This is one of those weeknight casseroles that feels like a warm hug and shows up reliably when you need dinner to be quick, filling, and universally liked. It layers simple pantry staples—ground beef, canned tomatoes and beans, cooked rice—with a tangy, creamy rice layer and plenty of cheddar. The result is an almost effortless bake that feeds a crowd and reheats beautifully.
I test recipes until they behave the same way every time. With this dish, the rhythm is straightforward: brown the beef, simmer the chili mix, fold the dairy into hot rice, layer, and bake. Minimal fuss, maximum comfort. You’ll find tips below to keep it from drying out, ways to make it dairy- or gluten-free, and notes on storing leftovers.
Whether you’re building a weeknight meal plan or bringing something to a potluck, this casserole is forgiving. Read through the steps, round up the few tools you need, and let’s get it in the oven.
Gather These Ingredients
Ingredients
- 1 lb lean ground beef — the protein base; browns quickly and keeps the bake hearty.
- 1 (1.75-oz) packet chili seasoning — brings concentrated chili flavor so you don’t need to measure a dozen spices.
- 1 (8-oz) can tomato sauce — adds saucy body and acidity to the beef layer.
- 1 (15-oz) can chili beans, undrained — provides texture, fiber, and bean-ey flavor; keep the liquid.
- 1 (15-oz) can diced tomatoes, undrained — brightens the beef mixture and adds moisture.
- 3 cups cooked rice — the starch layer; use day-old or recently cooked and slightly cooled rice for best texture.
- 1 cup cottage cheese — gives creaminess and a little tang while keeping the rice layer moist.
- 1 cup sour cream — smooths and binds the rice layer; adds richness.
- 1½ cups shredded cheddar cheese — melts to a bubbly, golden topping and adds savory sharpness.
Chili Sour Cream Rice Bake: Step-by-Step Guide
- Preheat oven to 350°F. Spray a 9×9-inch baking dish with cooking spray and set aside.
- In a large skillet over medium-high heat, brown 1 lb lean ground beef, breaking it up with a spoon, until no pink remains (about 6–8 minutes).
- Drain off excess fat from the skillet and return the beef to the skillet.
- Add 1 (1.75-oz) packet chili seasoning, 1 (8-oz) can tomato sauce, 1 (15-oz) can chili beans (undrained), and 1 (15-oz) can diced tomatoes (undrained) to the beef; stir to combine.
- Bring the mixture to a simmer, reduce heat to medium-low, and cook, stirring occasionally, for 5 minutes.
- While the chili simmers, in a medium bowl stir together 3 cups cooked rice, 1 cup cottage cheese, and 1 cup sour cream until evenly combined.
- Spread the rice mixture in an even layer in the prepared 9×9-inch baking dish.
- Spoon the beef and chili mixture evenly over the rice layer.
- Sprinkle 1½ cups shredded cheddar cheese evenly over the top.
- Bake uncovered for 20–25 minutes, until the casserole is heated through and the cheese is melted and bubbly.
- Let the casserole rest about 5 minutes before serving.
Why It Works Every Time
The formula here is simple and dependable because each component has a clear job. The browned ground beef brings savory depth and Maillard flavor. The canned tomato sauce and diced tomatoes deliver acidity and moisture, and the chili seasoning concentrates the flavor so it’s evenly distributed without a long simmer. Chili beans add both heft and sauce; keeping their liquid prevents the casserole from going dry during baking.
The rice layer (mixed with cottage cheese and sour cream) acts as both binder and moisture reservoir. Cottage cheese adds protein and body while sour cream gives tang and richness that balances the spiced beef. Finally, a good layer of shredded cheddar melts into a cohesive, appealing finish. Bake it just long enough to meld flavors and melt the cheese—the short bake time keeps everything moist.
Dairy-Free/Gluten-Free Swaps
Dairy-free: swap the cottage cheese and sour cream for full-fat plain dairy-free yogurt and a firm silken tofu blended until smooth, or use a commercially available dairy-free sour cream and a cottage-cheese alternative if you prefer. Finish with a dairy-free shredded cheese in the same 1½ cup amount so melting coverage stays consistent.
Gluten-free: this recipe is naturally gluten-free as written, provided your chili seasoning and canned goods are labeled gluten-free. Many chili seasoning mixes contain wheat-based thickeners, so check labels. Use certified gluten-free tomato sauce and canned goods if cross-contamination is a concern.
Equipment at a Glance
Keep the kit minimal to streamline the process.
- Large skillet — for browning the beef and simmering the chili mix.
- 9×9-inch baking dish — the recipe is sized for this; an equivalent square pan will work.
- Mixing bowl and spoon — to combine rice with cottage cheese and sour cream.
- Measuring cups and a can opener — for accurate quantities and opening cans.
- Spatula or large spoon — to spread layers cleanly.
Errors to Dodge
Don’t overload the pan. A 9×9-inch dish is specified so the casserole bakes evenly. If you try to double the recipe in one pan, you’ll end up with undercooked middle or overbrowned edges. Use two pans or a larger, proportionally sized dish.
Drain too aggressively and the bake will be dry; drain not at all and the beef layer may be greasy. The step to drain excess fat after browning the beef is deliberate—enough fat removed to avoid greasiness, but the meat should still carry some flavor into the sauce.
Also, don’t skip the 5-minute rest before serving. That short rest lets the layers settle so the casserole slices hold together instead of sliding apart.
Fresh Seasonal Changes
If you want to add fresh produce, do it in a way that maintains the moisture balance. In summer, a cup of roasted corn or charred bell pepper folded into the beef mixture adds sweetness and texture. In colder months, sautéed onions, diced bell pepper, or a cup of cooked, chopped winter greens (like kale or chard) can be stirred into the meat while it simmers.
Keep additions modest—about 1 cup—so you don’t upset the bake’s liquid-to-starch ratio. If you add watery vegetables (tomato, zucchini), briefly sauté to remove excess moisture before combining with the beef.
What I Learned Testing
I made this casserole several ways to find the most forgiving method. Using canned chili beans undrained was a revelation: the bean liquid contributes flavor and prevents dryness, so resist the temptation to drain them. I also tested different rice textures; freshly cooked, very wet rice made the casserole gummy, while slightly drier, cooled rice produced the best texture. If you have freshly made rice, spread it on a tray for a few minutes to let some steam escape.
One more small thing: the cheese amount matters for covering the surface. Too little cheese leaves exposed rice and beef; 1½ cups gives an even, melty blanket that also helps keep the casserole warm while it rests.
Leftovers & Meal Prep
Store cooled leftovers in an airtight container in the refrigerator for up to 3–4 days. Reheat individual portions in the microwave for 1–2 minutes, or reheat a larger portion covered with foil in a 350°F oven for about 15–20 minutes until warmed through. If the casserole seems dry when reheating, add a spoonful of sour cream or a splash of tomato sauce over the portion before reheating to restore moisture.
For meal prep: make the beef mixture ahead and refrigerate for up to 48 hours. Combine the rice and dairy layer just before assembling and baking to keep textures optimal. You can also assemble the full casserole a day ahead and refrigerate it, then add a few extra minutes of bake time to compensate for the cold dish.
Ask & Learn
If you try this, tell me how you adapted it. Did you add veggies? Use a different cheese? Were you tempted to swap the beef for turkey? I read every comment and like to reply with practical adjustments. Common questions I answer: how to make it spicier (add a pinch of cayenne or hot sauce to the beef while simmering), how to make it milder (reduce or omit the chili seasoning), and how to adjust cook time for a glass or metal dish (metal heats faster—check at 18 minutes).

Notes
You can use any type of cooked rice that you prefer – white, brown, basmati are all good.
I used French’s Chili-O seasoning mix. Any brand of chili seasoning will work fine.
For a gluten-free dish, use a packet of gluten-free chili seasoning. McCormick makes a good one.
Don’t like beans in your chili? You can leave them out.
Feel free to add fresh onions, bell peppers, a can of Rotel diced tomatoes and green chiles, or jalapeńos to the chili mixture.
Can Chili Sour Cream Rice Bake be made in advance? Yes! You can assemble the casserole ahead of time and refrigerate it until you are ready to bake. You may need to add a few minutes to the cooking time if baking this dish straight from the refrigerator.
Can Chili Sour Cream Rice Bake be frozen? Yes! Assemble the casserole and let it cool completely. Cover the dish with plastic wrap and aluminum foil and freeze. When ready to bake, thaw and bake as directed.
