Keto Alfredo Sauce for When You Miss Those Carbs

Pasta has never been one of my favorite foods, but boy, could I put down a lot of it when given the chance! My biggest weaknesses have always been cereal and any bread or roll I could lather up with butter, but as mentioned in a previous post by Matthew, we have mastered The Best Keto Bread on the Internet so we no longer miss it. However, for some reason I find myself missing pasta more than ever, and when I miss something I must recreate it keto-style which is exactly what we did. We present to you our Low Carb Fettuccine Alfredo with Blackened Shrimp and you won’t be disappointed with this rich and creamy keto alfredo sauce.

Keto Alfredo Sauce and Blackened Shrimp: The Ultimate Duet

Normally, Matthew and I collaborate on the entire dish – spoons and forks flying, spices spilling, feet stepping on other feet (human and cat). It’s like a beautiful dance! But, this time we decided to compose the dish more like a duet. I performed the Keto Alfredo sauce and Matthew performed the blackened shrimp, and it worked just as beautifully!  

Performer One: Keto Alfredo Sauce 

I began the performance by pulling out the essential ingredients I would need for a traditional Alfredo sauce:

  • Cream Cheese
  • Butter
  • Heavy Whipping Cream
  • Parmesan Cheese
  • Garlic Powder
  • Salt and Pepper

I wanted traditional because I hadn’t had a good Alfredo sauce in a while and the subtly of a traditional sauce would play the perfect pairing with the heavily seasoned blackened shrimp! In any musical composition, it’s important to know who will be performing by your side so you can work your own strengths as well as the strengths of the second performer! I not only knew the second performer well, but I also knew how he worked in the kitchen and what he had planned for the shrimp, and this made my job a whole lot easier.

I added the ingredients to the saucepan one-by-one allowing each to incorporate into one another and tasting several times along the way. It’s always important to taste your dishes prior to serving, especially sauces because they will likely be the centerpiece of your dish coating everything in sight! After letting the sauce reduce down, I had achieved perfection! I turned the heat down to simmer and patiently watched Matthew’s performance.  

Performer Two: Blackened Shrimp 

Just like in any great duet, Matthew had already begun putting together the seasoning for the shrimp while I was perfecting the sauce. He opted to use:

  • Paprika
  • Garlic Powder
  • Onion Powder
  • Thyme
  • Cayenne
  • Salt and Pepper

He coated the shrimp generously in the seasoning and placed them in a heated skillet as I continued to stir the Alfredo sauce. We were in perfect harmony at that moment. Several minutes had passed and the shrimp seared up and “blackened” just the right amount. We knew it would not only taste incredible, but would make for the perfect photograph.

The Perfect Composition

The two main parts had been completed and set aside. We knew we couldn’t use pasta, but we needed something that would give us the pasta feel. If you haven’t discovered the zero-carb, zero-calorie noodle you’ve been missing out! There are multiple brands, but we used Miracle Noodles for this dish.

First, we rinsed and dried the noodles on paper towels. Second, we heated them in a pan for about 5-7 minutes to dry out them even further. The instructions on the package don’t call for the second step we took, but we highly recommend it for these noodles. It helps to lose their jelly like consistency and odd smell. After they were completely dried out, we coated them in the Keto Alfredo sauce. It was glorious! We ended the performance by placing the blackened shrimp on the noodles and garnishing with parsley. All that was left to do was eat and enjoy!

Our Fettuccine Alfredo with Blackened Shrimp uses zero carb, zero calorie noodles for a perfect ketogenic meal!
