James Martin Bbq Sauce Recipe​​​​

This is a bold, smoky, James Martin-inspired BBQ sauce that hits all the right notes: tangy tomato, deep treacle richness, gentle heat, and a glossy, spoon-coating finish. It’s smooth enough to brush onto ribs, but thick enough to cling to burgers and wings without sliding off. The method is straightforward and beginner-friendly, with just a little oven roasting to build extra flavour. Total time is about 30 minutes, including cooling.

Ingredients

For the roasted aromatics

• 1 tbsp olive oil
• 1 small onion, finely chopped
• 2 garlic cloves, finely chopped (or grated)

For the sauce base

• 200g tomato ketchup
• 1 tbsp tomato purée
• 60ml cider vinegar
• 50g dark brown sugar
• 2 tbsp black treacle (or molasses)
• 2 tbsp Worcestershire sauce
• 1 tbsp Dijon mustard
• 120ml water, plus more to loosen if needed

For seasoning

• 1 tsp smoked paprika
• 1/2 tsp ground cumin
• 1/4 tsp chilli flakes (optional)
• Fine sea salt and black pepper, to taste

How to Make This BBQ Sauce

• Prepare the oven: Preheat the oven to 200°C or 180°C fan. Line a small baking tray with parchment (or lightly oil it) so the onions do not stick and burn.
• Roast the aromatics: Toss the chopped onion and garlic with the olive oil, spread out on the tray, then roast for 10 minutes until softened and just starting to colour. This step takes the raw edge off and adds a gentle sweetness.
• Mix the sauce: Scrape the roasted onion and garlic into a medium saucepan. Add the smoked paprika, cumin, and chilli flakes (if using) and stir over a low heat for 30 seconds to wake up the spices.
• Cook and thicken: Add the ketchup, tomato purée, cider vinegar, brown sugar, treacle, Worcestershire sauce, Dijon mustard, and water. Stir until the treacle dissolves, then bring to a very gentle simmer. Cook for 10 to 12 minutes, stirring often, until glossy and thick enough to lightly coat the back of a spoon.
• Blend (optional): If you want a perfectly smooth, brushable sauce, blend with a stick blender in the pan. For an extra-silky finish, pass it through a sieve, but this is optional.
• Cool: Take the pan off the heat and leave the sauce to cool for 20 minutes. It will thicken a little more as it cools.
• Assemble and use: Spoon into a clean jar or bottle. Use straight away as a dipping sauce, brush onto meat for the final 10 minutes of cooking, or thin with a splash of water for a quick marinade.

Tips

Why is my BBQ sauce too thin?

Keep it at a gentle simmer and give it a few extra minutes, stirring often so the sugars do not catch. Remember it thickens as it cools, so wait until it is fully cool before deciding it needs more reduction.

How do I stop it catching and tasting burnt?

Sugar and treacle scorch easily. Use a medium saucepan, keep the heat low, and stir frequently, especially around the edges of the pan where it thickens first.

How can I make it more smoky without liquid smoke?

Smoked paprika does a lot of the heavy lifting here. For an extra layer, add a pinch more smoked paprika at the end, or stir through 1 to 2 teaspoons of chipotle paste for smokiness and heat in one go.

What if it tastes too sharp or too sweet?

If it is too sharp, add a small pinch more brown sugar or a teaspoon of treacle, then simmer for 1 minute. If it is too sweet, add 1 to 2 teaspoons of cider vinegar and a pinch of salt to rebalance.

Serving Suggestions

• Brush onto ribs, chicken thighs, or wings for the final 10 minutes of cooking
• Serve as a dip with sweet potato wedges or onion rings
• Stir into pulled pork or shredded chicken
• Use on burgers, sausage baps, or bacon sandwiches
• Drizzle over roasted cauliflower or grilled corn

Storage

Room temperature

For food safety, keep the sauce at room temperature for up to 2 hours maximum, then refrigerate.

Refrigerator

Store in a clean, airtight jar or bottle in the fridge for up to 2 weeks. For best flavour, let it sit at room temperature for 10 minutes before serving so it loosens slightly.

Freezing

Freeze for up to 3 months in small portions (ice cube trays are handy), then transfer to a freezer bag. Defrost overnight in the fridge and stir well before using.

A rich, glossy BBQ sauce with ketchup, cider vinegar, treacle, Worcestershire sauce and smoked paprika. Perfect for brushing, dipping, and marinading.

Ingredients

• 1 tbsp olive oil

• 1 small onion, finely chopped

• 2 garlic cloves, finely chopped (or grated)

• 1 tsp smoked paprika

• 1/2 tsp ground cumin

• 1/4 tsp chilli flakes (optional)

• 200g tomato ketchup

• 1 tbsp tomato purée

• 60ml cider vinegar

• 50g dark brown sugar

• 2 tbsp black treacle (or molasses)

• 2 tbsp Worcestershire sauce

• 1 tbsp Dijon mustard

• 120ml water, plus more to loosen if needed

Directions

• Preheat the oven to 200°C (180°C fan).
• Toss the onion and garlic with olive oil, spread on a small tray, then roast for 10 minutes until softened and lightly golden.
• Tip the roasted onion and garlic into a saucepan. Add smoked paprika, cumin and chilli flakes and stir for 30 seconds.
• Add ketchup, tomato purée, cider vinegar, brown sugar, treacle, Worcestershire, mustard and water. Stir well.
• Simmer gently for 10–12 minutes, stirring often, until glossy and slightly thickened.
• Blend until smooth (optional), then cool completely before bottling.

Notes

• For a thicker glaze, simmer 2–5 minutes longer and cool fully.
• For a smoother, brush-on sauce, blend with a stick blender, then pass through a sieve if you want it ultra-silky.
• Keep it gentle: a hard boil can scorch the sugar and treacle.
