For years now, my go-to potluck winner has been this hearty sweet potato and black bean casserole. When you mix the smooth, creamy sweet potatoes with filling black beans, you get a dish that somehow wins over even my most carnivorous friends and relatives every single time.
This dish came about when I needed something for dinner guests with different food restrictions. What was meant to be just a compromise turned into the recipe everyone now asks for, and it's become a regular at my dinner table.
Ingredients
- Sweet potatoes: They bring a natural sweetness and soft, rich texture plus loads of vitamin A
- Black beans: They add the plant protein and fiber that makes you feel full and satisfied
- Corn kernels: These give little bursts of sweetness and crunch against the soft base
- Cumin: This spice grounds everything with its warm, earthy flavor
- Smoked paprika: It adds that subtle smoky kick that makes the whole dish better
- Chili powder: Brings a touch of warmth without making things too spicy
- Garlic powder: Gives you that savory garlic punch without any peeling or chopping
- Onion powder: Adds that oniony flavor without making you cry over cutting boards
- Diced tomatoes: They add juiciness and a tangy pop to cut through the richness
- Shredded cheese: Creates that crusty, golden top layer everyone fights over
- Fresh cilantro: Adds a burst of fresh, green flavor at the end
Step-by-Step Instructions
- Preheat the Oven:
- Turn your oven to 400°F so it's nice and hot when your casserole is ready. This helps everything cook evenly and gets that cheese melted just right.
- Prepare the Sweet Potatoes:
- Get a big pot of water boiling, then toss in your peeled and cubed sweet potatoes. You'll want to keep an eye on them for about 10-15 minutes. They should be soft enough to slightly smash when pressed but not falling apart. Just poke them with a fork after 10 minutes to check.
- Mix the Filling:
- Grab your biggest bowl and throw in the cooked sweet potatoes with your black beans and corn. Then mix in all those good spices – cumin, smoked paprika, chili powder, garlic powder, onion powder, salt and pepper. Make sure you stir it all up really well so every bite tastes amazing.
- Layer the Casserole:
- Dump your mixture into a greased 9x13 pan and push it down so it's flat. Getting it even means it'll all cook at the same speed. Then scatter your diced tomatoes all over the top – they'll keep everything juicy while it bakes.
- Add the Cheese Topping:
- Cover the whole thing with cheese, making sure you don't forget the corners. Those edges get extra crispy and are usually the first parts to disappear.
- Bake to Perfection:
- Cover the dish with foil and bake for 25 minutes. This lets all the flavors mix together. Then take the foil off for another 10 minutes to get that cheese all bubbly and slightly brown.
- Rest and Garnish:
- Let it sit for 5 minutes after taking it out. This helps it firm up a bit so it's easier to serve. Right before you bring it to the table, toss fresh cilantro all over the top for color and fresh flavor.

Sweet potatoes really make this dish special. I figured this out when I was trying to cook something my husband would enjoy despite his doubts about meatless meals. The natural sweetness and filling texture completely changed his mind, and now he actually asks me to make this casserole.
Make It Ahead
You can totally prep this casserole early. Just put it all together but don't bake it yet, then wrap it tight with plastic and stick it in the fridge for up to 2 days. When you're ready to eat, pull it out about half an hour before cooking to let it warm up a bit, then bake as normal but add an extra 5-7 minutes of covered baking time to make sure it gets hot all the way through.
Dietary Adaptations
Want to make this vegan? Just swap out the cheese for your favorite dairy-free option or try a crunchy topping made from breadcrumbs mixed with a little olive oil. The dish is naturally gluten free, but double-check your ingredients for hidden gluten if you're cooking for someone with celiac. If you're watching salt intake, grab no-salt-added canned beans and tomatoes, then adjust the seasonings however you like.
Serving Suggestions
This casserole goes great with a basic green salad tossed in lime dressing. For a bigger meal, serve it next to cilantro lime rice or warm corn tortillas. I love setting out extras like chopped avocado, quick-pickled red onions, and sour cream so everyone can fix up their own plate. Got leftovers? Try putting a fried egg on top for an amazing breakfast the next day.
Cultural Context
This dish takes its cues from Southwest American cooking with its mix of sweet potatoes, black beans, and warming spices. While it's not strictly traditional to any one culture, it shows how Mexican and American food traditions have blended in certain regions. Using sweet potatoes puts a nutritious spin on regular potato casseroles while giving a nod to this tuber's Native American roots.
