(tweaked from The Upper Crust)
baked in an 8” cast iron skillet, six generous servings
1 medium onion, peeled, thinly sliced
1 tablespoon butter
2 sweet potatoes, (about 12 oz. total weight) peeled and shredded to equal 4 cups
½ cup shredded sharp cheddar cheese
1 cup white whole wheat flour
1 teaspoon baking powder
1 teaspoon salt
⅛ teaspoon cayenne pepper
⅛ teaspoon hot paprika
1 teaspoon finely chopped fresh parsley
1 teaspoon finely chopped fresh thyme
1 large egg
1½ cups whole milk
2 teaspoons olive oil for the skillet
Adjust the oven racks to accommodate the cast iron skillet on the bottom and middle racks. Preheat the oven to 375 degrees. In a small sauté pan, melt the butter. Add the sliced onion and cook over low heat until caramelized. Set aside to cool. In a medium bowl, whisk together the flour, baking powder, salt, cayenne, paprika and fresh herbs. In a large bowl, toss together the shredded sweet potatoes, cheese, cooled onions and the dry ingredients. In a small bowl, whisk together the egg and milk and pour this over the potatoes/cheese/onions/dry ingredients. Use a rubber spatula to combine the mixture.
Heat the olive oil in the cast iron skillet until it sizzles, then add the potato mixture to the pan, smoothing the top with an offset spatula. Using oven mitts, set the skillet on a baking sheet and place on the bottom rack of the preheated oven. After 20 minutes, move the baking sheet with the skillet to the middle rack and continue baking for an additional 20-25 minutes. The potatoes should be golden and slightly crispy around the edges; total baking time is about 45 minutes.
Serve with a generous dollop of sour cream and blueberry filling / topping.
