Stuffed Mushrooms with Tuna Recipe: Easy Spanish Tapa 2026

Stuffed mushrooms with tuna are one of those little Spanish tapas that disappear from the table before anything else. The caps roast until tender, while the filling stays juicy and savory with sweet onion, flaky tuna and a hit of oregano. It is comfort food that happens to be light, and it comes together in about 25 minutes.

This recipe is wonderfully simple: you make a quick sofrito of onion and chopped mushroom stems, fold in the tuna, then pile it into the caps and blanket everything with grated cheese. The oregano brings the aroma, though parsley or thyme work beautifully too. Serve them as a tapa spread or as a main with a fresh salad on the side.

Makes 2 servings

• 6 large mushrooms

How to Make Stuffed Mushrooms with Tuna Step by Step

1. Prep the mushrooms and preheat the oven

First, preheat the oven to 180 °C (350 °F). Clean the mushrooms and remove the stems, then cut the stems into small pieces.

2. Sauté the onion and stems

Heat 1 teaspoon of olive oil in a skillet and sauté 1 small chopped onion along with the chopped mushroom stems for 5–6 minutes, stirring the mixture occasionally.

3. Add the tuna and season

Turn off the heat and add 1 small can of drained tuna, then stir well. Season with salt and pepper to taste.

4. Fill the mushroom caps

Arrange the mushrooms on a baking tray, season them lightly with salt and fill them with the prepared tuna mixture.

5. Top with oregano and cheese

Sprinkle them with 1 teaspoon of dried oregano and finish with 2 tablespoons of grated cheese.

6. Bake the stuffed mushrooms

Bake the mushrooms for 10 minutes, until the cheese is golden.

7. Serve right away

Serve the stuffed mushrooms with tuna immediately so you can enjoy them freshly made.

Tips for the Best Stuffed Mushrooms with Tuna

Pick the right mushrooms

Look for large, firm mushrooms with closed caps so they hold the filling without collapsing. Wipe them clean with a damp cloth or paper towel instead of rinsing, since mushrooms soak up water and can turn soggy in the oven.

Make the filling your own

The oregano brings the aroma here, but parsley or thyme are also excellent options. Just keep the proportions the same so the tuna stays the star, and drain the canned tuna well so the mixture does not turn wet.

Serve them the Spanish way

These stuffed mushrooms shine on a tapas table or as a main course alongside a fresh salad. The gratinated cheese straight from the oven is what makes them irresistible, so bring them to the table as soon as they come out.
