Instructions

  1. Step 1: Heat 2 tbsp extra virgin olive oil in a large skillet over medium-high heat. Add 1 lb beef tenderloin tips seasoned with 1/2 tsp sea salt and 1/4 tsp black pepper. Sauté for 5-6 minutes, stirring occasionally, until browned and cooked to desired doneness. Remove beef from skillet and set aside.
  2. Step 2: In the same skillet, add the remaining 1 tbsp olive oil and 4 minced garlic cloves. Sauté for 30 seconds until fragrant, being careful not to burn the garlic.
  3. Step 3: Add 8 oz sliced cremini mushrooms and 1/2 tsp sea salt. Cook for 6-7 minutes until mushrooms release their moisture and begin to brown.
  4. Step 4: Add 5 cups fresh baby spinach to the skillet and cook, stirring, for 2-3 minutes until wilted and tender.
  5. Step 5: Return the beef tenderloin tips to the skillet with the mushroom and spinach medley. Stir to combine and heat through for 1-2 minutes. Remove from heat and garnish with 2 tbsp chopped fresh parsley before serving.
