Better-Than-Gravy Creamed Pearl Onions

Step 1
Partially thaw onions for 10 minutes, then thinly slice crosswise into rounds. Set in a colander and let thaw completely. Drain and spread on a paper towel-lined tray. Pat dry with paper towels.

Step 2
Heat oil in a large skillet over medium-high heat. Add onions and 1/4 teaspoon kosher salt; cook, stirring frequently, until liquid evaporates and onions are lightly browned and slightly crisp, about 10 minutes.

Step 3
Melt butter in a saucepan over medium heat. Stir in flour until smooth; cook and stir until pale golden, about 30 seconds. Gradually whisk in milk. Increase heat to medium-high and cook, whisking frequently, until sauce is bubbling, thickened, and smooth, about 8 minutes. Add 3/4 cup parsley, sherry, paprika, cloves, and cooked onions; season to taste with salt and pepper. Transfer to 3 buttered 2-cup broiler-safe baking dishes or 1 buttered 2-quart baking dish.

Step 4
Preheat the oven's broiler to high. Sprinkle panko evenly over onion mixture.

Step 5
Broil 5 inches from heat source until panko is golden brown, 1 to 2 minutes. Watch closely to avoid burning panko. Garnish with more parsley.
