These Mediterranean Style Tuna Stuffed Mushrooms are ideal for a light dinner on their own or a perfect accompaniment to any savored meal. This is a sponsored post written by me on behalf of Bella Portofino Tuna.
Today we’re preparing a batch of portobello mushrooms stuffed with a savory mix of tuna, parsley, and plenty of parmesan cheese, along with baby spinach and breadcrumbs. The addition of fresh lemon juice and zest brings in bright citrus notes that really help accentuate the savory mix. This mix combines to create a delicious Mediterranean-theme that would likely fit right in at your favorite bistro.
These mushrooms are a great light dinner choice on their own, but can also serve a side to things like steaks, hardy fish such as salmon or shark, or alongside a spicy red pasta sauce. As a nice bonus, this recipe is fairly simple to prepare.
Below, we’ll be going over the ingredients, and I’ll be recommending several key substitutions. I’ll also be covering a few delicious ways to get creative with this recipe.
Ingredient Checklist and Notes
- Portobello Mushrooms. I’m using portobellos for this recipe, but any mushroom sturdy enough for stuffing, such as cremini or shitake, would work just fine. However, I feel the ‘meaty’ texture and flavor of portobellos really helps this recipe shine.
- Tuna. For this recipe, I suggest using tuna in oil, and be sure to drain the tuna thoroughly before adding it to the recipe.
- Red Onion. Adds a bit of color, and cooks up sweet. That’s why I prefer Red Onion. Substitutes below.
- Lemon Juice. As in all cases, fresher is better, so opt for fresh lemon juice if you happen to have some lemons on hand. Bottled will work fine, but I do suggest fresh.
- Lemon Zest. For an extra ‘hint’ of lemon flavor, just be sure to rinse the lemon before zesting.
- Fresh baby Spinach. Baby spinach is simply the smallest variety of flat leaf spinach, and contains all of the same nutrient values as its larger cousins. While some frown on cooking baby spinach, the larger varieties, in my opinion, would simply overwhelm this recipe.
- Italian-Style Breadcrumbs. Extra flavor from the seasonings is always a plus, but if you only have plain on hand see below for how to make your own Italian-style breadcrumbs.
- Italian Parsley. Also called ‘flat leaf parsley,’ this is the parsley that goes ‘into’ a recipe, while ‘curly leaf parsley’ is used purely as garnish. Why is this? Because curly parsley tastes like…nothing, or – at most – like grass, and has almost no aroma.
- Garlic. For today’s recipe, be sure to chop the garlic up as fine as you can manage.
- Olive Oil. I’m using a fairly decent Extra Virgin Olive Oil for today’s recipe. Since you ‘will’ be tasting the oil in this particular recipe, I recommend using an olive oil that you wouldn’t mind using as a dipping oil.
- Parmesan Cheese. Use your grating cheese of choice, not a whole lot to say on this one.
Substitutes
- Fresh Lemon Juice. If you don’t have fresh lemons on hand, use an equal amount of bottled lemon juice.
- Parsley. An equal amount of cilantro and/or basil. For best results, make a mix that’s equal parts cilantro and basil. Conversely, dried parsley, dried, basil, or dried oregano can all stand in for the parsley.
- Make Your Own Italian Style Breadcrumbs. Making Italian-style breadcrumbs at home is incredibly simple. Just take half a cup of plain breadcrumbs, and then add in about a quarter teaspoon of black pepper, half a teaspoon salt, and a pinch each of red pepper flakes and dried oregano. Add in dried basil and dried parsley (about a quarter teaspoon of each), if you happen to have these on hand.
- Red Onion. Sweet onion would be the best substitute, but ‘any’ type of onion would work. Yes, these are used at a one-to-one ratio in place of the red onion.
Get Fancy
- Top it. Top the mushrooms with a copious layer of mozzarella before baking for extra cheesy goodness. Conversely, gouda, or a mix of mozzarella and gouda, would also work deliciously.
- Mix It. Mix in chunked feta, or chunked ricotta salada, into the stuffing for a delicious cheesy addition.
- Experiment with other fish. To really up today’s recipe, prep a nice piece of salmon in a marinade, cook it, preferably by baking in the oven, let it cool, and then crumble that up to stuff the mushrooms.
