🧅 What Is Onion Gravy?

Onion gravy is made by gently cooking onions until soft, then thickening them with flour and stock to create a smooth, savoury sauce. The onions add natural sweetness, while the stock provides depth and richness.

It can be made with beef, chicken, or vegetable stock depending on preference.

🧂 Ingredients for Easy Onion Gravy

You will need:

• 1–2 onions, thinly sliced
• Butter or oil
• Plain flour
• Stock (beef, chicken, or vegetable)
• Salt and black pepper

Optional additions include Worcestershire sauce, soy sauce, or a splash of wine for extra depth.

🍳 How to Make Easy Onion Gravy

1️⃣ Cook the Onions

Heat butter or oil in a pan over medium heat. Add the sliced onions and cook gently for 8–10 minutes until soft and lightly golden. Stir regularly.

2️⃣ Add the Flour

Sprinkle over the flour and stir well, cooking for 1–2 minutes to remove the raw flour taste.

3️⃣ Add the Stock

Gradually pour in the stock while stirring to avoid lumps. Bring to a gentle simmer.

4️⃣ Simmer

Allow the gravy to simmer for 5–10 minutes, stirring occasionally, until thickened.

5️⃣ Season

Season with salt and black pepper to taste. Add optional extras if using.

🔥 Tips for the Best Onion Gravy

• Cook onions slowly for better sweetness
• Don’t rush the flour stage
• Add stock gradually for a smooth texture
• Simmer gently to develop flavour
• Taste before adding extra salt

If the gravy is too thick, add a splash of water or stock. If too thin, simmer a little longer.

🌿 Easy Variations

You can adapt onion gravy easily:

• Vegetarian onion gravy – use vegetable stock
• Rich onion gravy – add a knob of butter at the end
• Dark onion gravy – add a splash of Worcestershire sauce
• Smooth gravy – blend briefly for a finer texture

These small changes make the gravy suit different meals.

🍽️ What to Serve with Onion Gravy

Onion gravy is perfect with:

• Sausages and mash
• Roast dinners
• Pies and pasties
• Meatballs
• Yorkshire puddings

It’s a versatile sauce that works across many dishes.

🌿 Final Thoughts

Easy onion gravy proves that simple ingredients can deliver big flavour. With softly cooked onions, good stock, and gentle simmering, you can make a rich, comforting gravy in minutes.

Once you’ve made it from scratch, shop-bought gravy rarely compares.
