Then, stir in the cooked quinoa, bell pepper, broccolini, and cheese.

Next, spoon the mixture into the prepared baking dish, taking care not to mess around the edges too much. (That is if you care about the looks of your casserole.)

What To Serve it with

Tips and Variations

  • Inspect and rinse broccolini well, pat dry before chopping.
  • Before cooking quinoa,* rinse to remove the compounds called saponins, plant-derived organic chemicals, that can give the quinoa a bitter taste.
  • Try toasting quinoa before cooking if you haven’t yet jumped on the quinoa bandwagon; it gives this grain a whole new dimension.
  • Variations, Add-ins, and toppings for quinoa broccoli recipes:
    • Diced protein like chicken, sausage, or leftover turkey
    • Feta cheese or herbed goat cheese
    • Shredded carrots and mushroom
    • Blanched and quartered Brussels Sprouts
    • Diced tomatoes and red onion (Add-in or topping)
    • Top with sour cream and pickled jalapenos

Common Questions

Can I substitute broccoli for broccolini?

Absolutely. If you have everything to make this yummy, cheesy quinoa casserole except broccolini, and no time to run to the store, here are other options that will provide that nice earthy grassy flavor: Chinese broccoli, cauliflower, zucchini, asparagus, spinach, or kale

Can I use frozen broccoli in a quinoa casserole instead of fresh?

Yes, you can use frozen broccoli, but it should be thoroughly thawed and drained. Fortunately, most frozen broccoli is bagged now instead of frozen into those neat little 4 x 6” boxes of old, which made for a good solid green block of ice. However, either type can be placed in a colander with a plate under it and allowed to thaw. Once the broccoli has thawed and drained, pat dry with paper towels or a clean, lint-free cotton cloth.

Can I add other veggies?

Yes. Feel free to add any other veggies you have on hand.
