Equipment

Ingredients

  • 4 cups chopped broccoli, stalk and florets cut into bite-sized pieces
  • 1 cup cooked quinoa, freshly made or store-bought frozen
  • 2 large eggs
  • 2 cups low fat shredded cheddar
  • 1 cup plain low fat Greek yogurt (I used Chobani)
  • 1 tablespoon minced garlic
  • teaspoon Dijon mustard
  • 1 teaspoon kosher salt
  • ½ teaspoon ground black pepper
  • 1 teaspoon curry powder
  • 1 10-inch tart shell optional

Instructions

  • Preheat the oven to 400˚F.
  • Steam the broccoli in a medium pot until it just begins to soften, about 5 minutes. Cool to room temperature.
  • Stir the remaining ingredients together in a large bowl until it looks like a smooth batter. Stir in the broccoli and quinoa. Pour it into a 9-inch X 13-inch casserole dish, if you prefer, a tart shell set into a 10-inch pie plate.
  • Bake on the middle rack for 30 minutes, or until set in the middle.

Notes

Prep Tips - Get It Done Quickly!

Broccoli
The 2 biggest reasons to take time to cut broccoli into neat, even-sized pieces is for appearance or even cooking. Because the broccoli is going into a casserole, this isn't so important. I purchase broccoli with the stalks.
To make quick work of prepping broccoli for this recipe, start with the stalk. Using a sharp chef's knife, slice off the bottom of the stalk, including parts that are split and browned. Slice the remaining stalk into 1/2" thick disks. Next slice the head of broccoli into quarters. Chop each quarter into bite sized pieces.
Obviously, an even faster way is to purchase a bag of frozen pre-cut broccoli. Follow the directions on the bag to cook.
Quinoa
Quinoa expands 2 - 3 times its volume when cooked.
I often have either a jar of quinoa I've already cooked up or have a package of frozen quinoa in the freezer. This allows me to add quinoa to salads, soups, and casseroles very easily for some additional protein. 
If you make your own, here's a post on the best way to cook up a pot of quinoa
Cheddar Cheese
To save time, you can purchase cheese pre-grated, but I think it’s well worth the extra 3 – 4 minutes to grate your own. Pre-grated cheese typically is coated with cellulose to keep it from sticking together, which dulls the flavor.
To grate it, use the largest holes on a flat or box grater.

Broccoli Cheddar Casserole Cooking Tips

  • If you prefer cooked brown rice in place of quinoa, you'll lose some protein, but have at it.
  • If you like a crunchy top, throw on some breadcrumbs sautéed in butter and lemon zest. 
  • If you want a little extra protein, add 2 tablespoons hemp seed hearts for 3 additional grams of protein.
  • The type of yogurt used will affect the consistency of the dish. I used Chobani Plain Low-Fat Greek Yogurt. When I tried it as a tart, as pictured, I was able to cut the resulting pie into wedges, reminiscent of a quiche. If you prefer a gooey casserole, use regular yogurt instead, and serve in an 8-inch x 8-inch casserole dish with a big spoon.
  • For a low-carb approach to this dish, prepare it without the crust.

Tips for the Omnivores at the Table

Add 1 cup chopped roasted chicken pieces to the casserole and bake. The baking time shouldn't be affected.
