How to Make Old Spaghetti Factory Original Clam Sauce

  1. Melt butter in a large saucepan over medium-low heat. Add minced garlic, chopped onion, and celery.
  2. Cook, stirring occasionally, until the vegetables are softened but not browned (about 5-7 minutes).
  3. Sprinkle in the flour and whisk constantly for 1-2 minutes to create a smooth roux.
  4. In a separate pot, steam or boil clams until they open. Discard any that do not open. Remove clams from their shells, reserving the clam juice.
  5. In a separate saucepan, combine the reserved clam juice, half-and-half, thyme, and salt. Heat over medium heat until it is just simmering.
  6. Gradually whisk the warm clam juice mixture into the roux, stirring constantly until the sauce thickens to your desired consistency (about 2-3 minutes).
  7. Gently stir in the cooked clams.
  8. Cook for another minute to heat through. Taste and adjust seasoning as needed.
  9. Meanwhile, cook pasta according to package directions.
  10. Serve the delicious clam sauce over your cooked pasta. Garnish with extra thyme or chopped parsley, if desired.
