Cook the lasagna noodles in salted water for about 5-7 minutes, cover them with aluminum foil so they don't dry out, and let them cool. Heat some olive oil in a pan over medium heat and brown the Italian sausage. Add the onion, garlic, thyme and let everything cook a bit. Stir in the tomatoes and pasta sauce, season with salt and pepper, and let the sauce boil down.
Preheat the oven to 350°F and cut ⅔ of the cooked lasagna noodles in half diagonally to create triangles. Line a greased 9-inch pie dish with the triangle noodles, as shown in the video.
Spread half of the meat sauce over the lasagna noodles in the pie dish and sprinkle half of the mozzarella and parmesan cheese on top. Fold the chopped basil leaves into the ricotta cheese, spread it over the shredded cheese, and sprinkle pepper on top. Top with the rest of the mozzarella and parmesan cheese, followed by the rest of the meat sauce.
Take the remaining cooked lasagna noodles, stick 2 together side by side, and cut them lengthwise into about ¾-inch thick strips. Weave the cooked lasagna noodle strips together, place the lattice on top of the lasagna pie, and cut off any excess noodles. Brush melted butter over the pie lattice, transfer the pie dish to the oven, and cook for 45 minutes.
