When the weather shifts and the evenings grow cozier, I reach for recipes that feel like a warm hug. The Bourbon Sweet Potato Casserole with Pecan Streusel fits the bill perfectly. It’s not about drama or fuss; it’s a straightforward dish that delivers comfort with a gentle nod to something a little more grown-up. The bourbon adds depth, while the pecan streusel provides a satisfying crunch that contrasts with the creamy sweet potatoes. This dish works nicely as a side, especially around family dinners or holiday gatherings, but it also stands up to a simple weeknight, depending on what you pair it with.

Ingredients for this Bourbon Sweet Potato Casserole with Pecan Streusel

You’ll need a handful of pantry staples and a couple of sweet potatoes. The streusel topping is where the texture comes from—flour, brown sugar, pecans, and butter come together to form a crumbly, toasty layer.

2 pounds sweet potatoes, peeled and cubed
1 egg, lightly beaten
1/2 cup bourbon
1/4 cup brown sugar
1/4 cup maple syrup
1/2 cup whole milk
1 teaspoon vanilla extract
1/2 teaspoon salt
1/2 cup all-purpose flour
1/3 cup brown sugar
4 tablespoons unsalted butter, cold and diced
1/3 cup pecans, chopped

Instructions

Preheat the oven to 375°F (190°C). Lightly grease an 8×8-inch baking dish.
Boil or steam the cubed sweet potatoes until tender, about 12–15 minutes. Drain well and mash until smooth, leaving a few small lumps if you like texture.
In a large bowl, whisk together the mashed sweet potatoes, egg, bourbon, brown sugar, maple syrup, milk, vanilla, and salt until creamy. Taste and adjust as needed.
Pour the mixture into the prepared dish and spread evenly with a spatula.
Make the streusel: mix flour, brown sugar, chopped pecans, and cold butter. Work until the mixture resembles coarse crumbs with some pea-sized bits of butter.
Evenly sprinkle the streusel over the potato base.
Bake for 25–30 minutes, until the streusel is golden and the casserole is heated through. Optional: a quick broil for 1–2 minutes to deepen color—watch carefully to prevent burning.
Let rest for about 5 minutes before serving to help it set and slice neatly.

Nutritional information

Per serving: approximately 420 calories. This is a ballpark figure that will vary slightly depending on the exact sizes of potatoes and the amount of streusel you use. If you’re watching sugar or alcohol, you can reduce the bourbon to 1–2 tablespoons and increase the milk a touch to maintain creaminess.

Frequently asked questions

Can I make this ahead?

Yes. You can assemble the casserole up to a day in advance. Cover tightly and refrigerate. Bring to room temperature for about 20–30 minutes before baking, then bake as directed. If you’re reheating from cold, you may need an extra 5–10 minutes in the oven.

Is there a non-alcoholic alternative?

Absolutely. Use 1–2 tablespoons of apple cider vinegar or orange juice for acidity, and replace the bourbon with an equal amount of apple juice or a splash of vanilla extract to keep the flavor round without the kick.

What should I serve with it?

This casserole pairs nicely with roasted turkey, grilled chicken, or a hearty vegetarian main like mushroom ragout. A simple green salad or steamed green beans adds balance. If you want a bit more contrast, a bright cranberry sauce or citrus-dressed slaw can lift the flavors nicely.

Reviewing this recipe at the end of the day, I’m reminded that the magic of this dish is in its quiet layers. The sweetness of the potatoes mingles with the warmth of the bourbon, and the pecan streusel gives a satisfying crunch. It’s approachable enough for a weeknight side and special enough to bring to a gathering. If you cook it once, you’ll likely return to it again—perhaps swapping in maple for brown sugar or using walnuts if pecans aren’t on hand. The key is to keep it simple, stay present with the rolling aromas as it bakes, and enjoy the moment around the table with people you care about.
