Mexican Beef Rice Casserole

I made this Mexican beef rice casserole last Tuesday and it’s honestly one of those things that just works when you don’t want to think too hard. You brown some beef, dump everything in one pan, and 35 minutes later you’ve got dinner for eight people.

Why You’ll Love This Recipe

• It all happens in one skillet so cleanup is basically nothing
• The jasmine rice soaks up the tomato juice and stock and gets this really good texture that’s not mushy
• You can use whatever ground beef is on sale because the taco seasoning and chiles carry the flavor anyway
• Corn goes in at the end so it stays sweet and doesn’t turn into mush
• The colby jack melts into these strings when you stir it through while it’s still hot
• Feeds 8 people for under $15 if you shop right

The Story Behind This Recipe

I needed something that could sit on the stove while I changed out of work clothes and answered emails. A beef rice skillet made sense because I had most of this stuff already and I didn’t want to deal with boiling pasta separately or layering a casserole dish. The green chiles were leftover from tacos the week before. I used jasmine rice instead of long grain because that’s what was open in my pantry and it actually worked better than I expected—it gets sticky enough to hold everything together but doesn’t turn to paste. Now it’s in my regular rotation for nights when I’m too tired to care but still want a Mexican casserole that tastes like I tried.

What You Need

You need 1 tablespoon vegetable oil to get the beef started without sticking. Then 1½ pounds ground beef that’s 90/10 or leaner—if you go fattier you’ll have to drain it and that’s annoying. One packet of taco seasoning does all the heavy lifting for spice so you don’t have to measure out cumin and chili powder separately. A small white onion gets diced up and 2 cloves garlic get minced because those two things make the base taste like actual food instead of just seasoned meat.

For liquid you’re using 1½ cups chicken stock and a 14½-ounce can of diced tomatoes with their juice. The stock and tomato liquid together cook the rice. You need 1 cup jasmine rice specifically—it’s what makes this work. A 15-ounce can of black beans goes in after you drain and rinse them. The 4-ounce can of green chiles and 1 teaspoon hot sauce add the right amount of kick without making it spicy enough to scare anyone off.

Corn comes in at 1 cup, either fresh or frozen, and it goes in at the very end so it stays sweet. The 1 cup shredded colby jack cheese melts into everything while it’s still hot off the stove. Optional garnishes are sour cream, scallions, avocado, and cilantro if you want to make it look like you tried harder than you did.

How to Make Mexican Beef Rice Casserole

Heat your vegetable oil in an extra large skillet or cast iron pan over medium heat. Add the ground beef and break it apart with a wooden spoon as it browns. You want to cook it until there’s no pink left and you hear that sizzling sound when the liquid releases. If your beef is fattier than 90/10 you’ll need to drain the grease now but hopefully you bought the right kind.

Stir in the taco seasoning, diced onion and minced garlic all at once. The onions will start softening and you’ll smell the spices blooming after about 2 minutes. Keep stirring so nothing gets too dark on the bottom. This is when the kitchen starts to smell like a Mexican casserole instead of just plain beef.

Pour in the chicken stock first, then add the jasmine rice, black beans, diced tomatoes with all their juice, green chiles and hot sauce. Stir everything really well so the rice gets coated and nothing’s sitting in clumps. The rice needs to be completely mixed in or it’ll cook unevenly.

Cover the pan tight and turn the heat down to keep a gentle simmer going. You’ll hear steam hissing and the rice will start swelling over 15 to 20 minutes. Halfway through, lift the lid and stir everything to scrape up any rice that’s sticking to the bottom—this happens with jasmine rice more than long grain but it’s fine, just don’t let it sit there.

Taste the rice near the end to check if it’s soft but still has some bite to it. When it’s there, stir in the corn kernels. Cook uncovered for another 2 minutes until the corn heats through and looks bright. The corn hitting that hot beef rice skillet wakes up the whole dish.

Pull it off the heat and sprinkle the colby jack cheese over the top right away. Toss it well so the cheese melts into creamy ribbons from the residual heat. If you wait too long the pan cools down and the cheese just sits there in shreds instead of melting through. Serve it hot with sour cream, scallions, avocado chunks or cilantro if you want.

What I Did Wrong the First Time

I didn’t stir halfway through the rice cooking and a layer of jasmine rice welded itself to the bottom of my cast iron. It wasn’t burned exactly but it was stuck enough that I had to soak the pan for an hour. The rice on top was fine but I lost a good half cup to the bottom layer. Now I set a timer for 8 minutes and go in with a spatula to scrape everything loose. It takes 10 seconds and saves me from scrubbing later which is the whole point of an easy beef dinner in one pan.

Ingredients

• 1 tablespoon vegetable oil
• 1½ pounds ground beef, 90/10 or leaner
• 1 packet taco seasoning
• 1 small white onion, diced
• 2 cloves garlic, minced
• 1 ½ cups chicken stock
• 1 cup jasmine rice
• 1 (15-ounce) can black beans, drained and rinsed
• 1 (14 ½-ounce) can diced tomatoes with juice
• 1 (4-ounce) can green chiles
• 1 teaspoon hot sauce
• 1 cup corn kernels, fresh or frozen
• 1 cup colby jack cheese, shredded
• Optional garnishes: sour cream, scallions, avocado, cilantro

Method

1. 1 Heat the vegetable oil in an extra large skillet or cast iron pan over medium heat. Add ground beef, breaking it apart as it browns. Cook until no pink remains and liquid releases sizzling sounds. If beef is fattier than 90/10, drain excess grease now.
2. 2 Stir in taco seasoning, diced white onion, and minced garlic. Listen for the onions softening and the aroma of spices blooming over about 2 minutes, stirring often so nothing fries too dark.
3. 3 Pour in chicken stock followed by jasmine rice, black beans, diced tomatoes with their juice, green chiles, and hot sauce. Stir everything thoroughly so rice is evenly coated and mixture is uniform.
4. 4 Cover the pan tightly, lowering heat to maintain a gentle simmer. Let cook for 15 to 20 minutes; steam hiss rising, rice grains swelling. Halfway through, lift the lid and stir to scrape up any rice clinging to the bottom.
5. 5 Check rice tenderness by tasting near the end. When it’s soft but still has bite, stir in the corn kernels. Cook uncovered for another 2 minutes until the corn is heated through and bright.
6. 6 Remove from heat and immediately sprinkle colby jack cheese over the casserole. Toss well so the residual warmth melts the cheese into creamy ribbons.
7. 7 Serve piping hot, topped with optional sour cream, sliced scallions, ripe avocado chunks, and fresh cilantro if desired.

Tips for the Best Mexican Beef Rice Casserole

Use a skillet that’s at least 12 inches wide or you’ll have rice piled too high and it won’t cook evenly. The rice needs surface area to spread out and absorb liquid without steaming itself into a gummy mess.

Don’t skip rinsing the black beans or you’ll end up with a grayish foam floating on top while everything simmers. Takes 30 seconds under cold water and the difference is obvious.

If your jasmine rice is older than six months it might need an extra splash of stock because it dries out in the bag over time. I added maybe two tablespoons more when I noticed the liquid was gone but the rice still had a chalky center.

The cheese melts better if you turn off the heat completely and let the pan sit for a minute before tossing. Residual heat does the work without making the cheese greasy or separated.

When you’re stirring halfway through, if you see the rice starting to stick in one spot, rotate the pan on the burner because your stove probably has a hot spot you didn’t know about. Mine does and now I just turn the whole thing 180 degrees at the eight-minute mark.

Serving Ideas

I put this Mexican casserole in bowls instead of on plates because it holds together better with sides. Tortilla chips on the side for scooping work better than trying to serve it with a spoon that just breaks everything apart.

A quick lime crema is just sour cream with lime juice stirred in and it cuts through the richness without adding more steps. Pickled jalapeños from a jar add the acid this needs if you’re not doing the lime thing.

Leftover rotisserie chicken shredded over the top the next day turns it into a different meal and stretches it to feed ten instead of eight.

Variations

Ground turkey instead of beef makes this lighter but you have to add a tablespoon of olive oil with the turkey or it’ll stick and dry out. The flavor’s less deep but it works if that’s what you’ve got.

Swap the jasmine rice for brown rice and you’ll need to add another half cup of stock and simmer for 35 minutes instead of 20. I tried it once and the texture was chewier, which I liked but my husband didn’t.

Pepper jack instead of colby jack gives you more heat without adding hot sauce. The peppers in the cheese distribute better than relying on the green chiles alone.

A can of Rotel instead of plain diced tomatoes amps up the spice and adds little tomato chunks with more bite. It’s basically this beef rice skillet’s louder cousin.

FAQ

Can I use long grain white rice instead of jasmine rice?
Yeah but it won’t stick together the same way. Long grain stays separate and loose which is fine for a side dish but this easy beef dinner needs a little cling to hold everything together. You might have to add two extra minutes to the simmer time too.

What if I don’t have taco seasoning?
Use 1 tablespoon chili powder, 1 teaspoon cumin, half a teaspoon each of paprika and garlic powder, and a pinch of cayenne. It’s basically the same thing broken down but you’ll have to measure it yourself.

Can I make this ahead and reheat it?
You can but the rice soaks up more liquid as it sits so it’ll be drier when you reheat. Add a quarter cup of stock or water when you warm it up in the microwave or on the stove and stir it through.

Do I really need to stir halfway through?
If you skip it you’re gambling. Sometimes the rice on the bottom will stick and sometimes it won’t depending on your pan and your stove. I don’t like those odds so I just stir.

Can I freeze this Mexican casserole?
Freezes fine for up to three months in an airtight container. The rice texture changes a tiny bit when you thaw it but it’s not bad, just softer. Thaw it in the fridge overnight and reheat with a splash of stock.

What kind of skillet works best for this?
Cast iron or a heavy stainless steel pan with a tight lid. Nonstick works too but the rice won’t get those slightly crispy bits on the bottom that add texture. If your lid doesn’t fit tight, cover it with foil first then put the lid on.

Can I use fresh tomatoes instead of canned?
You’d need about 2 cups of diced fresh tomatoes but they don’t have enough liquid so you’d have to add another half cup of stock. Canned is easier and honestly tastes better in this because they’re packed at peak ripeness.

What if my rice is still hard after 20 minutes?
Add another quarter cup of stock, cover it again, and give it five more minutes. Your heat might’ve been too low or your rice is old and takes longer to hydrate.

Can I add more vegetables?
Diced bell peppers go in with the onions and they work fine. Zucchini turns to mush so don’t. Pinto beans instead of black beans work but they’re softer so stir gently at the end.

How do I know when the rice is done?
Taste a few grains from the middle of the pan. They should be soft all the way through but still have a little resistance when you bite down. If it’s crunchy in the center it needs more time.

What can I use instead of chicken stock?
Beef stock works and makes the whole thing taste meatier. Vegetable stock is fine but a little flat so add an extra half teaspoon of salt. Water in a pinch but then you’re relying entirely on the taco seasoning for flavor.

Why does my cheese clump instead of melting?
The pan cooled down too much before you added it. Next time pull it off the heat, count to thirty, then add the cheese and toss immediately while it’s still steaming hot.

Can I use a different kind of cheese?
Monterey jack or a Mexican blend both melt the same way. Cheddar works but it’s greasier. Pre-shredded is fine but block cheese you shred yourself melts smoother because it doesn’t have the anti-caking stuff on it.

How do I reheat leftovers without drying them out?
Microwave in 90-second bursts with a damp paper towel over the bowl. On the stovetop, add a few tablespoons of water or stock and heat it covered over low so the steam rehydrates the rice.

What if I don’t have green chiles?
A diced poblano or Anaheim pepper adds the same mild heat. Or just skip them and add an extra half teaspoon of hot sauce at the end if you want.

Can I double this recipe?
Not in one pan unless you’ve got a huge paella pan or something. The rice won’t cook right if it’s piled more than an inch and a half deep. Make two batches or use two skillets side by side.

Is this spicy?
Not really. The green chiles and one teaspoon of hot sauce give it warmth but nothing that’ll scare off kids. If you want actual heat, double the hot sauce or use pepper jack cheese.

What’s the best way to dice an onion for this?
Doesn’t matter as long as the pieces are small enough to soften in two minutes. I do a rough chop into quarter-inch bits and call it done.

Can I use minute rice?
Technically yes but you’d only simmer it for five minutes and it’ll turn mushy fast. Minute rice doesn’t have the structure to hold up in a dish like this where it sits in liquid for a while.
