Capital Grille Porcini Rubbed Steak

I’m about to make a bold statement. A very bold statement, but I think this Copycat Capital Grille Porcini Rubbed Delmonico with Balsamic Glaze might have been the BEST  at home steak I have ever made.

Capital Grille Copycat Recipe

The idea came from good old Capital Grille and their famous Porcini Rubbed Delmonico with 12-Year Aged Balsamic.

While some beef fanatics might argue that a truly good piece of meat needs to no rub, crust or drizzle (and they may be correct), the porcini rubbed delmonico has won the hearts of food critics everywhere.

And now you might even see it grace the Capital Grille menu as the porcini rubbed ribeye, strip steak or even t-bone.

What is a Delmonico Cut?

The dish originates from the Delmonico Steak, which actually refers to the method of preparation rather than the cut. Made famous by Delmonico’s in Manhattan, there is still much controversy as to what cut of beef was actually used.

Fast forward to today and it is most commonly from the short loin section. A New York strip is cut from the short loin so it is the perfect choice for this dish, but really any cut of beef will do. You can even do a tenderloin or T-bone, like I’ve used here.

You will see the same terminology and preparation at the famous steakhouses of Chicago, which are often the toughest of critics.

Now that Capital Grille makes a porcini rubbed bone-in ribeye, I supposed it is totally acceptable to use the same rub on just about any cut of beef you wish. It probably tastes equally as tasty on thick-cut cast iron pork chops too!

Porcini Rub

Sweet, spicy and salty all combine and play well together to form a mouth watering entree worthy of a special occasion. And while even serving this dish at home is above my average “weeknight budget” is still less than what I’d pay at the restaurant, making me the winner.

dried porcini mushrooms

Capital Grille uses dried porcini mushrooms and grinds them to a fine dust, which is the obvious part. I grilled (pun intended) my last server into sharing all of his secrets of what goes into the rest of the delectable crust.

If you have trouble finding dried porcini mushrooms, give dried portobello or oyster mushrooms a whirl.

When grinding the dried mushrooms, make sure to let the powder sit and settle before opening your food processor. Take it from me- you’ll end up with a mushroom dust that will make you sneeze like crazy!

Some dried mushrooms can still be a little damp. If they don’t grind all the way, take out the large bits by hand or run it through a colander. A few larger pieces won’t hurt the recipe. No worries.

After making the rub, gently press it into the steak and allow it to sit so it cakes on using the natural juices of the steak to make a paste. Some might fall off when you pick it up, that is fine.

Balsamic Glaze

Aged balsamic is another item that your run-of-the-mill grocer may not stock. Twelve year aged balsamic is delicious and packed with sweet flavor, but will run you $30 for a small bottle.

Instead I used a middle grade balsamic vinegar and made a reduction which intensifies the flavor, but saves your wallet. Don’t get sucked into the $13 bottle of premade reduction at the grocery store, it is ridiculously overpriced and how often are you really using an aged balsamic?

Pan Fried

When most individuals associate steak with the grill, but in actuality, you won’t find Chef de Fancy Restaurant out back flipping your steak on a Weber with his “Kiss the Cook” apron.

They are either pan fried, cooktop grilled or broiled. A properly seasoned cast iron skillet allows the taste of the crust/rub to remain without being overpowered by the char of a grill. If you don’t have time to season your own and want the care to be a little simpler, buy a Le Creuset pre seasoned pan.

I have both. I love both. The only difference in mine is size (and price). If you aren’t in the market for cast iron you can always broil, grill or use a large frying pan.

How to Pan Fry

The secret to pan frying steak is to have a really HOT pan with a really DRY steak.

You are taking advantage of the Maillard reaction, a chemical process of browning which changes the flavor profile of your meat. Use little to no oil in order to make this happen.

The crust (bark) of the porcini rub will burn a little since it has sugars in it. Trust me when I say, this is what you are looking for. A burnt crust with a ruby red medium rare interior.

If you prefer your steak well done, choose a thinner cut or place it in the oven after the initial sear. If you like it rare or medium rare, then you’ll be fine with a thicker cut.

Sear on each side for 3-4 minutes, 5 if it is super thick. Don’t touch it, then flip. At the end and after being removed from heat, top with butter to moisten and rest.

How to Cut A T-Bone

Many restaurants will just serve you a t-bone on a plate and that is fine, but the really fancy ones will present you with the cut and then carve it for you either tableside or in the back.

The smaller side contains a tenderloin filet and the larger side, a NY strip.

  1. Allow your steak to rest fully before carving.
  2. On the large side, cut along the bone to remove the NY strip side.
  3. Cut into strips along the grain.
  4. On the smaller side, carve off the filet and serve it whole.
  5. Plate in a fan fashion along the bone to display the full cut.

Copycat Capital Grille Porcini Rubbed Delmonico is the perfect home date night dinner. An easy recipe filled with robust steak flavors and sweet balsamic reduction sauce.
Prep Time: 10 minutes
Cook Time: 10 minutes
Total Time: 20 minutes
Servings: 4



  • Place dehydrated porcini mushrooms into your food processor and grind until they are nothing but dust. Word to the wise… allow to sit for a few minutes before opening or else you might get a mushroom dust bomb in your kitchen.
  • In a small bowl combine ground porcini mushrooms with sea salt, pepper, crushed red pepper and sugar, mix to make the rub.
  • Remove steaks from the fridge. Rub into steaks evenly and on both sides. Allow to rest and marinate for 20 minutes so it forms a paste and sticks well.
  • When ready to cook, heat seasoned cast iron to just before smoking point. Depending on the size you might need to cook steaks two at a time to avoid overcrowding the pan. Heat over HIGH heat and turn on the fans to prevent the smoke detector from going off.
  • Sear on each side for 3 (medium rare) to 8 (well done) minutes depending on desired temperature and thickness of meat. These were 1 1/2 inches and rare- I cooked them for 3 1/2 minutes per side. When cooking do not move the steak around, keep it in the same place except to flip. In contrast to cooking other pieces of meat in cast iron, do not baste with the butter. Basting will wear away at that beautiful crust you worked so hard on. If you have someone that requests "no pink", you might be better off baking at 400 for 4-5 minutes instead of searing for the full 8 minutes. You don't want the outside to burn.
  • About 1 minute before you remove the steaks, add 1 tablespoon of butter directly to the top to melted over meat. If you add it too early, it can burn, so wait until right before are ready to remove it.
  • Remove steaks from the skillet and allow to rest for at least 5 minutes. Meat holds heat well so do not worry about them getting cold. Resting helps the juices (and flavor) to reabsorb back into the meat instead of ending up on your cutting board.
  • When plating, drizzle with balsamic reduction sauce and serve.

    I’ve been searching for this recipe for a long time. My husband thinks Capital Grille is hands down the best steak he ever had. I’ve tried this recipe with the substitution with Monk Fruit sugar and Stevia brown sugar. The whole family loves it! Thank you for this recipe!!!!

  2. Hi Jessica, the recipe is great I will try it! I prefer no pink you mentioned to sear first then bake or bake for the whole 4-5 minutes each side in the oven the whole time in the cast iron pan? What would be the timing for no pink, medium well done? Would 2 minutes on stove each side then 4-5 mins in oven each side would work?or just in the oven 4-5 mins in the oven each side would work? Please let me know, Thanks!

    1. Hi Mary- it really depends on the size of your cut, but just to be sure, use an instant read thermometer and check the doneness. There is a chart in the post to know when it is done.

    I used a filet mignon and it turned out fantastic. I also made a red wine fig balsamic reduction for the sauce. I posted on my page the dish… Porcini Rubbed Filet Mignon resting on a roasted Portabella Mushroom with a Red Wine Fig Balsamic reduction, roasted White Truffle Potatoes and roasted Brussel Sprouts. I’d post a pic… but it doesn’t allow me.

    1. You can, BUT the crust won’t caramelize the same way- it reallys needs to all make contact with a heat element and while you could do it grilling, you’ll risk losing some of the crust.

    1. Not if you are using a well seasoned cast iron, nope. If not, you can add a thin layer- like just wipe it with an oiled paper towel.

    When and how do you use the butter; the recipe doesn’t say, but it’s listed as an ingredient

    1. Hi Gillian, thanks for pointing that out- I just updated this recipe and forgot to pop the butter back in. You put it on top of the steaks right before removing them from the skillet.

    1. Hi Claude! I literally changed it this afternoon when I realized it was a typo. I re-made the recipe over the weekend to take few new photos. 8 ounces of dried mushrooms would be 8 -16 standard packages. One package of dehydrated mushrooms is about 1 ounce and that is all you need! Hope that helps!

      1. Ahh, ok. I printed it out a while back and went to make it using the website instead the other day and noticed something was off. Kinda messed it up but I’ll go with the original next time. Thanks!

        1. Hi Claude- the only thing I changed was the amount of dried mushrooms because it was an error. If you used 8 ounces, like it stated before, you’d be buying 1-16 packages of dried mushrooms. I also removed the olive oil because it wasn’t needed.

    Made this for dinner on the grill tonight. It was yummy and it was $49 dollars less than dining at The Capital Grille !

    We have been trying new recipes since COVID-19 has us staying home instead of dining out and this was FANTASTIC. It was an adventure to make and it was delicious. Hands down will do it again. My wife and I shared the steak and both enjoyed it. Thanks!

    1. So glad you enjoyed it- our anniversary is on Thursday and since we can’t go out we’ll be preparing this too. I hope you try a few others as well and thank you for taking time to come back and let us know. It means a lot.

    Outstanding! A personal favorite at Capital Grill, as well as at home. Tonight will probably the 10th time I’ve used the recipe. Thank you!

    1. Thanks, Al! And thank you for stopping by to let us now. It means a lot to take time out of your day to leave us a nice comment. 🙂

    I made this for my Birthday dinner. It was absolutely delicious. I did add a tsp of cornstarch to thicken balsamic topping and cut the ingredients for the rub. I also used Delmonico steaks as they are my favorite. This will definitely be made again. It was fantastic. Thanks for sharing!
