Ingredients

Cashew Cream

  • 1 cup raw cashews
  • ½ cup water (for blending)
  • ¼ teaspoon salt

Pasta

  • 16 ounces rigatoni (or your preferred pasta)
  • ¾ teaspoon salt (divided)

Sauce

  • 2 tablespoons olive oil
  • 1 yellow onion, finely chopped
  • 4 garlic cloves, minced
  • ¼ cup tomato paste
  • 1 (15-ounce) can diced tomatoes
  • ¼ teaspoon crushed red pepper flakes

Instructions

  1. Prepare the Cashew Cream: Place the raw cashews in a small bowl and cover with boiling water. Let them soak for about 60 minutes until tender. Once soft, drain the cashews and transfer them to a blender with ½ cup of fresh water and ¼ teaspoon salt. Blend until smooth and creamy. Set aside.
  2. Cook the Pasta: Bring a large pot of heavily salted water to a boil. Add the rigatoni and cook according to package instructions, but reduce the cooking time by 2-3 minutes to keep the pasta al dente. Reserve 1 ½ cups of pasta cooking water before draining the pasta.
  3. Prepare the Sauce: Heat the olive oil in a large pan over medium heat. Add the chopped onion and cook until softened, about 3-4 minutes. Add the minced garlic and cook until fragrant, about 1 minute. Stir in the tomato paste and cook, stirring constantly, until it darkens, about 2 minutes. Add the diced tomatoes, crushed red pepper flakes, remaining ½ teaspoon salt, and ½ cup of reserved pasta water. Simmer the sauce until it thickens and deepens in color, about 10 minutes.
  4. Combine Pasta and Sauce: Add the cooked pasta, cashew cream, and remaining 1 cup of pasta water to the sauce. Toss thoroughly to coat the pasta with the sauce evenly.
  5. Serve: Garnish with fresh basil leaves if desired and serve immediately for best flavor and texture.

Notes

  • Soaking cashews overnight can reduce the soaking time and produce an even creamier texture.
  • Reserve pasta water carefully; it’s key for achieving the perfect sauce consistency.
  • You can use gluten-free pasta to make the recipe gluten-free.
  • Add fresh basil or parsley as a garnish for added flavor and color.
  • Adjust crushed red pepper flakes according to your preferred level of spice.
