  3. Step 3: Place chicken thighs on the baking sheet with the Brussels sprouts and roast for 35-40 minutes until the chicken is golden and the sprouts are crispy and tender.

Frequently asked questions

How long does Sheet Pan Chicken and Brussels Sprouts take to make?

Total time is about 55 minutes (15 min prep + 40 min cook). Most home cooks find this fits comfortably into a weeknight; double the batch on Sunday for two dinners.

How do I store leftover Sheet Pan Chicken and Brussels Sprouts?

Cool to room temperature within 2 hours, then store in an airtight container in the fridge for up to 4 days. Reheat covered in a 350°F oven for 10-12 minutes, or microwave at 70% power in 60-second bursts to keep chicken thighs from drying out.

Can I substitute ingredients in Sheet Pan Chicken and Brussels Sprouts?

Yes — most ingredients in this recipe have flexible swaps. For oil, use any neutral high-smoke-point oil (avocado, grapeseed, refined coconut). For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.

How do I scale Sheet Pan Chicken and Brussels Sprouts for a different number of people?

The recipe is written for 4 servings. Multiply each ingredient by (your serving target / 4). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.

What goes well with Sheet Pan Chicken and Brussels Sprouts?

American whole30 like this pair well with a compliant starch (roasted sweet potato, cauliflower rice, or plantains), a crisp salad dressed with olive oil and lemon, and sliced fruit. Skip grains, legumes, dairy and added sugar — none of them are Whole30-compliant. Tap "Plan a meal with the AI" to get specific side suggestions.
