Cooking the beef filling first in a large skillet and then in the oven ensures that the meat and vegetables are tender and flavorful. Finishing the casserole in the oven browns the breadstick-dough topping. For a fun presentation kids will love, make individual servings in 4-ounce ramekins. You can also freeze single servings for later.
1 tablespoon olive oil, divided
1 pound ground sirloin
2 cups chopped zucchini
1 cup chopped onion
1 cup chopped carrot
1 teaspoon dried basil
1/2 teaspoon dried thyme
1 (8-ounce) package presliced mushrooms
3 garlic cloves, minced
1/4 cup tomato paste
1 1/2 teaspoons Worcestershire sauce
1/2 teaspoon freshly ground black pepper
1 (14-ounce) can fat-free, less-sodium beef broth
2 tablespoons cornstarch
2 tablespoons water
1 (11-ounce) can refrigerated soft breadstick dough
How to Make It
Preheat oven to 400°.
Heat 1 1/2 teaspoons oil in a large nonstick skillet over medium-high heat. Add beef; cook 3 minutes or until browned, stirring to crumble. Drain. Wipe drippings from pan with a paper towel. Heat remaining 1 1/2 teaspoons oil in pan. Add zucchini and next 6 ingredients; sauté 7 minutes or until vegetables are tender. Return beef to pan. Stir in tomato paste and next 3 ingredients. Bring to a boil; cook 3 minutes. Combine cornstarch and 2 tablespoons water in a small bowl; stir with a whisk. Add cornstarch mixture to pan; cook 1 minute, stirring constantly.
Spoon beef mixture into an 11 x 7inch baking dish coated with cooking spray. Separate breadstick dough into strips. Arrange strips in a lattice fashion over beef mixture. Bake at 400° for 12 minutes or until browned.
For baby: Serve spoonfuls of potpie in a small bowl.
