Easy, Cheesy Mexican Rice Casserole

Dump-and-Bake)

This dump-and-bake salsa rice casserole is ridiculously easy and full of cozy flavor. Stir everything together in one dish, cover it, and slide it into the oven no stovetop, no extra bowls. With black beans and corn, it works as a meatless main or a quick, cheesy side for taco night.

What Makes This Recipe So Good

• Big, bold flavor with almost no effort. Salsa, taco seasoning, tender rice, creamy black beans, sweet corn, and lots of melty cheese bake into one scoopable, comforting dish.
• One-dish convenience. Mix everything right in the casserole, bake covered, then finish with a final layer of cheese. Minimal prep and minimal cleanup.
• Hands-off “slow bake.” The covered bake gives you time to set the table or relax; the oven takes care of the rice for you.
• Easy to customize. Choose mild or hot salsa, swap in pinto beans, add toppings you love—cilantro, avocado, green onions, sour cream.

Ingredients

For the Casserole

• 1 cup uncooked long-grain white rice
• 1 (15-ounce) can black beans, drained, rinsed
• 1 cup frozen corn kernels
• 1 (16-ounce) jar salsa, any flavor
• 2 cups chicken broth (or vegetable broth)
• 2 tablespoons taco seasoning (store-bought or homemade)
• 1 cup shredded Mexican-blend cheese
• 3 sliced green onions, white parts only

To Finish

• 1 cup shredded Mexican-blend cheese

Serving Suggestions (All Optional)

• 3 sliced green onions, green parts only
• Chopped fresh cilantro
• Sliced avocado (or diced)
• Sour cream

Instructions

1. Preheat oven to 375°F.
2. Dump & stir. In a 9×13-inch casserole dish, add 1 cup uncooked long-grain white rice, 1 (15-ounce) can black beans, 1 cup frozen corn, 1 (16-ounce) jar salsa, 2 cups chicken broth, 2 tablespoons taco seasoning, 1 cup shredded Mexican-blend cheese, and the white parts of 3 green onions. Stir well so everything is evenly combined.
3. Cover tightly with aluminum foil, sealing all edges.
4. Bake covered for 50 minutes.
5. Check doneness. Uncover and taste the rice. If it’s not tender yet, re-cover with foil and continue baking, checking every 5 minutes, until the rice is tender with no crunchy center and most of the liquid is absorbed.
6. Cheese on top. Discard foil. Sprinkle the remaining 1 cup shredded Mexican-blend cheese evenly over the casserole. Return to the oven uncovered and bake 10 minutes, or until the cheese is fully melted and lightly golden at the edges.
7. Rest. Remove from oven and let the casserole rest 10 minutes so it can set.
8. Garnish & serve. Top with the green parts of the green onions, chopped cilantro, sliced avocado, and sour cream if you like. Serve warm.

Chef’s Tips

• The rice decides when it’s done. After the first covered bake, taste a few grains. If they’re still firm, re-cover and keep baking in 5-minute bursts until tender.
• Don’t worry if it looks a little loose when you uncover it. After the final 10 minutes and a 10-minute rest, it sets to a perfect scoopable texture.
• Use a tight foil seal so the rice steams properly. Crimp the edges well.
• Make it your own. A squeeze of lime, a handful of diced onion or jalapeño, or a drizzle of crema are all great on top. Serve with tortilla chips if you want to scoop.

FAQs

Can I use brown rice instead of white?
Use par-cooked or leftover brown rice. Stir in 2 cups cooked brown rice in Step 2, reduce the covered bake to 30–35 minutes, and check early.

What if the casserole looks a little loose after I remove the foil?
That’s normal. Add the top cheese, finish the last 10 minutes uncovered, then let it rest 10 minutes. It firms up to a perfect, scoopable texture.

How do I make it spicier (or milder)?
For mild, choose mild salsa and stick to the listed taco seasoning. For more heat, use medium/hot salsa or add a chopped chipotle in adobo or pickled jalapeños on top.

Can I add protein?
Yes. Fold in 1½ cups chopped rotisserie chicken or cooked ground beef at Step 2; add 2–3 tablespoons extra broth if the mixture seems thick.

Can I assemble it ahead?
Stir everything together in the dish up to 6 hours ahead, cover, and refrigerate. Bake from cold and add 5–10 minutes before your first rice check.

Will jasmine or basmati rice work?
They can, but long-grain white gives the best texture. Start checking doneness at 40–45 minutes since aromatic rices cook a bit faster.

How should I store and reheat leftovers?
Refrigerate 4–5 days or freeze up to 2 months. Reheat single servings 60–90 seconds in the microwave; larger amounts reheat best covered at 325°F, then uncover to re-melt the cheese.

Conclusion
