I had quite a bit of leftover mashed potatoes from yesterday’s Christmas Dinner. I put this easy casserole together for lunch today. I used one pound sirloin ground beef, one finely diced small onion, 1/4 cup Worcestershire sauce, black pepper, one 8 ounce bag frozen vegetables (broccoli, cauliflower, carrots), 2 cloves minced garlic.
Saute the ground beef with onion, once cooked through add Worcestershire sauce, black pepper cook a few minutes on low heat with the vegetables, transfer to a baking dish. I used 3 cups leftover mashed potatoes and added them in a stand mixer bowl with minced garlic and whipped together. Transfer to the top of beef, spread in a single layer and bake @ 375 F for 10 minutes.
Easy and delicious!
