routine running.
Questions people also ask
Should I use chicken breast or thighs for sheet pan chicken?
Either works. Breast is leaner and gives the most protein per calorie. Boneless thighs stay juicier if you reheat leftovers and add about 1.5 g of fat per 100 g raw, so they suit you if dry chicken is what makes you skip the leftovers.
How do I keep the vegetables from getting soggy?
Use two pans if one is crowded, and leave space between pieces. Steam is what makes them soft. Preheating the empty pan for 5 minutes also helps the potatoes brown.
Can I make this with frozen chicken?
Thaw it first in the fridge overnight. Frozen pieces release water on the tray, steam the vegetables and cook unevenly, which makes it harder to hit a safe internal temperature everywhere.
