Corned Beef in Oven Recipe

So I had shared almost all the ways to cook this packaged beef, except in the oven. I guess I am just a small countertop appliance girl that those were my go tos. Yes you can make it a lot quicker and just as tender if you follow our Ninja Foodi corned beef and cabbage recipe. You may not have that though.

Everyone has an oven so it was time to cover all my basis. Then year to year you can decide which way to go, or what is your favorite amongst them all. Basically the same ingredients are needed for all of them.

Ingredients

• 2.5-3 lb corned beef brisket is a good size, ours was 2.66 lbs
• Beer broth or water
• 2 potatoes quartered, optional
• Mustard sauce with items below mixed together
  • Brown sugar
  • Yellow mustard
  • Dijon mustard
  • Honey

from frozen

If you have had a forgetful moment and your meat is not defrosted I have a tip!! You can cook frozen corned beef low and slow this way. Only difference is that you will save the sauce to spoon over when done.

Is flat cut or point cut corned beef better?

So let’s talk about the two choices you will encounter at the store. You’ll find point and flat cut, the latter is WAY better. It is just a bit more expensive but tenderer with a bit more fat so it stays moist. Trust me, just start with the best of the best with this. You do not need to add anything else but I would suggest either potatoes or an onion.

Should you rinse corned beef before you cook it?

DON’T DO IT y’all. You love this hunk of meat because of the brine it has been soaked in. That great salty flavor is because of that. There is still some remaining on the outside when you take it out of that package. It will have a stronger (what you normally would expect at a restaurant) flavor if you don’t rinse it first.

Should you cook cabbage with your corned beef brisket?

Y’all, don’t skip the veggies I’m telling you. I suggest serving with baked cabbage steaks, that are so buttery and delish. You can put it in near the end on another shelf until tender. I wouldn’t cook anything with your meat other than potatoes since those take a long time too.

Of course Corned beef Mustard Sauce on top is optional but let me tell you that it is SO popular with everyone. Poured over the top in the last 15 minutes allows it to brown just a bit on top and kinda’ bake on. TONS of flavor this adds, a bit sweet and savory at the same time.

I used a 9×13 dish and everything fit nicely. You do need something with high sides so the liquid stays contained. You need enough beer or broth so that your meat is at least half way submerged. A roasting pan with water or beer would work well too.

How to Bake Corned Beef Brisket in Oven with Mustard

• Preheat oven and lay brisket with the fat side facing the on the top.
• Quarter potatoes (if adding them) and place around meat.
• Sprinkle spice packet over the top.
• Pour beer or liquid of your choice over the top. Cover your pan with aluminum foil tightly so it can essentially steam and break down the connective tissues.
• Bake meat and vegetables for about 1 hour per pound + about 10 min.
• Remove foil, and in a small bowl whisk up mustard sauce. Pour over the top.
  • make sure is covers the whole top and is dripping on to the sides.
• Bake uncovered just to brown the top a bit.
• Put foil on top to keep warm, allow to rest before slicing.
• Serve with tender potatoes seasoned with salt and pepper, and slow cooker cabbage and enjoy.

For another low and slow, make our Dutch Oven corned beef in the oven if you have that pot.

What temperature should you cook corned beef in the oven?

350 Fahrenheit is ideal. Low and slow is the best. The only exception to this rule is if you were to cook Instant Pot corned beef. That of course is much higher in temp and pressure, quicker, but turns out just as good. You can’t bake the sauce on to the top in that machine though.

You just throw the beef and vegetables right in there with liquid so it steams to tender under that foil and that is it really. If you wanted to use a larger pan you could add large chunks of peeled carrots in there as well. Or make our pressure cooker fried cabbage which turns out amazing.

Now let’s talk about a variety of simple cabbage recipes you could make and serve with it. Now you could put a few leaves of it under your foil in the last 20 minutes or so to wilt, sure. We really found that we liked it better when cooked separate and then served up together when done like;
