• 1 tbsp Dijon mustard

How to Make Easy Tuna Stuffed Avocados: A Step-by-Step Guide

Creating this delicious dish could not be simpler. We have outlined the entire process in four easy-to-follow steps for you.

1. Prepare the Avocado Boats: First, carefully cut your avocados in half from top to bottom and remove the stone. With a spoon, gently scoop out about one tablespoon of avocado flesh from the centre of each half. This creates a more generous well for your filling, forming the perfect Avocado boat! Place the scooped-out flesh into a medium bowl.
2. Mash the Avocado Flesh: Squeeze the fresh lemon juice over the avocado flesh in the bowl. Using a fork, gently mash it until you have a slightly chunky texture. The lemon juice not only provides a lovely, bright flavour but also helps stop the avocado from turning brown.
3. Create the Tuna Filling: Into the same bowl, add the well-drained tuna, mayonnaise, finely diced red onion, celery, Dijon mustard, and chopped fresh dill. Stir all the ingredients together until they are just combined. This is the perfect moment to have a little taste and season with salt and pepper as needed.
4. Stuff and Serve: Now, spoon your delicious tuna mixture into the hollowed-out avocado halves, filling them generously. Garnish with a little more fresh dill, a light dusting of paprika for a pop of colour, or some chopped spring onions for a fresh bite. Serve straight away and enjoy your masterpiece!

Tips and Tricks for the Perfect Tuna Avocado Boat

Although this recipe is beautifully simple, we have a few handy tips that can help you take it from great to truly exceptional. Here is what we have discovered from making this dish countless times.

Choosing the Right Avocado

The avocado is undoubtedly the hero of this dish, so selecting a good one is key. You’re looking for an avocado that gives slightly when you apply firm, gentle pressure with your palm. It should feel a little soft but not at all mushy. If it feels very hard, it needs more time to ripen. Conversely, if it feels too soft or has indentations, it is likely overripe and may be bruised inside.

Preventing Browning

The one minor drawback to avocados is their tendency to oxidise and go brown when exposed to air. The lemon juice in our recipe is your first line of defence. If you plan to make the tuna filling ahead of time, we suggest storing it in an airtight container with cling film pressed directly against the mixture’s surface. For the very best results, however, we always recommend stuffing the avocados just before you intend to serve them.

Getting the Best Tuna

For a clean, fresh flavour that allows the other ingredients to sing, we suggest using high-quality tuna packed in spring water. Draining it very well is crucial to prevent the filling from becoming watery. If you prefer a richer taste, you can use tuna packed in olive oil, but be sure to drain it just as thoroughly.

Fun Variations on the Healthy Tuna Stuffed Avocado

One of the greatest attributes of this recipe is its sheer adaptability. It’s a brilliant Healthy lunch idea that you can enjoy time and again without it ever feeling repetitive. Here are some of our favourite ways to change things up:

• For a Spicy Kick: Add a bit of heat by mixing in a finely diced red chilli, a pinch of crushed red pepper flakes, or a few drops of your go-to hot sauce.
• A Taste of the Mediterranean: Infuse your filling with a Mediterranean flavour by adding a tablespoon of chopped Kalamata olives, a tablespoon of crumbled feta cheese, and some finely chopped sun-dried tomatoes.
• For Added Crunch: To introduce more texture, try mixing in some finely diced bell peppers, cucumber, or even a sprinkling of toasted sunflower seeds.
• From the Herb Garden: Don’t feel limited to dill! Experiment with a combination of fresh parsley, chives, and a touch of coriander for a more complex, herbaceous flavour.
• The No-Mayo Option: If mayonnaise isn’t for you, a creamy texture can still be achieved by mashing a little extra avocado into the tuna mix or by substituting it with full-fat Greek yoghurt.

What to Serve with Your Low Carb Tuna Avocados

These stuffed avocados are wonderfully satisfying as a complete meal on their own, but they also pair beautifully with a variety of side dishes. For a light and well-rounded lunch, we adore serving them with a simple green salad. A Classic House Salad with Red Wine Vinaigrette provides a lovely contrast to the creamy avocado. If you fancy something with a bit more crunch, why not try them alongside our Crunchy Asian Chicken Salad with Peanut Dressing?

For those not following a strict low-carb diet, these tuna boats are also fantastic served with some whole-grain crackers, a slice of toasted sourdough, or a handful of sweet potato crisps.

A Closer Look at the Health Benefits

This is more than just a delicious meal; it’s a treasure trove of nutrients. The combination of avocado and tuna provides a remarkable range of health benefits, making this dish a truly intelligent choice for your well-being.

Avocados are celebrated for their high concentration of monounsaturated fats, which are fantastic for heart health. As noted by the British Heart Foundation, swapping saturated fats for unsaturated ones can help to manage cholesterol levels. They are also a superb source of dietary fibre, which supports healthy digestion and helps you feel full for longer.

Tuna offers an excellent source of lean protein, which is vital for building and repairing our bodies’ tissues, and it’s also packed with omega-3 fatty acids. This makes our Low carb tuna recipe not only tasty but also incredibly beneficial for both body and mind. It’s the kind of meal that makes you feel good from the inside out.
