Leftover Roast Beef Casserole
Here is a delicious recipe for a leftover roast beef casserole. I’ve added plenty of veggies to make this a meal in a dish to help you save on dishes. And if you love cheese, like me, I’ve added a lot of that as well! But, you can always go less if you like.
Plus, it’s quick and easy to make and kid friendly! Better yet, it makes for great leftovers to take to school or work.
Beef Casserole Ingredients
Olive oil. Use whatever oil you normally use. Butter is another option, especially for the peas.
Onion. Use any white or yellow cooking onions.
Fresh rosemary. I prefer fresh when I have it, but you can also use dried. The fresh tastes better and also gives you a beautiful aroma in your kitchen. If using dried, go with about 1 tsp.
Carrots. Two large carrots is about all that you need.
Potatoes. Use whatever white or red potatoes you have in your pantry.
Frozen peas. Peas go so well with just about any dish, including meats, potatoes and carrots. I added two whole cups, but feel free to go less if you prefer.
Roast beef. Use any leftover roast that you have in your fridge.
Gravy. I like to use a homemade gravy made from the beef drippings, but other beef gravies will work as well.
Cheddar cheese. I LOVE cheese, and so do kids! I used at least 3 cups in this casserole, if not more. Feel free to use less if you prefer less.
