This Spanish Baked Rice is Valencia’s BEST-KEPT Secret
This Spanish baked rice, known as arroz al horno con atún y tomatoes, is Valencia’s best-kept secret. It’s filled with flavors, easy to make, and done in a little over 40 minutes. Serve it next to a garden salad and a bottle of Spanish wine for a taste of the Mediterranean.

To make this recipe, I used Spanish short-grain rice, which is the one that is used to make paella. Very similar to Arborio rice. Of course, you can use any rice you like here. Just make sure to check the package instructions; that way you get your liquid-to-rice ratios right on the money.

For the liquid, I used homemade vegetable broth. You can also use chicken broth, fish broth, or even water if you prefer. Just make sure to season accordingly if using water. As all these broths contain salt.

TIPS & TRICKS to Make this Recipe: Make sure to use an oven-proof pan here. As the rice is finished in the oven. The size of the pan I used was 12 inches (30 cm). This rice will hold for up to 2 to 3 days in the fridge and freeze for up to 3 months.
