Instructions
For the Marinade and to Cook Beef
Whisk all the ingredients together until evenly incorporated.
Place your cut of beef in a gallon-size zip top bag and pour in the marinade.
Press out as much of the air as you can and seal the bag. Massage the meat through the bag so the marinade and garlic can get down in the diamond pattern.
Place the bag in a baking dish (just in case of leaks) and marinate overnight.
Remove the meat from the fridge about an hour before cooking. Take the meat out of the bag and pat it dry.
Reserve the marinade in a small pan. (See Alternative Slow Cooker Instructions in the Notes).
Set a rack in the center of the oven and preheat to 375F.
Heat grill pan over medium-high heat.
Sear meat for 4 minutes a side (rotating 90 degrees after 2 minutes to achieve a diamond pattern).
Place the pan in the preheated oven and roast to an internal temperature of 125F. Cooking time will vary depending on the thickness of the roast. My 2" thick roast took about 25 minutes. Make sure you have a meat thermometer to check the temperature.
Remove the meat to a cutting board and tent with foil for 15-20 minutes.
While the Beef is resting, make the sauce.
For the Sauce
Bring the reserved marinade to a boil over medium-high heat. Boil for 3 minutes to slightly reduce and get as much flavor out of the garlic as you can. Strain through a fine-mesh strainer and put back on the heat.
Add the heavy cream and flour/water slurry.
Bring to a boil and cook for about a minute to cook off the raw flour taste.
Use an immersion blender to emulsify the sauce. Keep warm over low heat until serving.
For the Optional Onions and Mushrooms
Slice the onion thinly.
Wash and quarter the crimini mushrooms (cut larger caps into 6ths)
Heat a heavy skillet (I used cast iron) over medium-low heat. Add half the oil.
Add all the onions and a pinch of salt and cook slowly over medium-low heat for about 10 minutes, until the onions have given up a bit of their juices and are softening.
Add the pepper relish and cook for an additional 20 minutes until onions are very soft and lightly caramelized. Stir frequently so they don't burn and adjust heat as necessary.
Add the rest of the oil, the mushrooms and thyme along with another heavy pinch of kosher salt and black pepper.
Cook until the mushrooms release their juices, the juices evaporate and the onions and mushrooms are nicely caramelized, another 10-15 minutes. Taste and adjust seasonings as necessary.
To Serve the London Broil
After resting, slice the meat thinly across the grain. Pass the sauce and the caramelized onions and mushrooms at the table.
Notes
Prep time does not include time to marinate or resting time. Cooking time is approximate.Slow Cooker Directions Marinate the beef overnight. Add the beef and all the marinade to your slow cooker and cook on low heat for 8-10 hours or until very tender. Serve the meat in the sauce as-is or keep the meat warm and finish the sauce as in the original instructions. You can also add the onions and mushrooms to the slow cooker at the same time if you'd like.
