Ingredients
To make this delicious casserole, gather the following:
- 8 oz bacon, cooked crisp and crumbled (reserve ¼ cup bacon grease)
- 1 lb ground Italian sausage, cooked, crumbled, and drained
- 7 cups thinly sliced russet potatoes
- 1 small white onion, peeled and diced
- 2 tablespoons garlic paste
- 6 packed cups washed and chopped kale leaves, stems removed
- ½ cup flour
- 4 cups chicken broth
- 1 – 1 ½ cups heavy whipping cream
- 1 large egg, beaten and tempered
- Salt and pepper to taste
- 1 ½ cups shredded Parmesan cheese, divided
These ingredients create a comforting and indulgent casserole. The bacon and sausage provide rich, savory flavors, while potatoes and kale add heartiness and nutrition. Flour and heavy cream form a thick, creamy base, and Parmesan cheese adds a golden, cheesy finish.
Preparation Method
1. Preheat and Prepare
Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter or cooking spray to prevent sticking. Preheating ensures even cooking and helps the casserole bake uniformly.
2. Cook Meats and Aromatics
Cook the bacon until crisp, reserving ¼ cup of the bacon grease. Crumble the bacon and set aside. In the same skillet, cook the ground Italian sausage until browned and fully cooked, then drain excess fat. Sauté the diced onion in the reserved bacon grease until translucent, about 3–4 minutes, then stir in the garlic paste and cook for another minute.
3. Prepare the Creamy Base
Sprinkle the flour over the cooked onion and garlic, stirring constantly to form a roux. Slowly whisk in the chicken broth and heavy cream, ensuring no lumps remain. Allow the mixture to simmer gently for 3–5 minutes until thickened. Season with salt and pepper to taste.
4. Add Potatoes, Kale, and Meats
Stir in the sliced potatoes, chopped kale, crumbled bacon, and cooked sausage. Cook for another 5–7 minutes until the kale begins to wilt slightly and the potatoes are coated in the creamy sauce. This step ensures that all ingredients are evenly combined and that the flavors meld beautifully.
5. Temper the Egg
Tempering the egg prevents it from curdling when added to the hot mixture. Slowly whisk a few spoonfuls of the hot casserole mixture into the beaten egg, then gradually whisk the egg mixture back into the casserole base. Stir well to ensure a smooth, creamy texture.
6. Assemble and Top
Pour the mixture into the prepared baking dish. Sprinkle 1 cup of the shredded Parmesan cheese over the top, reserving the remaining ½ cup for serving. Spread evenly to cover the casserole surface.
7. Bake
Bake in the preheated oven for 30–35 minutes or until the top is golden brown and the potatoes are tender. Remove from the oven and let the casserole rest for 5–10 minutes before serving. This resting time allows the casserole to set slightly, making it easier to slice and serve.
8. Serve
Serve your Zuppa Toscana Casserole hot, optionally garnished with the remaining Parmesan cheese or a sprinkle of fresh parsley. Pair it with a crisp salad, garlic bread, or roasted vegetables for a complete Italian-inspired meal.
Tips and Variations
- Potato Options: Yukon Gold or red potatoes can be used instead of russet for a creamier texture.
- Greens: Substitute spinach for kale if preferred, or mix both for added variety.
- Cheese: Add mozzarella for extra melty texture or a Parmesan-Mozzarella blend for richer flavor.
- Make Ahead: Assemble the casserole up to the baking step and refrigerate. Bake when ready to serve, adding 5–10 extra minutes to the cooking time.
- Spice Level: Use spicy Italian sausage or add crushed red pepper flakes for a subtle kick.
Nutritional Benefits
This casserole is hearty and nutritious. Bacon and sausage provide protein, while kale adds fiber, vitamins A, C, and K. Potatoes contribute complex carbohydrates and potassium, while the creamy base adds richness and calcium. Using fresh kale and moderate cream keeps the dish balanced while still indulgent enough for a comfort meal.
