Ingredients

  • 12 ounces rigatoni pasta
  • 2 large red bell peppers roasted
  • 1 tablespoon olive oil
  • 1 small onion diced
  • 3 cloves garlic minced
  • 1 cup heavy cream
  • 1 cup grated Parmesan cheese
  • 1 teaspoon Italian seasoning
  • salt and pepper to taste
  • fresh basil leaves for garnish

Instructions

Roast the Red Peppers

  • Preheat your oven to 450°F (230°C). Place whole red bell peppers on a baking sheet and roast for about 25 minutes, turning occasionally until the skin is blistered and charred in spots.
  • Transfer the peppers to a bowl and cover tightly with plastic wrap or a plate to steam off the tough skin. After 10 minutes, peel off the skin, remove seeds, and roughly chop the peppers.

Cook the Rigatoni

  • While the peppers roast, bring a large pot of salted water to a boil. Add the rigatoni and cook according to package instructions until al dente. Reserve about a cup of pasta water, then drain and set aside.

Build the Flavor Base

  • Heat olive oil in a large skillet over medium heat. Add diced onion and sauté until translucent and soft, about 5 minutes. Stir in minced garlic and cook for another minute until fragrant.

Make the Roasted Red Pepper Sauce

  • Transfer the roasted red peppers to a blender or food processor and puree until smooth. Pour the puree into the skillet with onions and garlic.
  • Stir in heavy cream, Italian seasoning, and season with salt and pepper. Let the sauce simmer gently for 5 minutes to meld flavors and thicken slightly.

Combine Pasta and Sauce

  • Add the cooked rigatoni to the skillet with the sauce, tossing gently to coat. If the sauce feels too thick, add reserved pasta water a little at a time until you reach your desired consistency.
  • Sprinkle the grated Parmesan cheese and stir until melted and creamy.

Garnish and Serve

  • Remove from heat and serve immediately, garnished with fresh basil leaves.

Notes

  • Roast the peppers yourself for the best smoky, sweet flavor instead of using jarred ones.
  • Reserve pasta water to adjust sauce consistency without watering down flavor.
  • Use freshly grated Parmesan for a richer, creamier sauce texture.
  • For a dairy-free version, substitute heavy cream with full-fat coconut milk and Parmesan with nutritional yeast or vegan cheese.
  • Reheat leftovers gently with a splash of cream or pasta water to keep the sauce creamy.
