Peel 2 medium onions and cut a thin slice from the bottom and top of each one. Scoop out a 1-inch deep hole from the top of each onion. Place onions, top sides up, in a 2-qt. microwave-safe dish with a lid. Add 1 beef bouillon cube and ½ Tbsp butter to shallow hole in each onion; cover with lid. Microwave, covered, at HIGH for 8 to 10 minutes or until onion is tender. Garnish each with fresh parsley sprig and pepper, if desired.
Recommend only Vidalia or Texas Sweets for this recipe.
Be sure to use a microwave-safe lid only; plastic wrap will melt.
If you’d rather grill, wrap each filled-and-topped onion in heavy-duty aluminum foil (or a couple layers of regular aluminum foil). Grill over high heat (400 to 450 degrees) 15 to 20 minutes or until tender.
