Instructions

  1. Step 1: Preheat oven to 425°F. Pat chicken thighs dry with paper towels, then rub with 1 tbsp olive oil, 1/2 tsp dried rosemary, 1/2 tsp dried thyme, 1/4 tsp garlic powder, 1/4 tsp salt, and 1/8 tsp black pepper.
  2. Step 2: Cut carrots and parsnips into 1/2-inch cubes. Arrange in a single layer on a baking sheet. Season with remaining 1/2 tsp dried rosemary, 1/2 tsp dried thyme, 1/4 tsp garlic powder, 1/4 tsp salt, and 1/8 tsp black pepper.
  3. Step 3: Place seasoned chicken thighs atop the vegetables. Roast for 35-40 minutes, or until chicken reaches 165°F internal temperature and vegetables are fork-tender.
  4. Step 4: Let rest 5 minutes before serving to allow juices to redistribute.

Can I substitute ingredients in Herb-Roasted Chicken Thighs with Carrot-Parsnip Medley?

How do I scale Herb-Roasted Chicken Thighs with Carrot-Parsnip Medley for a different number of people?

The recipe is written for 2 servings. Multiply each ingredient by (your serving target / 2). 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.

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.
