Ingredients

• 1 (16 ounce) package frozen pierogies
• 1 tablespoon olive oil
• 1 pound pork loin, cut into 1/2 inch cubes
• 1 (10.75 ounce) can condensed cream of mushroom soup
• 1 cup sour cream
• 3/4 cup milk
• 1 (15.25 ounce) can whole kernel corn, drained
• 1/2 cup diced onion
• 1/2 teaspoon chopped fresh rosemary
• 1/4 teaspoon ground black pepper
• 1/2 cup Cheddar cheese, shredded

Instructions

1. Preheat an oven to 350 degrees F (175 degrees C).
2. Bring a large pot with lightly salted water and to a rolling boil. Stir in the frozen pierogies and return to a boil. Cook uncovered, stirring occasionally, until the pierogies float to the top and the filling is hot, 5 to 7 minutes. Drain.
3. Heat the olive oil in a skillet over medium-high heat. Add the pork and cook, stirring occasionally, until the pork is no longer pink in the center, about 5 minutes. Transfer the pork to a large mixing bowl along with the cooked pierogies. Add the cream of mushroom soup, sour cream, milk, corn, and onion. Season with rosemary and pepper; stir. Pour into a 2-quart casserole dish and sprinkle with Cheddar cheese.
4. Bake in the preheated oven until the cheese has browned and the casserole is heated through, about 30 minutes.
