This Sheet Pan Corned Beef is an easy one-pan meal that’s perfect for busy days! It includes tender corned beef, colorful veggies, and flavorful spices all roasted together.
I love how simple this recipe is—just toss everything on the sheet pan and let the oven do the work! Perfect for a fuss-free dinner with tasty leftovers!
Key Ingredients & Substitutions
Corned Beef Brisket: This is the star of the dish! A 3 to 4-pound brisket is ideal for enough flavor and tenderness. If you can’t find corned beef, consider using a brisket or other cuts like beef round, but they won’t have that signature flavor.
Potatoes: Baby yellow and red potatoes bring great texture. If they’re not available, you can swap with regular potatoes, or even sweet potatoes for a twist. Just adjust the cook time slightly, as sweet potatoes may need less time.
Carrots: They add sweetness and color. Feel free to use other root vegetables like parsnips or turnips for variety. I’ve even added sliced bell peppers, which work wonderfully too!
Mustard: Whole grain mustard gives a nice tang. If you’re out, a mix of Dijon and yellow mustard can be a solid alternative. I love a bit of Dijon for extra kick!
Thyme: Dried or fresh works well here. I personally prefer fresh for the lovely aroma it adds, but if dried is what you have, that’s perfect too. Always adjust the amount, as dried herbs tend to be stronger.
How Do You Ensure Your Vegetables Roast Perfectly?
Roasting vegetables to perfection can be tricky. The key is in preparation and even coating. First, be sure to cut your veggies into uniform sizes so they cook evenly. Toss them in olive oil, garlic, and seasonings well to ensure they are all nicely coated.
- Layer the veggies out on the sheet pan, leaving space between them for airflow.
- Halfway through cooking, toss them gently and baste the corned beef with juices. This helps all ingredients brown nicely.
- If you want extra crispiness, consider broiling them for a minute or two at the end, watching closely!
How to Make Sheet Pan Corned Beef
Ingredients You’ll Need:
For the Corned Beef and Vegetables:
- 3 to 4 pounds corned beef brisket (with spice packet)
- 1 pound baby yellow potatoes, halved if large
- 1 pound baby red potatoes, halved if large
- 3 large carrots, peeled and cut into chunks
- 2 medium onions, peeled and quartered
- 3 cloves garlic, minced
For Seasoning:
- 1 tablespoon whole grain mustard
- 2 teaspoons dried thyme or 1 tablespoon fresh thyme leaves
- 1 teaspoon black pepper
- 1/2 teaspoon mustard seeds (optional, for extra crunch)
- 2 tablespoons olive oil
- Salt to taste (be cautious as corned beef is already salty)
For Garnish:
- Fresh chives or parsley, chopped
How Much Time Will You Need?
This delicious meal takes about 15 minutes to prep and around 90 minutes to 2 hours to roast in the oven. Total, you’re looking at about 2 to 2 hours and 15 minutes from start to finish, including resting time. It’s perfect for a hearty dinner!
Step-by-Step Instructions:
1. Preheat Oven:
First things first, let’s get that oven warmed up! Preheat it to 375°F (190°C) so it’s nice and hot when it’s time to roast.
2. Prepare Vegetables:
Grab a large mixing bowl and toss in your halved baby potatoes, chunks of carrots, and quartered onions. Add in the minced garlic, olive oil, thyme, salt (if using), and black pepper. Mix everything together until all the veggies are well coated in that delicious mixture.
3. Assemble on Sheet Pan:
Now it’s time to get everything on the pan! Spread the vegetable mixture evenly across a large rimmed baking sheet. Make sure there’s enough space for air to circulate. Then, place your corned beef brisket right in the center, fat side up. This helps keep it juicy!
4. Season Corned Beef:
Take the whole grain mustard and rub it all over the corned beef. Next, sprinkle the spice mix from the packet evenly over the meat. If you’re feeling fancy, toss some mustard seeds on top for that extra crunch!
5. Roast:
Slide the sheet pan into your preheated oven and let it roast for about 90 minutes to 2 hours. You want the corned beef to be tender and the veggies to be golden. Don’t forget to baste the beef with pan juices halfway through and gently toss the veggies for even cooking!
6. Rest and Slice:
Once it’s done roasting, carefully remove the pan from the oven. Let the corned beef rest for about 10 minutes—this helps keep it juicy! Then, slice it against the grain into thick, tasty pieces.
7. Serve:
Finally, garnish your dish with fresh chives or parsley for a pop of color and extra flavor. Serve those delicious slices of corned beef alongside the roasted potatoes, carrots, and onions. Enjoy your hearty and flavorful sheet pan corned beef meal!
Can I Use Different Vegetables for This Recipe?
Absolutely! While the recipe calls for baby potatoes, carrots, and onions, you can substitute with other root vegetables like parsnips, sweet potatoes, or even Brussels sprouts. Just remember to cut them into similar sizes for even cooking.
How Do I Adjust the Cooking Time for a Smaller or Larger Brisket?
For a smaller brisket (around 2-3 pounds), reduce the cooking time to about 1.5 to 1.75 hours. For a larger brisket (over 4 pounds), you may need to extend roasting time to about 2 to 2.5 hours. Always check for tenderness as the best indication of doneness!
What Should I Do With Leftover Corned Beef?
Leftover corned beef can be stored in an airtight container in the fridge for up to 3 days. You can enjoy it cold in sandwiches, or heat it in a skillet or microwave for a warm meal. It’s also great chopped into hash or added to soups!
Can I Prepare This Recipe Ahead of Time?
Yes, you can prep the vegetables and season the corned beef the night before! Just keep everything covered and refrigerated. When you’re ready to cook, bring it to room temperature for about 30 minutes, then roast as directed.
