- 4 round steaks 1 inch thick, 7-8 oz each, can also use blade or chuck
- 2 pounds potatoes small potatoes or cut into chunks
- ½ pound mushrooms sliced
- 1 large onions sliced
- 1 tablespoon garlic minced
- 1 can tomato paste (5.5-6 oz)
- 5.5-6 oz low sodium soy sauce about ¾ cup
- 5.5-6 oz water or broth, about ¾ cup
- ¼ cup cornstarch or potato starch
- oil
- 1 tblsp dried thyme or rosemary more or less to taste
- salt to taste
- pepper to taste
Preheat your oven to 300 degrees. Prepare a roasting pan with cooking spray. Set aside.
Pat steaks dry with paper towels. Season with salt and pepper.
Dump corn or potato starch on to a shallow dish. Coat each steak on both sides and shake off excess. Use more corn or potato starch if necessary.
In a large skillet, over medium to medium high heat, pour oil and wait until the oil shimmers or a drop of water flicked in it dances.
When oil is ready add steaks to the skillet and cook until browned, around 4 minutes per side. Lay browned steaks on to a plate. Remove skillet from heat and wipe clean.
Open and add tomato paste to skillet. We use the empty tomato paste can to measure ¾ cup of soy sauce and water or broth. Add to skillet and stir until incorporated.
Add onions, mushrooms, potatoes, garlic, thyme. Heat until boiling and pour into your prepared roasting pan. Place steaks on top.
Cover and bake in your oven for 2 hours.
Uncover and continue to bake for 30 minutes longer. Steaks should be nice and brown and so tender.
Season potato mixture with salt and pepper to taste. Serve immediately.
- Coat Evenly: Lightly dust the steak with cornstarch on all sides before searing for a golden crust and naturally thickened sauce.
- Hot Skillet = Juicy Steak: Always start with a hot pan to sear and lock in flavor.
- Cover for Tenderness: Keep the pan tightly covered while baking to trap steam and soften the meat; uncover near the end to reduce and brown.
- Mind the Salt: Use low-sodium soy sauce and broth for better control. If using regular, taste before adding more salt.
