What Kind of Potatoes Should I Use?

I find that russet potatoes give the fluffiest texture, while Yukon Golds add a buttery, rich flavor and a creamier consistency. You can use either depending on your texture preference — or even a combination of both for the best of both worlds.

Options for Substitutions

• Butter: Use plant-based butter for a dairy-free version.
• Milk or Cream: Substitute with almond milk, oat milk, or a dairy-free creamer for vegan mashed potatoes.
• Garlic: If you’re not a garlic fan, leave it out or replace with roasted shallots.
• Sour Cream or Cream Cheese: Both add richness; Greek yogurt is a great protein-packed alternative.
• Chives: Swap with parsley, green onions, or skip entirely if you prefer a simpler flavor.

Ingredients for This Crockpot Mashed Potatoes Recipe

• Russet Potatoes or Yukon Golds: These are the heart of the dish. Russets offer a fluffy texture, while Yukon Golds are naturally buttery and creamy.
• Butter: Adds richness and depth of flavor. You can use salted or unsalted, depending on preference.
• Garlic (optional): Fresh garlic cloves add a subtle, aromatic boost without overwhelming the flavor.
• Heavy Cream or Whole Milk: Ensures ultra-creamy mashed potatoes. You can use either depending on how rich you want them.
• Cream Cheese or Sour Cream: These lend a tangy flavor and enhance the creaminess.
• Salt & Pepper: Essential for seasoning and bringing out all the other flavors.
• Chives or Fresh Herbs: Optional garnish for a pop of color and a mild oniony flavor.

Step 1: Prep the Potatoes

Peel the potatoes and cut them into roughly equal chunks, about 1 1/2 to 2 inches thick. This ensures even cooking and makes mashing easier later on.

---

Step 2: Add to Crockpot

Place the potato chunks into the crockpot. Add garlic cloves (if using), a generous pinch of salt, and enough water or broth to cover the potatoes by about half. The steam and moisture will cook them through without needing to be fully submerged.

---

Step 3: Slow Cook

Cover the crockpot with a lid and set it to HIGH for 3-4 hours or LOW for 6-7 hours. The potatoes are ready when they’re fork-tender and break apart easily.

---

Step 4: Drain and Mash

Once cooked, drain any excess liquid if needed. Use a potato masher or hand mixer to start breaking them down directly in the crockpot.

---

Step 5: Mix in the Good Stuff

Add the butter, cream or milk, and cream cheese or sour cream. Season with salt and pepper. Continue mashing until smooth or leave a few lumps for texture.

---

Step 6: Keep Warm and Serve

Switch the crockpot to the “Warm” setting if you’re not serving immediately. Stir in chopped chives or herbs just before serving for a fresh finish.

How Long to Prepare The Best Crockpot Mashed Potatoes

Prep Time: The prep work is minimal. Peeling and chopping the potatoes takes about 10–15 minutes. If you’re using garlic, you’ll need another couple of minutes to peel and add it in. The rest is hands-off.

Cook Time: On HIGH, the potatoes take 3–4 hours to become perfectly tender. If you want to let them simmer slowly while you focus on other tasks, LOW for 6–7 hours works beautifully. Once done, they stay warm in the crockpot until you’re ready to serve.

Tips for Perfect Crockpot Mashed Potatoes

• Cut potatoes evenly so they cook at the same rate and mash easily.
• Don’t overcook — they should be fork-tender, not mushy.
• Use warm milk or cream when mixing in for a smoother texture.
• Mash in the crockpot to keep everything warm and contained.
• Taste as you go — adjust salt, butter, or cream based on your preference.

---

Watch Out for These Mistakes While Cooking

• Adding too much liquid: Only cover potatoes halfway to avoid watery mash.
• Skipping seasoning during cooking: Seasoning the cooking water or broth enhances flavor.
• Not draining excess water before mashing can lead to soggy potatoes.
• Using cold dairy: Cold butter or cream can make the potatoes gummy.
• Over-mixing: This can turn mashed potatoes gluey. Mash just until smooth.
