I’ve done so many air fryer recipes, I’m getting worried my other kitchen gadgets are feeling left out! This London broil pressure cooker recipe is my attempt to fix that. I love Instant Pot recipes too!
Pressure cooking is different than air fryer cooking in that it’s harder to adjust cooking times with the Instant Pot. With air frying, you continually check on the food to stir, flip, or rotate. With pressure cooking, you set the time and temperature and leave things alone until the food is done.
For this reason, pressure cooking London broil (and other cuts of meat) carries a bit of a risk. You're not going to know you’ve overcooked it until you release the pressure on the Instant Pot. Luckily, it’s pretty easy to avoid shoe leather beef if you follow this recipe.
We’re going to pressure cook the beef for the shortest possible time in the Instant Pot- 5 minutes. Then we’re going to quick release the pressure. This is the best way to ensure we don’t overcook London broil in the Instant Pot.
You can always go back and cook an undercooked cut of beef for an additional 10-15 minutes. However, once you overcook something, you can’t undo it. Follow this recipe and don’t risk it!

🐄 How to Make Instant Pot London Broil
Here are the step-by-step instructions to make the best Instant Pot London broil. (Get a printable recipe card with quantitites of ingredients at the end of the post.)
- Classic London broil is first marinated and then broiled (hence the name). It’s best to begin marinating your London broil the night before. To make the marinade, stir together the beef broth, balsamic vinegar, tomato paste, dried thyme, soy sauce, black pepper, and garlic. Put the beef in a gallon-size Ziplock bag.
- Pour the marinade into the bag with the beef. Seal the bag, pressing out as much air as you can.
- Keep the bag with the beef and marinade in the refrigerator overnight, flipping it every once in a while. You want the marinade to be able to penetrate the beef from all sides. Be sure to marinate the beef for a minimum of 4-6 hours.
- The next day, remove the beef from the marinade and pat it dry. Set your Instant Pot to “high saute” and add butter and olive oil. Once the butter melts, add thinly sliced onions and let them soften. (If you’d like mushroom gravy, you can add some sliced mushrooms too.)
- Push the onions to one side of the pot and add the beef. Allow the beef to brown for a couple of minutes on all sides. You just want a quick sear; you’re not cooking it through yet.
- Next, turn the pot off and pour the marinade from the bag into the pot. The liquid level should reach the minimum required for pressure cooking by the Instant Pot. Put the lid on the pot and close the vent.
⏲️ London Broil Instant Pot Cook Time
Pressure cook London Broil on high pressure for 5 minutes with the bean/chili setting. Keep in mind this is a 2 lb London broil Instant Pot recipe (meat is about 1-inch/2.54 cm thick).
This is the lowest cooking time my multi-cooker allows. The meat setting does not allow a 5-minute cooking time, which is why we’re using the setting for beans.
You may have to play with the settings on your Instant Pot to find the one that permits the lowest pressure cooking time. This cook time will get your London broil cooked to medium or medium-rare, with a pink center.
At the end of the cook time, quick release the pressure and use tongs to lift the London broil out of the liquid. Check the temperature of the thickest part of the beef. It should have reached a safe minimum internal temperature of 145 degrees Fahrenheit (63C). Let the beef rest for 10 minutes while you make the gravy.
To make the gravy, set the Instant Pot to “high sauté.” Let the marinade and onion mixture bubble for 5 minutes, and then whisk in the xanthan gum. Let the gravy thicken over the heat for about 5 minutes, whisking occasionally.
Feel free to use cornstarch or whole grain flour as a thickener instead, if you would prefer. You will need to use more cornstarch or flour to thicken, compared to the small amount of xanthan gum.
🔪 How to Cut London Broil
London broil should be cut against the grain into thin slices. To serve, slice the beef and ladle some gravy on top. This seared steak has a juicy inside with great flavor. YUM!
🥩 What cut of meat is used for London broil?
London broil is most commonly made with top-round steak or flank steak. Sometimes top round steaks are labeled “London broil” in grocery stores, even though London broil refers to a cooking method, not a cut of meat. Top sirloin can also work in this London broil recipe, though it tends to be pricier than top round.
🥗 What to Serve with London Broil
Wondering how to serve London broil? I like to serve London broil over a fluffy bed of mashed potatoes with carrots, cauliflower, or roasted Brussels sprouts on the side.
Here are a few more side dishes that go with London broil:
- Air Fryer Spaghetti Squash
- Air Fryer Frozen French Fries
- Keto Air Fryer Radishes (a low carb alternative to potatoes!)
London broil leftovers can be kept in an airtight container in the refrigerator for up to 3-4 days, or freeze them. Use leftovers to make tacos, casseroles, or sandwiches.
FAQs
How do you cook London broil so it’s not tough?
To avoid tough London broil, don't overcook it, and ensure it is marinated long enough and marinated properly. London broil is typically made with lean, thick cuts of beef that are tough. However, a good recipe for London broil (like this one!) will ensure the steak is tender by the time it reaches your plate.
What cooking method is preferred for London broil?
London broil is typically marinated then seared under a broiler in the oven. This is the best way to cook London broil for the most reliably consistent results.
How to make a London broil Instant Pot recipe with no marinade?
You must use a liquid to safely pressure cook foods in an Instant Pot, so don’t skip the marinade. Additionally, marinating London broil is a critical step to help tenderize it.
How to make London broil in the Instant Pot from frozen?
To make London broil in the Instant Pot from frozen, season and marinate the piece of meat before freezing. Then place the frozen London broil in the Instant Pot with sufficient liquid, and pressure cook on high for 30 minutes. Natural pressure release for 10 minutes, then quick release the remaining pressure.
Check to ensure the London broil reached a minimum safe temp of at least 145F (63C) and add cooking time if needed. After pressure cooking, slice and serve. Note: I DO NOT recommend making London broil from frozen, as it turns out very well done more similar to a pot roast.
That said, I know some of y’all are going to try this regardless, so thought I’d offer some starter directions. 🙂

💭 Expert Tips from a Dietitian
This is a level 2 recipe (transition or weight maintenance). London broil has a lot to offer in terms of nutrition. If you struggle with iron deficiency, beef provides the highly bioavailable heme iron you may benefit from. Beef is also rich in vitamin B12, zinc, selenium, niacin, and vitamin B6. Oh, and don’t forget about beef’s high-quality protein!
A (realistically sized) serving of the London broil by itself is under 500 calories. However, with a pile of mashed potatoes and roasted Brussels sprouts, my meal was over 900 calories! Remember that regardless of the dietary lifestyle you’ve chosen, you need to maintain a calorie deficit to lose weight.
The key to a lighter meal here is that you want to add in non-starchy veggies without lots of oil. Non-starchy veggies give a big boost to the volume of meals for very few calories. They’re also low carb and keto friendly.
