My Best Tips
Here's what I've learned from making these countless times: slice that steak super thin and against the grain it makes such a difference! And don't skip the resting time we want those juices to stay put. Sometimes I'll add different toppings based on what's in season!
Mix It Up
Sometimes I swap the chimichurri for creamy blue cheese when I'm feeling fancy. My sourdough-loving friends adore these on crusty sourdough slices instead of baguette. And adding some peppery arugula on top? Pure magic!
Perfect Pairings
I love serving these at cocktail hour with a nice bold red wine. They're perfect for everything from holiday parties to game day gatherings. Sometimes I'll make a big platter for casual weekend snacking they disappear so fast!
Make Life Easy
Want to get ahead? Make your chimichurri and caramelize those onions the day before. Just save the toasting and assembly for the last minute. This way you can actually enjoy your party instead of being stuck in the kitchen!
