Ingredients
Sandwiches
- 1 Tbsp. butter
- 8 oz. sliced mushrooms
- 1/2 vidalia onion sliced
- 1/4 c. Guinness
- 1 package sandwich rolls I used King's Hawaiian Savory Butter Rolls
- 3/4 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
- 1/4 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 1/4 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.
