Ingredients
-
12 lasagna noodles
-
2 cups cooked prime rib, thinly sliced or shredded
-
4 cups Alfredo sauce (store-bought or homemade)
-
2 cups shredded mozzarella cheese
-
1 ½ cups ricotta cheese
-
1 cup grated Parmesan cheese
-
1 teaspoon garlic powder
-
1 teaspoon onion powder
-
1 teaspoon dried Italian herbs (basil, oregano, thyme)
-
2 tablespoons olive oil
-
Salt and pepper, to taste
-
Fresh parsley, chopped (for garnish)
Directions
-
Preheat the oven: Set your oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish with olive oil or cooking spray.
-
Cook the lasagna noodles: Bring a large pot of salted water to a boil. Cook the noodles according to package instructions until al dente. Drain and lay them flat on a clean kitchen towel to prevent sticking.
-
Prepare the cheese mixture: In a medium bowl, combine ricotta cheese, half of the Parmesan cheese, garlic powder, onion powder, Italian herbs, salt, and pepper. Mix until smooth and well incorporated.
-
Layer the lasagna: 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 cheese mixture over the noodles, then 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.
-
Bake the lasagna: 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 and the edges are slightly golden.
-
Rest before serving: Let the lasagna sit for 10-15 minutes before slicing. This allows the layers to set and makes serving easier.
-
Garnish and serve: Sprinkle with freshly chopped parsley for a pop of color and added freshness. Serve warm with a side salad or garlic bread for a complete meal.
Tips for the Perfect Prime Rib Alfredo Lasagna
-
Use quality prime rib: Leftover prime rib works beautifully, but fresh roasted prime rib can take this lasagna to the next level. Slice it thinly for even layering.
-
Homemade Alfredo sauce: While store-bought Alfredo sauce is convenient, making it from scratch with butter, cream, and Parmesan cheese adds a luxurious richness.
-
Cheese variations: Don’t be afraid to experiment. Adding provolone or fontina can enhance the creaminess and depth of flavor.
-
Avoid soggy noodles: Ensure your noodles are drained well and laid flat after boiling. Slightly undercooking them is okay because they will finish cooking in the oven.
-
Make ahead: Assemble the lasagna a day ahead, cover tightly, and refrigerate. Bake it the next day, adding an extra 10-15 minutes to the baking time.
Frequently Asked Questions
-
Can I use frozen lasagna noodles?
Yes, frozen lasagna noodles can be used. Follow the package instructions for cooking, and be sure they are fully thawed before layering to ensure even cooking. No pre-boiling is necessary for no-boil noodles, but make sure your Alfredo sauce is slightly thinner to allow proper cooking. -
What can I use instead of prime rib?
While prime rib gives this dish its rich flavor, other cuts of beef like ribeye, sirloin, or even leftover roast beef can work. For a lighter version, shredded rotisserie chicken can also be used, keeping the creamy texture but reducing the overall heaviness. -
How long can I store leftovers?
Store leftover lasagna in an airtight container in the refrigerator for up to 4 days. To reheat, cover with foil and bake at 350°F (175°C) for 20-25 minutes, or until warmed through. Individual portions can also be reheated in the microwave for convenience. -
Can I freeze this lasagna?
Absolutely! Assemble the lasagna in a freezer-safe dish, cover tightly with foil, and freeze for up to 3 months. Bake from frozen at 375°F (190°C) for 60-70 minutes, or until heated through and bubbly. This makes it a great make-ahead option for busy nights or special occasions.

Health & Nutrition Notes
