Smothered Steak Skillet - cooking recipe

Ingredients

Garlic Smashed Potatoes
2 lbs red potatoes
1/2 cup milk
1/4 cup cream
3 tablespoons butter
salt, to taste
black pepper, to taste
1/4 cup garlic clove
olive oil
Sauteed Onions and Mushrooms
1/2 lb yellow onion, peeled and cut into 1/4 inch julienne strips
1/2 lb sliced mushrooms
2 tablespoons butter
granulated garlic, to taste
salt and fresh cracked black pepper, to taste
Sirloin Steak Skillet
1 (2 3/4 lb) sirloin steaks (see note in description about rubs and marinades) or (2 3/4 lb) smaller cut sirloin steaks, seasoned to taste (see note in description about rubs and marinades)
sauteed mushrooms or onion, see recipe
garlic mashed potatoes, see recipe
8 slices mozzarella cheese

Preparation

Garlic Mashed Potatoes: Place a single layer of garlic cloves on a sheet of heavy-duty aluminum foil and drizzle olive oil, just enough to coat.; wrap tightly.
Roast in 400 degree F preheated oven for approximately 45 minutes or until soft. (This can easily be done in a toaster oven; watch carefully and will take less time.) Unwrap and let cool until touchable. Peel cloves and mash with potatoes when they are ready.
Wash and rinse potatoes under cold water. In large sauce pot, bring potatoes to a slow boil for approximately 20 minutes. The exact time depends on the size of the potatoes used. For faster cooking, cut into smaller pieces. Remove from heat and drain in colander.
In pan or bowl, combine potatoes, peeled and roasted garlic cloves and all other ingredients and smash with a potato masher; adjust milk and seasonings. Return smashed potatoes to low heat, if necessary to keep warm. (See my suggestion in description about a cast iron pan.).
Sauteed Onions and Mushrooms: Melt butter in skillet over medium heat and add onions and seasonings. Saute and stir until lightly caramelized. Add sliced mushrooms and stir, as needed to avoid burning, until hot.
Sirloin Steak Skillet: Grill steaks to desired degree of doneness; slice against the grain. Melt the slices of mozzarella cheese over each shingled steak. Top with onions and mushrooms, and serve with smashed potatoes on the side.
