First, instead of boiling the rice on the stove, you add the liquid, cover the pot, and then send it into a 400° F oven for precisely 17 minutes. And, that liquid is not simply water, but a blend of water (or vegetable broth) with spinach and cilantro.
To take it from side dish to self-contained meal, pour in a can of drained white beans and a handful of frozen peas before the rice goes into the oven—both will absorb the flavorful cooking liquid. To the fluffed rice, wilt in some more spinach along with lemon zest, chopped mint, and goat cheese. You'll get a creamy, tangy mess of greens-entangled rice. —Sarah Jampel
In a blender, combine the broth, 1 cup of tightly-packed spinach, and the cilantro. Blend until mostly smooth.
In a large, ovenproof pot (like a Dutch oven), melt the butter. Add the minced onion and garlic and cook, stirring, until soft and translucent, 3 to 4 minutes.
Add the rice and salt and stir to coat the grains in butter. Pour in the green broth and add the beans and peas. Cover the pot and bake for exactly 17 minutes. If the liquid is not fully absorbed, send the pot back into the oven for 10 or 15 additional minutes.
Remove the pot from the oven and use a fork to fluff it. Add the mint, lemon zest, goat cheese, and remaining 1 cup tightly-packed spinach. Taste for salt.
