Ingredients
For the steak coating
- ½ cup all-purpose flour
- 1 teaspoon salt
For cooking
- 3 tablespoons vegetable oil
- 2 pounds round sandwich steak
For the mushroom gravy
- 1 sweet onion, chopped
- ½ pound mushrooms, sliced
- 1 can (10 oz) beef consommé
- 1 cup water, divided
- ¼ cup ketchup
- 1 teaspoon mustard
- 2 tablespoons cornstarch
- Salt and pepper to taste
- 2 tablespoons fresh parsley, chopped (optional garnish)
Instructions
Prepare the steak
- 1 In a shallow bowl, stir together ½ cup flour and 1 teaspoon salt until well combined. This seasoned flour mixture will create a beautiful golden crust on your steak while also helping to thicken the gravy later.
- 2 Dredge each piece of steak in the flour mixture, pressing gently to ensure the coating adheres well to both sides. The flour coating should be even but not too thick – you want it to enhance the steak, not overpower it.
Sear the steak
- 3 Heat 3 tablespoons vegetable oil in a large cast iron skillet or heavy-bottomed pan over medium-high heat until the oil shimmers and is hot but not smoking. This temperature is crucial for achieving that perfect golden-brown sear.
- 4 Carefully place the floured steaks in the hot oil and brown for 2-3 minutes per side until golden brown and crispy. Don’t overcrowd the pan – work in batches if necessary. The goal here is to develop flavor and texture, not to cook the steak completely through.
- 5 Remove the browned steaks from the skillet and set aside on a plate. Don’t worry about cleaning the pan – those browned bits (called fond) will add incredible flavor to your gravy.
Create the mushroom gravy
- 6 To the same skillet with all those delicious browned bits, add the chopped onions and sliced mushrooms. The residual heat will start cooking them immediately, and they’ll pick up all that concentrated steak flavor from the bottom of the pan.
- 7 Stir in the beef consommé, ½ cup water, ¼ cup ketchup, and 1 teaspoon mustard. The ketchup adds a subtle sweetness that balances the savory elements perfectly, while the mustard provides a gentle tang. Reduce heat to medium-low and let the mixture come to a gentle simmer.
Thicken and finish
- 8 In a small bowl, whisk together 2 tablespoons cornstarch and the remaining ½ cup water until completely smooth with no lumps. This slurry will thicken your gravy to the perfect consistency.
- 9 Add the cornstarch mixture to the skillet and whisk constantly to combine. Cook for 7 minutes, whisking frequently, until the gravy thickens and coats the back of a spoon. The mixture should be glossy and smooth.
- 10 Return the browned steaks to the skillet, nestling them into the gravy. Heat for another 5 minutes, or until the steaks are heated through and have absorbed some of that incredible gravy flavor. Season with salt and pepper to taste, and sprinkle with fresh chopped parsley if desired. Serve immediately while hot.
Recommended Equipment and Kitchen Tools
Recommended Tools (for best results)
- Cast iron skillet or heavy-bottomed pan – Essential for achieving that perfect sear and maintaining even heat throughout the cooking process. The heavy bottom prevents hot spots that could burn your steak.
- Instant-read thermometer – While not strictly necessary for this recipe, it’s invaluable for checking that your steak reaches the desired internal temperature without overcooking.
- Whisk – Critical for creating a smooth, lump-free gravy. A good whisk incorporates the cornstarch slurry seamlessly and prevents clumping.
- Tongs – Makes flipping and handling the steak much easier and safer than using a fork, which can pierce the meat and release juices.
Helpful Upgrades
- Digital kitchen scale – For more precise measurements of flour and cornstarch, ensuring consistent results every time you make this recipe.
- Silicone spatula – Perfect for scraping up all those flavorful browned bits from the bottom of the pan when making the gravy.
- Quality cutting board – A sturdy board makes prep work safer and more efficient when chopping onions and slicing mushrooms.
Nice-to-Have Options
- Splatter screen – Keeps your stovetop clean during the searing process while still allowing moisture to escape.
- Gravy separator – If you want to remove excess fat from the finished gravy for a cleaner presentation.

Gluten-Free Adaptation
- Replace ½ cup all-purpose flour with ½ cup gluten-free flour blend (1:1 ratio works perfectly)
