Ingredients
Method
- Prep the cauliflower rice: If using a whole head, cut into florets and pulse in a food processor until rice-like. Don’t over-process. Pat with a towel to remove excess moisture for better texture.
- Pat the shrimp dry: Moisture is the enemy of a good sear. Dry the shrimp well with paper towels, then season with a pinch of salt and pepper.
- Make the quick sauce: In a small bowl, whisk coconut aminos, rice vinegar, sesame oil, and red pepper flakes or sriracha. Taste and adjust salt if needed.
- Cook the cauliflower rice: Heat 1 tablespoon avocado oil in a large skillet or wok over medium-high heat. Add the white parts of the green onion and sauté 30 seconds. Stir in cauliflower rice with a pinch of salt and pepper. Cook 4–6 minutes, stirring occasionally, until just tender. Transfer to a bowl and cover to keep warm.
- Sear the shrimp: In the same pan, add the remaining 1 tablespoon oil. Increase heat to high. Add shrimp in a single layer and cook 1–2 minutes per side until pink and opaque. Remove to a plate.
- Stir-fry the vegetables: Add bell pepper, zucchini, and snap peas to the hot pan. Stir-fry 3–4 minutes until crisp-tender. If the pan looks dry, splash in a tablespoon of water to create steam without extra oil.
- Add aromatics: Push vegetables to the sides, creating a well. Add garlic and ginger to the center and cook 30 seconds until fragrant, then toss everything together.
- Combine and sauce: Return shrimp and any juices to the pan. Pour in the sauce and toss to coat. Cook 1–2 minutes until the sauce slightly reduces and clings to the shrimp and vegetables. Turn off the heat and fold in the green parts of the green onions.
- Serve: Spoon the shrimp stir fry over warm cauliflower rice. Garnish with sesame seeds and a squeeze of lime, if you like. Taste and add a little more coconut aminos or pepper to finish.
What Makes This Special
This recipe hits that sweet spot between convenient and clean. Shrimp cook in a flash, which means dinner is on the table in under 30 minutes.
Cauliflower rice keeps it low-carb while still giving you that stir-fry feel. The sauce is simple but punchy—garlic, ginger, and a touch of heat make every bite pop. And because it’s flexible, you can swap vegetables or adjust spice without fuss.

Step-by-Step Instructions

How to Store
- Refrigerator: Store leftovers in an airtight container for up to 3 days. Keep the stir fry and cauliflower rice together or separate—either works.
- Reheat: Warm gently in a skillet over medium heat with a splash of water to loosen the sauce. Avoid microwaving for too long, as shrimp can turn rubbery.
- Freezing: Not ideal.
Shrimp and cauliflower can get mushy after thawing. If you must freeze, do it separately and thaw overnight in the fridge before reheating.
Why This is Good for You
- Low in carbs, big on nutrients: Cauliflower delivers fiber, vitamin C, and antioxidants without the starch of regular rice.
- Lean protein: Shrimp is high in protein and low in calories, helping you feel full and satisfied.
- Healthy fats: Using avocado oil and a touch of sesame oil supports a keto-friendly fat profile without heaviness.
- Blood sugar friendly: The combo of non-starchy vegetables and protein supports steady energy.
Common Mistakes to Avoid
- Overcrowding the pan: Too many ingredients at once cause steaming instead of searing. Cook in batches if your pan is small.
- Overcooking shrimp: Shrimp only need a few minutes.
Pull them as soon as they turn pink and curl slightly.
- Soggy cauliflower rice: Pat it dry before cooking and use high heat. Don’t cover the pan, which traps steam.
- Skipping seasoning: Taste as you go. A pinch of salt, a splash more coconut aminos, or a squeeze of lime can make the dish sing.
- Using low heat: Stir fry needs heat.
Medium-high to high gives you color and crisp edges.
Recipe Variations
- Spicy Thai twist: Add a teaspoon of red curry paste to the aromatics and finish with fresh basil and lime.
- Garlic butter shrimp: Swap avocado oil for butter or ghee, increase garlic, and add a splash of lemon instead of vinegar.
- Ginger scallion style: Double the ginger, add extra green onions, and use tamari for a deeper umami note.
- Extra veg: Add mushrooms, baby bok choy, or shredded cabbage. Keep total volume similar so the pan stays hot.
- Nutty crunch: Sprinkle chopped toasted almonds or peanuts on top. For strict keto, use in moderation.
- Sauce swap: Stir in a teaspoon of fish sauce for extra depth, or a dab of sugar-free chili garlic sauce for heat.
FAQ
Can I use frozen shrimp?
Yes.
Thaw completely under cold running water, then pat dry very well. Excess moisture prevents browning and can make the sauce watery.
What if I don’t have coconut aminos?
Use low-sodium tamari or soy sauce. Start with a little less and taste, as both are saltier than coconut aminos.
Can I use pre-riced cauliflower?
Absolutely.
Fresh or frozen both work. If using frozen, thaw and squeeze out extra water with a clean towel for the best texture.
How do I keep the vegetables crisp?
High heat and short cooking time are key. Slice vegetables evenly, don’t overcrowd the pan, and stop cooking when they’re just tender.
Is this recipe dairy-free and gluten-free?
Yes, as written with coconut aminos it’s both dairy-free and gluten-free.
If using tamari, choose a certified gluten-free brand.
Can I make this ahead?
You can prep the vegetables, sauce, and cauliflower rice in advance. Cook the shrimp fresh for the best texture, then toss everything together at the end.
What oil is best for stir-frying?
Use a high-heat oil like avocado, refined coconut, or grapeseed. Save extra-virgin olive oil for finishing, not searing.
