Equipment
Method
Prep and preheat
- Preheat the oven to 375°F and grease a 9x13 dish with a thin, even coating so the casserole releases easily.
Brown sausage
- Brown Italian sausage in a skillet over medium-high heat, breaking apart, until cooked through, then drain excess fat and remove.
Build the cream sauce
- Sauté onion in the same pan for 3 minutes, until softened, then add garlic and cook 1 minute until fragrant.
- Pour in heavy cream, then add chicken broth and red pepper flakes and stir to combine.
Layer the casserole
- Layer half the potato slices in the greased dish and spread into an even layer.
- Scatter half the sausage and half the kale over the potatoes, distributing them in a thin, even layer.
- Repeat the layers with the remaining potato slices, then top with the remaining sausage and kale.
Bake until tender
- Pour the cream mixture evenly over everything, pressing down gently so the potatoes make contact with the liquid.
- Top with parmesan cheese, cover with foil, and bake for 25 minutes at 375°F so the potatoes start to soften.
- Remove the foil and bake for 15 more minutes at 375°F, until potatoes are tender and the top is golden.
Notes
Pro tip: slice the potatoes thin and evenly so they cook through at the same rate and the cream base thickens properly. Refrigerate leftovers in an airtight container up to 3 days; reheat covered at 350°F until hot throughout. Freezing isn’t recommended because the cream base can separate after thawing. For a lighter option, use half-and-half in place of heavy cream (the texture will be slightly less rich).
