👩‍🍳 Step-by-Step Method

1. Caramelize the Onions

🧅 Melt butter in a pan over medium-low heat.
🧅 Add sliced onions and cook 15–20 mins, stirring occasionally, until golden brown and sweet. (Low & slow is key!)

2. Make the Roux

🌾 Sprinkle flour over onions and stir 1–2 mins to cook out raw taste.

3. Add Liquid & Simmer

🍷 Gradually whisk in stock to prevent lumps.
🍷 Add thyme & soy sauce (if using).
🍷 Simmer 5–10 mins until thickened. (Too thick? Add more stock!)

4. Season & Serve

🧂 Finish with salt & pepper to taste.
🍽️ Strain for extra smoothness (optional).

💡 Pro Tips for Perfect Gravy

🔸 Use a mix of onions (red + white) for complex flavor.
🔸 Deglaze with red wine for extra richness (add with stock).
🔸 Make ahead—gravy thickens when cooled; thin with warm water when reheating.
