Key Ingredients for Comforting Flavor

This casserole comes together with a short list of simple ingredients.

For the Casserole:

• 1 lb Ground Beef (85% lean is ideal)
• 8 oz Egg Noodles
• 1 (10.5 oz) can Cream of Mushroom Soup (condensed)
• 1 cup Sour Cream
• 1 cup Shredded Cheddar Cheese, divided
• 1 small Onion, chopped
• 1 tsp Garlic Powder
• Salt & Black Pepper, to taste

Step-by-Step Instructions

Follow these simple steps for a perfectly baked, creamy casserole.

Step 1: Cook the Noodles & Beef

Preheat your oven to 350°F (175°C). Cook the egg noodles according to package directions until al dente, then drain. In a large skillet over medium heat, cook the ground beef and chopped onion until the beef is browned and the onion is soft. Drain any excess grease.

Step 2: Make the Creamy Sauce

Reduce the heat to low. To the skillet with the beef, add the cream of mushroom soup, sour cream, garlic powder, salt, and pepper. Stir until everything is warm and well combined into a creamy sauce.

Step 3: Combine & Assemble

Add the drained cooked noodles to the skillet and stir gently until all the noodles are coated in the sauce. Transfer the entire mixture to a greased 9×13 inch baking dish. Sprinkle the shredded cheddar cheese evenly over the top.

Step 4: Bake Until Bubbly

Bake, uncovered, for 25-30 minutes, or until the cheese is completely melted and the edges are lightly bubbly. Let the casserole stand for 5-10 minutes before serving to allow it to set slightly.

Expert Tips for the Best Results

• Prevent Mushy Noodles: Cook your noodles to al dente (firm to the bite), as they will continue to soften while baking in the sauce.
• Boost the Flavor: For a deeper flavor, add 1 tsp of Worcestershire sauce or ½ tsp of smoked paprika to the beef while browning. You can also use a can of Cream of Celery or Onion soup for a different flavor profile.
• Add Veggies Easily: Stir in 1 cup of frozen peas, corn, or mixed vegetables or ½ cup of diced bell peppers or mushrooms when you combine the sauce and noodles.
• Make-Ahead & Freeze: Assemble the casserole (unbaked), cover tightly, and refrigerate for up to 24 hours. Bake as directed, adding 5-10 extra minutes. To freeze, assemble in a freezer-safe dish, wrap well, and freeze for up to 2 months. Thaw in the fridge overnight before baking.
• Creamy Sauce Secret: For an extra rich and creamy sauce, stir ½ cup of the shredded cheese into the beef and sauce mixture before adding the noodles, then use the remaining cheese for the top.

Frequently Asked Questions (FAQs)

Can I use a different kind of pasta?
Absolutely. While egg noodles are traditional, you can use any short pasta that holds sauce well, like rotini, penne, or bow-tie (farfalle) pasta. Cook it to al dente as directed.

How do I store and reheat leftovers?
Store cooled leftovers in an airtight container in the refrigerator for 3-4 days. Reheat individual portions in the microwave, or reheat the whole dish covered with foil in a 350°F oven for 15-20 minutes until heated through.

What can I substitute for cream of mushroom soup?
You can use cream of celery, cream of chicken, or a homemade “cream of” soup substitute. To make a quick substitute, mix 1 cup of milk with 2 tbsp of flour and 2 tbsp of butter, cook until thickened, and season with salt and a pinch of onion powder.

Can I make this casserole gluten-free?
Yes! Use gluten-free egg noodles and ensure your cream of mushroom soup (or substitute) is certified gluten-free. The rest of the ingredients are naturally gluten-free.

My casserole seems dry. How can I fix it?
If the casserole seems dry after baking, it may have been overbaked or the noodles absorbed too much liquid. Next time, try adding ¼ cup of beef broth or milk to the sauce mixture before baking. For this batch, you can stir a little warmed broth into individual servings.
