Ingredients

Scale
  • 1 cup roasted red peppers (about 2 large peppers, jarred or homemade, drained and patted dry)
  • 2 tablespoons unsalted butter
  • 3 cloves garlic, minced
  • 1 cup heavy cream
  • 3/4 cup Parmesan cheese, freshly grated
  • 2 ounces cream cheese, softened
  • Salt & black pepper, to taste
  • 12 ounces pasta of choice (such as fettuccine, penne, or linguine; use gluten-free if needed)
  • 1/2 cup pasta cooking water, reserved
  • Fresh basil or parsley (optional, for garnish)

Instructions

  1. Bring a large pot of salted water to a boil. Add pasta and cook according to package directions until al dente (8-10 minutes). Reserve 1/2 cup pasta water, then drain pasta (do not rinse).
  2. While pasta cooks, place roasted red peppers in a blender or food processor and blend until completely smooth.
  3. In a large skillet over medium heat, melt butter. Add minced garlic and sauté for 60–90 seconds until fragrant, but not browned.
  4. Pour pureed peppers into the skillet with garlic. Stir and cook for 1-2 minutes.
  5. Lower heat to medium-low. Add heavy cream and cream cheese, stirring until cream cheese melts and sauce thickens (about 3-5 minutes). Add a splash of reserved pasta water if too thick.
  6. Stir in Parmesan cheese until melted and sauce is silky. Season with salt and black pepper to taste.
  7. Add drained pasta to the skillet and toss well, adding more reserved pasta water as needed until noodles are coated and glossy.
  8. Serve hot, garnished with fresh basil or parsley and extra Parmesan if desired.

Notes

For best results, use freshly grated Parmesan and blend peppers until completely smooth. Reserve pasta water to adjust sauce consistency. Easily adapt for vegan, gluten-free, or low-carb diets. Add protein like chicken, shrimp, or tofu for variation. Sauce thickens as it cools; add a splash of milk or water when reheating.
