As a busy home cook who loves to entertain, we know the struggle of juggling stovetop space during big dinners. That's why we've perfected this no boil method. It saves your sanity during the holidays (hello, Thanksgiving!) and delivers foolproof, flavorful mashed potatoes every single time.

The Secret to good Fork-Tender Creaminess

We've personally tested countless methods live our stove top creamy mashed potatoesand the slow cooker reigns supreme for two reasons. The flavor and texture. The potatoes slowly simmer in the broth and garlic, absorbing all that gorgeous flavor and moisture until they are perfectly fork tender. This consistent, gentle heat is the secret to achieving the ultimate, velvety creaminess without overworking the starch. You don't even need heavy cream as the flavors intensify in the slow cooker.

Benefits of This Slow Cooker Method

Why make mashed potatoes in a crockpot? Honestly, once you try it, you might never go back to boiling water again.

• Frees Up Stove Space. This is an absolute game changer for big holiday meals like ThanksgivingEaster or Christmas. It leaves your burners free for gravy stuffingand other sides.
• Set It and Forget It. Beyond the initial chopping, the slow cooker does all the heavy lifting. It's a low stress, set and forget recipe.
• Keeps Them Perfectly Warm. The warm setting on your crockpot acts like a warming drawer, holding the mash at the good serving temperature for hours without drying them out. This is honestly our favorit as sometimes our family and guests run late and we are left stressing everything will be cold.
• Deep Flavor Infusion. Because the potatoes cook in broth and garlic rather than plain water, they absorb good flavor from the inside out.

The ingredients list

• Chicken Broth – we recommend using chicken broth over stock because it has a lighter, cleaner flavor that enhances the potatoes without overpowering them. Stock is made from bones and tends to be richer and darker, which can make your mash taste too meaty and potentially turn it a muddy color. Broth provides just the right amount of savory seasoning to infuse the potatoes from the inside out while keeping them bright, buttery, and perfectly golden.
• Sour Cream: You can use light sour cream, but full fat yields a reliable results.
• Hot Milk: the key word here is HOT. Never add cold milk to hot mashed potatoes. It cools them down too fast and can make the texture gluey. Heating the milk ensures the potatoes stay fluffy and absorb the dairy instantly.
• Potatoes – This needs its own section as we will explain which ones will work best.

Best Potatoes For Mash

Did you know there are over 4,000 different types of potatoes? Not all potatoes are created equal when it comes to mashing! Below are our recommendations.

• Yukon Gold (Gold Delight): These are our top choice. They have a naturally buttery flavor and a creamy, dense texture that makes for the smoothest mash. Plus, their skin is thin enough that you can leave it on for a rustic texture if you prefer.
• Russet (Sebago): These are high starch potatoes that make for a fluffier, lighter mash. However, they can absorb a lot of water and fall apart easily. If you use these, make sure to peel them completely as the skins are tough.
• Red Potatoes: These are waxy and harder to mash smooth. They can turn gluey if overworked, so we generally recommend sticking to Yukons or Russets for this specific method.

Swaps

This recipe is good as written, but it's also a good canvas for your favorite flavors.

• Roasted Garlic. Swap the fresh garlic for a whole head of Roasted Garlic for a deeper, caramelized flavor.
• Cheesy Mash. Stir in shredded Cheddar, Gruyère, or Gouda along with the Parmesan for an ultra decadent side. Just like our roasted cheesy potatoes recipe.
• Loaded Potatoes. Top with crispy bacon bits, chopped chives, and extra sour cream right before serving just like our cheesy smashed potatoes.
• Herbs: Fresh parsley, thyme, or rosemary added during the last hour of cooking adds a lovely freshness.

On the stove

1. Prep and Cut Uniformly Peel your potatoes (if using Russets) or scrub them clean (if using Yukon Golds and you like a rustic mash). Cut them into uniform chunks, about 1 ½ to 2 inches wide. Uniform cutting ensures every piece cooks at the exact same rate. If you have small and large chunks mixed, the small ones will turn to mush while the large ones remain hard.

1. Layer the Slow Cooker Grease your slow cooker insert lightly with butter or non stick spray (optional, but helps with cleanup). Place all your potato chunks into the bowl.Do not overfill your slow cooker. It should be no more than 2/3 full to allow the heat to circulate evenly.

1. Add Liquid and Aromatics Pour in the chicken broth and add the butter, salt and minced garlic directly on top of the potatoes. Unlike boiling in water where flavor is poured down the sink, cooking in broth infuses the potatoes with savory depth from the inside out. The butter melts down to coat every piece as they soften.

1. Cover and cook on HIGH for 3-4 hours or LOW for 6-7 hours. You'll know they are getting close when the kitchen fills with a rich, buttery garlic aroma. Before you even think about mashing, test a few potato chunks from the center of the pot. A fork should slide through them with zero resistance. If there is even a slight “crunch” or resistance, cover and cook for another 30 minutes. Mashing undercooked potatoes creates lumps that you can't fix later.

1. Do Not Drain! This is the part that scares people, but trust us. Do not drain the liquid. By the time the potatoes are cooked, most of the liquid will have been absorbed or reduced.The remaining liquid is gold. It's packed with starch and flavor. It will incorporate perfectly into the mash, helping to create that velvety texture without needing excessive heavy cream.

1. Add your sour cream and milk to the pot. Use a handheld potato masher or a ricer to mash the potatoes right in the slow cooker. Do not use a food processor or high speed electric mixer. This breaks down the starch cells too aggressively and is the No.1 cause of gluey or gummy potatoes. Mash by hand until just combined.

1. Sprinkle parmesan cheese on top and mix. Taste your potatoes. This is vital because different broths have different salt levels. Add extra salt and cracked black pepper to taste. If they feel too thick, splash in a little warm milk.

1. Serve in a dish, garnish with fresh chives or parsley and serve warm.

Kitchen tip

We have tested this recipe dozens of times to get it right. Here are our secrets to avoiding gluey potatoes.

• Ensure Potatoes are Fork Tender. Before you start mashing, make sure a fork can slide into a potato chunk with zero resistance. If they are even slightly undercooked, you will end up with lumps.
• Don't Over Mix. This is the golden rule! Mash until just combined. Over working potatoes (especially with an electric mixer or food processor) releases too much starch and turns them into a gummy paste. A hand masher or ricer is your best friend here.
• Use Warm Ingredients. If you are adding extra milk or cream at the end, warm it up first. Cold ingredients shock the hot potatoes and make them harder to mix smooth.

The FAQ's

Yes! You can prepare them fully and then keep them on the 'warm' setting for up to 2-4 hours. It's good for timing a dinner party.

Store leftovers in an airtight container in the refrigerator for up to 5 days. To reheat, pop them in the microwave or warm them gently on the stovetop. You may need to add a splash of warm milk or cream to loosen them up and restore that creamy texture.

Food safety guidelines recommend not leaving mashed potatoes out for more than 2 hours. If you need them to sit out longer, keep them in the slow cooker on the warm setting.

Absolutely, provided you have a slow cooker that is large enough (6-quart or larger). Just ensure the crockpot is not more than two thirds full to allow for even cooking. You might need to add 30-60 minutes to the cooking time.
