Roasted Rosemary Potatoes make the flavor of crispy fingerlings sing, with plenty of butter, lemon juice, and rosemary for an easy, but crowd-pleasing starchy side dish.

Today we’re featuring the often dejected non-sweet potato, the fingerling potato. All non-sweet potatoes have gotten a pretty bad rap in recent years among us pursuing a Paleo lifestyle. As if by overnight sensation (kinda like that moment when you finally get double-unders), the collective Paleo crowd flipped a switch and decided that they’d come to the non-sweet potato’s defense. An avid all-potatoes-lover, I’m one of those people.

I make these roasted rosemary butter potatoes a lot. Like…a lot a lot. Every time I have company and I want a quick starchy side that is guaranteed to leave a smile on faces, I whip this simple little dish out. It takes minimal prep time but (thanks to a patient oven) results in wonderfully crispy and flavorful potatoes. I say this recipe serves 6 (as it probably should) but we’ve been known to take it down with just 4 people.

Fresh rosemary and the finishing lemon juice are the secrets to this flavorful dish. Don’t cut a corner and use dried rosemary…it just won’t be the same.

Serve these tasty spuds with our Slow Cooker Smothered Pork Chops, Crispy Bacon Wrapped Chicken Breasts, Grilled Skirt Steak, or Dill and Garlic Baked Salmon.

Step 1: In a large bowl, toss the potatoes, butter, 1 tablespoon of fresh rosemary, garlic powder, and sea salt together. Stir until each potato piece is evenly coated.

Step 2: Pour the mixture onto the lined baking sheet and spread out so that the potatoes are only one layer thick.

Bake at 350 F for one hour, checking towards the end to make sure that the potatoes around the edge don’t burn.

Recipe Tip

Baking sheet liners – lining your baking sheet with parchment paper (or a silicon baking mat) will make sor an easy cleanup. But if you’d like extra crispy potatoes, add a little extra butter or oil and leave the baking sheet unlined, which will results in crispier edges.

How to Serve

Once the potatoes are out of the oven, trasfer them to a serving bowl and toss with the fresh lemon juice and remaining 1 teaspoon of fresh rosemary.

How to Store and Reheat

Refrigerate leftovers in an airtight container for up to 5 days. Reheat until heated through and crispy in a 350 F oven.

Frequently Asked Questions

How are fingerling potatoes different from other potatoes?

Fingerling potatoes are long, slim, and knobby – which is how these “finger-like” potatoes got their name. Their flavor is earthy and nutty, and they come in a golden yellow, blue, and red varieties. 

Is it okay to eat green sprouted potatoes?

Are potatoes with a green tinge and sprouts safe to eat? That depends. If your spuds have a small amount of discoloration and small sprouts, you can get away with removing the offending green and sprouted bits, which have a bitter flavor. But if your potatoes are mushy and have a lot of discoloration and sprouts, pitch them since they can actually make you sick.
