This easy Sweet Potato Casserole recipe is a Thanksgiving dinner classic for a reason: everyone loves it! Perfected over the years, my version balances creamy sweet potatoes with a crunchy brown sugar streusel topping, guaranteeing it a spot on your holiday table for years to come.

Homemade Sweet Potato Casserole

No holiday menu is complete without sweet potato casserole! It’s one of those family favorites thanks to that delicious combination of fluffy sweet potatoes, caramelized brown sugar, and gooey marshmallows on top. Mmm.

My sweet potato casserole dish uses simple ingredients, and everything is made from scratch (except for the marshmallows, of course). No cans, no artificial flavors, but still approachable for the busy or novice cook. There’s also room for creativity if you want to put your own spin on it! 

Ingredients

• Milk: For a creamy, smooth consistency in your sweet potato base.
• Butter: You’ll need melted butter for the filling and cubed, cold butter for the streusel topping.
• Salt: Just a pinch of salt really brings out all the flavors in the casserole.
• Cinnamon: A dash of cinnamon adds that classic warm, cozy spice to your dish.
• Vanilla paste: I really like using vanilla paste instead of vanilla extract because it gives a richer flavor.
• Eggs: Eggs help bind everything together, giving your casserole a nice, smooth texture.
• Sweet potatoes: To make that delicious, creamy sweet potato filling.
• Brown sugar: Adds that perfect sweet kick and helps things caramelize nicely.
• Flour: A little flour helps thicken the streusel topping, making it perfectly crumbly.
• Marshmallows: I prefer mini marshmallows, but the bigger marshmallows work too.

How to Make the Best Damn Sweet Potato Casserole

Step 1: Mix the Wet Ingredients

First, crank up that oven to 375°F. Then, grab a big bowl and toss in the milk, melted butter, salt, cinnamon, vanilla paste, and eggs. Beat together until everything is nice and mixed.

Step 2: Add Sweet Potatoes

Next, add your sweet potatoes to the bowl and mash them up with a fork or potato masher until smooth. Pour the mixture into a 7×10-inch baking dish and spread it out evenly.

Step 3: Mix the Dry Ingredients

In a separate bowl, combine brown sugar, flour, and cold cubed butter. Use your fingers to mix it all together until coarse crumbles form.

Step 4: Assemble Casserole

Now let’s bring it all together. Evenly sprinkle the crumble mixture over the sweet potatoes, then top with marshmallows.

Step 5: Bake

Bake at 375°F for 25-30 minutes, or until that topping turns golden brown and those marshmallows get nice and toasty.

Step 6: Serve & Enjoy

Once the casserole is done baking, let it cool for a few minutes before serving. Enjoy!

For the main dish, try my Best Damn Oven-Roasted Turkey Breast with tender meat and crispy skin, or go for an Easy Baked Ham with Maple and Brown Sugar Glaze for a sweet and savory treat.

Pair it with sides like the tangy Best Damn Homemade Cranberry Sauce, creamy Best Damn Mashed Potatoes that practically melt in your mouth, and some warm, cozy Homemade Stuffing to bring it all together. Thanksgiving dinner? Sorted!

Storage & Reheating

To store your sweet potato casserole, keep any leftovers in an airtight container in the refrigerator for 3 to 5 days. You can also assemble the entire dish ahead of time and refrigerate it for 1-2 days before baking. 

For reheating, the oven is the best method for restoring its texture. Just cover the dish with foil and warm it at 350°F for 20-30 minutes. Then remove the foil at the end to crisp the topping. For a quick single serving, the microwave works fine, though it will result in a softer topping.
