Creating Garlicky Black Walnut-Breadcrumb Pasta is straightforward when you follow these steps:

1. Cook Pasta: In a large pot, bring salted water to a boil. Cook the pasta according to package instructions until al dente, then drain and set aside.
2. Toast Walnuts: In a skillet over medium heat, toast the chopped black walnuts for about 3-4 minutes until fragrant. Stir often to prevent burning, then remove from the pan and set aside.
3. Prepare Breadcrumbs: In the same skillet, add 2 tablespoons of olive oil. Add the breadcrumbs and toast until golden brown, stirring frequently for 4-5 minutes. Transfer to a bowl and set aside.
4. Sauté Garlic: Using the remaining olive oil, add minced garlic to the skillet. Sauté for 1-2 minutes until fragrant but not browned.
5. Combine Pasta and Sauce: Add the cooked pasta to the skillet with the garlic. Toss to coat the pasta in oil and garlic evenly.
6. Add Ingredients: Stir in the toasted walnuts and red pepper flakes (if using). Season with salt and pepper to taste, mixing everything thoroughly.
7. Garnish: Remove from heat, and add the toasted breadcrumbs on top. Garnish with chopped parsley for freshness.
8. Serve: Plate the pasta and offer grated Parmesan cheese on the side for those who enjoy it.
