Grilled Onions with Thyme and Cream

These creamy onions are a decadent topping for a burger or grilled steak.

• 
  
  3 medium yellow or red onions (or a mix), trimmed, peeled and sliced crosswise into 1/2-inch-thick rounds (12 slices total)
  
  


• 
  
  Olive oil, for brushing
  
  


• 
  
  Kosher salt and freshly ground black pepper
  
  


• 
  
  1/2 cup heavy cream
  
  


• 
  
  1 tsp. minced garlic
  
  


• 
  
  1 tsp. chopped fresh thyme
  
  

Position a rack in the center of the oven and heat the oven to 350°F.

Prepare a medium (350°F to 375°F) gas or charcoal grill fire. Brush the onion slices with oil and season with salt and pepper.

Grill the onion slices until grill marks form on one side, about 7 to 8 minutes. Flip the slices and continue to grill until tender, about 7 to 8 minutes more. Stack the onions on a large piece of foil, wrap the onions up, and let them sit for 10 minutes to soften further.

In a small bowl, combine the cream, garlic, thyme, 1/4 tsp. salt, and 1/4 tsp. pepper.

Arrange the onion slices in a snug single layer in 1 large or 2 small shallow baking dishes. Drizzle with the cream mixture. Bake until hot, about 10 minutes.
