Fix Anthony Bourdain’s lasagne Bolognese recipe for your weekend project

Imagine a heavy baking dish loaded with layer after layer of rich bechamel sauce, grated Parmigiano-Reggiano, noodles, slow-cooked Bolognese sauce, topped with a layer of thinly sliced fresh mozzarella cheese and baked to browned and bubbly perfection. That’s how Anthony Bourdain imagines lasagna, and we were such fans we named the recipe one of our favorite recipes of 2016.

Sure, the dish is time-consuming, clocking in at about 4 hours not including cooling time — good things don’t always come quickly — but it’s a perfect project for a cold and rainy weekend. Best of all? If you happen to have any leftovers, this is one dish that gets only better with time.

LASAGNE BOLOGNESE

Total time: About 4 hours, plus cooling time | Serves 12 to 16

Note: Adapted from a recipe in “Appetites: A Cookbook” by Anthony Bourdain.

BECHAMEL SAUCE

6 tablespoons butter

6 tablespoons flour

1 quart milk

Salt and pepper

Pinch freshly ground nutmeg, optional

1. In a medium, heavy-bottom saucepan, heat the butter over medium heat until it foams and subsides. Whisk in the flour and stir it well using a wooden spoon, incorporating it into the butter until a dry paste forms (a roux). Reduce the heat and continue to cook and stir, taking care not to let the mixture brown.

2. Meanwhile, in a large saucepan, bring the milk to a simmer, then gradually whisk it into the pan with the roux, continuing to whisk until the mixture is smooth. Season with 1/2 teaspoon salt and a pinch of pepper, or to taste, along with the nutmeg, if using. Continue to cook over medium-low heat, stirring regularly, until the sauce is thick enough to coat the back of a wooden spoon, about 10 minutes. This makes about 4 cups bechamel.

LASAGNE BOLOGNESE

3 tablespoons olive oil, divided

1 large white or yellow onion, finely chopped

2 large or 3 medium carrots, finely chopped

3 ribs celery, finely chopped

4 garlic cloves, finely chopped

½ teaspoon fresh thyme leaves

Salt and freshly ground black pepper

½ pound chicken livers, trimmed of connective tissue and fat and finely chopped

¾ pound ground beef chuck

¾ pound ground veal

¾ pound ground pork

¾ cup tomato paste (about 6 ounces)

1 cup Vermentino, Trebbiano or other Tuscan white wine

1 ½ cups milk

2 bay leaves

About 1 pound dry, flat lasagne noodles

4 cups bechamel sauce

¾ cup finely grated Parmigiano-Reggiano cheese

6 ounces fresh mozzarella cheese, thinly sliced

1. To make the Bolognese sauce, in a medium, heavy-bottom pot, heat 2 tablespoons oil over medium-high heat. Add the onion, carrots, celery, garlic and thyme and season with ½ teaspoon salt and several grinds of pepper, or to taste. Cook, stirring regularly using a wooden spoon, until the vegetables are tender and have released their juices, 7 to 9 minutes. Stir in the livers and cook over high heat for 2 minutes, then add the beef, veal and pork, stirring and breaking up over high heat. Season with 1 teaspoon salt and several grinds pepper, or to taste. Continue to cook over high heat until the meat is brown, stirring regularly and scraping the bottom of the pan as necessary to keep the meat and vegetables from scorching.

2. Once the meat is browned, stir in the tomato paste over medium heat. Cook for about 20 minutes, stirring regularly, to marry the flavors. Add the wine, bring to a boil and cook until the wine is reduced by half, then add the milk and bay leaves and bring to a boil. Reduce the heat to a simmer and cook for 1½ to 2 hours, stirring occasionally. You may need to add a bit of water (or chicken or veal stock, if you have it) to thin the sauce if it thickens too much.

3. Taste the sauce and season with 1 teaspoon salt and several grinds of pepper, or as needed. Remove from heat and stir to release the steam and allow it to cool slightly. Skim the fat off the top with a ladle and discard.

4. Heat the oven to 350 degrees.

5. Coat the inside of a 13-inch by 9-inch (or similar size) baking dish with the remaining tablespoon oil. Cover the bottom of the dish with a layer of bechamel. Sprinkle over some grated cheese, then top with a layer of noodles. Top the noodles with a layer of Bolognese sauce, and repeat with the bechamel, grated cheese, noodles, and Bolognese until the pan is filled to the top. The top layer should be Bolognese, dotted with bechamel, with thin slices of mozzarella laid across the top.

6. Place the baking dish on a foil-lined sheet pan and bake in the oven until the lasagna is browned on top and beginning to bubble, about 50 minutes. Remove and set aside to cool. If you must serve it the day you’ve made it, set it aside to rest for 15 minutes before slicing. For best results, allow the lasagna to cool completely and refrigerate overnight. The next day, reheat at 350 degrees, covered loosely with foil, until bubbling. Remove from heat and rest 20 minutes before serving.
