Ingredients You’ll Need

Here’s everything you need to make these creamy mashed potatoes in the slow cooker:

• 5 lbs baking potatoes (Yukon Gold or Russets), peeled and cut into 1-inch chunks
• 1½ cups chicken broth
• ¼ cup butter, cut into chunks
• 1 (8 oz) block cream cheese
• 1 tsp garlic powder
• 1 tsp onion powder
• ½ tsp salt
• ¼ tsp ground black pepper
• ½ to 1 cup warm milk (or half-and-half)

Tip: For extra richness, warm your milk or half-and-half before adding it to the potatoes.

How to Make the Best Slow Cooker Mashed Potatoes

This recipe is so easy you’ll wonder why you haven’t been doing it this way all along.

Step 1: Load Up the Slow Cooker

1. Place the peeled, chopped potatoes in a 4 to 5-quart slow cooker.
2. Pour in the chicken broth.
3. Dot the potatoes with butter chunks.

And Step 2: Cook Until Tender

4. Cover and cook on HIGH for 4 to 4.5 hours.
5. The potatoes should be fork-tender and easy to mash.

No peeking! Keep the lid closed for the full cook time to trap in the steam.

Step 3: Mash and Flavor

6. Add cream cheese, garlic powder, onion powder, salt, and pepper.
7. Use a potato masher for rustic texture, or a hand mixer on LOW for a smoother finish.

Avoid overmixing. Too much blending can turn mashed potatoes into glue.

And Step 4: Add Milk & Adjust

8. Slowly stir in warm milk, starting with ½ cup.
9. Add more until you reach your perfect level of creaminess.

Step 5: Keep Warm and Serve

10. Cover and keep on LOW or WARM for up to 2 hours.
11. Stir gently before serving.

Hosting tip: Transfer to a pretty serving bowl just before guests arrive, or serve straight from the crock for easy cleanup.

Make-Ahead and Meal Prep Tips

The best thing about this make ahead crockpot mashed potatoes recipe? It works so well for holidays and busy meal prep.

Here’s how I do it:

• Chop ahead: Peel and dice potatoes the day before, store in cold water in the fridge.
• Fully prep: Make the mashed potatoes a day in advance and refrigerate.
• Reheat: Warm in the slow cooker on LOW with a splash of milk or broth. Stir occasionally.

Flavor Variations to Try

This basic version is perfect, but sometimes I like to mix things up. Try these tasty upgrades:

• Roasted garlic – Stir in mashed roasted garlic cloves for extra depth
• Fresh herbs – Add chopped chives, parsley, or rosemary
• Parmesan cheese – Mix in ½ cup for a salty, nutty twist
• Sour cream – Replace some cream cheese with sour cream for tang

Want more indulgence? Try using heavy cream instead of milk.
