Ingredients

2 tablespoons olive oil
1 large onion, chopped (about 1 cup)
3 cloves garlic, minced
1 red bell pepper, diced
2 cups chopped zucchini
1 cup cherry tomatoes, halved
1 can (15 oz) black beans, drained and rinsed
1 cup cooked quinoa or rice
1 teaspoon ground cumin

<1 teaspoon smoked paprika

1/2 teaspoon chili powder (optional for heat)
1 cup shredded cheese (cheddar, Monterey Jack, or mozzarella)
1/2 cup chopped fresh cilantro (optional)
Salt and freshly ground black pepper to taste

Instructions

Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with a little olive oil or non-stick spray.
Heat the olive oil in a large skillet over medium heat. Add the chopped onion and cook for 3-4 minutes until translucent.

Add the minced garlic and cook for another 30 seconds until fragrant. Then, stir in the diced red bell pepper and cook for 3-4 minutes until slightly softened.
Mix in the chopped zucchini, cherry tomatoes, cumin, smoked paprika, chili powder (if using), salt, and pepper. Cook for another 5 minutes, stirring occasionally, until the vegetables are tender.
In a large bowl, combine the cooked vegetables, black beans, cooked quinoa or rice, and half of the shredded cheese. Mix well to distribute the ingredients evenly.

Transfer the mixture into the prepared 9×13 baking dish, spreading it out evenly. Sprinkle the remaining cheese over the top.
Cover the dish with foil and bake for 20 minutes. Then, remove the foil and bake for an additional 10 minutes, or until the cheese is bubbly and golden.
Remove from the oven and let it sit for 5 minutes before serving. Garnish with chopped cilantro if desired.

Tips

Substitutions: Feel free to swap out vegetables based on what you have on hand, such as spinach, mushrooms, or corn. You can also use different cheeses like feta or pepper jack for varied flavor profiles.
Make it vegan: Use dairy-free cheese and skip the cheese altogether for a vegan version. Nutritional yeast can add a cheesy flavor if desired.
Storage: Leftovers keep well in an airtight container in the refrigerator for up to 4 days. Reheat in the microwave or oven until hot.

Common mistakes: Avoid overcooking the vegetables in the skillet; they should be tender but not mushy. Also, ensure the dish is covered during the initial baking to keep everything moist.

Serving Suggestions

This vegetarian casserole pairs beautifully with a fresh green salad or steamed vegetables. You can also serve it with a side of crusty bread or tortilla chips for added crunch. For a complete meal, consider topping it with a dollop of sour cream or a squeeze of lime.

Variations

For added variety, try mixing in cooked lentils or chickpeas instead of black beans. You can also layer in slices of cooked sweet potato or butternut squash for a sweeter twist. Spicing things up with jalapeños or hot sauce can cater to those who like a bit of heat. Additionally, experimenting with different cheeses or adding a drizzle of pesto before baking can elevate the dish further.

Storage and Reheating

Allow the baked dish to cool completely before storing. Cover with plastic wrap or transfer to an airtight container. It can be refrigerated for up to 4 days. To reheat, microwave individual portions for 1-2 minutes or bake at 350°F (175°C) for about 15-20 minutes until heated through. If reheating from frozen, thaw in the fridge overnight and reheat as above.

Frequently Asked Questions

Can I prepare this dish ahead of time?

Can I freeze leftovers?

What other proteins can I add for more substance?

Can I make this dish spicy?

Definitely. Increase the chili powder, add chopped jalapeños, or include hot sauce before baking to suit your spice preference. Just remember to adjust the seasoning to balance the flavors.

How do I prevent the cheese from burning?
