Ingredients

26 oz frozen cut green beans, thawed. Thawing helps the beans heat through evenly without adding extra liquid to the casserole.
1 can (10.5 oz) condensed cheddar cheese soup. This provides the creamy, cheesy base that binds the dish.
1/2 cup milk. Adds a little looseness to the soup so the sauce is smooth and pourable.
1/4 cup dehydrated minced onion. Gives concentrated onion flavor without extra moisture.
2 tbsp Italian seasoning. A blend of herbs that brightens the cheese and green beans.
1/2 tsp salt. Enhances all the flavors.
1/2 tsp black pepper. Adds mild warmth and balance.
1 1/2 cups shredded cheddar cheese. Melts into the casserole for bold, tangy cheddar flavor.
1/3 cup shredded Parmesan cheese. Adds a savory, slightly nutty finish on top and throughout.

Step-by-Step Instructions

Preheat the oven to 350°F (175°C). Greasing the dish lightly helps prevent sticking.
In a large bowl, combine the thawed green beans, the condensed cheddar cheese soup, and the milk. Stir until the mixture is smooth and the beans are evenly coated.
Add the dehydrated minced onion, the Italian seasoning, the salt, and the black pepper. Mix well so the seasoning is distributed throughout.
Stir in the shredded cheddar cheese and the shredded Parmesan cheese. Fold gently until the cheeses are evenly incorporated.
Pour the mixture into a greased casserole dish, spreading it in an even layer so it bakes uniformly.
Bake for 30 to 35 minutes or until hot and bubbly. If the top browns too quickly, tent loosely with foil for the last 10 minutes.
Serve warm. Let the casserole sit 3 to 5 minutes after baking so the sauce thickens slightly before scooping.

Tips, Storage & Variations

Tip: Thaw the frozen green beans just enough to separate them, not fully cooked. This prevents a watery casserole.
Tip: Use freshly shredded cheese rather than pre-shredded for better melting and creaminess.
Storage: Cool the casserole completely, cover tightly, and refrigerate for up to 3 days.
Reheating: Reheat individual portions in the microwave or the whole casserole at 350°F until warmed through.
Freezing: You can freeze the baked casserole for up to 2 months. Wrap tightly in foil and place in an airtight container. Thaw overnight in the refrigerator before reheating.
Variations using existing ingredients only: Add an extra 1/4 cup Parmesan folded in before baking for a sharper finish. Stir a little more milk, about 1 to 2 tablespoons, if you prefer a saucier texture. Reduce the cheddar to 1 cup and increase Parmesan to 1/2 cup for a nuttier profile.
