Ingredients

• 1.5 pounds boneless beef round steak
• 0.5 cups all-purpose flour
• 1 teaspoons salt
• 0.5 teaspoons black pepper
• 0.5 teaspoons garlic powder
• 3 tablespoons vegetable oil
• 1 large yellow onion
• 8 ounces white mushrooms
• 2 cups beef broth
• 1 tablespoons Worcestershire sauce
• 0.5 teaspoons dried thyme
• 1 tablespoons cornstarch
• 2 tablespoons water
• 2 tablespoons fresh parsley (optional, for garnish)

Directions

Step 1

Preheat the oven to 325°F (160°C).

Step 2

Trim the beef steak of excess fat and cut it into 4 equal portions. Use a meat mallet to tenderize the steak by pounding it to about 1/2-inch thickness.

Step 3

In a shallow dish, mix the flour, salt, black pepper, and garlic powder. Dredge each piece of steak in the flour mixture, ensuring it's evenly coated. Shake off any excess flour.

Step 4

In a large oven-safe skillet or Dutch oven, heat the vegetable oil over medium-high heat. Brown the steaks on both sides in batches (about 2–3 minutes per side), then transfer them to a plate and set aside.

Step 5

Thinly slice the onion and mushrooms. In the same skillet, add the onion and mushrooms. Cook for 5–7 minutes over medium heat, stirring occasionally, until the onions are softened and the mushrooms are browned.

Step 6

Pour the beef broth into the skillet, scraping the bottom of the pan to release any browned bits. Stir in the Worcestershire sauce and dried thyme.

Step 7

Return the browned steaks to the skillet, nestling them into the mushroom-onion mixture. Cover the skillet tightly with a lid or aluminum foil and transfer it to the preheated oven.

Step 8

Bake for 1 hour, or until the steak is fork-tender.

Step 9

While the steak is cooking, mix the cornstarch and water in a small bowl to create a slurry.

Step 10

Remove the skillet from the oven and return it to the stovetop over medium heat. Carefully remove the steaks and set them aside on a plate.

Step 11

Stir the cornstarch slurry into the mushroom-onion mixture and cook for 2–3 minutes, or until the gravy has thickened.

Step 12

Return the steaks to the skillet, spooning the gravy over the top to smother them. Cook for an additional minute to heat through.

Step 13

Garnish with chopped fresh parsley, if desired, and serve hot with mashed potatoes, rice, or your favorite side.
