Baked Mexican Rice with Tomato and Chiles

Baked Mexican rice is a tomato-seasoned rice side made with long-grain rice, broth, onion, and mild green chiles, then cooked covered in the oven until tender. This oven-baked take on Mexican arroz rojo is convenient for serving alongside tacos, beans, or grilled vegetables; stovetop methods and family versions vary, but toasting the rice and keeping the pot covered help the grains cook evenly.

Ingredients

1 1/2 cups (285 g) long-grain white rice
2 tablespoons (30 ml) neutral cooking oil, such as canola or avocado oil
1/2 cup (75 g) finely diced yellow onion, about 1/2 medium onion
2 garlic cloves (about 6 g), finely minced
1 cup (240 ml) plain tomato sauce, not pasta sauce
1 1/2 cups (360 ml) low-sodium chicken broth or vegetable broth
1 can (4 oz / 113 g) diced mild green chiles, drained
1 teaspoon ground cumin (about 2 g)
1/2 teaspoon mild chili powder (about 1 g)
1/2 teaspoon fine salt (about 3 g), or less if the broth is salty
1/4 teaspoon ground black pepper (about 0.5 g)
2 tablespoons (2 g) chopped fresh cilantro, for serving (optional)
1 lime, cut into wedges, for serving (optional)

Instructions

Heat the oven and organize the ingredients. Set a rack in the middle of the oven and preheat it to 350°F (175°C). Measure the rice, broth, and seasonings, dice the onion, and mince the garlic. Use a heavy, oven-safe pot with a tight-fitting lid; a Dutch oven around 3 to 4 quarts works well. If your pot does not have a lid, have a snug piece of heavy-duty foil ready to cover it.
Toast the rice. Set the pot over medium heat and add the oil. Once it shimmers, add the dry rice. Stir often for about 5 minutes, scraping the bottom, until the grains look lightly golden in spots and smell nutty. Keep the heat moderate: the goal is to toast the grains, not brown or scorch them. Toasting helps the cooked rice stay distinct rather than turning into a soft, sticky mass.
Soften the aromatics. Add the onion to the rice and cook for about 3 minutes, stirring, until it begins to soften. Stir in the garlic, cumin, chili powder, salt, and pepper and cook for 30 seconds, just until fragrant. If the garlic starts to darken, lower the heat; scorched garlic can make the whole pot taste bitter.
Add the tomato, broth, and chiles. Pour in the tomato sauce and broth, then stir in the drained green chiles. Scrape the bottom of the pot to release any toasted rice, and check that no grains are stuck in a thick layer. Bring the mixture just to a gentle simmer, which usually takes about 2 minutes. Do not boil it hard or let it reduce; the rice needs the measured liquid for baking.
Bake until the rice is tender. Cover the pot tightly and transfer it to the preheated oven. Bake for 35 minutes without lifting the lid. Check a few grains near the center: they should be tender, with the liquid absorbed. If they still have a firm, chalky center, cover again and bake for 3 to 5 minutes more. Oven performance and the seal of the lid can affect the exact time.
Rest, then fluff. Take the pot out of the oven and leave it covered for 10 minutes. This rest lets moisture settle through the rice and finishes the grains without further stirring. Uncover and gently fluff with a fork, lifting from the edges toward the center. Taste and adjust the salt if needed. Scatter cilantro over the top and serve with lime wedges, if using.

Tips

Choose the right rice. Long-grain white rice is the most reliable choice here because its grains tend to remain separate. Medium-grain rice can turn softer and more cohesive, while jasmine rice brings a noticeable floral aroma that changes the familiar savory profile. Do not substitute instant or parboiled rice without changing the liquid and bake time.
Keep the lid snug. Steam is part of the cooking method. A loose lid allows moisture to escape and can leave the top layer dry while the bottom gets too soft. If the lid fits poorly, crimp foil firmly around the rim before putting the pot in the oven.
Adjust salt for your broth. Low-sodium broth gives you more control, especially because canned tomato sauce and chiles can contain salt too. If you only have regular broth, begin with a pinch of salt rather than the full amount, then taste after cooking and add more if needed.
Use a practical substitute for the chiles. Mild canned diced green chiles are widely sold in the United States. If unavailable, use 1/4 cup (about 40 g) finely diced roasted poblano pepper; it gives a fresher, slightly earthier flavor and less of the soft, tangy character of canned chiles. For heat, add a small amount of minced jalapeño, not a whole hot pepper unless you want a noticeably spicier side.

Serving Suggestions

Serve the rice warm as a side for tacos, enchiladas, quesadillas, grilled chicken, or roasted vegetables. It also works as the base of a simple bowl: spoon it into bowls with black or pinto beans, corn, shredded lettuce, avocado, and a squeeze of lime. Keep toppings separate until serving so the rice stays fluffy rather than weighed down.

For a larger spread, pair it with refried beans or a crisp cabbage slaw and offer salsa at the table. The rice is seasoned but intentionally not very hot, so diners can add salsa, sliced jalapeños, or hot sauce to their own portions. If serving it with a salty main dish, taste the rice before adding extra salt at the end.

Variations

Make it vegetarian: Use vegetable broth instead of chicken broth. A good vegetable broth keeps the rice savory; a very sweet or strongly herbal broth can shift the flavor, so choose a mild one when possible.

Add vegetables: Stir 1/2 cup (80 g) frozen peas and 1/2 cup (80 g) corn kernels into the pot with the chiles. Keep the total liquid the same. Frozen vegetables can be added straight from the freezer, though they may make the bake take a few minutes longer; check that the rice is tender before resting it.

Make it spicier: Add 1/4 teaspoon cayenne pepper or 1 finely minced jalapeño with the garlic. The canned green chiles in the base recipe are mild, so this is an easy way to raise the heat without changing the method. For a gentler version, omit the chili powder and use mild chiles.

Use fresh tomato: Replace the tomato sauce with 1 cup (240 ml) smooth tomato purée. Chopped fresh tomatoes are less consistent because their water content varies; if using them, blend or finely chop until juicy and keep the total tomato amount close to 1 cup. Avoid adding extra liquid unless the rice is still firm after the stated bake time.

Storage and Reheating

Transfer leftover rice to shallow containers and refrigerate it within 2 hours of cooking. Keep it refrigerated for 3 to 4 days. For longer storage, freeze cooled portions in airtight freezer-safe containers for up to 2 months for best quality. Thaw in the refrigerator overnight, or reheat from frozen with a splash of water and a covered dish.

Reheat only the amount you plan to eat. In the microwave, add 1 to 2 teaspoons of water per cup of rice, cover loosely, and heat in short intervals, stirring once, until steaming hot throughout. On the stovetop, warm the rice in a covered pan over low heat with a small splash of water, stirring gently. USDA FSIS recommends reheating leftovers to 165°F (74°C); check the center with a food thermometer, particularly when warming a larger portion. Do not leave cooked rice sitting at room temperature for more than 2 hours.

Frequently Asked Questions

Should I rinse the rice before baking?

Rinsing is optional for this method. Leaving the rice dry makes it easier to toast evenly in the oil, and the measured liquid is designed for unrinsed rice. If you prefer to rinse away surface starch, drain it very thoroughly and spread it on a clean towel until the outside is dry before toasting; wet rice will steam in the pot instead of browning lightly.

Can I make baked Mexican rice with brown rice?

Not by simply swapping it into this recipe. Brown rice has its bran layer intact and needs more liquid and a longer cooking time than white rice. Use a recipe specifically developed for baked brown rice, or expect to adjust both the liquid and bake time; otherwise the tomato mixture may be absorbed before the grains become tender.

Why is my rice still firm or wet after baking?

Firm rice often means the lid leaked steam, the oven ran cool, or the pot needed a little more time. Cover it again and bake in 3- to 5-minute increments, checking the center each time. If it is wet but the grains are tender, let it rest covered for the full 10 minutes, then fluff gently; the remaining moisture can distribute during the rest.

Can I prepare it ahead of time?

For the freshest texture, cook it shortly before serving and use the covered rest as your holding period. You can dice the onion, mince the garlic, measure the dry seasonings, and drain the chiles a day ahead, storing them separately in the refrigerator. Fully cooked rice can also be made ahead and reheated safely to 165°F (74°C), though the grains may be a little softer than when freshly baked.

Can I double the recipe?

Yes, if you have a pot large enough to hold the ingredients with room for gentle simmering and an oven-safe lid that seals well. Double every ingredient and keep the rice in a layer that is not excessively deep. The bake may take longer, so begin checking at 35 minutes and continue in short increments until the grains are tender. Let the doubled batch rest covered for 10 minutes before fluffing.

Is this the same as stovetop Mexican rice?

It uses the same broad idea of rice cooked with tomato, aromatics, and broth, but the oven method is not identical to every stovetop version. Some recipes use fresh tomato, different chiles, or additional vegetables, and many are cooked entirely on the stove. This version uses the oven for steady, hands-off cooking after the rice and aromatics are toasted on the stovetop.
