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 the Zuppa Toscana Casserole bakes evenly, creating that perfect golden top. While the oven heats up, you can prepare your baking dish and ingredients, setting the stage for your lovely casserole.
Step 2: Prepare the Potatoes
Grease a 9×13” baking dish with a little cooking spray or butter. Arrange the thinly sliced russet potatoes in a single even layer across the bottom of the dish. Make sure they overlap slightly to ensure even cooking and create a sturdy base for the savory layers to come.
Step 3: Add the Meats
After the potatoes are nestled in the dish, layer the cooked and crumbled Italian sausage evenly over the potatoes. Then, sprinkle the crispy bacon bits on top. This combination adds a smoky, savory flavor to the Zuppa Toscana Casserole that your family will adore.
Step 4: Sauté the Aromatics
In a skillet, heat the reserved bacon grease over medium heat. Add the chopped white onion and garlic paste, sautéing for about 2-3 minutes until the onions are softened and translucent. This helps to bring out their natural sweetness, enhancing the overall flavor of your casserole.
Step 5: Incorporate the Kale
Add the kale to the skillet with the onions and garlic, stirring for about 1 minute until the kale is wilted. This step not only adds vibrant color but also boosts the nutritional value of your Zuppa Toscana Casserole, rounding out the savory layers you’re creating.
Step 6: Thicken the Mixture
Sprinkle flour over the sautéed mixture in the skillet, stirring to ensure everything is coated. Cook for another minute to get rid of the raw flour taste. This thickening agent is crucial for creating that creamy sauce that envelops the layers of your casserole.
Step 7: Add Chicken Broth
Gradually whisk in the chicken broth, stirring continuously until the mixture begins to simmer and thicken slightly, about 2-3 minutes. This rich base brings depth to the Zuppa Toscana Casserole, ensuring every bite is packed with flavor.
Step 8: Stir in the Cream
Once the broth mixture has thickened, reduce the heat to low and stir in the heavy whipping cream until fully combined. You’ll notice the sauce becoming creamy and luscious, perfect for tying everything together in your hearty casserole.
Step 9: Temper the Egg
Take a couple of tablespoons of the hot sauce and slowly whisk them into the beaten egg. This step, known as tempering, prevents the egg from scrambling. After it’s tempered, whisk the egg mixture back into the skillet, adding richness and helping to set the sauce in the oven.
Step 10: Add Parmesan Cheese
Mix in half of the grated Parmesan cheese to the sauce, stirring until it’s melted and smooth. This cheesy goodness not only enhances the flavor but also adds significant creaminess to your Zuppa Toscana Casserole.
Step 11: Assemble the Casserole
Pour the creamy sauce evenly over the layered potatoes, sausage, and bacon in your baking dish. Use a spatula to ensure all layers are coated for maximum flavor. This step creates a delightful blend of textures and tastes that everyone will love.
Step 12: Bake the Casserole
Cover the baking dish with foil and bake in the preheated oven for 50-60 minutes. Once the baking time is up, carefully remove the foil, sprinkle the remaining cheese on top, and return it to the oven. Bake uncovered for an additional 25-30 minutes until golden and bubbly.
Step 13: Rest Before Serving
After baking, let your Zuppa Toscana Casserole rest for about 10 minutes. This resting period allows the layers to set, ensuring every slice holds together beautifully. Serve warm, and watch as it warms the hearts of everyone at your table.

Zuppa Toscana Casserole Recipe FAQs
How do I choose the best potatoes for my Zuppa Toscana Casserole?
For this recipe, I recommend using russet potatoes because they provide the heartiness and texture that form the base of the casserole. Look for firm potatoes with smooth skin and no dark spots or blemishes. If you prefer a sweeter flavor profile, you can also use sweet potatoes.
How should I store leftovers of my Zuppa Toscana Casserole?
Absolutely! To store leftovers, place them in an airtight container and keep them in the fridge for up to 4 days. It’s best to let the casserole cool down to room temperature before sealing it to prevent condensation, which can make the dish watery.
Can I freeze my Zuppa Toscana Casserole?
Yes, you can freeze it! I often freeze it before baking so that it stays fresh. Wrap the unbaked casserole tightly in plastic wrap and aluminum foil, and it will be good for up to 3 months. When you’re ready to enjoy it, thaw overnight in the fridge, then bake as instructed.
What should I do if my casserole turns out too watery?
If your Zuppa Toscana Casserole ends up being watery, it might be because of excess liquid from the ingredients, particularly if the kale was not wilted enough or too much broth was added. To remedy this, you can bake it a bit longer uncovered to allow excess moisture to evaporate. You could also add a bit more flour during the preparation to thicken the sauce further.
Are there any dietary considerations I should be aware of?
When preparing the Zuppa Toscana Casserole, make sure to check for allergies among your loved ones, especially since it contains ingredients like heavy cream, cheese, and sausage. If you’re cooking for someone with dairy allergies, you can substitute the cream with coconut milk or a dairy-free alternative. Additionally, for a lighter meal, consider using ground turkey instead of sausage.
