Comfort food at its best: Think creamy sauce, meaty richness, and tender green beans.

How To Make It

Prep time: ~10 minutes
Bake time: ~25-30 minutes
Total time: around 40 minutes
Servings: 4

Ingredients

1 lb ground beef
1 (15 oz) can green beans, drained
1 (10.5 oz) can cream of mushroom soup

Optional extras (to taste): shredded cheese, crispy fried onions, or breadcrumbs for topping.

Directions

Preheat your oven to 350°F (175°C).
In a skillet over medium heat, cook the ground beef until fully browned. Break it up as it cooks. Drain off any excess fat.
In a mixing bowl, combine the cooked beef, drained green beans, and the cream of mushroom soup. Stir until everything is well coated.
Transfer the mixture into a greased casserole dish (an 8×8-inch works well).
If you like, top with shredded cheese or fried onions for extra flavor and texture.
Bake for 25-30 minutes, until the casserole is bubbling and the top is lightly golden.
Let it rest a few minutes before serving so the flavors settle and it’s easier to slice.

Serving Suggestions

This casserole is hearty enough on its own, but you can round out the meal with:

Garlic bread or warm dinner rolls
A crisp green salad with something tangy (vinaigrette works great)
Mashed potatoes or fluffy rice to soak up the sauce
Maybe a simple fruit dessert afterward

Tips & Variations

Add diced onions or garlic to the beef for more depth.
Swap canned green beans with fresh or frozen; blanch fresh beans first if you use them.
Try different “cream” soups—cream of chicken, celery, or cheddar can give a new twist.
Dress up the top: cheese, fried onions, or even crackers/breadcrumbs for crunch.
You can assemble ahead of time, refrigerate, then bake when ready.

Storing & Reheating

Leftovers: Cool completely, store in an airtight container in the fridge. Keeps for up to 4 days.
Reheat: Use the microwave or pop it into an oven-safe dish at around 350°F until heated through (15-20 minutes in the oven works well).
Freezing: Freeze in a tightly covered, freezer-safe dish for up to 2 months. Thaw in fridge overnight, then bake until hot.
