Garlic Parmesan Chicken Thighs and Potatoes | Easy One-Pan

Let me tell you something. Some dinners just feel like a warm hug after a long day.

This is one of them.

Garlic Parmesan Chicken Thighs and Potatoes is the kind of meal that makes your whole house smell incredible. It is one pan, minimal cleanup, and delivers the sort of rich, savory flavor you would expect from a restaurant. Not a weeknight scramble.

The real secret? A creamy marinade made with mayonnaise and Dijon mustard. I know, I know. It sounds a little unexpected. But trust me on this one. That combo keeps the chicken incredibly tender while helping the skin turn into this gorgeous, golden crust that crackles when you cut into it.

And the potatoes? They roast right underneath the chicken thighs, soaking up every single drop of those savory pan drippings. They basically season themselves.

Before We Start: A Few Ingredient Notes

You probably already have most of this stuff in your pantry. Sweet paprika, garlic powder, onion powder — these three build a solid, savory flavor base before anything else even happens.

Then we layer in freshly chopped garlic and a little lemon zest for brightness. And at the very end, freshly grated Parmesan and chopped dill take the whole thing over the top.

A couple of ingredient tips worth knowing:

• Yukon Gold potatoes are the move here. They have a naturally buttery texture and thin skin, so you do not even need to peel them. Just wash, cube, and go.
• Diamond Crystal kosher salt is what I use in this recipe. It seasons food evenly without going overboard.

Recipe at a Glance

Most of that time is completely hands-off. You will spend maybe 15 minutes actually doing things. The oven does everything else.

How to Make It

Step 1: Preheat the Oven

Set your oven to 350 degrees Fahrenheit.

I know that feels low. But this moderate heat is exactly what bone-in chicken thighs need. It lets the meat cook through slowly and gently while giving the potatoes enough time to get tender. Crank the heat too high too fast and you risk burning the skin before the inside is even close to done.

Slow and steady wins this one.

Step 2: Season the Potatoes

Grab a large mixing bowl and toss in your cubed Yukon Gold potatoes. Add the paprika, garlic powder, onion powder, and kosher salt. Use your hands and toss everything together until every single cube is coated.

Now spread them in a single, even layer in your baking dish.

One important thing here: do not overcrowd the pan. Potatoes need space. Stack them up and they will steam instead of roast. You want tender insides with those beautifully flavored edges, not a soggy pile.

Step 3: Coat the Chicken

In a separate large bowl, add your six bone-in, skin-on chicken thighs. Now build the marinade directly on top of them.

Add:

• The mayonnaise and Dijon mustard
• Finely chopped garlic
• Lemon zest and fresh lemon juice
• Garlic powder, onion powder, Italian seasoning
• Kosher salt, sweet paprika, and black pepper

Use your hands or a pair of tongs and toss until every thigh is heavily, evenly coated. Do not be shy about it. You want thick coverage all over.

The mayonnaise is doing a lot of work here. It grabs onto all the dry spices and locks them in place. It keeps the meat moist during the long bake. And it is what gives you that crackly, golden skin at the end.

You will not taste the mayo. It just quietly transforms into something magical.

Step 4: Assemble and Bake

Place the coated chicken thighs directly on top of the seasoned potatoes. Rest them skin-side up so the juices drip straight down into the potato layer below.

This is where the dish really comes together. Those drippings season the potatoes in a way no spice blend ever could.

Slide the uncovered dish into the oven and bake for 60 to 75 minutes.

Use an instant-read thermometer to check the chicken. Insert it into the thickest part of the thigh, away from the bone. You are looking for 165 degrees Fahrenheit. Poke a fork into the potatoes to make sure they are soft all the way through.

Step 5: Crisp the Skin

Once the chicken is cooked through, bump the oven temperature up to 400 degrees Fahrenheit. Let it go for a few more minutes, just until the skin deepens into that gorgeous golden-brown finish.

Watch it closely. This step moves fast.

Step 6: Finish and Serve

Pull the dish out of the oven carefully. Now the finishing touches:

• Sprinkle freshly grated Parmesan evenly over the top
• Scatter the chopped fresh dill across the pan
• Squeeze the reserved lemon half over everything

That hit of citrus at the end cuts right through the richness. It balances the whole dish in a way that just makes sense.

Plate a chicken thigh with a generous scoop of potatoes, spoon some of those pan juices over the top, and let it rest for just a minute before digging in.

Frequently Asked Questions

Can I use boneless, skinless chicken thighs instead?

You can. But they cook much faster than bone-in pieces, so the timing needs to change.

Here is what I recommend: roast the potatoes alone for about 30 minutes first. Then add the coated boneless thighs and bake everything together for another 25 to 30 minutes. Check that internal temperature and pull them as soon as they hit 165 degrees.

Will the potatoes stick to the bottom of the pan?

They might, especially if the dish is bone dry going in. The mayo marinade drips down and provides plenty of cooking fat, but for extra insurance, lightly brush the bottom of the baking dish with olive oil before adding the potatoes. It also makes cleanup so much easier later.

How do I get crispier potatoes?

This recipe gives you soft, flavor-soaked potatoes. They are silky and rich because they cook underneath the chicken the whole time.

If you want crispy potatoes, here is the trick: parboil the cubed potatoes in salted water for five minutes first. Drain them really well, rough up the edges a little, then roast them in a separate pan. They will get nicely browned and crispy on their own, away from all that moisture.

Can I prep this dish ahead of time?

Yes, partly. You can marinate the chicken overnight in the fridge. The flavors actually get deeper and more pronounced the longer it sits.

Do not cut the potatoes ahead of time though. Raw potatoes oxidize quickly and turn an unappetizing brown color. Cut them fresh, right before you are ready to assemble and bake.

Do I really need the mayonnaise?

I really do recommend keeping it. The mayo acts as a sticky binder that holds all the spices in place. It also stops the skin from drying out during the long roast.

The good news? You will not taste it at all. It completely transforms during baking.

That said, if you need to substitute, full-fat Greek yogurt works as a decent alternative. Not quite the same result, but it gets you close.

How do I store and reheat leftovers?

Store leftovers in an airtight container in the fridge for up to three days.

When reheating, skip the microwave. It makes the skin soft and rubbery. Instead, reheat in the oven or air fryer at 350 degrees Fahrenheit until warmed through. The skin crisps right back up and it tastes almost as good as day one.

This is the kind of dinner that earns a spot in the weekly rotation fast. It is simple, it is deeply satisfying, and it never disappoints. Make it once and you will understand exactly why it is one of my favorites.

Toppings & Finishing

• 4 ounces Parmesan cheese freshly grated, about 1 cup

• In a separate bowl, coat the chicken thighs with mayonnaise, Dijon mustard, chopped garlic, lemon zest, lemon juice, and all the remaining dry spices. Ensure every piece is heavily and evenly coated.
• Place the coated chicken thighs skin-side up directly on top of the potatoes. Bake uncovered for 60 to 75 minutes, or until the internal temperature of the chicken reaches 165°F and potatoes are soft.
• Bump the oven temperature to 400°F for a few minutes to crisp the skin until it is a deep golden-brown. Watch closely.

Notes

For extra insurance against sticking, lightly brush the baking dish with olive oil before adding the potatoes. If substituting with boneless thighs, roast potatoes alone for 30 minutes before adding the chicken.
