Ingredients

• 2 small acorn squash, about 1.5 pounds or 680g each
• 1 cup or 240 ml water
• 1/2 cup or 92g uncooked quinoa, rinsed and drained
• 1 teaspoon ground cumin
• 1/2 teaspoon salt
• 1 ear fresh sweet corn, kernels removed, or 1/2 cup or 75g frozen corn, thawed
• 1 cup or 150g chopped red bell pepper
• 2 green onions, chopped
• 2 medium fresh jalapeño peppers, seeded and minced
• 1 tablespoon or 15 ml olive oil
• 1 15-ounce or 425g can black beans, rinsed and drained

Instructions

1. Preheat your oven to 350°F or 175°C. Carefully cut each acorn squash in half lengthwise. Use a spoon to scoop out and discard the seeds and stringy membranes. Place the squash halves, cut-side down, in a large baking pan and bake for 45 to 50 minutes, or until just tender when pierced with a fork.
2. While the squash bakes, prepare the quinoa. In a medium saucepan, combine the water, rinsed quinoa, cumin, and salt. Bring the mixture to a boil, then reduce the heat to low, cover, and simmer for about 15 minutes until all the liquid has been absorbed. Fluff with a fork.
3. In a large skillet, heat the olive oil over medium heat. Add the corn, red bell pepper, green onions, and minced jalapeño. Sauté for about 5 minutes, stirring occasionally, until the vegetables are crisp-tender.
4. Add the cooked vegetable mixture and the rinsed black beans to the saucepan with the cooked quinoa. Stir everything together until well combined. Carefully flip the baked squash halves so they are cut-side up. Generously spoon the quinoa filling into each squash half, mounding it on top.
5. Return the stuffed squash to the oven and bake, uncovered, for another 15 minutes, or until the filling is heated through. Serve immediately and enjoy!

Pro Tips

• Wear gloves when handling jalapeños to avoid skin irritation from their volatile oils. If you don’t have gloves, wash your hands thoroughly with soap and warm water immediately after handling.
• To save time, cook the quinoa and sauté the vegetables while the squash is doing its initial 45-minute bake.
• For extra flavor, toast the dry quinoa in the saucepan for a minute or two over medium heat before adding the water. This brings out a wonderful nutty aroma.
• Customize your filling! Feel free to add a cup of chopped mushrooms or spinach along with the other vegetables, or top with toasted pumpkin seeds before the final bake for a delightful crunch.

FAQ

Q: How can I add more plant-based protein to this stuffed acorn squash
A: This dish already provides a solid 13g of protein per serving from the quinoa and black beans. To boost it further, you could add a handful of toasted pumpkin seeds or chopped walnuts on top before the final bake. Another great option is to stir in a cup of cooked lentils or chickpeas with the quinoa filling.

Q: Can I use a different grain instead of quinoa
A: Absolutely! While quinoa is a great gluten-free, high-protein choice, this recipe is very flexible. You can easily substitute it with an equal amount of cooked brown rice, farro (note: not gluten-free), millet, or even a wild rice blend for a different texture and flavor profile.

Q: How do I store and reheat leftover quinoa-stuffed acorn squash
A: Leftovers are delicious! Store the stuffed squash in an airtight container in the refrigerator for up to 4 days. To reheat, place it in a baking dish, cover with foil, and warm in a 350°F (175°C) oven for about 20-25 minutes, or until heated through. You can also microwave individual portions for a quicker option.

Q: Is this recipe suitable for a low-spice diet
A: Yes, it’s very easy to adjust the spice level. The heat comes from the jalapeño peppers. For a milder version, you can omit the jalapeños entirely or replace them with half a chopped green bell pepper for a similar texture without the heat. The cumin adds savory warmth without being spicy.
