INGREDIENTS

■ 2 teaspoons vegetable oil
■ 1 pound ground sirloin
■ 1 medium yellow onion, diced
■ 3 cloves garlic, minced
■ 1 cup green or yellow beans, trimmed and cut into 1-inch lengths
■ 2 cups peeled, sliced carrots
■ 3 ears corn, shucked, with kernels removed
■ Kosher salt and freshly ground black pepper
■ 3 teaspoons dried thyme
■ 3 teaspoons dried rosemary
■ 3 cups mashed potatoes

INSTRUCTIONS

1. Preheat the oven to 350ºF. Heat the vegetable oil in a large skillet over medium heat and add the meat and onion.

2. Cook until the meat browns and the onion is translucent, about 5 minutes. Add the garlic, green beans, carrots, and corn; cover and cook, stirring occasionally, until the vegetables are just tender, 5 to 7 minutes. Season with salt, pepper, and herbs, and stir.

3. Remove from the heat and scoop the mixture into a 6- by 9-inch buttered casserole dish. Cover with the mashed potatoes and bake until browned at the edges, about 30 minutes. Serve with brown gravy.
