Classic Ground Beef Casserole Ingredients
Here’s everything you’ll need to make this comforting classic – I’ve measured everything out precisely so your casserole turns out perfect every time:

- 1 lb (450g) ground beef – I prefer 80/20 for the best flavor, but lean works too
- 1 medium onion, diced – about the size of a baseball
- 2 cloves garlic, minced – fresh is best, but ½ tsp garlic powder works in a pinch
- 1 cup (240g) tomato sauce – plain canned works great
- 1 cup (240ml) beef broth – gives that rich depth of flavor
- 1 tsp salt – I use kosher salt
- ½ tsp black pepper – freshly cracked if you’ve got it
- 1 tsp Italian seasoning – my secret flavor booster
- 2 cups cooked pasta – elbows, rotini, or any short pasta you like
- 1 cup shredded cheddar cheese – sharp cheddar adds nice bite
- 1 cup shredded mozzarella cheese – for that perfect melt
- ½ cup sour cream – makes the sauce extra creamy
- 1 tbsp olive oil – for sautéing
- Optional: chopped parsley – for a fresh pop of color
Ingredient Substitutions
Out of something? No worries – here are my favorite swaps:
- Ground beef: Try ground turkey, chicken, or even plant-based crumbles
- Sour cream: Plain Greek yogurt works beautifully
- Cheddar/mozzarella: Any melty cheese blend will do – I’ve used Monterey Jack with great results
- Tomato sauce: Marinara or crushed tomatoes (just reduce slightly)
- Beef broth: Chicken or vegetable broth works in a pinch
See? Cooking should be flexible – make it work with what you’ve got!
How to Make Classic Ground Beef Casserole
Alright, let’s get cooking! This classic ground beef casserole comes together in just a few simple steps – I’ll walk you through each one so yours turns out perfect:

- Preheat your oven to 375°F (190°C) and lightly grease that 9×13-inch baking dish. Trust me, you don’t want to skip this step – nothing’s worse than cheese sticking!
- Sauté the onions in olive oil over medium heat for about 3-4 minutes until they’re nice and soft. That sweet onion flavor is key!
- Brown the ground beef, breaking it apart as it cooks. Here’s my pro tip: drain off most (but not all!) of the grease – we want just enough to keep things flavorful.
- Add the garlic, tomato sauce, beef broth, and seasonings. Let this simmer for about 5 minutes – you’ll smell the magic happening!
- Stir in the sour cream until the sauce turns creamy and dreamy. This is when I usually sneak a taste – chef’s privilege!
- Fold in the cooked pasta gently until every piece is coated in that luscious sauce.
- Transfer to your baking dish and top with all that glorious cheese – I like to mix my cheddar and mozzarella for the perfect melt.
- Bake for 15-18 minutes until the cheese is bubbly and golden. Oh, that smell!
- Let it rest 5 minutes before serving – this helps everything set up nicely.
Tips for the Perfect Classic Ground Beef Casserole
Here are my secret weapons for casserole success:
- Cook pasta al dente – it’ll finish cooking in the oven
- Layer cheeses – half mixed in, half on top for maximum cheesiness
- Use freshly grated cheese – it melts so much better than pre-shredded
- Let it rest! Those 5 minutes make all the difference in texture

Serving Suggestions for Classic Ground Beef Casserole
Oh, let me tell you how I love to serve this casserole – it’s all about keeping things simple but delicious! My absolute must-have is a crusty loaf of garlic bread to scoop up every last bit of that cheesy goodness. For something fresh, a crisp green salad with tangy vinaigrette cuts through the richness perfectly.

When I’m feeling fancy, I’ll roast some broccoli or green beans on the side – the caramelized edges pair beautifully with the creamy casserole. And don’t forget the pickles! A few dill spears on the plate add that perfect zingy contrast. Honestly, this dish plays well with just about anything – even straight from the pan when no one’s looking!
Storing and Reheating Classic Ground Beef Casserole
Here’s the beautiful thing about this casserole – it keeps like a dream! Let it cool completely, then cover tightly with foil or transfer to an airtight container. It’ll stay fresh in the fridge for 3-4 days – though in my house, it never lasts that long!
For freezer storage, wrap individual portions in plastic wrap then foil – they’ll keep beautifully for up to 3 months. When reheating, I always use the oven (350°F for about 20 minutes) to bring back that crispy cheese topping. Microwave works in a pinch, but you’ll lose that perfect texture – though honestly? Still delicious!
Classic Ground Beef Casserole Nutrition Information
Now, I’m no nutritionist, but here’s the deal – this casserole packs protein from the beef, some carbs from the pasta, and all that cheesy goodness. Exact numbers vary based on your ingredients (especially cheese amounts – no judgment here!), but it’s a balanced meal that keeps you full and happy. As with any comfort food, enjoy it as part of a varied diet!
Frequently Asked Questions
Can I freeze this classic ground beef casserole?
Absolutely! This casserole freezes beautifully. Just wrap cooled portions tightly in plastic wrap then foil – they’ll keep for up to 3 months. When ready to eat, thaw overnight in the fridge and reheat at 350°F until bubbly. The cheese might not be quite as melty, but the flavor stays amazing!
What pasta works best?
I’m partial to short pastas like elbows or rotini – they hold the sauce perfectly. But honestly? Any pasta shape you’ve got works here! Just cook it al dente since it’ll soften more in the oven. Pro tip: undercook by 1 minute for perfect texture.
Can I make this ahead?
You bet! Assemble everything (just don’t bake), cover tightly, and refrigerate for up to 24 hours. Add 5-10 minutes to the baking time since it’ll be cold. The flavors actually deepen overnight – one of my favorite make-ahead meals!
Is there a way to lighten this up?
Sure thing! Swap ground turkey for beef, use low-fat cheese, and sub Greek yogurt for sour cream. It’ll still taste delicious – I’ve done all these tweaks when cooking for my health-conscious friends!
