The Essential Ingredients for This Vibrant Stir-Fry
This recipe uses a handful of fresh, high-impact ingredients to create its signature spicy, sweet, and savory flavor.
- The Beef (The Cut and the Slice are Key!):
- Top Sirloin Steak: The recipe calls for top sirloin, which is a fantastic, relatively lean but still tender and flavorful cut of beef that is perfect for stir-frying. Flank steak is another excellent choice. The most important secret to tender stir-fry beef is to slice it very thinly, against the grain.
- The Creamy & Spicy Coconut Sauce: This is the heart of the dish’s flavor.
- Coconut Milk: For the richest, creamiest sauce, it is highly recommended to use a full-fat, canned coconut milk. “Light” coconut milk will work, but it will result in a thinner sauce.
- The Flavors: The sauce is a perfect balance of four key tastes: Spicy (from the Sriracha and fresh jalapeño), Sweet (from the sugar), Sour (from the fresh lime juice and zest), and Salty (from the soy sauce and salt).
- Sriracha: This classic, vibrant red chili sauce adds a wonderful, garlicky heat. You can add as little or as much as you like to customize the spice level.
- The Aromatics: For the absolute best, most vibrant and authentic flavor, it is essential to use freshly minced ginger root and freshly minced garlic.
- The Vegetables: A simple but colorful and crunchy blend of sweet red bell pepper, red onion, and fresh baby spinach provides the perfect texture and freshness.
Pro Tutorial: The Secret to Paper-Thin Sliced Beef
This is the most important step for tender, authentic stir-fried beef, and it’s surprisingly easy!
- Freeze the Beef: Take your piece of sirloin steak, wrap it tightly in plastic wrap, and place it in the freezer for about 30 to 45 minutes.
- Check for Firmness: You want the beef to be very firm to the touch, but not frozen solid like a rock.
- Slice Against the Grain: Place the firm beef on your cutting board. Look closely at the meat to see which direction the muscle fibers are running. Using a very sharp chef’s knife, slice the beef perpendicular (against the grain) into paper-thin pieces.
Step-by-Step to the Perfect Spicy Beef Stir-Fry
This delicious meal comes together in minutes. The key is to have all your ingredients prepped and ready to go next to your stove before you begin!
Step 1: Marinate the Beef and Prepare the Sauce
Step 1: In a large bowl, toss your thinly sliced beef with the 1 tablespoon of minced fresh ginger, 2 of the minced garlic cloves, the 1/2 teaspoon of salt, and the 1/4 teaspoon of pepper. Let the beef stand and marinate for at least 15 minutes.
Step 2: While the beef is marinating, prepare your sauce. In a small bowl, whisk together the 1 cup of light coconut milk, the 2 tablespoons of sugar, the 1 tablespoon of Sriracha chili sauce, the 1/2 teaspoon of grated lime zest, the 2 tablespoons of lime juice, and the remaining 1/4 teaspoon of salt until the sugar has completely dissolved.
Part 2: The High-Heat Stir-Fry
Step 1: In a large skillet or a wok, heat 1 tablespoon of the canola oil over medium-high heat.
Step 2: Add the marinated beef to the hot skillet. Stir-fry for 2 to 3 minutes, until the beef is no longer pink and is lightly browned. Remove the cooked beef from the pan and set it aside.
Step 3: Stir-fry the 1 sliced large sweet red pepper, the 1/2 sliced medium red onion, the 1 thinly sliced jalapeño pepper, and the remaining clove of minced garlic in the remaining 1 tablespoon of oil for 2 to 3 minutes, just until the vegetables are crisp-tender.
Part 3: Finish the Sauce and Combine
Step 1: Stir your prepared coconut milk sauce mixture into the skillet with the vegetables and heat it through.
Step 2: Add the 4 cups of fresh baby spinach and the cooked beef back to the pan. Cook, stirring occasionally, until the spinach has wilted and the beef is heated all the way through.
Sprinkle the finished dish with the sliced green onions and the chopped fresh cilantro, and serve immediately.

Frequently Asked Questions (FAQs)
Q1: What is the absolute, number one secret to tender, not chewy, stir-fry beef?
The secret is to slice your beef very thinly, against the grain. The absolute easiest way to do this at home is to partially freeze the beef for about 30-45 minutes before you slice it. The firmness of the partially frozen meat will allow you to use a very sharp knife to get those beautiful, paper-thin, uniform slices that will cook up to be incredibly tender.
Q2: What kind of coconut milk is best for a sauce like this one?
For the richest, creamiest sauce, it is highly recommended to use a full-fat, canned coconut milk. “Light” coconut milk, as the recipe suggests, will also work, but your final sauce will be a bit thinner. Do not use the refrigerated coconut milk that is sold in a carton as a beverage, as it will not create a rich and creamy sauce.
Q3: Can I make this stir-fry ahead of time?
This dish comes together so incredibly quickly that it is at its absolute best when it is made fresh. However, for a fantastic time-saving trick, you can prepare all your components ahead of time. You can slice and marinate the beef, chop your vegetables, and whisk together your sauce. Then, the final stir-fry will take less than 10 minutes.
Q4: What is the best pan to use for a stir-fry?
The key to a good stir-fry is high heat. A traditional, carbon steel wok is fantastic because it heats up quickly and evenly. If you don’t have one, a large, 12-inch cast-iron or heavy-bottomed stainless steel skillet is the next best choice.
Q5: Can I make this recipe gluten-free?
Yes, it’s very easy to make this recipe gluten-free! Simply substitute the soy sauce with a high-quality, gluten-free tamari or coconut aminos. All the other ingredients in the recipe are naturally gluten-free.
