Tender beef tenderloin is stuffed with a savory mixture of mushrooms, green onions, garlic, parsley, and blue cheese, then roasted to perfection. An impressive and elegant main dish for holidays or special occasions.
Preheat the oven to 425℉. Spray a small roasting pan or rimmed cookie sheet with nonstick spray.
Melt butter in large skillet. Sauté the onion, mushrooms, garlic and parsley, just until mushrooms are softened.
Make a slit down the middle of the tenderloin (without cutting it into two pieces) and stuff mushroom mixture inside. Sprinkle the blue cheese over the mushrooms. Pull the slit closed and secure with toothpicks.
Brush the tenderloin with melted butter and bake 30 to 40 minutes, or until desired degree of doneness is obtained. Slice into 6 portions and serve immediately.
Notes
For medium, pull it out of the oven at 130 to 135 degrees F., and let it rest for 5 minutes. For medium rare, pull it out of the oven at 125 to 130 degrees F.
If preparing this recipe as GLUTEN FREE, be sure to sub in a soft cheese that is GF (such as goat). Blue Cheese tends to be iffy on whether or not it's GF.
If you have a smaller piece of tenderloin, this recipe will work just as well. Make less of a mushroom mixture and continue with the recipe as instructed. Baking time will be a bit less.
