Warm Introduction
Every now and then, I crave a dish that feels elegant enough to serve at a dinner party but simple enough to make on a busy weeknight. Shrimp scampi has always been one of those “restaurant favorites” for me—the buttery garlic aroma, the tender shrimp, the silky sauce that clings to every bite. The only problem? Traditional scampi is usually served over a big mound of pasta.
When I shifted to a low-carb lifestyle, I thought shrimp scampi would become one of those dishes I’d only order out and never enjoy at home again. But then I discovered the magic of cauliflower rice. By swapping pasta with fluffy, sautéed cauliflower rice, I could still savor all the buttery, garlicky goodness of scampi—without the carb crash.
And let me tell you, Keto Shrimp Scampi over Cauliflower Rice isn’t just a compromise—it’s an upgrade. It’s light yet satisfying, rich but not heavy, and it’s the kind of meal that keeps you energized instead of weighed down.
What Makes This Recipe Stand Out
This recipe isn’t just shrimp tossed in butter—it has layers of flavor and thought behind it. Here’s why it shines:
- Restaurant-Level Taste at Home: It feels gourmet, yet you can whip it up in under 30 minutes.
- Low-Carb & Keto-Friendly: Cauliflower rice replaces pasta while soaking up all the flavors of garlic, butter, and lemon.
- Protein-Packed: Shrimp provides lean protein that’s quick-cooking and naturally keto-friendly.
- Customizable: You can keep it light with lemon and garlic or add a splash of cream for extra indulgence.
- Balanced Nutrition: Instead of just carbs and butter, this dish balances healthy fats, protein, and fiber from cauliflower.
Personal Blogger Note
When I first made this dish at home, I wasn’t sure cauliflower rice could hold up against the rich scampi sauce. But after one bite, I was hooked. The cauliflower rice soaks up the garlicky butter like a sponge, while the shrimp stays juicy and tender. Now, I make this recipe at least twice a month—sometimes for a quick weeknight dinner, sometimes for a “fancy” Friday date-night meal.
Equipment You’ll Need (and Why)
Cooking shrimp scampi doesn’t require a professional kitchen setup, but the right tools make the process smoother:
- Large Skillet or Sauté Pan: Essential for cooking shrimp evenly and giving them a nice sear without crowding. A wide skillet also makes it easy to toss the shrimp in the sauce.
- Sharp Knife & Cutting Board: Prepping garlic, parsley, and lemon requires a reliable knife that doesn’t crush herbs.
- Garlic Press (Optional): If you love bold garlic flavor but hate mincing, a garlic press can save time.
- Zester or Grater: A little lemon zest brightens up the sauce, so having a fine grater is handy.
- Wooden Spoon or Silicone Spatula: Helps stir the sauce without scratching your pan.
- Nonstick or Cast Iron Pan for Cauliflower Rice: Cauliflower rice cooks quickly but can stick—nonstick helps prevent burning.
- Mixing Bowl: Useful if you’re tossing the shrimp with seasonings before cooking.
Ingredients with Substitutions
Every ingredient has its role, but here’s how you can adjust based on what’s in your kitchen:
- Shrimp: Fresh or frozen, peeled and deveined. If you don’t have shrimp, scallops work beautifully.
- Cauliflower Rice: You can buy pre-riced cauliflower or make your own by pulsing florets in a food processor. Broccoli rice or zucchini noodles are good substitutes.
- Butter: Gives the scampi its signature richness. Use ghee or dairy-free butter alternatives if needed.
- Garlic: Fresh is best for bold flavor. Garlic powder works in a pinch, but the depth won’t be the same.
- Olive Oil: Balances butter with a lighter touch of fat. Avocado oil is another great option.
- Lemon Juice + Zest: Brings brightness and cuts through the richness. Lime works if you’re in a pinch.
- Fresh Parsley: Adds freshness at the end. Basil or cilantro can work if you prefer.
- Chicken Broth (Optional): A splash adds depth to the sauce without extra fat. White wine is traditional, but broth keeps it keto-friendly.
- Red Pepper Flakes: Adds a subtle kick. Omit if you prefer mild flavors.
- Salt & Pepper: To season every layer of the dish.
Step-by-Step Cooking Process
Step 1: Prep the Shrimp
Pat the shrimp dry with paper towels—this helps them sear instead of steaming. Lightly season with salt, pepper, and a pinch of red pepper flakes.

Step 2: Sear the Shrimp
Heat butter and olive oil in a large skillet over medium-high heat. Add shrimp in a single layer and cook 1–2 minutes per side until pink and opaque. Remove and set aside—don’t overcook, as they’ll finish in the sauce.

Step 3: Make the Scampi Sauce
In the same skillet, add more butter if needed. Sauté garlic until fragrant, about 30 seconds. Deglaze with chicken broth or a splash of white wine (if you allow it), scraping up brown bits. Stir in lemon juice and zest.
Step 4: Sauté the Cauliflower Rice
In another skillet, heat olive oil. Add cauliflower rice, season lightly, and sauté for 5–7 minutes until tender and fluffy. Keep warm.

Step 5: Bring It All Together
Return shrimp to the skillet with the sauce. Toss gently for 1–2 minutes until heated through and coated. Adjust seasoning to taste.

Step 6: Plate & Serve
Spoon cauliflower rice into bowls or plates, top with shrimp scampi, and finish with fresh parsley and an extra squeeze of lemon.
