Slow Cooker Sweet Potato Casserole. This is a convenient and delicious alternative to the traditional Sweet Potato Casserole version.

Serve it alongside creamy mashed potatoes, a cheesy green bean casserole, and, of course, the classic Thanksgiving stuffing. The flavors and textures of this casserole will blend harmoniously with the rest of the meal. The slow cooker method allows the sweet potatoes to cook slowly and evenly, resulting in a tender and flavorful casserole.

The natural sweetness of the potatoes shines through, enhanced by the gentle cooking process. The aroma that fills your kitchen as it cooks is simply irresistible. To prepare this dish, start by rinsing the sweet potatoes and peeling off the tough skin. Then, cut them into uniform cubes, around 1 inch in size, to ensure even cooking.

Place the sweet potato cubes in the crockpot and let the magic happen. With minimal effort, you can have a delectable Sweet Potato Casserole that will impress your guests. The slow cooker does all the work for you, allowing you to focus on other aspects of your Thanksgiving feast. So, sit back, relax, and let the crockpot work its magic while you enjoy the holiday with your loved ones.

Preparing Sweet Potatoes for Casserole

To prepare the sweet potatoes for the casserole, there are a few simple steps you need to follow. First, it’s important to remove the tough skin from the sweet potatoes. This can be done by rinsing the sweet potatoes under cold water to remove any dirt or debris, and then peeling them entirely.

  1. By removing the skin, you’ll ensure a smooth and creamy texture in the final dish. Once the sweet potatoes are peeled, the next step is to cut them into uniform cubes. This is important because it allows the sweet potatoes to cook evenly in the slow cooker. Aim for cubes that are around 1 inch in size.
  2. By cutting them into uniform pieces, you’ll ensure that each cube cooks at the same rate, resulting in a perfectly tender and flavorful casserole. After the sweet potatoes are peeled and cubed, it’s time to add them to the crockpot. Simply toss the cubes into the slow cooker and let the magic happen. The slow cooker will do all the work for you, cooking the sweet potatoes to perfection while you attend to other tasks.
  3. By following these simple steps, you’ll have perfectly prepped sweet potatoes ready to be transformed into a delicious and comforting casserole. So go ahead, peel, cube, and let the crockpot work its magic. Your taste buds will thank you.

How Long to Cook Sweet Potato Casserole in a Slow Cooker

To ensure that your sweet potato casserole is cooked to perfection in a CrockPot, you have two options: cooking on low or cooking on high. If you have the time and prefer a slow-cooked result, cooking on low is the way to go. Simply set your CrockPot to low and let the sweet potatoes cook overnight or while you’re at work for approximately 8 hours.

This low and slow method will result in tender and creamy sweet potatoes that are bursting with flavor. On the other hand, if you’re in a bit of a hurry and need your sweet potato casserole ready sooner, you can opt for cooking on high. Set your CrockPot to high and let the sweet potatoes cook for about 4 hours.

This higher temperature will expedite the cooking process while still ensuring that your sweet potatoes are cooked through and soft. Regardless of which cooking method you choose, both will yield perfectly cooked sweet potatoes that are ready to be transformed into a delicious casserole.

And don’t forget to add the pecan topping at the end to add a delightful crunch and sweetness to your dish. When it comes to mashing the sweet potatoes, you have options as well. If you prefer a slightly chunky texture, you can use a potato masher to smash the sweet potatoes.

For a smoother consistency, use a hand mixer or an immersion blender to achieve that velvety texture. With these cooking and mashing tips, you’ll be able to create a mouthwatering sweet potato casserole that will impress your family and friends. Enjoy!

For the perfect finishing touch to your slow cooker sweet potato casserole, there are a variety of delicious toppings you can choose from. One option is a buttery brown sugar pecan topping, which adds a delightful crunch and sweetness to the dish.

Simply combine melted butter, brown sugar, and chopped pecans, and sprinkle it over the casserole before serving. The combination of the buttery richness, the caramel-like sweetness of the brown sugar, and the nutty crunch of the pecans creates a mouthwatering contrast to the creamy sweet potatoes.

If you’re a fan of marshmallows, you can easily incorporate them into your sweet potato casserole as well. Just add the marshmallows to the slow cooker during the last 5 minutes of cooking and close the lid. The heat from the slow cooker will melt and soften the marshmallows, creating a gooey and sweet topping that pairs perfectly with the creamy sweet potatoes.

Another option for a delicious topping is a streusel topping. To make this, combine flour, brown sugar, butter, and a pinch of cinnamon until crumbly. Sprinkle the streusel over the sweet potato casserole before cooking, and it will bake into a crispy and flavorful topping that adds a delightful texture to each bite.

Whether you choose the buttery brown sugar pecan topping, marshmallows, or a streusel topping, these additions will take your slow cooker sweet potato casserole to the next level. Experiment with different combinations to find your favorite, and enjoy the delicious flavors and textures they bring to this classic dish.

How to Store Leftovers

To ensure the longevity of your slow cooker sweet potato casserole, it’s important to know how to store the leftovers properly. Whether you have a small portion or a large batch, there are a few options for storing and reheating your delicious dish.

The easiest way to store leftovers is in the refrigerator. Simply transfer the sweet potato casserole into an airtight container and place it in the fridge. It can be stored for up to 5 days, allowing you to enjoy the leftovers throughout the week. When you’re ready to enjoy it again, simply take it out of the fridge, give it a quick stir, and heat it in the microwave.

For an extra burst of flavor, you can sprinkle a dash of pumpkin pie spice on top before reheating. If you have a surplus of sweet potato casserole or want to save it for a later date, freezing is a great option. Scoop the casserole into a zippered bag or a freezer container, making sure to label it with the date.

It can be stored in the freezer for several months.

When you’re ready to enjoy it, thaw it in the refrigerator overnight and then reheat it in the microwave or oven. By following these storage and reheating tips, you can enjoy your slow cooker sweet potato casserole for days to come.

Whether you choose to store it in the fridge or freezer, you’ll be able to savor the flavors and warmth of this comforting dish whenever you desire.
