The Ultimate Steak Sandwich: Perfect for Father’s Day


Welcome to the first in what will hopefully be a series called, The Hermit Cooks.  The Hermit doesn’t get to cook really often because he leaves at 6AM and gets home at 6PM for his job.  But when he cooks. . . it’s AMAZING!!  His latest creation is the perfect meal for Father’s Day.

Or really, anyone who loves a perfectly cooked steak…

Let’s start at the beginning as all good stories do.

The Hermit is all about comfort food.  He watches youtube cooking videos obsessively, and whenever we have access to television, he usually flips it over to a cooking show.

I’m not sure where he dreamed up this particular combination, but you’ll be so happy he did.

Prepare the French Fries

Start by prepping the french fries.  Cut 4 russet potatoes into fry shapes and soak in a water bath for around 30 minutes.  Little hands are excellent for transferring the cut fries into the water.  We used a cold frying method of making the fries and found that it worked a lot better if the fries were cut a little thicker.

Chimichurri Sauce Love

While the fries are enjoying their bath, get started on the chimichurri sauce.

Assembling the sauce couldn’t be easier.  Throw onion, parsley, garlic, chili flakes, oil, and salt and pepper into the blender and blend until smooth.

You can obviously use a regular food processor, but we are in love with this Tupperware version.  We use it because electrical outlets are scarce in an old home like ours.

Once the chimichurri sauce is complete, it’s time to chop up your onions, garlic, and mushrooms.  They’ll get fried in butter for delicious steak toppings.

Question: What’s better than once sauce?  Two sauces.

Combine 3 parts mayo to one part sriracha sauce for a delicious counterpoint to the chimichurri.

Thick slabs of sourdough bread. . . yum!

Salt your steak and let it sit for 20-30 minutes.  Heat the pan to high.  Fry until your steak is medium rare to medium, let sit for 5-10 minutes, and cut into thin strips.  (You can fry it to well done, but true steak lovers probably won’t.)

Pro tip: cut against the grain of the steak for best results.

This particular batch of fries was baked in the oven.  Whether you deep fry or bake, the choice is yours and both are equally delicious.

Why are there both baked and deep fried fries in the post, you ask?  Because we went a little crazy with how many potatoes we cut.  You can never have too many, right?

Steak Sandwich Perfection

Now comes the fun part. . . assembling this deliciousness!!

Sourdough bread, sriracha mayo, chimicurri sauce, onions, mushrooms, garlic, and succulent steak all combine to make the ultimate steak sandwich.  Plate with crispy fries or your favourite fresh salad and enjoy!
