Garlic Steak With Mushrooms and Onion-Roasted Potatoes

My husband and I tried this sample at the local grocery store, and instantly fell in love with it. However, when I made this at home I wasn’t as pleased. A few of my co-workers also made this dish and loved it, so that’s why I’m posting it up for  my readers to try. The original recipe can be found here.

Prep: 10 minutes
Cook: 20-25 minutes


  • 2 tbsp extra-virgin olive oil
  • 1 tbsp minced garlic
  • 1 tsp Montreal steak seasoning
  • 1/2 tsp salt
  • 1 1/2 lb top sirloin steak
  • 1/3 cup butter
  • 8 oz whole baby portabella mushrooms 
  • 1 (20-oz) package refrigerated red potato wedges
  • 1 packet onion soup mix (about 1 oz)
  • 2 tbsp extra-virgin olive oil


  1. Preheat oven to 400°F. 
  2. Combine in medium bowl, oil, garlic, steak seasoning, and salt. Cut steak into four portions; add to garlic mixture, turning to coat (wash hands). Let stand 10 minutes.
  3. Combine onion soup and extra-virgin olive oil in a bowl; whisk together well. Then add potato wedges. Spread in single layer on baking sheet. Bake 10 minutes. 
  4. Preheat large sauté pan on medium-high 2–3 minutes. Place steaks and garlic mixture in pan; cook 5 minutes (do not turn).
  5. Reduce heat to medium and turn steaks; cook 6–8 more minutes or until 145°F (for medium-rare).
  6. Turn potatoes; bake 10 more minutes or until tender.
  7. Add butter, turning steaks to coat. Remove steaks and cover to keep warm. Add mushrooms to pan and cover; cook 5–7 minutes or until tender. 
  8. Plate both potatoes and steak, and enjoy! 

Side Suggestions: salad, steamed green beans, crusty breaad
