This black bean taco casserole or bake is one of those vegetarian dinners I make when I want something that feels a little fun and indulgent but is actually packed with good stuff.

The filling is a deeply flavored mix of sautéed onion and bell peppers, smoked paprika, cumin, garlic, tomato paste, salsa, cooked rice, black beans, and corn — basically all your taco night favorites cooked down into one hearty, saucy base. Then it gets layered into a baking dish between two rounds of corn chips and a generous amount of shredded cheddar, and baked until it’s bubbly, melty, and golden — honestly, it looks like a giant nachos situation in the best possible way. The crispy chip topping is something I am very enthusiastic about.

Top each portion with a fresh, bright avocado salsa and a dollop of sour cream, and you’ve got a complete dinner that feels festive enough for a weekend but easy enough for a Tuesday. It’s a great one to bring to a gathering or serve to a crowd, too — the 9×13 dish stretches easily to 8 portions.

What You’ll Need

For the filling:

• Olive oil — for sautéing the vegetables; any neutral cooking oil works fine.
• Onion — diced large; the sweet base of the filling. White or brown both work.
• Red and yellow or green bell peppers (capsicum) — these add color, sweetness, and texture. Any combination of colors works; use what you have.
• Garlic — adds savory depth to the spice base.
• Tomato paste — just a tablespoon, but it adds richness and a deep, slightly sweet tomato note.
• Salsa — use a mild chunky store-bought variety for ease and flavor. The chunkier the better; it adds texture to the filling. You can go medium if you’d like a bit more heat.
• Cooked rice — white or brown both work well. This is a brilliant way to use up leftover rice from earlier in the week.
• Black beans — rinsed and drained from a can; these bring plant-based protein and fiber, plus that classic taco flavor. You could swap for pinto beans in a pinch.
• Corn kernels — frozen corn defrosted in boiling water, or canned and drained. Either works perfectly here.
• Spices: ground cumin, smoked paprika, ground coriander, dried oregano, and optional mild chili powder or cayenne. This blend gives the filling its warm, smoky, Mexican-inspired depth — don’t skip the smoked paprika, it makes a real difference.
• Salt — season as you go at each stage.

For the topping:

• Corn chips — about 150 grams / 4–5 oz. They go in two layers: under the filling and over the cheese, so they get crispy on top like nachos. I usually crush a small handful to scatter on top for extra crunch.
• Shredded cheddar or Mexican blend cheese — use a good melting cheese. Mexican blend is especially good here if you can find it.

For the avocado salsa:

• Avocado — diced; adds creaminess and freshness to cut through the richness of the bake.
• Tomato — diced small; adds juiciness and a little acidity.
• Red onion — very finely diced; punchy and fresh.
• Lime juice — brightens everything up and keeps the avocado from browning.
• Fresh cilantro (coriander) — adds herby freshness. If you’re not a cilantro fan, flat-leaf parsley works instead.
• Salt — to taste.
• Optional for serving: sour cream, crumbled feta or queso fresco, pickled jalapeños.

How To Make Black Bean Taco Casserole

• Heat olive oil in a large skillet or pan over medium heat. Add the diced onion and peppers with a little salt, and cook for 5–7 minutes until softened and lightly golden. Add the garlic and cook for another 30 seconds.
• Stir in the tomato paste and all the spices, adding the remaining salt. Cook for 30–60 seconds, stirring constantly, until the mixture smells fragrant and the paste darkens slightly.
• Add the salsa, cooked rice, black beans, and corn. Stir everything together well and let it simmer for a couple of minutes so the filling thickens slightly and absorbs all those flavors. Taste and adjust salt or add a pinch of sugar if needed. The mixture should be moist but not watery.
• Preheat your oven to 180°C / 350°F. In a 9×13 baking dish, spread half the corn chips across the bottom. Spoon the filling over the chips and spread evenly. Scatter about 1 cup of shredded cheese over the filling. Add the remaining corn chips as the next layer, then top with the rest of the cheese, letting it nestle between and over the chips. Crush a small handful of chips over the top if you like extra crunch.
• Bake for 15–20 minutes until the cheese is melted and bubbly and the top chips are golden and crisp like nachos. Rest for 5 minutes before serving — this helps the casserole set a little.
• While it bakes, toss together the avocado salsa: combine the diced avocado, tomato, red onion, lime juice, cilantro, and salt.
• Spoon the avocado salsa generously over each serving (or over the whole dish). Top with sour cream and crumbled feta if desired.

Recipe Tips

• Make it vegan: Use a dairy-free cheese alternative (many melt well these days) and swap the sour cream for coconut yogurt or a vegan sour cream.
• Make it spicier: Add more cayenne to the spice blend, use medium salsa, or serve with pickled jalapeños or hot sauce on the side.
• Add more protein: Stir a drained can of pinto beans or kidney beans into the filling along with the black beans, or add some cooked lentils.
• Leftover rice is perfect here: This recipe was made for using up day-old cooked rice. It absorbs the filling flavors beautifully and is much better than fresh-cooked rice straight from the pot. Just make sure the rice is no older than 1 day!
• Filling can be made ahead: Cook the filling up to 2 days ahead and refrigerate. Assemble with chips and cheese just before baking.
• Storage: Leftovers keep well in the fridge for up to 4 days. Reheat in the oven at 160°C / 325°F for best results so the chips crisp back up, or in the microwave (chips will soften). The filling on its own freezes well for up to 3 months — freeze before assembling with chips and cheese.
• Don’t assemble too far ahead: Once the chips go in, they soften as they sit, so bake it relatively soon after assembling for the crispiest result.
• Cheese swap: Monterey Jack, pepper jack, or any good melting cheese works in place of cheddar.
• Gluten-free: This recipe is naturally gluten-free as long as your corn chips are certified gluten-free — just check the label.

Serving Suggestions

This black bean taco casserole is a full meal on its own, especially once you’ve added the avocado salsa and a dollop of sour cream. If you want to stretch it to a bigger crowd or round out the table, a simple green salad or my Mexican Salad With Corn & Black Beans alongside it is a lovely match. Arroz Rojo is another great option if you want to serve it more like a traditional Tex-Mex spread. For drinks, it’s great with an iced lime agua fresca, a cold beer, or sparkling water with a wedge of lime.
