INGREDIENTS
For bolognese sauce:
1/4 cup olive oil
3 ounces sliced pancetta, finely chopped
1 medium onion, finely chopped
1 large carrot, finely chopped
1 celery rib, finely chopped
2 garlic cloves, chopped
2 pounds ground beef chuck (not lean)
1 1/2 cups dry white wine
1 1/2 cups whole milk
1/4 cup tomato paste
1 1/2 teaspoon thyme leaves
For Ricotta filling:
2 (10-ounce) packages frozen chopped spinach,thawed
2 (15-ounce) containers whole-milk ricotta
4 large eggs, lightly beaten
1/2 cup grated Parmigiano-Reggiano
1/2 teaspoon grated nutmeg
3/4 cup whole milk, divided
For assembling lasagne:
12 Barilla no-boil dried lasagne noodles (from 1 box)
1/2 cup grated Parmigiano-ReggianoDIRECTIONS
- Make Sauce: heat oil in a 12-to 14-inch heavy skillet over medium heat until it shimmers. Cook pancetta, onion, carrot, celery, and garlic, stirring occasionally, until vegetables are golden and softened, 12 to 15 minutes.
- Add beef and cook, stirring occasionally and breaking up any lumps, until meat is no longer pink, 6 to 10 minutes.
- Stir in wine, milk, tomato paste, thyme, 1/4 teaspoon salt, and 3/4 teaspoon pepper. Simmer, uncovered, stirring occasionally, until most of liquid has evaporated but sauce is still moist, about 1 hour.
- Make ricotta filling: put spinach in a kitchen towel (not terry cloth) and twist to squeeze out as much moisture as possible.
- Whisk together ricotta, eggs, parmesan, nutmeg, 1 1/4 teaspoons salt, and 1 teaspoon pepper.
- Transfer 1 1/2 cups ricotta mixture to another bowl and whisk in 1/4 cup milk; set aside.
- Whisk spinach into remaining filling with remaining 1/2 cup milk.
- Assemble and bake lasagne: preheat oven to 375°F with rack in middle.
- Soak noodles in a bowl of very warm water until pliable but not softened, 3 to 5 minutes. Place on a kitchen towel (it's not necessary to pat noodles dry).
- Spread 1 1/2 cups bolognese sauce in baking pan and sprinkle with 1 tablespoon parmesan. Cover with 3 noodles, leaving space in between.
- Spread half of spinach filling on top, then 1 cup bolognese sauce, and top with 1 tablespoon parmesan and 3 noodles; repeat.
- Top with remaining bolognese sauce, 1 tablespoon parmesan, and remaining 3 noodles. Pour reserved ricotta mixture over top and sprinkle with remaining 1/4 cup parmesan.
- Cover pan tightly with parchment paper and foil (or just buttered foil) and bake 50 minutes.
- Remove foil and bake until top is browned in spots, about 15 minutes more. Let stand 15 to 30 minutes before cutting.
Serves 8-10.
Make ahead: Bolognese sauce can be made 2 days ahead and chilled (covered once cool). Lasagne can be made 1 day ahead and chilled. Reheat in a 350°F oven, loosely covered with foil.
