Ingredients

12 oz (340 g) egg noodles
1 ½ cups sour cream (full‑fat)
1 cup shredded sharp cheddar cheese
½ cup shredded mozzarella cheese
1 medium onion, finely diced
2 cloves garlic, minced
1 ½ cups beef broth
2 tablespoons tomato paste
1 teaspoon Worcestershire sauce
1 teaspoon dried thyme
½ teaspoon smoked paprika
Salt and freshly ground black pepper, to taste
2 tablespoons olive oil
2 tablespoons butter
Fresh parsley, chopped (optional, for garnish)

How to Make Beef Sour Cream Noodle Casserole

Preheat & Prepare: Preheat your oven to 375°F (190°C). Lightly grease a 9‑x‑13‑inch baking dish with a bit of butter.
Cook the noodles: Bring a large pot of salted water to a boil. Add the egg noodles and cook 2 minutes less than the package directs (they’ll finish in the oven). Drain and set aside.
Sauté aromatics: In a large skillet, heat olive oil over medium heat. Add the diced onion and cook 4‑5 minutes until translucent. Stir in the minced garlic and cook another 30 seconds.
Brown the beef: Push the onions to the side, add the ground beef, breaking it up with a spoon. Season with salt, pepper, thyme, and smoked paprika. Cook until the beef is no longer pink, about 6‑7 minutes. Drain excess fat if needed.
Build the sauce: Stir in tomato paste and Worcestershire sauce; cook 1 minute to caramelize. Pour in the beef broth, scraping the bottom of the pan to release browned bits. Bring to a simmer and let it reduce slightly, about 3 minutes.
Combine with sour cream: Reduce heat to low and whisk in the sour cream until smooth. Taste and adjust seasoning with more salt or pepper if desired.
Mix everything together: In a large bowl, combine the cooked noodles, beef‑sour‑cream sauce, half of the cheddar, and half of the mozzarella. Toss gently to coat evenly.
Transfer to the dish: Spoon the mixture into the prepared baking dish, spreading it into an even layer. Sprinkle the remaining cheddar and mozzarella over the top.
Bake: Place the casserole in the oven and bake for 20‑25 minutes, until the cheese is melted, bubbly, and lightly golden.
Rest & serve: Remove from the oven and let it rest 5 minutes. Garnish with chopped parsley if you like, then serve hot.

Tips for Best Results

Don’t overcook the noodles: They should be al dente before the bake; otherwise the casserole can become mushy.
Use full‑fat sour cream: It creates a richer, silkier sauce and prevents curdling.
Brown the beef well: The caramelized bits add depth to the flavor.
Cover for the first 15 minutes: If you notice the top browning too fast, loosely cover with foil, then uncover for the final 5 minutes.
Freeze in portions: Cool the casserole completely, then cut into squares, wrap tightly, and freeze for up to 3 months.

Variations

Cheesy pepper jack twist: Swap half of the cheddar for pepper jack for a mild kick.
Mushroom addition: Sauté 1 cup sliced mushrooms with the onions for an earthy note.
Spicy version: Add ½ teaspoon cayenne pepper or a dash of hot sauce to the sauce.
Gluten‑free: Use gluten‑free egg noodles or substitute with rice pasta.

Storage

Transfer leftovers to an airtight container. Refrigerate for up to 4 days. To reheat, place a portion in a microwave‑safe dish, cover loosely, and heat on high for 2‑3 minutes, stirring halfway. For oven reheating, preheat to 350°F (175°C), cover with foil, and bake 15‑20 minutes until heated through.
