A bold, steakhouse-worthy sauce, this Blue Cheese and Caramelized Onion Steak Sauce layers the sharp, creamy depth of melted blue cheese with the low-and-slow sweetness of caramelized onions. It comes together quickly on the stovetop and drapes beautifully over a seared Pre New York Strip, turning a weeknight dinner into something worth lingering over.
Total Time: 30 minutes
Servings: 2–4
Blue Cheese Steak Sauce Ingredients
1 Pre New York Strip steak (suggested pairing)
1 large yellow onion, thinly sliced
1 tablespoon unsalted butter
1 tablespoon olive oil
1/2 cup heavy cream
1/2 cup beef stock
7 ounces crumbled blue cheese
Instructions:
Heat butter and olive oil in a skillet over medium-low heat.
Add onion and cook, stirring occasionally, until deeply golden and soft, about 25 to 30 minutes.
Remove onions from pan and set aside.
In a small saucepan, heat heavy cream over medium-low heat, being careful not to scald it.
Stir in beef stock, then add blue cheese, stirring until cheese has melted and blue cheese steak sauce is smooth, about 5 minutes.
Reduce heat to low and continue to stir until sauce thickens slightly, about 3 to 5 more minutes.
Reserve a portion of caramelized onions for topping, then fold the remainder into the sauce and stir to combine.
Drizzle blue cheese steak sauce over prepared steak and top with reserved onions. Sauce will keep for 2 weeks in an airtight container in the refrigerator. Rewarm over low heat before serving.
