What makes these Easy Make Ahead Crockpot Mashed Potatoes so wonderful
These mashed potatoes stand out because they’re low-effort and high-reward. By cooking the potatoes gently in the crockpot, you get consistently tender pieces without watching the clock. They’re make-ahead friendly — you can cook them earlier in the day, keep them on warm, and give them a quick mash right before serving. The slow cooker also helps lock in moisture, so the mash stays silky instead of drying out.
Grocery list: Ingredients for Easy Make Ahead Crockpot Mashed Potatoes
- 3 pounds russet potatoes — Starchy potatoes that break down into a fluffy mash.
- 1/2 cup unsalted butter — Adds richness and a smooth finish; use salted butter and reduce added salt if you prefer.
- 1 cup whole milk — Warmed and added gradually for a creamy texture; swap for half-and-half for extra indulgence.
- 1/2 cup sour cream — Optional, for tang and richer mouthfeel.
- 4 cloves garlic — Adds gentle savory depth when cooked with the potatoes; roast first for milder flavor.
- 1 cup low-sodium chicken broth — Keeps the potatoes moist while they cook and adds subtle savory notes.
- 1 teaspoon salt — Essential for flavor; add more to taste after mashing.
- 1/2 teaspoon black pepper — Freshly ground gives the best flavor balance.
- 2 tablespoons chopped chives — A fresh garnish that brightens the dish.
- 4 ounces cream cheese — Optional, stirred in for extra silkiness and tang (especially nice for holiday blends).
Step-by-step: How to make Easy Make Ahead Crockpot Mashed Potatoes
- Peel and cube the potatoes. Aim for 1–1½ inch cubes so everything cooks evenly. Smaller cubes cook a bit faster but don’t overdo it — you want substantial pieces that mash smoothly.
- Layer ingredients in the crockpot. Put the potatoes into the crockpot insert. Add garlic (minced or smashed works), the cup of chicken broth, and about half the salt. Give it a gentle toss so flavors start to mingle.
- Cook low and slow. Cover and cook on HIGH for 2–3 hours or LOW for 4–5 hours, until the potatoes are easily pierced with a fork. Every slow cooker runs a bit differently; test a few pieces to confirm tenderness.
- Drain excess liquid. Once cooked, tilt out any extra liquid you don’t want in the final mash (reserve a little if you like looser potatoes). Return the potatoes to the crockpot set to warm.
- Warm the dairy. Heat the milk and butter together until the butter melts and the mixture is hot. Soften cream cheese into the mix if you’re using it — this helps it blend without lumps.
- Mash and mix. Use a potato masher or ricer to break down the potatoes inside the crockpot. Pour in the warm milk-butter mixture a little at a time, stirring and mashing until you reach your preferred consistency. Fold in sour cream if using. Taste and adjust salt and pepper.
- Garnish and hold. Smooth the top, sprinkle with chopped chives, and set the crockpot to warm. If holding longer than an hour or two, stir occasionally and add a splash of warm milk if the mash thickens.
Timing & preparation notes for Easy Make Ahead Crockpot Mashed Potatoes
- Active prep time: About 15 minutes to peel and cube the potatoes and get ingredients ready.
- Cook time: 2–3 hours on HIGH or 4–5 hours on LOW (depends on your slow cooker and potato size).
- Make-ahead: You can cook these in the morning and keep them on the warm setting for a few hours. Stir occasionally to keep them creamy.
- Serving: Best served within 4 hours of finishing for ideal texture. If refrigerated, rewarm gently with a little milk or butter and stir until smooth.

Common questions and quick answers
Can I make these mashed potatoes ahead of time and reheat them?
Yes. Cool them, refrigerate in an airtight container, then reheat gently in a pot over low heat or in the crockpot on low/warm with a splash of milk or broth. Stir frequently to restore creaminess.
What’s the best potato to use?
Russets are ideal for a fluffy texture because of their higher starch content. Yukon Golds also work well for a naturally creamier, buttery flavor if you prefer that mouthfeel.
How do I keep the potatoes from getting gluey?
Don’t overwork starchy potatoes — mash until just smooth and avoid electric beaters at high speed. Warm milk and butter incorporated gradually helps create creaminess without overworking the starches.
There you have it — a hands-off, reliable way to make crowd-pleasing mashed potatoes with minimal fuss. The crockpot method is forgiving and perfect when you need to free up stove space or want to prepare ahead. Enjoy serving these warm, creamy potatoes alongside roasted meats, gravy, or your favorite holiday mains.

Easy Make Ahead Crockpot Mashed Potatoes
Ingredients
- 3 pounds russet potatoes
- 1/2 cup unsalted butter
- 1 cup whole milk
- 1/2 cup sour cream
- 4 cloves garlic
- 1 cup low-sodium chicken broth
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 2 tablespoons chopped chives
- 4 ounces cream cheese
Instructions
- Prepare the potatoes: Peel the russets and cut them into roughly 1- to 1½-inch cubes so they cook evenly in the crockpot.
- Load the crockpot: Place the potato cubes in the crockpot insert. Add the minced or smashed garlic, chicken broth, and 1/2 teaspoon of the salt. Toss gently to distribute.
- Slow cook: Cover and cook on HIGH for 2 to 3 hours or on LOW for 4 to 5 hours, until the potatoes are fork-tender and easily mashable. Cooking time depends on your slow cooker and the size of the cubes.
- Drain and return: Carefully drain any excess cooking liquid (reserve a little if you like a looser mash) and put the potatoes back in the crockpot on the warm setting.
- Warm the dairy: In a small saucepan or microwave-safe bowl, warm the milk and butter until the butter is melted and the mixture is hot but not boiling. If using cream cheese, add it now so it softens and blends easily.
- Mash to your preferred texture: Using a potato masher or ricer, mash the potatoes directly in the crockpot. Pour in the warmed milk-and-butter mixture a little at a time until you reach your desired creaminess. Stir in sour cream if using. Season with the remaining salt and black pepper to taste.
- Finish and keep warm: Smooth the surface, sprinkle with chopped chives, and set the crockpot to the 'warm' setting if you’re serving later. If you plan to hold the potatoes for more than 2 hours, check occasionally and stir gently to keep them creamy — add a splash of warm milk if they thicken.
