Cheesy One Pot Hamburger Casserole

Finding a satisfying weeknight dinner that doesn’t leave you with a mountain of dishes can feel impossible. Between getting everyone fed at a reasonable hour and dealing with the cleanup afterward, it’s tempting to just order takeout and call it a day.

That’s exactly why this one pot hamburger casserole has become my saving grace on busy nights. It’s got everything your family wants—ground beef, gooey cheese, and pasta—all cooked together in a single pot, which means less time scrubbing pans and more time relaxing after dinner.

What Kind of Ground Beef Should I Use?

For this one pot hamburger casserole, you’ll want to use ground beef with a fat content that balances flavor and greasiness. I typically go with 80/20 or 85/15 ground beef, which gives you enough fat for good flavor without leaving you with a pool of grease at the bottom of your pot. If you prefer leaner meat like 90/10, that’ll work too, though you might want to add a small drizzle of olive oil to prevent sticking. Just remember that if you do use a fattier blend, you can drain off some of the excess grease after browning the meat and before adding your other ingredients.

Options for Substitutions

This one pot wonder is pretty forgiving when it comes to swaps:

• Ground beef: Ground turkey, chicken, or even plant-based ground meat work great here. Just keep in mind that leaner meats might need a splash of olive oil added to the pan since they won’t release as much fat.
• Cheddar cheese: Feel free to mix things up with Monterey Jack, Colby, or a Mexican cheese blend. You can also use pre-shredded cheese to save time, though block cheese melts a bit smoother.
• Elbow macaroni: Shells, rotini, or penne all work just fine. Stick with similar-sized pasta so the cooking time stays about the same.
• Sour cream: Greek yogurt makes a good substitute if you’re out of sour cream. Plain yogurt works too, though it’s a bit tangier.
• Whole milk: Any milk you have on hand will do – 2%, skim, or even half-and-half if you want it extra creamy.
• Beef broth: Chicken broth or vegetable broth can step in here. The flavor will be slightly different but still tasty.

Watch Out for These Mistakes While Cooking

The biggest mistake with one pot hamburger casserole is not draining the fat after browning the beef, which can leave your dish greasy and unappetizing – take an extra minute to spoon out or drain that excess grease for a much better result.

Another common error is adding the pasta before the broth comes to a proper simmer, which leads to unevenly cooked macaroni with some pieces mushy and others still hard.

When stirring in the sour cream and milk mixture, make sure your heat is on low and the pot isn’t boiling, or the dairy will curdle and separate instead of creating that creamy sauce you’re after.

Finally, resist the urge to skip the covered resting time at the end – those 2-3 minutes allow the cheese to melt perfectly and the sauce to thicken up just right.

What to Serve With Hamburger Casserole?

This one pot hamburger casserole is pretty filling on its own, but I love serving it with a simple side salad to balance out all that cheesy goodness. A basic iceberg or romaine salad with ranch dressing and some cherry tomatoes does the trick perfectly. If you want something warm on the side, steamed green beans or roasted broccoli are great options that won’t leave you feeling too stuffed. For extra comfort food vibes, garlic bread or buttery dinner rolls are perfect for anyone who wants a little something extra to round out the meal.

Storage Instructions

Store: This casserole keeps really well in the fridge for up to 4 days in an airtight container. The flavors actually get even better the next day! Just know that the pasta might soak up some of the sauce as it sits, so you can add a splash of milk or broth when reheating if it seems dry.

Freeze: You can freeze this for up to 3 months, though I’ll be honest – the texture of the pasta and dairy might change a bit. If you want to freeze it, let it cool completely first, then store in a freezer-safe container. It’s best to freeze it before adding the sour cream if you’re planning ahead.

Reheat: Warm it up on the stove over medium-low heat with a little extra milk or broth to loosen it up, stirring occasionally. You can also microwave individual portions for 2-3 minutes, stirring halfway through. Either way, just heat it until it’s warmed through and the cheese gets melty again.

• Calories: 3750-4100

• Fat: 185-210 g
• Carbohydrates: 280-320 g

Ingredients

• 4 cups cheddar cheese (I prefer Tillamook sharp cheddar for better melting)
• 1.25 lb ground beef
• salt
• pepper
• 1 onion (finely diced into 1/4-inch pieces)
• 3 garlic cloves
• 3 tsp Worcestershire sauce (I use Lea & Perrins for the most authentic flavor)
• 2 tbsp tomato paste
• 4 cups beef broth (I recommend Swanson beef broth for a richer base)
• 16 oz elbow macaroni
• 0.75 cup sour cream (makes the sauce extra creamy and rich)
• 0.75 cup whole milk
• 1/2 teaspoon smoked paprika
• parsley

Step 1: Prep and Brown the Beef Base

• 1.25 lb ground beef
• salt
• pepper
• 1 onion, finely diced
• 3 garlic cloves, minced

Dice the onion into 1/4-inch pieces and mince the garlic cloves.

Season the ground beef generously with salt and pepper.

Heat a large pot or Dutch oven over medium-high heat and add the seasoned beef, breaking it apart as it cooks.

Once the beef is browned (about 5-7 minutes), add the diced onion and cook until softened, about 3-4 minutes.

Drain any excess fat if needed, then stir in the minced garlic and cook for 1 minute until fragrant.

Step 2: Build the Flavor Base

• 3 tsp Worcestershire sauce
• 2 tbsp tomato paste
• cooked beef and onion mixture from Step 1

Add the Worcestershire sauce and tomato paste to the browned beef mixture, stirring well to coat everything evenly.

Cook for 1-2 minutes to let the tomato paste caramelize slightly and the Worcestershire sauce integrate into the beef.

This layering of flavors is what gives the casserole its depth—I like to give this step a full minute to really develop the umami-rich base before adding the liquid.

Step 3: Simmer the Pasta

• 4 cups beef broth
• 16 oz elbow macaroni
• flavor base from Step 2

Pour the beef broth into the pot and bring to a simmer, then add the elbow macaroni and stir to combine.

Cover the pot and simmer for 5 minutes, stirring halfway through, then continue cooking covered for another 5 minutes.

The pasta should be nearly tender but still have a slight bite to it—it will finish cooking when the cream is added, so don’t overcook it here.

Step 4: Create the Creamy Cheese Sauce

• 4 cups cheddar cheese
• 0.75 cup sour cream
• 0.75 cup whole milk
• 1/2 teaspoon smoked paprika

While the pasta cooks, shred the cheddar cheese (you should have about 4 cups total).

In a small bowl, whisk together the sour cream and whole milk until smooth.

Once the pasta is nearly tender, reduce the heat to medium-low and slowly pour in the sour cream and milk mixture, stirring constantly to prevent lumps from forming.

Add 2½ cups of the shredded cheese in handfuls, stirring after each addition until fully melted and the sauce is smooth and creamy.

Step 5: Top and Finish

• remaining cheese from Step 4
• fresh parsley for garnish
• creamy pasta mixture from Step 4

Sprinkle the remaining 1½ cups of shredded cheese over the top of the casserole in an even layer.

Cover the pot and cook for 2-3 minutes on medium-low heat just until the cheese on top begins to melt slightly.

Fresh sour cream in the sauce keeps everything wonderfully creamy, but I find that a light sprinkle of smoked paprika adds a subtle smoky note that takes this dish from good to memorable—feel free to add a pinch if you like.

Remove from heat, garnish with fresh parsley, and serve immediately while hot and creamy.
