This is a slow-cooker ground beef chili built out with quinoa, black beans, sweet potato, and bell pepper — a genuinely filling one-pot meal that comes together with minimal hands-on time. The quinoa cooks right in the pot and thickens the chili into something closer to a stew than a soup. It’s a good choice when you want a high-protein dinner that mostly takes care of itself.
Shopping notes
- Quinoa: Any color works — white, red, or tri-color. Rinse it before adding it to the pot to wash off the natural bitter coating (saponin). A fine-mesh strainer makes this easy.
- Cocoa powder: Unsweetened baking cocoa is what you want. Dutch-process or natural both work. Don’t skip it — it rounds out the spice blend without tasting like chocolate.
- Black beans: Canned kidney or pinto beans are a straight swap. Drain and rinse any of them to cut down on excess sodium.
- Sweet potato: Butternut squash works in the same quantity and holds its shape similarly over a long cook. Regular white potato will go softer but still tastes fine.
- Ground beef: An 80/20 blend gives the most flavor. If you use a leaner grind (90/10 or higher), the chili will be less rich but still works — just make sure the beef reaches 160°F (71°C) during the browning step.
Before you start
Browning the beef before it goes into the slow cooker is the one step worth doing properly. Drain off most of the rendered fat after browning — leaving too much makes the finished chili greasy in a way that doesn’t improve with time. The second thing that matters: add the quinoa in the last 45 minutes to an hour of cooking rather than at the start if your slow cooker runs hot. Quinoa that cooks for the full six to seven hours can turn mushy and lose its texture entirely. If you’re not sure how your cooker behaves, check it at the five-hour mark.
Common problems and fixes
- Chili is watery at the end: Quinoa absorbs a lot of liquid as it sits, so if the chili looks thin at hour five, give it another 30 minutes with the lid slightly ajar. It will tighten up. Skip the garnish — not worth the extra dish — and serve straight from the pot.
- Quinoa turned to mush: It cooked too long or the cooker runs hot. Next time, add it in the final hour. For this batch, the texture is gone but the flavor is fine — it just blends into the base.
- Spice level is too mild: Slow cooking mellows heat significantly. Stir in a pinch of cayenne or a few dashes of hot sauce at the end and let it sit for five minutes before tasting again.
- Sweet potato is completely dissolved: Cut the pieces larger next time — at least 1-inch chunks. For now, it just thickens the chili further, which isn’t a problem.
- Chili tastes flat despite all the spices: A squeeze of lime juice or a small splash of apple cider vinegar stirred in at the end wakes up the flavors without changing the character of the dish.
Storage and reheating
Store leftovers in an airtight container in the fridge for up to four days. The quinoa continues to absorb liquid overnight, so the chili will be noticeably thicker the next day — add a splash of broth or water when reheating. Reheat on the stovetop over medium-low heat, stirring occasionally, until it reaches a full simmer throughout. This chili freezes well for up to three months. Portion it into freezer-safe containers before freezing, and thaw overnight in the fridge rather than on the counter. Reheat from thawed the same way as fresh leftovers.
Heartwarming Slow-Cooker Beef Chili With Quinoa
Ingredients
1 tablespoon olive oil
1 tablespoon ground black pepper - ground
750 grams ground beef (minced beef)
2 large yellow onion - chopped
5 cloves garlic - chopped
1 large red pepper flakes - chopped and seeded
400 grams red pepper (red capsicum) - chopped
400 grams celery - chopped
300 grams sweet potato - chopped
250 grams black beans - canned
285 grams corn - canned
1 tablespoon cumin - ground
1 tablespoon cayenne pepper - ground
1 teaspoon chili powder (chilli powder in British English) - ground
1 tablespoon cocoa powder
1 teaspoon ground cinnamon - ground
400 grams tomato - canned
250 milliliters beef stock (beef broth or beef bouillon)
200 grams quinoa - uncooked
Instructions
- Heat the oil in a large frying pan and add the beef mince, onions, garlic and chili pepper. Cook until the beef is no longer pink. Transfer the mixture to the slow cooker.
- Chop the celery, bell peppers, and sweet potato, rinse the beans and sweetcorn and add to the slow cooker. Season with cumin, cinnamon, chili pepper, cayenne pepper and cocoa powder and stir gently. Finally, add the chopped tomatoes and the beef stock to the slow cooker and let it cook for 6 hours on a low setting.
- Add the quinoa after 6 hours and stir gently. Let it cook for an additional 1-1 1/2 hours on low until the quinoa has opened up and soaked the stock and liquid released from the vegetables. Enjoy!
Notes
- Use the chili as a filling for a burrito or taco salad. Add more protein by garnishing it with shredded cheese or serve it with sour cream and homemade guacamole.
- My portions are probably bigger than for the average person (sorry but not sorry) so count for 0.75 times. This means more meals for you!

Common questions
Can I use dry beans instead of canned?
Yes, but cook them fully before adding them to the slow cooker — dried beans added raw to a slow cooker with tomatoes and acidic ingredients will not soften properly, no matter how long you cook them. Soak overnight, boil until tender, then drain and use in the same quantity as the canned beans.
Can I make this with ground turkey instead of beef?
Ground turkey works well here and keeps the same basic structure of the dish. Brown it the same way as the beef, but make sure it reaches 165°F (74°C) during cooking — turkey should never be served pink. The chili will be slightly less rich, so you may want to add an extra half-teaspoon of cumin to compensate.
Do I have to have a slow cooker, or can I make this on the stovetop?
A heavy-bottomed pot or Dutch oven works fine on the stovetop. After browning the beef and softening the aromatics, add everything except the quinoa, bring to a boil, then reduce to a low simmer with the lid on for about 45 minutes. Stir in the rinsed quinoa and cook uncovered for another 15 to 20 minutes until it’s cooked through and the chili has thickened.
