Pearl Onions Are Simply Baby Onions. Because They Are Young, Pearl Onions Don’t Have The Sharpness Of Flavor Found In Full-Grown Onions. Instead, They Have A Natural Sweetness That Pairs Well With The Saltiness Of The Fresh Parmesan Cheese. Anytime You Are Cooking Steaks On The Grill, Toss These In The Oven Because They Are Heavenly Together. If Red Meat Isn’t Your Thing, Serve Them Alongside Grilled Chicken, Pork, Or Seafood.
