Keto Steak Medallions In Asiago Cream Sauce with Peppers And Mushrooms

186 ratings

In just one skillet, you can make a full meal with protein, vegetables, and a fatty, rich asiago cream sauce! The steak medallions are cut from a delicate beef tenderloin. You can cook your steak to any level of doneness; but, for the best flavor, a medium-rare steak would be perfect. If you’d like additional sauce with your meal, just follow the Carb Manager Asiago Cream Sauce recipe!

Recipe Steps

steps 11

33 min

  • Step 1

    Prepare the vegetables by slicing the bell peppers and mushrooms. Thin, wide cuts will be best for this skillet dish, but you can cut them in any way you like. Set these aside.
    Step 1
  • Step 2

    Lay your cuts of tenderloin on a flat surface. How many cuts you have does not matter, as these will be sliced later on. On the exposed side, sprinkle HALF the salt and pepper and ALL the onion and garlic powder.
    Step 2
  • Step 3

    Heat the first amount of olive oil in a wide skillet on high heat. Place the tenderloins seasoned side down in the oil. Sprinkle the remaining salt and pepper over the bare side of the meat.
    Step 3
  • Step 4

    Cook the tenderloins to your preferred doneness. For this recipe, it’s suggested to cook to medium-rare or slightly more on the rare side at 5-6 minutes per side. You may cook longer for a more done steak. Keep in mind this steak will be returned to a hot skillet later on and cook more.
    Step 4
  • Step 5

    Transfer the cooked steaks to a clean surface. Leave the skillet on a medium-low heat, and add the second amount of olive oil to the pan. Toss in the peppers and mushrooms, coating them in the oil.
    Step 5
  • Step 6

    Cook the vegetable for about 4-5 minutes. Stir in the italian seasoning. The veggies should be soft with slightly golden edges. Transfer the veggies to a clean bowl or plate for later use.
    Step 6
  • Step 7

    Now that the steak has had some time to rest, slice it into thin slices, as pictured.
    Step 7
  • Step 8

    Wipe your skillet clean. Return it to the stove for a final time on a very low heat. Melt the butter in the skillet, then whisk in the cream until the liquids have emulsified.
    Step 8
  • Step 9

    Whisk the asiago cheese into the cream sauce. You can turn the heat up slightly to help the cheese melt, without bringing the cream to a simmer.
    Step 9
  • Step 10

    Return all vegetable and steak to the sauce. Toss the ingredients so everything is coated in the asiago sauce. If you’d like to cook the steak through a little more, place a lid over the skillet and bring the heat up to a gentle simmer. Let everything cook until all ingredients are heated through and you’re happy with the doneness of your steak.
    Step 10
  • Step 11

    Divide the skillet amongst 2 plates and enjoy!

              Yes. Can switch the protein with most meats.

              This has to be one of the best meals I have ever made. Thank you for this amazing dish! I did find that, using my cast-iron skillet, I only had to cook the steaks on medium. They turned out absolutely perfect!😋

                I’m looking forward to making this but I’m finding it difficult to find the Asiago cheese. Which supermarket stocks it please or what would be a suitable substitute. Thanks

                  It's probably not in the regular dairy (cheese) section, does your store have a specialty cheese section?

                  Not sure if you have an Aldi near you, but they usually have it. It’s typically in a wedge. We just shred up what we need before hand. I’ve also subbed this with parm too, and it’s still yummy. Good luck!

                I used petite sirloin and added a small amount of white wine to deglaze the pan. My husband and daughter both got seconds. It was so good!

                  I made this tonight for dinner - It’s absolutely fabulous! The asiago and pepper - the scent of it all - this is one of my all time favorites! I forgot to add the stars - a full 5!

                        What is the substitute for asiago cheese?

                          Maybe Grana Padano or Pecorino Romano. I’d try GP first.

                        Delicious!! No peppers but added onion. Next time cuttting back on the salt.(cheese is salty.) definitely a new favorite 👍🏼

                          I had no peppers but used sliced onions and no Fontina but shaved parmigiana. Still amazingly good, especially on a winter day.

                            First time cooking beef tenderloin in a recipe and this dish was so delicious. I did double the last 3 ingredients for more sauce however, as another member suggested.

                              This is fabulous. Next time I think I will just use mushrooms and pile it on the steak. Was so so good!

                                This was so good. After reading all the comments first, I made tiny adjustments. I doubled the mushrooms because we really like mushrooms. I doubled the last three ingredients too for extra sauce because my husband wanted some sauce to put on flat egg pasta noodles. I didn’t add anything else to this meal for me. It was filling enough for me. Very quick to prep and make.

                                  Yes this app NEEDS a recipe editor so you can change amounts of ingredients or remove some you don’t use. Apps less expensive have this feature. Sucks to have to manually create a new one when a tweak is more efficient.

                                    You can if it's already in My Foods (click the ❤ in the upper right corner) or if you go ahead and log the original recipe, then edit it. In either of these places, when you tap the three dots in the upper right corner, one of the options will be to edit custom recipe. You can delete and add ingredients there. What I long for is that each ingredient had its macro count. Then, you could adjust how much of each ingredient you want.

                                  SO GOOD! My picky husband, who is usually the cook around here, has requested this meal 4-5 days a week. lol I think he was serious. It's a keeper!
