Grilling season is upon us, and there's no better way to celebrate than with a flavorful grass-fed flap steak, cooked to perfection and accompanied by savory sautéed onions and mushrooms. Using Acabonac Farms' grass-fed flap steak, this dish is not only mouth-watering but also showcases the benefits of regenerative agriculture.


  • 2 lbs Acabonac Farms grass-fed flap steak
  • 2 tbsp olive oil, divided
  • Salt and pepper, to taste
  • 1 large onion, thinly sliced
  • 8 oz mushrooms, sliced
  • 2 cloves garlic, minced
  • 1/4 cup red wine (optional)
  • 2 tbsp fresh parsley, chopped (for garnish)


  1. Preheat your grill to medium-high heat. While the grill is heating up, take your grass-fed flap steak out of the refrigerator and allow it to come to room temperature for about 30 minutes. This will ensure even cooking.
  2. Pat the flap steak dry with paper towels and brush it with 1 tablespoon of olive oil. Season both sides generously with salt and pepper.
  3. Place the flap steak on the preheated grill and cook for 4-5 minutes per side for medium-rare, or until it reaches your desired level of doneness. Remove the steak from the grill and let it rest for 5-10 minutes before slicing against the grain.
  4. While the steak is resting, heat the remaining 1 tablespoon of olive oil in a large skillet over medium heat. Add the onion and cook until softened and golden brown, about 5 minutes.
  5. Add the mushrooms to the skillet and cook until they release their moisture and start to brown, about 5-7 minutes. Stir in the garlic and cook for an additional 1-2 minutes until fragrant.
  6. If using, deglaze the skillet with red wine, scraping up any browned bits from the bottom. Cook for 2-3 minutes to allow the wine to reduce and the flavors to meld.
  7. To serve, slice the rested flap steak against the grain and top with the sautéed onions and mushrooms. Garnish with fresh parsley and enjoy.
