Instructions

1. Caramelize Onions: Heat Dutch oven over medium, melt butter and olive oil. Add sliced onions with salt and pepper, stirring occasionally until deep golden-brown and richly developed, approximately 30-35 minutes.
2. Build Flavor Base: Introduce minced garlic, red pepper flakes, soy sauce, and Worcestershire sauce to caramelized onions, sautéing briefly to intensify aromatics.
3. Create Liquid Foundation: Combine water and half evaporated milk, whisk cornstarch with remaining milk. Raise heat, bringing mixture to boil while incorporating beef bouillon and selected herbs.
4. Cook Pasta: Submerge pasta into bubbling liquid, reduce heat to gentle simmer. Cook uncovered for 11-14 minutes, stirring frequently to prevent sticking and ensure even cooking.
5. Finalize Sauce: Remove from heat, gradually fold in Gruyere cheese, allowing complete melting between additions. Incorporate Parmesan cheese until sauce reaches smooth, creamy consistency.
6. Season and Garnish: Adjust seasoning with salt and pepper, potentially thinning sauce with additional water or milk. Optional: Sprinkle fresh parsley on top for vibrant presentation.

Notes

• Caramelize Carefully: Low and slow heat transforms onions into sweet, golden perfection; rushing risks burning and bitter flavors.
• Cheese Melting Technique: Add Gruyere and Parmesan gradually, stirring constantly to ensure smooth, even melting without clumping.
• Liquid Balance Matters: Monitor pasta cooking liquid closely; too little causes sticking, too much creates watery sauce.
• Flavor Layering Strategy: Introduce seasonings sequentially – soy sauce, Worcestershire, red pepper flakes – to build complex, deep taste profiles.
