Best Mustard Deals and Where to Buy in the UK: A Shopper’s Guide

Why mustard deserves a prime spot in your cupboard

Mustard is the little jar that thinks it’s a superstar — it can lift a sandwich, transform a dressing, or make a roast sing. Whether you reach for a sharp English mustard, a smooth Dijon, or a grainy wholegrain, mustard gives big flavour for a small price. If you love food that punches above its weight, exploring mustard options across UK shops is a tiny adventure that pays dividends at meal time.

Major UK supermarkets that carry great mustard ranges

Tesco

Tesco stocks everything from budget yellow mustards to premium Dijon and artisan jars, often in sizes from 7 oz to 12 oz. Look for own-brand variants that mimic well-known brands at a fraction of the cost, and check weekly offers — Tesco Clubcard deals sometimes make premium jars feel like a steal.

Sainsbury’s

Sainsbury’s tends to have a thoughtfully curated selection, including popular brands and seasonal varieties. If you like milder mustards for dressings or stronger ones for marinades, you’ll find 6 oz to 10 oz jars and squeeze bottles. Their mid-range lines often balance quality and value nicely.

Asda

Asda is a great place to hunt for multi-buy bargains on mustard. Look out for 8 oz and 10 oz multi-packs and own-brand options that compete with big brands on taste tests. Asda also stocks bigger tubs for home cooks who go through mustard quickly.

Morrisons

Morrisons carries both staple brands and more niche types like wholegrain or horseradish mustard. If you’re after a traditional Colman’s-style heat or a silky Dijon for sauces, their selection covers essentials in jars typically between 4 oz and 12 oz.

Waitrose

Waitrose specializes in premium and international options, making it ideal for shoppers after specialty mustards — think stone-ground, truffle-infused, or vine-aged varieties. Jars tend to be smaller, around 4 oz to 8 oz, but the emphasis is on artisanal quality and unique flavours.

Ocado

Ocado is an online haven for an extensive range of mustard brands, from household names to imported delicacies. Because Ocado aggregates many suppliers, you can find everything from tiny 3 oz boutique jars to larger 12 oz family sizes, delivered straight to your door if you shop online.

Aldi and Lidl

Don’t underestimate the discount supermarkets. Aldi and Lidl often rotate in premium-style mustards under their own labels, offering bold flavours at low prices. These jars are typically 8 oz and give excellent bang-for-buck, especially if you’re experimenting without wanting to overspend.

Specialist and artisan retailers to explore

Booths and regional food halls

Booths and similar regional food halls showcase local producers and artisan mustard makers. You’ll find unusual flavours, smaller 3 oz to 6 oz jars, and the chance to chat with staff who can recommend pairings — perfect if you enjoy discovering small-batch options.

Independent delis and farmers’ markets

Independent delis and farmers’ markets are gold mines for handcrafted mustards. Expect micro-batch runs with bold infusions like beer, cider, or smoked mustard. Buying local often means tasting before purchase and supporting producers within a few miles of your neighbourhood.

Online specialty shops

Specialty online retailers stock international and gourmet mustards that you might not find on supermarket shelves. Many sites offer 2 oz sample pots or curated bundles, so you can try three or four different styles without committing to a full-size jar.

Popular mustard brands and what to choose

Colman’s — the classic English heat

Colman’s is synonymous with sharp, English mustard. If you love a punchy condiment on a roast or hot sandwich, opt for a small 2 oz or 4 oz jar to keep it fresh. A little goes a long way here, so you won’t go through a jar too quickly.

Maille — smooth and sophisticated

Maille offers refined Dijon and flavoured mustards that are velvety and ideal for dressings and sauces. Their jars are often 7 oz or 9 oz and look great on a table when you’re entertaining. Maille suits people who prefer a milder, creamy profile.

Tracklements and UK artisan makers

Tracklements and other UK artisan brands focus on quality ingredients, producing tangy wholegrain and inventive blends. These makers often use 4 oz to 6 oz jars and appeal to foodies who want distinct textures and locally sourced ingredients.

How to choose the right mustard for cooking and snacking

Choosing the right mustard is like picking the right shoe for an outfit — context matters. For vinaigrettes and sauces, smooth Dijon or wholegrain with a bit of texture works best. For sandwiches that need a kick, reach for English or hot mustard. If you’re glazing meat, combine a grainy mustard with a little honey to get that sticky, caramelized finish. Think about jar size too: a 6 oz jar is ideal if you’re trying a new flavour, while a 12 oz tub suits families who use mustard as a daily staple.

Proportions and common measurements

When a recipe calls for mustard, it’s forgiving. Start with 1 tablespoon for every 4 servings and adjust to taste. If you’re making a glaze for a 3-pound roast, try 3 tablespoons of mustard mixed with 2 tablespoons of honey and 1 tablespoon of oil. These imperial-friendly measures keep things simple in most kitchens.

Tips to save money and find the best deals

Look for multi-buy offers and value ranges

Supermarkets often run multi-buy promotions — buy two 8 oz jars and save, or pick up a twin-pack for less per ounce. Value ranges from big chains can be excellent, delivering similar flavour profiles to premium brands at a lower price. If you use mustard regularly, buying a bulk 16 oz tub when it’s on promotion can be smart.

Use loyalty cards and seasonal promotions

Loyalty schemes at major supermarkets reward repeat buyers with points or discounts that can be used on groceries, including condiments. Keep an eye around national holidays or BBQ season when mustard and other condiments go on sale. Signing up for newsletters from the stores you frequent often nets you exclusive coupons.

Online vs in-store buying: which should you choose?

Advantages of shopping online

Shopping online gives you access to a wider range — including imports and specialty flavours — and lets you compare prices across multiple retailers at once. Sites often show size in ounces, making it easy to judge value per ounce. It’s perfect for planners who want to stock up without hopping between shops.

Why in-store hunting still matters

Buying in person lets you eyeball jar sizes, compare textures, and sometimes taste samples. You’ll often discover limited-edition jar colours or market-only batches. If you like the thrill of finding a hidden gem on a shelf, the in-store experience can’t be beat.

Storing mustard to keep it fresh and zesty

Mustard is surprisingly resilient, but proper storage keeps flavour sharp. Unopened jars can sit on a pantry shelf for months, but once open, store mustard in the refrigerator to prolong peak flavour. A 10 oz jar should stay lively for several months in the fridge, but if you notice a dull taste or separation, trust your senses. Also, avoid contaminating the jar with dirty spoons — a clean teaspoon keeps the contents fresher, longer.

Creative uses and quick recipes to try

Simple mustard vinaigrette

Whisk 2 tablespoons of Dijon mustard with 4 tablespoons of olive oil and 1 tablespoon of red wine vinegar. Season with salt and pepper, then drizzle over a bowl of mixed leaves. This basic dressing is a pantry hero — tangy, balanced, and ready in under 2 minutes.

Mustard-glazed chicken

Mix 3 tablespoons of grainy mustard with 2 tablespoons of honey, 1 tablespoon of oil, and a pinch of black pepper. Brush over a 3-pound chicken before roasting to get a golden, glossy glaze that contrasts sweet and tangy in every bite.

Elevate your sandwiches

Swap mayo for a thin swipe of mustard on both slices of bread to cut through rich fillings like roast beef or cheese. A half-teaspoon spread per slice is often enough to make flavours pop without overwhelming the main ingredients.

Sussing out speciality flavours and limited editions

Seasonal and limited-edition mustards can be delightful surprises — think whisky-infused autumn batches or citrus-forward summer blends. Supermarkets and delis sometimes stock these as small 3 oz or 4 oz jars, making them perfect for gifting or tasting. If you see an odd combination that intrigues you, buy it; small jars let you experiment without committing to a full-size jar.

Packaging and size considerations

Mustard comes in jars, squeeze bottles, and tubs. Jars often preserve texture better for grainy varieties, while squeeze bottles are convenient for hotdogs and quick sandwiches. For a household that uses mustard daily, a 12 oz or 16 oz jar is sensible; for occasional cooks, 4 oz to 8 oz is safer to prevent staling.

Which mustard pairs with what? Quick cheat-sheet

Pairings are simple: sharp English mustard with beef and game, Dijon with creamy sauces and fish, wholegrain with charcuterie and pork, and sweet mustard with honey-glazed recipes. Think of mustard as a sidekick — it enhances the hero ingredient without stealing the scene.

Where to find mustard bargains across the UK

To find consistent bargains, check weekly flyers, sign up for supermarket newsletters, and watch out for seasonal clearances. Discount chains rotate premium-style jars that often outperform their price. Also, local markets and farm shops may offer direct-from-producer deals that are wallet-friendly and support small businesses within a few miles of your community.

Conclusion

Exploring mustard across UK retailers is a tasty pastime that rewards curiosity. From budget jars at discount supermarkets to premium small-batch creations at delis and Waitrose-style stores, there’s a mustard for every meal and every budget. Use the tips above to find the best value per ounce, try sample sizes to discover new favourites, and store open jars in the fridge to maintain peak flavour. With a little tasting and a few smart buys, you’ll be the family’s mustard maestro in no time.
