Twice Baked Sweet Potato Soufflés

So I haven’t been on here for quite some time. I’d like to say it’s because I’ve been busy traveling the world, learning new languages and meeting interesting people. The truth is, I’ve just been enjoying my cozy life in Huntington Beach. I suppose I have done a bit of traveling – I braved a tropical storm in Turks and Caicos, attended the Consumer Electronics Show for work in Las Vegas and even made it up to San Francisco a couple times. Oh, and I did attempt to learn Mandarin with Rosetta Stone for about five minutes one Saturday before I decided my time would be better spent alphabetizing my bookshelves (no, really). But for the most part, nothing has changed.

All that to say, it took a really really amazing recipe to pull me out of my posting slump. And this is it.

Last weekend, I visited my parents in San Diego and my mom whipped up a batch of twice baked sweet potato soufflés. These. Things. Are. Delicious.  And they’re so dang cute! They’re my new favorite thing. And I’m not just talking about food. If you have any sense at all, you’ll make them and taste for yourself. Here’s how.

SweetPotatoSouffle02(Obligatory family shot.)

SweetPotatoSouffle03The first step is to roast the gahhhlic. Just cut the tops off of three bulbs, sit them on a piece of tin foil and drizzle them with olive oil. Add some water to the foil packet, seal it up and pop it in the oven until the garlic looks like this.

SweetPotatoSouffle04While you’re at it, roast some olive-oil drizzled sweet potato cubes in the same oven until tender.

SweetPotatoSouffle05Once the sweet potatoes and garlic are ready, squeeze the garlic out of each clove and puree it all (every last drop!) with the sweet potatoes and plenty of salt and pepper in a food processor. Resist the urge to dive face first into the food processor. It only gets better from here.

SweetPotatoSouffle06In a saucepan, melt butter over low heat. Add flour and continue to stir over low heat for 2 minutes until the butter and flour come together. It’s important to stick at it for this long to cook the starchy taste out of the roux. No one likes a starchy roux.

SweetPotatoSouffle07Now, slowly add in the milk and stir continuously until the mixture is almost boiling. It should be quite thick. Then, add half of the cheese to the mixture and stir over low heat until melted.

SweetPotatoSouffle08Remove the mixture from the heat, add in the sweet potato and garlic puree and, once it has cooled down, mix in the egg yolks and season.

SweetPotatoSouffle09In a separate bowl beat egg whites until they form medium peaks then fold the egg whites into the sweet potato mixture in two batches. Be gentle with it. Show it some love. The goal is to keep as much air in the mixture as possible.

SweetPotatoSouffle10You’re almost done! Divide the mixture into 6 buttered ramekins, place said ramekins in a roasting pan and fill the roasting pan with enough water to come 1/3 of the way up the sides of the ramekins. Bake for 25 to 30 minutes, or until they’re set and look …

SweetPotatoSouffle11… like this. Now, allow them to cool completely. It’s ok if they fall. They’re supposed to. These soufflés aren’t the high maintenance, fussy type. They’re the down-to-earth, doesn’t-matter-if-they-sink type.

SweetPotatoSouffle12Last step! Just before you’re ready to serve the soufflés, turn them out onto individual oven-safe dishes, cover completely with cream and the remaining cheese and return to a 425 degree oven for ten minutes …

SweetPotatoSouffle13… until they look like this. And garnish them …

SweetPotatoSouffle14… until they look like this. For your convenience, here’s the recipe, adapted especially for you, from Sainsbury’s Magazine. It was a lot of math. Grams to ounces, Celsius to Fahrenheit … you’re welcome.


  • 3 heads garlic, tops removed
  • 3 tbsp olive oil
