Copycat Panera White Cheddar & Steak Paninis, made from 30 minute Instant Pot Roast Beef

Copycat Panera Steak & White Cheddar Panini

In an unexpected twist, I fell in love with the Steak & White Cheddar Panini at Panera Bread. See, I have another “go-to” sandwich but when I was out with a friend, I followed her lead. Yeah, I’m a rule breaker these days! A rebel! It was so good, I’m glad I got out of my “rut” and I recreated it here, for you. So here’s my Copycat Panera Steak & White Cheddar Panini.

The funny thing about this Copycat Panera White Cheddar & Steak Panini is that when I ordered it at Panera, I didn’t really look through the menu. I usually order Panera’s Turkey & Artichoke Panini, so I didn’t know until later that my old standby had been taken off the menu. That was probably for the best because I needed to grieve when I found out. Alone. I worked through that grief and recreated that Turkey & Artichoke Panini, too. So now, you are covered with two different Panera sandwiches.

About Copycat Panera Steak & White Cheddar Panini:

Panera describes their Steak & White Cheddar Panini as “Seared steak, pickled red onions, Vermont white cheddar and horseradish sauce all grilled on Artisan Ciabatta.” It all sounds pretty simple but the flavors, all together are just outstanding. And while it might sound like a lot of “sharp” flavors with the red onions, sharp Cheddar and horseradish, it’s not. It’s really a nice combination.

Especially in a Panini. I do love a good Panini. What is it about pressing all the ingredients together and heating them up that makes those sandwiches so good? Well, part of it is the beautiful texture of the bread and that warm toasty crustiness, but the rest…maybe magic?

Of course, it seemed the perfect thing to make Copycat Panera Steak & White Cheddar Paninis with my friend Rosanne when she came over for a day of cooking. It was just right, seeing as she’s the one who introduced me. Best of all, Rosanne stopped by Panera on the way here and picked up the actual Panera rolls. How’s that for a great friend? If you don’t have a friend like mine, don’t have a Panera or don’t want to buy the rolls, look for a nice Ciabatta, a good hoagie type roll or French rolls will work, too.

Making Copycat Panera Steak & White Cheddar Panini:

Other than the beef, the rest of the sandwich is really about assembly. You can go homemade or store-bought on some of the ingredients. You can make or buy your Pickled Red Onions. I always have a jar in my fridge because I use them a lot, they’re so easy & they are the perfect thing to use up the rest of that Red Onion you might have left from something else. You can buy or make your Horseradish Sauce. I have a recipe for Horseradish Sauce, too, but we bought ours. Cut the recipe way back if you make it; you just need a little for the sandwiches.

The beef, though is a bit of a different story. I suppose you could buy it from the deli, one of their roast beef and just have them slice it a bit thicker than usual, about 3/8ths of an inch thick, but for me, that’s a bit pricey. But if you’re going to cook your own beef for your Panera Steak & White Cheddar Panini, it can made with just about any steak or roast. This is an ideal recipe to use a little leftover steak in, and an ideal one to cook a little extra steak just so you have enough to make this sandwich. I chose to use the 30 Minute Roast Beef I made in my Instant Pot. I keep sayin’ it: I love my Instant Pot!

If you don’t have a Panini Press, grill your sandwich in a pan, cast iron is great, and add another pan on top. Weigh it down with a big can of tomatoes or something else that’s heavy. Easy peasy!n I usually put a layer of foil between the top pan and the bottom of whatever pan I’m pressing with just to keep things nice and clean. I have a gas stove so the bottoms of my pans are never pristine.

Saving Money:

So now, fess up! Do you go to Panera, and do you have a “go-to” item that you order? Something you can’t live without? My old fave? The Turkey Artichoke Panini. (Please don’t tell it I’ve been cheating!) Update: that sandwich has been discontinued! Here’s my Copycat Panera Turkey Artichoke Panini. I’ve always been a fan of Panera’s but there is no doubt that like so many restaurants, they’re getting pricier. I might have to do more copycatting!

The best way to save money on your Copycat Panera Steak & White Cheddar Panini is to not be too particular about getting the exact ingredients and make a loose interpretation. While it was fun to make these with actual Panera rolls, that isn’t the cheapest way to go – although it wasn’t as expensive compared to the actual sandwich.

And of course, the beef you use is going to make a big difference. Using a small roast saves a lot of cost over using steak. You can buy roasts from rump to round to sirloin, all for the fraction of the cost that you can buy the actual steak (from the same part of the animal) for. And it doesn’t seem to matter if you are going for a grocery store or butcher beef, the roasts all seem to be less per pound.

I think it is probably cheaper to buy a little jar of horseradish that you can mix with some mayo rather than a bottle of actual horseradish sauce. The jars of prepared horseradish usually keep for a good long time in the fridge and then you can use them to whip up a little horseradish sauce as you wish, without worrying about it going bad. And of course, the red onions are a pittance to make.

    Here is Panera’s very own website with the detailed ingredients of things that go into the sandwich in question.—white-cheddar.html

    The ingredients copied and pasted from this website are listed below.
    What is surprising right of the bet is the sheer amount of things that go into the very said sandwich, and even more so the plethora
    of the ingredients that are as such not a foods per se. Panear prides itself with transparency of their ingredients – good.
    They also proudly say the food should be whole and tasty. Bravo but looking at the list below I kind of cringe on many things
    that are there.
    If you think of the Steak sandwich that has as a basic ingredients: Steak, bread, onion and horse radish you could
    this easily translate to the following list of ingrdeients:
    Bread – flour, water, yasts, salt, amen.
    Steak – meat, heat, salt, pepper, amen.
    Onion – onion, vinegar, water, sugar,amen.
    Horse radish sauce – horse radish, eggs, oil, sugar, salt vinegar amen.

    Why in heaven this list below is so long an has so many mysterious ingredients that no company that prides
    itself with healthy food should dump in it for no reason. Why is it pack with all kinds of gums, cultures, enzymes,
    and stuff like that. There is erally no reason. Please Panera keep it simple if you read this as they often do.

    Detailed Ingredients
    Artisan Ciabatta (Enriched Flour (Wheat Flour, Malted Barley Flour, Niacin, Reduced Iron, Thiamine Mononitrate, Riboflavin, Enzyme [Corn], Folic Acid), Water, White Whole Wheat Flour, Olive Oil Blend (Extra Virgin Olive Oil, Canola Oil), Salt, Dough Improver (Wheat Gluten, Malted Wheat Flour, Deactivated Yeast, Microbial Enzymes, Ascorbic Acid), Yeast (Yeast, Sorbitan Monostearate, Ascorbic Acid), Beef Sirloin (Beef Sirloin, Water, Vegetable Seasoning [Vegetables Carrot, Celery, Onion), Yeast Extract, Salt, Cane Sugar, Dried Potato, Natural Flavor, Onion Powder, Spice Extractives {Oleoresin Black Pepper, Oleoresin Celery}], Corn Starch, Steak Seasoning Blend [Spice, Dehydrated Garlic, Sea Salt, Canola Oil], Sea Salt, Smoke Flavor, Black Pepper), Horseradish Sauce (Soybean Oil, Water, Prepared Horseradish [Horseradish, Distilled Vinegar, Salt], Egg Yolks, Distilled Vinegar, Corn Starch, Salt, Sugar, Xanthan Gum, Rosemary Extract, Natural Flavor [Mustard Oil]), Sharp White Cheddar Cheese (Pasteurized Milk, Cheese Cultures, Salt, Microbial Enzymes), Pickled Red Onions (Red Onions, Sugar, Water, White Wine Vinegar, Distilled Vinegar, Calcium Chloride, Sea Salt)

    • I must have missed some of my comment notifications, and again, sorry for the late reply! I’m not a huge sandwich eater but I do love paninis. They just elevate the whole grilled cheese idea!

    • I love French Dips and made them, too!! These were really good, though! Maybe I should have made them into French Dips and served them with the au jus! I’m always about trying new restaurants and places I’ve never been but as far as a chain, I think Panera does a pretty good job.
