That special something only grilled steak provides

There’s something about a grilled steak that nails it every single time in a way that poultry and pork just can’t reproduce. A great grilled chicken or pork chop will satisfy me every time and can really be done spectacularly, but beef, beef is where my mouth starts to salivate and  I really get excited about the possibilities.

Keep it simple with great beef.

Beef, in my opinion, is the simplest of proteins, needing little to jazz up the inherent flavors. As long as the cut is cared for properly, it holds a perfectly fine flavor all it’s own with little more than a sprinkle of salt.

Needless to say, when heading to the butcher for a weeknight grill out, I snagged a fresh 2-pound tri-tip off the counter. I saw them arranging their cuts without asking what else was around back. It’s not a cut I get to experiment with in my region due to its lack of popularity. So, rarely do I find it not in a vacuum sealed bag with a Santa Maria seasoning already working it’s way in, inspired by its humble rise to fame in California.

What exactly is a tri-tip steak?

We can play with rib-eyes and strips for days, but grilling a fresh tri-tip? Oh, lucky day. For $26.57 I grabbed my chunk of meat and set out to make supper.

The tri-tip is a triangular cut from the bottom sirloin of the cow. It isn’t always the most tender of cuts, but is long and lean and with a little love can produce a fantastic meal.

Tri-tip isn’t as hot and fast as a thin steak, so give it a little time over the heat to allow the muscle to really break down without seizing up and add time in for a good rest before slicing thin and diagonally on a bias against the grain.

Cutting it against the grain, after it has properly rested, is very important! Otherwise you might wonder why I recommend tri-tip in the first place. And, since the tri-tip has two grains, this is like a pop quiz – the answer, you will need to rotate halfway through cutting to continue to slice across the grain!

What are button mushrooms?

Ok, this is probably a regional thing. Button mushrooms are the same mushroom as crimini and portabella mushrooms. But hold on, why not just say crimini or portabella?

Good question. Because each name describes a different life stage of the mushroom. Crimini are the little babies, buttons the mid-life crisis, and portabella are the grand old dames of the mushroom’s life cycle.

Now you know. But just to complicate matters, sometimes the button are just called “brown” mushrooms, or even just called mushrooms, as if they hold the torch for the entire realm of mushrooms.

Can I use other kinds of mushrooms?

If you want to get fancy, and in this case that means stepping up and paying a bit more, then try using other mushrooms like morels or shitakes, chanterelles, and yellow trumpets. Most of those are classified as “wild” mushrooms but truth be told they are grown in controlled conditions as well on farms.

Which means they should be a lot cheaper than they are, but oh well. They do taste great though and will fancy things up a bit if you feel like going there.

Now on to the grilled tri-tip with mushrooms….

  1. This sounds absolutely fantastic! Thank you for sharing at the Delicious Dishes Recipe Party!

    1. You are 100% correct and I have no idea what I was thinking when I included that with the recipe! I created the butter and had it on the platter along with some other non-Whol30 options for my friends (who aren’t doing it and love carbs) and I totally spaced and kept it in for this. A drizzle of infused ghee would be perfect! Thank you 😀
