POTATO & LEEK GRATIN

Steps:

• Place the broth in a large saucepan along with the seasonings (1 1/2 teaspoons thyme, garlic chips, salt and pepper).
• Trim off the dark green part of the leek. (Use for another purpose.) Take the white-light green portion and split in half lengthwise. Place that in a water bath and rinse well, changing water as needed in order to remove all dirt and sand from the leek. Once clean, slice the leek into thin half discs. Place into the pot of seasoned broth.
• Peel potatoes and slice very thin by hand or by using a mandoline or food processor. Slices should be less than 1/4 inch thick. Place potatoes in the saucepan.
• Preheat oven to 400 degrees.
• Heat contents of the saucepan to a boil over medium-high heat. Reduce flame to a simmer and cook until the potatoes are tooth tender - you can bite'em but they still have some resistance - about 5 minutes.
• Place the contents of the saucepan into 6 individual gratin dishes, ramekins or custard cups. Press down to level the tops. (should your mixture only partially fill the dishes, add a mixture of water and additional broth so that the tops of the contents is within a half inch of the lip of the dish.) Garnish with the remaining thyme.
• Set the dishes on a baking sheet and bake for 30 minutes. Check for potatoes for doneness. Apply a *very* quick application of cooking spray to the tops to aide crispness. Cook an additional 10 minutes or until the potatoes are done and the tops are a crispy golden brown.
• For Vegetarian do not use the Chicken Broth option.

SLOW COOKER POTATO, LEEK, AND KALE GRATIN WITH TOO MUCH CHEESE

Steps:

• Set the slow cooker to the sauté function. Add the oil and, once hot, add the leek and cook for 1-2 minutes, then add the kale and continue cooking for another 2-3 minutes, or until the leek is soft. Gently scoop into a bowl. Line the slow cooker with a sheet of baking paper, working carefully as it will be hot.
• Add the cream, stock and cheeses to a bowl and use a fork to combine.
• Arrange one-third of the potato slices over the bottom of the lined bowl, overlapping them slightly. Pour in one-third of the cream mixture and sprinkle with one-third of the leek mixture. Season and repeat the process until all the ingredients have been used.
• You should get three decent layers of cheesy potato goodness. Close the lid and cook on high for 4 hours.
• Check the liquid at the 3-hour mark. If there is a lot of liquid remaining, leave the lid off for the last hour of cooking. If, at 4 hours, there is still too much liquid, remove the lid and, if your cooker has it, hit the reduce function, or simply the sauté function, and cook for 2-5 minutes. This will quickly get rid of any excess moisture.
• Allow to cool for at least 15 minutes in the slow cooker before gently removing. If you try to cut it when still hot, it tends to go everywhere. Alternatively, scoop the gratin straight from the bowl onto the plate. It might not look amazing, but it's the kind of dish that is here for a good time, not a long time.
• Season generously with salt and pepper and serve. Eat wearing stretchy pants; you are going to need them.
