grilled steak with caramelized onions and cream sauce

last updated on October 30, 2026

This grilled steak with caramelized onions and cream sauce is all you need this summer! This dish looks extra fancy, but is surprisingly easy to make! Plus it tastes incredible so it’s a win-win all around. 

When I first made this cream sauce it was so good I wanted to drink it all! Or at least put it on everything I ate. It is made from shallots and garlic, with broth, heavy cream, and brown sugar. Plus the secret ingredient of a little bit of dijon mustard! I am telling you this cream sauce will be your new favorite.

The steaks I used are Sprout’s 100% Grass-fed Angus Steaks! They are pasture-raised in the US on family farms so they are fresh and tasty. I love going to Sprouts for great cuts of meat, and fresh produce! The caramelized onions I used are sweet Vidalia onions from Sprouts. They caramelize beautifully and pair perfectly with the steak. I love doing a quick caramelized onions. To do this I add butter to a pan with my chopped onions. After they have started to cook down and stick to the pan, add a splash of water. This will help the onions begin to caramelize. Continue cooking for a couple minutes and add another splash of water. Continue this until the onions are caramelized! It should only take about 15 minutes. 

As for the order, begin by cooking the caramelized onions first, then the sauce, then the steak. Grilling the steak only takes a few minutes so its best to do that last! Also this dish isn’t complete without a handful of arugula. Arugula’s peppery taste matches beautifully with the sweet notes of the sauce and onions! So don’t forget the arugula!
