Zuppa Toscana Casserole Ingredients For the Casserole Base • Bacon – Adds smoky flavor and crunch; reserve 1/4 cup bacon grease for cooking. • Ground Italian Sausage – Provides a savory meaty base—cook until crumbled and drained. • Russet Potatoes – Serves as the hearty component to create layers—7 cups thinly sliced. • White Onion – Adds sweetness and depth; if unavailable, any onion can be used. • Garlic Paste – Enhances flavor—2 tablespoons. • Kale Leaves – Adds nutrition and color; use 6 packed cups, washed and chopped. For the Creamy Sauce • Flour – Acts as a thickening agent in the sauce—1/2 cup. • Chicken Broth – Creates the liquid base for the sauce—4 cups. • Heavy Whipping Cream – Brings richness to the dish—1 to 1.5 cups. • Egg – Helps to temper the sauce and add richness—1 large, beaten. For the Topping • Parmesan Cheese – Adds creaminess and flavor—1.5 cups, divided. • Salt & Pepper – Enhances the overall taste to preference. Step‑by‑Step Instructions for Zuppa Toscana Casserole Step 1: Preheat and Prepare Preheat your oven to 400°F (200°C) and lightly spray a 9×13″ baking dish with nonstick spray. This preparation ensures that the Zuppa Toscana Casserole comes out perfectly without sticking. Set the dish aside so that it’s ready for layering the ingredients. Step 2: Layer the Potatoes Spread the thinly sliced russet potatoes evenly across the bottom of the prepared baking dish, creating a solid foundation for your casserole. Make sure each slice overlaps slightly to cover the surface fully. This layer will soak up the flavors from the sausage and cream as it bakes, enhancing the overall taste. Step 3: Add the Meats Next, sprinkle the crumbled cooked Italian sausage and crispy bacon evenly on top of the potato layer. This combination of meats adds a savory depth that is essential to the Zuppa Toscana Casserole. The fats from the sausage and bacon will enrich the dish as it bakes, ensuring each bite is flavorful. Step 4: Sauté Onions and Garlic In a skillet, heat the reserved 1/4 cup of bacon grease over medium heat. Once hot, add the chopped white onion and garlic paste, sautéing for 2-3 minutes until the onions become translucent and fragrant. This step builds the aromatic base for your casserole, infusing it with delicious flavor. Step 5: Cook the Kale Stir in the chopped kale into the skillet with the sautéed onions and garlic. Cook for about 3-4 minutes, or until the kale has wilted and brightened in color. This addition not only brings nutrition to the Zuppa Toscana Casserole but also a vibrant pop of green that enhances its visual appeal. Step 6: Make the Creamy Sauce Sprinkle in the flour and stir for 1 minute to coat the mixture, ensuring the flour is fully incorporated. Gradually whisk in the chicken broth and let it simmer for about 5 minutes, or until the sauce thickens and bubbles form. This creamy base is crucial for binding the layers together. Step 7: Add Cream Once the sauce has thickened, remove it from the heat and mix in the heavy whipping cream until fully combined. The cream adds richness to the Zuppa Toscana Casserole that melds beautifully with the other ingredients. The sauce should have a velvety texture and a creamy consistency. Step 8: Temper the Egg In a separate bowl, gradually mix in a small amount of the hot sauce into the beaten egg to temper it. This will prevent the egg from scrambling when added to the hot mixture. Then, blend the tempered egg back into the skillet, enhancing the richness of the sauce. Step 9: Combine with Cheese Stir in half of the grated Parmesan cheese into the sauce until melted and evenly distributed. This adds a cheesy goodness to the creamy mixture. Pour this cheese-laden sauce over the layered potatoes, sausage, and bacon, ensuring an even distribution across the entire surface. Step 10: Bake the Casserole Cover the baking dish tightly with aluminum foil and bake in the preheated oven for 50-60 minutes. After baking, carefully remove the foil, sprinkle the remaining Parmesan cheese on top, and return it to the oven for an additional 25-30 minutes, or until golden and bubbly. Step 11: Let It Rest Once baked, remove the Zuppa Toscana Casserole from the oven and allow it to rest for 10 minutes. This resting period is vital as it allows the sauce to set slightly, making for cleaner slices and easier serving. The inviting aroma will surely tempt everyone! Zuppa Toscana Casserole Variations Feel free to get creative and customize your Zuppa Toscana Casserole with these delightful twists that will elevate your dish! Sweet Potatoes: Substitute russet potatoes for sweet potatoes for a naturally sweeter flavor. This twist adds a hint of warmth and a lovely color contrast. Spinach Alternative: If kale isn’t available, swap it out for fresh spinach. It wilts quickly and offers a milder flavor, perfect for those who prefer a lighter green. Dairy-Free Delight: For a dairy-free version, replace heavy cream with a full-fat coconut milk or almond milk alternative. It provides a creamy texture and a hint of sweetness. Add Some Heat: Spice things up by adding red pepper flakes or sliced jalapeños for a kick of heat. A touch of warmth can enhance flavor and turn up the excitement level. Extra Veggies: Incorporate additional veggies like zucchini or bell peppers mixed into the layers for added nutrition and colorful variety. These can bring fresh flavors and beautiful hues to your casserole. Cheesy Boost: Mix in some mozzarella for extra creaminess and flavor. It melts beautifully, creating a deliciously gooey topping that’s hard to resist. Herbs and Spices: Enhance the flavor by adding dried oregano or thyme to the sausage mixture. These aromatic herbs will elevate the taste by adding depth and warmth. Vegan Twist: For a vegan adaptation, use lentils or chickpeas in place of the sausage and find a suitable plant-based cream. This version is full of protein and still deliciously hearty, perfect for plant-based eaters! Whether you’re experimenting with flavors or dietary needs, there are so many ways to make this Zuppa Toscana Casserole your own. Happy cooking! Make Ahead Options These Zuppa Toscana Casserole preparations are a game-changer for busy weeknights! You can slice the potatoes, cook the sausage, and crumble the bacon up to 24 hours in advance. Store them separately in airtight containers in the fridge to maintain freshness. Additionally, you can prepare the creamy sauce (up to 3 days ahead) by completing steps through mixing in the heavy cream and tempering the egg; just refrigerate it tightly covered. When you’re ready to serve, layer your ingredients in the baking dish, top with the sauce, and follow the baking instructions. This method not only saves time but ensures your casserole is just as delicious when it comes time to enjoy it! Expert Tips for Zuppa Toscana Casserole • Prep Ahead: Make and layer the ingredients a day before baking for an easier mealtime experience.

If your Zuppa Toscana Casserole ends up a little watery, it may be due to excess moisture from the cooked meats or kale. To avoid this, make sure to drain any liquid before layering the ingredients.
