Good to Know
Refrigerate in airtight container up to 3 days. Reheat gently on stovetop with splash of broth to restore sauce consistency.
Prepare onions, cube chicken, and mince garlic up to 1 day ahead. Do not caramelize onions in advance.
Garnish with fresh thyme leaves and additional shredded Gruyere cheese. Serve immediately while pasta is warm.

Do not skip the quick release step; natural release may result in overcooked pasta.
Avoid lifting the lid before 5 minutes are complete to prevent pressure loss and undercooked chicken.
Do not stir pasta after adding; settling ensures even pressure cooking.
