My Crispy Roasted Potatoes are layers of thinly sliced russet potatoes scattered with shallots, slathered with butter and oil, and cooked until golden brown and delicious!

I can’t tell you how happy this Crispy Roasted Potatoes recipe makes BeeBop. He’ll be the first to admit that he is a big meat and potatoes fan and he has declared this recipe a huge success.

I mean really? Who wouldn’t love crispy potatoes flavored with butter, shallots, and a touch of lemon thyme? I have a pot of lemon thyme that grows like a weed in my herb bed, so I often use it instead of regular thyme. I love the flavor it adds to lots of recipes. So good.

❤️ Why We Love This Recipe

The crispy texture, of course! The combination of thinly sliced potatoes and the right balance of butter and oil creates a heavenly golden crust that’s irresistible.
It’s versatile – Serve these potatoes for a dinner party or a casual family meal as a complement to any main course. They pair perfectly with grilled meats, roasted chicken, or even as part of a vegetarian feast.
It’s customizable – I grow lemon thyme in my garden and always enjoy the citrusy-herby flavor it adds to recipes, but you can easily substitute it with regular thyme or experiment with other fresh herbs.

Butter and olive oil – This combination of fats gives rich flavor (from the butter) and protection from higher heat (from the olive oil).
Russet potatoes – You’ll want potatoes that are on the small-ish side. Yukon golds also work well.
Shallots – I really like the subtly different flavor of shallots. You can, however, substitute green onions if you want.
Lemon thyme – I know that lemon thyme can be difficult to source through your grocery store so feel free to use any fresh thyme that is available.

🔪 How to Make Crispy Roasted Potatoes

You’ll start off by melting the butter and adding the olive oil. Generously brush the bottom of the baking dish with some of the mixture. I chose to make this in my 10-inch cast iron skillet. You could use a gratin dish or any shallow 9 or 10-inch baking dish.

👉 PRO TIP: The only negative to this recipe is that you’ll need to peel four pounds of potatoes. Peeling potatoes is one kitchen chore that I just despise. I have to really love you to peel a potato for you. Even though I dislike doing it, I do think it makes for a much nicer finished recipe here. And once that bit of drudgery is out of the way, it’s easy-peasy from there on out.

If you have a mandoline and are not terrified of using it, you can cut your potatoes on it. Otherwise, use a sharp knife to cut each potato crosswise into thin slices. Try to keep the slices together as you go and as you finish each potato, place it intact into the pan.

Once you have all the potatoes snuggled nicely in place, peel and slice the shallots. Wedge the shallot slices randomly in between the sliced potatoes.

The final step is to brush on a delicious butter and olive oil mixture and season generously with salt and pepper. Then pop the pan into your 375-degree oven for an hour and 15 minutes. Go do whatever you want to, no stirring and no pot watching required!

Remove the pan from the oven and add the thyme springs to the top of the potatoes. Return the pan to the oven to cook for an additional 35 minutes or until the potatoes are golden brown on top and cooked through.

Add a little more fresh thyme right before serving if you like.

🍽️ How to Serve

These potatoes are the perfect choice to accompany a succulent grilled steak or a juicy roasted chicken. And they also shine as part of a hearty breakfast spread with steak and eggs.

🔀 Recipe Variations and Options

Change the seasoning by using a sprinkle of smoked paprika, some dried rosemary, garlic powder, or a pinch of cayenne pepper for a touch of heat.
Make them cheesy with a generous sprinkle of Parmesan during the last few minutes of baking.
Make a sweet version using small, thinly sliced sweet potatoes. Watch the cooking time carefully as they’ll take less time to cook than russets.

🍚 How to Store Leftovers

Store completely cooled leftovers in a sealed container in the refrigerator for up to 4 days. May be reheated in the oven at 350 degrees or in the microwave. When reheating, the texture will not be exactly the same as when freshly baked, but the flavors will still be delicious.
