Ingredients

For the Beef:

• 1 lb (450g) flank steak or sirloin, thinly sliced against the grain
• 2 tbsp cornstarch
• 1 tbsp vegetable oil
• 1 tsp salt
• 1/2 tsp black pepper

For the Sauce:

• 3 tbsp light soy sauce
• 2 tbsp sweet chili sauce
• 1 tbsp rice vinegar
• 1 tbsp honey or brown sugar
• 2 cloves garlic, minced
• 1 inch (2.5cm) fresh ginger, grated
• 2-3 red chilies, thinly sliced (adjust to taste)

For Garnish:

• 3 green onions, sliced diagonally
• 1 tsp sesame seeds
• 1 red bell pepper, thinly sliced
• 1/2 tsp red chili flakes (optional for extra heat)

The key to perfect Air Fryer Crispy Chilli Beef lies in using thinly sliced beef (freezing it for 15 minutes makes slicing easier) and cornstarch for that signature crispiness. Fresh chilies provide better flavor than dried, but you can adjust the quantity based on your heat preference.

Pro Tips

1. Perfect Beef Slicing Technique
For the ultimate Air Fryer Crispy Chilli Beef, the meat needs to be cut correctly. Place your steak in the freezer for 15-20 minutes until slightly firm but not frozen solid. This makes it much easier to slice thinly against the grain. The thinner your slices (about 1/4 inch or less), the crispier your beef will become. Remember that thin, uniform slices will cook evenly and achieve that perfect texture.

2. The Double Coating Method
To achieve restaurant-level crispiness, toss your beef with cornstarch, then let it sit for 5-10 minutes before tossing again. This double-coating creates microscopic layers that crisp up beautifully in the air fryer. Ensure each piece is well-coated but shake off any excess to prevent clumping. This technique is the difference between good and outstanding Air Fryer Crispy Chilli Beef.

3. Temperature and Timing Mastery
Don’t overcrowd your air fryer basket – this is crucial. Work in batches if necessary, placing beef strips in a single layer with space between each piece. Preheat your air fryer to 390°F (200°C) for optimal crispness. Spraying the beef lightly with oil before cooking creates that authentic fried texture. Check and shake the basket halfway through cooking to ensure even browning across all pieces.

Instructions

Step 1: Prepare the Beef
Start by slicing your beef as thinly as possible against the grain. Place the sliced beef in a medium bowl and add the cornstarch, salt, and pepper. Toss thoroughly until each piece is evenly coated. Let the beef sit for 10 minutes to allow the cornstarch to adhere properly. This resting period is key to achieving that perfect crispy texture in your Air Fryer Crispy Chilli Beef.

Step 2: Preheat and Cook
Preheat your air fryer to 390°F (200°C) for 3-5 minutes. While it’s heating, lightly spray the beef with vegetable oil. Arrange the beef strips in a single layer in your air fryer basket, being careful not to overcrowd (work in batches if needed). Cook for 6-8 minutes, shaking the basket halfway through, until the beef turns golden brown and develops that signature crispiness. You’ll notice the edges becoming deliciously caramelized.

Step 3: Prepare the Sauce
While the beef is cooking, whisk together all the sauce ingredients in a small bowl: soy sauce, sweet chili sauce, rice vinegar, honey, minced garlic, grated ginger, and sliced chilies. The aroma of these combined ingredients will give you a preview of the amazing flavors to come. If you prefer a thicker sauce, mix in 1/2 teaspoon of cornstarch.

Step 4: Combine and Finish
Once all your beef is crispy, transfer it to a large skillet or wok over medium-high heat. Pour the sauce over the beef and toss quickly to coat each piece evenly. The key is to work fast so the beef stays crispy – cook for just 1-2 minutes until the sauce slightly reduces and becomes glossy. Add your sliced bell peppers during the last 30 seconds for a slight crunch.

Step 5: Serve and Garnish
Transfer your Air Fryer Crispy Chilli Beef to a serving plate and sprinkle generously with sliced green onions and sesame seeds. The contrast between the dark, glossy beef and the bright green onions makes for a stunning presentation. Serve immediately while still hot and crispy, alongside steamed rice or noodles to soak up that delicious sauce.

Variations

Vegetarian Crispy Chilli “Beef”
Transform this dish into a plant-based delight by substituting the beef with either extra-firm tofu or seitan. Slice the tofu into thin strips, press well to remove excess moisture, then proceed with the same cornstarch coating method. Alternatively, use mushrooms like king oyster or shiitake sliced into strips for a meaty texture. The air fryer works brilliantly with these vegetarian alternatives, creating a similar crispiness to the traditional Air Fryer Crispy Chilli Beef.

Orange Crispy Chilli Beef
For a citrusy twist on classic Air Fryer Crispy Chilli Beef, add 2 tablespoons of orange juice and 1 teaspoon of orange zest to the sauce. This creates a flavor profile similar to orange chicken but with the signature beef crispiness. The citrus notes brighten the dish and balance the heat from the chilies beautifully. Garnish with additional orange zest for an aromatic finish.

Low-Carb Crispy Chilli Beef Bowl
Create a keto-friendly version by serving your Air Fryer Crispy Chilli Beef over cauliflower rice instead of traditional rice. Replace the sugar or honey in the sauce with a keto-friendly sweetener, and use a minimal amount of cornstarch or substitute with almond flour for the coating. Add extra vegetables like zucchini, broccoli, or cabbage to increase the fiber content while keeping carbs low.

Storage and Serving

Storage Solutions
While Air Fryer Crispy Chilli Beef is best enjoyed immediately for maximum crispiness, you can store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, avoid the microwave which will make the beef soggy. Instead, place it back in the air fryer at 350°F (175°C) for 3-4 minutes until heated through and some crispness has been restored. For longer storage, you can freeze the cooked beef separately from the sauce for up to 1 month.

Serving Suggestions
Serve your Air Fryer Crispy Chilli Beef over a bed of jasmine rice or egg-fried rice for a classic takeout-style meal. For a lower-carb option, pair with steamed vegetables or a simple cucumber salad to balance the rich flavors. For an impressive dinner party presentation, serve the beef in lettuce cups with extra sliced chilies and green onions on the side for guests to customize their heat level. Complete the meal with a side of vegetable spring rolls or hot and sour soup for an authentic Chinese restaurant experience at home.

FAQs

Can I use other cuts of beef for this recipe?
Yes, while flank and sirloin are ideal for Air Fryer Crispy Chilli Beef, you can also use ribeye, skirt steak, or even rump steak. The key is slicing thinly against the grain and ensuring you don’t overcook leaner cuts.

How can I make this dish less spicy?
To reduce the heat, remove the seeds from the fresh chilies before slicing, or reduce the quantity. You can also substitute with bell peppers for the visual appeal without the heat. The sweet chili sauce can be replaced with a milder sweet sauce like plum or hoisin.

My beef didn’t get crispy enough. What went wrong?
Three common issues: 1) The beef slices were too thick; 2) The air fryer was overcrowded, preventing proper air circulation; or 3) The cornstarch coating wasn’t even. Make sure to slice thinly, cook in batches, and thoroughly coat each piece of beef.

Can I make this recipe in advance for a party?
For best results, prepare the beef and sauce separately in advance. Air fry the beef just before serving and toss with the heated sauce at the last minute to maintain the signature crispiness of Air Fryer Crispy Chilli Beef.

Is there a gluten-free version?
Absolutely! Simply substitute regular soy sauce with tamari or coconut aminos, and double-check that your sweet chili sauce is gluten-free (most are, but some contain wheat-based ingredients).

This Air Fryer Crispy Chilli Beef is comfort food at its finest — transforming a beloved takeout dish into a healthier, homemade version without sacrificing any of that addictive crispiness or flavor.
