· 1 teaspoon salt
· ½ teaspoon black pepper
· ½ teaspoon paprika (optional)
Optional Add-Ins:

· ½ cup breadcrumbs mixed with 2 tablespoons melted butter (for crunchy topping)
For Serving:

Step-by-Step Instructions
Step 1: Preheat and Prepare
Preheat your oven to 375 degrees Fahrenheit (190 degrees Celsius). Grease a 9×13-inch baking dish or a 3-quart casserole dish with non-stick spray or butter.
Step 2: Cook the Pasta
Bring a large pot of generously salted water to a boil. Add the egg noodles and cook according to package directions until al dente (about 1 minute less than the package recommends). Drain and set aside.
Step 3: Brown the Ground Beef
Heat a large skillet over medium-high heat. Add the ground beef and cook, breaking it apart with a wooden spoon, until browned and no longer pink, about 5 to 7 minutes. Add the diced onion and cook for 2 to 3 minutes until softened. Add the minced garlic and cook for 30 seconds until fragrant. Remove the beef mixture from the skillet and set aside.
Step 4: Sauté the Mushrooms
In the same skillet, add the sliced mushrooms. Cook over medium heat for 4 to 5 minutes until they release their liquid and start to brown. If the skillet is dry, add a teaspoon of oil or butter.
Step 5: Make the Creamy Sauce
In a large bowl, whisk together the cream of mushroom soup, sour cream, milk (or broth), ½ cup of the shredded cheddar cheese, salt, pepper, and paprika until smooth.
Step 6: Combine Everything
In the large bowl with the sauce, add the cooked ground beef mixture, sautéed mushrooms, and cooked egg noodles. Stir until everything is evenly coated.
Step 7: Transfer to Baking Dish
Pour the mixture into the prepared baking dish, spreading it into an even layer.
Step 8: Add the Topping
Sprinkle the remaining ½ cup of cheddar cheese (and mozzarella, if using) over the top. If using a breadcrumb topping, sprinkle it over the cheese.
Step 9: Bake
Bake uncovered for 20 to 25 minutes, until the casserole is bubbly and the cheese is melted and golden brown. If you want a browner top, broil for the final 1 to 2 minutes, watching carefully.
Step 10: Rest and Serve
Let the casserole rest for 10 minutes before serving. Garnish with fresh parsley. Serve warm.
One-Pot Stovetop Method
Step 1: Brown the Beef and Mushrooms
In a large skillet or Dutch oven, brown the ground beef, onion, garlic, and mushrooms together. Drain excess fat.
Step 2: Add Pasta and Liquid
Add the uncooked egg noodles, cream of mushroom soup, sour cream, milk, salt, pepper, and 1 cup of water or broth. Stir to combine.
Step 3: Simmer
Bring to a simmer, then reduce the heat to low. Cover and cook for 10 to 12 minutes, stirring occasionally, until the pasta is tender.
Step 4: Add Cheese
Stir in 1 cup of shredded cheddar cheese until melted. Serve immediately.
Slow Cooker Method
Step 1: Brown the Beef and Mushrooms
Brown the ground beef, onion, garlic, and mushrooms in a skillet. Drain excess fat.
Step 2: Transfer to Slow Cooker
Transfer the beef mixture to a slow cooker. Add the uncooked egg noodles, cream of mushroom soup, sour cream, milk, salt, pepper, and 1 cup of water or broth. Stir to combine.
Step 3: Slow Cook
Cover and cook on LOW for 2 to 3 hours, until the pasta is tender.
Step 4: Add Cheese
Stir in the shredded cheddar cheese until melted. Serve directly from the slow cooker.
Cooking Tips and Pro Tips for Best Results
· Do not overcook the pasta: Cook the noodles al dente (slightly undercooked) because they will continue to absorb liquid in the casserole.
· Sauté the mushrooms well: Browning the mushrooms intensifies their earthy flavor and removes excess moisture.
· Use full-fat sour cream: Full-fat sour cream provides the best flavor and creaminess. Low-fat may result in a thinner sauce.
· Shred your own cheese: Pre-shredded cheese contains anti-caking agents that prevent smooth melting. Grate cheese from a block for the best results.
· Add vegetables: Peas, carrots, or spinach are excellent additions. Add them to the sauce mixture.
· Make it ahead: Assemble the casserole (without baking), cover, and refrigerate for up to 24 hours. Add 10 to 15 minutes to the baking time.
Variations and Substitutions
· Ground turkey mushroom casserole: Substitute ground turkey for the beef. Add 1 tablespoon of olive oil when browning.
· Vegetarian mushroom casserole: Omit the ground beef and add 2 cups of cooked lentils or extra mushrooms.
· Spicy ground beef casserole: Add ½ teaspoon of red pepper flakes or a diced jalapeño.
· Add bacon: Cook 4 slices of bacon until crisp, crumble, and sprinkle over the top.
· Gluten-free: Use gluten-free pasta and gluten-free cream of mushroom soup.
· Low-carb or keto: Substitute the egg noodles with cauliflower rice or zucchini noodles. Use a low-carb cream soup.
Serving Suggestions
This creamy ground beef and mushroom casserole is a complete meal on its own, but it pairs beautifully with:
· Simple green salad: A crisp salad with a tangy vinaigrette cuts through the richness.
· Roasted vegetables: Green beans, broccoli, or asparagus on the side.
· Crusty bread or dinner rolls: For sopping up any extra sauce.
· Steamed peas or carrots: Adds color and freshness.

Frequently Asked Questions
Can I use a different pasta shape?
Yes. Any short pasta like rotini, penne, shells, or cavatappi works well. Adjust cooking time accordingly.
Can I use fresh mushrooms instead of canned?
Yes. Fresh cremini or button mushrooms are recommended for the best flavor. Sauté them before adding to the casserole.
Can I make this without canned soup?
Yes. Make a from-scratch cream sauce: melt 3 tablespoons of butter, whisk in 3 tablespoons of flour, cook for 1 minute, then slowly whisk in 1½ cups of milk and ½ cup of broth. Simmer until thickened. Stir in ½ cup of sour cream and season with salt, pepper, and garlic powder.
Why is my casserole dry?
Dry casserole usually means there was not enough sauce, or the pasta was overcooked. Use the full amount of sauce ingredients, and cook the noodles al dente.
Can I add vegetables to this casserole?
Absolutely. Peas, carrots, spinach, and broccoli are excellent additions. Add them to the sauce mixture.
Is this recipe gluten-free?
Not as written. Use gluten-free pasta and gluten-free cream of mushroom soup to make it gluten-free.
Can I make this in a slow cooker?
Yes. Brown the beef and mushrooms in a skillet first, then transfer to a slow cooker with the remaining ingredients (use uncooked pasta). Cook on LOW for 2 to 3 hours.
How do I get a crispy cheese topping?
Bake uncovered and, if desired, broil for the final 1 to 2 minutes. Add a breadcrumb topping for extra crunch.
