Sweet Potato Mix

Chef’s Tip: For the best flavor, always choose fresh, firm sweet potatoes. Draining the pineapple well is crucial to prevent the casserole from becoming watery. Unsalted butter allows you to control the overall saltiness of the dish.

Pecan Topping

Chef’s Tip: Lightly toasting the pecans before chopping can enhance their nutty flavor. Ensure the butter is fully melted and thoroughly mixed with the dry ingredients to create that perfect crumbly topping.

Instructions

  1. Prepare the Sweet Potatoes

    Preheat your oven to 350°F (175°C). Begin softening the sweet potatoes using your preferred method. You can boil them: peel and chop them into large chunks, then boil in lightly salted water until fork-tender (about 15-20 minutes). Alternatively, microwave them: prick whole sweet potatoes several times with a fork and microwave for 5-10 minutes, or until soft. For an Instant Pot method (see video below), cook whole, unpeeled sweet potatoes on high pressure for 10-15 minutes with 1 cup of water, followed by a natural release. Remove the skin after softening, if you haven’t already. The goal is perfectly tender sweet potatoes that are easy to mash.

  2. Create the Sweet Potato Base

    Once the sweet potatoes are soft and peeled, transfer them to a large mixing bowl. Add the drained crushed pineapple, 3 tablespoons of melted unsalted butter, 2 large eggs, 2 tablespoons of all-purpose flour, ½ teaspoon of salt, 1 tablespoon of granulated sugar, and 1 teaspoon of vanilla extract. Using a potato masher or an electric mixer, thoroughly mash and mix all the ingredients until smooth and well combined. Ensure there are no large lumps for a creamy consistency. Pour this sweet potato mixture into a greased 9×13 inch baking dish, spreading it evenly.

  3. Prepare the Pecan Topping

    In a separate medium bowl, combine the 2 cups of chopped pecans, ½ cup of packed light brown sugar, ⅓ cup of all-purpose flour, and 5 tablespoons of melted unsalted butter. Mix these ingredients well with a fork until the pecans are thoroughly coated and the mixture resembles coarse crumbs. This creates that wonderfully crunchy and buttery layer. Evenly sprinkle this pecan topping over the sweet potato mix in the baking dish, covering the entire surface.

  4. Bake and Serve

    Place the baking dish in the preheated oven and bake for 25-35 minutes, or until the topping is golden brown and the sweet potato mixture is bubbly around the edges. The aroma filling your kitchen will be incredible! Once baked, carefully remove the casserole from the oven and let it cool for a few minutes before serving. This allows it to set slightly. Enjoy this delightful Southern Sweet Potato Casserole warm as a fantastic side dish for any meal!

Tips for the Best Sweet Potato Casserole

  • Choose the Right Sweet Potatoes: Look for firm, unblemished sweet potatoes (often called yams in the US for their orange flesh). The fresher they are, the sweeter and more flavorful your casserole will be.
  • Perfectly Mash: For an ultra-smooth casserole, use an electric mixer or a food processor to mash your cooked sweet potatoes. If you prefer a slightly chunkier texture, a hand masher works great.
  • Don’t Overmix: Once the eggs are added, mix just until combined. Overmixing can lead to a tougher texture.
  • Sweetness Adjustment: The recipe provides a balanced sweetness. If your sweet potatoes are exceptionally sweet, you might reduce the added sugar slightly, or increase it if you prefer a sweeter dish.
  • Pineapple Power: The crushed pineapple adds a lovely tang and moisture that prevents the casserole from being overly heavy. Ensure it’s well-drained to maintain the desired consistency.

Variations to Try

  • Marshmallow Topping: For a more traditional sweet potato casserole, omit the pecan topping and instead, top the casserole with 2-3 cups of mini marshmallows during the last 10 minutes of baking, or until golden brown and puffed.
  • Streusel Topping: If you’re not a fan of pecans, you can create a simple streusel topping with oats, brown sugar, flour, and cinnamon for a different texture.
  • Spice It Up: Add a pinch of cinnamon, nutmeg, or allspice to the sweet potato mix for an extra layer of warm, autumnal flavor.
  • Nutty Alternatives: Walnuts or even candied pecans can be substituted for the chopped pecans in the topping.

Make-Ahead & Storage Instructions

Make Ahead

This sweet potato casserole is an excellent make-ahead dish, perfect for easing holiday stress.

  • Prepare the Base: You can prepare the sweet potato mixture up to 2 days in advance. Store it covered in an airtight container in the refrigerator.
  • Prepare the Topping: The pecan topping can also be made ahead and stored separately in an airtight container at room temperature for up to 2 days.
  • Assemble and Bake Later: Assemble the casserole with the topping just before baking. If baking from cold, you might need to add an extra 10-15 minutes to the baking time.

Storage

  • Refrigerator: Leftover sweet potato casserole can be stored in an airtight container in the refrigerator for 3-4 days.
  • Freezer: To freeze, let the casserole cool completely. You can freeze the entire casserole (covered tightly with plastic wrap and foil) or individual portions in freezer-safe containers for up to 2-3 months. Thaw overnight in the refrigerator before reheating.

Reheating

Reheat individual portions in the microwave until warm through. For a whole casserole, cover with foil and reheat in a 300°F (150°C) oven until warmed, then uncover for the last few minutes to crisp up the topping if needed.

Serving Suggestions

Southern Sweet Potato Casserole is incredibly versatile and pairs wonderfully with a variety of meals, especially during the festive season.

  • Holiday Feast: It’s the quintessential side dish for roasted turkey, baked ham, or beef roasts during Thanksgiving and Christmas.
  • Sunday Supper: Serve it alongside roasted chicken, pork loin, or even a hearty pot roast for a comforting family meal.
  • Potlucks: This casserole is always a crowd-pleaser at gatherings and potlucks.
  • Brunches: A smaller portion can even be a delightful addition to a savory brunch spread.

Frequently Asked Questions (FAQ)

Can I use canned sweet potatoes for this recipe?
While fresh sweet potatoes are recommended for the best flavor and texture, you can use canned sweet potatoes if needed. Be sure to drain them very well and adjust the sugar content as canned sweet potatoes are often packed in syrup and can be much sweeter.
Can I make this casserole dairy-free?
Yes, you can! Simply substitute the unsalted butter with a high-quality plant-based butter alternative. The texture and flavor will remain largely similar.
My casserole seems a bit runny. What went wrong?
This usually happens if the sweet potatoes weren’t drained enough or if the crushed pineapple wasn’t thoroughly drained. Ensuring all liquid is removed from the pineapple is key. Also, make sure your eggs are properly incorporated, as they help bind the mixture.
How do I prevent the pecan topping from burning?
If your topping is browning too quickly, you can lightly tent the casserole with aluminum foil for the remaining baking time. This protects the topping while allowing the sweet potato base to finish cooking.
