This recipe comes from Martha Stewart’s Vegetables: Inspired Recipes and Tips for Choosing, Cooking, and Enjoying the Freshest Seasonal Flavors. When they sent me this beautiful cookbook, I knew immediately that Twice-Cooked Potato and Leek Casserole was the one I’d share.
Now that fall is in the air, preparing meals that are comforting and rustic is as natural for me as shopping for mums, decorating the front step with pumpkins, and sipping on warm apple cider.
It’s here – food inspired by the colors of falling leaves.
I love this time of year!
You too?
Buon Appetito!

Description
This delectable Twice-Cooked Potato and Leek Casserole is the perfect combination of sweet and russet potato filling and a crispy leek topping.
Ingredients
2 pounds sweet potatoes, peeled and cut into 1/2-inch pieces
2 pounds russet potatoes, peeled and cut into 1/2-inch pieces
Salt & freshly ground black pepper
3/4 cup whole milk, warmed
3/4 cup heavy cream, warmed
3/4 cup (1 1/2 sticks) unsalted butter, melted
2 Tbsp all-purpose flour
1/8 tsp cayenne pepper
1 leek (white and pale-green parts only), cut into 1/4-inch rings, rinsed well
olive oil or safflower oil, for frying
Instructions
Preheat oven to 425 F.
In two separate saucepans, cover sweet potatoes and russet potatoes each with 1-inch water in two separate saucepans.
Bring to a boil, salt generously, and boil until fork-tender, 8 – 10 minutes; drain.
Return potatoes to respective pans.
In a bowl, combine milk, cream and butter.
Divide milk mixture between saucepans.
Mash both potatoes until smooth; season with salt and black pepper.
Spread mashed sweet potatoes evenly in the bottom of a shallow 2-quart baking dish. Top with mashed russet potatoes; spread evenly to edges.
Bake until golden, about 25 minutes.
Meanwhile, in a bowl, combine flour and cayenne. Add leek; toss to coat.
In a medium saucepan, heat 2-inches oil over medium high until a thermometer registers 350 F.
Working in batches, add leek rings and cook, turning, until crisp and light golden around edges, about 1 minute.
With a slotted spoon, transfer to paper towels to drain.
Season with salt.
Sprinkle fried leeks over potatoes and serve.

Love this easy potato dish, my favorite part are the leeks:) Will definitely make it in the near future. Pinned!
I could crunch those crispy leeks down like nobody’s business! 😉 hahah Thanks, friend!
Wow! I have to say Annie, this is a “Eureka” post for me because just yesterday I made twice baked potatoes with chives. I baked the potatoes, cooled them, scooped them, mashed them, returned mixture to their shells and rebaked…all the while thinking…”there’s got to be an easier way”! Don’t get me wrong I love this process but when you are having a really busy day they take a lot of time…hence, this twice baked casserole! Thanks for this wonderful fall-ish side dish,
Wow! I love that! ‘Eureka’! That’s what we hope for!! Twice baked potatoes are a favorite of mine, which made it easy for me to choose this beauty! So happy you like it, my friend!
These would be absolutely perfect for our Thanksgiving, which is actually about a week away now for us here in Canada! Crazy how it’s almost here. And I just happen to have leeks in my fridge 😉 Delish! Have a wonderful week, my friend 🙂 XOXO
Leeks in your fridge is sign! 🙂 I think you would love this, my friend! XOXO
Make ahead potatoes is such a blessing for holidays and these look fabulous! Loving the leeks for extra flavour.
We can never have too many make ahead recipes! Thank you, friend!
OMG! This looks amazing! Thank you for sharing.
Thank you, Susan!! It’s a keeper! 🙂
