Zuppa Toscana Casserole Recipe
Introduction
Zuppa Toscana Casserole is a comforting and hearty dish inspired by the beloved Italian soup. Layers of crispy bacon, savory sausage, tender potatoes, and creamy kale sauce make this casserole perfect for family dinners or cozy gatherings.

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 – 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 thinly sliced potatoes evenly in the bottom of a 9×13″ baking dish. Layer the cooked sausage and crumbled bacon evenly over the potatoes.
- Step 2: Return the reserved bacon grease to the large skillet you used for cooking the sausage and bacon. Heat over medium heat.
- Step 3: Add the diced onion and garlic paste to the skillet. Sauté for 2-3 minutes, stirring occasionally, until the onions soften. Add the chopped kale and stir just until it wilts.
- Step 4: Sprinkle the flour evenly over the skillet contents and stir to coat. Cook for about 60 seconds to remove the raw flour taste.
- Step 5: Slowly whisk in the chicken broth, then bring to a simmer. Cook until the sauce thickens slightly. Stir in the heavy cream until well combined.
- Step 6: Transfer about one tablespoon of the hot sauce to a small bowl. Stir in the beaten egg to temper it, then gradually add two more tablespoons of hot sauce, stirring constantly. Pour the egg mixture back into the skillet and whisk thoroughly to combine.
- Step 7: Add half of the Parmesan cheese to the skillet and stir until melted and smooth. Pour this sauce evenly over the layers in the baking dish.
- Step 8: Cover the dish tightly with aluminum foil and bake in a preheated 400°F oven for 50–60 minutes. Remove the foil, sprinkle the remaining Parmesan cheese over the top, and 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 a spicier kick, use hot Italian sausage or add red pepper flakes to the sauce.
- Swap kale with spinach or Swiss chard for a different leafy green flavor.
- If preferred, use half-and-half instead of heavy cream for a lighter sauce.
- To save time, cook the sausage and bacon the night before and refrigerate until ready to assemble.
Storage
Store leftover casserole covered in the refrigerator for up to 3 days. Reheat individual portions in the microwave or warm the entire dish in a 350°F oven until heated through. The casserole may thicken after refrigeration; add a splash of chicken broth or cream when reheating if needed to loosen the sauce.
