Ingredients You’ll Need

This ground beef casserole relies on pantry staples and familiar flavors, making it ideal for busy weeknights when time is short and tummies are rumbling.

Here’s what you’ll need:

• 1 pound ground beef – Choose 85/15 for a balance of flavor and leanness. You want some fat to carry the flavor, but not so much that it turns greasy.
• 2 (15-ounce) cans tomato sauce – Regular tomato sauce works best here—no need for the pre-seasoned kind. The flavor comes from what you add to it.
• 1 teaspoon white sugar (optional) – Just a touch helps cut the acidity in the tomato sauce. It’s subtle, but Grandma swore by it.
• 1 teaspoon garlic salt – You can use regular garlic powder and salt separately if needed.
• 1 teaspoon salt – Taste and adjust based on your preferences.
• 8 ounces egg noodles – Wide egg noodles are perfect for soaking up the sauce and holding their shape.
• 1 cup sour cream – Adds creaminess and a slight tang to balance the tomato base.
• 3 ounces cream cheese, softened – Brings richness and that irresistible creamy texture.
• 1 large white onion, finely diced – Adds sweetness and depth. Sautéed onion gives this dish that “from scratch” taste.
• ½ cup shredded sharp Cheddar cheese – Sharp cheddar adds boldness and melts like a dream.

🧀 Cheese Tip: Freshly grated cheddar melts smoother than pre-shredded and gives your casserole that golden, bubbly finish we all love. If you want to get fancy, try a mix of sharp cheddar and mozzarella for a gooey pull that’s Insta-worthy.

How to Make Grandma’s Ground Beef Casserole

Here’s how to bring this ground beef casserole recipe to life without breaking a sweat or dirtying every dish in your kitchen. It’s designed to be easy, satisfying, and forgiving (perfect if you’re cooking with “help” from little hands).

1. Preheat Your Oven

Set your oven to 350°F (175°C). This ensures your casserole starts cooking right away and the cheese melts evenly. Nobody wants lukewarm cheese.

2. Boil the Noodles

Cook your egg noodles until just al dente—about 7 to 9 minutes. Remember, they’ll continue cooking in the oven, so a little bite is perfect. Drain and rinse briefly with cool water to stop the cooking process.

3. Cook the Ground Beef

In a large skillet, brown your ground beef over medium-high heat. Add the diced onion and sauté for another 2–3 minutes until it becomes translucent and fragrant. Drain off any excess grease to avoid a soggy casserole.

💡 Optional twist: Add a pinch of Italian seasoning or a splash of Worcestershire sauce to the meat for extra savory depth.

4. Stir in the Sauce

To your skillet, add the tomato sauce, garlic salt, regular salt, and sugar (if using). Let the mixture simmer on low for 15–20 minutes. This gives everything a chance to mingle and thicken up just a bit.

5. Mix the Creamy Layer

In a medium bowl, combine the sour cream, softened cream cheese, and some of the finely diced onion (reserve a little for garnish if you like). Mix until smooth. This is the secret layer that gives the casserole that velvety, rich bite.

6. Assemble It All

Grab your greased 9×13-inch baking dish. Now comes the fun part:

1. Spread half the noodles across the bottom.
2. Top with half the creamy mixture.
3. Layer on half the beef and tomato sauce mixture.

Repeat all layers again: noodles, creamy mix, beef sauce.

7. Add the Cheese

Top it all off with your shredded cheddar cheese. You can even add a pinch of paprika or cracked black pepper for color and flavor.

8. Bake

Bake uncovered for 25–30 minutes or until the cheese is melted and golden brown and the edges are bubbling. Let it rest for 5–10 minutes before serving—it’ll hold together better and won’t burn your tongue.

Ground Beef Casserole Variations & Substitutions

This dish is wonderfully flexible. Here’s how you can make it your own:

🥦 Add veggies – Stir in sautéed mushrooms, chopped spinach, shredded carrots, or bell peppers with the beef mixture. Great way to sneak in greens!

🧀 Switch cheeses – Try Monterey Jack, Colby, mozzarella, or a Mexican blend. Each brings its own flavor and texture.

🍝 Change the pasta – Penne, rotini, shells, or even gluten-free options work just fine. The key is to use something that holds up well when baked.

🦃 Use another protein – Ground turkey, chicken, or even lentils for a meatless take. Just add a splash of olive oil if using leaner meat so it stays moist.

Storage, Freezing & Reheating Tips

This ground beef casserole is practically begging to be doubled and saved for later. Here’s how to make the most of it:

🕒 Make-Ahead: Assemble the casserole, cover tightly with foil or plastic wrap, and store in the fridge for up to 24 hours. Add an extra 10 minutes to the bake time if cold.

❄️ Freezer-Friendly: Freeze it unbaked or baked. If unbaked, freeze tightly wrapped for up to 3 months. Thaw overnight in the fridge before baking. If it’s already baked, wrap individual portions and reheat when needed.

🔥 Reheating Leftovers: Microwave a single serving with a splash of water or extra sauce, covered with a damp paper towel. Or reheat in the oven at 350°F for 15–20 minutes until hot.

A Family Classic with a Side of Nostalgia

Some meals just bring you home. I still remember the first time my daughter helped me assemble this ground beef casserole—layering noodles like it was a craft project. We laughed, made a mess, and added way too much cheese. (But is there really such a thing?)

Now it’s a go-to freezer meal and the dish I bring when someone needs comfort—whether it’s a new baby, a rough week, or just because. It’s not just food. It’s a hug baked in a pan.

FAQ: Ground Beef Casserole Questions Answered

Can I use ground turkey instead of beef?
Yes! Just add a tablespoon of olive oil since turkey is leaner and may need a bit of help in the moisture department.

Can I skip the cream cheese?
Absolutely. Use more sour cream or substitute with plain Greek yogurt or even ricotta. The texture may change slightly but will still be creamy and delicious.

How do I prevent it from drying out when reheating?
Cover it with foil or a microwave-safe lid and add a splash of water, sauce, or even broth before reheating. This helps the noodles and beef stay moist.

What side dishes go well with it?

• Garlic bread
• A crisp green salad with vinaigrette
• Roasted green beans or broccoli
• Steamed carrots with butter and herbs
