Fit It to Your Goals

This 30-Minute Sriracha Pepper Steak is not only delicious but can also be tailored to fit various dietary preferences:
- For a low-carb option, serve it over sautéed zucchini noodles instead of rice.
- To add more veggies, include snap peas or broccoli in the stir-fry.
- For a vegetarian version, substitute the flank steak with tofu or tempeh.
- Adjust the level of sriracha to suit your spice tolerance; less for a milder dish, more for a fiery kick.
Slip-Ups to Skip
While making this dish, there are a few common pitfalls to avoid:
- Don’t overcook the flank steak; it should remain tender and juicy.
- Be careful with the sriracha; start with less if you’re unsure of the heat level.
- Ensure your pan is hot enough before adding the steak to get a good sear.
- Do not skip the cornstarch; it’s essential for thickening the sauce.
Prep Ahead & Store
This recipe is perfect for meal prep! Here’s how you can make it easier for busy weeks:
Chop all your vegetables in advance and store them in airtight containers in the fridge. You can also marinate the steak overnight in the sauce for deeper flavor. The cooked 30-Minute Sriracha Pepper Steak can be stored in the refrigerator for up to three days. Reheat gently on the stove or in the microwave, and serve over fresh rice or grain.
Helpful Q&A
Can I use a different cut of beef?
Yes, you can use sirloin or skirt steak if flank steak is unavailable. Just ensure it is sliced thinly for quick cooking.
What can I substitute for soy sauce?
If you’re looking for a gluten-free option, tamari is a great substitute for soy sauce. Coconut aminos can also work well for a slightly different flavor profile.
How spicy is this dish?
The level of spiciness depends on how much sriracha you use. Start with the recommended amount and adjust according to your taste preferences.
Can I make this vegetarian?
Absolutely! Replace the flank steak with firm tofu or tempeh, and adjust the cooking time accordingly.
