Heat the oven to 375°F and arrange a rack in the middle. Spread 2 cups of the Bolognese sauce in a thin layer over the bottom of a 13-by-9-inch baking dish.
Construct the lasagna by layering 4 noodles over the sauce. Top with another 2 cups Bolognese sauce and spread it evenly to the edges of the dish; cover with 1/4 (3 ounces) of the sliced provolone cheese. Spread 1 cup of the béchamel sauce in a thin layer and top with 1/4 cup of the grated Parmigiano-Reggiano cheese.
Place the next layer of lasagna noodles perpendicular to the direction of the first layer and top with another layer of filling (using the same amounts of ingredients as above). Repeat 2 more times, being sure to place each layer of lasagna noodles perpendicular to the previous layer.
Cover the dish tightly with aluminum foil. Place on the center rack of the oven and bake for 40 minutes or until the cheese is melted and bubbling. Remove the foil and continue baking until the edges are brown and the noodles are completely tender, about 20 minutes more. Allow to stand for 20 to 30 minutes before slicing.
Beverage pairing:Fattoria Zerbina Torre di Ceparano Sangiovese di Romagna, Italy. It’s always safe to go for Italian wine with Italian food, especially wine from the same region as the dish. This light, elegant, and perky Sangiovese vibrates with tart cherry, coffee, and minty notes, and will be a refreshing partner for the lasagna. If you can’t find Sangiovese di Romagna, then a Chianti or Rosso di Montalcino (both Sangiovese-based) will do nicely.
