Step‑by‑Step Instructions for Zuppa Toscana Casserole

Step 1: Preheat and Prepare
Start by preheating your oven to 400°F (200°C). While it warms up, generously grease a 9×13-inch baking dish to prevent sticking and ensure a golden finish. This dish will hold all the delicious layers of the Zuppa Toscana Casserole, making it ready for mouthwatering goodness.

Step 2: Layer the Potatoes
Thinly slice the russet potatoes and layer them evenly across the bottom of the prepared baking dish. This creates a solid base for your casserole, allowing the potatoes to absorb all the flavorful juices released during baking. Ensure the potato slices are overlapping slightly for even cooking.

Step 3: Add the Meats
Next, spread the crumbled Italian sausage and crispy bacon over the potato layer. Make sure the sausage is fully cooked and well-distributed to deliver rich flavor throughout the casserole. The savory combination of sausage and bacon will enhance the comforting essence of the Zuppa Toscana.

Step 4: Sauté the Aromatics
In a skillet, heat the reserved bacon grease over medium heat. Add the diced onion and garlic paste, sautéing for 2-3 minutes until the onion is softened and fragrant. This step builds an aromatic foundation for your sauce, adding depth to the Zuppa Toscana Casserole’s flavor profile.

Step 5: Incorporate the Kale
Stir in the chopped kale, cooking for an additional 2-3 minutes until wilted. The vibrant green color will enhance the dish, and the kale’s nutrients add an extra healthful component to your casserole. This step is not just about flavor; it also introduces beautiful color.

Step 6: Create the Sauce
Sprinkle flour over the kale mixture, stirring for about 1 minute to eliminate the raw flour taste. Gradually whisk in chicken broth and let it simmer until the sauce thickens, about 3-5 minutes. This creamy mixture will bind all elements together, enriching the overall character of the Zuppa Toscana Casserole.

Step 7: Add Cream for Richness
Pour the heavy whipping cream into the skillet, stirring until smooth and well combined. Allow the mixture to heat through without boiling, which will create a luscious creamy sauce that envelops the casserole, enhancing the richness and flavor.

Step 8: Temper the Egg
To incorporate the beaten egg smoothly, temper it by adding a few tablespoons of the hot sauce from the skillet. Whisk this mixture back into the sauce, ensuring it thickens beautifully without curdling. This technique helps create that velvety texture that defines the Zuppa Toscana Casserole.

Step 9: Mix in Parmesan Cheese
Stir in half of the grated Parmesan cheese until melted and fully integrated, adding a savory depth to the sauce. The cheese will enhance the umami flavor of your casserole while contributing to its creamy consistency, making every bite indulgent.

Step 10: Assemble and Cover
Pour the rich sauce evenly over the layered potatoes, sausage, and bacon in the baking dish. Tightly cover the dish with aluminum foil to trap steam, allowing the potatoes to cook through and soften beautifully as the casserole bakes.

Step 11: Bake Covered
Place the covered casserole in the preheated oven and bake for 50-60 minutes. The steam will help cook the potatoes until tender, so check for doneness with a fork. The potatoes should be soft enough to pierce easily when it’s time to uncover.

Step 12: Final Bake and Serve
Remove the foil and sprinkle the remaining Parmesan cheese over the top. Return it to the oven and bake uncovered for an additional 25-30 minutes, until the cheese is golden and bubbly. Let the Zuppa Toscana Casserole rest for 10 minutes before digging in, allowing the flavors to settle.

How to Store and Freeze Zuppa Toscana Casserole

Fridge: Store leftovers in an airtight container for up to 4 days. Allow the casserole to cool completely before sealing to maintain freshness.

Freezer: For longer storage, freeze the casserole tightly wrapped in aluminum foil or a freezer-safe container for up to 3 months. Thaw overnight before reheating.

Reheating: To enjoy your Zuppa Toscana Casserole again, reheat in the oven at 350°F (175°C) for 20-25 minutes, or until heated throughout. You can also use a microwave for quicker options—heat in short intervals, stirring between.

Serving Reminder: Let it rest for 5-10 minutes after reheating to enable the flavors to meld beautifully before serving.
