Beef Noodle Casserole Recipe

Make this Beef Noodle Casserole Recipe for a creamy, cheesy weeknight bake everyone will love.

Ingredients

• 1 pound ground beef
• 1 small onion, chopped
• 2 cloves garlic, minced
• 1 can (10.5 oz) cream of mushroom soup
• 1 cup sour cream
• 1/2 cup milk
• 3 cups cooked egg noodles
• 1 cup shredded cheddar cheese
• 1/2 cup grated Parmesan cheese
• Salt and pepper to taste
• 1 tablespoon olive oil
• 1/2 cup crushed crackers or breadcrumbs
• 2 tablespoons melted butter

Instructions

Step 1: Preheat and Sauté Aromatics

Preheat the oven to 350°F (175°C). Warm the olive oil in a skillet and sauté the chopped onion and minced garlic until translucent and fragrant, stirring so the onion becomes soft without browning too quickly. This step builds the savory base—think glossy, softened onion strands and tiny golden garlic flecks perfuming the pan.

Step 2: Brown the Beef and Build the Sauce

Add the ground beef and cook until nicely browned and broken into tender crumbles, then drain any excess fat. Stir in the cream of mushroom soup, sour cream, and milk until the mixture becomes a cohesive, creamy sauce that clings to the beef pieces, then season with salt and pepper to taste. Fold the cooked egg noodles into the beef-sauce until every noodle is coated in the silky, slightly glossy sauce and pockets of creamy mushroom-sour cream cling to noodle curves.

Step 3: Assemble, Top, and Bake

Transfer the noodle-and-beef mixture into a greased 9x13-inch rectangular baking dish, smoothing the surface so noodles and beef are evenly distributed. Evenly sprinkle the shredded cheddar and grated Parmesan over the top, and if using, combine crushed crackers or breadcrumbs with melted butter in a small bowl and scatter that crunchy layer on top. Bake until the casserole is bubbling at the edges and the cheese has formed a golden, slightly caramelized crust—about 25–30 minutes.

Step 4: Rest and Serve

Remove the casserole and let it rest for a few minutes so the sauce settles and the slice holds together. Serve warm straight from the same rectangular dish, the top glittering with browned cheddar, speckled with grated Parmesan and a light scattering of fresh green parsley for contrast.

Notes

• Cook noodles to al dente to prevent a mushy casserole.
• Taste and adjust salt before baking; cheeses add salt.
• Add a splash of milk when reheating if the casserole seems dry.
• For a lighter version, swap ground beef for ground turkey or use less cheese.
• Use fresh grated cheese for better melting and flavor.
