The Mixture - Green Bean, Mashed Potato, Ground Beef Casserole

Total Time
Prep 25 mins
Cook 30 mins

My mom used to call this "the Mixture" and it was always a favorite around our house growing up.

Ingredients Nutrition


  1. Peel the potatoes and cut into chunks. Start them boiling.
  2. Meanwhile, start green beans boiling.
  3. Meanwhile, brown ground beef.
  4. Slice onions and spray casserole dish with non-stick coating.
  5. Place the browned ground beef in the bottom of the casserole dish. Cover with half of the cheese (tearing cheese slices into chunks if using) and half of the sliced onions.
  6. Add green beans next, and repeat cheese & onion layers.
  7. Drain potatoes, add milk and butter in your preferred amounts and mash. I use about 2 tablespoons butter & add milk until the consitancy is right.
  8. Spread mashed potatoes over top of casserole.
  9. Sprinkle with additional cheese and breadcrumbs followed by paprika if desired, otherwise just with paprika.
  10. Bake for about 20-30 minutes in a 400 oven until top of mashed potatoes is golden and cheese is well melted. May be prepared in advance, refridgerated and baked later.
  11. Hints: if this is too bland, some suggestions to spice it up: try adding garlic, worcestershire sauce and other spices when browning beef. Add paprika and garlic powder to the potatoes while mixing. Use jalapeno cheese.

This was an excellent and tasty casserole! I thought I had enough green beans, but I didn't. So I added some frozen carrots and peas. In the filling, I used sliced white onion, chopped green onion (My SO can't handle a lot of white onion), mozzarella and cheddar cheeses. For the topping, I made my own breadcrumbs (using wheat bread) and parmesan was the cheese. Thank you so much for the great recipe. I will make this again and again! :)

This meal was absolutely delicious! My family loved it!!! My husband who is a chef thought that this meal could use a little spiciness so he added a little hot sauce on the side and loved it. It was perfect for the kids who cannot eat spicy food. I follow the instructions as stated but I had to make a few changes that made it more flavorful. 1). I added Panko instead of breadcrumbs.
2. I seasoned the meat very well because the mash potatoes and green beans are already blend.
3. I added 2-3 tbsp of Velveeta cheese to give it the creamy consistency that I was looking for.
4. I used french style greens beans instead of whole (this makes a huge difference). The presentation is beautiful and the Panko give it that little crunch that you need. Ummm So Good!

This was great! I was looking for a way to use our leftover potatoes and didn't have much time, but this took very little time and the whole family loved it (including the 11 mo. old and 3 year old twins :) I used ground turkey instead of ground beef, and frozen peas and broccoli instead of green beans, and added plenty of garlic and worcestershire to the beef. I especially liked that this recipe didn't call for canned soup that has MSG in it. Will definitely make this again.
