Instant Pot Flank Steak Recipe: Asian-Inspired Soy-Ginger Glaze

This Instant Pot method transforms tough flank steak into tender, flavorful perfection in under an hour. The secret lies in the pressure cooking process, which breaks down fibers quickly while locking in juices.

An Asian-inspired soy-ginger glaze adds depth with its balance of salty, sweet, and spicy notes. The sauce reduces naturally as the steak cooks, creating a rich, glossy finish that coats every slice.

What emerges is fall-apart tender meat with bold, aromatic flavors—ideal for serving over rice or alongside steamed vegetables. The hands-off cooking method ensures consistent results every time.

This technique proves that restaurant-quality steak doesn’t require a grill or hours of marinating. The 30-minute cook time makes it perfect for weeknight dinners.

Ingredients for Instant Pot Flank Steak

Flank steak and bold Asian flavors transform into a restaurant-quality meal with minimal effort.

The flank steak is the foundation here. Opt for USDA Choice or Prime for best results—look for good marbling at Whole Foods or your local butcher. Trimming excess fat prevents a greasy sauce. For the soy sauce, Kikkoman or San-J offer consistent quality. Fresh ginger is non-negotiable; pre-ground lacks the bright, zesty punch this dish deserves (worth the extra minute to grate).

No fresh ginger? Ground ginger at half the amount in a pinch, but fresh is ideal. Swap brown sugar for honey or maple syrup if needed. Low-sodium soy sauce can be replaced with coconut aminos for a gluten-free option. The rice vinegar can be apple cider vinegar, but its milder flavor won’t cut through the richness as effectively.

Store raw flank steak in the coldest part of your fridge for up to 3 days. The glaze keeps for 1 week in an airtight container. Leftovers reheat beautifully—slice thinly against the grain for serving the next day.

Step-by-Step Instructions for Asian-Inspired Soy-Ginger Flank Steak

This method ensures tender, flavorful beef with a glossy glaze using your pressure cooker.

Step 1: Sear the Flank Steak for Depth of Flavor

Set your Instant Pot to the Sauté function and add the 1 tbsp Vegetable Oil. Once the oil shimmers, pat the 2 lb Flank Steak completely dry with paper towels and season generously with salt and pepper. Sear the steak for 3-4 minutes per side until deeply browned.

This initial sear creates a flavorful fond in the pot, which will dissolve into the cooking liquid and enrich the sauce. Don’t rush this step—proper browning develops complex, meaty flavors. Remove the steak to a plate and set aside.

Step 2: Build the Aromatic Soy-Ginger Glaze

In the same pot, add the 4 cloves Garlic Cloves and 2 tbsp Fresh Ginger, cooking for 30 seconds until fragrant. Pour in the 0.5 cup Soy Sauce, 0.25 cup Brown Sugar, 3 tbsp Rice Vinegar, 1 tbsp Sesame Oil, and 0.5 tsp Red Pepper Flakes. Stir to dissolve the brown sugar.

Deglaze the pot by scraping up any browned bits with a wooden spoon. This ensures no flavor is left behind. The mixture should be bubbling and smell intensely aromatic—this is the foundation of your glaze.

Step 3: Pressure Cook to Tender Perfection

Return the seared flank steak to the pot and add the 0.5 cup Beef Broth. Secure the lid, set the valve to Sealing, and cook on High Pressure for 20 minutes. Allow a natural release for 10 minutes before quick-releasing any remaining pressure.

The steak will emerge incredibly tender, easily pierced with a fork. This pressure cooking method transforms typically tough flank steak into a melt-in-your-mouth texture while infusing it with the bold soy-ginger flavors.

Step 4: Thicken the Glaze and Finish

Transfer the steak to a cutting board and set aside. Mix the 1 tbsp Cornstarch with 1 tbsp of cold water, then stir this slurry into the cooking liquid in the pot. Set the Instant Pot back to Sauté and simmer for 2-3 minutes until the glaze thickens to a syrupy consistency.

Slice the steak thinly against the grain for maximum tenderness. Arrange the slices on a platter, drizzle with the thickened glaze, and garnish with the 4 whole Scallions (thinly sliced) and 1 tbsp Sesame Seeds. Serve immediately while the glaze is still glossy and hot.

Dietary Considerations for This Dish

Gluten-Free Adaptation

Swap the soy sauce for tamari or coconut aminos to make this dish gluten-free. Both alternatives provide the same salty depth without wheat. I use San-J tamari for its rich, balanced flavor. 💪

Low-Sodium Option

Reduce sodium by using low-sodium soy sauce and low-sodium beef broth. This simple change cuts the salt content significantly while keeping all the flavor. The 30-minute cook time allows the reduced-sodium ingredients to meld beautifully.

Keto-Friendly Version

Replace the brown sugar with monk fruit sweetener or erythritol in equal amounts. These sugar substitutes caramelize similarly, maintaining the glaze’s glossy texture. I find Lakanto Golden works best for this recipe.

Dairy-Free Notes

This recipe is naturally dairy-free, so no modifications are needed. The soy-ginger glaze and beef base contain no dairy products. Always check your beef broth label, as some brands may contain trace amounts.

High-Protein Serving

Serve this over cauliflower rice instead of regular rice to boost the protein-to-carb ratio. A 4-ounce serving of flank steak provides about 30 grams of protein, making it a powerhouse meal. 💛

Allergen Awareness

This dish contains soy (from soy sauce) and sesame (from sesame oil). For soy allergies, use coconut aminos. For sesame allergies, substitute with avocado oil. Always verify labels for cross-contamination warnings.
