Seared Steak with Balsamic Red Spring Onions

Every once in a while I like to pick up a completely new to me ingredient, take it home and see what I can do with it. Recently I found some red spring onions at the grocery store and decided that they were too pretty to not bring home with me. Once I got home, I knew that I wanted to do something simple with them. Something to really showcase their beautiful color and flavor. Enter: Seared Steak with Balsamic Red Spring Onions.

My first inclination was to grill these whole. I love a good grilled onion. The char on them is my favorite part. I make several batches every year.

Mother nature, however, had other plans when it came to these spring onions. Like making it rain non stop. All. Day. Long.

We Pacific Northwesterners do do a lot of stuff in the rain. There is that ongoing joke that if we didn’t do anything in the rain then we wouldn’t ever do anything at all. But I draw the line at grilling in the pouring down rain.

I. Just. Can’t.

With grilling out of the question, I decided the next best thing to do would be to roast them. For this I cut off the green tops, but I didn’t throw them away.  And you shouldn’t either. You can totally use them for other things like stir fries, in salads and on top of baked potatoes in place of green onions. I even used them to garnish this dish.

After I cut off the tops, I cut off the root end of the onion and the cut the onions in half. Drizzled them with some balsamic, olive oil and salt and tossed them in the oven.

Next, I cooked a couple of New York strip boneless steaks using the cast iron steak method that I used in this post for Pan Seared Steak with Creamy Herbed Horseradish Sauce . With one minor change: when I put the steaks in the oven to cook, I scattered the partially roasted balsamic red spring onions around them to finish roasting while the steaks cooked.

You guys, it. was. heavenly.

The steak was perfectly cooked but the onions are the star of the show here. They aren’t too strong. They are slightly charred. Kind of sweet. And even cooked, the color of the spring onions is still just so pretty.

Almost too pretty to eat.

    Oh my! This is what I want for dinner! I love any kind of cooked onions, but grilled onions are my weakness. I would happily take these roasted onions on that delicious steak though!

    My daughter’s birthday is coming up, and when I asked her what she wanted she said “steak and cake”! This looks so yummy, and thank you for the steak cooking tip. I really haven’t mastered not cooking a steak to death, though I doggedly keep on trying.
    Looking forward to the spring onions in the farm share–I bet they’ll taste great this way!

    This looks perfect! Spring onions are delicious grilled! I have a grilled potato salad that is out of this world and I always triple the amount of onions that the original recipe called for. I’ve been know to grill in the rain a few times, I think I even have a picture of my husband outside grilling salmon burgers using our picnic table umbrella as a shield haha!
