These thick, beefy, prime rib sandwiches are made with tender prime rib, earthy roasted poblano peppers, spicy pepper jack cheese and quick garlicky mayo all topping crusty buns. Here is the recipe.
We're making some amazing Prime Rib Sandwiches in the Chili Pepper Madness kitchen today, my friends. We're talking comfort food extraordinaire.
These sandwiches are incredibly satisfying, and I'm sure you're going to love them.
If you have any leftover prime rib in your home from the holidays or other special occasion, this is one recipe you seriously need to make.
We have thin slices of prime rib piled high on crusty buns, topped with melty cheese, lots of roasted poblano chilies and a creamy garlic mayo, just for you.
We both took a first bite and sort of melted in our chairs from delicious awesomeness. But then again, they ARE made from super tender, amazing prime rib.
CRAY GOOD.
Making it is an easy enough thing. You'll chop up the cooked prime rib or cooked ribeye - I just did a rough chop on mine. Heat it up in a pan and add in a bit of stock and seasonings.
The stock will bring some delicious moisture to the finished sandwich, and will help infuse all those new seasonings.
Pop it onto a couple buns - I used crusty bolilo buns, though any thick bun will do - and top it with shredded pepper jack cheese and chopped roasted poblano peppers.
If you don't know how to roast a poblano pepper, instructions are below, or see here - How to Roast Chili Peppers.
Bake the newly stacked sandwiches for a few minutes to let the cheese get nice and melty and the crusts just slightly toasted. Top them with garlic mayo and BOOM! You will LOVE this sandwich!
Let's do this! How to make prime rib sandwiches, my way!
Prime Rib Sandwich Ingredients (with Roasted Poblanos and Garlic Mayo)
- Prime Rib. Yep, you'll need some prepared prime rib for this recipe, my friends. I'm using leftover prime rib from my Spice Rubbed Prime Rib Recipe, but use your favorite. This is perfect for leftovers, like smoked prime rib roast. Yum.
- Olive Oil. For heating the prime rib.
- Seasonings. I'm using Cajun seasonings, one of my favorite blends.
- Stock. Use beef stock or chicken stock.
- Poblano Pepper. We're going to roast it to pile onto the sandwich. Amazing.
- Cheese. I am using pepper jack cheese. Melted provolone cheese slices is delicious, too.
- Buns for Serving. I love large bolilo buns, but any crusty sandwich bread will do.
- FOR THE GARLIC MAYO. Mayonnaise and garlic powder.
How to Make Prime Rib Sandwiches - the Recipe Steps
Prepare Your Prime Rib. Roughly chop the prime rib and add it to a pan or skillet over medium heat with olive oil. Heat it through about a minute.
Add the Cajun seasoning and stock. Stir and simmer until the stock reduces and the prime rib is nicely coated with seasonings.
Roast the Poblano Pepper. Roast the poblano pepper over an open flame, flipping often, until the skin chars and blackens.
You can also roast it in the oven or broiler. See How to Roast Chili Peppers. Wrap the poblano in paper towel until it cools, then peel off the charred skins.
Finely dice the poblano.
Get the Sandwiches Ready. Heat the oven to 350 degrees F. Slice open the buns and stuff them with prime rib.
Top with shredded cheese and poblano peppers.
Set the sandwiches onto a baking sheet and bake them for 5 minutes to allow cheeses to melt and get the bread a bit crusty and golden brown.
Make the Garlic Mayo. Mix the mayo and garlic powder and top your sammiches! Enjoy!
Boom! Done, my friends! What do you think? It's the ultimate leftover prime rib sandwich. It is super quick and easy to make when you have leftovers.
Go for it! I hope you like it. Let me know how it turns out for you. Send pics! And as always, feel free to share.
I'm ready for my prime rib steak sandwich!
Recipe Tips & Notes
- The Prime Rib. As mentioned, leftovers are ideal for this recipe, but you can use other cuts of beef for this. Craving a good steak sandwich? Chop up some ribeye or filet mignon and cook them up in a pan to medium-rare. Proceed with the recipe! So good!
- The Garlic Mayo. I kept the mayo very simple with 2 ingredients. Feel free to include other components, such as sour cream for a creamier version, pinch of salt and pepper as needed, and other seasonings.
- Other Toppings. You can really vary this up as desired. I love a bit of arugula and horseradish cream sometimes, like this particular Prime Rib Sandwich Recipe with Horseradish Cream Sauce. Super tasty. Au jus would be wonderful here for dipping. Roasted garlic? Oh dang.

Michael Hultquist - Chili Pepper Madness says
Excellent! Thanks, Brent!!
brent says
gonna make it then rate it.
I have poor man's prime rib: cross rib roast. And a crock pot. And a cast iron to sear edges. And all the ingredients you have. And all day tomorrow.
You hand chunked cooked prime rib. I will probably shred or slice it after cooking.
But either way, beautiful.
My question good sir: I've have mixed and matched pork, beef, and chicken stocks for recipes but have NEVER used chicken in a beef dish. I have some fresh stock. Is it noticeable? For the amount the recipe calls for it seems like it would not matter. Or does the chicken complement?
thank you.
Michael Hultquist - Chili Pepper Madness says
Thanks, Brent. The chicken stock is a bit lighter, IMO, though you can use beef to good flavor here. No problem at all. I hope you enjoy it.
Hollis Ramsey says
Simply AWESOME, Mike. Thanks from a sammich lover! (IMO, the sandwich is the ultimate food delivery method.) I cook for myself only, so I'll try to find a ribeye to cook up — Any suggestions on how best to cook a ribeye for a sammich?
Michael Hultquist - Chili Pepper Madness says
Sounds great, Hollis. Ribeye, yes! One of my favorites. I love just salt and pepper and maybe a bit of garlic seasoning, then either sear it in a pan to temp, or a reverse sear on the grill. So good both ways. Enjoy!
