Smoked Mackerel + Citrus Avocado Toast

This smoked mackerel + citrus avocado toast takes everything we love about avocado toast and gives it a serious upgrade — with Fishwife Slow Smoked Mackerel, segments of sweet and colorful citrus, creamy avocado, and flaky sea salt.

I nearly jumped for joy when the lovely folks at Fishwife (my FAVORITE tinned fish) sent me the most generous care package.

Needless to say I dove right in, and while I enjoyed revisiting my Mediterranean tuna salad and smoked salmon bowls I was equally excited to try some items that were new to me!

Here was the first, for those of you who missed it:

The other tin that caught my eye was this beauty – smoked mackerel with chili flakes:

And all I have to say is that you NEED to make this recipe!

Why You’ll Love This Smoked Mackerel Avocado Toast

• Protein-rich from the smoked mackerel
• Bright and fresh thanks to citrus segments (trust me on this!)
• Super satisfying from the creamy avocado + crunchy sourdough toast
• Perfect for brunch, post-workout or an elevated snack

Ingredients

• 1 ripe avocado
• Fresh lemon juice
• 2 slices sourdough, toasted till golden brown (I like to brush both sides with some good olive oil and toast in a skillet)
• 1 small grapefruit and/or orange, peeled and cut into segments
• 1 tin Fishwife Slow Smoked Mackerel with chili flakes, drained and flaked into bite-sized pieces
• Microgreens
• Flaky sea salt

How to Make Smoked Mackerel Avocado Toast

1. Halve the avocado, remove the pit, and scoop the flesh into a bowl.
2. Mash lightly, drizzle with lemon juice, and mash again.
3. Spread the avocado evenly over both slices of toasted sourdough.
4. Arrange the citrus segments over the avocado.
5. Scatter the smoked mackerel pieces around/between the citrus.
6. Top with microgreens and flaky sea salt.
7. Serve immediately!

Step-by-Step Assembly

Tips for the Best Avocado Toast

• Toast your bread well — those crisp edges!
• Don’t skip the lemon — it keeps the avocado from browning.
• Use citrus segments (not slices) — no membranes = better bite.
• Finish with flaky sea salt — is it even avocado toast without it?
• Want extra heat? A pinch of chili crisp or Aleppo pepper is perfect.

Substitutions + Variations

• Bread: Whole grain, country loaf, gluten-free, or ciabatta.
• Citrus: Blood orange, cara cara, Meyer lemon, or pomelo.
• Greens: Arugula, chopped herbs, or sprouts.
• Add-ons: Thinly sliced radish, pickled red onion, or capers.

Serving Ideas

• A chic brunch plate
• A nourishing lunch
• A post-workout snack
• Cut into wedges and serve as appetizers

FAQ: Smoked Mackerel Avocado Toast

Can I make this ahead?
You can prep the citrus and toast ahead, but assemble just before serving so the avocado stays fresh.

What kind of mackerel should I use?
Smoked mackerel packed in oil (like Fishwife) works perfectly. Just drain before flaking.

Can I use canned tuna instead?
Yes — it won’t be smoky, but it will still be delicious.

Is smoked mackerel safe to eat cold?
Yes, smoked mackerel is fully cooked and safe to eat straight from the tin.
