- Freshly ground black pepper, to taste: Adds a subtle heat and depth to the dish.
- 1/3 cup sour cream: Introduces a tangy creaminess that lightens the texture beautifully.

How to Make Crockpot Garlic Mashed Potatoes Recipe
Step 1: Prepare the Slow Cooker
Start by spraying the inside of your slow cooker with cooking spray. This small step is crucial as it prevents your potatoes and garlic mixture from sticking to the sides and makes cleaning up a much easier task later on.
Step 2: Combine and Cook the Potatoes
Place the quartered baby potatoes, butter, and minced garlic right into the slow cooker, then pour in the water. Season everything generously with kosher salt and freshly ground black pepper before giving it a good stir. Cover the slow cooker and set it to cook on high for about 3 hours. You’ll want to check for fork-tender potatoes before moving on.
Step 3: Mash and Flavor
When your potatoes are perfectly tender, add the sour cream, milk, oregano, and rosemary directly into the crockpot. Use a potato masher to blend everything into a creamy, dreamy texture. Taste and adjust the seasoning if needed — a well-seasoned mashed potato can truly make a difference.
Step 4: Garnish and Serve
Sprinkle the chopped chives over the top for a pop of color and a lovely, fresh onion flavor. These little finishing touches bring your Crockpot Garlic Mashed Potatoes Recipe beautifully to life and make every bite inviting.

Creative Ways to Present
For a cozy dinner, serve the mashed potatoes in a warmed ceramic bowl with a pat of butter melting on top. Alternatively, you could pipe the creamy mixture into pretty mounds using a piping bag and bake under the broiler briefly to create golden, crispy edges — a stunning twist on classic mashed potatoes.

Storing Leftovers

FAQs
Can I use regular potatoes instead of baby potatoes for this Crockpot Garlic Mashed Potatoes Recipe?
Absolutely! While baby potatoes work wonderfully because they cook evenly and mash well, you can substitute Yukon Gold or Russet potatoes. Just cut them into uniform pieces to ensure even cooking in the crockpot.
How can I make the mashed potatoes creamier?
For extra creaminess, increase the amount of sour cream or butter slightly. You can also add a splash of heavy cream instead of milk. Be sure to mash thoroughly for a smooth and luscious texture.
Is it possible to make this recipe dairy-free?
Yes, you can swap out butter, sour cream, and milk for plant-based alternatives like olive oil or vegan butter, dairy-free sour cream, and almond or oat milk. The flavors will be slightly different but still delicious.
What if I don’t have oregano or rosemary? Can I use other herbs?
Definitely! Thyme, parsley, or even a pinch of sage can be great substitutes. Fresh herbs can also be used—just add them toward the end to keep their bright flavor.
Can I double this Crockpot Garlic Mashed Potatoes Recipe?
You can double it if your slow cooker can accommodate the increased quantity. Just be mindful that cooking times may need to be extended to ensure the potatoes become tender all the way through.
