Instructions

  1. Step 1: Preheat oven to 425°F. Toss sweet potato cubes with 1 tbsp olive oil, 1/4 tsp salt, and 1/8 tsp pepper. Spread in a single layer on a parchment-lined baking sheet and roast for 10 minutes.
  2. Step 2: Pat chicken thighs dry, then rub with remaining 1 tbsp olive oil, chopped rosemary, garlic powder, 1/4 tsp salt, and 1/8 tsp pepper.
  3. Step 3: After 10 minutes, remove baking sheet, add chicken thighs to the sheet (arranged around sweet potatoes), and return to oven. Roast for 25-30 minutes until chicken is cooked through and skin is golden and crisp.

Frequently asked questions

How long does Rosemary-Roasted Chicken Thighs with Sweet Potato take to make?

Total time is about 50 minutes (15 min prep + 35 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 Rosemary-Roasted Chicken Thighs with Sweet Potato?

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 Rosemary-Roasted Chicken Thighs with Sweet Potato?

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 Rosemary-Roasted Chicken Thighs with Sweet Potato 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 Rosemary-Roasted Chicken Thighs with Sweet Potato?

Mediterranean 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.
