Ingredients for Make Ahead Crockpot Mashed Potatoes
Here’s what you’ll need to make these heavenly potatoes – and trust me, every single one of these ingredients plays a crucial role:
- 5 lbs russet potatoes – peeled and cubed (don’t skimp on peeling – you want that smooth texture!)
- 1 cup milk – whole milk makes them extra creamy, but 2% works in a pinch
- 1/2 cup unsalted butter – softened (I leave mine out overnight – cold butter won’t melt right)
- 1 tsp salt – plus more to taste at the end
- 1/2 tsp black pepper – freshly ground if you’ve got it
- 1/2 cup sour cream – the secret to that rich, tangy flavor
- 1/4 cup chicken or vegetable broth – for that extra depth of flavor (I use the good stuff from my freezer)
See? Nothing fancy – just real ingredients that work together to create potato magic!
Equipment For This Recipe
These tools make preparing crockpot mashed potatoes quick and easy!
Equipment You’ll Need
You probably already have most of these in your kitchen – I know I did before I discovered this recipe! Here’s what you’ll need:
- A trusty crockpot – any size that fits 5 lbs of potatoes (mine’s a basic 6-quart)
- Potato peeler – or a sharp paring knife if you’re feeling old-school
- Measuring cups – eyeballing the butter never works out for me!
- Potato masher or electric mixer – masher for rustic texture, mixer for super smooth
- Wooden spoon – for that final stir before serving
That’s it! No fancy gadgets required – just simple tools for simple (but amazing) potatoes.
How to Make Make Ahead Crockpot Mashed Potatoes
Okay, let’s get to the good stuff! Making these potatoes is so easy you’ll laugh – but there are a few tricks I’ve learned over the years to make them absolutely perfect every time. Follow these steps and you’ll be the mashed potato hero at your next gathering!
Step 1: Prep the Potatoes
First things first – peel those potatoes! I know some folks like skins left on, but trust me, peeling gives you that velvety smooth texture we’re after. Cut them into 1-inch cubes – uniform size means they’ll all cook evenly. Don’t worry about being perfect, just get them roughly the same size.
Step 2: Slow Cook to Perfection
Now the magic happens! Dump your potato cubes into the crockpot first. Then add the milk, butter, salt and pepper right on top. Here’s my secret – don’t stir yet! Just cover and set it on low for 4-5 hours. The potatoes will steam in the milk and butter, absorbing all that goodness. Resist the urge to peek – we want all that heat staying inside!
Step 3: Mash and Adjust
When your kitchen smells amazing and the potatoes are fork-tender, it’s time to mash! I use my hand mixer for super creamy potatoes, but a masher works great if you like them chunkier. Now stir in the sour cream and broth – the broth helps loosen them up if they’re too thick. Taste and add more salt if needed – potatoes can handle more than you think! Keep them warm in the crockpot until serving – they’ll just get better as they sit.

Tips for the Best Make Ahead Crockpot Mashed Potatoes
Over the years, I’ve picked up some tricks that take these potatoes from good to “can I get your recipe?” amazing:
- Warm your milk and butter – Cold ingredients slow down cooking and can make the texture grainy. I microwave mine for 30 seconds before adding.
- Reserve some broth – Start with just half the broth when mashing, then add more as needed. Potatoes can vary in starch content!
- Season in layers – Add salt when cooking, then taste again after mashing – they’ll need more than you think!
- Don’t overmix – Stop when they’re smooth or you’ll end up with gummy potatoes. Ask me how I know!
- Keep them covered – If holding in the crockpot, keep the lid on tight to prevent a skin from forming.
These little things make such a difference – your guests will swear you spent hours on them!
Variations for Make Ahead Crockpot Mashed Potatoes
Listen, as much as I adore the classic version, sometimes I get wild and mix things up! Here are my favorite ways to play with this recipe:
- Garlic lovers – Toss in 4-5 minced garlic cloves with the potatoes. The slow cooking mellows the sharpness beautifully.
- Cheese please – Stir in 1 cup shredded cheddar or parmesan at the end – it gets all melty and amazing.
- Herb garden special – Fresh chives, rosemary or thyme take these to fancy restaurant level.
- Yukon gold swap – These buttery potatoes make an extra rich version (no need to peel if you don’t want to!).
- Cream cheese twist – Replace half the sour cream with softened cream cheese for ultra-luxurious potatoes.
The beauty is – once you’ve got the basic method down, the possibilities are endless. Go wild and make them your own!
Serving and Storing Make Ahead Crockpot Mashed Potatoes
Here’s the best part – these potatoes actually improve with time! If you’re serving them right away, give them a quick stir and transfer to a pretty serving bowl. I love topping mine with a pat of butter melting in the center and a sprinkle of fresh chives or parsley. Leftovers? Just pop them in an airtight container – they’ll keep beautifully in the fridge for up to 3 days.
When reheating, I either warm them gently on the stovetop with a splash of milk (stir constantly!) or back in the crockpot on low for about an hour. Pro tip: if they seem dry after storage, stir in a tablespoon of broth or milk to bring back that creamy texture. These potatoes freeze surprisingly well too – just thaw overnight in the fridge before reheating!
Nutritional Information
Now, I’m no nutritionist, but I can tell you these creamy potatoes are made with real, wholesome ingredients. Keep in mind that nutritional values will change depending on the exact brands and amounts you use – especially with those delicious butter and sour cream additions! If you’re watching specific dietary needs, you might adjust the milk or butter amounts, but honestly? Some things are just worth savoring as-is.
Frequently Asked Questions
I get asked about these crockpot mashed potatoes all the time – here are the questions that come up most often in my kitchen (and at every potluck I bring these to!):
Can I leave the skins on the potatoes?
You absolutely can if you prefer a more rustic texture! Just give them a good scrub first. I personally peel mine because I love that ultra-smooth, velvety consistency, but skins add nice texture and nutrients.
How do I prevent gluey mashed potatoes?
Oh honey, we’ve all been there! The key is not to overmix – stop as soon as they’re smooth. Also, using russet potatoes (they’re starchier) and warming your dairy ingredients first helps avoid that pasty texture.
Can I freeze the leftovers?
Yes! They freeze surprisingly well for up to 2 months. Thaw overnight in the fridge, then reheat slowly with a splash of milk or broth to bring back the creaminess.
Why use broth instead of all milk?
The broth adds such a wonderful savory depth that plain milk can’t match! It balances the richness perfectly. But if you’re out, extra milk works fine in a pinch.
