Prep. Preheat oven to 350º F. Spray a 9×13 baking dish with nonstick cooking spray and set aside. Cook and drain the lasagna noodles. Set aside.: The kitchen will smell clean and faintly of oil as you preheat the oven to 350º F and spray the baking dish. You may hear a faint hiss from the spray and feel the oven warming as it approaches temperature. Getting the oven fully hot ensures even baking throughout. A common mistake here is starting with a cooler oven, which can lengthen baking time and affect texture, so always confirm the temperature before the lasagna goes in.
Make the Meat Sauce. Cook ground beef and Italian sausage in a large skillet over medium heat. Drain the meat well. Stir in the Stone House Seasoning, basil, oregano, pasta sauce and tomato paste. Simmer until sauce has thickened, about 5 to 10 minutes.: As you boil the water and add the lasagna noodles , you will see the water return to a gentle boil and the pasta begin to soften and loosen. The noodles should be cooked until tender yet slightly firm to the bite. Drain them and lay them flat so they do not stick together. If you overcook the noodles they become fragile and can tear when layering, so watch the pot closely and test a noodle early.
Make the Cheese Mixture. Lightly beat the egg in a large mixing bowl. Add the cream cheese, Greek yogurt, 2 cups Mozzarella cheese, 1/4 cup Parmesan cheese, and parsley (optional). Stir to combine well.: When you brown the ground beef and Italian sausage in a large skillet, listen for a steady sizzle and breathe in an aroma that shifts from raw to richly caramelized as the meat browns. After draining fat, add the Stone House Seasoning , basil , oregano , pasta sauce , and tomato paste , then let the mixture simmer until thickened. Simmering concentrates flavors and melds the herbs, and you want the sauce to cling to a spoon rather than run off it. A frequent slip is boiling too vigorously, which can dry the sauce out, so keep it at a gentle simmer.
Layer the Lasagna. Ladle 1 cup Meat Sauce into the prepared 9×13 baking dish. Top with a layer of the lasagna noodles. Spread 1/3 of the Cheese Mixture over the noodles and top with 1 cup of Meat Sauce. Repeat twice. Top with another layer of lasagna noodles and the remaining Meat Sauce.: In a bowl, beat the large egg lightly, then blend in softened cream cheese , plain Greek yogurt , two cups of mozzarella cheese , a quarter cup of Parmesan cheese , and the chopped parsley if using. You should feel the mixture become smooth and slightly glossy as the cheeses incorporate. The egg helps the mixture set while baking, and the yogurt keeps it tangy and light. If the cream cheese is not soft enough you will encounter lumps, so allow it to reach room temperature first.
Bake the Lasagna. Cover lightly with aluminum foil and bake for 40 minutes.: As you spread the first cup of sauce across the bottom, it should look rich and glossy, creating a protective layer that prevents sticking. This base ensures the first noodle layer does not stick to the pan and contributes moisture to the assembly. Skipping this initial sauce layer can lead to sticking and uneven moisture distribution, so do not omit it.
Top with Cheese and Serve. Remove foil and top with remaining 2 cups Mozzarella cheese, 1/4 cup Parmesan cheese. Bake uncovered until browned, about 15 minutes. Rest for 10 minutes before cutting and serving.: Lay the cooked lasagna noodles across the sauce so they slightly overlap, forming a continuous covering. They should look pale and supple, not cracked or dry. Proper placement prevents gaps that can make the final slices fall apart. If you crowd the noodles too tightly they may clump during baking, so give them a gentle, even spread.
Spread 1/3 of the Cheese Mixture over the noodles: Use a spatula to distribute a third of the creamy filling evenly. The surface should appear smooth and slightly domed, with the filling reaching the edges. Even distribution guarantees every portion gets a balanced cheese layer. Rushing this step can leave uneven pockets and lead to dry areas, so take a moment to smooth it carefully.
Top with 1 cup of Meat Sauce: Spoon one cup of the warmed meat sauce on top of the cheese layer so it forms a glossy red blanket. The sauce provides moisture and savory heft; aim for a thin, even spread so the layers remain distinct. Using too much sauce in one layer can cause the lasagna to become watery while baking, so measure portions as instructed.
Repeat twice: Repeat the noodle, cheese mixture, and sauce layering two more times to build structure and depth. As you stack, you will see the lasagna grow taller and the layers alternate in color and texture. This repeating rhythm creates the classic lasagna cross section you want. Be mindful of even layering, a common misstep is creating lopsided stacks which can lead to uneven baking.
Top with another layer of lasagna noodles and the remaining Meat Sauce: Finish the layering with one more noodle layer and spread the remaining sauce across the top so it appears thick and glossy. This final sauce layer helps insulate the top noodles and adds flavor to the finished surface. Avoid leaving dry noodle sections, which can produce chewy spots.
Bake the Lasagna covered: Cover the dish lightly with aluminum foil and bake at 350º F for about 40 minutes . During this time the kitchen will fill with the aroma of simmered tomatoes and toasted cheeses, and you may notice gentle bubbling along the edges under the foil. Baking covered allows the internal layers to steam and heat through without overbrowning the top. A frequent mistake is removing the foil too early, which can dry out the interior.
Remove foil and top with remaining 2 cups Mozzarella cheese and 1/4 cup Parmesan cheese: After the initial bake, take off the foil and scatter the remaining mozzarella cheese and the last quarter cup of Parmesan cheese across the surface. The cheeses will begin to melt and then brown, creating a bubbly, golden crust. Watch closely as the top can shift from nicely browned to overly dark quickly, so aim for a warm golden finish.
Bake uncovered until browned, about 15 minutes: Return the lasagna to the oven uncovered and let it develop a browned, bubbling top for approximately 15 minutes . You will hear a light bubbling and see the cheese pull into small blisters. This final bake creates texture contrast and a visually appealing finish. Leaving it in too long risks drying the edges, so check at about ten minutes and adjust as needed.
Rest for 10 minutes before cutting and serving: Once out of the oven, allow the lasagna to rest for 10 minutes . During this time the steam settles and the layers firm up, making it easier to slice. The aroma will continue to bloom, and the interior temperature will even out. Cutting immediately can cause the layers to collapse and serve sloppy pieces, so patience here improves presentation and portioning.
