How Long To Cook Roast Beef At 150 C? Here’s The Answer!
What To Know
- Cooking roast beef at a low temperature allows the connective tissue to break down slowly, resulting in a melt-in-your-mouth texture.
- While cooking time estimates are helpful, using a meat thermometer is the most accurate way to determine when the roast is cooked to your desired doneness.
- Vacuum-seal the roast and cook it in a water bath at a precise temperature.
When it comes to cooking the perfect roast beef, timing is everything. Cooking at a lower temperature, such as 150°C, ensures an evenly cooked and tender joint. But how long should you cook it for? Here’s a comprehensive guide to help you achieve roast beef perfection.
Understanding the Cooking Process
Cooking roast beef at a low temperature allows the connective tissue to break down slowly, resulting in a melt-in-your-mouth texture. The longer you cook it, the more tender it will become.
Determining Cooking Time Based on Weight
The weight of the roast is the primary factor that determines the cooking time. As a general rule, allow:
- 20-25 minutes per 500g for rare
- 25-30 minutes per 500g for medium-rare
- 30-35 minutes per 500g for medium
- 35-40 minutes per 500g for medium-well
- 40-45 minutes per 500g for well-done
Using a Meat Thermometer for Accuracy
While cooking time estimates are helpful, using a meat thermometer is the most accurate way to determine when the roast is cooked to your desired doneness. Insert the thermometer into the thickest part of the roast, avoiding any bones.
- Rare: 49-52°C
- Medium-rare: 52-55°C
- Medium: 55-60°C
- Medium-well: 60-65°C
- Well-done: 65°C and above
Resting the Roast
Once the roast has reached the desired internal temperature, it’s essential to let it rest for 15-20 minutes before carving. This allows the juices to redistribute, resulting in a more tender and flavorful roast.
Tips for a Perfectly Cooked Roast
- Season the roast generously with salt and pepper before cooking.
- Use a roasting rack to allow air to circulate around the roast.
- Baste the roast with its own juices every 30 minutes or so.
- Cover the roast loosely with foil if it starts to brown too quickly.
- Let the roast come to room temperature before cooking for more even cooking.
Roasting Different Cuts of Beef
The cooking time and temperature may vary slightly depending on the cut of beef you’re using. Here are some guidelines:
- Rib Roast: 20-25 minutes per 500g for medium-rare
- Tenderloin: 15-20 minutes per 500g for medium-rare
- Sirloin Roast: 25-30 minutes per 500g for medium-rare
- Bottom Round Roast: 30-35 minutes per 500g for medium-rare
The Perfect Accompaniments
Roast beef is a versatile dish that pairs well with various sides. Consider serving it with creamy mashed potatoes, roasted vegetables, or a rich gravy.
Beyond the Oven: Alternative Cooking Methods
While roasting in the oven is the most common method, you can also cook roast beef using other techniques:
- Sous Vide: Vacuum-seal the roast and cook it in a water bath at a precise temperature.
- Slow Cooker: Cook the roast on low for 6-8 hours for fall-off-the-bone tenderness.
- Smoker: Smoke the roast for several hours for a smoky and flavorful dish.
Key Points: A Culinary Symphony
Cooking roast beef at 150°C is an art form that requires patience and precision. By following these guidelines and experimenting with different techniques, you can create a roast beef masterpiece that will impress your family and friends.
