Zuppa Toscana Casserole Ingredients
For the Casserole
• Bacon – Adds a smoky flavor and crispy texture; reserve 1/4 cup of grease for cooking.
• Ground Italian Sausage – Provides hearty protein and flavor; make sure it is fully cooked and crumbled.
• Russet Potatoes – Contributes moisture and bulk; thinly slice for even cooking.
• White Onion – Adds sweetness and aroma; any variety can be substituted.
• Garlic Paste – Enhances flavor; can use minced garlic as an alternative.
• Kale – Provides nutrition and texture; ensure stems are removed and chop the leaves.
• Flour – Thickens the cream sauce; can be replaced with gluten-free flour if needed.
• Chicken Broth – Acts as the liquid base for the sauce; use low-sodium broth to manage salt levels.
• Heavy Whipping Cream – Adds richness; substitute half-and-half or whole milk for a lighter option.
• Large Egg – Helps bind the sauce; temper it to avoid curdling.
• Parmesan Cheese – Gives a cheesy flavor and helps in browning; add mozzarella for extra cheesiness.
Step‑by‑Step Instructions for Zuppa Toscana Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (204°C). This crucial first step ensures that the Zuppa Toscana Casserole will bake evenly and develop a wonderful golden top. Set your timer for about 10–15 minutes to allow your oven to reach the perfect temperature while you prepare your ingredients.
Step 2: Prepare the Potatoes
Grease a 9×13-inch baking dish with a little oil or butter to prevent sticking. Next, arrange the thinly sliced Russet potatoes in an even layer across the bottom of the dish. Spread them out so each potato slice lies flat, creating a hearty base for your comforting casserole.
Step 3: Layer the Sausage and Bacon
Once the potatoes are in place, evenly distribute the cooked and crumbled ground Italian sausage over the potato layer. Follow this with the crispy bacon pieces, ensuring that every portion gets a hint of that smoky flavor. This combination brings a delightful heartiness that’s at the core of the Zuppa Toscana Casserole.
Step 4: Sauté the Aromatics
Using the reserved bacon grease in a skillet, heat it over medium-high heat. Add the diced white onion and garlic paste, sautéing for about 2-3 minutes until the onions are soft and translucent. This step releases a delightful aroma, enhancing the flavor profile of your casserole as it builds.
Step 5: Cook the Kale
Incorporate the chopped kale into the skillet with the softened onions and garlic. Cook for an additional 2-3 minutes, or until the kale wilts down and brightens in color. This not only adds nutrition but also vibrant green hues to your Zuppa Toscana Casserole, making it visually appealing.
Step 6: Create the Sauce
Sprinkle ¼ cup of flour into the skillet with the sautéed kale and stir continuously for about 1 minute to cook out the raw flour taste. Gradually whisk in the chicken broth, allowing it to simmer until it slightly thickens. This should take about 3-4 minutes, creating a creamy base for your casserole.
Step 7: Add the Cream
Stir in the heavy whipping cream until fully combined with the thickened broth mixture. This step gives your Zuppa Toscana Casserole its rich and luscious texture. Continue to cook for another minute, just until everything is warmed through and the mixture is silky smooth.
Step 8: Temper the Egg
In a separate bowl, beat a large egg and gradually mix in a scoop of the hot sauce from the skillet to temper it. This helps prevent curdling. Once combined, pour this mixture back into the skillet along with half of the Parmesan cheese, stirring well to integrate the flavors.
Step 9: Assemble the Casserole
Pour the creamy sauce evenly over the layered potatoes, sausage, and bacon in the baking dish. Ensure the sauce coats everything, settling into the layers to imbue them with flavor. This will create a deliciously cohesive dish that embodies the essence of Zuppa Toscana.
Step 10: Bake Covered
Cover the baking dish tightly with foil and place it in your preheated oven. Bake for 50-60 minutes, or until the potatoes are fork-tender. This slow cooking allows the flavors to meld beautifully and the casserole to set without drying out.
Step 11: Add Cheese and Bake Uncovered
After the initial baking time, carefully remove the foil and sprinkle the remaining Parmesan cheese on top of the casserole. Return it to the oven to bake uncovered for an additional 25-30 minutes, allowing the cheese to melt and create a golden, bubbly crust on your Zuppa Toscana Casserole.
Step 12: Rest and Serve
Once baked to perfection, remove the casserole from the oven and let it rest for 10 minutes before serving. This resting time helps the layers settle, making it easier to serve. Dive into this comforting dish while it’s warm, and enjoy the creamy goodness of your Zuppa Toscana Casserole!

Make Ahead Options
These Zuppa Toscana Casserole preparations are perfect for busy weeknights and make meal planning a breeze! You can cook the sausage, bacon, and sauté the onions and kale up to 3 days in advance; simply refrigerate them in airtight containers. Additionally, the sliced potatoes can be prepared and stored overnight in water to prevent browning. When you’re ready to serve, layer the prepped ingredients and pour the sauce over them, then bake directly from the fridge (adding a few extra minutes to the baking time if needed). This way, you’ll enjoy a fresh, hearty casserole that’s just as delicious as if it were made from scratch that day!

Zuppa Toscana Casserole Recipe FAQs
What type of potatoes work best for this casserole?
Absolutely! I recommend using Russet potatoes for their creaminess and ability to hold up during baking. Thin slices ensure they cook evenly; so, take your time when slicing them!

For best results, store your leftovers tightly wrapped or in an airtight container in the fridge for up to 4 days. This keeps them fresh and tasty, ready for a quick meal anytime!

How can I prevent the egg from curdling in the sauce?
Great question! To avoid curdling, you’ll want to temper the egg by gradually mixing a small amount of the hot sauce from the skillet into the beaten egg. Stir continuously until it’s warmed up, then mix it back into the sauce. This keeps everything creamy and delightful!
Are there dietary adjustments I can make for allergies or specific diets?
Definitely! You can replace the heavy cream with coconut milk for a dairy-free version or use gluten-free flour instead of regular flour for those avoiding gluten.
