The time needed to cook London Broil in the oven at 350°F depends on the size and thickness of your steak. Typically, a 1-inch thick steak will need between 15 to 20 minutes of cooking. However, if you want your steak to be medium-rare or rare, you’ll need to reduce the cooking time by a few minutes.

How Long to Cook London Broil in Oven at 350

Estimating Cooking Time for London Broil

The cooking time for London broil varies depending on a few factors, including the size of the meat cut and your preferred level of doneness. However, as a general rule of thumb, you should plan on cooking your London broil for around 15-20 minutes per pound at 350 degrees Fahrenheit.

Factors that Affect Cooking Time

As mentioned above, there are a few factors that can impact how long it takes to cook your London broil in the oven at 350 degrees.

One of these factors is the thickness of the meat cut – thicker cuts will require more cooking time than thinner ones. Additionally, if you prefer your meat more well-done than rare, this will also increase cooking time.

Another factor that can affect cooking time is how long you marinate your London broil before cooking it. Marinating can help tenderize tough cuts of beef and add flavor, but it can also add moisture to the meat which can impact how quickly it cooks.

Setting the Oven Temperature

When it comes to setting your oven temperature for cooking London broil, many recipes call for temperatures between 375-450 degrees Fahrenheit. However, if you’re looking specifically to cook your London broil at 350 degrees Fahrenheit, this temperature range should work just fine as well.

It’s important to note that if you plan on using a different temperature than what is called for in a recipe or recommended by a professional chef, you may need to adjust your cooking time accordingly.

Lower temperatures generally mean longer cooking times, while higher temperatures can result in a shorter cooking time.

Size of the London Broil Cut

As mentioned earlier, the size of your London broil cut will also impact how long it takes to cook.

Thicker cuts will require more cooking time than thinner ones, and if you have a particularly large cut of meat, you may need to increase your overall cook time by several minutes.

Additionally, the size of your baking dish can also impact how quickly your London broil cooks. A smaller baking dish will result in a faster cook time since there is less space for heat to circulate around the meat.

The Sear-Roast Method of Cooking London Broil

One popular method for cooking London broil is known as the sear-roast method. To use this method, start by heating up a large oven-safe skillet on medium-high heat on the stove.

Add some oil or butter to the skillet and let it get hot before adding in your seasoned beef.

Sear each side of the meat for 2-3 minutes until they are browned before transferring the skillet with beef to preheated oven and continue roasting until it reaches desired doneness– around 15-20 minutes per pound at 350°F.

This searing process helps create a flavorful crust on the outside of your London broil while also keeping it tender and juicy on the inside.

Checking for Doneness Without an Instant Read Thermometer

If you don’t have an instant-read thermometer handy, there are other ways to check if your London broil is cooked through without cutting into it and ruining its juiciness.

One way is using kitchen timer’s manual calculations based on general cooking times like mentioned earlier or by testing its softness with finger pressure technique or knife poking method.

Additionally, you can check for doneness by cutting a small slit into the thickest part of the meat and inspecting its color. If the center is pink or red, it’s still rare. A light pink color will mean it’s medium-rare, while a brownish-pink color will indicate that your meat is cooked to medium consistency.

Safe Internal Temperature for Cooked London Broil

Finally, it’s essential to note that all cooked beef should meet a minimum safe internal temperature of 145 degrees Fahrenheit before being served. To ensure your London broil has reached this temperature, use an instant-read thermometer and check its thickest part.


In conclusion, cooking London broil in the oven at 350 degrees Fahrenheit requires around 15-20 minutes per pound of beef cut, with factors such as marination method, cooking preference and baking dish size may affect overall cooking time.

The sear-roast method is one popular way to cook London broil in the oven that produces juicy and flavorful results. And always remember to check for safe internal temperature before serving your meal!
