Creating the sticky goodness of this pasta is straightforward. Follow these detailed steps to ensure success:

1. Cook the Pasta: Begin by boiling a large pot of salted water. Add the fettuccine or spaghetti and cook according to package instructions until al dente. Drain and set aside.

2. Sauté the Sausage: In a large skillet, heat the olive oil over medium heat. Add the sliced sausage and cook until browned, about 5-7 minutes.

3. Add Garlic: Stir in the minced garlic and sauté for another 1-2 minutes until fragrant but not burnt.

4. Prepare the Sauce: In a bowl, whisk together honey, soy sauce, and red pepper flakes if you’re using them. Pour this mixture over the sausage in the skillet.

5. Thicken the Sauce: Allow the mixture to simmer for about 3-4 minutes. Add the cornstarch slurry to the skillet, stirring continuously until the sauce thickens.

6. Combine with Pasta: Add the drained pasta to the skillet, tossing it gently to coat with the sticky honey garlic sauce.

7. Season and Serve: Taste and season with salt and pepper as needed. Remove from heat.

8. Garnish: Top with chopped green onions or parsley for added freshness and presentation.

9. Last Touch: Give everything a final toss to ensure the pasta is evenly coated.
