Melt the remaining ½ a stick of butter in a large skillet over medium heat. Cook the shallots for a few minutes until they have softened. Add the pierogies in batches and cook until browned on both sides. Serve the Keto Pierogies with onions on top and a side of sour cream.
Place pierogi in boiling water in batches. They will sink to the bottom of the pot and then rise to the top. Once they rise, let them cook for about a minute more. Meanwhile, drizzle platter with remaining 8 tablespoons melted butter. Remove pierogi from pot, and transfer to platter to prevent sticking. Serve immediately. Soooooooooo delicious!!!!!
The Pierogie. They are usually filled with potatoes and cheese, but I've seen sauerkraut pierogies, onion pierogies, and even sweet cheese pierogies. They are so popular in Pittsburgh that they have their own section in the supermarket. The pierogi section actually shows up in a Pittsburgh Dad video (below).
