What You’ll Need to Make Air Fryer Sweet Potato Casserole

How to Make Air Fryer Sweet Potato Casserole

Step One: In a large mixing bowl, mash the sweet potatoes using a fork or potato masher until smooth.

Step Two: Add the melted butter, brown sugar, vanilla extract, salt, pepper, and ground cinnamon, then mix until well combined. Gently fold in the diced pecans for added crunch.
Step Three: Lightly grease your casserole dish with non-stick cooking spray or olive oil spray. Transfer the sweet potato mixture into the prepared dish, spreading it evenly.
Sprinkle the mini marshmallows on top for a gooey, golden finish. Place the dish in the air fryer and cook at air fryer temperature of 320 degrees F and set cook time for 10-12 minutes, or until the marshmallows are toasted.

Air Fryer Sweet Potato Casserole Recipe Tips
- Choose the Right Sweet Potatoes: Select sweet potatoes that are firm and without blemishes for the best texture and flavor. Air frying or boiling them will ensure they’re soft enough for mashing.
- Customize the Topping: You can swap the mini marshmallows for a crunchy pecan topping, or add both for extra texture. If you prefer a more savory touch, try topping it with shredded cheese or crispy fried onions.
- Monitor Cooking Time: Air fryer models vary, so check your casserole halfway through to ensure it’s cooking evenly. If the marshmallows are browning too quickly, cover the dish loosely with foil.
Storing
- Storing: Store leftover Air Fryer Sweet Potato Casserole in an airtight container in the refrigerator for up to 3-4 days. Be sure to let it cool completely before sealing to preserve its texture.
- Freezing: To freeze, wrap the casserole tightly in plastic wrap and foil or place it in a freezer-safe container for up to 2-3 months. Thaw it overnight in the fridge before reheating.
- Reheating: Reheat in the air fryer at 320°F for 5-7 minutes, or until heated through and the marshmallows are slightly toasted. You can also reheat it in the oven at 350°F for 10-15 minutes.

Air Fryer Sweet Potato Casserole Recipe Faqs
Can I use canned sweet potatoes for this recipe? While fresh sweet potatoes yield the best texture, canned sweet potatoes can be used if needed. Just make sure to drain them well before mashing.
How do I know when the casserole is done? The casserole is done when the marshmallows are golden brown and the sweet potato mixture is heated through. You can check by inserting a fork to ensure it’s soft.
Can I make this casserole ahead of time? Yes! Prepare the sweet potato mixture and store it in the fridge for up to a day before cooking. Add the marshmallows right before air frying.
What if I don’t have mini marshmallows? You can use regular marshmallows, but cut them into smaller pieces for a similar effect. Alternatively, you can skip the marshmallows and top with more pecans.
Can I use a different type of nut for the topping? Yes! Walnuts, almonds, or even cashews work well as a substitute for pecans, giving the casserole a slightly different flavor and crunch.

Your recipe says you can roast the sweet potatoes in the air fryer too but I don’t want olive oil on sweet potatoes I’m going to put in your casserole. Can you update me on how to cook the sweet potatoes first and then make the casserole?
Laurie
If you have a microwave you can cook them in there as well. YOu won’t taste the olive oil, after the sweet potato casserole.
