- Begin by mixing all the patty ingredients together and forming small patties approximately 3/4 inch thick.
- Create a cozy bed of sliced onions and mushrooms in the slow cooker.
- In a skillet, brown the steak patties on both sides. For an extra burst of flavor, we recommend this step, although you can place the raw patties directly into the slow cooker if you’re pressed for time.
- Place the browned patties on top of the onions and mushrooms in the slow cooker.
- Mix all the remaining ingredients (except cornstarch) to create a delectable sauce, then pour it over the meat and vegetables. Cover and let it simmer on low for 5 hours, allowing the flavors to meld and intensify.
- After 5 hours, remove the patties. Turn the slow cooker to high, whisk in the cornstarch, and let the magic happen as the sauce thickens.
- Return the patties to the slow cooker, allowing them to soak up the rich sauce before serving.
