Ingredients
- 8 oz bacon, cooked crisp and crumbled (reserve 1/4 cup bacon grease)
- 1 lb ground Italian sausage, cooked, crumbled, and drained
- 7 cups thinly sliced russet potatoes
- 1 small white onion, peeled and diced
- 2 tbsp garlic paste
- 6 packed cups washed and chopped kale leaves (stems removed)
- 1/2 cup flour
- 4 cups chicken broth
- 1 to 1 1/2 cups heavy whipping cream
- 1 large egg, beaten and tempered
- Salt and pepper to taste
- 1 1/2 cups shredded Parmesan cheese, divided
Instructions
- Step 1: Spread the sliced potatoes evenly in the bottom of a 9×13″ baking dish. Then, spread the cooked sausage and crumbled bacon evenly over the potatoes.
- Step 2: Return the reserved bacon grease to the large skillet used to cook the sausage and bacon, and heat over medium.
- Step 3: Add the diced onions and garlic paste to the skillet, stirring to combine. Sauté for 2–3 minutes, until onions are softened. Add the kale and stir just until wilted.
- Step 4: Sprinkle the flour over the skillet contents, stirring to coat everything evenly. Cook for 60 seconds to remove the raw flour taste.
- Step 5: Slowly add the chicken broth while whisking to prevent lumps. Simmer the mixture until it thickens slightly, then stir in the heavy cream until smoothly incorporated.
- Step 6: Transfer one tablespoon of the hot liquid to a small bowl. Whisk in the beaten egg to temper it. Gradually add two more tablespoons of hot liquid to the bowl, stirring well each time. Pour this egg mixture back into the skillet, whisking constantly to combine.
- Step 7: Stir half of the shredded Parmesan cheese into the skillet until melted and smooth. Pour the sauce evenly over the potatoes, sausage, and bacon in the baking dish.
- Step 8: Cover the dish tightly with aluminum foil and bake at 400°F (200°C) for 50–60 minutes. Remove the foil and sprinkle the remaining Parmesan cheese evenly over the top. Bake uncovered for an additional 25–30 minutes.
- Step 9: Carefully remove the casserole from the oven and let it rest for 10 minutes to allow the sauce to set. Serve warm and enjoy!
Tips & Variations
- For extra creaminess, use full-fat heavy cream and don’t skimp on the cheese.
- If you prefer less spicy sausage, choose mild Italian sausage or substitute with turkey sausage.
- Use fresh garlic instead of garlic paste for a more robust flavor.
- Swap kale for spinach or Swiss chard if you want a different leafy green.
Storage
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven at 350°F (175°C) until warmed through, or microwave in short bursts to avoid curdling the cream sauce. This casserole does not freeze well due to the cream and potatoes.
