Throw in the rest of the steak ingredients. Use your hands to mix gently for a couple of minutes until it starts to feel a bit sticky—this helps with shaping.

Split the mix evenly into 5 portions. Press them into firm ovals about 3/4 inch (around 1.6 cm) thick.

Heat up some oil on high in your skillet. Place the steaks in to cook for a minute or so on one side till browned, then carefully flip to brown the other. They'll still be raw inside. Transfer them to a plate.

If the pan seems a bit dry, splash in a little more oil. Toss in the chopped onion and garlic, cooking for 2 minutes until the onions look soft.

Dump the sliced mushrooms into the pan and stir them around for 2–3 minutes until golden and tender.

Turn the heat to medium. Melt the butter in the pan and stir in the flour. Cook for about 30 seconds, stirring all the time.

Slowly pour in the beef broth while stirring. When it's mostly smooth, whisk in the rest of the gravy ingredients.

Add the patties back into the gravy along with any juices from the plate. Let it all cook for 5–7 minutes till the gravy thickens. If it gets too thick, splash in some water.

Take the steaks out onto a dish. Taste the gravy and tweak the seasoning with salt and pepper if needed. Spoon the mushroom gravy over the steaks. It's amazing with mashed potatoes!
