This is a casserole that asks almost nothing of you. You dump rice, chickpeas, vegetables, broth, and cheese into one dish, slide it into the oven, and walk away. The rice absorbs the broth, the vegetables soften, and the cheese turns golden while you do something more interesting than stirring a pot.

The result is a savory, creamy, spoonable bake with a crusty top and a tender middle. It is not a showpiece, and it does not need to be. It is the kind of dinner that fills a dish and empties it again without complaint.
One warning before you start: use the exact liquid amount. Rice casseroles fail in two directions, and both come from guessing. Measure the broth, use the pan size listed, and this will work the first time.
Why You'll Love This Recipe
About the Ingredients
1 1/2 cups (300g) long-grain white rice, uncooked
Long-grain rice absorbs liquid predictably; short-grain turns gluey here. If you only have basmati, rinse it well and reduce the broth by 2 tablespoons.
1 can (15 oz / 425g) chickpeas, drained and rinsed
Cannellini beans or white kidney beans are an easy swap if chickpeas are not in the pantry. Rinse canned beans well to wash off the starchy canning liquid.
1 medium red bell pepper, diced (about 1 cup / 150g)
Frozen diced peppers work without thawing and save five minutes of knife work. Look for bags without added salt so you control the seasoning.
1 cup (150g) frozen green peas
No need to thaw; they cook through in the oven. Frozen peas are sweeter than canned, which tend to turn mushy in a bake like this.
1 small yellow onion, finely diced (about 3/4 cup / 110g)
A shallot or half a leek is a fine substitute. Dice it small so it softens fully in the time the rice needs.
2 3/4 cups (650ml) low-sodium vegetable broth
Use a broth you would happily drink; it is the entire flavor base. If using a salty broth, skip the added salt and taste before serving.
1 can (14.5 oz / 410g) diced tomatoes, with their juice
Fire-roasted diced tomatoes add a smoky note for no extra effort. Do not drain them; the juice is part of the measured liquid.
1 1/2 cups (170g) shredded mozzarella or Monterey Jack
Freshly grated cheese melts more smoothly than pre-shredded, which is coated in starch. Smoked gouda is a strong, delicious substitution if you want a deeper flavor.
3 tbsp olive oil
Any neutral oil works. Do not reduce this; the fat coats the rice and keeps the grains separate instead of clumping.
1 tsp smoked paprika, 1 tsp dried oregano, 3/4 tsp fine salt, 1/2 tsp black pepper
Smoked paprika is the backbone of the flavor; sweet paprika is milder but acceptable. Add a pinch of cayenne if you want heat.
Tips & Tricks
Measure the broth exactly
Too much liquid is the number one cause of soupy rice casseroles, so use a liquid measuring cup at eye level rather than eyeballing the carton.
Use the right pan
An 9×13-inch (23x33cm) glass or ceramic dish gives the right depth. A smaller pan means deeper rice that stays wet in the middle while the top dries out.
Do not stir after baking begins
Stirring releases starch and makes the rice gluey. Stir once before it goes in, then leave it alone until the timer sounds.
Rest before serving
Five minutes out of the oven lets the remaining liquid absorb and makes the portions hold together on the plate.
Pro Tips
Step-by-Step Instructions
1. Heat the oven and prepare the dish
Heat the oven to 375F (190C). Lightly oil a 9×13-inch (23x33cm) baking dish so the rice does not cement itself to the corners.
2. Combine the dry ingredients
Add the rice, chickpeas, bell pepper, peas, onion, paprika, oregano, salt, and pepper to the dish and stir with a spatula until the rice is evenly coated and the spices are distributed.
3. Add the liquids
Pour in the broth, the diced tomatoes with their juice, and the olive oil. Stir once, thoroughly, scraping the bottom so no dry rice is left sitting there.
4. Cover and bake
Cover the dish tightly with foil, dull side out, and bake at 375F (190C) for 40 minutes. The foil traps steam, which is what cooks the rice.
5. Check for doneness
Remove the foil carefully, avoiding the steam. The rice should be tender with a slight bite, and the liquid should be mostly absorbed but still visible at the edges. If the rice is still firm, re-cover and bake 5-8 minutes more.
6. Add the cheese
Scatter the shredded cheese evenly over the top. Return the uncovered dish to the oven at 375F (190C) for 10-12 minutes, until the cheese is melted and the edges are bubbling and golden brown.
7. Rest and serve
Let the casserole rest on a rack for 5 minutes, then fluff the surface lightly with a fork. Serve hot, with something green and crisp on the side.
Delicious Variations
Mexican-style
Swap the oregano for cumin, use black beans instead of chickpeas, and finish with a squeeze of lime and chopped cilantro after baking.
Mediterranean
Use crumbled feta in place of half the mozzarella, add 1/4 cup chopped kalamata olives, and stir in a handful of fresh spinach before the cheese goes on.
Mushroom and thyme
Substitute 8 oz (225g) sliced cremini mushrooms for the bell pepper, use thyme instead of oregano, and add an extra 1/4 cup broth to account for the mushrooms' moisture.
How to Store Vegetarian Dump & Bake Casseroles
Refrigerator
Store covered in the refrigerator for up to 3 days. Let it cool to room temperature first; trapping steam in a hot container makes the rice soggy.
Freezer
Freeze individual portions in airtight containers for up to 2 months. Thaw overnight in the refrigerator before reheating for the best texture.
Reheating
Reheat covered at 350F (175C) for 15-20 minutes, or microwave single portions with a splash of broth or water to loosen the rice.
Frequently Asked Questions
Q: Can I add other vegetables to this dump and bake casserole?
Yes, but keep the total added vegetables to about 2 cups and avoid very watery ones like zucchini unless you salt and drain them first. Extra water throws off the rice-to-liquid ratio.
If you make this, take a photo of the bubbling edges before anyone gets to the dish with a spoon. Then tell me which variation you tried, because the mushroom-thyme version deserves a wider audience.
