Name: Butter- and Herb-Roasted Red Onions
Prep time: 15 minutes
Total time: 1 hour 15 minutes
Yield: Makes 6
Ingredients: 6 medium red onions (about 7 ounces each), peeled, cut vertically into 6 wedges to within 1/2 inch of bottom; 1/2 cup (1 stick) butter, room temperature; 4 teaspoons minced fresh rosemary; 1 tablespoon chopped fresh Italian parsley; 2 teaspoons fresh lemon juice

This pretty side dish (the onions open up like flowers) would be great alongside steak or roast chicken.

TEST-KITCHEN TIP:

This simple recipe has endless variations. Here are three to try: After they come out of the oven, top the onions with a little crumbled blue cheese, sprinkle a mixture of crumbled cooked bacon and grated Parmesan on top, or whisk a little Dijon mustard and garlic into the herb butter before starting.
