Lasagna like Grandma used to make

This definitive lasagna has tomato sauce, chunks of meat and two kinds of cheese and sauce. It's made from scratch, just like Grandma's. Enjoy.

Grandma's Lasagna

Serves 10-12

1Ú4 cup extra-virgin olive oil

1Ú2 pound ground beef chuck

1Ú2 pound ground sirloin

4 teaspoon finely chopped garlic

1Ú2 teaspoon dried oregano, crumbled

1Ú4 teaspoon crushed red pepper

2 tablespoon tomato paste

2 28-ounce cans Italian peeled tomatoes, finely chopped with juiced reserved

28-ounce can tomato purée

2 cups chicken stock or low-sodium chicken broth

2 bay leaves

6 thyme sprigs, tied together with kitchen string

Pinch of sugar

Salt and pepper

11Ú2 pounds sweet italian sausage, casings removed

2 pounds fresh ricotta cheese

1Ú4 cup finely chopped flat leaf parsley

2 tablespoons finely chopped basil

1Ú2 cup freshly grated parmesan cheese

1 pound packaged whole milk mozzarella, shredded

1 egg

12 dried lasagna noodles

In a large enameled cast-iron casserole dish, heat the olive oil over high heat until simmering. Add the chuck and sirloin and cook over moderately high heat, breaking up the meat into large chunks, until no pink remains.

Add the garlic, oregano and crushed red pepper and cook until fragrant. Stir in tomato paste and cook until meat is coated. Add the tomatoes and their juices and the tomato purée along with the chicken stock, bay leaves, thyme and sugar. Season with salt and pepper and bring to a boil.

Simmer over moderate heat, stirring occasionally, until thickened and reduced to 8 cups, about 11Ú2 hours. Remove bay leaves and thyme sprigs.

Meanwhile, heat a large skillet. Add the sausage meat and cook until browned and cooked through, about 10 minutes. Drain sausage and break into 11Ú2-inch pieces.

In a large bowl, combine ricotta, parsley, basil and 1Ú4 cup parmesan cheese. Add two-thirds of the shredded mozzarella and season with the salt and pepper. Beat in the egg.

In the large pot of boiling water, cook the lasagna noodles, stirring occasionally, until al dente. Drain and rinse under cold water. Dry the noodles between layers of paper towels.

Preheat the oven to 375 degrees. Spread one cup of sauce in the bottom of the 9-by-13-inch glass baking pan. Line the dish with four overlapping noodles. Spread half of the ricotta mixture over the noodles, then top with half the sausage, 11Ú2 cups of sauce and four more noodles.

Repeat the layering with remaining ricotta mixture, sausage and another 11Ú2 cups of sauce.

Toss the remaining mozzarella and parmesan and sprinkle over lasagna.

Bake for 45 minutes, or until the top is golden and crisp around the edges and the filling is bubbling. Let the lasagna rest for 20 minutes before serving.
