Mushroom Pesto & Asparagus Flank Steak Roll

I originally wanted to try this recipe with a beef tenderloin; however, they were out of tenderloin today, so I tried this with flank steak and it really worked ~ very tasty! I made one flank steak roll with asparagus and the other without.

 Mushroom Pesto & Asparagus Flank Steak Roll


  • flank steaks, about 2.5 pounds total
  • 2 tablespoons Dijon mustard
  • oil of your choice for drizzle (I used avocado oil)
  • 8-10 asparagus stalks
  • Cooking/Butcher’s Twine
  • sea salt & ground pepper

Mushroom Pesto:

  • 6 ounces mushrooms (I used 3 ounces each of shiitakes & bellas)
  • 1/4 cup parsley, roughly chopped
  • 1/8 cup pine nuts
  • 2 garlic cloves
  • 3 tablespoons of your favorite oil (I used 2T avocado oil and 1T black truffle oil)
  • 1 tablespoon capers
  • 1 teaspoon sea salt


  1. In a large baking dish, season both sides of each steak liberally with salt and pepper. Drizzle with oil. Cover. Refrigerate for 2-4 hours.
  2. Preheat oven to 400 degrees.
  3. Pound out steak between 2 pieces of parchment paper. Flank steak doesn’t pound out like chicken does, but you can get it to between 1/4 inch and a 1/2 inch.
  4. In a food processor, blend pesto ingredients until smooth.
  5. Spread the pesto over each steak.
  6. Snap the hard ends off of the asparagus. Cut the remaing stalks in half and then line up (side-by-side) on the pesto.
  7. Roll up each steak lengthwise with the smaller end rolling toward the larger end. Secure with twine about every two inches.
  8. Place in baking dish, seam side down. Brush with Dijon mustard.
  9. Bake for 50-60 minutes…until desired doneness. Let rest for 5 minutes. Remove twine. Slice about 1 inch pieces. Serve.
  10. Enjoy!

  1. Made this for dinner tonight and it was delicious. I cut the baking time down to 40 minutes and I think I will cut it to 35 minutes next time. Other than that – perfect! And, my hard-to-please hubby was impressed.

    My youngest daughter and I made this for dinner on Monday. Not only was it a fun and interesting dish to make (daughter loved pounding out the flank steak), it tasted great! I too will decrease the cooking time and I look forward to cooking this again.
