I have four macaroni and cheese recipes that I keep in regular rotation, and this is the most frequently requested of the bunch. It’s also the most labor intensive, so I tend to make it one or twice a year, usually during the holidays. Radicchio is not the most traditional ingredient in baked pasta dishes, but it lends a beautiful light purple hue to the dish and despite all the cheese and other not-so-good-for-you ingredients, you’re getting your vegetables too.
I adapted this dish from a Food and Wine magazine recipe. I use less than half the butter and cream than the original, making it not too unhealthy for a special occasion dish.
1/2 ounce dried porcini mushrooms
2 tablespoons unsalted butter
1 tablespoon extra-virgin olive oil
2 ounces sliced pancetta, cut into 1/2-inch pieces
3 large garlic cloves, minced
2 heads of radicchio, each cut into 8 wedges through the core
Salt and ground pepper
2 teaspoons chopped fresh sage
1 pound medium shell pasta
1/4 cup all-purpose flour
2 cups low-fat milk
1 1/4 cup heavy cream
Pinch of freshly grated nutmeg
1/4 pound Asiago cheese, grated
5 ounces Fontina cheese, grated
1/4 cup freshly grated Parmesan cheese
1. Preheat the oven to 350°. Butter a 3-quart baking dish. In a heatproof bowl, soak the porcini in boiling water until softened, about 15 minutes. Rinse the porcini to dislodge any grit, then drain and chop them. Discard the soaking liquid.
2. In a large skillet, melt 1 tablespoon of the butter in the olive oil. Add the porcini, pancetta and one-third of the garlic and cook over medium-high heat, stirring occasionally, until the garlic is fragrant, about 3 minutes. Using a slotted spoon, transfer to a plate.
3. Add the radicchio wedges to the skillet and cook over high heat until wilted and beginning to brown, about 4 minutes. Add the remaining garlic, season with salt and pepper and cook, stirring, until the radicchio is slightly caramelized, about 5 minutes longer. Stir in the porcini mixture and the sage. Transfer the mixture to a large bowl.
4. Cook the pasta in a large pot of boiling salted water until al dente. Drain. Meanwhile, in a medium saucepan, melt the remaining butter. Add the flour and cook over moderately high heat, stirring, until foamy, about 2 minutes. Gradually whisk in the milk and bring to a boil; cook, whisking until thickened, about 3 minutes. Add the cream and nutmeg and season with salt and pepper. Transfer the sauce to the bowl with the radicchio.
5. Add the pasta to the bowl along with the Asiago and Fontina; toss to combine. Transfer the pasta to the prepared baking dish. Sprinkle with the Parmesan cheese. Bake for 20 minutes, or until heated through.
6. Preheat the broiler. Broil the pasta for 2 minutes, until the top is golden and bubbling. Let stand for 10 minutes; serve.
