Ingredients

Scale
  • 4 boneless, skinless chicken breasts (about 1.5 pounds / 680 grams)
  • 3 tablespoons olive oil (extra virgin if possible)
  • 2 cloves garlic, minced
  • 1 tablespoon lemon juice (freshly squeezed)
  • 1 teaspoon smoked paprika
  • 1 teaspoon dried oregano
  • ½ teaspoon ground black pepper
  • ½ teaspoon salt (adjust to taste)
  • 1 cup quinoa (dry; rinsed well before cooking)
  • 2 medium sweet potatoes, peeled and cubed
  • 1 head broccoli, cut into florets
  • 1 tablespoon olive oil (for roasting veggies)
  • Salt and pepper to taste
  • Optional toppings: fresh parsley or cilantro (chopped), red pepper flakes, lemon wedges, hummus or tzatziki

Instructions

  1. Marinate the Chicken (10 minutes active + 30 minutes resting): In a medium bowl, combine olive oil, minced garlic, lemon juice, smoked paprika, oregano, salt, and pepper. Add the chicken breasts and toss to coat evenly. Cover and refrigerate for at least 30 minutes (minimum 15 minutes if short on time).
  2. Preheat the Oven (5 minutes): Set oven to 425°F (220°C).
  3. Prepare the Veggies (10 minutes): Peel and cube sweet potatoes; cut broccoli into florets. Toss with olive oil, salt, and pepper in a large bowl.
  4. Cook the Quinoa (15-20 minutes): Rinse quinoa under cold water. In a medium saucepan, combine quinoa and 2 cups water. Bring to a boil, reduce heat to low, cover, and simmer about 15 minutes until water is absorbed. Fluff with a fork and set aside.
  5. Roast Chicken and Veggies (25-30 minutes): Arrange marinated chicken breasts on one side of a baking sheet. Spread sweet potatoes and broccoli on the other side in a single layer. Roast for 25-30 minutes until chicken reaches 165°F internal temperature and veggies are tender with crisp edges. Flip veggies halfway through cooking.
  6. Cool and Portion (10 minutes): Let cool slightly. Divide chicken, quinoa, and veggies evenly into 5 meal prep containers. Garnish with fresh parsley or cilantro if desired. Store in fridge up to 5 days.

Notes

Marinate chicken for at least 30 minutes to keep it juicy and flavorful. Rinse quinoa thoroughly to remove bitterness. Roast at high heat (425°F) for crispy edges without drying out chicken. Use airtight containers to maintain freshness. Quinoa can be cooked ahead or swapped with cauliflower rice for lower carbs. Use an instant-read thermometer to check chicken doneness. Reheat gently in microwave with a damp paper towel to retain moisture.
