Ingredients
Method
- Prep the shrimp. Pat the shrimp dry with paper towels. This helps them sear instead of steam. Lightly season with a pinch of salt and black pepper.
- Make the sauce. In a small bowl, whisk together tamari (or coconut aminos), rice vinegar, sesame oil, broth, fish sauce (if using), and chili paste. If you want a thicker sauce, sprinkle in xanthan gum while whisking to avoid clumps. Set aside.
- Cook the broccoli. Heat 1 tablespoon avocado oil in a large skillet or wok over medium-high heat. Add broccoli and a pinch of salt. Stir-fry for 2–3 minutes, then splash in a tablespoon of water and cover for 1–2 minutes to steam until bright green and crisp-tender. Transfer to a plate.
- Sear the shrimp. In the same pan, add the remaining 1 tablespoon oil. When hot, add shrimp in a single layer. Cook 1–2 minutes per side until pink and just opaque. Do not overcook. Transfer to the plate with broccoli.
- Sauté aromatics. Lower heat slightly. Add garlic and ginger to the pan. Stir for 20–30 seconds until fragrant. Don’t let them brown.
- Bring it together. Return broccoli and shrimp to the pan. Pour in the sauce and toss to coat. Cook 1–2 minutes until the sauce slightly thickens and everything is glossy.
- Finish and serve. Taste and adjust salt, pepper, or heat. Sprinkle with green onions, red pepper flakes, and sesame seeds. Serve hot as is, or over cauliflower rice for a fuller meal.
What Makes This Special
This stir-fry keeps carbs low without sacrificing flavor or satisfaction. The sauce uses keto-friendly swaps to stay bright, savory, and a little sticky, just like the classic.
Shrimp cook fast and absorb flavor quickly, so the dish tastes like it took much longer. Broccoli brings crunch and fiber, and a quick steam-sauté method keeps it vibrant and not mushy. Best of all, the recipe is flexible—add mushrooms, swap oils, or adjust heat without breaking your macros.
What You’ll Need

Keeping It Fresh
Stir-fries shine when they’re cooked fast over high heat.
Keep ingredients prepped and ready before you start cooking. That means shrimp peeled and patted dry, broccoli cut small, and sauce whisked. High heat gives shrimp a nice snap and keeps broccoli crisp.
Leftovers store well in an airtight container for up to 2 days.
Reheat gently in a skillet over medium heat to avoid rubbery shrimp. If the sauce tightens too much, splash in a bit of broth to loosen it. This dish doesn’t freeze well because shrimp can turn tough after thawing.
Benefits of This Recipe
- Low-carb, high-protein: Perfect for keto or low-carb plans without feeling restricted.
- Fast and flexible: From fridge to table in about 20 minutes; easy to scale up for meal prep.
- Nutrient-dense: Broccoli brings fiber, vitamin C, and antioxidants; shrimp is lean and rich in iodine and selenium.
- Restaurant flavor at home: A bold, savory sauce without the sugar found in many takeout versions.
Pitfalls to Watch Out For
- Overcooking shrimp: They go from perfect to rubbery fast.
Pull them as soon as they turn pink and just firm.
- Mushy broccoli: Keep florets small and cook hot and quick. A brief steam helps without losing texture.
- Hidden sugars: Check labels on chili paste, coconut aminos, and broth. Choose unsweetened options.
- Too much xanthan gum: A little goes a long way.
Start with 1/4 to 1/2 teaspoon or skip it if you prefer a lighter sauce.
- Overcrowding the pan: Cook in batches if needed so everything sears instead of steaming.
Alternatives
- Protein swaps: Use chicken thighs, thinly sliced beef, or tofu (if you include soy) with the same sauce. Adjust cook times as needed.
- Vegetable swaps: Try bell peppers, snap peas, zucchini, or mushrooms. Keep total veg to about 4 cups for good sauce coverage.
- Sauce tweaks: Add a squeeze of lime for brightness or a few drops of liquid stevia for a hint of sweetness without carbs.
- Heat levels: Replace chili paste with red pepper flakes or a dash of hot sauce to control the burn.
- Oil options: Avocado oil handles high heat well.
Ghee works too and adds buttery flavor.
- Serve it with: Cauliflower rice, shirataki noodles, or sautéed cabbage for a filling, low-carb base.
FAQ
Can I use frozen shrimp?
Yes. Thaw them in the fridge overnight or run them under cold water in a colander for a few minutes. Pat very dry before cooking to get a good sear and avoid excess moisture in the pan.
Is soy sauce okay on keto?
Traditional soy sauce can be fine in small amounts, but tamari is often lower in carbs and gluten-free.
Coconut aminos are sweeter and slightly higher in carbs, so use sparingly and check the label.
Do I have to use xanthan gum?
No. It’s optional. Without it, the sauce will be lighter but still flavorful.
If you skip it, simmer the sauce for an extra minute to reduce slightly, or add a small pat of butter to help it cling.
How can I meal prep this?
Prep the sauce, cut the broccoli, and peel the shrimp ahead of time. Cook fresh when you’re ready to eat for the best texture. If cooking in advance, undercook the shrimp slightly and reheat gently.
What’s a good substitute for rice vinegar?
Use apple cider vinegar or fresh lime juice.
Start with a smaller amount and add more to taste to keep the acidity balanced.
How do I keep the sauce from getting slimy with xanthan gum?
Sprinkle it in while whisking vigorously, and use the smallest amount needed. If you accidentally add too much, loosen with more broth and cook briefly to even out the texture.
Can I make it nut-free and sesame-free?
Yes. Skip the sesame oil and seeds.
Use avocado or olive oil only, and keep the rest of the ingredients the same. You’ll miss the nutty note, but the garlic and ginger carry the flavor.
How many carbs are in this stir-fry?
Exact numbers vary with brands, but a serving typically lands around 6–8 net carbs without cauliflower rice. Using coconut aminos may bump it up slightly, so measure carefully.
Can I add more vegetables?
Absolutely.
Stick with low-carb options and keep the total volume in check so the pan stays hot and the sauce coats well. You may need to double the sauce if you add a lot more veg.
What pan is best?
A large wok or 12-inch skillet works best. The key is high heat and enough surface area so ingredients sear quickly and don’t steam.
