Chicken Stir-Fry Sheet Pan Meal

There’s something irresistibly satisfying about a vibrant stir-fry—crisp-tender vegetables, juicy pieces of chicken, a subtle nutty finish, and the whole sheet pan cleaned in minutes. This Chicken Stir-Fry Sheet Pan Meal takes the colors, textures, and flavors you love in a traditional stir-fry and simplifies them for a busy weeknight. Everything roasts together on one pan so you get the char and caramelization of a wok without standing over the stovetop. Ready in about 30–35 minutes, this is the dinner that’s equal parts speedy and impressive.

Why you’ll make this again and again

This recipe balances convenience and freshness. Cutting the chicken into at least 1-inch squares encourages even cooking and helps the pieces stay juicy. Roasting red bell peppers alongside sugar snap peas brightens the plate and keeps each vegetable crisp-tender. A light coating of peanut oil encourages golden edges and adds a toasty background note, and a finishing sprinkle of sesame seeds—black if you can find them—gives a beautiful, slightly bitter contrast to the sweet peppers.

Ingredients

• 3 boneless, skinless chicken breasts, trimmed and cut into pieces at least 1 inch square
• 2 red bell peppers
• 2 cups sugar snap peas
• 1 1/2 T peanut oil
• 1-2 T sesame seeds, preferably black

Equipment

• Large rimmed sheet pan
• Sharp chef’s knife and cutting board
• Mixing bowl or shallow dish for tossing chicken and vegetables
• Measuring spoons
• Tongs or a spatula

Prep tips before you start

Preheat the oven so the sheet pan hits high heat immediately—this builds a nice roast on the chicken and vegetables. Trim any excess fat from the chicken and aim for uniform pieces at least 1 inch square so everything finishes at the same time. If your red bell peppers are large, slice them into strips roughly 3/4 inch wide; the goal is similar thickness between vegetables and chicken pieces for even roasting. Pat the chicken dry before tossing with oil to encourage browning.

Flavor notes and substitutions

This straightforward ingredient list allows the natural flavors to sing. If you want a boost of spice, add a pinch of crushed red pepper flakes before roasting. For a gluten-free plate, pair this sheet pan meal with steamed rice or a warm grain of your choice. If peanut oil is unavailable, you can substitute another mild oil with a high smoke point—such as sunflower or avocado oil—keeping the quantity the same.

Step-by-step directions

Follow these steps in order for a perfectly roasted Chicken Stir-Fry Sheet Pan Meal. The directions have been rewritten for clarity while keeping the order and ingredient amounts unchanged.

1. Preheat your oven to 425°F (220°C). Place a large rimmed sheet pan in the oven while it heats to help the pan get hot and promote quick browning.
2. Trim the chicken breasts and cut them into pieces at least 1 inch square. Pat the pieces dry with paper towels to remove excess moisture—this helps them brown.
3. Wash and dry the red bell peppers. Remove the stems, seeds, and membranes, then slice each pepper into strips roughly 3/4 inch wide so they cook evenly with the chicken.
4. Rinse the sugar snap peas and trim the stem ends if needed. Keep them whole; they will roast quickly and should remain crisp-tender.
5. Place the chicken pieces in a large mixing bowl or shallow dish. Add 1 1/2 tablespoons of peanut oil and toss the chicken until every piece is lightly coated. The oil will help the chicken brown on the hot sheet pan.
6. Transfer the oiled chicken pieces to the preheated sheet pan, spreading them into a single layer so there’s space around each piece. If your pan is crowded, use a second sheet pan or roast in batches to avoid steaming.
7. Add the sliced red bell peppers and the sugar snap peas to the sheet pan. Arrange the vegetables so they’re in a single layer alongside the chicken pieces, keeping the pan surface as open as possible for even roasting.
8. Place the sheet pan in the preheated oven. Roast for approximately 12–18 minutes, depending on the size of your chicken pieces and your oven. Halfway through the cook time—around the 7–9 minute mark—use tongs or a spatula to gently turn the chicken and give the vegetables a quick toss so they brown evenly on all sides.
9. Continue roasting until the chicken reaches an internal temperature of 165°F (74°C) and shows no pink in the center, and the red bell peppers and sugar snap peas are tender-crisp with a few browned edges. Thin or small pieces may cook faster, so check the chicken early to avoid overcooking.
10. Remove the sheet pan from the oven and let everything rest for 2–3 minutes. Sprinkle 1–2 tablespoons of sesame seeds—black sesame seeds if available—over the chicken and vegetables while they’re still warm so the seeds stick and release their aroma.
11. Serve the Chicken Stir-Fry Sheet Pan Meal immediately, straight from the pan or transferred to a warmed platter. It pairs beautifully with steamed rice, noodles, or a simple green salad for a complete meal.

Serving suggestions

For an easy weeknight dinner, serve this Chicken Stir-Fry Sheet Pan Meal over fluffy jasmine rice or brown rice. If you prefer noodles, toss hot cooked rice noodles with a splash of soy or tamari and spoon the roasted chicken and vegetables over the top. Fresh lime wedges, a drizzle of your favorite chili oil, or a handful of chopped scallions add brightness at the table. The black sesame seeds add visual contrast and a toasty finish—if you don’t have black sesame seeds, white sesame seeds are a fine alternative.

Storage and reheating

Store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, spread the chicken and vegetables in a single layer on a sheet pan and warm in a 350°F (175°C) oven for 8–10 minutes, or microwave in short bursts until heated through. Reheating in the oven helps maintain crisp edges more effectively than the microwave.

Make-ahead tips

You can cut the chicken and slice the peppers a day in advance for faster assembly. Keep the trimmed and cut chicken in a covered container in the fridge and the sliced peppers in a separate container. When ready to cook, toss the chicken with the oil and proceed with roasting. Do not salt the chicken in advance if you plan to store it more than a few hours, as salt can draw moisture out and affect texture.

Notes on ingredients

Be sure the chicken breasts are trimmed of excess fat and any membrane before cutting to pieces at least 1 inch square. Sugar snap peas cook quickly and retain a pleasing crunch when roasted at high heat, so add them directly to the pan without parboiling. Use peanut oil for its high smoke point and slight nuttiness; if that’s not available, choose a neutral oil with a similar tolerance for heat.

Nutrition snapshot (approximate per serving)

This depends on portion size and sides, but a generous serving of roasted chicken and vegetables like this is typically high in protein, moderate in healthy fats from the cooking oil, and low in added sugars. Pair with whole grains or a salad for balanced nutrition.
