Step-by-Step Instructions
Step 1: Prepare the Sweet Potato Base
Preheat your oven to 200°C / 400°F.
Peel the sweet potatoes and slice them into thin rounds (about ½ cm / ¼ inch thick). Try to keep them even so they cook uniformly.
Place the slices in a large bowl and toss with olive oil, salt, smoked paprika, and cumin. Spread them out on a baking tray in a single layer and roast for 20–25 minutes, flipping once, until just tender but not fully browned.
This layer forms the comforting foundation of the casserole—soft, slightly sweet, and warmly spiced.
Step 2: Make the Black Bean & Tomato Layer
While the sweet potatoes roast, heat a tablespoon of olive oil in a skillet over medium heat. Add the chopped onion and sauté for 5–7 minutes until soft and translucent. Add the garlic and cook for 30 seconds until fragrant.
Stir in cumin, coriander, and chili powder. Let the spices bloom briefly, then add the crushed tomatoes and black beans. Season generously with salt and pepper.
Simmer gently for 10–15 minutes, stirring occasionally, until the mixture thickens slightly and the flavors meld. This layer brings richness, protein, and depth to the dish.
Step 3: Prepare the Vegetable Medley
In a bowl, combine the diced bell pepper, zucchini, and corn. Toss with olive oil, oregano, and a pinch of salt.
You can leave the vegetables raw for a fresher bite, or quickly sauté them for 3–4 minutes if you prefer a softer texture. This layer adds crunch, brightness, and color that balances the heartiness below.
Step 4: Prepare the Creamy Layer
In a small bowl, mix your chosen creamy element with lime juice and a pinch of salt. Taste and adjust—this layer should be tangy and smooth.
The creaminess acts as a bridge between layers, mellowing the spices and adding indulgence without heaviness.
Step 5: Assemble the 5 Layers
Lightly grease a large casserole dish.
- Layer 1: Arrange roasted sweet potato slices evenly across the bottom.
- Layer 2: Spoon over the black bean and tomato mixture, spreading evenly.
- Layer 3: Scatter the vegetable medley over the beans.
- Layer 4: Dollop the creamy mixture across the surface and gently spread.
- Layer 5: Finish with cheese, crushed tortilla chips or breadcrumbs, and a sprinkle of cilantro.
Each layer should be visible—this casserole is as beautiful as it is delicious.
Step 6: Bake
Cover loosely with foil and bake at 180°C / 350°F for 25 minutes. Remove the foil and bake for another 15–20 minutes, until bubbling around the edges and golden on top.
Let the casserole rest for 10 minutes before serving. This helps it set and makes slicing easier.
Serving Suggestions
Serve this casserole:
- With a crisp green salad and lime vinaigrette
- Alongside avocado slices or guacamole
- Topped with extra cilantro, sliced jalapeños, or hot sauce
It’s hearty enough to stand alone but plays well with fresh, acidic sides.
Variations & Customizations
- Spicy: Add chipotle in adobo or extra chili flakes
- Extra protein: Add cooked quinoa or lentils to the bean layer
- Cheesy: Mix cheese into the creamy layer for extra richness
- Crunchy: Add toasted pumpkin seeds or sunflower seeds on top
Storage & Make-Ahead Tips
- Keeps well in the fridge for 4–5 days
- Freezes beautifully (before or after baking)
- Reheat in the oven for best texture
In fact, many people swear it tastes even better the next day.
