The Complete Slow Cooker Onion Butter Potatoes Recipe<\/h2>\n\n\n\n

This recipe serves 6\u20118 people. It fits a 5\u20116 quart slow cooker and can easily be doubled.<\/p>\n\n\n\n

Ingredients:<\/h3>\n\n\n\n
    \n
  • 3 lbs (about 1.4 kg) baby potatoes or Yukon Gold potatoes<\/strong> \u2013 halved or quartered into 1\u2011inch pieces<\/li>\n\n\n\n
  • 1 large yellow onion<\/strong>, thinly sliced<\/li>\n\n\n\n
  • \u00bd cup (113g, 1 stick) unsalted butter<\/strong>, cut into small cubes<\/li>\n\n\n\n
  • 4 cloves garlic<\/strong>, minced (optional but recommended)<\/li>\n\n\n\n
  • 1 teaspoon salt<\/strong> (or to taste)<\/li>\n\n\n\n
  • \u00bd teaspoon black pepper<\/strong><\/li>\n\n\n\n
  • 1 teaspoon dried thyme<\/strong> or rosemary (or 1 tablespoon fresh)<\/li>\n\n\n\n
  • \u00bd cup (120ml) chicken or vegetable broth<\/strong> (or water)<\/li>\n\n\n\n
  • Optional: \u00bc cup fresh parsley, chopped for garnish<\/strong><\/li>\n\n\n\n
  • Optional: \u00bd cup grated Parmesan cheese<\/strong> (add at the end)<\/li>\n<\/ul>\n\n\n\n

    Equipment:<\/h3>\n\n\n\n
      \n
    • 5\u20116 quart slow cooker<\/li>\n\n\n\n
    • Knife and cutting board<\/li>\n\n\n\n
    • Measuring cups and spoons<\/li>\n\n\n\n
    • Spatula or large spoon<\/li>\n<\/ul>\n\n\n\n

      Step\u2011by\u2011Step Instructions<\/h2>\n\n\n\n

      Step 1 \u2013 Prepare the Potatoes and Onions<\/h3>\n\n\n\n

      Wash the potatoes thoroughly. If using baby potatoes, leave them whole or cut them in half. If using Yukon Gold potatoes, cut them into 1\u2011inch chunks. Thickly slice the onion into half\u2011rings or thin wedges. Mince the garlic if using.<\/p>\n\n\n\n

      Step 2 \u2013 Layer in the Slow Cooker<\/h3>\n\n\n\n

      Place the potatoes and sliced onions in the slow cooker. Sprinkle with salt, pepper, and dried thyme (or rosemary). Dot the butter cubes evenly over the top. Add the minced garlic and pour in the broth (or water). Do not stir \u2013 the butter will melt and distribute as it cooks.<\/p>\n\n\n\n

      Step 3 \u2013 Slow Cook<\/h3>\n\n\n\n

      Cover and cook on LOW for 4\u20115 hours or on HIGH for 2\u20113 hours. The potatoes are done when they are fork\u2011tender and easily pierced with a knife. Stir gently once halfway through cooking if possible, but it is not necessary. The butter and onion juices will create a rich, savory sauce.<\/p>\n\n\n\n

      Step 4 \u2013 Optional: Thicken the Sauce<\/h3>\n\n\n\n

      If you prefer a thicker sauce, remove the potatoes with a slotted spoon and set aside. Whisk a slurry of 1 tablespoon cornstarch mixed with 2 tablespoons of cold water into the liquid in the slow cooker. Cook on HIGH for 10\u201115 minutes until thickened. Return the potatoes to the pot and stir to coat.<\/p>\n\n\n\n

      Step 5 \u2013 Garnish and Serve<\/h3>\n\n\n\n

      Taste and adjust seasoning. Garnish with fresh parsley and, if desired, sprinkle with grated Parmesan cheese. Serve hot directly from the slow cooker or transfer to a serving bowl. These buttery slow cooker potatoes<\/strong> are delicious alongside roasted meats, poultry, or as a vegetarian main.<\/p>\n\n\n\n

      Pro Tips for the Best Slow Cooker Onion Butter Potatoes<\/h2>\n\n\n\n

      Follow these expert tips for perfect crockpot buttered potatoes<\/strong> every time:<\/p>\n\n\n\n

      Use waxy potatoes for best texture<\/strong> \u2013 Baby potatoes, Yukon Golds, or red potatoes hold their shape well during long cooking. Russets can become mushy.<\/p>\n\n\n\n

      Cut potatoes into uniform pieces<\/strong> \u2013 Even sizes ensure even cooking. Aim for 1\u2011inch chunks.<\/p>\n\n\n\n

      Do not skimp on the butter<\/strong> \u2013 The butter is the star. Use good quality unsalted butter so you can control the salt level.<\/p>\n\n\n\n

      Add broth or water<\/strong> \u2013 A small amount of liquid prevents sticking and helps the potatoes cook evenly. The potatoes release their own moisture, but a little extra helps.<\/p>\n\n\n\n

      Use fresh herbs for a brighter flavor<\/strong> \u2013 Dried herbs work, but fresh rosemary, thyme, or parsley at the end elevate the dish.<\/p>\n\n\n\n

      Make it a complete meal<\/strong> \u2013 Add kielbasa or smoked sausage during the last hour of cooking for a one\u2011pot dinner.<\/p>\n\n\n\n

      Do not overcook<\/strong> \u2013 Check for doneness at the lower end of the time range. Overcooked potatoes become mushy and waterlogged.<\/p>\n\n\n\n

      Delicious Variations (Same Slow Cooker Method)<\/h2>\n\n\n\n

      Once you master the classic onion butter potatoes, try these fun twists. These slow cooker potato variations<\/strong> will keep your side dish game strong.<\/p>\n\n\n\n

      1. Garlic Herb Onion Butter Potatoes<\/h3>\n\n\n\n

      Add 1 tablespoon of fresh rosemary and 1 tablespoon of fresh thyme along with the garlic. The herbaceous aroma is incredible. Use 6 cloves of garlic for a more intense garlic flavor.<\/p>\n\n\n\n

      2. Cheesy Onion Butter Potatoes<\/h3>\n\n\n\n

      During the last 30 minutes of cooking, sprinkle 1 cup of shredded cheddar, Gruy\u00e8re, or Parmesan cheese over the potatoes. Cover and let melt. The cheese creates a golden, gooey crust. This is a cheesy crockpot potato side dish<\/strong> that is pure comfort.<\/p>\n\n\n\n

      3. Bacon Onion Butter Potatoes<\/h3>\n\n\n\n

      Cook 6 slices of bacon until crispy, then crumble. Sprinkle over the potatoes just before serving. The smoky, salty bacon is a perfect match for the buttery onions. You can also add \u00bc cup of real bacon bits to the slow cooker during the last 30 minutes.<\/p>\n\n\n\n

      Add \u00bd teaspoon of red pepper flakes or a diced jalape\u00f1o (seeds removed) along with the onions. The subtle heat balances the richness of the butter.<\/p>\n\n\n\n

      5. Lemon Dill Onion Butter Potatoes<\/h3>\n\n\n\n

      Add 2 tablespoons of fresh dill and the zest of 1 lemon during the last 10 minutes of cooking. The bright, fresh flavors are perfect for spring and summer.<\/p>\n\n\n\n

      Add 8 oz of sliced cremini mushrooms along with the onions. The mushrooms release their earthy flavor and become tender. This turns the dish into a hearty vegetarian main.<\/p>\n\n\n\n

      7. Low\u2011Carb \/ Keto Onion Butter Potatoes<\/h3>\n\n\n\n

      Potatoes are naturally higher in carbs, but you can serve smaller portions alongside protein. For a lower\u2011carb option, replace half the potatoes with cauliflower florets. The cauliflower will absorb the butter and onion flavors beautifully.<\/p>\n\n\n\n

      Replace half or all of the white potatoes with sweet potatoes. The natural sweetness of the sweet potatoes pairs wonderfully with the caramelized onions and butter. Reduce added salt slightly.<\/p>\n\n\n\n

      What to Serve with Slow Cooker Onion Butter Potatoes<\/h2>\n\n\n\n

      These potatoes are incredibly versatile. Serve them with:<\/p>\n\n\n\n

      Roast chicken, turkey, or beef<\/strong> \u2013 Classic comfort pairing.<\/p>\n\n\n\n

      Grilled steak or pork chops<\/strong> \u2013 The creamy potatoes balance the smoky meat.<\/p>\n\n\n\n

      Baked ham or meatloaf<\/strong> \u2013 A hearty, satisfying meal.<\/p>\n\n\n\n

      Roasted vegetables and a green salad<\/strong> \u2013 For a vegetarian feast.<\/p>\n\n\n\n

      Fried eggs and bacon<\/strong> \u2013 For a decadent breakfast or brunch.<\/p>\n\n\n\n

      As a standalone side<\/strong> \u2013 They are that good.<\/p>\n\n\n\n

      How to Store, Reheat, and Make Ahead<\/h2>\n\n\n\n

      Refrigerator<\/h3>\n\n\n\n

      Store leftovers in an airtight container for up to 4 days. The potatoes will firm up as they cool; reheat gently.<\/p>\n\n\n\n

      Freezer<\/h3>\n\n\n\n

      These potatoes can be frozen for up to 2 months. Cool completely, then transfer to a freezer\u2011safe container. Thaw overnight in the refrigerator. Reheat in a skillet or microwave. Note that the texture may become slightly softer.<\/p>\n\n\n\n

      Reheating Best Practices<\/h3>\n\n\n\n

      Stovetop:<\/strong> Reheat in a skillet over medium heat with a splash of broth or water. Microwave:<\/strong> Heat in 60\u2011second bursts, stirring between. Slow cooker:<\/strong> Reheat on LOW for 1\u20112 hours.<\/p>\n\n\n\n

      Make Ahead for a Party<\/h3>\n\n\n\n

      Cook the potatoes as directed, then transfer to a slow cooker on the \u201cwarm\u201d setting. They will stay perfect for hours. You can also prepare the ingredients the night before (chop potatoes, slice onions) and store in the refrigerator. In the morning, dump everything into the slow cooker and cook.<\/p>\n\n\n\n

      Frequently Asked Questions<\/h2>\n\n\n\n

      Can I use frozen potatoes?<\/h3>\n\n\n\n

      Yes. Use frozen diced or baby potatoes. Do not thaw them before adding to the slow cooker. Reduce the broth to \u00bc cup, as frozen potatoes release more water. Cooking time may be slightly shorter.<\/p>\n\n\n\n

      Can I use margarine instead of butter?<\/h3>\n\n\n\n

      Butter is strongly recommended for flavor. Margarine has a higher water content and may result in a less rich, less flavorful dish. If you must substitute, use a high\u2011quality plant\u2011based butter.<\/p>\n\n\n\n

      Why are my potatoes mushy?<\/h3>\n\n\n\n

      Mushy potatoes occur when they are overcooked or when using starchy potatoes like Russets. Use waxy potatoes (baby, Yukon Gold, red) and check for doneness at the lower end of the cooking time.<\/p>\n\n\n\n

      Can I add other vegetables?<\/h3>\n\n\n\n

      Absolutely. Carrots, parsnips, and celery can be added along with the potatoes. Add them in similar\u2011sized chunks. Mushrooms, bell peppers, or zucchini should be added during the last hour to prevent mushiness.<\/p>\n\n\n\n

      How many calories are in a serving?<\/h3>\n\n\n\n

      One serving (about 1 cup) contains approximately 280\u2011350 calories, 16g fat, 32g carbohydrates, and 5g protein. This is a rich, satisfying side dish<\/strong> \u2013 perfect for special occasions.<\/p>\n\n\n\n

      Can I make this dairy\u2011free?<\/h3>\n\n\n\n

      Yes. Use a high\u2011quality plant\u2011based butter (like Miyoko\u2019s or Earth Balance) and omit the cheese. Use vegetable broth. The dish will still be delicious.<\/p>\n\n\n\n

      Can I cook these on HIGH for less time?<\/h3>\n\n\n\n

      Yes. Cook on HIGH for 2\u20113 hours. Check for doneness at 2 hours. HIGH heat can sometimes cause potatoes to become unevenly cooked, so LOW is preferred for the creamiest texture.<\/p>\n\n\n\n

      The Magic of Slow Cooker Side Dishes<\/h2>\n\n\n\n

      Slow cookers are often reserved for soups and stews, but they shine for side dishes as well. Cooking potatoes in a slow cooker allows them to gently steam and braise in butter and onion juices, resulting in a texture that is creamier than boiled potatoes and more flavorful than roasted ones. The low, consistent heat ensures that the potatoes cook evenly without burning or sticking. Plus, the slow cooker frees up oven and stovetop space \u2013 a lifesaver during holiday meal prep. This crockpot potato recipe<\/strong> is a perfect example of why your slow cooker should be used for so much more than chili.<\/p>\n\n\n\n
