How to Make Roasted Garlic Mashed Potatoes {Slow Cooker}
Step 1: Prepare Your Slow Cooker
Start by spraying the inside of your three-quart slow cooker with cooking spray. This step helps prevent sticking and makes cleanup a breeze! Next, add in your chopped potatoes, fresh thyme, roasted garlic cloves, butter, salt, pepper, and broth. Give it a gentle stir to combine everything well.
Step 2: Cook Until Tender
Cover your slow cooker and set it on high for about 4-5 hours or low for 7-8 hours. This slow cooking process allows all those flavors to meld beautifully together while making the potatoes incredibly tender.
Step 3: Blend to Perfection
Once cooked, add the heavy cream according to your preference—start with ⅓ cup and adjust if you want them creamier! Using a hand mixer or potato masher, blend until smooth (or leave them a bit rustic if that’s your style). Be careful not to overmix; we don’t want gummy potatoes here!
Step 4: Final Touches
After blending, taste and adjust seasoning with more salt and pepper if needed. Finally, sprinkle some chopped parsley on top and fold it through gently before serving.
And there you have it—deliciously creamy Roasted Garlic Mashed Potatoes made effortlessly in your slow cooker! Enjoy every bite!
Pro Tips for Making Roasted Garlic Mashed Potatoes {Slow Cooker}
These mashed potatoes are sure to impress, and with a few tips, you can make them even better!
-
Choose the right potatoes: Using red potatoes is ideal for this recipe as they have a waxy texture that contributes to creamy mashed potatoes. Their natural sweetness complements the roasted garlic beautifully.
-
Don’t rush the roasting: If you’re making your own roasted garlic, take your time! Roasting until golden caramelizes the sugars and enhances flavor, giving your mashed potatoes that rich, sweet taste.
-
Adjust to texture preference: Start with ⅓ cup of heavy cream and mix. If you prefer a creamier texture, add more until you reach your desired consistency. This allows you to customize based on your taste.
-
Use fresh herbs: Fresh thyme adds an aromatic quality that dried herbs simply can’t match. Feel free to experiment with other herbs like rosemary or chives for different flavors!
-
Season gradually: After mashing, taste and adjust seasoning as needed. This ensures every bite is perfectly flavorful and tailored to your liking.
