Why Make This Crockpot Christmas Dinners Side Dishes Dump & Walk Easy Under $10 Feed Crowd Budget
The holidays are expensive, but this recipe keeps your costs remarkably low. Potatoes are one of the most affordable pantry staples, and when you buy them in bulk, you can feed ten people for just a few dollars. Using a crockpot frees up your precious oven and stove space for the turkey or ham. This “dump and walk” method eliminates the need to boil large pots of water, reducing the risk of burns and messy spills. It is the most efficient way to ensure a hot, delicious side dish is ready exactly when you are.
Ingredients
- 5 lbs Red or Yukon Gold potatoes, washed and cubed
- 1 cup low-sodium chicken or vegetable broth
- 1/2 cup salted butter, sliced
- 4 cloves garlic, minced
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1/2 cup milk or heavy cream
- 1/4 cup grated Parmesan cheese
- Fresh parsley for garnish (optional)
Directions
Step 1: Preparation
Wash your potatoes thoroughly under cold water. If you are using red or Yukon Gold potatoes, leave the skins on to save time and add texture. Cut the potatoes into uniform 1-inch chunks to ensure even cooking. Grease the inside of your slow cooker with cooking spray or a little butter to prevent sticking.
Step 2: Cooking
Place the cubed potatoes into the crockpot. Pour the broth over the potatoes and add the minced garlic, salt, and pepper. Lay the slices of butter across the top. Cover the slow cooker with the lid and set it to “High” for 4 hours or “Low” for 7 to 8 hours. Do not open the lid during the cooking process to keep the steam trapped inside.
Step 3: Mashing and Serving
Once the potatoes are fork-tender, turn the heat to “Warm.” Pour in the milk and add the Parmesan cheese. Use a potato masher or an electric hand mixer directly in the crockpot to mash the potatoes until they reach your desired consistency. If the mixture is too thick, add an extra splash of milk. Garnish with parsley and serve directly from the pot.
Expert Tips for Perfect Crockpot Christmas Dinners Side Dishes Dump & Walk Easy Under $10 Feed Crowd Budget
To get the best results, use Yukon Gold potatoes because they have a naturally buttery flavor and creamy texture. If you want to keep the cost under $10, look for 5-pound bags of potatoes on sale during the holiday week. Avoid over-mixing the potatoes with an electric mixer, as this can make them gluey; a manual masher often yields the best “home-style” fluffiness. If you are feeding an especially large crowd, you can easily double the recipe in a 6-quart or larger slow cooker. Always keep the crockpot on the “Warm” setting during dinner to ensure second helpings are just as delicious as the first.
Delicious Variations
- Loaded Potatoes: Stir in crispy bacon bits, shredded cheddar cheese, and chopped green onions just before serving.
- Vegan Friendly: Swap the butter for olive oil or vegan margarine and use almond milk and nutritional yeast instead of dairy and Parmesan.
- Herb Infused: Add fresh rosemary and thyme sprigs to the pot during the cooking phase, then remove the woody stems before mashing.
- Sour Cream Kick: Replace half of the milk with sour cream or plain Greek yogurt for a tangier, richer flavor profile.
Frequently Asked Questions
Do I need to peel the potatoes first?
No, peeling is optional! Using red or Yukon Gold potatoes allows you to leave the skins on, which adds nutrients and saves a significant amount of prep time. If you prefer perfectly smooth potatoes, you can peel them, but it isn’t necessary for this dump-and-walk method.

Can I make these mashed potatoes ahead of time?
Yes, you can make them up to two days in advance. Store them in an airtight container in the fridge. When you are ready to serve, place them back in the crockpot with a splash of milk or a knob of butter on “Low” for about an hour until heated through.
What if my potatoes are too watery?
If you find there is too much liquid after cooking, simply mash them first and let them sit uncovered on the “High” setting for 15 minutes. This allows excess moisture to evaporate. You can also stir in a tablespoon of instant potato flakes to thicken the texture instantly.
Can I use water instead of broth?
You can use water, but broth adds a much deeper flavor profile to the potatoes. If you use water, be sure to add a bit more salt or a bouillon cube to ensure the dish doesn’t taste bland. The broth is the secret to that “restaurant-quality” taste on a budget.
How long can I keep these on the “Warm” setting?
You can safely keep mashed potatoes on the “Warm” setting for up to 4 hours. If they start to look dry, simply stir in a little more warm milk or a tablespoon of butter to loosen the texture and restore the creaminess.
