Roasted Squash Rings Stuffed with Quinoa Mushroom Salad


By Priscilla Martel

Quinoa is the Mickey Rooney of grains, small in stature but big on texture and taste. Slices of squash are the perfect portion control for this recipe, nutty Roasted Squash Rings Stuffed with Quinoa Mushroom Salad. You can even include it on your Thanksgiving buffet. Cook the squash rings and make the quinoa salad a couple of days ahead.

Foodies adore quinoa, much to the dismay of native Peruvians who have depended on this nutritional powerhouse for centuries because it is a good source of protein. Barely larger than poppy seeds, the pearls of quinoa burst during cooking. You want to see little white rings throughout the cooked quinoa to know that each individual grain is hydrated and tender.

Don’t be deceived by quinoa’s diminutive size because this grain speaks for itself.  You’ll enjoy seasoning it aggressively. In the fall, I opt for something traditional that mimics poultry stuffing and the flavors that go with turkey; carrots, celery, mushrooms and cranberry. Don’t let the “diced fine” in this recipe intimidate you.  Yes, it is chef speak for something that sounds fussy, but it isn’t there to test your knife skills.  Small uniform pieces of the vegetables match the scale of the quinoa making it pleasing to chew. If you don’t mind washing an appliance, pulverize the carrots and celery in a food processor.

Garnish the stuffed squash rings with their seeds toasted, as long as you resist eating them before serving the dish.  (This happens more often than I care to confess; toasted squash seeds are one among many weaknesses.)

Embellishments? Drizzle the quinoa-filled-rings with balsamic vinegar. If you have or can make balsamic glaze, even better. (Heat a cup of Balsamic vinegar in a small sauce pan over medium heat until reduced to a few tablespoons. That’s balsamic glaze.)


Yield: 10 – 12 Servings

For the Roasted Squash and Quinoa:

2 – 3 Tablespoons olive oil, more if needed

1 ½ –2 pounds Delicata squash

Salt and pepper to taste

1 cup white quinoa

2 cups vegetable or chicken stock

1 small carrot, diced fine

2 tablespoons celery, diced fine

¼ cup shallot, diced fine, about ½ large shallot

1/3 cup dried cranberries

1/4 cup mushrooms, diced fine

Finely grated zest and juice of 1 lemon

Fresh flat leaf parsley as needed

For the Toasted Squash Seeds:

Squash seeds reserved from the squash

2 Tablespoons olive oil

Salt and pepper


  • Preheat the oven to 400° Brush a parchment- or foil-lined baking sheet with 1 Tablespoon of the olive oil.
  • Wash and dry the squash. Cut it into ¾-inch thick slices. Remove the seeds. Save them to toast and use as a garnish.
  • Place the squash slices on the baking sheet. Season lightly with salt and pepper. Drizzle with a little more olive oil. Bake until the squash is tender and nicely browned, for about 30 – 35 minutes. Set aside in a warm place. (Or cool then refrigerate. You can prepare the squash up to two days ahead.)
  • Rinse the quinoa in a fine strainer under cold running water. Pick out any dark seeds and debris. Combine the quinoa with the stock in a small saucepan. Bring to a boil. Cover, then reduce heat and simmer until the quinoa is tender and popped and all of the stock has been absorbed, for approximately 10 – 15 minutes. Spoon it into a bowl.
  • Sauté the celery and carrots in the remaining 1 Tablespoon of olive oil until almost tender, for about 6 – 8 minutes. Add the mushrooms and a little more olive oil, if needed, and continue to cook, over medium heat until the mushrooms are tender, 5 or 6 more minutes.
  • Add the cooked vegetables and cranberries to the hot cooked quinoa. Add the lemon juice and zest. Adjust the seasonings as needed.
  • To make the Toasted Squash Seeds garnish, rinse the reserved squash seeds in a strainer under cold water. Dry them on a layer of thick paper towels. Use the paper towels to rub off any fiber that clings to the seeds. Spread the seeds out onto a baking sheet lined with parchment or foil. Drizzle them with the olive oil. Sprinkle with salt. Roast the seeds at 350°F until they are lightly brown and crunchy, for approximately 6 – 8 minutes. You’ll know they are almost done when you hear them popping.
  • To serve, reheat the squash rings if necessary. Place one squash ring on each serving plate. Spoon a generous mound of the quinoa salad into the center of each squash ring. Garnish with a few sprigs of fresh parsley. Scatter some of the toasted seeds, if using, on top of each serving.  And drizzle with balsamic vinegar glaze if you want to gild the lily.
  • Or place the squash rings onto an oven-to-table serving platter. Fill each ring with some of the quinoa salad and garnish. Keep the squash rings warm in a low oven. To serve from a buffet, slide a flat metal spatula to lift each filled ring onto serving plates.
