We’ve been keeping our eye out and finding great deals on whole beef tenderloins. We trim them up and decided to make filet mignon steaks out of the last one we picked up. The bourbon garlic butter elevates these steaks to gourmet flavor status.

Ingredients for Bourbon Garlic Butter Tenderloin Steaks:

  • Beef Tenderloin Steaks ~ are a great choice for a tender and juicy grilled steak. 
  • Mushrooms ~ White button mushrooms pair really well with steak.
  • Onion ~ Yellow onions, sliced into small pieces with cook quickly with the mushrooms and make a great addition to grilled steaks.
  • Olive Oil ~ For coating the vegetables.
  • Butter ~ Use real butter to make the base for the sauce that adds delicious flavor to the smoky steaks.
  • Fresh Garlic Cloves ~ Makes the most flavorful butter.
  • Bourbon ~ Just a splash adds a depth of flavor to the grilled steaks, you won’t taste the alcohol – I promise.
  • Brown Sugar ~ Caramelizes on the steaks with the garlic for amazing flavor.
  • Green Chile Powder ~ Our new favorite ingredient. We ordered from Spiceology, if you don’t have it, smoked paprika is a great substitute, but slightly different flavor.
  • Kosher Salt
  • Coarse Ground Pepper

How to Grill Bourbon Garlic Butter Tenderloin Steaks:

  • Set tenderloin steaks out to come to room temperature. Pat dry with paper towels. 
  • If mushrooms are large, slice in half. Cut onion into bite sized pieces.
  • Toss mushrooms and onion with olive oil, salt and pepper in a bowl.
  • Thread onto skewers. We used rosemary stems from our garden but bamboo or steel skewers work just as well.

  • Make the garlic butter by melting butter in a small pan over low heat. Toss in minced garlic and cook, stirring often until garlic is toasted. Do not leave the pan unattended, the garlic can easily burn and you’ll have to start over. Stir in bourbon.
  • Remove from heat and cool about 5 minutes. 
  • Stir in brown sugar, green chile powder, salt and pepper and stir until combined and sugar is melted.
