Can I use a different pasta shape?
Yes. Anelli works well for trapping sauce, but ditalini, small shells, or even fettuccine work. Avoid very long shapes.
How long does caramelizing the onions take?
Plan 25–35 minutes over medium to medium-low heat, stirring occasionally. Don't rush this step; deep golden-brown onions are essential to flavor.
Can I make this ahead?
Cook the pasta slightly underdone, cool, then refrigerate. Reheat gently in a skillet with a splash of broth to restore creaminess.
What if I don't have Boursin cheese?
Substitute cream cheese (4 oz) mixed with fresh herbs (thyme, parsley) and a pinch of garlic powder.
Can I skip the white wine?
Yes. Use an extra 1/2 cup beef broth instead, or 1/4 cup apple cider vinegar for acidity.
