Hassleback Potato Casserole

Acclaimed food science writer, J. Kenji López-Alt has developed this sort of “mash-up ” ( if you will ) of a classic French gratin, and a beautiful Hassleback potato recipe. The idea is to stand the slices of potato vertically, rather than laying them flat. This ensures each serving receives both a creamy potato serving and a crispy edge in each bite.

This is my adaption.

You’ll Need:

4 to 4 ½ pounds russet potatoes, peeled and sliced 1/8-inch thick slices with a sharp knife of on a mandoline 

4 tablespoons unsalted butter

1 1/2 cups heavy cream

1/2 cup chicken stock

3 medium cloves garlic, minced

1 tablespoon fresh thyme, leaves removed for the stem

Kosher salt and black pepper

1/4 teaspoon ground white pepper

1/2 teaspoon red chili flakes

2 cups finely grated Gruyère cheese

1/2 cup finely grated Parmigiano-Reggiano

1 bunch chives, chopped for garnish

Here’s How:

Adjust oven rack to middle position and heat oven to 400’F degrees. Combine cheeses in a large bowl. Transfer 1/3 of cheese mixture to a separate bowl and set aside for garnish.

Add cream, stock, garlic and thyme to the cheese mixture, and mix well. Season with salt and pepper, add white pepper, and red chili flakes– stir to combine.

Add potato slices and toss with your hands until every slice is coated with cream mixture, making sure to separate any slices that are sticking together to get the cream mixture in between them.

Prepare a 2-quart casserole dish with butter. Place on a high sided baking sheet.

Pick up a handful of potatoes, organizing them into a neat deck stack, lay them in the casserole dish with their edges aligned vertically. Continue placing potatoes in the dish, working around the perimeter and into the center until all the potatoes have been added. The potatoes should be very tightly packed. If necessary, slice an additional potato, coat with cream mixture, and add to casserole. It is important the potatoes are very tight.

Pour the excess cheese mixture evenly over the top of the potatoes in the casserole dish until the mixture comes halfway up the sides. You may not need all the excess liquid.

Cover dish tightly with foil– sprayed on the inside with non-stick cooking spray. Transfer to the oven. Bake for 30-40 minutes. Remove foil and continue baking until the top is golden brown, about 45 minutes longer.

Carefully remove from oven, sprinkle with remaining cheese, and return to oven. Bake until deep golden brown and crisp on top, about 30 minutes longer. Remove from oven, let rest for a few minutes,  garnish with chopped chives and serve.

Enjoy!

Green Beans with Brown Buttered Walnuts and Caramelized Shallots

I love to cook green beans, especially Haricots Verts, pronounced { herəkō ˈver } they are delicious and so tender. They are the French variety typically slimmer and longer than the common green bean we see here in America. You can use any fresh green bean for this recipe. 

You’ll Need:

1- 2 pounds fresh haricots verts, root ends trimmed

4-6 ounces unsalted butter or 3-4 teaspoons good quality olive oil

4-6 gloves of garlic, peeled and smashed

6-8  large shallots, cleaned and sliced thin

1/4-1/2 cup good quality chicken, vegetable stock, or white wine 

Salt and fresh ground pepper 

2 springs fresh thyme

Squeeze of fresh lemon juice 

1 cup browned buttered walnuts, see recipe below 

1 orange zested 

Here’s How

Bring a small saucepan of salted water to a boil. Add the haricots verts and cook until just tender, about 1 minute. Transfer with a slotted spoon to an ice bath. Drain. Pat dry.

In a large skillet, melt the butter over medium-high heat. Add the shallots and sauté until they are browning and nicely caramelized about 5-8 minutes. Add the garlic and continue to cook an additional minute. 

Add the haricots verts and salt and pepper to taste, and cook, stirring, for 3 minutes, or until just heated through and crisp-tender.

Deglaze the pan very quickly with the chicken stock, add the fresh thyme and a squeeze of fresh lemon juice toss. Add toasted walnuts and toss.

Adjust seasoning with salt and pepper one last time, top with orange zest. Serve warm.

Approximately 4-6 serving


Variations: Add cooked bacon bits, panchetta, lemon zest, almonds or a splash of cream 

 

Browned Butter Walnuts


You’ll Need

1 – pound halved fresh walnuts

1 1/2 tablespoons of unsalted butter

1 teaspoon brown sugar

Salt and fresh ground black pepper

In a large sauté over medium heat melt the butter. Add the sliced almonds and sauté storing constantly until golden and fragrant. About 3- 5 minutes toss in the sugar lst minute toss till melted and remove from heat to a sigle layered sheet pan to cool. 

The walnuts will brown fast in the butter so be sure to remove them from the hot pan and cool quickly, or you will risk over browning.

Dust with salt and pepper while warm.
