Ingredients You’ll Need

Save

For the stir-fry:

• 1 lb (450 g) raw shrimp, peeled and deveined
• 2 tbsp avocado oil (or olive oil)
• 2 cups broccoli florets
• 1 small red bell pepper, sliced thin
• 1 medium zucchini, halved and sliced
• 1 cup sliced mushrooms
• 2 green onions, sliced (whites and greens separated)

For the garlic sauce:

• 4 cloves garlic, minced (yes, four—don’t be shy)
• 2 tbsp soy sauce or tamari
• 1 tbsp oyster sauce (look for a lower-sugar brand) or fish sauce for extra punch
• 1 tbsp rice vinegar
• 1 tsp toasted sesame oil
• 1/2 tsp red pepper flakes (optional, but recommended)
• 1/4 cup chicken broth
• 1/2 tsp xanthan gum OR 1 tsp glucomannan (optional, for light thickening)

Garnish:

• Sesame seeds
• Lime wedges
• Extra green onion greens

Prep Like You Mean It

You’ll cook this fast, so get everything chopped and measured first. Shrimp need to be dry—pat them down so they sear instead of steam. Mix the sauce in a small bowl so you can pour it in at the perfect moment without scrambling for soy sauce like it’s a game show.

Sauce Notes (Because Details Matter)

– Want a glossy finish without carbs? Use a pinch of xanthan gum. Sprinkle it into the cold sauce and whisk hard to avoid clumps.
– No thickener? Skip it. The sauce still rocks—just a touch lighter.
– Gluten-free? Use tamari or coconut aminos (but note coconut aminos add a few extra carbs).

How to Cook It (Fast and Flavorful)

Save

1. Make the sauce: In a bowl, whisk soy/tamari, oyster sauce, rice vinegar, sesame oil, broth, red pepper flakes, and garlic. Add xanthan gum if using and whisk smooth.
2. Sear the shrimp: Heat 1 tbsp oil in a large skillet or wok over medium-high. Season shrimp with a pinch of salt and pepper. Cook 1–2 minutes per side until just opaque. Remove to a plate.
3. Stir-fry veggies: Add remaining oil. Toss in broccoli and mushrooms first; cook 2–3 minutes. Add bell pepper, zucchini, and the white parts of green onion; cook another 2–3 minutes until crisp-tender.
4. Sauce it up: Return shrimp to the pan. Pour in the sauce and toss. Cook 1–2 minutes until everything’s glossy and the garlic smells outrageous.
5. Finish: Kill the heat. Sprinkle sesame seeds and green onion greens. Squeeze lime over the top. Taste and adjust salt, heat, or acidity. Serve immediately.

Make It Your Own

You’ve got options, and IMO that’s the best part of stir-fry life.

Veggie Swaps (Low-Carb All-Stars)

• Snow peas (in moderation), bok choy, cabbage, or asparagus
• Cauliflower rice on the side for a legit “takeout” moment
• Spinach at the end for extra greens without extra carbs

Protein Tweaks

• Swap shrimp for thin-sliced chicken thighs or beef sirloin
• Add a whisked egg at the end for extra richness (stir fast so it ribbons)

Flavor Boosts

• Grate fresh ginger with the garlic for zing
• Add a few drops of chili oil if you like it hot
• Finish with a pat of butter for a silky sauce (FYI: not traditional, but delicious)

Pro Tips for Searing Shrimp Like a Boss

Save

– Dry shrimp = better sear. Water ruins browning.
– Don’t crowd the pan. If needed, cook in batches.
– High heat, short time. Overcooked shrimp turn rubbery faster than you can say “why.”
– Season lightly. The sauce brings major umami—no need to salt-bomb early.

FAQ

Can I use frozen shrimp?

Absolutely. Thaw them in the fridge overnight or under cold running water for 10–15 minutes. Pat them very dry before cooking so they sear instead of steaming. Pro move: remove excess moisture with a paper towel and a quick air-dry in the fridge for 10 minutes.

What can I use instead of oyster sauce to keep carbs even lower?

Use fish sauce plus a pinch of your favorite keto sweetener to balance the saltiness. It gives you a deep umami punch with fewer carbs. Start with 1–2 teaspoons fish sauce and adjust to taste.

Do I need a wok?

Nope. A large stainless or cast-iron skillet works great. Heat it properly and don’t crowd it—those two things matter more than the shape of your pan, IMO.

How do I prevent soggy veggies?

Cook hot and fast, and stagger the veggies by density. Broccoli and mushrooms first, then bell pepper and zucchini. Don’t cover the pan—steam is the enemy of crisp.

Is xanthan gum required?

Not at all. It just gives the sauce a glossy, clingy vibe. If you skip it, the dish still slaps—just a little looser in texture. Sprinkle, whisk, and use a tiny amount if you do include it.

How spicy is this?

Mild with the suggested red pepper flakes. Bump it up with chili oil or fresh sliced chiles if you like heat, or skip them if your taste buds prefer peace and quiet.
