Strip Steak with Onion Sauce

This Strip Steak with Onion Sauce is better than going to a steak house! Perfectly cooked strip steak with a melt in your mouth, sweet onion sauce!


A Steakhouse Worthy Recipe For Cooking At Home

Steak. Nothing says guy food like a big juicy steak. Caramelized onions are one of my favorite toppings, so are these oyster mushrooms…but then I found a recipe for onion sauce. Onion sauce? I had to check it out. This onion sauce is sort of like caramelized onions…but better.

The onions are cooked down in the same way, low and slow, but these onions get some white wine and cream to make it more of a sauce than just caramelized onions. And trust me when I say that it’s worth the half and hour it takes to make these.

How To Make Onion Sauce

Start out by cooking down a whole bunch of sliced onions in a large skillet with thyme and a bay leaf. The large your skillet is the less time it will take to cook down the onions, so grab the biggest one you have.


After about 25 minutes they’ll look like this…super sweet and brown and perfectly caramelized.


Next add white wine, beef broth and cream to make the sauce, then cover and keep warm until the steaks are ready. We chose strip steaks for this recipe, but you can use this onion sauce on any type of steak you have. Flank steak, skirt steak, sirloin and oh yes – filet. This onion sauce is PERFECT for topping a beautiful filet mignon.


What Else Can I Use This Onion Sauce On?

Of course we don’t want to leave anything out…because this onion sauce is the bomb, my friends. You’re going to want to be adding it to everything!

  • Grilled Chicken
  • Hamburgers
  • Use as a sandwich topping
  • Taco topping
  • Stir into chicken salad

      Betsey, I really don’t have the nutritional info – working on getting that for a new recipe card, I’ll let you know when I do! I know you can go to certain sites like calorie counter and plug in recipe information if you want to try that!
