Get ready to gather the essentials that make this comforting dish shine!
For the Casserole
- Bacon – Provides a smoky flavor and crunch; reserve 1/4 cup bacon grease for sautéing the vegetables.
- Ground Italian Sausage – Adds a spicy, meaty element; make sure it’s cooked, crumbled, and drained beforehand.
- Russet Potatoes – The starchiness gives structure and heartiness; slice them thin for even cooking.
- White Onion – Contributes sweetness and depth; if you can’t find white onion, any onion variety works in a pinch.
- Garlic Paste – Elevates the flavor profile with rich aromatic notes; fresh garlic can be used as a substitute for an even bolder taste.
- Kale – Enhances nutritional value and color; wash thoroughly and chop well, removing stems for a tender bite.
For the Sauce
- Flour – Aids in thickening the cream sauce, making it luscious and creamy.
- Chicken Broth – Adds essential liquid and depth of flavor; consider low-sodium broth for a healthier option.
- Heavy Whipping Cream – Creates the rich and creamy base; for a lighter dish, half-and-half can be used instead.
- Egg – Acts as a binding agent, enhancing richness; it must be tempered to avoid curdling.

Step‑by‑Step Instructions for Zuppa Toscana Casserole
Step 1: Preheat and Prepare
Begin by preheating your oven to 400°F (204°C). While the oven is heating, take a 9×13” baking dish and spray it generously with non-stick spray to ensure easy removal of your Zuppa Toscana Casserole later. This preparation sets a solid foundation for the layers to come.
Step 2: Layer the Potatoes and Meat
Spread the thinly sliced russet potatoes evenly across the bottom of the prepared baking dish. Next, take the cooked and crumbled Italian sausage along with the crispy bacon, and distribute them evenly over the potato layer. This hearty base is key to capturing all the delicious flavors of the casserole.
Step 3: Sauté the Aromatics
In a large skillet, warm the reserved bacon grease over medium heat. Add the chopped white onions and garlic paste, sautéing them until the onions become translucent and fragrant—approximately 2 to 3 minutes. This process enhances the flavor of the Zuppa Toscana Casserole, providing a wonderful aromatic base for your dish.
Step 4: Cook the Kale
Once the onions are softened, stir in the chopped kale. Cook this mixture until the kale is wilted, which should take about 3-4 minutes. By adding kale at this stage, you incorporate vibrant color and nutrition into your casserole, making it even more comforting and hearty.
Step 5: Create the Cream Sauce
Sprinkle the flour over the kale mixture in the skillet, stirring to combine all ingredients well for about 1 minute. Gradually whisk in the chicken broth, allowing it to simmer until slightly thickened. This will create a creamy sauce that will bind the layers of your Zuppa Toscana Casserole together deliciously.
Step 6: Incorporate the Cream
After your sauce has thickened, pour in the heavy whipping cream, stirring until everything is well combined. The richness of the cream adds depth to your sauce, ensuring that every bite of the casserole bursts with flavor and creamy goodness.
Step 7: Temper the Egg
In a separate bowl, beat an egg and gradually add a bit of the hot sauce to it, whisking constantly to temper it. This prevents the egg from curdling when you mix it back into the sauce. Pour the tempered egg mixture into the sauce, stirring until fully incorporated for an extra layer of richness.
Step 8: Combine Sauce and Cheese
Mix half of the grated Parmesan cheese into the sauce until it melts and combines smoothly. Pour this creamy sauce generously over the layered potatoes and meat, ensuring every ingredient is enveloped in the luscious Zuppa Toscana Casserole sauce.
Step 9: Bake Covered
Cover the dish tightly with aluminum foil and place it in the preheated oven. Bake for 50 to 60 minutes until the potatoes are fork-tender. This step allows the flavors to meld together beautifully while the casserole cooks thoroughly.
Step 10: Add Cheese and Bake Uncovered
After initial baking, carefully remove the foil and sprinkle the remaining Parmesan cheese over the top. Return the casserole to the oven, baking for an additional 25 to 30 minutes until the cheese is bubbly and golden brown. The final layer of cheese adds a delightful texture and richness.
Step 11: Rest Before Serving
Once finished baking, let the Zuppa Toscana Casserole rest for about 10 minutes before serving. This resting period allows the layers to set perfectly, making it easier to slice and serve, enhancing both presentation and enjoyment of the dish.

Expert Tips for Zuppa Toscana Casserole
- Cook Sausage Thoroughly: Ensure the Italian sausage is completely cooked before layering in the casserole. This guarantees food safety and enhances flavor.
- Even Potato Slices: Slice potatoes uniformly for even cooking. Thinner slices cook faster and contribute to a creamy texture throughout the Zuppa Toscana casserole.
- Temper the Egg: Mix a little hot sauce with the beaten egg before adding it to the cream. This prevents curdling and ensures a smooth, rich sauce.
- Bacon Grease Flavor: Don’t skip reserving bacon grease for sautéing. It enhances the flavors of the vegetables, making your casserole even more delicious.
- Rest Before Serving: Allow the casserole to rest for 10 minutes post-baking. This ensures the layers set properly, making it easier to serve and enjoy.
Make Ahead Options
These Zuppa Toscana Casserole preparations are perfect for busy home cooks looking to save time during the week! You can slice the potatoes, cook the Italian sausage and bacon, and sauté the onions and garlic up to 24 hours in advance.

Additionally, the creamy sauce can be made ahead and refrigerated for up to 3 days; just be sure to temper the egg right before mixing it in. When you’re ready to enjoy your casserole, layer everything in the baking dish and bake as directed—just as comforting and delicious as if made fresh!
