Rigatoni with Red Peppers, Wild Mushrooms, and Fontina Recipe

  • 2 tablespoons olive oil
  • 2 large red onions, halved lengthwise, cut crosswise into 1/3-inch-thick slices (about 6 cups)
  • 1 pound assorted wild mushrooms (such as small portobello, oyster, chanterelle, and stemmed shiitake), cut into 1/3-inch-thick slices (about 10 cups)
  • 2 large red bell peppers, cut lengthwise into 1/3-inch-thick strips (about 4 cups)
  • 1 pound rigatoni
  • 3 teaspoons marjoram, divided
  • 1 1/2 cups grated Fontina cheese (about 6 ounces), divided
  1. Heat oil in heavy large pot over high heat. Add onions and cook until soft and beginning to brown, stirring frequently, about 8 minutes. Reduce heat to medium-high. Add mushrooms and sauté until wilted, about 3 minutes. Add peppers and sauté until just soft, about 5 minutes longer.
  2. Meanwhile, cook pasta in large pot of boiling salted water until tender but still firm to bite, stirring occasionally. Drain, reserving 1 cup cooking liquid.
  3. Add reserved pasta cooking liquid and 2 teaspoons marjoram to skillet and stir, scraping up browned bits. Add drained pasta to sauce and toss to coat. Add 1 cup cheese; stir until melted. Transfer pasta to large bowl; sprinkle with remaining 1/2 cup cheese and 1 teaspoon marjoram.
