This one pan meal couldn't be any easier. Simply combine packaged beef tips in gravy with a few common ingredients and you'll have the main dish on the table in no time.
Heat oven to 400°F. Spray 11 x 7-inch glass baking dish with nonstick cooking spray. Remove beef tips with gravy from package and place in prepared baking dish. Add sour cream, soy sauce, garlic and thyme; mix well. Stir in noodles, frozen vegetables and mushrooms. Cover with aluminum foil.
Bake in 400°F oven 35 minutes or until heated through. Top with french-fried onions. Bake, uncovered, 3 to 5 minutes or until onions are lightly browned.
