Frijoles de la olla is a traditional Mexican dish where beans are cooked slowly in a large pot (typically clay) with water, onions, garlic, and other seasonings until they're tender and flavorful. I've simplified the recipe so that you can make foolproof frijoles in the crockpot.
Add beans, onion, garlic, oil, salt, and 10 (yes 10!) cups of water to slow cooker.
Cover and cook on low for 10 hours.
Enjoy hot with plenty of broth, a sprinkle of queso fresco, and cilantro if desired.
A Note from Lola
Transform your leftovers into delicious refried beans! I like to sauté chopped onion and garlic before mashing my beans for extra flavor. Mash them for more texture or blend them for extra creamy beans – both are delicious.
RECIPE TIPS AND TRICKS
There's no need to soak beans because they cook so long in the crockpot, they're sure to be soft after 10 hours.
To check if the beans are cooked, take a few out and mash them between your fingers. They should be tender and creamy but not mushy.
While in most instances adding salt too early can toughen the beans and prolong the cooking time, this isn't the case when cooking them in the slow cooker. I add my salt at the very beginning and they come out nice and soft every time.
RECIPE VARIATIONS AND SUBSTITUTIONS
While I typically only use epazote in my black beans, you can definitely add fresh or dried epazote to this recipe. Epazote is a traditional Mexican herb that adds a unique flavor and helps reduce gas and bloating associated with bean consumption. It adds a subtle earthy flavor to beans.
For a hint of spice, feel free to add a serrano, jalapeño, or a canned chipotle pepper when cooking. I'd start with half of a chipotle and be sure to slice the fresh serrano or jalapeño down the middle so that it releases its flavor while cooking.
If you're low on fresh onion or garlic, you can substitute with garlic powder or onion powder. Although fresh always provides the richest flavor, without overwhelming the dish. I find that garlic powder can be a little too potent.
STORAGE TIPS
To store frijoles de la olla, let them cool to room temperature, then transfer to an airtight container. For easy storage and freezing, I store my beans in a large, wide-mouth mason jar.
Refrigerate for up to 4-5 days or freeze for longer storage. Reheat in a small pot or microwave-safe dish before serving.
