FAQ

  • Can I use fresh tomatoes instead of canned diced tomatoes?Certainly, fresh tomatoes can be used instead. Take approximately 4 medium-sized tomatoes, chop them up, and you might want to add a little salt and pepper to bring out their flavor a bit more.
  • Is there a substitute for Manchego cheese?If you cannot find Manchego, a similar semi-firm cheese that works well is Monterey Jack. Aged cheddar is another good alternative if you want a taste and texture that work comparably.
  • Can I use tuna in water instead of tuna in olive oil?Certainly, you can use water-packed tuna. Still, you might consider adding a tablespoon of olive oil for flavor, since water-packed tuna is less rich than oil-packed tuna, which contributes a nice dimension to this dish.
  • How can I make this dish gluten-free?Ensure that all other ingredients, including canned tuna and cheese, are certified gluten-free. If breadcrumbs are used, ensure that they are gluten-free or omit them.
  • Can I prepare this dish ahead of time?You can indeed make the vegetable and tuna mixture a day in advance. Just put it in the fridge, and when you’re ready to bake, add the breadcrumbs and cheese just before it goes in the oven.
  • What side dishes go well with this bake?This dish goes nicely with the following:

    – a simple green salad
    – roasted potatoes
    – a crusty baguette

    All are great at soaking up the dish’s flavorful juices.

  • How do I store leftovers?Keep any uneaten portions stored in a sealed container in the refrigerator for no more than three days. To reheat, use an oven set to 350°F (175°C) until the food is hot throughout. For a quick option, use the microwave.

Spanish Tuna Vegetable Bake Recipe Substitutions and Variations

1 large onion, chopped – Substitute with 2 shallots, chopped.

Pro Tips

1. Sauté with Wine: For added depth of flavor, deglaze the pan with a splash of white wine after sautéing the onion and garlic, allowing it to reduce slightly before adding the bell peppers.

2. Zest Boost: Include a bit of lemon zest in the breadcrumb and parsley topping. This will add a refreshing citrus aroma and enhance the overall flavor profile.

3. Roast the Veggies: To intensify the taste and bring out the natural sweetness, roast the diced bell peppers and zucchini in the oven before combining them with the other ingredients in the skillet.

4. Cheese Options: If Manchego is unavailable, you can substitute with another aged cheese like Pecorino Romano or a mild cheddar for a slightly different flavor while maintaining a rich, creamy texture.

5. Breadcrumb Crunch: For an extra crispy topping, toast the breadcrumbs in a dry skillet for a few minutes before mixing them with parsley, ensuring an appealing golden crust after baking.
