Can I prepare the stuffed acorn squash ahead of time, and how should I reheat it without drying out the squash?
Yes—you can roast the squash, make the quinoa filling, stuff the halves, and then refrigerate the assembled dish (tightly covered) for up to 24 hours. To reheat without drying, place the stuffed squash on a baking sheet, splash a tablespoon of broth or water into each cavity, cover loosely with foil, and warm in a 350 °F (175 °C) oven for about 20 minutes, uncovering for the last 5 minutes to refresh the top.
Can I substitute quinoa with another grain (e.g., brown rice or farro), and how should I adjust the liquid ratio and cooking time?
Absolutely—cook the alternate grain separately, then fold it into the squash just as you would the quinoa. For brown rice, use 2 cups broth : 1 cup rice and simmer 40–45 min until tender; for pearled farro, use about 3 cups broth : 1 cup farro and simmer 20–25 min (40 min for whole farro, or soak it overnight to shorten the time). Once the grain is cooked and fluffy/drained, proceed with the recipe unchanged.
What can I use instead of pecans for a nut-free version?
For nut-free crunch, replace the pecans with toasted pumpkin seeds (pepitas) or sunflower kernels; they brown in a minute or two and give a similar buttery snap. Crispy roasted chickpeas or shelled edamame are other allergy-friendly options, or you can simply omit the nuts—the filling stays tasty and cohesive without them.
