Tennessee Onion & Cheese Casserole
This casserole can be used as a side dish for any pot luck and is typically made with butter, sweet onions and cheese. It’s important to use sweet onions to balance the sharpness of the cheese. As the onions cook they create a sauce with the butter and cheese. This would make a great topping for burgers with your cheese and onions all in one!
- Cooking spray
3 large sweet onions such as Vidalia (about 2½ pounds), peeled and sliced crosswise into ¼-inch thick slices and separated into rings
4 tablespoons Cabot Unsalted Butter, melted
- 3 tablespoons fresh chopped herbs, such as parsley, thyme, chives or oregano, plus more for serving
- 1 large clove garlic, grated
½ teaspoon dry mustard
¼ teaspoon salt
¼ teaspoon ground fresh pepper
PREHEAT oven to 350°F. Coat a 9-by-13-inch baking dish with cooking spray.
COMBINE onions, butter, herbs, garlic, mustard, salt and pepper in a large bowl until onions are evenly coated. Transfer the onions to the prepared baking dish and arrange in an even layer. Sprinkle with 4 ounces (1 cup) shredded cheddar and 4 ounces (1 cup) shredded Gouda.
COAT a piece of aluminum foil with cooking spray and place the sprayed side on top of the casserole (to avoid cheese sticking to the top).
BAKE the casserole until the onions are soft and sides are bubbly, about 40 minutes. Remove the foil and sprinkle the remaining 1 ounce (¼ cup) cheddar and 1 ounce (¼ cup) Gouda evenly on the top. Continue baking, uncovered, until the top is golden and the cheese has melted, about 30 minutes. Serve sprinkled with additional herbs, if desired.
