Why you’ll love it

Mashed potatoes are a must-have side dish, especially during Thanksgiving, Christmas, and big family gatherings. But let’s be honest — stovetop mashed potatoes can take up precious burner space, and timing them perfectly with everything else can feel stressful.

That’s exactly why I love making these in the crockpot.

The potatoes cook slowly in broth and garlic until perfectly tender, then get mashed right in the slow cooker with butter and cream. They stay warm for hours without drying out, making them ideal for entertaining. The texture is velvety smooth, rich, and loaded with real garlic flavor.

Using Yukon Gold potatoes makes all the difference. They naturally have a buttery texture and creamy consistency, so you don’t even need to add a ton of extras to make them taste luxurious.

The best part? You can make them ahead of time and simply keep them on the “warm” setting until serving. Less stress. Fewer dishes. More time to actually enjoy your meal.

What you’ll need

Yukon Gold potatoes – My go-to for mashed potatoes. They’re naturally creamy and hold their texture beautifully without becoming gluey.

Chicken or vegetable broth – Adds flavor while the potatoes cook instead of boiling them in plain water.

Salt – Essential for seasoning the potatoes properly from the start.

Heavy cream – Makes the mashed potatoes rich, silky, and smooth.

Butter – Adds that classic buttery flavor and glossy finish.

Garlic – Fresh minced garlic gives these potatoes a subtle but delicious savory depth.

Pro tips

Can I leave the skins on?
Yes! Yukon Gold skins are thin and tender. Leaving them on adds texture and nutrients.

How do I avoid gluey mashed potatoes?
Don’t overmix, especially if using a hand mixer. Overworking releases too much starch.

What if they’re too thick?
Add a splash of warm cream or broth and stir gently until you reach your desired consistency.

Can I double the recipe?
Absolutely. Just make sure your slow cooker is large enough to accommodate everything comfortably.

Substitutions and variations

Make it extra garlicky – Roast the garlic beforehand for deeper flavor.

Add cream cheese – Stir in 4 ounces of softened cream cheese for ultra-rich mashed potatoes.

Use half-and-half – You can substitute half-and-half for heavy cream, but the texture won’t be quite as rich.

Make it vegetarian – Simply use vegetable broth instead of chicken broth.

Add herbs – Fresh chopped chives, thyme, or rosemary elevate the flavor beautifully.

What to serve with these mashed potatoes

These mashed potatoes pair perfectly with holiday classics like:

Roast turkey
Honey glazed ham
Roast chicken
Meatloaf

They’re also amazing topped with gravy, served alongside green beans, roasted carrots, or a fresh salad.

Since they stay warm in the crockpot, they’re ideal for buffet-style meals and large gatherings.

Leftovers and storage

Leftovers will keep in an airtight container in the refrigerator for 3–4 days.

To reheat, warm gently on the stovetop or microwave. Add a splash of cream or milk if needed to loosen them up.

Freezing mashed potatoes is possible, but the texture may change slightly. If freezing, store in a freezer-safe container for up to 2 months and thaw overnight in the refrigerator before reheating.
