Ingredients & Substitutions
To achieve the exact textures and flavors of this mouth-watering home-cooked masterpiece, gather the following ingredients.

Ground Beef: You will need 1 lb (450g) of 80/20 ground beef. The slight fat content ensures a savory, tender bite and forms a beautiful crust when seared in the skillet.
Wide Egg Noodles: Measure out 8 oz (225g) of wide dried egg noodles. These sturdy noodles hold their shape perfectly and peek through the cheese layer beautifully.
Cheddar Cheese: Shred 1 cup (115g) of sharp cheddar cheese right off the block. Freshly grated cheddar melts flawlessly to create that vibrant golden color.
Mozzarella Cheese: Use 1 cup (115g) of low-moisture, whole-milk mozzarella. This is the secret to the gooey, stretchy, bubbly cheese pull.
Green Onions (Scallions): Chop 1/4 cup (25g) of fresh green onions. This crucial garnish adds a bright, crisp bite to cut through the heavy richness of the casserole.
Olive Oil & Aromatics: Use 1 tbsp (15ml) of olive oil to sauté 1 medium diced yellow onion (150g) and 3 minced garlic cloves (15g). These foundational ingredients build the aromatic flavor profile.
Tomato Base & Broth: Combine 15 oz (425g) of crushed tomatoes with 1/2 cup (120ml) of beef broth. This creates the rich, savory sauce that binds the beef and noodles together.
Seasonings: You will need 1 tsp (5g) of kosher salt, 1/2 tsp (2g) of black pepper, and 1 tsp (2g) of dried Italian seasoning. These essential spices elevate the overall savoriness of the meat mixture.
Equipment Needed
- Large Cast-Iron Skillet: A 10-inch or 12-inch heavy skillet is required for searing the beef and baking the dish to bubbling perfection.
- Large Pot: Essential for boiling the wide egg noodles before assembling.
- Cheese Grater: Always grate your own cheese for the best melting texture.
- Wooden Spoon or Spatula: For breaking up the ground beef and mixing the rich sauce.
Step-by-Step Instructions
1. Boil the Wide Egg Noodles
Bring a large pot of generously salted water to a rolling boil. Add the 8 oz (225g) of wide egg noodles and cook them for 1-2 minutes less than the package instructions. You want them slightly firm (al dente) so they don’t turn mushy when baked in the savory sauce.
Drain the noodles well and set them aside. Toss them with a tiny splash of olive oil to prevent sticking if desired.
2. Sear the Savory Ground Beef
Place your heavy cast-iron skillet over medium-high heat and add 1 tbsp (15ml) of olive oil. Once the oil is shimmering and hot, add the diced onion (150g) and cook until softened, about 3-4 minutes.
Add the 1 lb (450g) of ground beef to the skillet. Break it apart with a wooden spoon and let it sear untouched for a minute to develop a flavorful brown crust. Cook until no pink remains, then drain any excess fat.

3. Build the Hearty Sauce
Lower the heat to medium and stir in the 3 minced garlic cloves (15g), cooking for 30 seconds until extremely fragrant. Sprinkle in the 1 tsp (5g) salt, 1/2 tsp (2g) black pepper, and 1 tsp (2g) Italian seasoning.
Pour in the 15 oz (425g) of crushed tomatoes and 1/2 cup (120ml) of beef broth. Stir well, scraping up any browned bits from the bottom of the pan, and let the mixture simmer gently for 5 minutes to thicken.
4. Combine and Top with Cheese
Remove the skillet from the heat. Gently fold the cooked wide egg noodles into the savory ground beef mixture until the pasta is completely coated. Smooth the top with your spoon to create an even layer.
Sprinkle the 1 cup (115g) of shredded cheddar and 1 cup (115g) of shredded mozzarella evenly over the entire skillet. Ensure you have a thick, generous layer of cheese covering the pasta and beef.
5. Bake to Bubbly Perfection
Transfer the heavy cast-iron skillet to an oven preheated to 375°F (190°C). Bake for 10-15 minutes, watching closely. You are looking for a thick, bubbly layer of golden-brown melted cheddar and mozzarella cheeses.
Once you achieve that gooey, cheesy texture, carefully remove the hot skillet from the oven. Let it rest for 5 minutes to allow the sauce to settle before serving.
6. Garnish and Serve
Finish the dish by adding a light sprinkle of freshly chopped green onions (1/4 cup / 25g) scattered across the top. The green onions provide a fresh, visual pop that makes the dish look freshly made and incredibly appetizing.
Serve immediately, scooping deeply to reveal the savory ground beef and egg noodles peeking through the cheese.
Expert Tips for Success
- Grate Your Own Cheese: Pre-shredded cheeses contain anti-caking agents that prevent a smooth melt. Grating your cheddar and mozzarella off the block ensures a gooey, stretchy cheese pull.
- Don’t Overcook the Pasta: Boiling the wide egg noodles just until al dente prevents them from becoming soggy as they absorb the tomato and beef broth in the oven.
- Get a Hard Sear on the Beef: Allowing the ground beef to sit undisturbed in the hot cast-iron skillet for a minute builds a deeply savory, caramelized crust that elevates the flavor.
- Broil for Extra Color: If your cheese is melted but not yet golden-brown, pop the skillet under the broiler for 1-2 minutes. Watch it like a hawk to prevent burning!
Storage & Reheating/Freezing
Store any leftover Cheesy Ground Beef Casserole in an airtight container in the refrigerator for up to 4 days. The flavors actually deepen and improve the next day!
To reheat, place individual portions in the microwave for 1-2 minutes, or reheat the entire skillet in a 350°F (175°C) oven covered with foil until warmed through. To freeze, let the casserole cool completely, transfer to a freezer-safe container, and freeze for up to 3 months. Thaw overnight in the fridge before reheating.
What to Serve With This
To turn this hearty skillet into a complete feast, kick things off with a warm, creamy appetizer like our Baked Spinach Artichoke Dip. The bright, cheesy flavors are an incredible way to start the meal.
For a perfect vegetable pairing that cuts through the richness of the beef, whip up a quick pan of Sauteed Zucchini and Mushrooms. You will also want something to mop up that incredible tomato meat sauce, making Garlic Herb Dutch Oven Bread an absolute must-have on the dinner table.
Finally, end the night on a sweet note. Serve up a gorgeous Strawberry Trifle or a batch of decadent Strawberry Cheesecake Cookies for the ultimate family-friendly dessert.

A cast-iron skillet is highly recommended because it goes seamlessly from stovetop to oven and provides an excellent sear on the beef. However, any large oven-safe skillet or a standard 9×13 baking dish will work.
