Figuring out how long to cook turkey london broil in oven is the key to a perfect meal. A turkey London broil’s ideal doneness in the oven depends on a specific roasting duration and internal temperature.
This guide gives you clear, step-by-step instructions. You will learn the exact timing, temperature, and techniques needed.
We’ll cover everything from selecting the right cut to checking for doneness. Let’s get started.
how long to cook turkey london broil in oven
The total cooking time for a turkey London broil in the oven typically ranges from 25 to 40 minutes. This depends heavily on the size and thickness of your cut and your desired level of doneness.
For a standard 1.5 to 2-pound turkey London broil, roasting at 375°F (190°C) usually takes 30 to 35 minutes. The only reliable way to know it’s done is by using a meat thermometer.
You should aim for an internal temperature of 165°F (74°C) at the thickest part. Always let the meat rest for 10 minutes after cooking for juicier results.
What is a Turkey London Broil?
First, it’s important to clarify what this cut actually is. “London broil” traditionally refers to a method of cooking beef, not a specific cut. For turkey, it’s similar.
A turkey London broil is typically a boneless, butterflied turkey breast that has been flattened to an even thickness. Sometimes it’s a large, thick cut from the thigh.
This preparation allows for quicker, more even cooking. It’s often sold pre-packaged and may be seasoned or marinated.
Key characteristics include:
- Boneless and skinless
- Butterflied and pounded flat
- Usually weighs between 1.5 and 3 pounds
- Even thickness for consistent roasting
Essential Tools for the Job
Having the right tools makes the process foolproof. You don’t need fancy equipment, but a few basics are non-negotiable.
Your success hinges on accurate temperature control. Guesswork leads to dry or undercooked meat.
Must-Have Equipment
- Instant-Read Meat Thermometer: This is the most critical tool. A digital thermometer gives you an exact internal temperature reading in seconds.
- Rimmed Baking Sheet or Roasting Pan: A sheet pan with sides is perfect. You can line it with foil or parchment for easier cleanup.
- Wire Rack (Optional but Helpful): Placing the meat on a rack set inside the pan allows hot air to circulate all around, promoting even browning.
- Sharp Knife and Cutting Board: For trimming any excess fat or silverskin before cooking and for slicing afterwards.
- Aluminum Foil: Essential for tenting the meat while it rests after cooking.
Preparing Your Turkey London Broil
Proper preparation sets the stage for a flavorful and juicy result. This step should not be rushed.
Always start by patting the turkey dry with paper towels. Removing surface moisture helps the seasoning stick and promotes better browning.
If your turkey London broil is tied with string or netting, it’s generally best to leave it on during cooking to maintain its shape. You can remove it before slicing.
Seasoning and Marinating Options
Seasoning is where you can add your personal touch. A simple approach often works best for this lean cut.
A basic dry rub of salt, black pepper, garlic powder, and paprika is excellent. Drizzle a little olive oil over the meat first to help the spices adhere.
For more flavor, consider a wet marinade. An acidic component like lemon juice or vinegar can help tenderize the meat slightly.
Simple Marinade Idea:
- 1/4 cup olive oil
- 2 tablespoons soy sauce
- Juice of one lemon
- 2 cloves minced garlic
- 1 teaspoon dried herbs (like thyme or rosemary)
Marinate the turkey in a sealed bag in the refrigerator for at least 2 hours, or up to 12 hours for deeper flavor. Always pat it dry again before cooking.
Step-by-Step Oven Cooking Instructions
Follow these steps for a perfectly cooked turkey London broil every single time. The process is straightforward.
Step 1: Preheat and Prepare the Pan
Preheat your oven to 375°F (190°C). This is a good middle-ground temperature that cooks the meat through without excessive browning.
While the oven heats, prepare your baking sheet. Line it with foil for easy cleanup and place a wire rack on top if you’re using one. Lightly coat the rack or pan with cooking spray.
Step 2: Season and Place in Oven
Place your prepared turkey London broil on the rack or directly on the pan. If you didn’t marinate, brush it lightly with oil and apply your seasonings generously on all sides.
For added flavor, you can place a few sprigs of fresh herbs or slices of onion and lemon in the pan underneath the rack.
Step 3: The Roasting Process
Place the pan in the preheated oven on the center rack. The cooking time will vary, but here is a reliable guideline based on weight.
- 1 to 1.5 lbs: 20 to 30 minutes
- 1.5 to 2 lbs: 30 to 35 minutes
- 2 to 2.5 lbs: 35 to 40 minutes
- 2.5 to 3 lbs: 40 to 45 minutes
Remember, these are estimates. Oven temperatures can vary, and the starting temperature of the meat (room temp vs. cold from fridge) affects timing.
Step 4: Checking for Doneness
Begin checking the internal temperature about 5-10 minutes before the expected finish time. Insert your meat thermometer into the thickest part of the cut, avoiding any pockets of fat or the pan below.
The turkey is safe to eat when it reaches 165°F (74°C). For the most juicy texture, some cooks prefer to remove it from the oven at 160°F (71°C). The temperature will continue to rise by 5-10 degrees during the resting period, a phenomenon called carryover cooking.
Step 5: The Crucial Resting Period
As soon as the turkey reaches your target temperature, transfer it to a clean cutting board. Loosely tent it with a piece of aluminum foil.
Let it rest for a full 10 minutes. This allows the juices, which have been forced to the center by the heat, to redistribute throughout the meat. Skipping this step will result in juices running out onto the cutting board when you slice, leaving the meat drier.
Internal Temperature Guide and Doneness
Color is not a reliable indicator of doneness in turkey. The only way to guarantee safety and perfect results is with a thermometer.
- 165°F (74°C): The USDA-recommended safe temperature for all poultry. At this temperature, the meat will be fully cooked, opaque, and safe to eat.
- 160°F (71°C): The temperature at which you can remove the turkey from the oven if you plan for carryover cooking. The residual heat will bring it to 165°F as it rests.
If you’re using a pre-marinated or pre-seasoned product, always check the label for any specific cooking instructions provided by the manufacturer.
Common Mistakes to Avoid
Avoiding these common errors will improve your results significantly. Even experienced cooks can make some of these slips.
- Not Using a Thermometer: Guessing based on time or appearance is the number one cause of overcooked or undercooked meat.
- Overcrowding the Pan: If you are cooking multiple pieces, ensure there is space between them for air to circulate. Otherwise, they will steam instead of roast.
- Skipping the Rest: Cutting into the meat immediately after cooking lets all the flavorful juices escape. Be patient.
- Using the Wrong Oven Rack: Place the pan in the center of the oven. A rack too high can cause excessive browning; too low can lead to uneven cooking.
- Not Preheating the Oven: Putting the meat into a cold oven drastically changes the cooking time and can make the texture tough.
Slicing and Serving Suggestions
After the turkey has rested, it’s time to slice. Use a sharp carving knife or chef’s knife for clean cuts.
Always slice against the grain. Look for the direction of the muscle fibers and cut perpendicular to them. This shortens the fibers, making each bite much more tender.
Slice the meat into thin strips, about 1/4 to 1/2 inch thick. This is the classic presentation for a London broil style dish.
Serve your turkey London broil with your favorite sides. It’s a versatile protein that pairs well with many dishes.
Great Serving Ideas:
- Traditional: Mashed potatoes, gravy, and green beans
- Healthy: A large salad with a vinaigrette and roasted sweet potatoes
- Comfort Food: Macaroni and cheese with steamed broccoli
- Simple: On a sandwich with lettuce, tomato, and a bit of mayonnaise
Storing and Reheating Leftovers
Proper storage keeps your leftovers safe and tasty. Cool the sliced turkey to room temperature within two hours of cooking.
Store it in an airtight container in the refrigerator. It will keep for 3 to 4 days. For longer storage, you can freeze it for up to 3 months.
To reheat, the goal is to add moisture back. Avoid the microwave if possible, as it can make the meat rubbery.
Better Reheating Methods:
- Oven Method: Place slices in a baking dish with a few tablespoons of broth or water. Cover with foil and heat at 325°F until warm.
- Skillet Method: Heat a skillet over medium-low heat with a teaspoon of oil or broth. Add the slices and cover, heating gently for a few minutes, turning once.
Alternative Cooking Methods
While the oven is a great method, you have other options. Each technique offers a slightly different result.
Grilling Turkey London Broil
Grilling adds a wonderful smoky flavor. Preheat your grill to medium-high heat (about 400°F).
Oil the grates well. Grill the turkey for 6-8 minutes per side, or until the internal temperature reaches 165°F. Let it rest as you would with oven cooking.
Using an Air Fryer
The air fryer is excellent for a quick cook. Preheat the air fryer to 370°F.
Cook the turkey London broil for 18-25 minutes, flipping halfway through. Always check the temperature with a thermometer, as air fryer models vary widely.
Frequently Asked Questions (FAQ)
What temperature should the oven be for turkey London broil?
The ideal oven temperature is 375°F (190°C). This provides a balance between thorough cooking and surface browning. You can adjust slightly to 350°F for slower cooking or 400°F for a quicker, more browned finish, but you must adjust the timing accordingly.
Can I cook a frozen turkey London broil in the oven?
It is not recommended to cook it from frozen in the oven. The exterior will overcook before the interior reaches a safe temperature. The safest method is to thaw it completely in the refrigerator first, which can take 24-48 hours depending on size. Then, cook it using the standard method.
How do I know when my turkey London broil is done without a thermometer?
While a thermometer is strongly advised, you can check by making a small cut into the thickest part. The meat should be opaque all the way through with no traces of pink, and the juices should run clear, not pink. This method is less reliable than using a thermometer.
Why is my turkey London broil tough?
Toughness is usually caused by overcooking. Turkey breast is very lean and has little fat to keep it moist. Cooking it past 165°F can cause the proteins to tighten and squeeze out moisture, resulting in a dry, tough texture. Not slicing against the grain can also make it seem tough to chew.
What’s the difference between turkey London broil and regular turkey breast?
A turkey London broil is typically a butterflied and flattened cut, creating a larger, thinner piece of meat that cooks quickly and evenly. A regular turkey breast roast is often a whole or half breast with a more irregular, thicker shape that requires longer, slower cooking. The London broil is designed for the specific method of quick roasting and thin slicing.
