Step‑by‑Step Instructions for Zuppa Toscana Casserole

Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). This will ensure a perfectly baked Zuppa Toscana Casserole, where all flavors meld beautifully. While the oven warms up, gather all your ingredients to streamline the cooking process, making it a breeze to layer your casserole once the oven is ready.

Step 2: Layer the Potatoes
In a 9×13″ baking dish, start by evenly layering the thinly sliced russet potatoes to create a sturdy base. Take your time to spread them out, ensuring they cover the bottom completely. This layering is key to providing that hearty foundation for the comforting flavors of the Italian sausage and bacon to come.

Step 3: Add the Meat
Next, spread the cooked and crumbled Italian sausage and crispy bacon over the potato layer. Make sure to distribute the meat evenly, so every bite of your Zuppa Toscana Casserole has a delicious bite of both sausage and bacon. This mix enhances the savory profile, creating a mouthwatering experience.

Step 4: Sauté the Aromatics
In the skillet with the reserved bacon grease, add the diced white onion and garlic paste. Sauté this mixture over medium heat for 2-3 minutes, stirring occasionally, until the onions are softened and translucent. The aroma will fill your kitchen, signaling the deliciousness that is about to unfold in your casserole.

Step 5: Cook the Kale
Add the chopped kale to the skillet, stirring until it wilts down, which should take another 2-3 minutes. This adds both nutrition and a vibrant color to your Zuppa Toscana Casserole. Then, sprinkle in the flour, mixing it with the wilted kale for about a minute to create a flavorful base for the creamy sauce.

Step 6: Prepare the Cream Sauce
Gradually whisk in the chicken broth to the skillet, allowing it to simmer while stirring occasionally. Cook this mixture until slightly thickened, about 3-5 minutes. Next, stir in the heavy whipping cream, transforming it into a rich, creamy sauce that will bind all the ingredients together in your delightful casserole.

Step 7: Temper the Egg
To stabilize the sauce, temper the beaten egg by gradually mixing a small amount of the hot cream mixture into it, whisking continuously. Then, slowly pour this tempered egg mixture back into the skillet, stirring well. This step ensures a velvety texture for your Zuppa Toscana Casserole without any scrambled bits.

Step 8: Combine and Pour
Mix in half of the Parmesan cheese into the skillet, stirring until melted and smooth. Then, pour this creamy concoction evenly over the layered potatoes, sausage, and bacon, ensuring every layer is covered. This cheese sauce is the secret to that golden, bubbly top you’re aiming for.

Step 9: Bake the Casserole
Cover the baking dish tightly with aluminum foil and place it in the preheated oven. Bake for 50-60 minutes, allowing the flavors to meld and the potatoes to soften. You’ll know it’s ready when the edges begin to bubble, and the smell fills your kitchen with mouthwatering aromas.

Step 10: Add Cheese and Finish Baking
After the initial baking time, carefully remove the foil and sprinkle the remaining Parmesan cheese over the top of the casserole. Return it to the oven and bake uncovered for an additional 25-30 minutes, or until the cheese is golden and bubbly. This final step creates a beautiful crust that beckons you to dig in.

Step 11: Rest Before Serving
Once baked to perfection, remove the Zuppa Toscana Casserole from the oven and let it rest for at least 10 minutes. This resting period allows the sauce to set, making serving a breeze. The warm, inviting aroma will surely draw your family to the table, ready for a delicious meal.

Make Ahead Options

These Zuppa Toscana Casserole layers make for an excellent meal prep solution! You can chop the potatoes, cook the sausage, and sauté the onions and kale up to 24 hours in advance, storing them separately in airtight containers in the refrigerator. To maintain the quality, keep the cream sauce mix refrigerated, but wait to combine it all until just before baking to ensure freshness. When ready to serve, simply layer the prepped ingredients in the baking dish, pour the cream sauce on top, and bake as directed. This way, you’ll enjoy a cozy, hearty meal without spending too much time in the kitchen on busy weeknights!
