Slow-Cooker Sweet-Potato & Sage Mash
Creamy, aromatic, and hands-free—perfect for holiday feasts.
🛒 Ingredients
- - 3 lbs sweet potatoes (about 4 medium), peeled and cubed
- - 1/2 cup (1 stick) unsalted butter
- - 1 cup whole milk (or heavy cream for richer texture)
- - 1 tbsp fresh sage, chopped (or 1 tsp dried)
- - 1 tsp salt
- - 1/2 tsp black pepper
👨🍳 Instructions
Prepare Sweet Potatoes: Place cubed sweet potatoes in a large bowl. Add butter, milk, sage, salt, and pepper. Toss to coat evenly.
💡 Use a wire whisk to ensure the butter and milk are fully incorporated into the sweet potato cubes.
Slow Cook: Transfer mixture to a 6-quart slow cooker. Cover and cook on LOW for 6-8 hours or until sweet potatoes are tender and mash easily with a fork.
💡 Check for doneness by piercing a sweet potato cube with a fork—it should go in effortlessly.
Mash: Use a potato masher or immersion blender to achieve your desired consistency. For extra smooth texture, strain through a fine mesh sieve.
💡 Add more milk or butter as needed to reach your preferred consistency.
Serve: Garnish with additional sage leaves and a drizzle of melted butter. Serve warm alongside your main course.
💡 For a festive touch, sprinkle with a bit of fresh thyme or rosemary.

Ingredient Notes & Substitutions
Sweet Potatoes
Sweet potatoes provide natural sweetness and a creamy texture when cooked. For a spudier texture, use regular potatoes, but they won't absorb the sage as well.
Substitutions: Regular potatoes (adjust cooking time), butternut squash (for a sweeter flavor).
Fresh Sage
Fresh sage adds a vibrant, earthy flavor that can't be replicated with dried. The slow-cooker allows the sage to infuse the mash gradually.
Substitutions: Dried sage (use 1 tsp), rosemary, or thyme for a different herbal note.
Butter
Butter adds richness and helps the sage flavor meld into the mash. For a lighter version, use half butter and half olive oil.
Substitutions: Vegan butter (for dairy-free), ghee (for a nutty flavor).
Milk
Milk adds creaminess without overwhelming the sweet potato flavor. For a richer texture, use heavy cream or half-and-half.
Substitutions: Coconut milk (for a dairy-free option), almond milk (add a pinch of cinnamon).
Pro Tips for Perfect Sweet-Potato Mash
🧂 Flavor Boost
Add a pinch of nutmeg or a splash of balsamic vinegar for extra depth. Taste and adjust seasoning before serving.
🥄 Texture Control
For ultra-smooth mash, strain through a sieve after mashing. For rustic texture, leave chunks of sweet potato.
❄️ Make-Ahead Tip
Prepare the slow cooker 24 hours in advance and refrigerate. Reheat on LOW for 2 hours before serving.
🍁 Garnish Ideas
Sprinkle with toasted pecans, a dollop of sour cream, or a swirl of cranberry sauce for festive flair.
Variations & Customizations
Garlic & Herb Twist
Add 2 minced garlic cloves and 1 tsp dried thyme to the slow cooker for a savory upgrade.
Spicy Version
Stir in 1/2 tsp cayenne pepper or a diced jalapeño for a warm, spicy kick.
Vegan Adaptation
Use vegan butter, coconut milk, and skip the butter topping. Add nutritional yeast for umami flavor.
Citrus Zest
Grate the zest of 1 orange or lemon into the mash for a bright, refreshing contrast.
