Turkey Tenderloin with Creamed Spinach and Mashed Sweet Potatoes

Turkey Tenderloin with Creamed Spinach and Mashed Sweet Potatoes- This recipe a lighter version of steak house classics. Instead of using beef filet mignon, I use turkey tenderloin for a steak and pair it with a delicious sauce made with shallots and demi glace. I pair the tenderloin with cream cheese creamed spinach and mashed sweet potatoes.

  • In a bowl mix salt, pepper and savory seasoning, evenly season tenderloin on both sides. Sit out for 15 minutes at room temperature. Heat a grill pan over medium high heat, add oil then add tenderloin and cook for 3 minutes each side. Then pop in the oven for 5 minutes. Remove tenderloins and sit to the side. Pour chicken stock in grill pan and with a wooden spoon scrape pan to pick up brown bits. Heat a small skillet over medium heat, once hot add butter then cook shallots and garlic for 1 minute. Add chicken stock and demi-glace and cook until demi-glace is melted. Taste and adjust seasoning, sit to the side.
  • To make creamed spinach heat a pot over medium heat add oil and spinach cook until spinach is wilted, then add remaining ingredients and bring to a boil. Transfer to a serving bowl.
  • Pop sweet potatoes in the oven on the grate for 1 hour until tender. Remove from oven and cut a small slit down the middle to release the steam. Grab a towel and take sweet potatoes and scoop out the flesh into a bowl, add butter, salt and thyme. Mix together until butter is melted, taste and adjust seasoning.
  • To assemble add sweet potatoes to center of plate, place one tenderloin in the center and ladle 2 tablespoons of sauce over top and garnish with chives.


This recipe works well with filet mignon too. If you are a pescatarian follow the recipe as is just use a salmon steak or tuna. You do not need to let the fish sit for 15 minutes after seasoning.
