Mexican Mason Jar Salad: Flavorful Meal Prep for On-the-Go

This Mexican Kilner jar salad is perfect for preparing ahead. When you’re ready to eat, turn the jar upside down so the dressing coats the ingredients. It’s colourful, healthy and works well as a main meal or a side salad.

I created this salad while taking part in a challenge to design a recipe that fits neatly inside a Kilner jar. Kilner jars have become a popular way to store and present food, from preserves and soups to drinks, desserts and salads.

I wanted a salad with Mexican flavours and bright, layered colours. The result is simple but very tasty, with distinct layers that make it both visually appealing and practical for make-ahead meals.

The key to a successful jar salad is layering. Put the dressing in first, then add the firmer, crunchier vegetables so they don’t go soggy. Tender leaves and herbs should sit at the top, away from the dressing, so they stay fresh and crisp until serving.

Ingredient notes for Mexican Kilner jar salad

To make this salad you will need:

• Lime – juice of one lime, freshly squeezed.
• Extra virgin olive oil – a good-quality oil adds flavour to the dressing.
• Hot sauce – use your favourite; I used Cholula for this version.
• Vegetables – I layer red pepper, cucumber, sweetcorn, red onion, avocado and tomato. Swap or adjust to use what you have.
• Red kidney beans – black beans or chickpeas also work well.
• Coriander (cilantro) – fresh herbs add brightness; keep them near the top so they remain fresh.
• Iceberg lettuce – a crisp, robust leaf that should sit at the top of the jar.

How to make a Kilner jar salad

Choose a jar large enough to hold all the ingredients without compressing them. I used a 1-litre jar, which generously serves two people or makes a side salad for four.

Always add the dressing first so it sits at the bottom. Next, add firmer vegetables that won’t go soggy when they contact the dressing. Softer ingredients, delicate herbs and lettuce belong at the top. Layering keeps everything crisp until you’re ready to serve.

To serve, either turn the jar upside down for a few minutes so the dressing runs through the layers, or shake the jar gently if the ingredients are robust enough. Tip the salad out onto a plate and enjoy.

Can you adapt this Mexican Kilner jar salad?

Yes. For more heat, add sliced chilli or pickled jalapeños in the layers. For a non-vegetarian option, add roasted or shredded chicken, leftover roast meat, or even grilled prawns. You can also swap beans, change the vegetables or vary the herbs to suit your taste and what’s in your fridge.

How long does a Kilner jar salad keep?

Stored in the fridge, this salad will keep for around three days. Prepare several jars in advance for quick packed lunches. For single servings, use smaller jars so each one is ready to grab and go.

What other salads could you put in a Kilner jar

You can use the same layering approach for many salads. Bean salads, grain salads, Mediterranean or Asian-style salads all work well in jars. Choose sturdy ingredients for the bottom and delicate leaves for the top for best results.
