Step‑by‑Step Instructions for Zuppa Toscana Casserole

Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). This ensures that once your casserole is assembled, it will cook evenly and thoroughly. While the oven heats, gather your 9×13 baking dish and prepare the ingredients for layering.

Step 2: Layer the Potatoes
Grease the bottom of the baking dish with a bit of cooking spray or leftover bacon grease. Layer the thinly sliced russet potatoes evenly across the bottom, creating a solid foundation for your Zuppa Toscana Casserole. Aim for uniform slices, so they cook through at the same rate, about 1/8 inch thick.

Step 3: Add the Meat
Crumble the cooked Italian sausage and spread it evenly over the potato layer, followed by the crispy bacon pieces. This mixture of savory meats adds depth and flavor while contributing to the heartiness of the casserole. Ensure the meat is evenly distributed for consistent taste in every bite.

Step 4: Sauté the Aromatics
In a skillet, heat the reserved bacon grease over medium heat. Add diced white onions and garlic paste, sautéing until the onions are translucent and fragrant, about 2-3 minutes. This step builds a comforting base of flavor that enhances the entire Zuppa Toscana Casserole.

Step 5: Incorporate the Greens
Next, add chopped kale to the skillet with the sautéed onions and garlic. Cook just until the kale is wilted, stirring occasionally for about 1-2 minutes. This keeps the greens vibrant and tender, maximizing their nutritional benefits while adding a delightful color to the dish.

Step 6: Create the Sauce
Stir in flour into the skillet, cooking for roughly 1 minute until it’s lightly browned. Gradually pour in chicken broth while stirring continuously to avoid lumps, and let it simmer until the sauce thickens, about 3-4 minutes. This rich sauce binds all elements of the Zuppa Toscana Casserole together.

Step 7: Mix in the Cream
Incorporate the heavy whipping cream and whisk until integrated. Carefully temper the beaten egg by slowly mixing in a few spoonfuls of the hot sauce to bring it to temperature before adding it back to the skillet. Stir in half of the grated Parmesan cheese for an added layer of creaminess.

Step 8: Assemble the Casserole
Pour this delicious sauce evenly over the layered potatoes and meat in the baking dish, ensuring every component is generously coated. This will be the heart of your Zuppa Toscana Casserole, bringing together all the rich flavors and creamy texture.

Step 9: Bake the Casserole
Cover the baking dish with aluminum foil and place it in the oven. Bake for 50-60 minutes, allowing the casserole to cook thoroughly and the flavors to meld. When the time is up, remove the foil to expose the top, creating a nice golden finish.

Step 10: Add the Final Touches
Sprinkle the remaining Parmesan cheese over the casserole and return it to the oven. Bake uncovered for an additional 25-30 minutes, or until the cheese is bubbly and golden brown. This creates a beautiful crust that adds texture to your hearty Zuppa Toscana Casserole.

Step 11: Cool and Serve
Once baked, remove the casserole from the oven and let it rest for about 10 minutes. This rest time allows the sauce to set, making it easier to serve. Now you’re ready to enjoy your scrumptious, warm Zuppa Toscana Casserole with family and friends!
