This is an adaptation of my favorite bolognese sauce by Marcella Hazan. There is no better pairing than lamb and rosemary! —Nancy Jo
Test Kitchen Notes
The shiitakes infuse the ragu and your kitchen with a pleasant aroma of wood and earth. Lamb and shiitakes are a lovely and unexpected flavor combination for a sauce, but we think it's the white wine that makes this dish. Red wine, the typical braising liquid for lamb, would have made the sauce seem overwrought and heavy. White wine adds the right acidity and keeps the other flavors nimble yet pronounced. - A&M —The Editors
finely chopped carrot
finely chopped celery
shiitake mushrooms, trimmed and finely sliced
In a medium, heavy saucepan or braising pan, melt 3 tablespoons of the butter and the olive oil over medium-high heat. Add the onion and cook until translucent, adjusting heat so the onion doesn't burn. Add the carrot, celery, mushrooms and rosemary. Season with salt and pepper, and cook, stirring occasionally until the mushrooms are tender, 5 to 10 minutes.
Add the lamb, breaking up the pieces with a spoon, and cook through. Add the wine and cook at a rapid simmer until the liquid is nearly gone, about20 minutes. Add the tomatoes, chopping them with a spoon. Season with salt and pepper, and simmer gently until the sauce has thickened, about 30 minutes.
Bring a large pot of generously salted water to a boil. Add the pasta and cook until al dente. Drain, return the pan and stir in the remaining tablespoon of butter. Stir in the lamb ragu. Divide among 4 large, shallow bowls, and sprinkle with cheese and pepper.
