Bring a large pot of salted water to a boil. Cook the [San Giorgio lasagna noodles] according to package directions, usually about 8-9 minutes for al dente. Drain and lay the noodles flat on a lightly oiled baking sheet to prevent sticking. Grandma always said, 'Don't overcook the pasta – it'll finish in the oven
In a large skillet or Dutch oven, heat [olive oil] over medium-high heat. Add [ground beef] and [Italian sausage] with casings removed. Break the meat apart with a wooden spoon and cook until browned, about 7-8 minutes. This is where the flavor starts, just like Grandma taught me – take your time with the browning
Add finely diced [onion] and minced [garlic] to the meat. Cook until onions are translucent, about 5 minutes. The kitchen already starts to smell like Sunday dinner at Grandma's house
Stir in [crushed tomatoes], [tomato paste], [tomato sauce], [sugar], [dried basil], [Italian seasoning], [salt], and [black pepper]. Bring to a simmer, then reduce heat to low. Cover and let simmer for at least 30 minutes, stirring occasionally. Grandma would let hers simmer for hours, saying 'Patience makes perfect sauce.
While the sauce simmers, prepare the cheese filling. In a medium bowl, combine [ricotta cheese], beaten [eggs], chopped [fresh parsley], remaining [salt], and 1/4 cup [Parmesan cheese]. Mix well until smooth and creamy. Grandma always said the ricotta mixture was the heart of a good lasagna
Preheat your oven to 375°F (190°C). Get your 9x13-inch baking dish ready – Grandma's recipe card says 'no need to grease it
Spread 1 cup of meat sauce in the bottom of your baking dish. Layer 3-4 [San Giorgio lasagna noodles] over the sauce, slightly overlapping. Spread one-third of the ricotta mixture over the noodles, followed by 1 cup of meat sauce and 1 cup [mozzarella cheese]. I can still see Grandma's hands carefully spreading each layer to the edges.
Repeat the layers twice more, ending with noodles topped with the remaining sauce and [mozzarella cheese]. Sprinkle remaining [Parmesan cheese] on top. Grandma always said, 'Don't skimp on cheese at the top – that golden crust is what makes everyone peek in the oven
Cover the baking dish with aluminum foil, making sure it doesn't touch the cheese. Bake covered for 25 minutes. The foil keeps the moisture in – another trick I learned watching Grandma in her kitchen
Remove the foil and bake for an additional 25 minutes until the top is golden and bubbly. Those last few minutes of watching the cheese brown were always my favorite part of making lasagna with Grandma
Allow the lasagna to rest for 15 minutes before serving. As Grandma's handwritten note says, 'Let it rest before serving, the wait is worth the reward.' This helps the lasagna set so you get perfect slices
