This Lemon Garlic Chicken is the ultimate easy weeknight dinner with just minutes of hands-on prep and a quick marinating time! The chicken turns out juicy, flavorful, and perfectly balanced with zesty lemon, garlic, and herbs. Pair it with buttery potatoes and crisp broccoli for a complete sheet-pan meal everyone will love.
1½–2 lbs boneless skinless chicken thighs (or breasts – see notes)
1 lb baby Dutch potatoes, quartered (halved if very small)
3 cups broccoli florets
⅓ cup olive oil
3 cloves garlic, minced
3 Tbsp freshly squeezed lemon juice
2 tsp lemon zest
1 Tbsp Dijon mustard
1 tsp each: salt, pepper, dried basil, dried oregano, onion powder
½ tsp each: paprika, ground cumin, dried thyme, sugar
1 cup Greek yogurt or sour cream
¼ cup freshly grated Parmesan
¼ cup chopped parsley
1 Tbsp lemon juice
1 Tbsp chopped chives (optional)
1 Tbsp minced dill (optional)
¼ tsp salt
¼ tsp ground cumin
⅛ tsp pepper
Preheat the oven to 400°F (200°C). Line a large sheet pan (15×21″) with foil and lightly spray with cooking spray.
Marinate the chicken:
In a large resealable bag, combine all Lemon Garlic Marinade ingredients.
Remove 2 Tbsp of the marinade and set aside for the veggies.
Add chicken to the bag, seal, and toss to coat.
Let marinate 20 minutes at room temperature or up to 4 hours in the fridge.
Bake the potatoes:
Toss the potatoes with 1 Tbsp reserved marinade and ¼ tsp salt on the sheet pan.
Spread in a single layer and bake for 15 minutes.
Add broccoli and chicken:
Remove the pan and push potatoes to one side.
Add broccoli to the pan, toss with 1 Tbsp reserved marinade, and spread next to the potatoes.
Arrange the marinated chicken in a single layer on the other side.
Bake again:
Return to the oven and bake 17–22 minutes, or until chicken reaches:
170–175°F (for thighs)
165°F (for breasts or cutlets)
Make the sauce (optional):
While baking, whisk together all Parmesan Yogurt Herb Sauce ingredients in a small bowl.
Chill until ready to serve.
Serve:
Plate the chicken, potatoes, and broccoli together.
Drizzle with the yogurt sauce or serve it on the side for dipping.
Substitute chicken thighs with breasts or tenderloins — just adjust cook time as needed.
Try adding asparagus, green beans, or bell peppers for variety.
For a crispier finish, broil for 2–3 minutes at the end.
