What Ingredients You Will Need

This Easy Instant Pot Mongolian Beef with Broccoli uses simple, wholesome ingredients that come together effortlessly to deliver bold flavor and a satisfying texture. Most are pantry staples, with a few fresh touches that make all the difference.

• Beef: 1 lb (450 g) flank steak, thinly sliced against the grain (for tenderness).
• Broccoli: 3 cups florets, fresh and crisp (frozen works in a pinch but fresh is best).
• Soy Sauce: 1/3 cup (80 ml), low sodium recommended (I prefer Kikkoman for balanced flavor).
• Brown Sugar: 1/4 cup (50 g), packed (adds that signature caramel sweetness).
• Garlic: 3 cloves, minced (fresh, not jarred if you can help it).
• Ginger: 1 tablespoon, freshly grated (for that warm, zesty kick).
• Beef Broth: 1/2 cup (120 ml), low sodium (helps create the luscious sauce).
• Cornstarch: 2 tablespoons, mixed with 2 tablespoons water to form a slurry (for thickening).
• Vegetable Oil: 2 tablespoons, for sautéing (can swap with avocado or canola oil).
• Green Onions: 2 stalks, sliced thin (for garnish and fresh bite).
• Red Pepper Flakes: Optional, 1/4 teaspoon if you like a little heat.

For those wanting to customize, you can swap brown sugar for coconut sugar for a deeper flavor or use tamari to make it gluten-free. This recipe’s flexible — just keep the balance of sweet and salty in mind. Fresh broccoli is key here to add that crispness that pairs beautifully with the tender beef.

Equipment Needed

• Instant Pot or Electric Pressure Cooker: The star of the show here — essential for the quick cooking magic.
• Sharp Knife and Cutting Board: For slicing the beef thinly and prepping broccoli.
• Measuring Cups and Spoons: To keep the sauce perfectly balanced.
• Mixing Bowl: For tossing the beef with cornstarch before cooking.
• Wooden Spoon or Silicone Spatula: For stirring without scratching your pot.

If you don’t have an Instant Pot, a slow cooker or stovetop method can work but will need more time and some extra attention. I’ve tried both, and the Instant Pot version wins for speed without sacrificing flavor or texture. For budget-friendly options, there are many reliable Instant Pot brands available — just make sure they have a sauté and pressure cook function.

Preparation Method

1. Prep the Beef: Thinly slice 1 lb (450 g) flank steak against the grain into bite-sized strips. Toss the beef with 2 tablespoons cornstarch mixed with 2 tablespoons water to coat evenly. This helps lock in juices and thickens the sauce later. Set aside.
2. Sauté Aromatics: Turn your Instant Pot to sauté mode and heat 2 tablespoons vegetable oil. Add 3 cloves minced garlic and 1 tablespoon freshly grated ginger. Stir for about 30 seconds until fragrant but not browned — you want that fresh aroma to fill the air.
3. Cook the Beef: Add the beef strips in a single layer (you might need to do this in batches). Sear quickly for 2-3 minutes until just browned on the edges but not cooked through. This step seals in flavor and texture.
4. Add Sauce Ingredients: Pour in 1/3 cup (80 ml) low sodium soy sauce, 1/4 cup (50 g) packed brown sugar, and 1/2 cup (120 ml) beef broth. Stir to combine, scraping any browned bits off the bottom — this is flavor gold.
5. Pressure Cook: Seal the Instant Pot lid and set to high pressure for 8 minutes. It takes about 10 minutes to come to pressure, then the timer counts down. This tenderizes the beef and melds flavors perfectly.
6. Quick Release & Add Broccoli: Once cooking is done, carefully quick release the pressure. Open the lid and add 3 cups fresh broccoli florets. Stir them into the sauce, then switch back to sauté mode to cook uncovered for 3-4 minutes until broccoli is bright green and tender-crisp.
7. Thicken the Sauce: Give the sauce a good stir, then add a slurry made from 1 tablespoon cornstarch mixed with 1 tablespoon water. Stir constantly for 2 minutes until the sauce thickens to a glossy finish.
8. Final Touches: Turn off the Instant Pot, sprinkle sliced green onions and optional red pepper flakes for heat. Give it a final stir and it’s ready to serve!

Pro tip: If your sauce looks too thin, just sauté for a bit longer with the lid off, stirring frequently. And don’t skip slicing the beef thin — it cooks faster and stays tender.

Cooking Tips & Techniques

Cooking Mongolian beef in the Instant Pot is a game changer, but here are some tips I learned the hard way:

• Slice Against the Grain: This simple trick makes the beef tender instead of tough. It’s worth the extra minute or two.
• Don’t Overcrowd the Pot: Searing the beef in batches helps get that nice caramelized edge instead of steaming.
• Use Fresh Garlic and Ginger: Jarred versions just don’t pack the same punch here.
• Quick Release Pressure: Avoids overcooking the broccoli and keeps it vibrant and crisp.
• Thicken Last: Adding cornstarch slurry at the end lets you control the sauce consistency perfectly.
• Multitask with Sauté Mode: Use sauté for browning and final sauce thickening without dirtying extra pans.

Once, I rushed and added broccoli before pressure cooking — it turned into a soggy mess. Lesson learned! This recipe balances speed with texture, so timing is everything.

Variations & Adaptations

Want to mix things up? This Easy Instant Pot Mongolian Beef with Broccoli recipe is flexible and adapts well to your preferences:

• Vegetarian Version: Swap beef for firm tofu or tempeh. Press and cube tofu, then follow the same steps but reduce pressure cooking time to 5 minutes.
• Spicy Kick: Add 1 teaspoon of chili garlic sauce or extra red pepper flakes for a fiery twist that wakes up your taste buds.
• Low-Carb Adaptation: Replace brown sugar with a keto-friendly sweetener like erythritol and soy sauce with coconut aminos to keep it paleo-friendly.
• Seasonal Swap: In summer, try swapping broccoli for fresh snap peas or green beans to add a bright, crisp bite.

I once made this with mushrooms instead of broccoli for a cozy fall dinner, and it was just as comforting. Feel free to customize and find your perfect spin!

Serving & Storage Suggestions

Serve your Easy Instant Pot Mongolian Beef with Broccoli hot over steamed jasmine or brown rice to soak up all that delicious sauce. A side of simple fried rice or steamed dumplings pairs beautifully, too. For drinks, a chilled jasmine tea or light lager complements the sweet-savory flavors nicely.

Store leftovers in an airtight container in the fridge for up to 3 days. Reheat gently in a skillet over medium heat or microwave in short bursts, stirring to keep the broccoli from getting mushy. You can freeze portions for up to 2 months, but note the broccoli texture may soften after thawing. Flavors often develop even more after a day in the fridge, making it a great make-ahead meal.
