Ingredients Notes
Let’s chat about what goes into this beauty—it’s all stuff you might already have, which I love.
Meat & Fat
- 8 oz bacon, cooked crisp & crumbled (reserve ¼ cup bacon grease): That crispy bacon is key, and oh, saving that grease? It’s what makes the sauce so rich.
- 1 lb ground Italian sausage, cooked, crumbled & drained: I go for mild Italian sausage because it’s got just enough kick without overwhelming the dish.
Vegetables
- 7 cups thinly sliced russet potatoes: These soak up all the goodness—slice them thin so they cook evenly, ok?
- 1 small white onion, peeled & diced: Adds a little sweetness to balance the savory vibes.
- 2 tbsp garlic paste: Because who doesn’t love that garlicky punch, right?
- 6 packed cups chopped kale leaves, stems removed: It’s a healthy twist that wilts into the mix—don’t skip it!
Liquid & Binding
- 4 cups chicken broth: Keeps everything juicy and ties the flavors together.
- 1 ¼ cups heavy whipping cream: Mmm, this makes it creamy and dreamy—don’t skimp here.
- 1 large egg, beaten & tempered: Sounds fancy, but it’s just a little trick for a smooth, thick sauce.
Thickening & Seasoning
- ½ cup flour: Helps thicken that sauce so it’s not runny—very important!
- Salt & pepper, to taste: Add as you go; you can totally tweak it to your liking.
Cheese
- 1 ¾ cups shredded Parmesan cheese, divided: This is the star—melty, nutty, and oh-so-good.
Step-by-Step Instructions for Zuppa Toscana Casserole
Now, let’s get cooking! These steps are super easy, and I’ll walk you through it like we’re in the kitchen together.
Step 1: Prep the Base
Start by layering those 7 cups thinly sliced russet potatoes in an even spread across a 9×13 baking dish—you want every bite to have that starchy goodness. Next, sprinkle the cooked 1 lb ground Italian sausage and crumbled 8 oz bacon over the top. It’s like building a flavor foundation, and trust me, it’s already smelling amazing. Keep that ¼ cup bacon grease handy—we’re using it soon!
Pro Tip: Slice the potatoes super thin (about ⅛ inch) so they cook through perfectly—nobody likes a crunchy surprise here.
Step 2: Sauté the Good Stuff
Grab that skillet you cooked the meat in and pour back the ¼ cup bacon grease—set it over medium heat. Toss in the 1 small diced white onion and 2 tbsp garlic paste, stirring for about 2-3 minutes until they soften up and smell incredible. Now, add the 6 packed cups chopped kale and stir just until it wilts—it’s quick, like 30 seconds. This step is where the magic starts, for real.
Pro Tip: Don’t overcook the kale here—it’ll keep cooking in the oven, so just a little wilt is all you need.
Step 3: Build the Sauce
Sprinkle ½ cup flour over the skillet goodies and stir it in—let it cook for about a minute to get rid of that raw flour taste. Slowly whisk in the 4 cups chicken broth, watching it thicken slightly as it simmers—mmm, so satisfying. Pour in the 1 ¼ cups heavy whipping cream and stir until it’s all smooth and creamy. You’re basically making a Parmesan cheese sauce base here.
Pro Tip: Whisk constantly when adding the broth to avoid lumps—smooth sauce is the goal!
Step 4: Temper the Egg
This part’s easy, I promise. Scoop out a tablespoon of that hot skillet liquid into a small bowl, add the 1 large beaten egg, and stir. Add another tablespoon, stir again, then one more—just a little at a time. Pour this back into the skillet, whisking fast so it blends in silky smooth. It’s a bit of a trick to keep things rich without scrambling the egg.
Pro Tip: Go slow with the hot liquid—too fast, and you’ll end up with egg bits instead of a creamy boost.
Step 5: Add the Cheese & Combine
Stir in ¾ cup shredded Parmesan cheese (half of your total) into the skillet until it melts—oh, you’ll love this part. Once it’s smooth, pour this dreamy sauce evenly over the potatoes and meat in the baking dish. It’s like a cozy blanket for your casserole, honestly. Make sure it seeps into every corner.
Pro Tip: Spread the sauce with a spatula if needed—every potato deserves some love.
Step 6: Bake It Up
Cover the dish tight with foil and pop it into a 400°F oven for 50-60 minutes—the potatoes need this time to get tender. Pull off the foil, sprinkle the remaining 1 cup Parmesan cheese on top, and bake uncovered for another 25-30 minutes until it’s golden and bubbly. When it’s done, let it sit for 10 minutes—trust me, it’s worth it for that sauce to set.
Pro Tip: Check the potatoes with a fork before adding the final cheese—they should be soft but not mushy.
Storage and Serving
Leftovers? No problem—this Zuppa Toscana Casserole stores like a dream. Pop it into an airtight container and keep it in the fridge for up to four days—easy peasy. When you’re ready to reheat, warm it in a skillet over medium heat for that crispy edge, or zap it in the microwave if you’re in a rush. It’s still so tasty the next day, you’ll almost look forward to leftovers.
Tips for Success
Want to nail this every time? Here’s what I’ve learned works best. First, cook the bacon extra crispy—it adds such a nice crunch. Don’t skip tempering the egg—it’s a little step that makes the sauce velvety. And for extra flavor, let the Italian sausage brown well before crumbling—it’s a game-changer. Oh, and if your kale looks wilty, rinse it first—it perks right up.
Variations
Love tweaking recipes? Try these fun twists. For a healthier vibe, swap the heavy cream for half-and-half—still creamy, just a bit lighter. Want a spicy kick? Add some red pepper flakes with the sausage—it’s seriously good. Or, for a low-carb option, ditch the potatoes and use cauliflower instead—it’s a macro meal prep win.
