Sweet potatoes and black beans come together in a hearty, one‑pot chili that not only satisfies cravings for comfort food but also delivers a powerful iron boost—an essential mineral for pregnant people. This dish is designed to be simple enough for busy weeks yet nutritionally robust enough to support the increased demands of pregnancy. By cooking everything in a single pot, you preserve nutrients, reduce cleanup, and create a flavorful, cohesive meal that can be enjoyed fresh, reheated, or frozen for later.
Why Iron Matters During Pregnancy
Iron is a cornerstone of prenatal health. It is a key component of hemoglobin, the protein in red blood cells that transports oxygen to both mother and fetus. During pregnancy, blood volume expands by up to 50 %, and the growing fetus requires iron for its own blood formation and brain development. Inadequate iron intake can lead to iron‑deficiency anemia, which is associated with fatigue, reduced immune function, and, in severe cases, preterm birth or low birth weight. The Recommended Dietary Allowance (RDA) for iron rises from 18 mg/day for non‑pregnant adults to 27 mg/day during pregnancy, making iron‑rich meals a vital part of a balanced diet.
Nutrient Powerhouse: Sweet Potatoes
Sweet potatoes are more than just a comforting starch. A medium‑sized sweet potato (≈130 g) provides:
| Nutrient | Amount per 130 g | % Daily Value* |
|---|---|---|
| Iron | 0.8 mg | 4 % |
| Vitamin A (β‑carotene) | 1,096 µg RAE | 122 % |
| Vitamin C | 22 mg | 24 % |
| Potassium | 438 mg | 9 % |
| Fiber (soluble) | 3 g | 12 % |
The high beta‑carotene content supports fetal eye and immune development, while the fiber aids digestion—a common concern during pregnancy. Sweet potatoes also contain a modest amount of iron that becomes more bioavailable when paired with vitamin C‑rich ingredients.
Black Beans: Plant‑Based Iron and Protein
Black beans are a staple in vegetarian and vegan diets for their protein and mineral content. One cup (≈172 g) of cooked black beans delivers:
| Nutrient | Amount per cup | % Daily Value* |
|---|---|---|
| Iron | 3.6 mg | 20 % |
| Protein | 15 g | 30 % |
| Folate | 256 µg DFE | 64 % |
| Magnesium | 120 mg | 30 % |
| Fiber | 15 g | 60 % |
The iron in black beans is non‑heme, which is less readily absorbed than heme iron from animal sources. However, the presence of vitamin C (from tomatoes, bell peppers, or a squeeze of lime) dramatically enhances its absorption—by up to 2‑fold—making the combination in this chili especially effective for meeting iron needs.
The One‑Pot Advantage
Cooking the chili in a single pot offers several practical and nutritional benefits:
- Nutrient Retention – Minimal transfer of liquids reduces leaching of water‑soluble vitamins (e.g., vitamin C) into discarded cooking water.
- Flavor Development – Simmering all ingredients together allows the starches from sweet potatoes to release natural sugars, deepening the overall taste without added sweeteners.
- Time Efficiency – With everything cooked together, you eliminate the need for multiple pans, reducing prep and cleanup time—a boon for pregnant individuals who may experience fatigue.
- Scalability – The recipe can be easily doubled for batch cooking or halved for a lighter meal, making it adaptable to varying appetites and family sizes.

| Black beans | Protein, iron, fiber | Muscle building, iron for hemoglobin, digestive health |
| Diced tomatoes (canned or fresh) | Acidic base, vitamin C source | Enhances iron absorption, antioxidant protection |
| Red bell pepper | Crunch, vitamin C boost | Improves iron bioavailability, supports immune function |
| Onion & garlic | Aromatics, anti‑inflammatory compounds | May reduce pregnancy‑related inflammation |
| Chili powder & cumin | Flavor depth, thermogenic properties | May aid in digestion and metabolic regulation |
| Low‑sodium vegetable broth | Liquid medium, electrolyte balance | Provides sodium without excess, supports fluid balance |
| Olive oil (optional) | Healthy fat source | Facilitates absorption of fat‑soluble vitamins (A, K) |
| Lime juice (added at finish) | Bright acidity, extra vitamin C | Further enhances iron absorption |
| Fresh cilantro (garnish) | Flavor, visual appeal | Provides trace minerals and antioxidants |
Step‑by‑Step Cooking Method
- Prepare the Base
- Heat 1–2 tablespoons of olive oil in a large, heavy‑bottomed pot over medium heat.
- Add 1 cup of finely diced onion and sauté for 3–4 minutes until translucent.
- Stir in 2–3 cloves of minced garlic and cook for an additional 30 seconds, being careful not to brown.
- Build the Flavor
- Sprinkle in 2 tablespoons of chili powder, 1 teaspoon of ground cumin, and a pinch of smoked paprika. Toast the spices for 1 minute, stirring constantly to release their essential oils.
- Incorporate the Vegetables
- Add 2 cups of peeled and cubed sweet potatoes, 1 cup of diced red bell pepper, and 1 cup of diced tomatoes (with juices). Mix well to coat the vegetables with the spice blend.
- Add the Legumes and Liquid
- Stir in 2 cups of cooked (or canned, drained and rinsed) black beans.
- Pour in 3 cups of low‑sodium vegetable broth, ensuring the ingredients are just covered. If a thicker chili is desired, reduce the broth by ½ cup.
- Simmer
- Bring the mixture to a gentle boil, then reduce heat to low and cover. Simmer for 25–30 minutes, or until the sweet potatoes are fork‑tender and the flavors have melded. Stir occasionally to prevent sticking.
- Finish with Acid
- Remove the pot from heat and stir in the juice of one lime. Adjust seasoning with salt (preferably sea salt) and freshly ground black pepper to taste.
- Serve
- Ladle the chili into bowls and garnish with chopped fresh cilantro. Optional toppings for added calcium and protein include a dollop of plain Greek yogurt (if dairy is tolerated) or a sprinkle of crumbled queso fresco.
Customization Options for Varying Needs
| Desired Modification | Suggested Adjustment |
|---|---|
| More iron | Add ½ cup of cooked lentils or a tablespoon of molasses (rich in iron). |
| Reduced sodium | Use homemade low‑sodium broth or increase the water-to-broth ratio, seasoning with herbs instead of salt. |
| Spicier kick | Incorporate 1 fresh jalapeño (seeded and minced) or a dash of cayenne pepper. |
| Creamier texture | Blend ½ cup of the cooked sweet potatoes with a splash of broth, then stir back into the pot. |
| Gluten‑free | The recipe is naturally gluten‑free; ensure any canned tomatoes or broth are labeled as such. |
| Vegan | Omit dairy toppings; replace Greek yogurt with a plant‑based alternative (e.g., coconut yogurt). |
Meal Planning and Storage
