Tools & Kitchen Gadgets Used
This is a one-pan wonder that cooks quickly, so you need a good pan and quick access to your ingredients.
- Large Skillet: Cast iron or stainless steel works best. You need high heat and plenty of surface area.
- Tongs: Essential for quickly flipping and removing the shrimp.
- Chef’s Knife and Cutting Board: For mincing the garlic and chopping the parsley.
- Citrus Juicer: To get the maximum amount of fresh lemon juice.
- Zoodler/Spiralizer (Optional): If you are making fresh zucchini noodles.
Step-by-Step Instructions
Shrimp cooking is a race against the clock. Read these steps first, then execute quickly!
1. Prep the Shrimp
Pat the shrimp very dry with paper towels. This ensures they sear beautifully instead of steaming. Season them lightly with salt and pepper.
2. Sauté the Aromatics
Melt the butter and olive oil in your large skillet over medium heat. Add the shallots (or onion) and sauté for about 2 minutes until soft. Now, add the minced garlic and red pepper flakes. Cook for about 30-60 seconds until fragrant. Watch the garlic closely! Burnt garlic is a sin.
3. Sear the Shrimp
Increase the heat to medium-high. Add the shrimp to the skillet in a single layer. Sear for 1-2 minutes per side until they just start to turn pink and opaque. Do not overcook! Overcooked shrimp is rubbery and sad.
4. Build the Sauce
Remove the shrimp from the pan and set it aside on a warm plate. Reduce the heat. Pour the white wine (if using) into the pan and scrape up any browned bits (the fond). Let it simmer for 30 seconds. Now, pour in the chicken broth and fresh lemon juice. Let it simmer gently for 1 minute to reduce slightly and concentrate the flavors.
5. Combine and Finish
Return the shrimp to the pan. Toss them gently in the sauce to coat and heat through (this should take less than 30 seconds). Remove the pan from the heat. Stir in the fresh parsley and a dusting of Parmesan cheese.
6. Serve Immediately
Serve the keto shrimp scampi directly over your favorite low-carb base (zoodles or spaghetti squash). Drizzle extra sauce over the top and garnish with more parsley. You just made a high-end dinner in minutes.
Calories & Nutritional Info

- Calories: ~350 kcal per serving
- Protein: Very high (over 30g), excellent for satiety.

- Omega-3s: Good source from the shrimp.
- Gluten-Free: Naturally gluten-free.
Common Mistakes to Avoid
Scampi is a delicate dish. Precision and speed are your friends!
- Overcooking the Shrimp: Shrimp cooks fast! The minute they curl into a C-shape and turn pink, they are done. Overcooked shrimp becomes tough and chewy.
- Burning the Garlic: High heat and long cooking times incinerate garlic. Add the garlic last and cook for less than a minute.
- Not Drying the Shrimp: If the shrimp is wet, it steams instead of searing, resulting in a soggy texture. Pat them dry aggressively.
- Skipping the Acid: The lemon juice cuts through the richness of the butter and is essential for that signature “scampi” flavor. Don’t forget the fresh lemon!
- Overcrowding the Pan: This cools the pan down instantly and prevents searing. Cook the shrimp in a single layer, or work in two separate batches.
Variations & Customizations
This classic sauce can be easily adapted to your spice and flavor preferences.
The Creamy Upgrade
Stir in 2 tablespoons of heavy cream right before you add the shrimp back to the sauce (Step 5). This makes the sauce richer and even more decadent, while keeping it keto.
The Spicy Chili Kick
Add an extra 1/2 teaspoon of red pepper flakes and a small splash of chili oil to the butter/oil mixture at the beginning. You can also toss in a finely diced serrano pepper with the garlic.
The Pesto Twist
Stir in 1 tablespoon of sugar-free pesto along with the lemon juice and broth. This adds a fresh, herbaceous, and nutty dimension. Skip the dried herbs if you choose this route.
FAQ Section
What is the best low-carb noodle to serve with scampi? Zucchini noodles (zoodles) are the most common and absorb the sauce well. Spaghetti squash or shirataki noodles are also great keto-friendly options.
Can I make this dairy-free? Yes. Replace the butter with additional olive oil and skip the Parmesan cheese. The sauce will still be rich and delicious thanks to the EVOO and garlic.
Can I use pre-cooked shrimp? You can, but I don’t recommend it. Pre-cooked shrimp often turns rubbery when reheated. If you must, add them only at the very end (Step 5) to warm through for less than 30 seconds.
Is white wine safe for keto? Dry white wines (like Pinot Grigio or Sauvignon Blanc) used for cooking burn off the alcohol and most of the trace carbs. The resulting flavor depth is worth the minimal carb content, but you can substitute with extra chicken broth if you prefer.
How do I prevent the sauce from separating? Sauce separation is usually caused by excessive boiling after adding the fat (butter). Keep the heat medium-low when adding the broth and lemon juice, and don’t let it reduce too much.
How long does keto shrimp scampi last in the fridge? Shrimp is best eaten fresh. Leftovers can be stored in the fridge for 1-2 days, but the shrimp texture degrades quickly.
What is the difference between shrimp scampi and garlic shrimp? Scampi specifically refers to the sauce: butter, white wine, garlic, and lemon. Garlic shrimp is a broader term, but the core flavors are the same. This keto version focuses on maximizing those signature scampi flavors.
Final Thoughts
You just pulled off an incredible keto shrimp scampi dinner in under 20 minutes! You created a low-carb, high-fat feast that tastes straight out of a fancy Italian restaurant.
