I had a craving for this sauce a few days ago but didn’t have any steaks. First world problems. I took a trip to my local grocery store in hopes of finding a couple marked down meats. Sadly, no good mark downs were found…but there was a flat iron steak that caught my attention. It was $9.99/lb which is $5 over budget. The sell by date was just 2 days away, so I knew it would be marked down the next morning. So I walked away crossing my fingers hoping fate would come through.
Fast forward 18 hours…my sought after flat iron steak was indeed not sold and was now 40% off! I snapped it up. At about 2 lbs it was a little over $13, not exactly cheap, but I knew it’d be good! I estimated it would serve 6 people – $2.16/person.
Step 1: Marinate the heck out of it! I am not the type of cook that measures ingredients unless I’m baking, or trying to be mindful of blog readers. I didn’t measure the marinade ingredients but I’ll make educated guesses. Start with a small mixing bowl and gallon size ziploc. I also bought a small t-bone steak so I added that to marinate with the flat iron steak.
Marinade Ingredients:
Dump them all together in a bowl
1/3 c dijon mustard (Trader Joe’s has CHEAP mustards!)
1/4 c mixed fresh chopped herbs – I used what I had growing in my container garden, thyme, rosemary, basil. I added dried oregano to the party.
2 t smoked paprika
1/2 t salt
1/2 t pepper
6 minced garlic cloves, I used the jarred stuff
2 jalapeños seeded and minced (I wouldn’t normally add these, but my little jalapeño plant grew them and I was just tickled to have anything grow)
1 t crushed pepper flakes
1/4 vegetable oil, you can use olive if you want, you might need a little more to thin out the marinade
Mix it all up, add your meat to the zipbloc bag, and pour it in. Be sure all the surfaces are covered. I marinated my steaks for about 48 hrs. After that I grilled them up! While they were grilling I started on the Gorgonzola Steak Sauce with Mushrooms and Bleu Cheese!
Sadly, I forgot to take a picture of the chunk of Trader Joe’s Gorgonzola, but I think you can imagine what it looks like! You can also use a straight up bleu cheese. They sell a pretty good already crumbled bleu cheese which would save you a little prep time.
Gorgonzola Steak Sauce with Mushrooms and Onions
1 large yellow sweet onion, thinly sliced
8 oz package of mushrooms, I’m partial to baby bellas, but white button mushrooms are fine too, thinly slice all of them
3 garlic cloves, minced
1/2 stick butter
1/4 t pepper
1/4 t salt
1 c heavy cream
1 1/3 c roughly chopped gorgonzola
I use a cast iron pan for most of my cooking. Heat it to medium-low, add onions, mushrooms, garlic, and butter. It takes a little time to get the veggies to soften. You don’t want to turn the heat up because you don’t need them to brown, just soften. Give it a good 15 min, stir every few minutes.
Once they’re soft add the salt and pepper, mix. Then the cup of heavy cream, you can turn the heat up a little bit. Let it get nice and bubbly!! You have to be a little patient while it thickens.
Once it resembles more of a sauce and less of a liquid you can add the crumbled gorgonzola or bleu cheese. Give it another minute or two, then remove from the heat. The cheese should be nicely melted into the sauce.
Spoon over your steak and try not to lick your plate!
