Dill Butter Fingerling Potatoes: Easy Slow Cooker Side Step-by-step instructions

Before you start

Wash the fingerling potatoes thoroughly and pat them dry; no need to peel. Mince the garlic, zest the lemon, and chop the fresh dill. Cut the butter into small cubes so it melts quickly and coats the potatoes evenly.

Have the slow cooker ready on the counter. Measure out the lemon juice and set the flaky salt nearby for the final step. Everything can be prepped in about 10 minutes, and then the slow cooker takes over.

Instructions

Layer and Set

1. 1Layer the ingredients
   Place the washed fingerling potatoes in the slow cooker. Scatter the cubed butter over the top, then add the minced garlic, lemon zest, and chopped fresh dill. Stir gently with a spoon so the butter and herbs coat the potatoes as evenly as possible.
   Look for Potatoes are coated with butter, garlic, lemon zest, and dill.
   Tip No need to peel fingerlings; the skins hold up beautifully during slow cooking.
2. 2Cover and set the slow cooker
   Place the lid securely on the slow cooker. Set the temperature to LOW. Do not add any liquid; the potatoes will release their own moisture and cook in the butter and seasonings.
   Look for Lid is sealed and the slow cooker is set to LOW.
   Tip Resist the urge to peek often; each lid lift lets out heat and extends cooking time.

At the end of this phase, the slow cooker is filled with potatoes coated in butter, garlic, lemon zest, and dill. The butter is still solid in places, but the aromatics are distributed. The slow cooker is set to LOW and the lid is on. There is no liquid added, and the potatoes look dry but well seasoned. This is the starting point; from here, the slow cooker works its magic.

Slow-Cook and Transform

3. 3Slow-cook the potatoes
   Cook on LOW for 4 hours, undisturbed. The potatoes are done when the skins wrinkle slightly and a fork or paring knife slides into the flesh with no resistance. The butter should look creamy and slightly thickened from the potato starch.
   Look for Skins are wrinkled and a fork pierces the potatoes easily.
   Tip If your slow cooker runs hot, check at 3 1/2 hours; if it runs cool, give it up to 4 1/2 hours.

After 4 hours, the potatoes have transformed. The skins are wrinkled and slightly glossy, and the butter has melted into a creamy, herb-flecked sauce. The garlic and dill are fragrant, and the potatoes yield easily to a fork.

The sauce is not watery but has a light, silky texture. The potatoes hold their shape but are tender all the way through. The slow cooker smells warm and savory.

Finish and Serve

4. 4Finish with lemon and salt
   Once the potatoes are tender, squeeze the fresh lemon juice over the top and toss gently to coat. Sprinkle with flaky sea salt right before serving. Scoop the potatoes into a serving dish and spoon any remaining lemon dill butter from the slow cooker over the top.
   Look for Potatoes glisten with butter and herbs, and the lemon adds brightness.
   Tip Add the flaky salt at the table if serving later; it stays crunchier that way.

The lemon juice and flaky salt are added just before serving. The potatoes are glistening with butter and herbs, and the lemon brightens the rich flavor. The flaky salt adds a crunchy, salty pop that contrasts with the creamy potatoes. Scoop them into a serving dish and spoon any extra butter sauce over the top. They are ready to go to the table, warm and fragrant.

Common mistakes

One common mistake is adding water or broth to the slow cooker. The potatoes release enough moisture on their own, and extra liquid will make them waterlogged instead of buttery.

Another is lifting the lid too often; every peek lets out heat and extends the cooking time. Finally, do not overcook. While the potatoes are forgiving, leaving them for 6 hours or more can turn them mushy and cause the skins to split. Stick to the 4-hour mark.

How to tell it’s done

The potatoes are done when the skins wrinkle slightly and a fork or paring knife slides into the flesh with no resistance. The butter will look creamy and slightly thickened from the potato starch.

The aroma will be intensely buttery with fresh dill and garlic. If the potatoes are still firm after 4 hours, continue cooking in 15-minute increments until tender. There is no protein in this recipe, so no internal temperature check is needed.
