Recipe Origin or Trivia

Though not traditionally Tuscan, the soup’s key ingredients—potatoes, kale, sausage, and cream—take cues from rustic Italian cooking. This baked version is an American twist on a beloved classic, turning the comforting soup into a one-dish meal that’s equal parts nostalgic and satisfying.

Instructions for Making Zuppa Toscana Casserole

Now for the good part—let’s layer up this comfort food masterpiece.

1. Preheat Your Equipment: Preheat your oven to 375°F and lightly grease a 9×13 baking dish.
2. Combine Ingredients: In a skillet, cook the bacon until crisp. Remove and reserve ¼ cup of the grease. In the same skillet, cook and crumble the Italian sausage until browned. Set both aside.
3. Prepare Your Cooking Vessel: In a saucepan, heat the reserved bacon grease over medium heat. Whisk in the flour to make a roux and cook for 1 minute. Gradually whisk in the chicken broth and bring to a simmer. Stir in heavy cream. In a small bowl, temper the beaten egg with a spoonful of hot liquid, then stir it into the sauce. Season with salt and pepper to taste. Add half of the Parmesan cheese and stir until melted.
4. Assemble the Dish: Layer half the sliced potatoes in the baking dish. Top with cooked sausage, sautéed onion, garlic paste, chopped kale, and half the bacon. Pour half the cream sauce over the layer. Repeat with remaining potatoes, sauce, and top with remaining bacon and Parmesan cheese.
5. Cook to Perfection: Cover with foil and bake for 40 minutes. Remove foil and bake an additional 15–20 minutes until golden and bubbly.
6. Finishing Touches: Let the casserole rest for at least 10 minutes before slicing to help everything set.
7. Serve and Enjoy: Cut into hearty squares and serve warm with crusty bread or a green salad.

Texture & Flavor Secrets

This casserole is the perfect blend of soft and crispy. The potatoes become fork-tender, the kale adds bite, and the bacon and sausage give it just the right chew and snap. The sauce is creamy but not heavy, with the nutty Parmesan pulling everything together.

Cooking Tips & Tricks

A few thoughtful tips to elevate your casserole game.

• Use a mandoline for even potato slices and consistent baking.
• Massage the kale with a bit of olive oil to soften it slightly before adding.
• Add a pinch of red pepper flakes to the sauce for a subtle kick.
• Make it the night before, then bake the next day for an easy dinner.

What to Avoid

These common mistakes can make or break your casserole.

• Skipping the roux: The sauce won’t thicken properly without it.
• Overloading the dish: Keep layers even to ensure everything cooks through.
• Under-seasoning: Potatoes soak up flavor, so season each layer lightly.
• Adding raw kale without chopping: Large pieces won’t soften properly.
