Weekend Recipe: Spinach Squares
Spinach squares, like this recipe from Cook's Country, are warm, cheesy, finger-food hors d’oeuvres with a simple dump-and-stir method, but many versions are greasy and pale, with lackluster flavor.
Swapping butter for vegetable oil spray and reducing the cheese slightly cut the grease. We boosted flavor by using strong, nutty Gruyère instead of cheddar, exchanging relatively bland milk for more savory chicken broth, and topping the squares with a layer of grated Parmesan (which also helps with browning). Upping the oven temperature and cooking on the upper-middle rack finished the job, creating a deeply browned top.

You can thaw the spinach in the microwave or overnight in the refrigerator. Cooled Spinach Squares can be refrigerated for up to 24 hours and reheated, covered in foil, in a 375-degree oven.

1 teaspoon baking powder
3/4 teaspoon salt
1/2 teaspoon pepper
1/4 teaspoon cayenne
1 cup low-sodium chicken broth

1 1/4 pounds frozen chopped spinach, thawed and squeezed dry
12 ounces Gruyère cheese, shredded (3 cups)
1 onion, chopped fine
2 garlic cloves, minced
1 ounce Parmesan cheese, grated (1/2 cup)
