Method
Make the casserole
- Heat the oven to 400°F.
- Coat a 9x13-inch baking dish with the cooking spray.
- Stir the soup, 1 cup milk, and black pepper together in the dish.
- Fold in the green beans and spread evenly.
- Bake for 10 minutes.
Make the biscuit topping
- Whisk the flour, baking powder, and salt together in a medium bowl.
- Cut in the cold butter until the mixture has pea-size pieces.
- Stir in the cheddar and 3/4 cup milk just until a thick, slightly shaggy dough forms.
Assemble and bake
- Drop the biscuit dough in 8 mounds over the hot casserole, leaving a little space between them.
- Bake for 20 to 25 minutes, until the biscuits are deeply golden and a biscuit split in the center has no wet dough.
Make the garlic butter
- Melt the butter.
- Stir in the garlic powder and parsley.
Finish and serve
- Brush the garlic butter over the biscuits.
- Scatter the French fried onions over the casserole.
- Rest for 5 minutes before serving.
Notes
For the best biscuit texture, cut the cold butter into the flour mixture until the pieces are pea-size. Refrigerate leftovers in an airtight container for up to 4 days; freezing is not recommended because the biscuits can lose their texture. For a gluten-free variation, use a gluten-free flour blend and gluten-free condensed cream of mushroom soup.
