Ingredients
- Beef top sirloin steak: Quality matters here as it stays tender with quick cooking
- Fresh gingerroot: Provides that unmistakable warm spicy note that defines great Asian cuisine
- Garlic cloves: The aromatic foundation that builds depth in the dish
- Coconut milk: Creates a silky sauce that balances the heat beautifully
- Sriracha chili sauce: Adds controlled heat that builds rather than overwhelms
- Lime zest and juice: Brightens everything with citrus notes that cut through the richness
- Red pepper and onion: Add sweetness color and satisfying crunch
- Jalapeno: Brings fresh heat that complements the Sriracha
- Baby spinach: Wilts perfectly into the sauce adding nutrition and color
- Fresh cilantro: Adds that final pop of herbaceous brightness
Step-by-Step Instructions
- Marinate the Beef:
- Combine sirloin strips with ginger garlic pepper and salt in a large bowl allowing them to marinate for 15 minutes. This brief marination is crucial as it tenderizes the meat while infusing it with aromatic flavors without making it mushy. The salt helps break down muscle fibers ensuring juicy results.
- Create the Sauce Base:
- Whisk together coconut milk sugar Sriracha lime zest and juice with remaining salt until perfectly blended. This creates a harmonious mixture where no single flavor dominates. The coconut milk provides creaminess the sugar balances the heat the lime adds brightness and the Sriracha delivers that signature warmth.
- Sear the Beef:
- Heat oil in a large skillet over medium high heat until it shimmers. Add the marinated beef in a single layer working in batches if necessary to avoid overcrowding. Stir fry quickly for just 2 3 minutes until the beef loses its pink color but remains tender. Remove immediately to prevent overcooking as it will return to the pan later.
- Cook the Vegetables:
- In the same skillet with residual beef flavors add remaining oil and stir fry red pepper red onion jalapeno and final garlic clove. The key is maintaining high heat for quick cooking about 2 3 minutes until vegetables are bright and crisp tender. They should retain some texture for contrast in the final dish.
- Combine and Finish:
- Pour in the prepared coconut milk mixture bringing it to a gentle simmer. Return the beef to the pan and add fresh spinach allowing it to wilt into the sauce. The residual heat wilts the spinach perfectly while warming the beef without overcooking it. Finish with a generous sprinkle of green onions and fresh cilantro.

My favorite moment with this dish happened last summer when my nephew who claims to hate vegetables cleaned his plate and asked for seconds. The secret was letting him help prepare it which somehow made those vibrant vegetables suddenly acceptable.
Make Ahead Options
This stir fry works beautifully as part of a meal prep strategy. You can marinate the beef up to 24 hours ahead of time which not only saves preparation time but actually improves the flavor. The sauce components can also be mixed and refrigerated separately. When ready to cook simply bring everything to room temperature for about 20 minutes before proceeding with the recipe.
Perfect Pairings
While this stir fry is substantial enough to enjoy on its own it pairs wonderfully with jasmine rice which soaks up the flavorful sauce. For a lower carb option cauliflower rice works surprisingly well. If you want to stretch the meal further serve alongside simple steamed dumplings or a light cucumber salad dressed with rice vinegar to provide a refreshing contrast to the spicy elements.
Adjusting The Heat Level
The beauty of this recipe lies in its adaptability. For those who enjoy more intense heat add the jalapeno seeds or substitute with a hotter pepper like Thai bird chili. Conversely for a milder version reduce the Sriracha by half and remove the jalapeno entirely. The coconut milk provides enough creaminess to balance even significant adjustments to the heat level making this dish accessible to all palates.

This dish transforms weeknight meals into a vibrant and delightful experience. Once you try it, it will become a regular recipe in your kitchen!
