Essential Ingredient Guide

- Yellow onions: Slice thinly and cook low and slow to coax out natural sugars.
- Whole‑grain pasta: Provides a hearty bite and holds the sauce well.
- Nutritional yeast: Adds a subtle cheesy note without using animal products.
- Lemon juice: Brightens the sauce, balancing the sweet onion richness.
- Maple syrup: Just a drizzle enhances the caramelization; use sparingly.
