Lemon Herb Chicken Thighs with Crispy Smashed Potatoes (The Best Friday Night Dinner)
My oldest could not stop picking at this before it even made it to the table.
That is the highest compliment I know in my house. When someone cannot wait for dinner and keeps sneaking pieces straight from the pan you know you have made something really special.
This lemon herb chicken thighs with crispy smashed potatoes recipe is genuinely one of the best chicken dishes I have ever made. And I have made a lot of chicken.
The marinade is everything. Fresh rosemary, fresh lemon zest, loads of garlic, and smoked paprika pressed right into the skin of bone-in chicken thighs. That skin comes out of the oven deeply golden and incredibly crispy. And the smashed potatoes. There is something so satisfying about pressing down on a boiled potato and feeling that skin burst under your hand. Then they go into a hot oven with olive oil and minced garlic until the edges are golden and crunchy and the insides are fluffy and soft.
My family gave this a 10 out of 10. That does not happen often. Make this on a Friday. Your family deserves it at the end of a long week.

INGREDIENTS:
For the chicken:
- 6 to 8 bone-in skin-on chicken thighs
- 2 tsp salt
- 2 tsp black pepper
- 2 tsp garlic powder
- 1 tsp dried oregano
- 1 tsp smoked paprika
- Zest of 2 lemons
- 3 tbsp fresh lemon juice
- 6 cloves garlic, minced
- 3 tbsp olive oil
- 3 tbsp fresh parsley, chopped
- 2 tbsp fresh rosemary, finely chopped
For the crispy smashed potatoes:
- 2.5 lbs small gold or baby potatoes
- 4 tbsp olive oil
- 6 cloves garlic, minced
- 2 tsp salt
- 1 tsp black pepper
- 1 tsp garlic powder
- 2 tbsp fresh parsley, chopped
- Freshly grated Parmesan for finishing
To serve:
- Extra fresh lemon wedges
- Extra fresh parsley
- Flaky sea salt for finishing
A note on the chicken: Bone-in skin-on chicken thighs are essential for this recipe. The bone keeps the meat incredibly juicy and the skin gets deeply golden and crispy in a way that boneless thighs simply cannot achieve. Plan for 35 to 40 minutes of total cook time in the oven.
A note on the potatoes: Small gold or baby potatoes work best here. They boil faster and smash more evenly than large potatoes. The key is boiling them completely through before smashing. Undercooked potatoes will not smash properly and will not get crispy. Cook them longer than you think you need to.
A note on the rosemary: Fresh rosemary is non-negotiable in this recipe. Dried rosemary is too harsh and woody for a marinade. Fresh rosemary finely chopped melts into the marinade and gives you that incredible herby flavor without being overpowering.
HOW TO MAKE LEMON HERB CHICKEN THIGHS WITH CRISPY SMASHED POTATOES:
Step 1 — Boil the potatoes
Place potatoes in a large pot of heavily salted cold water. Bring to a boil and cook until completely fork tender all the way through. This takes longer than you might expect — plan for 20 to 25 minutes depending on size. You should be able to pierce them easily with no resistance. Drain completely and let steam dry for 5 minutes. Dry potatoes get crispier potatoes.
Step 2 — Make the marinade
Combine olive oil, minced garlic, lemon zest, fresh lemon juice, dried oregano, smoked paprika, finely chopped fresh rosemary, and fresh parsley in a bowl. Stir well. This marinade smells absolutely incredible and that smell only gets better in the oven.
Step 3 — Season and coat the chicken
Season chicken thighs generously on both sides with salt, black pepper, and garlic powder. Spoon the herb marinade over both sides pressing it firmly into the skin with your hands. Make sure every inch of the skin is coated.
Step 4 — Preheat oven to 425 degrees F
A very hot oven is what gives you crispy chicken skin and golden smashed potatoes. Do not go lower.
Step 5 — Smash the potatoes
Place boiled potatoes on a large generously oiled sheet pan. Use the bottom of a heavy glass or a potato masher to firmly press each potato flat to about half an inch thick. This is the most satisfying step of the entire recipe. You feel the skin burst under your hand and the potato flattens out into a crispy edged disk. Drizzle generously with olive oil. Season with salt, pepper, and garlic powder. Scatter minced garlic over each potato.
Step 6 — Roast the potatoes first
Roast smashed potatoes at 425 degrees F for 25 to 30 minutes until the edges are deeply golden and crispy. Check them at 20 minutes and add more time if needed. You want real crispiness on those edges not just a light golden color.
Step 7 — Add chicken to the oven
Place marinated chicken thighs on a separate sheet pan or large oven-safe skillet skin side up. Add chicken to the oven when the potatoes have been roasting for about 20 minutes. Roast chicken for 35 to 40 minutes until the skin is deeply golden and crispy and the internal temperature reaches 165 degrees F at the thickest part near the bone. Do not rush this. Bone-in chicken thighs need the full time.
Step 8 — Finish and serve
Remove both from the oven. Immediately finish the potatoes with freshly grated Parmesan and chopped parsley while still hot. Squeeze fresh lemon juice over the chicken and finish with extra parsley. Serve together with extra lemon wedges and flaky sea salt on the table.
TIPS FOR THE BEST LEMON HERB CHICKEN THIGHS WITH CRISPY SMASHED POTATOES:
Boil the potatoes completely through. More done than you think necessary. Undercooked potatoes will not smash flat and will not get crispy in the oven.
Let the potatoes steam dry after boiling. Five minutes out of the pot before smashing. Moisture is the enemy of crispiness.
Be extremely generous with olive oil on the smashed potatoes. That oil is what makes the edges golden and crispy. Do not skimp.
Press the marinade firmly into the chicken skin with your hands. You want every inch covered. The more contact the better the flavor.
Plan for 35 to 40 minutes of oven time for the chicken. Bone-in skin-on thighs need the full time to cook through properly and develop that crispy skin. Check internal temperature at 35 minutes.
Finish the potatoes with Parmesan immediately out of the oven while they are still hot. The cheese melts into the crispy edges and it is absolutely incredible.
The lemon squeeze over the chicken right before serving brightens everything up. Do not skip it.
VARIATIONS:
Swap the rosemary for fresh thyme. Equally incredible and slightly more subtle in flavor.
Add cherry tomatoes to the potato sheet pan in the last 15 minutes of roasting. They burst and caramelize and become something magical alongside the crispy potatoes.
Use boneless skinless chicken thighs for a faster version. Reduce oven time to 20 to 25 minutes. The skin will not be as crispy but the flavor from the marinade is still outstanding.
Add asparagus to the sheet pan in the last 12 minutes of roasting for a complete one pan meal.
Finish with a drizzle of good quality olive oil and flaky sea salt right before serving. This small detail elevates the whole dish significantly.
HOW TO STORE AND MEAL PREP:
Refrigerator: Store chicken and potatoes separately in airtight containers for up to 4 days.
Reheat chicken: In a 375 degree F oven for 10 to 12 minutes until heated through and skin re-crisps. Avoid the microwave for the chicken as it makes the skin soggy.
Reheat potatoes: In a hot skillet with a drizzle of olive oil for 3 to 4 minutes until edges crisp back up. Or in a 400 degree F oven for 8 minutes. The microwave works but you will lose the crispiness.
Meal prep tip: Boil and smash the potatoes the day before. Store on the sheet pan covered in the fridge. The next day drizzle with olive oil, season, and roast. This saves significant time on a busy weeknight.
FAQ:
Bone-in skin-on chicken thighs always take longer than boneless. Plan for 35 to 40 minutes of oven time minimum. Always check internal temperature with a meat thermometer at the thickest part near the bone. 165 degrees F is your target.
Yes. Reduce oven time to 20 to 25 minutes. The flavor from the marinade will still be incredible but you will not get the same crispy skin result.
You can but chicken breasts dry out more easily than thighs. If using breasts reduce oven time and check temperature at 20 minutes. Pull at 160 degrees F and let rest as they will carry over cook to 165.
Two most common reasons. Either the potatoes were not boiled completely through before smashing or there was not enough olive oil on the sheet pan. Both are essential for crispy edges.
I strongly recommend against it for this recipe. Dried rosemary is too woody and harsh in a marinade. Fresh rosemary finely chopped is what gives you that incredible herby flavor. It is worth buying fresh.
Yes. Make the marinade up to 24 hours ahead and store in the fridge. You can also marinate the chicken overnight for even more flavor.
Small gold or baby potatoes. They boil faster and smash more evenly. If using larger potatoes cut them in half before boiling so they cook through faster.
Approximately 42 to 46 grams of protein per serving. One of the highest-protein dinners in my weekly rotation.
Yes. The entire recipe is naturally gluten-free.
