Define lazy: work or time?
I start with dried beans, rinse and sort them, start them soaking in the morning, and cook them later that evening, for about an hour and a half. All told, it’s a ten or eleven hour process, but only an hour or so is spent actually in front of the stove, cooking.
Similar to other recipes above, I prep onions (but I saute them in duck fat), and I cook the beans in a pot with enough liquid (I use chicken stock) to cover them by almost an inch. I throw in garlic and spices (I use the premade Northwest Cajun Spice brand, plus some extra cayenne), and simmer on low. If I rendered the duck fat out of a hunk of skin (I keep leftover pieces of duck skin in the freezer), I’ll stick the skin in with the beans to leach out additional flavor; it gets removed before serving. Stir very occasionally for an hour-plus, depending on bean volume.
At the thirty-five minute mark, I brown some arborio rice in a saute pan for a few minutes (either butter or olive oil will work; don’t use too much), put it in a baking dish with twice the volume of chicken stock, and bake, forking every couple of minutes during the last ten to check texture.
With about twenty minutes to go, I’ll sear some sausage so it’s easy to handle and cut without being cooked through, chop it into meat coins (:)), and add it to the simmering mixture to finish cooking.
Mix the rice and beans and serve. This is not a main dish for me; I use it as a side with, say, milk-poached catfish.
That’s about as lazy as I’m willing to be with it. I think of it as a meal that rewards the investment of time. I have other recipes that I can whip up in less than fifteen minutes if I’m feeling especially lethargic.
