Tips
Rinse quinoa thoroughly before cooking to remove the natural bitter coating called saponin.
Cook each vegetable separately to ensure proper texture and prevent overcrowding the pan.
Let the dish rest for 5 minutes after cooking to allow the cheese to melt completely and flavors to meld.
Good to Know
Refrigerate covered for up to 3 days. Reheat gently with splash of milk if needed.
Can prep vegetables up to 1 day ahead. Cook sausage earlier in day and refrigerate.
Serve immediately while cheese is melted. Garnish with extra fresh basil and red pepper flakes if desired.
Common Mistakes
Don't skip rinsing quinoa to avoid bitter taste.
Cook vegetables in batches to avoid steaming and maintain texture.
Stir milk gradually into quinoa to prevent lumps.

FAQ
Can I use regular quinoa instead of rinsed?
Yes, but rinse it yourself under cold water until water runs clear to remove the bitter saponin coating that can make the dish taste soapy.
What if I don't have a Dutch oven?
Use any large, heavy-bottomed pot with a tight-fitting lid. A deep skillet or wide saucepan works well as long as it holds at least 5 quarts.
How long does this keep in the refrigerator?
Store covered for up to 3 days. The quinoa may absorb more liquid as it sits, so add a splash of milk when reheating to restore creaminess.
