(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

Directions

1. I preheat the oven to 375°F (190°C) and lightly grease a baking dish.

2. In a skillet over medium heat, I cook the Italian sausage until browned, breaking it apart as it cooks. If needed, I add olive oil.

3. I stir in the diced onion and cook for 3–4 minutes until softened, then add the garlic and cook for another 30 seconds.

4. I add the sliced potatoes, chicken broth, heavy cream, Italian seasoning, red pepper flakes if I’m using them, salt, and black pepper. I let the mixture simmer for about 8–10 minutes, until the potatoes begin to soften.

5. I stir in the chopped kale and let it wilt slightly.

6. I transfer everything to the prepared baking dish and spread it evenly.

7. I sprinkle mozzarella and Parmesan cheese over the top.

8. I bake uncovered for 20–25 minutes, until the potatoes are tender and the cheese is melted and golden.

9. I let the casserole rest for a few minutes before serving.

Servings and Timing

I find this recipe serves about 4–6 people.

• Prep time: 15–20 minutes

• Cook time: 35–40 minutes

• Total time: About 55–60 minutes

Variations

I sometimes use turkey sausage for a lighter option. When I want extra richness, I add a little cream cheese to the sauce. I also like adding mushrooms for extra depth of flavor. For a lower-carb version, I substitute some of the potatoes with cauliflower slices.

storage/reheating

I store leftovers in an airtight container in the refrigerator for up to 4 days. When reheating, I warm individual portions in the microwave or reheat the entire dish in the oven at 350°F (175°C) until heated through. If it thickens too much, I add a small splash of broth before reheating.

FAQs

Can I prepare this ahead of time?

I assemble the casserole ahead and refrigerate it before baking. I add a few extra minutes to the baking time if it’s cold from the fridge.

What type of potatoes work best?

I prefer Yukon Gold or Russet potatoes because they become tender and creamy when baked.

Can I freeze this casserole?

I can freeze it after baking for up to 2 months. I thaw it overnight in the refrigerator before reheating.

How do I make it spicier?

I use hot Italian sausage or increase the amount of red pepper flakes.

Can I make this dairy-free?

I substitute coconut cream for heavy cream and use dairy-free cheese alternatives to keep it dairy-free.

Conclusion
