This delicious and quick side dish of creamy broccoli cauliflower parmesan is ready in just 20 minutes. A recipe that's easy enough for weeknight meals and nice enough for potlucks or holidays. Make it with both vegetables or only one - your choice!
Steam broccoli and/or cauliflower until just crisp tender, 6-7 minutes.
Meanwhile, make the white sauce: melt the butter in a saucepan over medium heat, add the onion and garlic, cooking until the onion is tender.
Measure the flour, pepper, dry mustard, and salt into a small bowl and whisk together. Sprinkle the flour mixture over the cooking onions, stirring together.
Gradually pour in the milk and heat until the mixture bubbles, stirring constantly.
Remove from heat and whisk in 1/3 cup of the grated cheese, stirring until melted.
Start broiler preheating.
Arrange steamed broccoli and cauliflower in a heatproof shallow dish or small platter and pour the sauce over the top. Sprinkle with the remaining cheese and some paprika.
Broil the dish about 3 inches from the heat about 3 minutes, until cheese is melted and bubbly.
Serve immediately.
Notes
Make Ahead Option:For taking to potlucks, you can steam the vegetables and make the sauce beforehand. Then right before serving, warm the vegetables and sauce, place in a bowl or platter, and pour sauce over vegetables. Sprinkle paprika and then broil.
