All About Spanish Rice: Arroz Caldoso, Paella & More

Here’s our foolproof guide to ordering paella and other scrumptious Spanish rice dishes.

Types of Spanish rice dishes

With the exception of the eastern region of Valencia (the birthplace of paella), what the rest of the world calls “paella” goes by many different names here in Spain. In fact, outside of Valencia, the dishes that are not called paella are often even more delicious!

Paella

Purists will tell you that the only dish that should ever be called paella is the traditional recipe for paella valenciana. But the roots of this now iconic Spanish rice dish are not what you might imagine!

True Valencian paella has no seafood and is only about two centimeters (less than an inch) deep in the pan. It originated as a hearty lunch for workers in the fields far from the coast.

The traditional recipe calls for rabbit, snails, and large green beans and is cooked over an open fire in a thin, round pan known as a paella. That’s right: the name for Spain’s most famous rice dish actually comes from the pan it is cooked in!

To avoid confusion, many Spaniards now refer to the pan as a paellera while using the word “paella” to refer to the food.

Today, you can find many delicious variations of paella, including the famous seafood version, paella mixta (a sort of surf-and-turf), as well as vegetarian paella.

Arroz al caldero

The thing about paella is that the rice soaks up all the cooking liquid, so the end result isn’t very moist. But if you’re craving a Spanish rice dish so juicy that it’s almost creamy, look for arroz al caldero.

This rice dish is prepared in a deep, black, cauldron-like pan and hails from Murcia, the region just south of Valencia along the Mediterranean coast. And where paella is all about the crisp crust on the bottom of the pan, arroz al caldero puts its money on intense flavors and luxuriously creamy textures.

The secret to a spectacular arroz al caldero is all in the broth, which often contains up to 15 different types of fish, and the smoky ñora peppers that are native to Murcia.

Arroz con bogavante (or anything else!)

Outside of Valencia, most menus will refer to rice dishes as just that: arroz. Most are still cooked using the exact same paella pan, but because the ingredients and the region are different, it’s not called a paella. Instead, it’s “rice with…” whichever main ingredient they’ve chosen to add. 

Perhaps the most prestigious ingredient is bogavante, or lobster. A well-made arroz con bogavante is a flavor-packed thing of dreams. Other popular ingredients are scallops, shrimp, chicken, and fish.

Arroz caldoso

This style of rice will have you debating whether to grab a fork or a spoon! 

Arroz caldoso literally means “brothy rice.” This style of Spanish rice dish is popular throughout the Iberian Peninsula (Portugal included!) and has hundreds of variations, from seafood to vegetables to chicken.

Arroz Negro

With its inky black color, this style of rice lives up to its name. 

Arroz negro, or black rice, gets its jet black color from squid ink. It usually contains calamari and other seafood hidden in the inky goodness. And don’t forget to ask for bright white alioli sauce, a garlicky mayonnaise, to go with it.

Words to know

When it comes to ordering Spanish rice—or making it at home—there are a few words you’ll want to know. Here are few terms that might come up that you probably didn’t learn in your Spanish class at school.

Socarrat

Perhaps the most important word when talking about paella! Socarrat is the crispy, almost burnt layer along the bottom of the paella pan. Only the best paella chefs know how to create socarrat without burning the rice, making it a surefire sign of a great paella.

Paellera

The large, shallow, round pan used to make paella and many other Spanish rice dishes.

Azafrán

Saffron. As the key ingredient in paella, saffron famously gives the dish its characteristic yellow color.

Fun fact: while it is commonly used in Spanish cooking, saffron is one of the most expensive spices in the world. Many Spaniards substitute it for a yellow food coloring to cut down on the cost of making paella.

Caldero

A deep, cauldron-like pan used to make the creamy Murcian-style of rice known as arroz al caldero.

Garrofón

A unique style of large, flat, green beans used in a traditional paella valenciana. You can find these unique beans almost exclusively along Spain’s easternmost provinces in the region known as Levante. If you’re not in eastern Spain, butter beans are an acceptable substitute.

Ñora pepper

The secret to spectacular arroz al caldero. These dried, round peppers are an essential part of the broth and bring a richness and deepness of flavor to the rice. Most chefs use about three ñora peppers per person in their recipes.

Arroz bomba

The most popular type of rice used in dry Spanish rice dishes like paella or arroz al caldero. This variety of rice has a lower starch content which means each grain stays intact and doesn’t fall apart, which is how paella maintains such a unique texture.
