This one started as a “clear out the cupboard” moment—tin of beans, half a celery stick, a wrinkled tomato I nearly binned. But to be honest, I wasn’t expecting much. Mixed bean salads can be bland, right? Toothsome, yes—but often a bit… meh.
What surprised me was how alive this one tasted once I got the dressing right. My first go was too sharp (too much vinegar, not enough oil), but with a tweak and a good chill in the fridge, it turned into a punchy, herby little side dish that genuinely perks up a plate. Let me show you how I fixed that—and what made the biggest difference.
The Secret Behind This Bake (well, salad)
This isn’t just beans in a bowl with vinaigrette. Here’s what makes it pop:
- Dijon mustard gives the dressing proper backbone. It’s not just for bite—it helps emulsify the oil and vinegar so the whole salad gets coated instead of just soggy.
- Tarragon and parsley might sound a bit French-bistro-fancy, but they’re doing real work here. Tarragon brings an unexpected aniseed lift that freshens everything up.
- Resting time matters. I let mine sit for 30–60 minutes in the fridge and it mellowed beautifully—like the dressing had time to get to know everyone.
INGREDIENTS + WHY THEY MATTER
- Mixed beans (400g tin) – Protein, texture, and bulk. I use a no-salt version and rinse them well to lose that tinned flavour.
- Spring onions (2) – Milder than raw onion but still punchy. I once used red onion instead—too harsh.
- Celery (2 sticks) – Adds crunch and freshness. Don’t skip it. I did once, and it lost all its bite.
- Tomato (1 large) – Juicy and sweet. De-seeding helps keep the salad from going watery.
- Olive oil (3 tbsp) – Go for a mild extra virgin. Cheap stuff will make the whole salad taste bitter.
- White wine vinegar (1 tbsp) – Brings brightness. I tried lemon juice once—not the same zip.
- Sugar (1 tsp) – Softens the vinegar’s edge. I accidentally left it out once—too sharp.
- Dijon mustard (2 tsp) – For heat and emulsification. English mustard is too fiery.
- Tarragon and parsley (1 tbsp each) – One’s grassy, one’s licoricey. Together, they lift the whole bowl.
Making It Yours (Without Ruining It)
- No Dijon: Wholegrain mustard works, but don’t go with yellow mustard. Too sweet.
- No tarragon: I’ve swapped in basil in summer—different, but still bright.
- Want it vegan: Already is.
- Low FODMAP version: Skip the spring onion and use chopped chives instead.
- Add-ins that actually work: Diced red pepper, a handful of sweetcorn, or chopped hard-boiled egg. I’ve tried all three.
MISTAKES I’VE MADE (AND HOW TO AVOID THEM)
What Went Wrong | Why It Happens | How to Fix It |
---|---|---|
Dressing too sharp | Too much vinegar, no balance | Add sugar and taste as you go |
Beans tasted bland | Didn’t season enough | Be generous with salt and pepper |
Watery salad | Used juicy tomato and skipped de-seeding | Always de-seed the tomato before dicing |
HOW TO MAKE MARY BERRY’S MIXED BEAN SALAD
- Prep your veg: Chop spring onions, slice celery thinly, and dice the tomato (don’t forget to de-seed it).
- Rinse the beans: Tip your mixed beans into a sieve and give them a really good rinse under cold water. Drain well—soggy beans dilute the dressing.
- Make the dressing: In a small jug or bowl, whisk together the olive oil, vinegar, sugar, Dijon, tarragon, and parsley. Keep whisking until the dressing looks slightly thickened—no oily separation.
- Combine it all: In a big bowl, gently mix the beans, veg, and dressing. Season with salt and a few good cracks of black pepper.
- Chill: Pop it in the fridge for at least 30 minutes before serving. I promise it tastes better cold.

TIPS FROM MY KITCHEN
- I always make the dressing first—gives the flavours time to mingle.
- A silicone spatula helps gently toss the beans without mashing them.
- My fridge is quite cold, so I take the salad out 10 minutes before serving to take the chill off.
- If making for lunchboxes, keep the dressing separate and add just before eating—it stays fresher.
STORAGE + SERVING
- Keeps well for 3 days in the fridge in a sealed container.
- Do not freeze—the veg turns mushy.
- Serve with grilled chicken, salmon, or a wedge of frittata. It’s great with crusty bread for a no-fuss lunch.
FAQs – Real Query Answers
Q: Can I use dried beans instead of tinned?
A: Yep, but cook them properly and cool completely first. You’ll need about 250g cooked beans total.
Q: What are the best beans to use?
A: I like the tinned mix with cannellini, chickpeas, and kidney beans. If DIY-ing, aim for variety—one creamy, one firm, one nutty.
Q: Can I make this a day ahead?
A: Absolutely. In fact, it gets better overnight. Just give it a toss before serving.
Q: Is there a way to make it spicy?
A: Add a pinch of chilli flakes or a dash of Tabasco to the dressing. I’ve done both—fab with grilled fish.
Q: Why did my salad taste flat?
A: Probably under-seasoned. Beans need more salt than you think. A squeeze of lemon can also lift it.
