Ingredients

To make these delicious Roasted Garlic Mashed Potatoes in the slow cooker, you’ll need the following ingredients:

1 teaspoon fresh thyme
1 head roasted garlic (12-15 cloves) (see notes)

⅓-½ cup heavy cream (to preference)
1 tablespoon chopped parsley

How to Make Roasted Garlic Mashed Potatoes {Slow Cooker}

Step 1: Prepare Your Slow Cooker

Spray the inside of a three-quart slow cooker with cooking spray. This keeps the mashed potatoes from sticking and ensures easy cleanup.

Add the following ingredients into the slow cooker:
1. Red potatoes
2. Fresh thyme

5. Salt
6. Black pepper

Cover and allow the slow cooker to cook for 4-5 hours on high or 7-8 hours on low.

Step 3: Add Creaminess

Once the cooking time is up, add heavy cream according to your preference:
1. Start with ⅓ cup; if you desire a creamier texture, add up to a full ½ cup.
2. Remember, you can substitute heavy cream with regular milk, but keep in mind it won’t yield as rich a flavor.

Step 4: Mash and Serve

Use a hand mixer on low speed or a potato masher for more rustic mashed potatoes:
1. Be cautious while mixing; don’t let the blades get too close to the base of the crockpot.
2. Season with additional salt and pepper if needed.

Common Mistakes to Avoid

When making roasted garlic mashed potatoes in a slow cooker, it’s easy to make a few common mistakes. Here are some tips to ensure your dish turns out perfectly.

Using the wrong type of potatoes: Starchy potatoes like russets or red potatoes work best for creamy mashed potatoes. Avoid waxy varieties which won’t yield the same texture.
Not seasoning enough: It’s crucial to add salt and pepper early in the cooking process. This allows the flavors to develop. Always taste before serving and adjust as needed.
Overcooking the potatoes: Monitor the cooking time closely. Overcooked potatoes can become watery and gummy. Stick to 4-5 hours on high or 7-8 hours on low.
Skipping the roasted garlic: The essence of this recipe is the roasted garlic flavor. Don’t skip this step; it adds depth and richness that plain mashed potatoes lack.
Adding too much cream at once: Start with less heavy cream and add more if needed. This prevents your mashed potatoes from becoming overly liquidy.

Refrigerator Storage

Store in an airtight container for up to 3 days.
Allow the mashed potatoes to cool before sealing to avoid condensation.
