Low Carb Fettuccine Pasta

Creating low-carb fettuccine pasta that is healthy, satisfying, and delicious is easier than you think. Below, we’ll guide you through a step-by-step process to prepare a keto-friendly pasta dish using simple yet effective alternatives.

Ingredients

• Protein Pasta Noodles: 1 (8 oz) package.

• Fresh Parsley: 1 tablespoon, finely chopped, for garnish.

Ingredients for Alfredo Sauce

• 2 tablespoons butter

• 4 ounces cream cheese (softened for easier melting)

• 1 cup heavy whipping cream

• 1 cup grated Parmesan cheese (freshly grated for optimal flavor and texture)

• 1/2 teaspoon garlic powder

• Salt and pepper to taste

Instructions

1. Prepare the Protein Noodles

Cook the protein-rich pasta noodles according to the instructions on the package. Set aside.

2. Create the Creamy Sauce

Heat a small saucepan over low heat. Add the butter and cream cheese. Stir continuously until completely smooth and well combined. Slowly pour in the heavy whipping cream while stirring to create a cohesive base. Gradually mix in the grated Parmesan, allowing it to melt and thicken the sauce. The Parmesan is key for a truly creamy texture and authentic flavor.

Sprinkle in garlic powder, then season with salt and freshly cracked pepper. Adjust to your taste preferences.

If the sauce isn’t thick enough, add more Parmesan cheese or a tiny pinch of xanthan gum while stirring to avoid clumping. Allow the sauce to rest off heat for a minute. It will thicken further as it cools.

3. Combine Noodles with Sauce

Add the cooked pasta noodles to the skillet. Toss them in the sauce until evenly coated. Cook for an additional 1-2 minutes, allowing the flavors to meld together.

4. Serve and Garnish

Transfer the low-carb fettuccine pasta to a plate or bowl. Garnish with freshly chopped parsley and an extra sprinkle of Parmesan for an authentic Italian-inspired touch.

This low carb fettuccine recipe delivers all the satisfying textures and creamy flavors of traditional pasta dishes without the carb overload. Perfect for keto dieters and health-conscious individuals, it’s a simple way to enjoy low-carb Italian pasta in under 15 minutes.

How do you store Alfredo Sauce?

Storing Alfredo sauce correctly ensures its creamy texture and flavorful taste remain intact. Whether you're prepping it ahead of time or saving leftovers, follow these simple steps:

1. Refrigeration: Transfer the cooled sauce into Mason jars or airtight glass containers. This helps preserve its freshness and prevents the sauce from absorbing other fridge odors. Store in the refrigerator for up to one week.

2. Freezing: Alfredo sauce freezes well but should be frozen separately from any low-carb pasta, such as keto fettuccine noodles or shirataki fettuccine. Pour the sauce into freezer-safe containers, leaving a small gap at the top for expansion. Store for up to 3 months.

3. Thawing: To revive frozen sauce, transfer it from the freezer to the refrigerator the night before use. Allow it to thaw naturally to maintain its smooth consistency.

4. Reheating: Gently reheat on the stovetop over low heat, stirring continuously to prevent separation. If the sauce has thickened, add a splash of heavy cream to bring back the original creamy texture.

When paired with zucchini fettuccine noodles, egg-based fettuccine, or other low-carb options, properly stored Alfredo sauce retains its rich flavor, ensuring indulgent low-carb fettuccine pasta dishes any day of the week.

Can you freeze Alfredo Sauce?

Yes, you can freeze Alfredo sauce for later use, making it an excellent option for meal prep with our low-carb fettuccine pasta. To freeze Alfredo sauce, ensure it’s completely cooled to preserve its creamy texture and flavor. Place the sauce in an airtight container, like Mason jars or glass containers, leaving some space at the top to allow for expansion during freezing. Properly stored, Alfredo sauce can last up to three months in the freezer.

When you’re ready to use it, transfer the frozen Alfredo sauce to the refrigerator the night before and let it thaw naturally. Once thawed, reheat the sauce gently on low heat, stirring frequently to prevent separation. For extra smoothness, consider blending the reheated sauce before serving. We recommend freezing the sauce separately from keto fettuccine noodles or any other low-carb pasta to maintain the best texture and flavor for your dishes.
