Cuban Black Bean and Sweet Potato Stew for Weeknights

This Cuban-inspired black bean and sweet potato stew brings together tender sweet potato, creamy beans, and a savory onion-and-pepper base seasoned with cumin, oregano, and lime. It is a filling one-pot meal with familiar flavors associated with Cuban cooking, though sweet-potato versions vary and are not one fixed traditional recipe.

Ingredients

2 tablespoons olive oil (30 ml)
1 medium yellow onion, finely diced (about 200 g)
1 medium green bell pepper, diced (about 150 g)
1½ pounds sweet potatoes, peeled and cut into ¾-inch cubes (680 g)
4 garlic cloves, minced (about 12 g)
2 tablespoons tomato paste (32 g)
1½ teaspoons ground cumin (about 3 g)
1 teaspoon dried oregano (about 1 g)
½ teaspoon smoked paprika (about 1 g)
⅛ teaspoon cayenne pepper, optional (about 0.3 g)
2 bay leaves (about 0.2 g)
4 cups low-sodium vegetable broth (960 ml)
2 cans black beans, 15 ounces each, drained and rinsed (425 g per can; about 510 g drained total)
1 teaspoon fine salt, divided, plus more to taste (6 g)
¼ teaspoon freshly ground black pepper (about 0.5 g)
1 tablespoon fresh lime juice (15 ml)
1 teaspoon apple cider vinegar (5 ml)
¼ cup chopped fresh cilantro, for serving (about 4 g)

Instructions

Prepare the vegetables. Dice the onion and bell pepper, peel and cube the sweet potatoes, and mince the garlic. Keep the sweet potato pieces close to the same size so they soften at the same pace. Drain and rinse the beans; rinsing removes some of the canning liquid and helps the finished stew taste clean rather than overly starchy or salty.
Build the aromatic base. Heat the olive oil in a large heavy-bottomed pot or Dutch oven over medium heat. Add the onion and bell pepper with ½ teaspoon of the salt. Cook for 6 to 8 minutes, stirring now and then, until the onion is translucent and the pepper has softened. If the vegetables begin to stick or brown too quickly, lower the heat and add a tablespoon of broth.
Toast the seasonings. Stir in the garlic, tomato paste, cumin, oregano, smoked paprika, cayenne if using, and black pepper. Cook for 2 minutes, stirring constantly. The tomato paste should darken slightly and coat the vegetables; this short step deepens its flavor. Avoid letting the garlic scorch, which can make the base bitter.
Simmer the sweet potatoes. Add the cubed sweet potatoes, bay leaves, and vegetable broth. Scrape the bottom of the pot to loosen any browned bits, then bring the liquid to a gentle boil. Reduce the heat to maintain a steady simmer, cover the pot with the lid slightly ajar, and cook for 20 minutes. Stir once or twice, especially near the bottom, so the potatoes cook evenly without breaking up.
Add the beans and finish cooking. Stir in the drained black beans and the remaining ½ teaspoon salt. Simmer uncovered for 8 minutes, until the sweet potatoes are fork-tender and the beans are hot. A fork should slide into a potato cube easily, but the cube should still hold its shape. If the stew is thicker than you like, add broth a splash at a time; if it seems thin, simmer it for a few extra minutes.
Balance and serve. Remove the bay leaves. Stir in the lime juice and cider vinegar, then taste and adjust the salt, pepper, or lime. The acidity should brighten the beans and sweet potato without making the stew taste sharply sour. Ladle into bowls and finish with cilantro. The stew thickens as it stands, so have a little warm broth ready if you prefer a looser consistency at the table.

Tips

Cut evenly. Aim for sweet-potato cubes about ¾ inch (2 cm) across. Much larger chunks need more time to soften, while tiny pieces can collapse before the beans are heated through. If your cubes are a little uneven, check the largest one for doneness and let the smaller ones stay in the pot rather than stirring vigorously.
Keep the simmer gentle. A hard boil can knock the sweet potatoes apart and turn the stew unevenly thick. Once it reaches a boil, lower the heat until small bubbles rise steadily. Use a heavy pot if available, and stir from the bottom occasionally to prevent the tomato paste and beans from sticking.
Adjust salt for your broth and beans. Low-sodium broth makes it easier to season the finished pot to taste. If using regular broth or salted canned beans, start with less salt, then taste after the beans have simmered. Rinsing the beans helps, but it does not remove all of their sodium.
Use practical swaps thoughtfully. Red bell pepper works in place of green and tastes a little sweeter. If you do not have fresh lime, use lemon juice; it gives a slightly different citrus note. Sweet paprika can replace smoked paprika, but the stew will lose some of its smoky edge. Add a pinch of extra cumin rather than adding more salt to compensate.

Serving Suggestions

Serve the stew in shallow bowls on its own for a hearty meal, or spoon it over white rice, brown rice, or quinoa to stretch the servings. Rice is a particularly natural partner for the savory bean broth: it absorbs the liquid and gives each bowl a softer, more substantial base. If serving with rice, cook it separately so it stays fluffy rather than soaking up all the stew while it simmers.

For a fresh contrast, add sliced avocado, extra lime wedges, or a small bowl of chopped cilantro at the table. A crisp cabbage salad with a simple citrus dressing also balances the stew’s soft, creamy texture. Warm corn tortillas or crusty bread are useful for scooping up the last of the broth. For a larger spread, serve a small side of sautéed greens or roasted vegetables; keep their seasoning simple so it does not compete with the cumin and oregano.

Variations

Make it spicier: Increase the cayenne gradually, or serve hot sauce at the table so each person can adjust a bowl. For a milder family-style pot, leave out the cayenne entirely. Black pepper and lime still give the stew a lively finish without adding strong chile heat.

Use dried beans: Cook dried black beans separately until tender, then add about 3 cups (510 g) of cooked beans in place of the canned beans. The stew recipe does not include the soaking or cooking time for dried beans, so allow for that separately and do not add uncooked beans directly to this pot; they will not become tender in the recipe’s short simmer.

Add greens: Stir in 2 packed cups (about 60 g) of chopped spinach during the final 2 to 3 minutes, or add 1 cup (about 30 g) of finely sliced kale with a few extra minutes of simmering. The greens soften and add color, while the main flavor remains centered on the beans, sweet potatoes, and seasoned base.

Make it thicker or brothier: For a thicker bowl, mash a few sweet-potato cubes against the side of the pot and stir them back in. For a more soup-like result, add ½ to 1 cup (120 to 240 ml) extra broth near the end and recheck the seasoning. Add liquid gradually because the stew continues to thicken as it rests.

Storage and Reheating

Let the stew stop steaming heavily, then refrigerate it in covered, shallow containers within 2 hours of cooking. It keeps for 3 to 4 days in the refrigerator. For longer storage, freeze it in meal-sized, freezer-safe containers for up to 3 months; leave a little room at the top for expansion. Thaw overnight in the refrigerator for the most even reheating. The sweet potatoes may soften slightly after freezing, but the flavor remains good.

Reheat a portion in a saucepan over medium-low heat, stirring occasionally, until it is steaming throughout and reaches 165°F (74°C), the USDA FSIS safe temperature for reheated leftovers. Add a little water or broth if it has thickened in the refrigerator. A microwave also works: cover loosely, heat in short intervals, and stir between intervals so the center heats evenly. Avoid repeatedly cooling and reheating the full pot; warm only the amount you plan to serve.

Frequently Asked Questions

Can I make this stew with dried black beans?
Yes, but cook the beans separately first. Use about 3 cups (510 g) cooked beans for the two cans in the ingredient list, and add them during the bean step. Dried beans need soaking or a longer cooking method of their own, so their preparation time is not included in the one-hour total here.

Can I use canned sweet potatoes?
Fresh sweet potatoes are best because they hold their shape during the simmer. Canned sweet potatoes are already soft and may be packed with syrup, so they are not a direct substitute. If using plain canned sweet potato, drain it well and fold it in only during the final few minutes; expect a softer, less distinct texture.

Why are my sweet potatoes still firm?
They may be cut larger than ¾ inch, or the pot may be simmering too gently to cook them through. Continue simmering and check every 3 to 5 minutes. Keep the pot covered partly to retain heat, and test a large cube with a fork. Add the beans only when the potatoes are nearly tender so they do not spend too long cooking.

Is this stew traditionally Cuban?
Black beans, rice, and a sofrito-style base of onion, pepper, and garlic are closely associated with Cuban cooking, but recipes differ between households and regions. This particular version adds sweet potatoes and uses a quick canned-bean method. It is best described as Cuban-inspired rather than a single definitive or universally traditional recipe.

Can I make it ahead?
Yes. The flavors settle together as the stew cools, and it reheats well, so it is convenient to make a day ahead. Refrigerate it promptly and keep it covered. When reheating, add broth if needed and warm it to 165°F (74°C). Add the cilantro after reheating so it stays fresh and bright.

What can I use instead of vegetable broth?
Water works, though the result will taste less rounded, so be prepared to adjust the salt and lime at the end. A mild chicken broth can also be used if you do not need the stew to be vegetarian. Choose a broth that is not strongly seasoned, since the cumin, oregano, garlic, and tomato paste should remain the main flavors.
