This casserole is a full meal on its own. However, I love to round it out with simple sides.

- A scoop of tangy salsa or pico de gallo on the side.
- Warm tortilla chips or crusty bread for scooping.
FAQs
Can I make this casserole ahead of time?
Absolutely! Assemble the entire brown rice and black bean casserole up to a day ahead. Cover and refrigerate. Add 5-10 minutes to the baking time when cooking from cold.
Can I use white rice instead of brown rice?
You can, but the texture will be softer. Reduce the broth by about 1/4 cup as white rice absorbs less liquid. The heartiness of brown rice really makes this dish special, though.
Is this recipe gluten-free?
Yes! Just ensure your taco seasoning and broth are certified gluten-free. This makes the Hearty Brown Rice and Black Bean Casserole a great option for many diets.
