Servings: 10-12

Start to finish: 2 hours

14 curly-edged lasagna noodles

8 ounces (1 cup) cottage cheese

6 1/2 ounces Pecorino Romano cheese, grated (3¼ cups)

1 cup heavy cream

2 garlic cloves, minced

1 tablespoon cornstarch

1/2 teaspoon pepper

3 cups Ragu alla Bolognese (recipe follows), room temperature

2 tablespoons shredded fresh basil

Lay noodles in 13-by 9-inch baking dish and cover with boiling water. Let noodles soak until pliable, about 15 minutes, separating noodles with tip of paring knife to prevent sticking. Place dish in sink, pour off water, and run cold water over noodles. Pat noodles dry with clean dish towel; dry dish and spray with vegetable oil spray. Cut 2 noodles in half crosswise.

Adjust oven rack to middle position and heat oven to 425 F. Whisk cottage cheese, 3 cups Pecorino, cream, garlic, cornstarch, and pepper in bowl until combined.

Spread 1 cup ragu in bottom of prepared dish. Lay 3 noodles lengthwise in dish with ends touching 1 short side, leaving space on opposite short side. Lay 1 half-noodle crosswise in empty space to create even layer of noodles. Spread half of cheese mixture over noodles. Repeat layering of noodles, reversing arrangement of half-noodle, then spread 1 cup ragu over top. Create third layer using 3 1/2 noodles (reversing arrangement again) and remaining cheese mixture. Lay remaining 3 1/2 noodles over cheese mixture. Spread remaining 1 cup ragu over noodles and sprinkle with remaining 1/4 cup Pecorino.

Spray sheet of aluminum foil with oil spray and cover lasagna. Bake until bubbling around edges, about 30 minutes. Remove foil and continue to bake until top is spotty brown, about 10 minutes. Let lasagna cool for 45 minutes. Sprinkle with basil. Cut into pieces and serve.

Ragu alla Bolognese:

Makes about 6 cups; enough for 2 pounds pasta

Shopping Note: Eight teaspoons of gelatin is equivalent to one (1-ounce) box of gelatin. If you can’t find ground veal, use an additional 12 ounces of ground beef.

1 cup chicken broth

1 cup beef broth

8 teaspoons unflavored gelatin

1 onion, chopped coarse

1 large carrot, peeled and chopped coarse

1 celery rib, chopped coarse

4 ounces pancetta, chopped

4 ounces mortadella, chopped

6 ounces chicken livers, trimmed

3 tablespoons extra-virgin olive oil

12 ounces 85 percent lean ground beef

12 ounces ground veal

12 ounces ground pork

3 tablespoons minced fresh sage

1 (6-ounce) can tomato paste

2 cups dry red wine

Salt and pepper

Combine chicken broth and beef broth in bowl; sprinkle gelatin over top and let sit until softened, about 5 minutes.

Pulse onion, carrot, and celery in food processor until finely chopped, about 10 pulses, scraping down sides of bowl as needed; transfer to separate bowl. Pulse pancetta and mortadella in now-empty processor until finely chopped, about 25 pulses; transfer to third bowl. Process chicken livers in again-empty processor until pureed, about 5 seconds; refrigerate until ready to use.

Heat oil in Dutch oven over medium-high heat until shimmering. Add ground beef, veal, and pork and cook, breaking up meat with wooden spoon, until all liquid has evaporated and meat begins to sizzle, 10 to 15 minutes. Stir in pancetta mixture and sage and cook until pancetta is translucent, 5 to 7 minutes, adjusting heat as needed to keep fond from burning. Stir in chopped vegetables and cook until softened, 5 to 7 minutes. Stir in tomato paste and cook until rust-colored and fragrant, about 3 minutes.

Stir in wine, scraping up any browned bits, and simmer until thickened, about 5 minutes. Stir in broth mixture, return to bare simmer, and cook until sauce has thickened (wooden spoon should leave trail when dragged through sauce), about 1 1/2 hours.

Stir in chicken livers and bring to brief simmer. Season with salt and pepper to taste. (Sauce can be refrigerated for up to 3 days or frozen for up to 1 month.)
