30-Minute Cheesy Ground Beef & Rice Bake

Some nights call for a casserole — the kind with a bubbly cheese top and everybody at the table before it’s cool enough to eat. This cheesy ground beef and rice bake delivers all of that in 30 minutes, and it never touches a separate baking dish. The seasoned beef, tomato sauce, corn, and rice cook together in one oven-safe skillet, then the whole thing goes under the broiler with a blanket of cheddar until it’s golden and bubbling.

Why you’ll love it

• One skillet, casserole payoff. No boiling pasta separately, no layering — the rice cooks right in the seasoned tomato broth.
• A complete meal. Protein, grains, and vegetables in every scoop — no sides required.
• ~32g protein per serving (estimated), from lean ground beef plus a generous cheddar top.
• Kid-approved. Familiar flavors, melty cheese, nothing fussy.

Ingredients

• 1.5 lb ground beef, 90% lean
• 1 tbsp olive oil
• 1 medium yellow onion, diced
• 1 green bell pepper, diced
• 3 cloves garlic, minced
• 2 tbsp tomato paste
• 2 tsp chili powder
• 1 tsp ground cumin
• 1 tsp smoked paprika
• 1 tsp garlic powder
• 1 tsp kosher salt
• 0.5 tsp black pepper
• 1 (15 oz) can tomato sauce
• 1.75 cups low-sodium beef broth
• 1 cup instant white rice, uncooked
• 1 cup frozen corn kernels
• 2 cups shredded sharp cheddar cheese
• 2 green onions, thinly sliced, for serving
• Sour cream, for serving

Equipment

A large oven-safe skillet with a lid (12-inch cast iron or stainless) and a wooden spoon or spatula.

Instructions

1. Brown the beef. Heat the olive oil in a large oven-safe skillet over medium-high heat. Add the ground beef and cook, breaking it into crumbles, until no pink remains, about 7–8 minutes. Drain off excess fat. Meanwhile, position an oven rack 6 inches from the broiler and heat the broiler to high.
2. Soften the vegetables and bloom the spices. Stir in the onion and bell pepper; cook until softened, about 3 minutes. Add the garlic, tomato paste, chili powder, cumin, smoked paprika, garlic powder, salt, and pepper; cook 1 minute more, stirring, until the tomato paste darkens slightly and everything smells fragrant.
3. Add sauce, broth, rice, and corn. Pour in the tomato sauce and beef broth, scraping up any browned bits from the bottom. Stir in the instant rice and the frozen corn. Bring to a lively simmer.
4. Simmer covered. Reduce the heat to medium-low, cover, and cook until the rice is tender and most of the liquid is absorbed, about 10 minutes. Stir once halfway through so nothing sticks.
5. Broil the cheese. Uncover and sprinkle the cheddar evenly over the top. Transfer the skillet to the oven and broil 2–3 minutes, until the cheese is melted, bubbly, and lightly browned in spots. Watch it closely — broilers move fast.
6. Rest and serve. Let the bake rest 3 minutes so the rice finishes absorbing the sauce. Scatter with green onions and serve straight from the skillet with sour cream.

Doneness cues: Ground beef must reach 165°F internally — the long simmer guarantees it well past that. The bake is done when the rice is tender, the mixture looks thick but still a little saucy (it firms up as it rests), and the cheese is bubbling with golden spots.

Nutrition note

Protein is estimated at about 32g per serving, calculated from USDA FoodData Central values for the listed ingredients — this is an estimate, not a lab analysis. Actual values vary by brand and preparation.

Substitutions and tips

• Ground turkey swaps in 1:1 for a leaner bake; add an extra tablespoon of olive oil since turkey is leaner.
• Add beans: stir in a drained 15-oz can of black beans with the corn for extra fiber and protein.
• Pepper jack instead of cheddar gives it a spicy kick the grown-ups will love.
• No oven-safe skillet? Transfer the mixture to a greased 9×13 baking dish before step 5 and broil the same way.
• Don’t walk away from the broiler. Cheese goes from golden to scorched in under a minute — keep the oven light on and watch.

Storage and reheating

Refrigerate leftovers within 2 hours in an airtight container for up to 4 days. Reheat individual portions in the microwave in 60-second bursts, stirring between, or warm the whole skillet covered over medium-low heat with a splash of broth until steaming (165°F). Freezes well for up to 3 months — thaw overnight in the fridge before reheating. The rice softens slightly after freezing but the flavor holds.

Frequently asked questions

Can I use regular long-grain rice instead of instant? Yes, but it changes the timing: use 1 cup long-grain white rice and 2 1/4 cups broth, and simmer covered for 18–20 minutes in step 4 before broiling. Total time becomes about 45 minutes.

Is this good for meal prep? Very — portion into containers and reheat through the week. Pack the sour cream and green onions separately.

Can I make it ahead? Assemble through step 4, cool, and refrigerate up to 24 hours. Reheat covered on the stovetop until steaming, then top with cheese and broil as directed.

How do I keep the rice from getting mushy? Use instant rice as written and don’t over-simmer — 10 minutes covered is enough. The rice keeps absorbing liquid as it rests, so pull it off the heat while it still looks a touch saucy.

Can I add vegetables? Diced zucchini or mushrooms go in with the bell pepper; a handful of baby spinach wilts in right before the cheese. Keep add-ins to about 1 cup so the liquid ratio stays right.
