Creating Garlicky Black Walnut-Breadcrumb Pasta is straightforward. Just follow these steps for a delicious outcome:

1. Cook the Pasta: Bring a large pot of salted water to a boil. Add the pasta and cook according to package instructions until al dente. Reserve ½ cup of pasta water, then drain the pasta.

2. Toast the Breadcrumbs: In a large skillet, heat 2 tablespoons of olive oil over medium heat. Add the breadcrumbs and toast them, stirring frequently, until golden brown (about 3-4 minutes). Remove from the skillet and set aside.

3. Sauté the Garlic: In the same skillet, add the remaining 2 tablespoons of olive oil. Add minced garlic and sauté until fragrant, about 1 minute, being careful not to burn it.

4. Add the Black Walnuts: Stir in the chopped black walnuts. Cook for 2-3 minutes, allowing the nuts to toast slightly and absorb the garlic flavor.

5. Combine Pasta and Sauce: Add the drained pasta to the skillet with garlic and walnuts. Toss to combine. Add reserved pasta water a little at a time until the pasta is well-coated and reaches your desired consistency.

6. Season: Season with salt, pepper, and red pepper flakes if using. Toss everything until evenly distributed.

7. Top with Breadcrumbs: Finally, stir in the toasted breadcrumbs, reserving a couple of tablespoons for garnish.

8. Serve: Remove from heat, and garnish with chopped parsley and grated Parmesan cheese if desired.

These steps will ensure you create Garlicky Black Walnut-Breadcrumb Pasta effortlessly.
