Gluten Free Baked Mustard Corned Beef with Vegetables

There is something equal parts festive and comforting about corned beef. Whether it’s piled skyscraper high on a sandwich or baked slowly with a pile of vegetables to sop up all of their juices, it’s meant to celebrate a holiday, and a celebration unto itself.


Is there any more perfect bite than vegetables basking in the drippings of meat? Gluten Free Baked Mustard Corned Beef with Vegetables is not only easy to prepare, but also only requires easily accessible ingredients.

  • Corned Beef – You will want about a three-pound corned beef for this recipe. This brined and cured piece of meat comes already packing bold and savory flavor so it doesn’t take a lot to allow it to shine.
  • Cabbage – Corned beef’s best friend and a classic pairing.
  • Sweet Potato – Adds natural sweetness that compliments all of the savory flavors.
  • Carrots – Just like the sweet potato adds natural sweetness.
  • Parsnips – Carrots sassier cousin. A little spicier than carrots.
  • Whole Grain Mustard – Gives the corned beef a beautiful crust and bold, savory flavor.
  • Kosher Salt/Black Pepper
  • Bloody Mary Seasoning – Spiceology’s Bloody Mary Seasoning adds another savory element. You can use the code SALTY for 10% off of your order.
  • Olive Oil


Sláinte is a common way to toast in Irland and everything about this dish makes me want to say cheers. Gluten Free Baked Mustard Corned Beef with Vegetables is truly the gift that keeps on giving.

There’s just something magic about meat that roasts slow and low atop a pile of vegetables. The way its juices baste the vegetables, sinking in, permeating every bite makes them almost as crave worthy as the corned beef itself.

This is not the corned beef and cabbage you may have grown up with. Ditch that packet of pickling spices that comes along with your beef and leave the crockpot hidden away. We’re going to create our own flavor profile and allow this to bake slowly in the Dutch oven.

What goes better with corned beef than mustard? This corned beef gets a generous coating of whole grain mustard. As it cooks the tangy bright flavor seeps into the meat adding a savory note.

The rainbow of vegetables, cabbage, sweet potatoes, carrots, parsnips, and regular potatoes get seasoned with salt, pepper, and Spiceology’s Bloody Mary blend. This tangy spice combines the flavors of tomatoes, garlic, and vinegar for the perfect accent to both the meat and vegetables.

Slicing into Gluten Free Baked Mustard Corned Beef with Vegetables

With just a little prep work at the beginning, this delicious one pot meal couldn’t be easier. Get out your Dutch oven and let’s break down it down.

  • Pregame! Your corned beef comes brined. You will want to remove some of that saltiness, so thoroughly rinse it off and dry it.
  • Preheat your oven to 350 degrees.
  • Cut your vegetables into large chunks. As the corned beef roasts, they’ll break down.
  • Add your vegetables to your Dutch oven and toss with olive oil, salt, pepper, and the bloody mary seasoning.
  • Place the corned beef on top of the vegetables. Coat the entire top with the mustard.
  • Place the lid on your Dutch oven and bake for 2 1/2 hours.
  • Uncover the corned beef and allow it to cook for another half hour until the top is bronzed and it is tender.


Feel free to replace any of the vegetables in this recipe with your favorites. Brussel sprouts can be used in place of the cabbage. Potatoes can be added instead of sweet potatoes. Use what you have and what you like.


There is nothing better than leftover corned beef. It’s perfect for everything from that piled high sandwich, to sliders, and of course hash. Keep it stored in an airtight container in the refrigerator and it will keep for up to five days.

Top Tips for Gluten Free Baked Mustard Corned Beef with Vegetables

Always let your meat rest before slicing into it. This will allow the juices to redistribute into the corned beef. In addition, make sure to cut your vegetables into fairly similar sizes. This will allow them to cook evenly.
