I don’t care much for the boxed lasange noodles you find in the market – you know, the ones with the curly edges. Makes for an unpleasant thick bite of pasta, when lasagne really calls out for thin supple sheets of fresh pasta. But if you can’t spend a whole afternoon making fresh pasta, the no-boil Barilla noodles are a good substitute. Don't skimp on the meat sauce, as the no-boil pasta sheets need to absorb a lot of liquid. —mrslarkin
For béchamel sauce, over medium-low heat, melt butter in a saucepan.
Add the flour and stir with a spoon until bubbly. Don’t burn it! Lower heat if needed. You just want to cook some of the raw taste out of the flour.
Stir in milk until thickened, about 5 minutes or so. Using a small fine-mesh strainer, scoop up any lumps and press through with a wooden spoon. Season with salt and nutmeg. Set aside.
For lasagne, in a 9” x 13“ baking pan, spread 1 ½ cups of bolognese sauce on bottom of pan. Layer 4 overlapping sheets, 1 generous cup bolognese sauce, 1 cup béchamel and ¾ cup Parmigiano. Repeat 3 more times with remaining layers. Top with extra grated Parmigiano if desired.
Cover tightly with foil and bake for 50 minutes. Uncover and continue baking 5 minutes. Remove from oven and let rest for 10 to 15 minutes.
