This easy Keto Shrimp Scampi recipe is ready in just 20 minutes! Serve it up with cauliflower rice or low-carb pasta for one delicious dinner.

This Keto Shrimp Scampi is the 💣 .com. It’s packed with garlic, lemon, olive oil, and Parmesan. This one-pan recipe will quickly become a go-to in your weeknight dinner rotation. You thought 30-minute dinner recipes were great, wait until you try 20 😉

Some shrimp scampi recipes tend to use chicken broth when that luscious sauce should only be made from 4 things:

  1. butter
  2. olive oil
  3. lemon juice
  4. white wine

Adding broth to the scampi is a no-go unless you’re wanting to make this recipe alcohol-free. Then it’s a great swap.

Ingredients in Keto Shrimp Scampi

  • 2 tablespoons extra-virgin olive oil
  • 4 tablespoons unsalted butter (see notes below on how to make it dairy-free)
  • 1/2 medium onion, diced (we like yellow onions here)
  • 4 cloves minced garlic (always fresh, never pre-minced)
  • 1 teaspoon sea salt
  • 1/2 teaspoon freshly ground black pepper (we’re in love with this Diaspora Co. Aranya Pepper)
  • 1/2 teaspoon Italian seasoning
  • 1/2 teaspoon red pepper flakes (optional)
  • Juice and zest of 1 lemon
  • 1 cup dry white wine (such as a pinot grigio)
  • 1 lb shrimp, deveined and peeled  (we like to leave the tails intact)
  • Fresh parsley, for garnish
  • Shaved Parmesan cheese, for garnish (see notes below for dairy-free options)

How to make Keto Shrimp Scampi 

  1. Place the olive oil and butter in a 10″ or larger cast-iron skillet over medium heat. Once hot, add in the onion and cook until soft and translucent, about 3-5 minutes.
  2. Add in the garlic, red pepper flakes, Italian seasoning, and lemon zest and cook until garlic is fragrant, about 30 seconds.
  3. Next, add in white wine and lemon juice, cook to reduce sauce about 5 minutes.
  4. Add in shrimp and cook until they turn pink, about 3 minutes. Season with salt and pepper to taste.
  5. Garnish with parmesan cheese and parsley to serve.

How to make this keto Shrimp Scampi dairy-free

Simple! Swap out the butter for vegan butter, we like Miyokos. Swap the Parmesan cheese for vegan parm, we like Violife!

How to make this recipe paleo and Whole30 compliant

You’ll want to swap out the butter for extra olive oil, nix the Parmesan cheese, and use broth (chicken or veggie works great) in place of the dry white wine.

What sides to serve with shrimp scampi

We love this recipe with spaghetti squash noodles, shirataki noodles, zucchini noodles, cauliflower rice, or mashed cauliflower!

Tools we used in this recipe

  • Cast Iron Skillet [budget option, heirloom splurge option]
  • Citrus Zester
  • Citrus Juicer
  • Cutting Board
  • Chef’s Knife

History of Shrimp Scampi

Shrimp Scampi as you know it wasn’t traditional to Italy. It actually came about as Italian immigrants made their way to the US and adapted American ingredients for their Italian recipes. The fusion of food cultures always starts with migration patterns.

In Italy, traditional Shrimp Scampi was made with, well, Scampi. Scampi are tiny, lobster-like crustaceans also known as langoustines. In the traditional variation of the dish, Scampi were quickly cooked with olive oil and garlic.

Some cooks put a further spin on the dish by adding tomatoes, tarragon, tomatoes, or breadcrumbs. So interesting!

Our version here is most like what you’re probably familiar with here in the US. Next time though we may just add some tomatoes and tarragon and see what happens!

    FYI, it is NOT dairy free if it contains butter and cheese…

      FYI, read the post and you’ll see that there’s an entire section about how to make this recipe dairy-free. Would have been quicker than leaving a rude comment.

These Cauliflower Walnut Taco Cups were originally These Cauliflower Walnut Taco Cups were originally featured in our cookbook and now that Cast Iron Keto is focused on plant-based + low-carb recipes, we thought it deserved a permanent place on the website.⁠
⁠
If you have our cookbook, have you tried this recipe out of the Meatless Monday chapter? If not, we hope you do, even if you’re more omnivore than plant-based. Why? Because they are simply delicious!⁠
⁠
The combination of the crumbled walnuts, tender cauliflower, and smoky chipotle peppers in adobo sauce create a filling that, while it resembles ground beef, is much more layered in flavors.⁠
⁠
The toppings are completely up to you, these are just our go-to’s. Some type of creamy sauce would be delicious too. Maybe a bit of dairy-free (or regular) sour cream mixed with a bit of extra chipotle in adobo? Yes, that sounds just perfect. You can grab the recipe link in our bio!⁠
