Guinness Beef Sliders

Ingredients

Sandwiches

1 Tbsp. butter

8 oz. sliced mushrooms

½ vidalia onion, sliced

¼ c. Guinness

1 package sandwich rolls (I used King's Hawaiian Savory Butter Rolls)

¾ lb. sliced roast beef

6 slices swiss cheese

Glaze

1 bottle Guinness (or use the remainder of the bottle used for mushrooms & onions)

1 stick butter

¼ c. brown sugar

1 Tbsp. dried mustard

1 tsp. onion powder

2 cloves garlic, minced

Instructions

In a medium skillet, melt butter over medium-high heat. Add mushrooms, onions and ¼ c. Guinness and saute until liquid is absorbed.

Prepare glaze by combining all ingredients in a medium saucepan.

Bring mixture to a boil, then lower heat slightly and cook until thickened. (*Mixture should be reduced by at least half - when in doubt, reduce it a little more!)

Assemble sandwiches by slicing rolls in half, then filling with roast beef, sautéed mushrooms & onions, and swiss cheese.

Pour glaze evenly over sandwiches.

Bake, uncovered, at 350 degrees for 30 minutes.
