4 Tablespoons butter (plus a bit more to rub on a parchment-lined baking sheet)
2 Tablespoons beef bacon drippings
1 teaspoon sea salt
1/2 teaspoon freshly ground black pepper
2 pounds Harvest Haven Butterball potatoes, unpeeled
1 small Harvest Haven onion
extra equipment: outer ring of 9 inch spring form cake pan
Preheat oven to 425.
Melt bacon drippings and 2 tablespoons of butter. Place in a large bowl with salt, and pepper.
Slice potatoes (using a mandolin if you've got one) into 1/8 inch thick rounds. Toss them with the butter and seasonings in the large bowl until well coated in yumminess.
Peel and thinly slice onion and toss in a smaller bowl with 1 tablespoon melted butter.
Cover a baking sheet with a layer of parchment. Place the springform on top of the parchment. Brush the parchment with a little melted butter to avoid sticking.
Take 1/4 of the sliced potatoes and arrange them within the springform ring. Then add a layer of onion. Continue layering a couple more times until all the potatoes and onions are layered up. Please, make sure to have a potato layer on top. Carefully remove ring.
Place the baking sheet on the middle rack of your preheated oven. Bake for 40-45 minutes until potatoes are tender, then brush the top of the galette with one last tablespoon of melted butter. Put back in the oven for another 5-10 minutes. Edges of potatoes should be crisp and the whole galette should be a nice golden brown.
Season with a sprinkling of additional salt if desired. Slice and serve.
