Ingredients
-
4 large sweet potatoes, peeled and cubed (about 2 lbs)
-
1/2 cup unsalted butter, melted
-
1/4 cup brown sugar, packed
-
1/2 teaspoon ground cinnamon
-
1/4 teaspoon ground nutmeg
-
1/4 teaspoon salt
-
1 teaspoon vanilla extract
-
1 cup mini marshmallows (or more for topping)
-
Optional: 1/4 cup chopped pecans for added crunch
Pro Tips
-
Choose the Right Sweet Potatoes – Opt for firm, evenly sized sweet potatoes to ensure uniform cooking in the crockpot.
-
Avoid Overfilling the Crockpot – Leave some space for the marshmallows to melt properly without sticking to the lid.
-
Add Marshmallows at the Right Time – Top the sweet potatoes with marshmallows in the last 15–20 minutes of cooking to achieve a perfect golden layer without burning.
Instructions
Step 1: Prep the Sweet Potatoes
Peel and cube your sweet potatoes into roughly 1-inch pieces. Even sizes ensure they cook evenly. Place them in the crockpot and drizzle with melted butter. Sprinkle the brown sugar, cinnamon, nutmeg, and salt evenly over the top, then gently stir to coat all pieces.
Step 2: Set Up the Crockpot
Cover your crockpot and cook on low for 5–6 hours or on high for 2–3 hours. The sweet potatoes should be tender and easily pierced with a fork. Avoid lifting the lid during cooking to retain heat and moisture.
Step 3: Add the Marshmallows
Once the sweet potatoes are fully cooked, sprinkle the mini marshmallows evenly on top. Cover the crockpot again and cook for an additional 15–20 minutes, or until the marshmallows are melted and lightly golden. For extra flair, you can quickly broil the marshmallows in the oven for 1–2 minutes to achieve a toasted top.
Step 4: Serve and Enjoy
Gently stir the sweet potatoes if desired, but leave some marshmallows on top for presentation. Scoop onto plates or serve family-style in the crockpot. Optionally, sprinkle chopped pecans over the top for added crunch and flavor.

Variations
-
Vegan Version: Substitute butter with coconut oil and use vegan marshmallows to make this dish entirely plant-based.
-
Spiced Up: Add a pinch of cayenne pepper or ground ginger to the sweet potato mixture for a warm, spicy twist.
-
Maple-Glazed: Replace brown sugar with pure maple syrup for a richer, more complex sweetness that pairs beautifully with marshmallows.
Storage and Serving
Store leftover Crockpot Sweet Potatoes with Marshmallows in an airtight container in the refrigerator for up to 3 days. Reheat gently in the microwave or stovetop until warm, adding a few extra marshmallows on top for freshness. Serve alongside roasted turkey, glazed ham, or even as a standalone side dish. For a festive touch, sprinkle with toasted pecans or a drizzle of maple syrup before serving.
FAQs
1. Can I make this recipe ahead of time?
Yes, you can prep the sweet potatoes and seasonings in advance, then store them in the fridge. Add marshmallows just before cooking.
2. Can I freeze cooked sweet potatoes with marshmallows?
It’s best to freeze only the cooked sweet potatoes without marshmallows. Add marshmallows after thawing and reheating.
3. What size crockpot works best?
A 4–6 quart crockpot is ideal for this recipe to ensure even cooking and prevent overflow when marshmallows are added.
4. Can I use large marshmallows?
Mini marshmallows work best for even melting. If using large ones, chop them into smaller pieces.
5. How do I prevent marshmallows from burning?
Add marshmallows at the end of cooking, and cook on low heat for the last 15–20 minutes. Optional broiling should be closely monitored.
