Instructions
Make the meat and vegetable filling
Heat olive oil in a Dutch oven over medium-high heat. Add the beef, onion, garlic, salt and pepper, and cook for about 5 minutes, or just until the beef has browned.
Add the broth, carrots, peas, corn, celery, oregano and thyme. Stir and cook on medium heat, uncovered, for 3 to 5 minutes, just until softened. Reduce heat to medium-low. In a small bowl, combine flour and water until well blended, then pour over the filling in the dutch oven. Stir together. Reduce heat to low, and cover.
Preheat oven to 350°F, and then make the mashed potato topping.
Mashed Potato Topping
Add potatoes to a large pot and cover with water. Bring to a boil, and boil until potatoes are fork tender, about 12-13 minutes. Drain potatoes and return to the pot.
Add the butter and mash potatoes until smooth. Add salt and pepper to taste.
Assemble and Bake
Remove the Dutch oven with the filling from the heat, and top with the mashed potatoes, smoothing into an even topping layer.
Bake, uncovered, at 350° F for about 30 minutes. To create a slightly browned, slightly crisp top, turn on the broiler at the end of the 30 minutes and broil for about 5 minutes. Watch the oven to make sure the top doesn't burn.
