How to Make Keto Shrimp Alfredo
Start by heating a large skillet on medium heat.
Add in the butter and olive oil. When the butter has melted, add in the shrimp.
Sauté them for a few minutes, flipping them every few seconds until they are just turning pink, then remove them and set aside.
Add the minced garlic into the butter and olive oil and sauté it for about 20 seconds, careful not to burn it!
Next, just add in the rest of the ingredients and continue cooking while stirring often.
Simmer on low for about 5 minutes or until thickened to your liking. This low carb sauce does not need to cook long at all, that's the beauty of it!
When the sauce is thickened, add the shrimp and cook for about a minute, tossing to coat them well.
You have several choices in ways to serve this. You can serve it over Palmini noodles, zucchini noodles, spaghetti squash or shirataki noodles!
No matter which one you choose, this creamy Keto sauce will steal the show!
I have served this dish several ways and it's always equally scrumptious.
With zoodles, I make them using the OXO Spiralizer. I heat the zoodles for 40 seconds in the microwave, pat them dry and toss in the shrimp and Alfredo sauce.
When using Palmini Pasta noodles, I rinse them really well under cold water for about 5 minutes, then just toss them with the shrimp and Alfredo sauce. I have to say this is my favorite pasta substitute.
They have a texture much like al dente pasta. And the great thing about it is Palmini, or heart of palm pasta, comes in different widths. They gave Palmini Linguini size noodles and they even have Palmini Lasagna sized noodles.
To finish, garnish with a little, or A LOT, of grated parmesan cheese and some freshly chopped parsley!
Tips for Buying Shrimp for Keto Shrimp Alfredo
- Look for fresh, domestic, wild-caught shrimp when available.
- If you have to buy frozen, look at the ingredients. It should just say, "shrimp and water."
- Though jumbo shrimp are my personal favorite, for this recipe, you'll want a pick a medium size, or 31-35 count. This ensures the perfect sauce to shrimp ratio.
- To make this recipe in a jiffy, select shrimp that have are already peeled and deveined. If you can't find them already peeled, look for ones that have been split down the spine. This makes peeling so much easier.
- Don't be afraid to ask to touch and smell the shrimp at your grocery store or fish market. You want to avoid shrimp with a strong "shrimpy," or ammonia-like smell or those with a slimy or soft texture.
