Here's another great recipe from Martha Stewart's Meatless Cookbook.
It's my favorite Vegetarian Cookbook.
If you have the opportunity to purchase it, I highly recommend it.
Butter, for ramekins
1 package (10 ounces) frozen broccoli florets
6 large eggs
1/2 cup half-and-half
1/8 teaspoon ground nutmeg
3/4 cup shredded cheddar cheese (3 ounces)
Preheat oven to 350 degrees. Butter four 8-ounce ramekins (or a 9-inch pie dish); set aside. Bring a medium pot of salted water to a boil. Add broccoli; cook 1 minute. Drain well; transfer to a cutting board, and blot dry with paper towels. Chop coarsely.
In a large bowl, whisk together eggs, half-and-half, 1/2 teaspoon salt, 1/4 teaspoon pepper, and nutmeg. Stir in broccoli and cheese.
Place ramekins on a rimmed baking sheet. Ladle broccoli mixture into ramekins, dividing evenly. Bake until golden brown, 35 to 40 minutes.
