One year at Thanksgiving my sister brought a delicious vegetable dish called broccoli parmesan that we all loved. Since then it’s become a holiday tradition and has shown up at many holidays as well as potlucks.
Besides tasting so good, the other thing this recipe has going for it is that it’s also quick and easy – it’s ready in about 20 minutes, start to finish. Needless to say, it’s become one of my favorite vegetable dishes any time of the year.
This recipe was adapted from one of my most-used cookbooks, the Junior League of Eugene’s Savor the Flavor of Oregon cookbook and I often make it with both broccoli and cauliflower, as well just broccoli or just cauliflower.
In fact, in these photos I used a Romanesco cauliflower (sometimes called broccoli, but it’s really more of a cauliflower). It’s just as delicious and nice that the recipe is adaptable to what you have in the fridge.
This is like a lighter version of those cheese-soaked broccoli dishes, with the wonderful taste of Parmesan (though Romano or Asiago work well, too).
Broccoli and Cauliflower Parmesan
Ingredients & Equipment
For this recipe you’ll need:
- broccoli or cauliflower, or a combo – even Romanesco, pictured here
- dry mustard
- parmesan or asiago, or romano cheese
Equipment you’ll need includes:
- 3 quart saucepan
- steamer insert/basket
- measuring cups and spoons
- sharp knife
- heatproof shallow dish (about 1 1/2 quarts)
- fine grater
This recipe is so simple!
The first step is to steam the broccoli or cauliflower until tender. Of course you can use both or one – totally up to you.
While the vegetables are steaming, make a simple white sauce with added onion and garlic.
Melt the butter in a saucepan, add chopped onion here and garlic and cook until soft. Then whisk in a mixture of flour, salt, black pepper, and dry mustard.
Add milk gradually, and then heat until mixture bubbles, stirring constantly. Turn off the burner and add part of the grated Parmesan until melted.
Arrange vegetables in a shallow dish and pour the sauce over the top, sprinkling with remaining cheese.
Put the dish under the broiler (about 3-inches from the heat) for 3 minutes, or until cheese is melted and bubbly.
I don’t think you will view the humble broccoli or cauliflower the same way after tasting this.
The flavor of parmesan is so good with these vegetables. I even sprinkle steamed broccoli with just grated Parmesan now if I don’t have the time to make the sauce. Yummm.
