How to Make Garlic Herb Mashed Potatoes in a Slow Cooker

Begin by peeling and cutting the Yukon Gold potatoes into evenly-sized chunks, about 1 inch each. This ensures they cook evenly in the slow cooker. Place the potatoes into the slow cooker and add the minced garlic, butter, salt, and pepper.

Cover and cook on high for 3 to 4 hours or on low for 6 to 7 hours. You’ll know they’re done when a fork slides through the potatoes easily. At this point, use a potato masher or hand mixer to mash them directly in the slow cooker.

Next, slowly add the warm milk while continuing to mash until the potatoes are silky smooth. If using, fold in sour cream or cream cheese for extra richness. Finally, stir in chopped parsley, taste, and adjust the seasoning as needed.

Tips for Creamier Garlic Herb Mashed Potatoes

Here are a few tips to ensure your Garlic Herb Mashed Potatoes turn out ultra-creamy and delicious:

• Warm the milk before adding to the potatoes to help them absorb it smoothly.
• Don’t overmix, especially with a hand mixer. Overworked potatoes can become gluey.
• Use Yukon Gold potatoes, as they’re naturally creamy and buttery.
• Fold in sour cream or cream cheese for a richer texture and tangy kick.
• Sauté the garlic in butter before adding for a deeper flavor, if desired.

Serving Suggestions and Presentation Ideas

Garlic Herb Mashed Potatoes pair beautifully with roasted meats, grilled vegetables, and holiday entrees. Serve them as a side dish for chicken, turkey, meatloaf, or vegetarian mains like lentil loaf or roasted mushrooms.

For presentation, spoon the mashed potatoes into a warm serving bowl. Add a pat of butter on top, a sprinkle of fresh parsley, and a light dusting of cracked black pepper.
