Time 55m

Yield 4 serving(s)

Number Of Ingredients 4

4 medium onions, peeled but left whole (baseball size)
4 teaspoons beef bouillon granules
1 1/2-2 teaspoons Worcestershire sauce
2 tablespoons butter

Steps:

  • Preheat oven to 400F or get a heap of coals glowing in your grill.
  • Carefully make 8 cuts down to, but not through the root end of each onion. To keep from cutting too far, it helps to put the onion inside a canning ring.
  • Working with one onion at a time, place an onion onto a square of heavy duty aluminum foil.
  • Very gently, push your finger into the top of the onion, to loosen the wedges enough to pour the bouillon granules into the center of the onion.
  • Drizzle the onion with 1/4 - 1/2 teaspoons Worcestershire sauce.
  • Smear 1/2 tablespoon of butter on top of the onion and into the cuts.
  • Gather the corners of the foil and wrap tightly. It will look like a giant hershey kiss.
  • To bake in the oven:.
  • Place all wrapped onions into a baking dish so that they will stay upright.
  • Roast in a 400F oven for 45 to 70 minutes or until soft.
  • To roast on a grill:.
  • Place the onions, individually on the grill grate. Rotate the location of the onions occasionally, being careful to keep them upright. Roast in a covered, hot grill 45 to 70 minutes or until soft.

CAPTAIN BLUE'S GRILL-ROASTED ONIONS



Captain Blue's Grill-Roasted Onions image

This is my husband's recipe. The onion, steamed in its own juices, comes out very mild and sweet. Prep time refers to the slicing time after they're done cooking. And, careful, they're slippery...

Provided by Titanium Chef

Categories     Vegetable

Time 35m

Yield 2 Servings per onion

Number Of Ingredients 2

onion (all skin intact)
seasoning (we use Lowry's Seasoned Salt)

Steps:

  • Place the onions on BBQ grill.
  • Roast 30 minutes- gas grill, middle shelf; charcoal, indirect heat.
  • Remove from grill onto disposable surface (there will be lots of carbon), cut the bottom off the onion and the soft, steamed interior should come out easily, leaving behind the charred skin layers.
  • Remove to clean plate.
  • Slice/ chop the onions and toss with seasonings.
  • (We serve them over buttered baked potatoes and top with grated cheddar cheese, fresh ground pepper and Tabasco. We stick a clean, food-use-only non-anodized aluminum nail or tent stake through the stem / tail ends of the onion before it goes on the grill. We find that it helps with even heat distribution - it works great for potatoes too.)

Tips for Roasting or Grilling Whole Onions:

  • Choose the Right Onions: Select firm, medium-sized yellow or white onions for roasting or grilling. Avoid using large onions as they may take longer to cook.
  • Prepare the Onions: Cut off the onion's root end and remove the papery outer skin. Leave the onion intact and unpeeled to keep it moist during cooking.
  • Season the Onions: Drizzle the onions with olive oil and sprinkle them with salt, pepper, and any other desired seasonings. You can also add herbs like thyme, rosemary, or sage for extra flavor.
  • Roast or Grill the Onions: Place the prepared onions on a baking sheet or grill grate. Roast them in a preheated oven at 400°F (200°C) for 45-60 minutes, or grill them over medium heat for 20-30 minutes, turning occasionally.
  • Check for Doneness: Insert a sharp knife or skewer into the center of an onion. If it slides in easily, the onion is cooked. If not, continue cooking for a few more minutes.
  • Let the Onions Cool: Once the onions are cooked, remove them from the oven or grill and let them cool slightly before handling.
  • Serve and Enjoy: Roasted or grilled whole onions can be served as a side dish, appetizer, or main course. You can also use them in various recipes, such as salads, soups, and stews.
