Ingredients List

ingredients to make air fryer sweet potato casserole
  • 40-ounce can cut sweet potatoes (in water)
  • ¼ cup butter, melted
  • ¼ cup brown sugar
  • 2 Tbsp maple syrup
  • 2 Tbsp heavy cream
  • 1 tsp vanilla extract
  • 1 tsp cinnamon
  • 1 tsp salt
  • ½ tsp black pepper

Topping:

  • ½ cup chopped pecans
  • 2 cups marshmallows (about 16 regular size)

Special Equipment Note: You’ll need an oven safe pan such as a casserole dish that fits in your air fryer’s basket or on the rack. I use two small casseroles because I have a Ninja Dual Zone, but one larger dish is fine if you have a single basket model.

Ingredient Tips and Substitutions

  • You can also use canned sweet potatoes in syrup, but I’d omit or at least reduce the brown sugar in this case. Alternatively, swap in freshly cooked, mashed sweet potatoes (about 3 cups)
  • The heavy cream can be swapped for evaporated milk or omitted entirely for a less creamy version
  • I know that mini marshmallows are the classic, but I use the large ones simply because they don’t fly around as easily in the air fryer. If you do use minis, press them into the base so they hopefully stay put. You may also use marshmallow fluff as an alternative!
  • Mix ins: Some optional mix-ins include raisins, dried cranberries, diced pineapple, or additional pecans mixed in with the sweet potatoes. These can offer variation in both texture and flavor!

Step By Step Preparation

Recipe FAQs

Can I Use Canned Sweet Potatoes for the Casserole in the Air Fryer?

Absolutely! Canned sweet potatoes are perfect for sweet potato casserole. Just drain and mash them and they are ready to use.

Alternatively, though, you may use freshly cooked, peeled, and mashed sweet potatoes instead. Canned just saves a lot of preparation time.

What’s the Recommended Seasoning for Air Fryer Sweet Potato Casserole?

Traditionally, sweet potato casserole is seasoned with cinnamon, vanilla, and brown sugar.

However, you can add other spices, such as nutmeg, ginger, or allspice. Maple syrup or honey can add a different flavor element as well. Experiment to find your favorite combination!

Can I Prepare the Casserole Ahead of Time and Air Fry It Later?

Yes, assemble the casserole in advance, refrigerate for up to 24 hours, and air fry when ready to serve.

You can even measure out the topping ingredients ahead of time, but don’t add them to the top of the casserole until the end of the cooking process.

What Temperature and Time Settings Are Ideal for Air Frying Sweet Potato Casserole?

For sweet potato casserole, set your air fryer to 350°F (177°C). Cook for 10-12 minutes until it’s heated through.

Then, add your pecans and marshmallows and toast them, about 3 minutes additionally, for a total of about 15 minutes of cooking time.

How Can I Make the Sweet Potato Casserole in the Air Fryer Dairy Free?

To make your sweet potato casserole dairy free, omit the cream and use a non-dairy butter alternative.

For a vegetarian option, omit the marshmallows and only add pecans to the top. Feel free to toss the pecans in a little additional brown sugar and butter for sweetness and caramelization.

Can I Add Marshmallows to the Sweet Potato Casserole in the Air Fryer?

Yes, you can add marshmallows to sweet potato casserole in the air fryer. However, the mini marshmallows tend to get blown off easily. Use larger size marshmallows, or a coating of marshmallow fluff for better results.

Also make sure to gently push the marshmallow into the sweet potato mixture, which helps to hold it in place.

Is It Possible to Make a Smaller Batch in the Air Fryer?

Yes, one of the great things about air fryer cooking is that it’s ideal for smaller batches. As written, this recipe should give you around 6 servings.

However, it can easily be doubled or halved for larger or smaller batches! Just use a smaller pan for a halved recipe, or cook in two batches if you’re doubling and can’t fit it in your air fryer all at once.

Can I Reheat Leftover Sweet Potato Casserole in the Air Fryer?

Absolutely! Reheat leftover sweet potato casserole at a lower temperature of 325°F for around 5 minutes, or until warmed through. The exact time will depend on the size of your portion.

If the topping starts to overbrown, cover it with a piece of foil.
