Step‑by‑Step Instructions for Zuppa Toscana Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C) to ensure it’s hot and ready for baking your comforting Zuppa Toscana Casserole. This high heat will help achieve a beautifully crispy top layer while keeping the inside creamy and hearty. Prepare a 9×13” baking dish by greasing it lightly with cooking spray or olive oil.
Step 2: Prepare the Potatoes
Slice your russet potatoes thinly, aiming for even pieces to ensure uniform cooking. Layer the potato slices in the greased baking dish, spreading them out to create an even base. This hearty layer will absorb the flavors of the casserole and form a satisfying foundation for the delicious toppings to come.
Step 3: Cook the Meats
In a skillet over medium heat, cook the ground Italian sausage until fully browned and crumbly, about 5-7 minutes. You’ll want it to sizzle and be golden brown. Add the cooked sausage evenly over the potatoes, then crumble crispy bacon on top. This combination provides a smoky flavor that perfectly complements the creamy base.
Step 4: Sauté Onion and Garlic
In the same skillet, using the reserved bacon grease, sauté the diced onion and garlic paste over medium heat until softened, about 2-3 minutes. Stir occasionally, watching for the onions to turn translucent and fragrant. This aromatic blend enhances the flavor profile of your Zuppa Toscana Casserole beautifully.
Step 5: Add the Greens
Next, stir in the kale leaves, cooking until they wilt down, about 2-3 minutes. This adds a nutritious touch and brings vibrant color to your casserole. Once wilted, sprinkle the flour into the mixture, stirring well to coat the greens and create a roux that will help thicken your sauce.
Step 6: Make the Sauce
Gradually whisk in the chicken broth, allowing it to simmer for 3-5 minutes until the mixture thickens slightly. Watch for bubbling around the edges, which indicates the sauce is coming together. This step is crucial for achieving the perfect creamy consistency that makes the Zuppa Toscana Casserole irresistible.
Step 7: Incorporate Cream and Egg
Stir in the heavy whipping cream, bringing everything to a gentle simmer. Temper the beaten egg by gradually adding a spoonful of the hot mixture into it, then stir this back into the sauce. This method prevents curdling and ensures a rich, silky texture throughout your casserole.
Step 8: Add Cheese
Mix in half of the shredded Parmesan cheese, stirring until it melts and combines into the creamy sauce. This add-in will elevate the dish, giving it depth and that cheesy goodness everyone loves in a casserole. Make sure to taste and adjust seasoning if necessary!
Step 9: Combine and Bake
Pour the creamy sauce over the layered potatoes, making sure to cover them evenly. Then, cover the dish tightly with aluminum foil to retain moisture. Bake in the preheated oven for 50-60 minutes. You’ll know it’s ready when the potatoes are fork-tender and the casserole is bubbling around the edges.
Step 10: Add More Cheese
After baking, carefully remove the foil and sprinkle the remaining Parmesan cheese on top. Return the dish to the oven and bake uncovered for an additional 25-30 minutes, or until the cheese is golden brown and crispy. This glorious topping adds that final touch of indulgence to your Zuppa Toscana Casserole.
Step 11: Final Touch
Once baked, remove the casserole from the oven and allow it to rest for about 10 minutes before serving. This resting time helps the casserole set correctly and makes it easier to cut into portions. The result will be a beautifully layered comfort dish, perfect for a cozy family meal.

Storage Tips for Zuppa Toscana Casserole

Freezer: You can freeze the casserole for up to 3 months. Be sure to wrap it tightly in plastic wrap and aluminum foil to protect against freezer burn.
Reheating: For best results, reheat in the oven at 350°F (175°C) until warmed through, about 20-25 minutes. You can also use a microwave, but oven reheating maintains the crispy top.
