The results? Utter magic. That creamy, melty layer of cheese, the perfectly seasoned beef, and the tender rice—all baked together in one pan. It’s the kind of meal that feels like a warm hug after a long day.

Honestly, casseroles like this are pure nostalgia for me. Growing up, my mom had a rotation of simple, hearty dinners, and this cheesy ground beef rice casserole was always a favorite. But I’ve tweaked it over the years—adding my own touches, swapping in fresh herbs, and experimenting with different cheeses. I’ve made it more times than I can count, and every time I pull it from the oven, it’s an instant hit, no matter who’s at the table.

This recipe isn’t just about convenience (though, let’s face it, one-pan dinners are lifesavers).

What Ingredients You Will Need

This cheesy ground beef rice casserole brings together a handful of everyday ingredients to create something truly delicious. Here’s what you’ll need:

• Ground beef (1 lb / 450g) – I use lean ground beef for less grease, but regular works fine too.
• Cooked rice (2 cups / 340g, white or brown) – Day-old rice is great if you have it, but freshly cooked is fine.
• Cheddar cheese (2 cups / 200g, shredded) – Sharp cheddar gives maximum flavor. You can mix in Monterey Jack or mozzarella if you like it extra gooey.
• Cream of mushroom soup (1 can / 10.5 oz / 298g) – Adds creaminess and depth. Sub with cream of chicken or homemade white sauce if you prefer.
• Sour cream (1 cup / 240g) – This richens the casserole and adds a nice tang. Greek yogurt is a great substitute.
• Onion (1 medium, finely chopped) – Adds sweetness and flavor. I love yellow or sweet onions here.
• Garlic (2 cloves, minced) – Essential for deep, savory flavor.
• Frozen peas (1 cup / 130g) – Adds color and a bit of sweetness. You could use corn or chopped bell peppers if you want variety.
• Salt & pepper (to taste) – Always taste and adjust!
• Olive oil (1 tbsp / 15ml) – For sautéing the beef and veggies.
• Fresh parsley (optional, for garnish) – Brightens everything up right before serving.

Ingredient Notes:

• If you’re gluten-free, swap the soup for a gluten-free variety or use homemade cream sauce thickened with cornstarch.
• For a lower-carb option, try cauliflower rice instead of regular rice (it’s surprisingly good!).
• Don’t have sour cream? Plain yogurt works just fine and adds a similar creamy texture.
• I like to use Tillamook cheddar for its bold flavor, but any shredded cheese will do (just grate it fresh for best melting).
• You can sneak in extra veggies—think spinach, carrots, or zucchini if you want more color and nutrition.

Rummage through your fridge and pantry; odds are, you already have most of what you need for this cheesy ground beef rice casserole. That’s part of the magic!

Equipment Needed

Nothing fancy required—just solid, everyday kitchen tools:

• Large skillet – For browning the beef and sautéing the onions and garlic. If you don’t have one, a medium saucepan works too.
• Mixing bowl – To stir together the creamy sauce and mix everything before baking.
• 9×13-inch (23x33cm) casserole dish – This size is perfect for spreading the mixture evenly and getting that golden cheese crust. You can use a deep oven-safe pan instead.
• Spatula or wooden spoon – For mixing and serving.
• Aluminum foil – To cover the casserole during baking so the cheese doesn’t get too dark too quickly.
• Cheese grater – Freshly grated cheese melts better, but if you’re in a rush, pre-shredded works.

If you’re short on bakeware, I’ve used a deep ovenproof skillet for smaller batches—works like a charm! For maintenance, a quick soak in warm water helps clean cheesy pans. And honestly, thrift store casserole dishes are just as good as pricey ones. No need to splurge unless you want to!

Preparation Method

1. Preheat your oven to 375°F (190°C). Grease your 9×13-inch (23x33cm) casserole dish lightly with olive oil or nonstick spray.
2. Brown the beef: Place a large skillet over medium heat. Add 1 tbsp (15ml) olive oil, then add 1 lb (450g) ground beef. Break up the beef and cook until it’s no longer pink, about 5-6 minutes. Drain off excess fat if needed.
3. Sauté the veggies: Toss in the chopped onion and minced garlic. Cook for another 2-3 minutes until the onion is soft and fragrant. Your kitchen will smell amazing right about now.
4. Mix the creamy base: In a large bowl, combine 1 can (10.5 oz / 298g) cream of mushroom soup, 1 cup (240g) sour cream, and half of the shredded cheddar cheese (1 cup / 100g). Stir in 2 cups (340g) cooked rice and the cooked beef mixture. Season generously with salt and pepper.
5. Add veggies: Fold in 1 cup (130g) frozen peas. If you’re using other veggies, add them now (chopped bell peppers, spinach, etc.).
6. Transfer and top: Pour the mixture into the prepared casserole dish. Smooth the top with a spatula. Sprinkle remaining 1 cup (100g) cheddar cheese evenly over the surface.
7. Bake covered: Cover the dish with aluminum foil. Bake for 25 minutes to heat everything through and melt the cheese.
8. Finish uncovered: Remove the foil and bake for another 10-15 minutes until the cheese is bubbly and golden brown. (If you like extra crispy edges, broil for 2-3 minutes at the end—watch closely!)
9. Garnish and serve: Let the casserole cool for 5 minutes. Sprinkle with chopped fresh parsley if you want a pop of color. Serve hot, straight from the pan.

Troubleshooting & Tips:

• If the casserole seems dry, add a splash of milk or broth before baking.
• Cheese not melting evenly? Shred it fresh and sprinkle in a thin, even layer.
• Want it spicier? Add diced jalapeños or a pinch of cayenne to the beef mixture.

This method is all about layering flavor and texture, so don’t rush the browning step—those caramelized onions are key!

Cooking Tips & Techniques

Here’s what I’ve learned (sometimes the hard way) making this cheesy ground beef rice casserole:

• Brown the beef well: Don’t just cook it until it’s gray—let it get a bit of color for extra flavor (the “fond” at the bottom amps up the taste).
• Use day-old rice: If you have leftover rice, it holds up better and keeps the casserole from getting mushy.
• Layer cheese: Mixing cheese into the casserole as well as on top guarantees a gooey, melty bite every time.
• Cover, then uncover: Baking covered keeps the moisture in and ensures the rice is tender. Uncovering at the end crisps up the cheese just right.
• Don’t skip seasoning: Taste the filling before baking—it’s easier to adjust now than later.
• Let it rest: After baking, give the casserole 5 minutes to set so slices hold together better.
• Use fresh garlic and onion: Powdered versions work in a pinch, but the flavor from fresh is unbeatable.

One time I forgot to cover the casserole and, wow, the top was crunchy (not the good kind). So, foil is your friend here! If your casserole is too runny, bake a bit longer uncovered. And if you want it extra cheesy, add a handful more on top—the more, the merrier.

For multitasking, prep the rice and chop veggies while the beef browns. Clean up as you go, and you’ll have dinner and a tidy kitchen in no time.

Variations & Adaptations

This cheesy ground beef rice casserole is endlessly flexible! Here’s how you can make it yours:

• Gluten-Free: Use gluten-free cream soup or homemade sauce (just thicken with cornstarch or rice flour).
• Low-Carb: Swap regular rice for cauliflower rice or riced broccoli for a lighter version.
• Different Meats: Sub ground turkey, chicken, or even sausage for the beef—each gives a unique flavor twist.
• Vegetarian: Ditch the beef and use canned lentils or black beans. Add extra veggies for bulk.
• Spicy: Add diced jalapeños, chipotle powder, or pepper jack cheese for a kick.
• Seasonal: In summer, I throw in fresh corn and zucchini; in winter, roasted red peppers and spinach are great.
• Cheese Swap: Try gouda, fontina, or a Mexican blend for totally different flavor vibes.

One of my favorite tweaks: I sometimes mix in a handful of chopped sun-dried tomatoes and swap cheddar for smoked gouda. It’s smoky, tangy, and totally addictive. Don’t be afraid to experiment—this casserole is forgiving and fun to play with.

Serving & Storage Suggestions

This cheesy ground beef rice casserole is best served piping hot, straight from the oven. I like to let it rest for a few minutes so it slices nicely. Garnish with fresh parsley or chives if you want a little color.

• Pairings: Serve alongside a crisp green salad, steamed broccoli, or roasted veggies. A side of garlic bread or dinner rolls is a real treat.
• Beverages: I love it with iced tea, lemonade, or a light red wine (if you’re feeling fancy!).
• Storage: Cool completely, then cover tightly. Store in the fridge for up to 4 days.
• Freezing: Wrap individual portions or the whole casserole in foil and freeze for up to 2 months. Thaw overnight in the fridge before reheating.
• Reheating: Warm in a 350°F (175°C) oven for 20 minutes, covered, or microwave single servings until hot. Add a splash of milk if it seems dry.

The flavors actually deepen overnight, so leftovers are amazing. I’ve even packed it in lunchboxes—cold or reheated, it’s always a hit!
