Zuppa Toscana Casserole Ingredients
For the Base
• Bacon (8 oz) – Adds savory flavor and crispy texture. Substitute turkey bacon for a lighter option.
• Ground Italian Sausage (1 lb) – Provides a rich, seasoned protein base. Choose mild or spicy based on preference.
• Russet Potatoes (7 cups, sliced thin) – Offers bulk and creamy texture when baked. Yukon gold potatoes are a good alternative.
• White Onion (1 small) – Adds sweetness and depth of flavor. Any onion variety can be used if white is unavailable.
• Garlic Paste (2 tbsp) – Enhances the overall flavor profile. Fresh minced garlic is a suitable substitute.
For the Green Touch
• Kale Leaves (6 cups, washed and chopped) – Provides color, nutrients, and a mild bitterness that balances the richness. Spinach can be used in place of kale.
For the Creamy Sauce
• Flour (1/2 cup) – Acts as a thickening agent for the cream sauce. Cornstarch can be used as a gluten-free alternative.
• Chicken Broth (4 cups) – Adds liquid and depth to the casserole. Vegetable broth can be used for a vegetarian option.
• Heavy Whipping Cream (1-1.5 cups) – Contributes creaminess and richness. Half-and-half can reduce the fat content.
• Large Egg (1) – Binds the sauce and helps set the casserole. For egg-free, use a flaxseed meal/water mixture as a substitute.
Finishing Touches
• Salt and Pepper – Seasons the dish to taste.
• Shredded Parmesan Cheese (1.5 cups) – Offers a salty, cheesy finish. Mix in mozzarella for added flavor and gooeyness.
With these ingredients, you’ll be well on your way to mastering a comforting Zuppa Toscana Casserole that will certainly capture hearts and appetites alike!
Step‑by‑Step Instructions for Zuppa Toscana Casserole
Step 1: Preheat the Oven
Start by preheating your oven to 400°F (200°C). This is essential for creating that golden, bubbly top once your Zuppa Toscana Casserole is ready to bake. While the oven heats, gather your ingredients to ensure a smooth cooking experience, setting the stage for a delightful culinary adventure.
Step 2: Layer the Potatoes
In a 9×13-inch baking dish, layer the thinly sliced russet potatoes evenly across the bottom. These layers will form the hearty base of your casserole. As you arrange them, make sure they overlap slightly so that every bite can enjoy the creamy texture that will develop during baking.
Step 3: Add the Meat
Next, spread the cooked and crumbled ground Italian sausage and crispy bacon over the potato layer. This savory blend will infuse the Zuppa Toscana Casserole with rich flavors, ensuring every bite delights your taste buds. Use the back of a spoon to gently press the meat down for even cooking.
Step 4: Sauté Onions and Garlic
In a skillet over medium heat, add the reserved bacon grease and onion. Sauté until the onion is soft and translucent, around 2-3 minutes. Then, stir in the garlic paste, allowing that warm aroma to fill your kitchen. This fragrant mix will elevate the taste of your casserole wonderfully.
Step 5: Incorporate the Kale
Add the chopped kale to the skillet, stirring until wilted, which should take about 2-3 minutes. The addition of kale not only boosts the nutritional value but also adds a beautiful green color to your Zuppa Toscana Casserole. Once wilted, sprinkle in the flour and cook the mixture for another minute.
Step 6: Create the Creamy Sauce
Slowly whisk in the chicken broth, bringing the mixture to a gentle simmer. Allow it to thicken for about 3-4 minutes, watching closely for a creamy consistency. Afterward, stir in the heavy whipping cream, blending until smooth. This rich sauce will envelop the casserole, creating a luscious texture.
Step 7: Temper the Egg
To bind your sauce, temper the beaten egg by gradually adding a spoonful of the hot sauce to it, preventing the egg from scrambling. Once combined, pour this egg mixture back into the skillet. Stir until fully integrated, ensuring your Zuppa Toscana Casserole has an even, creamy layer throughout.
Step 8: Mix in the Cheese
Sprinkle half of the shredded Parmesan cheese into the sauce, stirring well to mix it in. This will add a rich, salty flavor that perfectly complements the hearty ingredients. Once combined, pour this creamy sauce over the layered potatoes and meat in your baking dish, spreading it evenly for even cooking.
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 become tender. After this time, carefully remove the foil, sprinkle the remaining cheese on top, and return it to the oven for an additional 25-30 minutes until bubbling and golden.
Step 10: Cool and Serve
Once baked, remove the Zuppa Toscana Casserole from the oven and let it sit for 10 minutes. This timing allows the sauce to set, making serving easier. After a short wait, slice and serve your comforting casserole to friends and family, showcasing the rich flavors and cozy essence of this Italian-inspired meal.
