Tips
Blend the sauce completely smooth for silky mouthfeel; lumpy flour-milk mixtures won't fully incorporate into pasta
Add milk gradually while stirring to prevent lumps forming in roux; rushing creates grainy sauce
Nutritional yeast provides B-vitamins and savory depth; don't skip or substitute without losing signature flavor
Good to Know
Refrigerate in airtight container up to 4 days. Sauce may thicken when cold; rewarm gently with splash of milk to loosen. Do not freeze (soy milk-based sauce separates upon thawing).
Prepare sauce completely and refrigerate separately from pasta up to 2 days. Cook pasta fresh and combine just before serving to maintain texture.
Serve immediately in bowls while sauce is hot and glossy. Pair with crusty bread and simple green salad to balance richness.
Common Mistakes
Don't skip blending the sauce; unblended sauce with visible flour specks tastes grainy
Don't add milk too fast; dumping it in creates lumps that won't smooth out
Don't cook onions longer than directed; brown onions add bitterness that overwhelms delicate vegan cheese flavor

FAQ
Can I make this gluten-free?
Yes. Use gluten-free pasta and substitute 1/4 cup cornstarch or gluten-free flour for all-purpose flour. Cornstarch thickens faster, so reduce slightly to avoid overly thick sauce. Check vegan cheese packaging for gluten.
What if my sauce breaks or looks separated?
Strain through fine mesh into fresh pot, discard solids. Gently reheat over low heat while whisking constantly. Add milk 1 tablespoon at a time until smooth. This typically happens if heat was too high during cheese addition.
Can I freeze this for later?
Not recommended. Soy milk-based sauces separate and curdle when frozen. Freeze cooked pasta separately up to 3 months; make fresh sauce when reheating. Better option: refrigerate complete dish 4 days and reheat gently.
