Quinoa Stuffed Acorn Squash

This quinoa stuffed acorn squash recipe features a filling of leeks, walnuts and fresh herbs. It’s vegan, gluten free, and a total crowd pleaser!

Squashes are all over at the farmers markets this time of year in Indianapolis. I must admit that for years, the idea of winter squash never much intrigued me. It seemed hard and time consuming to prepare…and brought back faint childhood memories of being forced against my will to sample some each fall (just try it!). But today, stuffed acorn squash is one of Alex and my favorite fall treats! We love making acorn squash recipes, and this is one of our favorites: it’s got a fluffy quinoa stuffing flecked with leeks, walnuts, and fresh herbs.

How to roast acorn squash

Roasting acorn squash is incredibly simple and it’s easy to tell when it’s finished cooking. Here’s how to roast acorn squash for this recipe:

• Preheat to 425 degrees. A hot oven makes for the best roasting: it leaves the squash tender and almost caramelized.
• Slice the squash in half: Halve the squash using a very sharp knife and then scoop out the seeds. Find a groove to cut along on one side of the stem (but don’t cut the stem itself). Then cut around the end and through the other side. Use your hands to pop it apart. Tip: To make it easier, you can microwave the squash for 3 minutes before cutting.
• Drizzle with olive oil and sprinkle with kosher salt. This is all you need for great seasoning. Place the squash onto a parchment paper-lined baking tray (parchment paper is a must! It makes for easy cleanup) and sprinkle with salt and pepper.
• Roast until tender, about 35 to 40 minutes. The exact timing depends on the squash, so make sure to check with a fork to see when it is tender. The edges will turn slightly brown in the oven and the squash should smell slightly nutty as well.

How to cut leeks

Another skill in this recipe is cutting the leeks for the quinoa filling! If you’ve never cut a leek before, here is our tutorial. And make sure to watch this video to see it in action!

1. Chop off the dark green stems of the leeks and the bottom root.
2. Slice the leeks in half length-wise.
3. Place each leek half cut-side down on the cutting board, then slice it into thin slices, resulting in half-moon shapes. You will likely notice dirt in between each layer of the leeks,
4. Rinse the sliced leeks thoroughly in a colander, then shake them dry.
