At some point during the next six weeks there is a distinct possibility that you and I will both be faced with the need for a covered dish. There are family celebrations, Friendsgivings, Thanksgiving, Hanukkah, Kwanzaa, Christmas and New years. So much cooking, eating and partying to do, not enough time!

So with all of that traveling and partying, I have a reoccurring problem, and maybe you do too. I want to bring a dish to share but it has to have three distinct qualities:

  1. The food has to hold well while traveling. In the food styling world, there is a term “the food died.” Which is when it took too long to get a photograph, and the food no longer looks good. It looks pretty for only so long and then it wilts or turns army fatigue brownish green. So when I am looking for a good dish to bring along with me, it can’t die in transit. It has to be just as perfect when I walk in the door to the festivities.
  2. The recipe has to be healthy. Because duh. That’s my first name. And selfishly I worry that there will only be super duper rich unhealthy choices that will land me on the couch with a belly ache. So I like to bring something that is healthy that I know I want to eat. And all the better if there isn’t any lactose lurking in it.
  3. It has to taste awesome or why bother bringing it because nobody will eat it if it doesn’t.

Cooks notes:

This cheddar leek cheese sauce is really delicious and creamy. It is on the thick side when you are done making it in the saucepan. But the cauliflower and broccoli let off extra liquid as they bake with the sauce so the sauce thins out perfectly by the time it is all done. I used Organic Valley Lactose Free milk and Cabot Alpine Cheddar (which is lactose free) to make mine since I am lactose intolerant. But you can use regular milk to make it, and whichever type of cheese you want. I recommend using a very sharp cheddar for the best flavor.

Why the flour? The flour in the sauce thickens it and makes it so that the cheese melts in smoothly. Without it (or an alternative starch) the cheese would become clumpy and would look curdled or would “break.” This way the sauce coats the vegetables much better with this thickener.

The step of cooking the vegetables and then shocking it in ice water is important so that it doesn’t keep cooking when it is mixed with the cheese sauce. Otherwize it would become more watery, sulfuric and the above mentioned army green color we’re trying to avoid.

broccoli and cauliflower casserole

This make-ahead casserole is a creamy delicious but healthy option for a covered dish for the holidays. The cauliflower and broccoli are coated in the delicious creamy leek cheddar sauce and topped with crunchy panko breadcrumb topping.

Ingredients

  • 1 medium head of cauliflower
  • 2 large broccoli crowns (1 pound)
  • 2 tablespoons plus 1 teaspoon extra-virgin olive oil, divided
  • 1 large leek, white and pale green part only, sliced and washed
  • ¾ teaspoon salt
  • 1/3 cup all-purpose flour
  • 2 cups fat-free milk (lactose-free if desired)
  • 6 ounces sharp lactose free cheddar, shredded (I used Cabot Alpine)
  • ¼ teaspoon ground white pepper
  • ¼ cup panko, preferably whole-wheat
  • 1 teaspoon paprika
  • ¼ teaspoon garlic powder

Instructions

  1. Bring a large pot of salted water to a boil. Set a large bowl of ice water to the side.
  2. Core cauliflower and cut into medium florets. Cut off broccoli stems and cut into florets. Blanch cauliflower 3 minutes in boiling water. Remove from the water with a slotted spoon or small strainer and transfer immediately to the ice bath to stop it from cooking. Repeat with the broccoli, cooking for 3 minutes, and shocking in the ice bath. Drain the vegetables very well. Reserve bowl for mixing in step 4.
  3. Prepare cheese sauce. Heat 2 tablespoons oil in a large saucepan over medium-high heat. Add leek and ¾ teaspoon salt and cook, stirring often until the leek is soft, 4 to 5 minutes. Sprinkle the flour over the leek and stir to coat. Add milk and bring to a simmer, over high heat, stirring constantly. Cook until bubbling and thickened, 1 to 2 minutes longer. Remove from heat and stir in cheese and pepper until the cheese is completely melted into the sauce.
  4. Preheat oven to 350 degrees F. Coat a 2 ½ quart baking dish with cooking spray. Stir panko, the remaining 1 teaspoon oil, paprika and garlic powder in a small dish until evenly moist. Mix the vegetables and cheese sauce together in the reserved bowl. Transfer to the prepared baking dish.
  5. Top with the panko mixture. Bake until the casserole is hot all the way through, the sauce is bubbling and the vegetables are tender, 28 to 35 minutes. Let cool 15 minutes before serving.

Notes

TO MAKE AHEAD: Prepare through step 4 (do not pre-heat oven in step 4.) Cover casserole in foil and refrigerate up to 24 hours in advance. Preheat oven, and bake casserole covered for 25 minutes. Remove foil and continue with topping with the breadcrumb mixture and baking as directed in step 5.
