How this recipe comes together

Step-by-step overview so you know what to expect:

Boil egg noodles to just under al dente so they don’t get mushy in the oven.
Brown lean ground beef with onions for flavor and texture.
Add garlic, tomatoes, seasonings, and simmer briefly to marry flavors.
Stir in sour cream and most of the cheddar for a creamy, cheesy interior.
Transfer to a 9×13 pan, top with remaining cheese, and bake until bubbly.

This quick map keeps the timing predictable: about 15–20 minutes active work and a 20-minute bake.

What you’ll need

12 oz egg noodles (regular size) — cook them al dente.
1 lb lean ground beef (90/10 or 85/15 recommended).
1 small onion, finely chopped.
4 cloves garlic, minced.
2 tsp Italian seasoning.
1 tsp salt (adjust to taste).
1/2 tsp black pepper.
1 (15 oz) can petit diced tomatoes.
1 (15 oz) can tomato sauce.
3/4 cup sour cream (plain) — for creaminess; plain Greek yogurt can substitute.
1 1/2 cups cheddar cheese, shredded and divided (1 cup mixed into the filling, 1/2 cup for topping).

Ingredient notes and swaps:

Ground turkey or Italian sausage can replace beef for a different flavor profile.
For a lighter version, use low-fat sour cream or plain Greek yogurt.
Swap half the cheddar with mozzarella for a stretchier melt.
If you want more veggies, stir in 1 cup of frozen peas or chopped bell pepper when you add the tomatoes. For more inspiration on similar casseroles, see this savory beef and egg noodle casserole.

Preparing Beef Noodle Casserole

Delicious beef noodle casserole served in a baking dish with melted cheese on top.

Preheat the oven to 350°F (175°C).
Boil the egg noodles in salted water, but stop about 3 minutes before the package time so they finish cooking in the oven.
In a large skillet over medium-high heat, brown the ground beef with the chopped onion. Break the meat into small pieces so it cooks evenly.
Stir in the garlic and cook 30–60 seconds until fragrant.
Add the diced tomatoes (with juices), tomato sauce, Italian seasoning, salt, and pepper. Simmer 2–3 minutes to blend flavors.
Remove from heat. Stir in the drained noodles, sour cream, and 1 cup of shredded cheddar until combined.
Transfer to a greased 9×13-inch casserole pan. Sprinkle remaining 1/2 cup cheese over the top.
Bake 20 minutes, until the casserole is hot and cheese is bubbly. Let rest 5 minutes before serving.

Step-by-step instructions

Preheat oven to 350°F.
Bring a large pot of salted water to a boil. Add noodles and cook 3 minutes less than package directions. Drain well.
Heat a large skillet over medium-high. Add ground beef and chopped onion. Cook, stirring, until beef is no longer pink and onion is soft.
Add minced garlic; cook 1 minute until fragrant.
Stir in diced tomatoes, tomato sauce, Italian seasoning, salt, and pepper. Simmer 2–3 minutes.
Remove skillet from heat. Fold in drained noodles, sour cream, and 1 cup cheddar.
Spoon mixture into a greased 9×13-inch baking dish. Top with remaining 1/2 cup cheddar.
Bake 20 minutes until hot and bubbly. Let rest briefly, then serve.

Best ways to enjoy it

Serve with a crisp green salad and a simple vinaigrette to cut richness.
Offer garlic bread or warm rolls for sopping up sauce.
For a Sunday supper, plate with roasted Brussels sprouts or steamed green beans.
For a casual family meal, scoop straight from the dish—this casserole is built for sharing.

Storage and reheating tips

Refrigerate leftovers within 2 hours of baking. Store in an airtight container for 3–4 days.
To reheat: cover the casserole (or individual portions) and warm in a 350°F oven for 15–25 minutes until heated through. Microwaving single portions works—heat on medium power in 1-minute intervals, stirring if possible.
To freeze: cool completely, then freeze in a sealed container for up to 3 months. Thaw overnight in the fridge before reheating. If freezing before baking, assemble and freeze, then bake from frozen at 350°F; add 10–15 minutes to the baking time and cover with foil until hot in the center.
Food safety: ground beef should reach 160°F when cooked. Store leftovers shallowly so they cool evenly.

Helpful cooking tips

Don’t overcook the noodles; slightly underdone noodles prevent a stodgy casserole.
Use a wide skillet so the beef browns quickly and evenly. Drain excess fat if desired before adding tomatoes.
For extra flavor, sauté the onions until a little browned and caramelized.
Stir in a splash of Worcestershire sauce (1 tsp) to deepen umami if you like.
If you need a quick shortcut, use pre-shredded cheese—but freshly shredded melts better.

Creative twists

Veg-forward: add 1 cup chopped spinach and 1 cup mushrooms sautéed with the onion.
Mexican-style: swap Italian seasoning for taco seasoning, use diced green chiles, and top with pepper jack.
Creamier: stir in 4 oz cream cheese with the sour cream for a richer texture.
Crunch top: mix panko with a tablespoon of melted butter and sprinkle on top before baking for texture.
Low-carb: replace egg noodles with spiralized zucchini (squeeze excess moisture) or use cauliflower rice—adjust bake time accordingly.
