Ingredients
3 Large Russet Potatoes
Russet potatoes are ideal because their naturally starchy interiors become soft and fluffy as they cook. Keeping the skins on gives the potato spears a rustic texture and helps them hold their shape better during slow cooking.
Scrub the potatoes thoroughly before cutting them, especially because the skins remain intact.
1 Packet Dry Onion Soup Mix
Dry onion soup mix provides most of the seasoning in this simple recipe. It brings savory onion flavor, salt, herbs, and seasoning to every potato spear without requiring a long list of individual spices.
Sprinkle it as evenly as possible so every bite gets plenty of flavor.
1/2 Cup Unsalted Butter, Melted
Melted butter adds richness and helps coat the potatoes and seasoning. As the potatoes cook, the butter creates a flavorful coating that complements their earthy, starchy texture.
Using unsalted butter gives you a little more control over the overall saltiness because the onion soup mix already contains seasoning.
How to Make 3-Ingredient Slow Cooker Amish Potatoes
Step 1: Prepare the Potatoes
Scrub the russet potatoes thoroughly under cool running water. Pat them dry, then cut each potato lengthwise into thick spears.
There is no need to peel them. The skins are part of what gives this dish its rustic, old-fashioned appeal.
Step 2: Add Everything to the Slow Cooker
Place the potato spears directly into the slow cooker.
Drizzle the melted butter evenly over the potatoes, then sprinkle the dry onion soup mix over the top. Gently toss everything together until the potato pieces are coated as evenly as possible.
Step 3: Slow Cook Until Tender
Cover the slow cooker and cook on LOW for 5 to 6 hours or HIGH for 2 1/2 to 3 1/2 hours.
If convenient, gently stir the potatoes once or twice during cooking. Be careful not to over-stir, since very tender potato spears can begin to break apart.
The potatoes are ready when they are fork-tender and lightly browned around the edges.
Step 4: Serve Hot
Carefully transfer the finished potatoes to a serving platter.
Serve them immediately while they are hot, buttery, and fragrant. Spoon any flavorful buttery seasoning left in the slow cooker over the potatoes for even more flavor.
Pro Tips for Perfect Slow Cooker Potato Spears
Cut the potatoes evenly. Try to make the spears approximately the same thickness. This helps them cook at roughly the same rate.
Do not peel the potatoes. Thoroughly scrubbed potato skins add rustic texture and help the spears maintain their shape.
Avoid excessive stirring. Once the potatoes become tender, too much stirring can cause them to fall apart.
Use enough room in the slow cooker. If the crock is packed extremely tightly, the potatoes may cook less evenly. For a larger gathering, use a sufficiently large slow cooker rather than piling everything into a small one.
Want extra browning? Once the potatoes are tender, transfer them to a baking sheet and place them under the broiler for 2 to 4 minutes. Watch them closely because they can brown quickly.
Taste before adding extra salt. The dry onion soup mix is already seasoned, so additional salt may not be necessary.
Easy Variations
Add Fresh Herbs
Finish the hot potatoes with fresh parsley, chives, or dill. The fresh herbs add brightness and a pop of color without taking away from the simple character of the dish.
Make Them Cheesy
For an extra-indulgent version, sprinkle shredded cheddar cheese over the cooked potatoes while they are still hot. Cover briefly and allow the cheese to melt.
Add Garlic
If you enjoy a stronger savory flavor, add a little garlic powder or minced garlic before cooking.
Give Them Extra-Crispy Edges
For potatoes with beautifully browned edges, use the slow cooker for tenderness and then finish the potatoes under the broiler. This gives you the best of both worlds: soft, fluffy centers and crisp, buttery edges.
What to Serve With Slow Cooker Amish Potatoes
These potatoes are versatile enough to accompany almost any comforting main course.
Serve them alongside roast chicken, grilled sausage, meatloaf, burgers, pork chops, or baked ham for a hearty dinner.
For a cozy breakfast-for-dinner meal, pair them with scrambled eggs, breakfast sausage, bacon, and toast.
If you’re serving them at a potluck or family gathering, balance the richness with lighter sides such as:
– Crisp green salad
– Creamy coleslaw
– Steamed green beans
– Roasted vegetables
– Pickles or relish
– Fresh dinner rolls
For an old-fashioned finishing touch, offer sour cream or applesauce alongside the potatoes.
Frequently Asked Questions
Can I leave the potato skins on?
Yes. In fact, the skins are part of the appeal of this rustic slow cooker potato recipe. Just make sure the potatoes are scrubbed very well before cutting.
Can I use a different type of potato?
Yes, although russet potatoes are especially good here because they become fluffy and tender. Yukon Gold potatoes can also work and will provide a naturally buttery texture.
Can I prepare these potatoes ahead of time?
You can wash and cut the potatoes ahead of time. To prevent them from discoloring, keep the cut potatoes submerged in cold water, then drain and dry them thoroughly before cooking.
How do I make the potatoes crispier?
The easiest method is to finish the cooked potatoes under the broiler for 2 to 4 minutes. Spread them in a single layer on a baking sheet and watch them carefully as they brown.
