Preparation Time

• Prep Time: 15 minutes
• Cook Time: 4–5 hours on LOW or 2–3 hours on HIGH
• Total Time: Approximately 4 hours 15 minutes to 5 hours 15 minutes on LOW
• Servings: 6–8

Ingredients

• 3 lbs sweet potatoes, peeled and cubed
• 2 tablespoons olive oil
• ½ cup packed brown sugar
• 1½ teaspoons ground cinnamon
• ½ teaspoon salt
• ¼ teaspoon black pepper
• 1 cup mini marshmallows
• ½ cup chopped pecans
• 2 tablespoons butter, optional

Instructions

1. Prepare the Sweet Potatoes

Peel the sweet potatoes and cut them into evenly sized cubes, approximately 1 inch each. Keeping the pieces similar in size helps them cook evenly and become tender at the same time.

2. Season the Potatoes

Place the cubed sweet potatoes in a large mixing bowl. Drizzle with olive oil, then sprinkle with cinnamon, salt, and black pepper.

Toss everything together until the potatoes are evenly coated.

3. Transfer to the Crock Pot

Lightly grease the inside of your slow cooker with cooking spray or a little oil. Transfer the seasoned sweet potatoes into the crock pot and spread them into an even layer.

4. Add the Brown Sugar

Sprinkle the packed brown sugar evenly over the sweet potatoes. If you’re using butter, cut it into small pieces and scatter it over the top.

As the potatoes cook, the sugar and butter will melt together with their natural juices, creating a delicious sweet coating.

5. Slow Cook Until Tender

Cover and cook on LOW for 4–5 hours or HIGH for 2–3 hours, until the sweet potatoes are fork-tender.

Cooking times can vary depending on your slow cooker and the size of your potato cubes. If possible, gently stir once halfway through cooking to distribute the brown sugar mixture.

6. Add the Pecans and Marshmallows

During the last 15–20 minutes of cooking, sprinkle the chopped pecans and mini marshmallows evenly over the sweet potatoes.

Replace the lid and continue cooking until the marshmallows are soft, puffy, and gooey. Keep an eye on them so they don’t become overly melted.

7. Serve Warm

Remove the lid and let the dish rest for a few minutes. You can gently stir the sweet potatoes if you prefer the marshmallows mixed throughout, or leave them beautifully layered on top.

Serve warm as a sweet and comforting side dish alongside roasted turkey, glazed ham, baked chicken, or your favorite holiday main course.

Tips for the Best Crock Pot Sweet Potatoes

1. Cut evenly: Similar-sized cubes cook more consistently.
2. Choose firm sweet potatoes: Avoid potatoes with soft spots or shriveled skin.
3. Don’t skip the seasoning: A little salt balances the sweetness of the brown sugar.
4. Use fresh cinnamon: Freshly opened cinnamon gives the dish a warmer aroma.
5. Pack the brown sugar: This ensures you’re measuring the correct amount.
6. Grease the slow cooker: This helps prevent sticking and makes cleanup easier.
7. Avoid overcrowding: Spread the potatoes evenly for more consistent cooking.
8. Keep the lid closed: Every time you lift the lid, heat escapes and cooking slows down.
9. Check for doneness: A fork should slide easily into the sweet potato cubes.
10. Stir gently: Sweet potatoes soften as they cook, so avoid breaking them apart.
11. Add marshmallows near the end: This keeps them soft and gooey instead of disappearing into the sauce.
12. Toast the pecans: Toasting them briefly before adding gives them a deeper nutty flavor.
13. Use dark brown sugar: It creates a richer, deeper caramel-like flavor.
14. Adjust the sweetness: Reduce the brown sugar slightly if you prefer a less sweet side dish.
15. Add butter for richness: Butter gives the brown sugar mixture a more traditional casserole flavor.
16. Don’t add too much liquid: Sweet potatoes release moisture as they cook, so extra liquid usually isn’t necessary.
17. Use a liner if desired: A slow cooker liner can make cleanup easier.
18. Let it rest briefly: A few minutes of resting helps the sauce settle before serving.
19. Keep toppings separate for transport: If taking this dish to a gathering, consider adding the marshmallows shortly before serving.
20. Serve while warm: The marshmallows are at their softest and most delicious right after cooking.

Easy Variations

• Maple Sweet Potatoes: Replace part of the brown sugar with pure maple syrup for a lovely maple flavor.
• Walnut Topping: Substitute chopped walnuts for pecans.
• Extra Marshmallow Topping: Add another handful of mini marshmallows if you love a thick, gooey topping.
• Vanilla Cinnamon: Stir in ½ teaspoon vanilla extract near the end of cooking.
• Brown Butter Flavor: Brown the butter in a small saucepan before adding it to the slow cooker.
• A Little Spice: Add a pinch of nutmeg or ground ginger along with the cinnamon.
• Orange Cinnamon: Add a little orange zest for a bright citrus note.
• Less Sweet Version: Reduce the brown sugar and let the natural sweetness of the potatoes shine.

Make-Ahead Instructions

You can prepare the sweet potatoes ahead of time to make holiday cooking easier.

Peel and cube the sweet potatoes up to one day in advance. Store them submerged in cold water in an airtight container in the refrigerator. Drain and thoroughly dry them before seasoning and adding them to the slow cooker.

You can also measure the brown sugar, cinnamon, salt, and pepper ahead of time and keep them together in a small airtight container.

For the best texture, add the marshmallows and pecans toward the end of cooking rather than preparing the finished dish too far in advance.

Storage Instructions

Allow leftover sweet potatoes to cool slightly, then transfer them to an airtight container.

• Refrigerator: Store for up to 3–4 days.
• Freezer: Freeze the sweet potatoes without the marshmallow topping for up to 2 months for best quality. The texture may soften slightly after thawing.
• Thawing: Defrost overnight in the refrigerator before reheating.

The marshmallows may change texture during storage, so adding fresh marshmallows when reheating is a great way to bring back that gooey topping.

How to Reheat

Microwave: Place an individual portion in a microwave-safe dish. Cover loosely and heat in short intervals, stirring gently until warmed through.

Oven: Transfer the sweet potatoes to an oven-safe baking dish, cover with foil, and warm at 325°F until heated through. Add fresh marshmallows during the last few minutes if desired.

Slow Cooker: For a larger quantity, transfer the leftovers to a greased slow cooker and heat on LOW until hot throughout. Stir gently and add fresh toppings near the end.

Avoid reheating repeatedly. Warm only the portion you plan to serve.

Frequently Asked Questions

1. Can I use canned sweet potatoes?

Fresh sweet potatoes are recommended because they hold their shape better during slow cooking. Canned sweet potatoes are already cooked and may become mushy if cooked for several hours.

2. Do I have to peel the sweet potatoes?

Peeling is recommended for a softer, more traditional casserole texture. You can leave the skin on if you prefer a more rustic dish, but scrub the potatoes thoroughly first.

3. Can I cook this recipe on HIGH?

Yes! Cook on HIGH for approximately 2–3 hours, checking for tenderness toward the end.

4. How do I know when the sweet potatoes are done?

Insert a fork into a few cubes. They should be tender and easy to pierce without completely falling apart.

5. Can I make this without marshmallows?

Absolutely. Simply leave them out and enjoy the cinnamon brown sugar sweet potatoes with the crunchy pecan topping.

6. Can I use large marshmallows?

Yes. Cut them into smaller pieces so they melt more evenly over the potatoes.

7. Can I leave out the pecans?

Of course! The recipe is delicious without nuts. You can also replace them with chopped walnuts or omit the crunchy topping entirely.

8. Can I use walnuts instead of pecans?

Yes. Walnuts are an excellent substitute and pair wonderfully with cinnamon and brown sugar.

9. Can I use white sugar instead of brown sugar?

You can, but brown sugar gives the recipe a deeper caramel-like flavor. If using white sugar, expect a slightly different taste.

10. Is the butter necessary?

No. The butter is optional. It adds richness, but the sweet potatoes will still taste delicious without it.

11. Can I use coconut oil instead of olive oil?

Yes. Melted coconut oil works well and adds a subtle flavor that complements the sweet potatoes.

12. Can I prepare this the night before?

You can peel and cube the potatoes the night before and refrigerate them in water. Drain and dry them before cooking.

13. Can I double the recipe?

Yes, provided your slow cooker is large enough. Avoid filling it beyond its recommended capacity, and allow extra cooking time if needed.

14. Can I make this recipe less sweet?

Yes. Reduce the brown sugar or leave off the marshmallows. The sweet potatoes have plenty of natural sweetness.

15. Why are my sweet potatoes mushy?

They may have been cut too small or cooked too long. Check them toward the lower end of the suggested cooking time.

16. Why are my sweet potatoes still firm?

The cubes may be too large, or your slow cooker may run cooler than average. Continue cooking and check again in 20–30 minutes.

17. Do I need to add water to the crock pot?

No. The sweet potatoes release moisture as they cook, and the brown sugar creates a syrupy coating.

18. Can I freeze the leftovers?

Yes. Freeze the sweet potatoes without the marshmallow topping for the best texture. Thaw in the refrigerator before reheating.

19. Can I keep the sweet potatoes warm before dinner?

Yes. Once fully cooked, use your slow cooker’s WARM setting for a short serving period. Avoid leaving them warm for an extended time, as the texture can deteriorate.

20. Are these sweet potatoes a side dish or dessert?

They’re traditionally served as a sweet side dish, especially during holiday meals, but their brown sugar, cinnamon, and marshmallow topping also make them feel like a dessert!
