Follow these steps for a flawless King Crab Pasta With Tomato and Ouzo Sauce:

1. Cook the Pasta: Bring a large pot of salted water to a boil. Add linguine or spaghetti and cook according to package instructions until al dente. Drain and reserve about 1 cup of pasta water.

2. Sauté Aromatics: In a large skillet, heat olive oil over medium heat. Add chopped onion and sauté until translucent, about 3-5 minutes. Add minced garlic and red pepper flakes, cooking for an additional minute.

3. Add Tomatoes: Stir in the diced tomatoes, cooking for another 5 minutes. Allow the flavors to meld.

4. Deglaze with Ouzo: Pour in the ouzo, scraping any brown bits from the bottom of the skillet. Let it simmer for 3-4 minutes to cook off some of the alcohol.

5. Add King Crab: Gently fold in the king crab meat, letting it warm through without breaking the meat too much.

6. Combine Pasta: Add the cooked pasta to the skillet, tossing to combine. If the mixture is too dry, gradually add reserved pasta water until the desired consistency is reached.

7. Season: Add lemon zest, lemon juice, salt, and pepper to taste. Stir in chopped parsley for an extra burst of flavor.

8. Serve: Plate the pasta in shallow bowls. If desired, top with grated Parmesan cheese.
