Thinking about cooking a show-stopping brisket but feeling a little intimidated? You’re not alone! A perfectly cooked brisket is a thing of beauty – incredibly tender, juicy, and packed with flavor. While smoking often comes to mind, your oven is actually a fantastic, reliable tool for achieving fantastic results right in your kitchen.
The big question on many home cooks’ minds, especially for a substantial cut, is: how long to cook a 10 lb brisket in the oven? The short answer is typically around 6-8 hours, but there’s a little more to it than just a timer. Let’s break down everything you need to know to transform that 10-pound marvel into a culinary masterpiece.

Understanding Brisket: The Star of Your Meal
Brisket is a tough cut of meat from the cow’s lower chest or breast. It’s rich in connective tissue, which is why it needs a long, slow cooking process to break down, melt, and become melt-in-your-mouth tender. This “low and slow” approach is crucial for achieving that incredible texture and infusing it with flavor.
The Golden Rule: Low and Slow in the Oven
For a 10 lb brisket, patience is your best friend. We’re aiming for a slow roast at a lower temperature, which allows the collagen to convert into gelatin, resulting in that desirable tender texture. While precise times can vary slightly based on your oven and the brisket’s exact thickness, here’s a general guideline:
- Temperature: Most recipes recommend a consistent oven temperature between 250°F (120°C) and 300°F (150°C).
- Time: Plan for approximately 45-60 minutes per pound at 250°F (120°C). So, for a 10 lb brisket, you’re looking at about 7 to 10 hours of cooking time. If you opt for 275°F (135°C), it might be closer to 6-8 hours. At 300°F (150°C), you’re still looking at a good 5-7 hours.
Remember, these are estimates. The true indicator of doneness is always the internal temperature, not just the clock!
Your Step-by-Step Guide to Oven-Cooked Brisket Perfection
1. Brisket Prep: Trim and Season
- Trimming: A full packer brisket has two parts – the “flat” (leaner) and the “point” (fattier). It will also have a substantial fat cap. Trim the hard, excess fat down to about a ¼ to ½ inch thickness. This fat will render and keep the meat moist. Remove any silver skin or tough membranes.
- Seasoning: This is where the flavor magic happens! A simple yet effective rub often includes salt, black pepper, garlic powder, onion powder, and paprika. Apply generously all over the brisket, pressing it into the meat. For best results, do this 12-24 hours in advance and let it chill in the fridge, allowing the flavors to penetrate.
2. The Cooking Process: Searing and Roasting
- Searing (Optional but Recommended): For a richer color and deeper flavor, consider searing the brisket on all sides in a hot, oven-safe pan on the stovetop before it goes into the oven. This creates a delicious crust.
- Into the Pan: Place the brisket fat-side up (or down, opinions vary, but fat up often helps self-baste) in a sturdy roasting pan. You can add a little liquid (beef broth, apple cider vinegar, or even beer) to the bottom of the pan – about half an inch – to help keep moisture in the oven environment.
- Cover and Cook: Tightly cover the roasting pan with heavy-duty aluminum foil. This traps moisture, essentially creating a mini-steamer in your oven, ensuring a tender result.
- Oven Time: Place your covered brisket in the preheated oven (250-275°F / 120-135°C). Start checking for tenderness and internal temperature after about 6 hours.
3. The Crucial Internal Temperature
For tender brisket, you’re aiming for an internal temperature between 195°F (90°C) and 205°F (96°C) when measured in the thickest part of the flat. Use a reliable meat thermometer. The brisket should feel “probe tender” – the thermometer should slide in and out with very little resistance, like it’s going into warm butter.
4. The Rest: Don’t Skip It!
This step is non-negotiable for a juicy brisket. Once your brisket reaches the target temperature, remove it from the oven, but keep it tightly wrapped (or wrap in foil and then a towel). Let it rest for at least 1-2 hours, or even longer (up to 4 hours) in an insulated cooler. Resting allows the muscle fibers to relax and reabsorb the juices, ensuring a supremely moist and flavorful slice.
5. Carving: Slice Against the Grain
Once rested, unwrap your brisket. It will likely have two distinct sections (flat and point) with grains running in different directions. Identify the grain and slice a little more thickly than deli meat, always against the grain. This shortens the muscle fibers, making each bite incredibly tender.
Troubleshooting & Pro Tips
- The “Stall”: Don’t panic if your brisket’s temperature seems to plateau for a few hours. This is normal! It’s called “the stall,” and it’s due to evaporative cooling. Just keep cooking.
- Don’t Peek Too Much: Every time you open the oven, you lose heat, extending cooking time. Resist the urge!
- Monitor with a Probe Thermometer: An oven-safe leave-in probe thermometer is an excellent investment for brisket, letting you track progress without opening the oven.
- Moisture is Key: If your brisket seems to be drying out, you can add a bit more broth to the pan or spritz it with apple cider vinegar, water, or broth during longer cooks.
- Plan Ahead: Brisket cooking takes time. Start early, or even cook it the day before, reheat, and slice just before serving.
Frequently Asked Questions About Oven Brisket
Do I really need to cook it for so long?
Yes! The long, slow cook is what breaks down the tough connective tissue, turning it into tender, succulent meat. Rushing the process will result in a tough, chewy brisket.
Should I cover the brisket while cooking in the oven?
Absolutely. Covering it tightly with foil traps steam and moisture, creating a humid environment that helps the brisket stay juicy and tender as it cooks.
What if my brisket finishes early?
No problem! Keep it tightly wrapped in foil and then wrap it in a towel. Place it in an empty cooler (without ice) – it can happily rest there for several hours and stay warm until you’re ready to carve and serve.
Can I cook a smaller brisket for less time?
Yes, smaller briskets will cook faster. The general rule of 45-60 minutes per pound still applies, but always rely on the internal temperature for doneness.

Cooking a 10 lb brisket in the oven might seem like a daunting task, but with a little patience and these tips, you’ll be serving up incredibly flavorful and tender meat that will have everyone asking for your secret. So go ahead, grab that beautiful cut, and let your oven do the work!
