Ingredients You’ll Need

Wide Egg Noodles

Use 12 ounces of uncooked wide egg noodles. Cook them just slightly under al dente because they will continue cooking while the casserole bakes.

Ground Beef

You’ll need 1 pound of ground beef, preferably between 80% and 90% lean. Brown the beef thoroughly and drain the excess grease before combining it with the other ingredients.

Condensed Cream of Mushroom Soup

Use two 10.5-ounce cans of condensed cream of mushroom soup.

For this recipe, the soup should be added directly from the can without diluting it with water or milk. Its thick consistency creates the creamy coating for the noodles and beef.

How to Make 3-Ingredient Beef Noodle Casserole

Step 1: Prepare the Oven and Baking Dish

Preheat the oven to 350°F (175°C).

Lightly grease a 9×13-inch glass baking dish. This helps prevent sticking and allows the edges of the casserole to brown nicely.

Step 2: Cook the Egg Noodles

Bring a large pot of salted water to a boil.

Add the egg noodles and cook them according to the package directions, but stop cooking about 1–2 minutes before they reach al dente.

Drain the noodles thoroughly and set them aside.

The noodles will finish cooking as the casserole bakes, so slightly undercooking them helps prevent them from becoming too soft.

Step 3: Brown the Ground Beef

While the noodles are cooking, heat a large skillet over medium-high heat.

Add the ground beef and break it into small pieces as it cooks. Continue cooking for approximately 6–8 minutes, or until the beef is fully browned and no pink remains.

Drain off excess grease before continuing.

Step 4: Combine the Ingredients

Add the drained egg noodles and browned beef to a large mixing bowl.

Add both cans of condensed cream of mushroom soup.

Do not add water or milk to the soup.

Stir everything together until the noodles and beef are evenly coated with the thick, creamy sauce.

Step 5: Transfer to the Baking Dish

Pour the mixture into the prepared 9×13-inch baking dish.

Spread it evenly from corner to corner. Smooth the surface gently without pressing the mixture down too firmly.

Step 6: Bake

Place the uncovered casserole on the middle rack of the preheated oven.

Bake for approximately 30–35 minutes, or until the edges are bubbling and browned and the top has developed a few lightly golden spots.

The center should be hot and creamy.

Step 7: Let It Rest

Remove the casserole from the oven and allow it to rest for 5–10 minutes before serving.

This brief resting period gives the creamy sauce a chance to thicken slightly, making the casserole easier to scoop while keeping the noodles moist.

Serve warm.

Easy Variations

The basic recipe uses only three ingredients, but there are several simple ways to change it when you want something different.

Use a Different Condensed Soup

If your family isn’t a fan of mushrooms, replace the cream of mushroom soup with cream of chicken or cream of celery.

These alternatives provide a milder flavor and can be a good option for picky eaters.

Add Cheese

For a cheesy version, sprinkle 1–2 cups of shredded cheddar or mozzarella over the casserole during the final 10 minutes of baking.

The cheese will melt over the top and create a gooey, golden finish.

Keep in mind that adding cheese turns the original three-ingredient recipe into a four-ingredient variation.

Make a Larger Batch

To stretch the casserole for a larger group, add an extra handful of cooked noodles.

If the mixture becomes too thick, stir in a small splash of milk before transferring it to the baking dish.

Try Ground Turkey

For a lighter variation, replace some or all of the ground beef with ground turkey.

If you make this substitution, season the meat with salt and pepper while it cooks to add more flavor.

Add a Crunchy Topping

For extra texture, sprinkle crushed crackers or fried onions over the casserole during the final 10 minutes of baking.

These additions provide a crispy contrast to the creamy noodle mixture.

What to Serve With Beef Noodle Casserole

Because this casserole is rich and hearty, simple sides work especially well.

Try serving it with:

• A crisp green salad
• Steamed vegetables
• Roasted green beans
• Corn
• Coleslaw
• Pickles

For a classic comfort-food dinner, add garlic bread, dinner rolls, or buttered toast on the side. The bread is especially good for picking up any extra creamy sauce.

Tips for the Best Beef Noodle Casserole

Don’t Overcook the Noodles

Cook the noodles slightly less than the package instructions recommend. They will continue softening in the oven.

Drain the Beef Well

Removing excess grease keeps the finished casserole from becoming oily.

Don’t Dilute the Soup

The condensed soup should go directly into the mixing bowl. Adding water or milk at this stage can make the casserole too loose.

Give It Time to Rest

The 5–10 minute resting period helps the sauce settle and makes serving easier.

Watch the Edges

The edges should become bubbly and lightly browned while the center remains creamy.

How to Store Leftovers

Allow leftovers to cool before transferring them to an airtight container or covering the baking dish tightly.

Refrigerate for up to 3 days.

When reheating individual portions in the microwave, add a small splash of milk and stir it in before warming. This can help restore some of the casserole’s creamy texture.
