What's Cookin'? guest Patty Millay is back with the perfect March Madness recipe!. Check this out!  It's Patty's recipe for March Madness Seven Layer Steak Sandwich.
From Patty:
It's March in Kentucky and that brings a special type of competition known as March Madness!  People plan their lives and vacation around the upcoming college basketball games and assemble in mass to cheer on their favorite teams.  I am not a basketball fan but I do love many that are, so my role is to FEED them!  I got this recipe from my cousin and it's been very popular on the Internet lately.  I thought I'd give it a try to see if all the buzz was worth it.  I think we have a WINNER here!

2 (12-oz) sirloin or top loin steaks
Freshly ground salt and pepper
1 1/2 sticks unsalted butter
½ large yellow onion, chopped
2 cups button mushrooms, chopped
1 large sourdough bread bowl
5 slices cheddar cheese
1 cup baby spinach
8 strips cooked bacon
5 slices Provolone or Swiss cheese

Season each steak generously with salt and pepper, making sure to rub the salt and pepper into the sides of the steak.Using your heaviest skillet, heat 3 pats of butter until melted.  Lay one steaks in the pan and cook for about 3-4  minutes. Flip the steak, add one more pat of butter and baste while cooking another 3-4 minutes.   Set the steaks aside on a cutting board to rest.  Repeat this process with the second steak.Wipe out the skillet and heat the 3 pats of butter over medium-high heat. Add the onion and mushrooms and sauté, stirring constantly, until caramelized, about 20 minutes.  If this starts to get too dry during cooking, add a pat or 2 of extra butter.Using a serrated knife, slice the top off the bread and scoop out the insides to create a bread bowl. Nestle one steak into the bottom of the bread bowl. Layer the cheddar cheese evenly on top. Add the caramelized onions and mushrooms and use a spoon to spread them evenly over the cheese. Top with the spinach, then the bacon, then the Provolone or Swiss cheese.

Finally, put the second steak on top, tucking it under the lip of the bread bowl. Cover with the bread lid and wrap the entire loaf in foil. I didn't scrimp on the foil, I used about  4-5 layers tucked tightly to avoid any possibility of this bad boy drying out!

Place the wrapped sandwich on a baking dish.  Stack weights or large books on top cutting board to compress the sandwich.  Chill in the fridge for at least 5 hours.  I used three 10lb weights that I borrowed from Thing #2 and let mine chill for 24 hours.

Preheat the oven to 275˚F. Remove the foil from the sandwich and place it on a baking sheet. Bake for 30 minutes, until the bread is slightly crisp. Slice into wedges...mine was still cool in the center so I microwaved each slice for 1 minute to completely melt the cheese.  Brace yourself - this will smell heavenly!  I added a side of salt and pepper kettle chips and dill pickle spears then watched the hubs devour it!

This is the perfect make head sandwich for the big game.  My  crew loved it!   I hope yours does too!   GAME  ON!!!
