Ingredients
For the Hamburger Steaks
- 2 Tablespoons olive oil
- 1 ½ lbs. ground beef (85% lean)
- 4 Tablespoons frozen butter (shredded)
- ½ cup yellow onion (very finely minced)
- 2 teaspoons yellow mustard
- 3 cloves garlic (minced)
- Salt and Pepper, to taste
For the Onion Gravy
- 2 yellow onions (sliced into ¾ inch strings)
- 3 Tablespoons cold unsalted butter (divided)
- 1 cup chicken broth
- 1 cup beef broth
- 1 teaspoon onion powder
- ½ teaspoon garlic powder
- ¼ cup cold water
- 3 Tablespoons corn starch
Instructions
- Prepare the Steaks: Gently combine the minced onions, shredded frozen butter, garlic, mustard, and the ground beef. Be careful not to overwork the meat to keep the steaks tender.
- Shape and Chill: Form the mixture into evenly sized oval-shaped steaks. Refrigerate the shaped steaks for 15 minutes while preparing the remaining ingredients.
- Season the Steaks: Remove the steaks from the fridge and season each side generously with salt and pepper.
- Sear the Steaks: Heat olive oil in a large skillet over medium-high heat. Add the steaks and sear each side for 2-3 minutes, handling them gently to maintain their shape and juiciness. Once seared, set them aside.
- Cook the Onions: Reduce heat to medium-low, then melt 2 tablespoons of butter in the skillet. Add the sliced onions and cook for 15-20 minutes until they soften and start to caramelize, stirring occasionally to prevent burning.
- Add Broths and Spices: Pour in the chicken broth and beef broth, then sprinkle in the onion powder and garlic powder. Scrape the bottom of the skillet with a silicone spatula to loosen brown bits from the meat for extra flavor in the gravy.
- Prepare Cornstarch Slurry: In a small bowl, mix the cold water and cornstarch until completely smooth and combined.
- Thicken the Gravy: Bring the gravy mixture to a boil, then whisk in the cornstarch slurry. Allow the gravy to thicken, then reduce heat to medium-low.
- Simmer the Steaks: Return the steaks to the skillet, spoon the gravy over them, and cover. Let cook for 10 minutes or until the internal temperature reaches 160°F, ensuring the steaks are cooked through.
- Finish the Gravy: Stir in the remaining 1 tablespoon of cold butter into the gravy for a smooth and velvety finish, a technique inspired by professional chefs.
- Serve: Sprinkle chopped parsley over the steaks and gravy. Serve hot alongside mashed potatoes and roasted carrots for a complete meal.
Notes
- Do not overwork the ground beef mixture to prevent tough hamburger steaks.
- Caramelizing the onions slowly is key to developing a rich and flavorful gravy.
- The final butter swirl in the gravy adds a luxurious texture and glossy appearance.
- Use a meat thermometer to check that the internal temperature of the steaks reaches 160°F for safe consumption.
- Leftover gravy can be stored in the fridge for up to 3 days and reheated gently.
