Why This Recipe Works

• Quick cooking time: Shrimp and zucchini both cook fast, so dinner’s done in under 20 minutes.
• Clean ingredients: No heavy thickeners or sugary sauces—just real flavors from garlic, chili, ginger, and lime.
• Balanced texture: Crisp-tender zucchini paired with succulent shrimp keeps the dish light but satisfying.
• Customizable heat: Adjust the spice level easily with chili flakes or sriracha.
• Macros that make sense: High protein from the shrimp, low-carb vegetables, and minimal oil.

Ingredients

• 1 lb (450 g) raw shrimp, peeled and deveined (large or medium work well)
• 2 medium zucchini, halved lengthwise and sliced into half-moons
• 1 red bell pepper, thinly sliced (optional, for color and crunch)
• 3 cloves garlic, minced
• 1-inch piece fresh ginger, peeled and minced (or 1 tsp ground ginger)
• 2 green onions, sliced (white and green parts separated)
• 2 tbsp avocado or olive oil
• 2 tbsp low-sodium soy sauce or tamari (use coconut aminos if paleo)
• 1–2 tsp sriracha or chili-garlic sauce (adjust to taste)
• 1 tsp toasted sesame oil
• 1 tsp rice vinegar or lime juice
• 1/2 tsp red pepper flakes (optional, for extra heat)
• Salt and black pepper, to taste
• Sesame seeds, for garnish (optional)
• Fresh cilantro or basil, chopped, for garnish (optional)

How to Make It

1. Pat the shrimp dry. Moisture is the enemy of a good sear. Use paper towels to dry the shrimp thoroughly, then season lightly with salt and black pepper.
2. Prep the vegetables. Slice zucchini into half-moons and the bell pepper into thin strips.

   Mince garlic and ginger. Separate the white and green parts of the green onions.

3. Make the sauce. In a small bowl, mix soy sauce (or tamari), sriracha, sesame oil, and rice vinegar or lime juice. Taste and adjust heat and salt as needed.
4. Heat the pan until hot. Use a large skillet or wok over medium-high heat.

   Add 1 tablespoon of oil, swirl to coat.

5. Sear the shrimp. Add shrimp in a single layer. Cook 1–2 minutes per side until just opaque and lightly browned. Remove to a plate to prevent overcooking.
6. Stir-fry the veggies. Add the remaining oil to the pan.

   Toss in zucchini, bell pepper, and the white parts of the green onion. Stir-fry 3–4 minutes until crisp-tender. Don’t overcook—the zucchini should still have bite.

7. Add aromatics. Push the vegetables to the sides.

   Add garlic and ginger to the center and cook 30 seconds until fragrant.

8. Combine and sauce. Return shrimp to the pan. Pour in the sauce and sprinkle in red pepper flakes if using. Toss for 30–60 seconds until everything is coated and heated through.
9. Finish and serve. Remove from heat.

   Top with the green parts of the green onions, sesame seeds, and fresh herbs if you like. Serve as-is, over cauliflower rice, or with a small scoop of brown rice if you need more carbs.

How to Store

• Refrigerate: Store leftovers in an airtight container for up to 2 days. Shrimp can get rubbery if reheated too long, so warm gently.
• Reheat: Use a skillet over low to medium heat for 2–3 minutes, just until hot.

  A splash of water or broth helps loosen the sauce.

• Freezing: Not ideal. Zucchini can turn mushy and shrimp dry out when frozen and thawed.
• Meal prep tip: Keep the sauce separate and cook shrimp fresh if possible. Pre-slice veggies for a fast assembly later.

Health Benefits

• High in protein: Shrimp is lean, delivering around 20–24 grams of protein per 3.5 ounces (100 g) with minimal fat.
• Low in carbs: Zucchini and bell pepper keep carbs low while adding fiber and volume, making the meal filling without heaviness.
• Micronutrient-rich: You get vitamin C from peppers and green onions, potassium from zucchini, and selenium, iodine, and B12 from shrimp.
• Anti-inflammatory flavors: Garlic, ginger, and chili bring antioxidants and support digestion.
• Clean cooking method: Stir-frying uses minimal oil and short cooking times, which helps preserve nutrients.

Common Mistakes to Avoid

• Overcrowding the pan: This steams the shrimp and zucchini instead of searing.

  Cook in batches if your pan is small.

• Overcooking the shrimp: Shrimp turn tough fast. Pull them as soon as they’re pink and opaque.
• Skipping the pat-dry step: Excess moisture kills browning and dilutes the sauce.
• Adding sauce too early: Sauce should go in at the end to coat everything without making the veggies soggy.
• Using too low heat: Medium-high heat gives you that quick sear and keeps vegetables crisp-tender.

Alternatives

• Protein swaps: Use chicken breast, thinly sliced beef, or firm tofu. Adjust cooking time as needed.
• Vegetable swaps: Try asparagus, snap peas, mushrooms, or baby broccoli.

  Keep cook times short to maintain crunch.

• Sauce tweaks: Add 1 tsp honey or monk fruit for a touch of sweetness, or a splash of fish sauce for depth.
• Heat variations: Swap sriracha for gochujang, sambal oelek, or crushed Calabrian chiles.
• Low-carb sides: Serve over cauliflower rice, zucchini noodles, or shredded cabbage sautéed with garlic.
• Gluten-free: Use tamari or coconut aminos instead of soy sauce.
• Paleo/Whole30: Go with coconut aminos, skip any added sweeteners, and stick to avocado oil.

FAQ

How spicy is this recipe?

It’s medium-spicy as written. Reduce the sriracha and skip the red pepper flakes for mild heat, or add more to turn it up.

Can I use frozen shrimp?

Yes. Thaw completely in the fridge or under cold running water, then pat very dry before cooking.

Wet shrimp won’t sear well.

What size shrimp should I buy?

Large or medium shrimp (21–30 count per pound) work best. They cook quickly but still have a satisfying bite.

Do I need a wok?

No. A large, heavy skillet works well.

Just make sure it’s hot and don’t crowd the pan.

How do I keep the zucchini from getting mushy?

Cut it into thicker half-moons, cook over medium-high heat, and keep the stir-fry time short. Add the sauce at the end and don’t cover the pan.

Can I make it non-spicy?

Absolutely. Skip the sriracha and chili flakes.

Add extra garlic and a squeeze of lime for brightness.

Is this recipe keto-friendly?

Yes. It’s naturally low in carbs. For strict keto, use tamari or coconut aminos and serve over cauliflower rice.

What’s a good garnish?

Sesame seeds, sliced green onion tops, chopped cilantro, or Thai basil all add freshness and crunch.

Can I add noodles?

If you want a higher-carb option, toss in cooked rice noodles or soba at the end with a little extra sauce.

For low-carb, use shirataki noodles.

How can I meal prep this?

Pre-slice veggies and mix the sauce ahead of time. Cook shrimp fresh for best texture, or cook everything and reheat gently within two days.
