Pin this This beef and broccoli dish features tender strips of flank steak paired with crisp-tender broccoli florets, all coated in a rich savory sauce with hints of sweetness from brown sugar and aromatic notes from garlic, ginger, and sesame oil. The Instant Pot makes quick work of normally tough cuts of meat, delivering perfectly tender beef in just 10 minutes of pressure cooking.
The sauce combines soy sauce and beef broth for depth, brown sugar for subtle sweetness, and rice vinegar for brightness. A cornstarch slurry thickens everything beautifully during the final sauté. Serve over steamed rice or noodles for a complete meal that comes together in under 40 minutes, making it perfect for busy weeknights when you want something hearty and flavorful without spending hours at the stove.
The first time I made beef and broccoli in my Instant Pot, I stood in front of the counter watching that steam release like magic. My husband walked in and asked what smelled so incredible, and I honestly felt a little proud saying I'd barely done anything. Now it's the dinner I turn to when I want takeout flavors without the wait or the delivery fee.
Last winter my sister came over complaining about her latest takeout disaster, so I made her this instead. She took one bite, put her fork down dramatically, and demanded I teach her the recipe right then at my kitchen island.
Ingredients
- Flank steak or sirloin: Slice this thinly against the grain or you'll end up chewing forever, trust me on this one
- Cornstarch coating: This little trick is what makes the beef feel velveted like at Chinese restaurants
- Low sodium soy sauce: Regular soy sauce will make it way too salty once the sauce reduces
- Brown sugar: Balances the saltiness and gives you that gorgeous caramelized finish
- Fresh garlic and ginger: Jarred ginger works in a pinch but fresh makes such a difference
- Broccoli florets: Cut them into bite sized pieces so they cook evenly in that short second press
- Cornstarch slurry: This transforms the thin cooking liquid into that thick glossy sauce you want
- Sesame seeds and green onions: Totally optional but they make it look like you tried really hard
Instructions
- Prep the beef:
- Toss those thin slices with cornstarch until they look lightly dusted, not clumpy
- Make the sauce:
- Whisk everything together until the brown sugar completely dissolves into the liquid
- Pressure cook the beef:
- Pour the sauce over the beef in the pot and give it a stir, then lock that lid tight for 10 minutes
- Add the broccoli:
- Quick release the steam, throw in the broccoli, and do just 1 more minute on high pressure
- Thicken the sauce:
- Whisk your cornstarch into cold water first, then stir it in while hitting sauté mode for 2 to 3 minutes

Getting The Beef Right
Cutting against the grain is the step everyone rushes but it matters so much. Look for those lines running through the meat and slice perpendicular to them, almost like you're cutting through a deck of cards.
Customize Your Veggies
Sometimes I throw in sliced bell peppers or snap peas if that's what's in my crisper drawer. Just keep in mind that softer vegetables like zucchini might get mushy if you add them too early.
Serve It Up
This needs something underneath to soak up all that sauce. White rice works perfectly but cauliflower rice is great if you're watching carbs.
- Cook your rice before you start so everything is ready at the same time
- Double the sauce ingredients if you love extra sauce for your rice
- Leftovers actually reheat beautifully for lunch the next day
Pin this Serve this hot and watch how fast the plates get cleaned. It's become one of those recipes I can make without even thinking about the steps anymore.
Recipe FAQs
- → What cut of beef works best?
-
Flank steak or sirloin are ideal choices because they become tender during pressure cooking. Slice the beef thinly against the grain before cooking for the most tender results. Other lean cuts like skirt steak also work well.
- → Can I use frozen broccoli?
-
Yes, frozen broccoli works perfectly fine in this dish. Add it during the second pressure cooking step just like fresh broccoli. You may need to adjust the cooking time slightly depending on your preference for tenderness.
- → How do I make this gluten-free?
-
Substitute tamari or coconut aminos for the soy sauce, and ensure your beef broth is certified gluten-free. Double-check all ingredient labels, especially condiments like rice vinegar and any pre-mixed seasonings.
- → Can I marinate the beef ahead of time?
-
Absolutely. Marinating the beef in the sauce mixture for up to 30 minutes before cooking adds extra flavor. Simply coat the beef with cornstarch first, then combine with the sauce and let it rest in the refrigerator until ready to cook.
- → What other vegetables can I add?
-
Sliced carrots, bell peppers, snap peas, or mushrooms all complement the flavors beautifully. Add hearty vegetables like carrots with the beef during the first pressure cook, and quick-cooking vegetables like snap peas with the broccoli in the second round.
- → Why does the sauce need a cornstarch slurry?
-
The slurry is essential for thickening the sauce after pressure cooking. The high moisture environment of the Instant Pot can make sauces thin, so whisking cornstarch with cold water creates a smooth thickener that transforms the cooking liquid into a glossy, rich coating for the beef and broccoli.
