Instructions

Preheat the oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish with olive oil or cooking spray.
Bring a large pot of salted water to a boil and cook the lasagna noodles according to package instructions until al dente. Drain and lay them flat on a clean kitchen towel to prevent sticking.
In a medium bowl, combine ricotta cheese, half of the Parmesan cheese, garlic powder, onion powder, Italian herbs, salt, and pepper. Mix until smooth.
Spread ½ cup of Alfredo sauce on the bottom of the prepared baking dish. Lay three lasagna noodles over the sauce. Spread a layer of the ricotta mixture over the noodles, top with ⅓ of the prime rib slices, and ⅓ of the shredded mozzarella. Drizzle with ½ cup of Alfredo sauce.
Repeat the layering process twice more, finishing with a layer of noodles topped with remaining Alfredo sauce, mozzarella, and Parmesan cheese.
Cover the dish with aluminum foil and bake for 25 minutes. Remove the foil and bake for an additional 15-20 minutes, or until the cheese is melted and bubbly.
Let the lasagna rest for 10-15 minutes before slicing to allow the layers to set.
Garnish with freshly chopped parsley and serve warm.

Notes

Leftover prime rib works best, but fresh roasted prime rib or other beef cuts can be used.
For extra richness, make Alfredo sauce from scratch with butter, cream, and Parmesan cheese.
Slightly undercook noodles to prevent sogginess; they will finish cooking in the oven.
This lasagna can be assembled a day ahead and baked later, adding 10-15 minutes to the bake time.
Leftovers can be stored in the refrigerator for up to 4 days or frozen for up to 3 months.
