Ingredients
- 2 medium acorn squash
- 8 oz brown mushrooms
- 1/2 cup quinoa
- 1 cup vegetable broth
- 2 tbsp fresh thyme
- 1 shallot
- 1 tbsp olive oil
- 2 tbsp toasted pumpkin seeds
- 1/2 tsp sea salt
- 1/4 tsp black pepper
Instructions
- Step 1: Preheat oven to 375°F (190°C). Cut 2 medium acorn squash in half lengthwise, remove seeds, and brush cut sides with 1 tbsp olive oil. Place cut-side down on a baking sheet and roast for 25 minutes until tender.
- Step 2: While squash roasts, finely chop 8 oz brown mushrooms and 1 shallot. Heat 1 tbsp olive oil in a skillet over medium heat, add mushrooms and shallot, and cook for 8 minutes until mushrooms release liquid and become golden.
- Step 3: Stir in 2 tbsp fresh thyme, 1/2 tsp sea salt, and 1/4 tsp black pepper. Add 1/2 cup rinsed quinoa and 1 cup vegetable broth, bring to a simmer, then cover and cook for 15 minutes until quinoa is fluffy and liquid absorbed.
- Step 4: Fluff cooked quinoa mixture with a fork, then spoon evenly into roasted squash halves. Top with 2 tbsp toasted pumpkin seeds.
- Step 5: Return filled squash to oven for 10 minutes to heat through. Serve immediately while warm.
