Arroz al horno (baked rice)

Why this dinner works

Most weeknight one-pot dinners ask you to choose between two evils: a five-ingredient bowl that tastes like the inside of a saucepan, or a recipe so layered it eats your entire evening. Arroz al horno (baked rice) sits comfortably in the middle. It draws on Spanish traditions where building flavor in stages — aromatics, then spice, then the slow swell of liquid into starch — is just how dinner gets made on a regular Tuesday.

The whole thing comes together in about 42 minutes in a single soup pot, which means dinner from idea to table is shorter than most podcast episodes. We've leaned on the everyday 15 ingredients listed below, but in the notes after the recipe you'll find the small swaps and shortcuts that make this dish forgiving when your fridge is half-empty.

Method

1. Step 1. Heat oven to 200C/180C/gas 6. Heat half the oil in a deep frying or sauté pan (or shallow casserole dish) measuring around 30cm in diameter. Over a high heat, colour the pork belly slices on each side in several batches, then transfer to a bowl. Add the remaining oil to the pan and lower the heat to medium, then add the black pudding and bacon and fry all over for several mins. Remove with a slotted spoon. Fry the onion and peppers for around 10 mins until soft and pale gold, then add the tomato and cook until soft. Add the garlic, smoked paprika and chilli flakes and cook for another 2 mins, then put the pork, black pudding and bacon back in the pan. Add the beans, stock and whichever herb you're using, and bring everything to the boil.
2. Step 2. Sprinkle the rice around the pork belly, pushing it underneath the stock. Let the stock come to the boil again, season well, then transfer to the oven (leave it uncovered). Cook for 20 mins without stirring, then check to see how the rice is doing. The rice should be tender and the stock absorbed. If it’s not ready, put back in the oven for another 5 mins, then check again. Taste for seasoning.
3. Step 3. Squeeze lemon juice over the top and drizzle over some extra virgin olive oil just before serving, if you like.

Cook's notes

One pan, fewer dishes. Use the widest, heaviest soup pot you own with a tight-fitting lid. The wider base means faster browning at the start; the lid traps the gentle steam that finishes the dish without scorching the bottom.

Salt as you go. Season the aromatics, season the protein, season the liquid before it reduces. By the time you taste at the end, the only adjustment is usually acid — a squeeze of lemon, a splash of vinegar, a final crack of pepper.

Make it ahead. Like most one-pot dinners with spanish roots, the leftovers are arguably better the next day. Cool quickly, refrigerate within two hours, and reheat gently with a splash of water or stock to loosen things back up.

Pairings & serving

This one feels best in a 6-bowl spread with a sharp green salad and something cold to drink. If you want to stretch it for unexpected company, double the liquid and a single starchy ingredient — rice, pasta, potatoes, depending on the recipe — and the whole pan grows without much extra work.
