Meltingly tender cabbage and onions create the sauce for this hearty, full-flavored Northern Italian-inspired pasta. Fontina cheese rounds out the dish with a soft creamy finish. Recipe developed by Food Network Kitchen.
Bring a large pot of salted water to a boil. Add the pasta and cook as the label directs for al dente.
Meanwhile, heat the olive oil in a large skillet over medium-high heat. Add the Canadian bacon and cook until the edges begin to crisp, about 2 minutes. Add the onion and cabbage, season with 1/2 teaspoon salt and a few grinds of pepper and toss to coat. Cook until the vegetables begin to brown and soften, about 3 minutes. Remove 1 cup cooking water from the pasta pot and add to the skillet; bring to a simmer and cook until the cabbage is just tender and the sauce is reduced by about half, 8 to 10 minutes.
Drain the pasta, reserving 1 cup cooking water. Add the pasta and 1/2 cup of the reserved cooking water to the skillet and increase the heat to high; toss to coat, adding more cooking water if the pasta is too dry (it should be very saucy). Stir in the parsley and remove from the heat. Sprinkle with the fontina and parmesan and toss.
