Servings: 4

INGREDIENTS:

• 1 lb Fettucini (green, preferably)
• 2 Onions, thinly sliced
• 2/3 cup Sour cream
• 1/4 cup Oil

• 1 cup Parmesan cheese, grated
• 2 Tbs Butter
• Pepper to taste

INSTRUCTIONS:

1. Cook the fettucini according to the package instructions until al dente. Drain and set aside.
2. If using the microwave method:
   • In a 2-quart microwave-safe bowl, combine oil, sliced onions, and minced garlic.
   • Cook on HIGH (100%) power for 2 minutes. Stir in the walnuts and cook on HIGH for an additional 2 minutes.
   • Stir in grated Parmesan cheese and sour cream. Cook on HIGH for 1 1/2 to 2 minutes, stirring every 30 seconds until the sauce is heated through and well combined.

4. In a separate pan, melt the butter. Toss the cooked fettucini in the melted butter to coat the pasta.

6. Serve immediately, optionally garnishing with extra grated Parmesan cheese and some freshly ground pepper.

Enjoy your delicious creamy fettucini with walnut sauce!

Here are some variations you can try for this creamy fettucini with walnut sauce recipe:

1. Chicken and Mushroom: Add cooked and sliced chicken breast and sautéed mushrooms to the sauce for a heartier version of the dish. Cook the chicken separately, and add it along with the mushrooms when incorporating the sauce.
2. Spinach and Artichoke: Add cooked spinach and chopped artichoke hearts to the sauce for a delicious veggie twist. Sauté the spinach until wilted, and then stir in the artichoke hearts before adding to the sauce.
3. Sun-Dried Tomatoes: Incorporate chopped sun-dried tomatoes for a burst of tangy flavor. Rehydrate the sun-dried tomatoes in warm water before adding them to the sauce.
4. Creamy Pesto: Mix in a few tablespoons of basil pesto to the walnut sauce for a vibrant, herby kick. Adjust the amount of sour cream to achieve the desired consistency.
5. Lemon Zest: Add some grated lemon zest to the sauce to brighten up the flavors and add a citrusy note. Be cautious not to add too much, as lemon can overpower the other flavors.
6. Spicy Kick: Enhance the sauce with red pepper flakes or a dash of cayenne pepper for a spicy version. Adjust the heat level according to your preference.
7. Asparagus and Peas: Include blanched asparagus spears and fresh green peas to the pasta for a fresh and nutritious touch. Stir them in when combining the sauce with the fettucini.
8. Creamy Mushroom: Replace the onions with sautéed mushrooms for a creamier and earthier sauce. Mushrooms add a rich umami flavor to the dish.
9. Bacon and Spinach: Crumble cooked bacon and add it along with the sautéed spinach to the sauce. The combination of bacon and spinach complements the creamy walnut sauce perfectly.
10. Herb-Infused: Infuse the sauce with additional herbs like thyme, rosemary, or sage for added depth of flavor. Simply simmer the herbs in the sauce for a few minutes before serving.
