This casserole is the next best thing to real pierogi when time is a consideration. It's a meatless, layered affair that uses lasagna noodles in place of pierogi dough and cottage cheese in place of farmer's cheese. The dish comes together in a snap especially if you use oven-ready lasagna noodles. It's a great brunch/buffet offering that can be made ahead.

Ingredients

  • 1 package oven-ready lasagna noodles (8 ounces, or 12 noodles)
  • 3 medium potatoes (peeled and cut into large chunks or 2 cups prepared instant mashed potatoes)
  • 2 cups cottage cheese (small curd)
  • 1 large egg (beaten)
  • 1/2 teaspoon onion salt (divided)
  • 1 cup Cheddar cheese (shredded)
  • 1/4 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1 cup caramelized onions
  • 1/2 cup breadcrumbs (dry)
  • Garnish: sour cream

Steps to Make It

Glass Bakeware Warning

For premade casseroles or leftovers that are in a glass baking dish and have been refrigerated, do not place directly into a hot oven as the glass can shatter. Instead, place any cold glass bakeware into a cold oven to warm up while it preheats. Or, allow the bakeware to rest outside of the fridge for 30 minutes to reach room temperature while the oven preheats.

Make Ahead: Prepare recipe as directed. Do not bake. Cover with plastic wrap, then foil. Refrigerate up to 24 hours or freeze up to 2 months. When ready to bake, remove plastic wrap and replace foil. Bake refrigerated casserole about 40 minutes and frozen casserole about 1 1/2 hours.
