Prep Notes & Tips

There’s no need to peel the Russet potatoes first, as the skin helps these potatoes stay intact during the cooking process.

Isn’t that such an easy prep win?

And if you’re looking for a super crispy slow cooker roasted potatoes, just pop the potatoes under the broiler for about 5 minutes after they’ve cooked to achieve that golden brown crispy result.

When it comes to making these ahead, I personally do not find that these potatoes reheat well, so it’s best to make them the day you want to eat them for best results.

Tip: Russet potatoes can become gummy when overcooked in a slow cooker. For this reason, I do not recommend holding these potatoes on warm after the initial cook time.

Key Ingredients and Substitutions

Olive oil: Substitute melted butter to take these over the top, or reduce the oil to 1 tablespoon for a lighter version.

Russet potatoes: Essential for this recipe, try Slow Cooker Potatoes if you want a version with red potatoes or yellow potatoes.

Garlic: I love the hit of flavor fresh garlic adds, but you can use 2 teaspoons granulated garlic powder if you prefer.

Fresh herbs: Feel free to use what you like or have on hand. I love fresh rosemary, but parsley, chives, and thyme also work well.

Parmesan: Try to use freshly grated parmesan if you can. You can also use more than called for in the recipe for an even cheesier version, or skip the parmesan for a dairy-free and vegan version.

Why Make Potatoes in the Slow Cooker

There are a number of reasons you might want to cook roasted potatoes in the slow cooker rather than the oven.

For the holidays like Thanksgiving, cooking potatoes in the slow cooker can save precious oven space for other dishes.

Or, during the hot months of summer, cooking potatoes in the slow cooker will help keep the kitchen cool.

Finally, cooking the potatoes in the crockpot can be handy when bringing the dish to potlucks or to a friend’s house.

Ingredients

  • 2 tablespoons olive oil
  • 2 ½ pounds russet potatoes, sliced into 2-inch pieces, about 6 medium
  • 1 teaspoon kosher salt, divided 
  • 4 garlic cloves, minced or finely grated

To Add at the End

  • 2 tablespoons fresh herbs, such as parsley, chives, rosemary, or thyme
  • ⅓ cup freshly grated parmesan cheese
  • freshly ground pepper, to taste

Equipment

Instructions 

  • Add the olive oil, potatoes, ½ teaspoon salt, and garlic to a 6-quart slow cooker, tossing to coat.
  • Cover and cook on high for 2-3 hours on high, or low for 4-5.
  • Uncover and add the remaining ½ teaspoon salt, parmesan cheese, herbs, and pepper, tossing to coat.
  • Cover and cook on high for an additional 15 minutes, or until the cheese begins to melt. Serve immediately. Do not hold on warm or overcook, as the potatoes run the risk of turning gummy.

Notes

See blog post, above, for notes and ingredient substitutions.
Slow cooker temperatures can vary, so you may need to adjust cook times up or down depending on your particular model. Begin checking at 2 hours on high, and 4 hours on low, but do not uncover before the first 2 hours.
