Pierogi Lasagna Adapted from https://www.allrecipes.com/my-moms-5-ingredient-pierogi-lasagna-7557704 5-Ingredient Casserole Is Always the First Thing Gone at a Potluck I made this. Servings: 6 INGREDIENTS 8 ounces lasagna noodles, cooked 6 servings instant mashed potatoes 1 cup shredded Cheddar cheese, divided Black pepper ¼ cup butter 1 large onion, diced STEPS 1) Preheat oven to 350 degrees F. Grease a 9x13-inch baking dish. 2) Cook the noodles, cool rinse and set aside. 3) While the noodles cook, melt the butter in a frying pan over medium heat. Add onion and sauté, stirring occassionally, until translucent. 4) Cook instant mashed potatoes according to package instructions. Mix in half the shredded Cheddar cheese and season with black pepper, to taste. 5) Place half of the lasagna noodles in a single layer in the prepared pan, then top with half of the onions, followed by the mashed potatoes. Top the potatoes with the rest of the lasagna noodles, then top the noodles with the remaining cheese and onions. 6) Bake until heated through and the cheese is melted, about 20 minutes. NOTES Dale 2023-Reduced butter Looks like a double batch would fit in the pan.
