How to Make Zuppa Toscana Casserole

Creating this delightful Zuppa Toscana Casserole is simpler than you think. Follow these clear steps for a perfect meal.
- Preheat your oven to 400°F (200°C). Lightly grease a 9×13-inch baking dish.
- Spread the thinly sliced russet potatoes in an even layer across the bottom of the prepared baking dish.
- Next, evenly spread the cooked, crumbled Italian sausage and crispy bacon over the potato layer.
- Return the reserved 1/4 cup of bacon grease to the same large skillet you used for the sausage and bacon. Place the skillet over medium heat.
- Add the diced white onion and garlic paste to the skillet. Stir these ingredients to combine, then sauté for 2-3 minutes until the onions begin to soften.
- Add the washed and chopped kale leaves to the skillet. Stir the kale just until it wilts down, about 1-2 minutes.
- Sprinkle the all-purpose flour evenly over the vegetables in the skillet. Stir well to coat everything, and cook for 60 seconds, letting the flour cook out slightly.
- Gradually pour the chicken broth into the skillet, whisking constantly to prevent lumps. Continue to whisk and simmer the mixture until it slightly thickens.
- Stir in the heavy whipping cream until it is thoroughly and smoothly incorporated into the creamy sauce.
- In a small mixing bowl, add the beaten large egg. Carefully transfer a tablespoon of the hot sauce from the skillet into the bowl with the egg, stirring quickly to temper the egg. Add another tablespoon of hot liquid, then one more, continuing to stir.
- Pour the tempered egg mixture back into the skillet with the sauce, whisking vigorously to ensure it combines smoothly without scrambling.
- Stir in half of the shredded Parmesan cheese into the skillet sauce. Continue stirring until the cheese is completely melted and the sauce is smooth.
- Carefully pour the creamy sauce mixture evenly out over the layered potatoes, sausage, and bacon in the baking dish.
- Cover the baking dish tightly with aluminum foil. Bake the Zuppa Toscana Casserole in the preheated oven for 50-60 minutes, allowing the potatoes to become tender.
- Remove the foil from the dish. Evenly sprinkle the remaining shredded Parmesan cheese over the top of the casserole.
- Return the uncovered dish to the oven and bake for another 25-30 minutes, or until the cheese is golden brown and bubbly, and the casserole is heated through.
- Carefully remove the hot Zuppa Toscana Casserole from the oven. Let it rest for at least 10 minutes before serving. This resting period helps the sauce set beautifully. Serve warm and enjoy!
Pro Tips for the Best Zuppa Toscana Casserole

Elevate your homemade Zuppa Toscana Casserole with these helpful tips:
- Slice potatoes thinly and uniformly. This ensures even cooking and tender results throughout the dish.
- Temper eggs slowly for smooth sauce. Gradually introducing hot liquid prevents the egg from scrambling.
- Don’t skip resting time for set sauce. Allowing the casserole to rest lets the creamy sauce thicken and prevents it from being too runny.
- Adjust Italian sausage spice level to preference. Choose mild, medium, or hot sausage to match your taste.
- Thoroughly drain cooked sausage/bacon. This step prevents the casserole from becoming greasy.
Kale is a nutritional powerhouse, as highlighted by Healthline, being rich in antioxidants, vitamins C and K, and beta-carotene. Explore the full benefits of incorporating kale into your diet.
- Ensure kale is stemmed and washed well. Remove tough stems for better texture and clean the leaves properly.
- Taste and adjust seasonings before baking. Add extra salt and pepper to the sauce to perfect its flavor.
