Who doesn’t like a delicious beef roast, especially when it’s the best London Broil in the Instant Pot? This is a set it and forget it recipe, which is what we all bought pressure cookers for. This London Broil recipe uses simple ingredients and can be paired with classic sides such as rice, potatoes, salads, and roasted vegetables. Make this London Broil for your last-minute holiday guests as an elegant meal. No one will know it was made quickly in the pressure cooker with no overnight marinade required!
The Ingredients
These ingredients come together to make a classic roast dinner recipe. A London broil is a cut of beef that is a tough steak, such as skirt steak, bottom, or inside round sirloin. For mine, I used sirloin. For the veggies, use whatever root vegetables you think would cook best in the stout bbq sauce gravy that pressure cooked the beef.
- London Broil
- stout beer
- BBQ sauce
- white onion
- salt & pepper
- carrots
- green peas
- parsley
- celeriac (celery root) or turnip, optional
Pressure Cook the London Broil
This easy instant pot London Broil Recipe comes together by putting the stout beer at the bottom of your Instant Pot. Lay a trivet on top. Brush the trivet with a little olive oil and use the rest of the oil to rub the steak. Season with salt and pepper. Lay the steak onto the trivet and top with BBQ sauce. It’s ok if some go off the sides. Pressure cook on high for 35 min.
Broil the Steak
After you release the pressure, have a broiler ready. Line a tray with aluminum foil and carefully transfer the steak to the tray. Here I liked to add a little bit of extra BBQ sauce to create a glaze. Broil for 2-3 min. This makes your meat nice and caramelized and brings out all that delicious natural sweetness.
Cook the Veggies
No London Broil dinner is complete without vegetables. While the steak broils, add your carrots, celeriac (celery root), and peas to the instant pot cooking liquid. Simmer until they are nice and cooked and tender. This also reduces the sauce for your steak. Serve the vegetables and some of the sauce on top of the steak and garnish with parsley. You can optionally remove the vegetables, cover them to keep them warm and continue to reduce the sauce. I would highly recommend this. The porter / BBQ sauce becomes delicious when butter is incorporated into it.
