Perfect roast beef with demi-glace sauce is a dinner party worthy dish. A serious dinner party dish. For when you really want to impress. When you want to pull out all the stops.

It’s not hard. It’s done restaurant style. Do your prep and it will all come together. Big wow factor. Low stress factor. Not a bad combination.

A strip-loin means no bones to deal with either. I love prime rib. But I love this too. And it adds to the wow factor. Worth considering…

Demi-glace and reverse sear are what make this work

Demi-glace is what makes this work. It is one of the secret weapons in the high-end restaurant arsenal. Learn from them. Add it to your arsenal.

It’s real work to make but you can freeze it. Just pull it out when you need a flavour grenade to push your cooking into the stratosphere. Pretty flowery description. I know. But it’s that good.

The other key trick is reverse sear. Slow roasting the beef gets you the perfectly evenly done beef. None of this well done most of the way through and just right at the centre.

No chewing through grey beef just to get at that one good bite. All good. The whole way through. Add that to your arsenal too.

perfect roast beef with demi glace sauce

Ingredients

  • 1 3-4 lb striploin roast
  • 1/2 cup chicken or veal stock
  • 1 cup demi glace - recipe link below
  • fleur de sel optional but great little flavour bombs

Instructions

  • A couple hours before you start cooking, take your roast out of the fridge. Season with salt and coarsely ground pepper. Let it warm up a bit.
  • Pre-heat your to around 235F. Your oven swings and probably isn’t exactly right. You will be relying on your instant read thermometer so don’t worry too much about the exact oven temperature.
  • Place the roast in an roasting dish that can go from the oven to the stovetop. You want something that’s not too much bigger than the roast. Leave your big turkey roaster in the cupboard.
  • Slow-roast the beef for about 1 hour. A striploin isn’t a big thick hunk of beef so it will cook fairly quickly. After an hour start checking the internal temperature.
  • When the roast reaches 118F degrees (rare)/123F (medium rare)/128 (medium) remove the roast from the oven. It will rest while you heat up your oven for the final sear. It can sit for 30-45 minutes.
  • Turn your oven up to 475F.
  • After about 30 minutes, return your roast to the oven. Cook for 5 minutes. It should brown up nicely.
  • Remove the roast from the oven, take the roast out of the roasting pan and tent with foil.
  • Place the roasting pan on the stove over medium heat. Add the stock and scrape up any little golden bits.
  • Add the demi-glace and heat through. Strain through a fine mesh strainer to remove any solids.
  • Slice the roast across the grain (like you were cutting steaks from the roast). I like about 1/4 inch thick but do what works for you.
  • Serve the beef with a drizzle of the demi-glace.

Notes

Nutrition

This one is epic. Korean pork bone soup or gamjatang is an all day affair. Rainy day cooking. Hurry up and wait as it simmers away. But when it’s ready. What a great dinner on a rainy or cold winter night.

Gamjatang is pork bone soup that eats like a meal

It’s called pork bone soup but it’s more of a stew. Spicy, rich and delicious. Tender pork. Potatoes. Pork stock. Korean flavours. Tons of umami. Crazy good.

It’s really no different than making stew. There’s meat and potatoes and stock. Where it’s different is the seasonings. That is pure Korean.

Gochujang is like spicy miso

It’s a long list of ingredients. And they aren’t easy to find. Gochujang, gochugaru and doenjang you should be able to find pretty easily.

Gochujang is worth seeking out on it’s own. It’s used in a lot of Korean cooking. It’s like miso. Sort of. But with kick. Miso with Korean chili.

You can use it any time you want to add a little heat and Korean taste to a dish. Have you tried gochujang mayo yet?

Perilla leaves and perilla powder are tougher. But you can leave them out. Use chicken stock instead of making pork stock.

I’m not saying it will be the same I you don’t make make pork stock though. Gamjatang is a pork soup. Pork. More pork flavour is better pork flavour.
