Ingredients You’ll Need

5 pounds potatoes: Choose russet or Yukon gold for a fluffy texture.

1 cup chicken broth: This enriches the potatoes and prevents them from getting too dry.
1 cup sour cream: For a rich creaminess, sour cream makes the mash irresistibly smooth.
1/2 cup butter (1 stick): Use unsalted butter for better control over seasoning.
1.5 teaspoons salt: Essential for enhancing all the flavors.
1 teaspoon ground black pepper: Provides a nice peppery kick.
1 teaspoon oregano: Adds a subtle earthy note. You can substitute with thyme or rosemary if desired.

How to Make Make Ahead Crockpot Mashed Potatoes

Prepare the Potatoes: Peel and chop the potatoes into equal-sized pieces to ensure they cook evenly. Aim for about 1 to 2 inches in size.
Add Ingredients: Place the chopped potatoes, minced garlic, chicken broth, sour cream, butter, salt, black pepper, and oregano into the crockpot. Toss everything together gently to coat the potatoes in the seasonings.
Cook Slowly: Cover and cook on low for 6 to 8 hours, or on high for about 3 to 4 hours. The potatoes should be fork-tender when done.
Mash and Finish: Once cooked, use a potato masher to mash the potatoes directly in the crockpot. Slowly mix in milk until you reach your desired consistency. Taste and adjust seasoning if needed.
Garnish and Serve: Transfer the mashed potatoes to a serving dish, sprinkle with chopped fresh parsley, and enjoy!

Storing & Reheating

To store your mashed potatoes, let them cool to room temperature, then cover them tightly in an airtight container. They can stay at room temperature for about 2 hours before refrigeration is needed. In the fridge, they will last for up to 3 days. For longer storage, you can freeze them in a freezer-safe container for up to 3 months. When reheating, microwave in 30-second intervals or warm them on the stovetop, adding a splash of milk to revive their creamy texture.

Chef’s Helpful Tips

Be mindful of potato size; smaller pieces cook faster and more evenly.
Always room temperature your butter and sour cream for smooth mixing.
If your potatoes are too thick after mashing, gently fold in a bit more milk until creamy.
For extra flavor, consider adding cream cheese along with the sour cream.
Ensure to taste your mash before serving—adjust salt and pepper as necessary.
