Tasty Ingredients
- French fried onions: Layer these on at the very end for extra crisp. The fresher the brand, the better the crunch
- Shredded cheddar cheese: Spread for a gooey, rich finish–sharp or medium both do the trick
- Salt and pepper: Shake these in to make everything pop. Taste as you go so you don’t overdo it
- Garlic powder and onion powder: These make it extra tasty and smell great. Look for the spices with the freshest date
- Milk: Helps smooth out the creamy base and makes it easy to scoop. Whole milk gives a bit more richness
- Cream of mushroom soup: Holds everything together. Using a high-quality one gives you a deeper, better flavor
- Green beans: Use canned ones if you want things quick, or try fresh ones for some crunch and color
- Ground beef: This is the main star. Go with 80 or 85 percent lean for best juiciness and flavor
Simple Step-by-Step
- Dish It Up:
- Give the casserole a bit to cool before slicing in. That keeps those cheesy layers intact and easier to serve
- Add the Crispy Onions:
- Sprinkle French fried onions on the hot dish, then bake 5–10 minutes more so they get golden. This keeps the crunch right where you want it
- Pop in the Oven:
- Slide the pan in and bake for 25 minutes so the cheese bubbles and the edges get all hot. Everything should be piping
- Put It All Together:
- Spray a baking dish with nonstick or grease with butter, then add the filling. Finish with lots of grated cheddar all over the top so it browns evenly
- Mix the Filling:
- Move the browned beef to a bowl. Toss in the mushroom soup, drained beans, milk, the spices, salt, and pepper. Stir until it’s all smooth and mixed. It’ll look creamy and thick
- Sizzle the Beef:
- Cook beef in a big frying pan on medium. Bust up the meat and stir so it browns evenly. When it’s cooked through and there’s no pink, pour off the grease so it doesn’t get soggy
- Get the Oven Hot:
- Crank the oven to 350°F and let it come all the way up to temp before you bake. That way the whole thing cooks nice and even

How to Store Leftovers
Keep any extras in a sealed container in the fridge up to three days. Warm single portions in the microwave or reheat bigger helpings in the oven, covered, so it stays soft. If you’re not feeding a crowd, save the crispy onions till serving so they don’t go soggy in the fridge
Swaps and Switch-Ups
Try ground turkey or chicken instead of beef for a lighter bite. Got fresh green beans? Use those if you like. Gluten-free eaters—pick gluten-free cream soup and onions. Toss in mushrooms or bell peppers for added veggies

How to Serve It
Great next to a fresh salad with a tangy vinaigrette or some cooked broccoli for color. Toasted bread is awesome for soaking up the sauce. If little ones are eating, you can throw some tater tots over the top for a fun twist before baking
