This rich and creamy roasted red pepper sauce is loaded with amazing flavors from red peppers, buttery roasted garlic cloves, Parmesan cheese and fresh basil.
Roasted Red Pepper Sauce
  • 4-5 large red peppers, quartered with stems and seeds removed
  • 2 heads garlic, roasted
  • 2 tablespoons olive oil
  • 1/2 medium onion, diced
  • 2 tablespoons butter
  • 1 cup chicken broth
  • 1/4 cup heavy cream
  • 1/4 cup milk
  • 1/2 cup freshly grated Parmesan cheese
  • 1/4 teaspoon crushed red pepper flakes
  • Salt and pepper, to taste
  • 2 tablespoons fresh basil, sliced into thin strips
  • 16 ounces fresh fettuccine, cooked according to package directions.
  1. Preheat the oven to broil on high. Roast the peppers, skin side up under the broiler for 7-10 minutes or until skins are blackened all around. Remove from the oven and place peppers in a glass bowl and cover tightly with plastic wrap. Let the peppers steam for 30 minutes, then remove the skins with your fingers (they should slip right off). Chop.
  2. Prepare the fettuccine according to package directions in salted water. Drain and toss with a little olive oil.
  3. Heat the olive oil in a large pan over medium-high heat, then sauté the onions in the olive oil until soft. Add the roasted peppers and roasted garlic with the cloves removed from the papery skin, and stir to combine and heat through.
  4. Transfer the contents of the pan to a blender or food processor and puree.
  5. Melt the butter in the same pan. Pour the red pepper puree back into the pan with the butter and add the broth, cream, milk and a pinch of salt and pepper. Stir to combine, then taste and adjust seasonings as needed.
  6. Remove pan from heat and stir in the Parmesan cheese. Add the cooked pasta and gently toss to coat.
  7. Sprinkle with a little additional Parmesan cheese and basil strips and serve immediately.
Recipe Notes
2 heads of garlic might seem like a lot, but roasting garlic really mellows the flavor and it won't be overpowering at all in this sauce.  Here is a tutorial I wrote on how to make roasted garlic at home.  If you don't want to roast the garlic heads, you could just mince up 4 garlic cloves and saute them in with the onions.  Adapted from Yellow Bliss Road.
