Preheat the oven to 350 degrees F/180 degrees C

Make the cheesy sauce by combining all ingredients and blending into a really smooth paste. Set aside.

Place the diced potatoes in a saucepan, cover with water by an inch, then bring to a boil. Cover, turn heat to a simmer, and cook the potatoes 10 minutes or until very tender. Drain out the water and reserve the potatoes.

In a large skillet, heat the oil. Add the onions, garlic, parsley and rosemary (or sage) to the oil. Season with salt and ground black pepper and saute, stirring, for five minutes over medium heat or until the onions are soft.

Add the sausage, red pepper flakes and potatoes and continue to cook, about five minutes. Check seasoning and add more pepper and salt if needed.

If you are using a cast iron or a stove-to-oven skillet, arrange the potato mixture in an even layer and pour the cheesy sauce over it evenly. If using a baking dish, like I did, transfer the potato sausage mixture to the baking dish and pour the cheesy sauce on top.
Transfer the skillet or baking dish to the preheated oven and bake 30 minutes or until the top starts to lightly brown. Switch to the broil function on your oven and broil for another five minutes on the highest setting, or until gold-brown spots appear on the potatoes and cheesy sauce. Garnish with more parsley if you wish, and serve hot or at room temperature.
Store covered in the refrigerator for up to 4 days. Reheat covered at 325°F for 15–20 minutes or in the microwave until warmed through.
High-powered blender or food processor (for cashew sauce)
Yes. Assemble the casserole up to 24 hours ahead, cover, and refrigerate. Bake from cold, adding 10–15 minutes to cooking time.
Soak raw cashews for at least 30 minutes in hot water, drain well, then blend with liquid until smooth. A standard blender works if you allow extra soaking time.
Italian sausage brands like Field Roast, Beyond Meat, or Yves work well. Choose a firmer variety that holds its shape during cooking.
Red, yellow, and russet potatoes all work. Waxy potatoes like red hold their shape better; starchy russets become fluffier.
Potatoes should be fork-tender and golden brown at the edges, typically 40–50 minutes baked at 375°F.
