Instructions

  1. Step 1: Preheat oven to 400°F (200°C). Pat chicken breasts dry, then season with 1/2 tsp sea salt, 1/4 tsp black pepper, 1 tbsp lemon zest, 2 minced garlic cloves, 1/2 tbsp rosemary, and 1/2 tbsp thyme. Drizzle with 1 tbsp olive oil and rub to coat evenly.
  2. Step 2: Arrange zucchini, bell pepper strips, and cherry tomatoes in a single layer on a baking sheet. Drizzle with remaining 2 tbsp olive oil, 1/4 tsp sea salt, and 1/8 tsp black pepper, then toss until evenly coated.
  3. Step 3: Place seasoned chicken on top of vegetables. Roast for 20-22 minutes until chicken reaches 165°F (74°C) internally and vegetables are tender with golden edges.

Frequently asked questions

Total time is about 37 minutes (15 min prep + 22 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 Lemon-Garlic Herb Chicken with Roasted Rainbow Vegetables?

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 breasts from drying out.

Can I substitute ingredients in Lemon-Garlic Herb Chicken with Roasted Rainbow Vegetables?

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 Lemon-Garlic Herb Chicken with Roasted Rainbow Vegetables 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 Lemon-Garlic Herb Chicken with Roasted Rainbow Vegetables?

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.
