Ingredients

1 ½ pounds ground beef
2 cups mixed onions and bell peppers I use frozen
29 ounces green beans 2-14.5 ounce cans drained
10 ¾ oz condensed cream of celery soup
2 cups shredded Cheddar cheese 8 ounces divided use
1 cup milk
salt and pepper to taste
12 ounces frozen onion rings

Instructions

Preheat the oven to 425.
Brown ground beef in a 12-inch *cast iron skillet.
Add the mixed onions and peppers and cook until they are softened.
Remove from heat.
Mix in drained green beans; set aside.
Whisk cream of celery soup, 1 ½ cups of the cheese, and the milk together in a medium mixing bowl.
Pour over the green bean mixture in the skillet and stir gently to combine.
Sprinkle the remaining cheese over the top.
Arrange the onion rings over the top of the cheese.
Press down lightly.
Bake for 30 minutes or until the onion rings are crispy brown and the casserole is heated through. It should read 165F on an instant read thermometer when stuck in the center.
Remove from the oven and serve.

Notes

*NOTE- if you don't use a cast iron skillet be sure that the skillet is oven-proof. If not, or if in doubt, just transfer the green bean mixture to a casserole dish.

Storage:

Ground beef casseroles are best stored in the refrigerator for up to four days. Freeze leftovers for up to three months.

Tips:

You may want to drain off extra beef grease if you're using an 80/20 or 85/15 blend. Any leaner than that and you're fine to leave the fat.

I recommend using regular milk (skim, 1%, or 2%) or evaporated milk for this recipe. However, you can use unsweetened almond or oat milk if it's all you have. (Make sure it doesn't have any vanilla or flavoring, though.)

If you don't have an oven-safe skillet or fry pan, transfer the cheesy ground beef and green bean mixture to a casserole dish to bake.

If the onion rings aren't quite crisp enough for your liking after the casserole is done baking, finish it under the broiler for a minute or two.
