How to make vegetarian stuffed acorn squash

Step 1: Roast the acorn squash. Preheat the oven to 400F. Cut the acorn squash in half lengthwise and scoop out the seeds. Brush the insides with olive oil and salt. Place the squash halves on the baking sheet, with the cut sides up. Bake for 35-45 minutes, or until the squash is tender.

Step 2: Cook the quinoa. Rinse the quinoa in a fine mesh strainer under running water. Combine quinoa, orange juice, orange zest, and 1½ cups of water  in a medium saucepan. Cook on medium heat until it comes to a boil, then reduce heat to simmer and cook uncovered for 10-15 minutes, or until the liquid is absorbed. Turn off the heat and cover with a lid. Let stand for 5 minutes and then fluff the quinoa with a fork.

Step 3: Make the filling. Heat oil in a large pan over medium heat. Add mushrooms and thyme, and cook for 5 minutes without stirring. Flip the mushrooms over and cook for an additional 2-3 minutes. Add garlic, balsamic vinegar, and salt and cook for 1-2 minutes.

Step 4: Stuff the acorn squash. In the pan, stir in quinoa, cranberries, and goat cheese. Stuff the acorn squash halves evenly with the veggie-quinoa filling. Garnish with parsley. Serve immediately. 

Storage tips

You can store this stuffed acorn squash in the refrigerator for 3-4 days in an airtight container.

Expert tips

• Rinse the quinoa with a fine mesh strainer before cooking to get rid of the saponins. Saponins are naturally found in quinoa but have a bitter taste.
• The best quinoa to liquid ratio: The best quinoa to liquid ratio is 1:2 (1 part quinoa to 2 parts liquid). This allows the quinoa to cook properly without being too dry. The recipe calls for the juice of 1 orange, which is about ½ cup - that's why you only need to add 1½ cups of water.
• Don't cover the pot until after all of the liquid has absorbed and you've turned off the heat. Otherwise, it can get mushy and overcooked.
• How to zest an orange: To zest the orange, use a microplane or use a fine grater with small holes. Rinse and dry the orange first and only grate the orange outer part of the orange. The inner white parts taste bitter, so you'll want to avoid that.

Variations and substitutions

This quinoa stuffed acorn squash recipe is already vegetarian, gluten-free, and nut-free, but I've added a few variations that you can make to make it work for other dietary restrictions or any preferences you may have!

• Make it dairy-free and vegan: Omit the goat cheese. If you want the same creamy texture that goat cheese provides, you can add a vegan "cream cheese" alternative.
• Make it gluten-free: The ingredients in this recipe are inherently gluten-free, but if you're worried about cross-contact, check the label of the quinoa you're using to ensure it's labeled "certified gluten-free."
• Add nuts: Toasted sliced almonds, hazelnuts, pecans, or walnuts would taste wonderful in this recipe.

What to serve with quinoa stuffed acorn squash

This is a pretty hearty dish on its own, but if you want to make it even more filling, I recommend serving it with a salad, a side of veggies, or a source of protein like salmon. Try serving it alongside maple balsamic Brussels sprouts, a kale Brussels sprout salad, or paprika salmon.

Acorn Squash

• 4 medium acorn squash

• 1 cup quinoa

Instructions

 

• Preheat the oven to 400 degrees Fahrenheit and line a baking sheet with parchment paper. Cut the acorn squash in half lengthwise and scoop out the seeds. Brush the insides with 1 tablespoon olive oil and ⅛ teaspoon salt.

Cook on medium heat until it comes to a boil, then reduce heat to simmer. Cook uncovered for 10-15 minutes, or until the liquid is absorbed completely. Turn off the heat and cover the pot with a lid. Let stand for 5 minutes. Fluff quinoa with a fork.
• While the acorn squash and quinoa are cooking, heat oil in a medium-large pan over medium heat. Add mushrooms and thyme, and cook for 5 minutes without stirring. Flip mushrooms over and cook for an additional 2-3 minutes. Add garlic, balsamic vinegar, and salt, and cook for 1-2 minutes.
• Turn off the heat. Stir in quinoa, cranberries, and the goat cheese.
• Add the filling evenly into the acorn squash halves. Garnish with parsley. Serve immediately.
