Units Scale

Meats

  • 8 oz bacon (cooked crisp & crumbled (reserve 1/4 cup bacon grease))
  • 1 lb ground Italian sausage (cooked, crumbled & drained)

Vegetables

  • 7 cups thinly sliced russet potatoes
  • 1 small white onion (peeled & diced)
  • 6 packed cups washed and chopped kale leaves (stems removed)
  • 2 tbsp garlic paste

Dairy & Eggs

  • 11 1/2 cups heavy whipping cream
  • 1 large egg (beaten & tempered)
  • 1 1/2 cups shredded Parmesan cheese (divided)

Pantry

  • 1/2 cup flour
  • 4 cups chicken broth
  • salt & pepper (to taste)

Instructions

  1. Layer Ingredients: Spread the potatoes out in an even layer in the bottom of a 9×13″ baking dish., then spread the sausage and bacon evenly out overtop.
  2. Heat Bacon Grease: Return the bacon grease to the same large skillet you cooked the sausage and bacon in set over medium heat.
  3. Sauté Onions and Kale: Add the onions and garlic, stirring to combine, and saute for 2-3 minutes, just until softened. Add the kale, stirring just until wilted.
  4. Add Flour: Sprinkle the flour out over the skillet, stirring to coat everything, and cook for 60 seconds.
  5. Add Broth and Cream: Add the broth to the skillet and whisk it in, then simmer until slightly thickened. Stir in the cream until evenly incorporated.
  6. Temper Egg: Transfer a a tablespoon of the hot liquid to a small bowl, then add the beaten egg and stir to combine. Stir in another tablespoon of the hot liquid, then one more. Pour the egg mixture back into the skillet, whisking to combine.
  7. Add Cheese: Add half the Parmesan cheese sauce to the skillet, stirring, just until melted and smooth. Pour the sauce mixture evenly out over the potatoes.
  8. Bake Covered and Uncovered: Cover the dish tightly with aluminum foil and bake at 400° for 50-60 minutes. Remove the foil and sprinkle the remaining cheese evenly out overtop. Bake for another 25-30 minutes.
  9. Rest and Serve: Carefully remove the hot dish from the oven and let it rest for 10 minutes so that sauce sets. Serve & enjoy!

Notes

  • Reserve 1/4 cup bacon grease when cooking the bacon for added flavor to the sauce.
  • Be sure to temper the egg slowly with hot liquid to prevent curdling.
  • Letting the casserole rest for 10 minutes allows the sauce to set for easier serving.
