1 pound 93% lean ground beef
2 tablespoons plus 2 1/4 teaspoons olive oil, divided
2 teaspoons Worcestershire sauce
3/4 teaspoon kosher salt, divided
3/4 teaspoon black pepper, divided
1/2 cup finely chopped sweet onion
8 ounces cremini mushrooms, sliced
1 1/2 teaspoons all-purpose flour
1/2 cup unsalted beef stock
1 ounce Gruyère cheese, shredded (about 1/4 cup)
How to Make It
Combine beef, 2 1/4 teaspoons oil, Worcestershire, 1/2 teaspoon salt, and 1/2 teaspoon pepper in a bowl; mix with hands. Divide into 4 portions, shaping each into a 4-inch patty.
Heat a skillet over medium-high heat. Add 1 tablespoon oil to pan. Add patties to pan; cook 3 minutes on each side. Remove patties from pan. Add remaining 1 tablespoon oil to pan; swirl to coat. Add onion and mushrooms to pan; cook 6 minutes or until mushrooms brown. Sprinkle with flour, remaining 1/4 teaspoon salt, and remaining 1/4 teaspoon pepper; cook 2 minutes. Add stock to pan; cook 1 minute or until thickened and slightly reduced, stirring frequently. Return patties to pan, and spoon onion mixture over patties. Sprinkle evenly with cheese. Cover; cook 3 minutes or until cheese melts.
Badly in need of more seasoning--herbs, wine, something. And like another reviewer, I cut the oil drastically. It's just not needed and butter would have given a better flavor to the vegetables. It's okay, but really dull.
I received this recipe via Cooking Light Diet. My family loved this. The best part was how easy it was to make. I served with an arugula salad and am still feeling light on my feet but very satisfied. Thanks CL!
I made this recipe for 2 of us made 3 patties not 4 so we have one leftover. 1/4 pound patty didn't sound like much of a dinner. Very good, of course more cheese and it would have been even better. I didn't used all the olive oil called for in the patties and used less salt. I served with a salad.
I was able to cut out a lot of the olive oil. I didn't add any to the hamburger mix. And I only needed 1 Tablespoon for both the searing of the patties and the mushroom/onion mixture. The flavors were really good. Hubby liked it too. Next time I might add a teaspoon of mustard to the sauce. Easy to prepare. Will definitely make again. We had it with oven roasted potatoes. Would be good with mashed potatoes too.
