Why You’ll Love This Recipe

It’s a Thanksgiving lifesaver. The slow cooker frees up precious stovetop real estate, and there's no need to babysit a boiling pot of water.

Everything happens in one pot just toss in your ingredients, let the crockpot work its magic, and mash it all up at the end. So simple. So good.

What Makes These Potatoes Special

• Garlicky Goodness: Minced garlic cooks with the potatoes, mellowing into a rich, warm flavor that doesn’t overpower.
• Creamy Texture: Sour cream and milk add fluffiness, while the skins give a rustic edge.
• Perfect for Crowds: Makes enough for 8 — ideal for Thanksgiving dinner or a hearty Sunday roast.

Ingredients You’ll Need

• Cooking spray
• 3 lbs. baby potatoes (quartered, red or gold)
• 4 tablespoons unsalted butter
• 3 cloves garlic, minced
• ¼ cup water
• Kosher salt and freshly ground black pepper
• ⅓ cup sour cream
• ¼ cup milk
• 1 teaspoon dried oregano
• ½ teaspoon dried rosemary
• 1 tablespoon chopped chives (for garnish)

Ingredient Notes & Swaps

Potatoes: Baby potatoes cook quickly and mash beautifully. You can substitute Yukon Gold or peeled Russets if needed.

Sour Cream: Adds tang and creaminess — Greek yogurt works too if you’re in a pinch.

Milk: Whole milk is ideal for richness, but 2% or even unsweetened plant milk will do the job.

Garlic Lovers Tip: Want it even bolder? Add a roasted garlic clove or two when mashing.

How to Make Crockpot Garlic Mashed Potatoes

1. Prep the slow cooker by spraying it with cooking spray.
2. Add potatoes, butter, garlic, and water. Season well with salt and pepper and stir to combine.

3. Cover and cook on high for 3 hours, or until potatoes are tender. Test by piercing with a fork or knife.
4. Once soft, add sour cream, milk, oregano, and rosemary.
5. Mash everything right in the pot using a handheld masher or immersion blender, depending on how smooth you like it.

6. Taste and adjust seasoning as needed.
7. Top with chopped chives, and serve warm directly from the slow cooker.

Tips for the Best Slow Cooker Mashed Potatoes

Cut potatoes evenly so they cook at the same rate.

Don’t overwater — the small amount of water steams the potatoes without drowning them.

Warm your milk before adding it to keep everything hot and mix smoothly.

Keep the lid on while mashing to retain heat if serving later.
