Ingredients For Sweet Potato Casserole with Pecans and Meringue

  • Sweet Potatoes: Peeled and cut into 1 1/2-inch chunks
  • Seasonings: Salt, cinnamon, chipotle powder
  • Orange juice: Preferably freshly squeezed
  • Egg whites: Room temperature. See our tip here.
  • Kitchen Staples: Unsalted butter, sugar, water
  • Maple Syrup
  • Chopped Pecans

How To Make Meringue Topped Sweet Potato Casserole

Step 1: Make Sweet Potato Mash

Place the sweet potatoes in a large saucepan and cover with cold water. Bring the contents to a boil over high heat, and then reduce the heat to maintain a simmer. Cook until the potatoes are tender when pierced with a fork – about 15 to 20 minutes. Drain the water and then return the potatoes to the pot.

Add butter, salt, cinnamon, and chipotle powder. Mash the mixture with a potato masher until no large lumps remain, and then add orange juice and mash until smooth. Cover and keep warm.

Step 2: Prepare the Oven

Position the oven rack in the upper third of the oven and heat the broiler. Coat a broiler-safe 2 ½ quart casserole dish with cooking spray.

Step 3: Make the Meringue

Beat the room temperature egg whites and salt in a stand mixer until soft peaks form. Mix sugar and water in a small saucepan, and then place it over medium-high heat and bring it to a simmer. Swirl the pan gently to dissolve the sugar. Do not slosh the sugar solution on the sides of the pan.

Boil undisturbed until a candy thermometer reaches 238 degrees F. Immediately drizzle the sugar syrup into the egg white mixture while the mixer is still beating continually. Continue beating until the bottom of the bowl is only slightly warm, which should take about 2 minutes longer.

Scoop the meringue into a large resealable bag and set it aside.

Step 4: Make Maple Pecans

In a small saucepan, mix the maple syrup, butter, and pinch of salt. Heat over medium heat until the mixture boils, and then add the pecans and cook while stirring constantly until the nuts are coated. This should take between 1 to 2 minutes.

Step 5: Compile Casserole and Broil

Spread the sweet potato mixture in the prepared casserole dish and then top evenly with the pecans. Cut the corner of the resealable bag off and pipe the meringue decoratively over the sweet potato mixture. Broil, rotating as necessary until the top is browned. This should only take 30 seconds to 2 minutes.

FAQs and Expert Tips

Is making the boiled sugar syrup the same as making caramel?

Essentially, making the boiled sugar syrup is the same technique you would use to make caramel but you’ll just remove it from the heat before it starts to darken.

How do I make sure my sweet potato casserole doesn’t get watery?

Be sure you cut your sweet potatoes into evenly sized chunks so that they’ll cook at the same rate.

Tips for Making Fluffy Meringue Topping

Start with Room Temperature Eggs

Room-temperature eggs are much easier to whip than cold eggs. But you shouldn’t leave your eggs out of the fridge, so there’s a trick to bring the eggs up to room temperature quickly and safely. Simply submerge uncracked eggs into a bowl of hot tap water for several minutes. I do this while I am mise en placing the rest of the ingredients.

How to Beat the Egg Whites

Whip the egg whites in a stand mixer with the whip attachment or in a bowl with a hand mixer until they have formed soft peaks. If you have both a hand mixer and a stand mixer, I recommend the stand mixer because you’ll have an easier time with the next step.

Since the whipped whites don’t have sugar in them (yet) they will not be glossy or stiff, you just want to get them to the soft peak stage. To test if they are soft peaks, remove the beater and dip it into the whites. Hold it upside down and if the whites curl to the side, then you have a nice soft peak. If the peak stands upright it is stiff already.

How to Cook The Egg Whites With Hot Sugar Syrup

  1. As the mixer is running, or as you’re beating (if you have a hand mixer, try to grab a helper for this part) drizzle the hot sugar syrup into the whites. Go slowly, so you don’t deflate the whites. 
  2. You’ll see the whites will become less dry looking and start to get glossy and stiff. The sugar is actually cooking the whites as it is drizzled in. This will stabilize it and make it safe to eat.
  3. Continue beating until the bottom of the bowl is only slightly warm, about 2 minutes longer.
