Cheesy Beef and Noodle Casserole

The smell of bubbling cheese and tomato beef sauce always pulls my husband into the kitchen before dinner is even ready. This casserole started as a desperate attempt to use up extra egg noodles and ground beef on a Tuesday, but somehow it became the most requested meal in our house. Now I make double batches just to ensure there are leftovers for lunch the next day.

Last winter my sister came over with her three kids after a chaotic day of errands. I threw this casserole together and watched even the pickiest eater go back for seconds. There is something about noodles baked in beef and cheese that just makes people feel safe and happy.

Ingredients

• 1 lb (450 g) ground beef: The foundation that gives this casserole its hearty satisfying base and rich protein
• 1 medium yellow onion, diced: Sweetness that melts into the sauce and balances the beef
• 2 cloves garlic, minced: Fresh garlic makes all the difference so do not skip it
• 1 cup (150 g) frozen peas: Optional but adds pops of sweetness and color that everyone notices
• 1/2 cup (80 g) diced red bell pepper: Another optional addition that brings subtle sweetness and vibrant color
• 12 oz (340 g) egg noodles: Their wide surface area holds onto sauce beautifully and stands up to baking
• 2 cups (200 g) shredded cheddar cheese, divided: Sharp cheddar gives the best flavor contrast to the creamy base
• 1 cup (240 ml) sour cream: Tang and creaminess that makes the sauce feel luxurious
• 1 can (14 oz / 400 g) diced tomatoes, drained: Fresh tomato flavor and texture without making the casserole too wet
• 1 can (10.5 oz / 295 g) condensed cream of mushroom soup: The secret ingredient that creates that velvety texture we all love
• 2 tbsp tomato paste: Concentrated tomato flavor that deepens the entire beef mixture
• 1 tsp dried Italian herbs: Oregano basil and thyme bring classic Italian American comfort
• 1/2 tsp paprika: Subtle smokiness that rounds out the beef flavor
• Salt and black pepper, to taste: Essential for bringing all the flavors together
• 2 tbsp olive oil: For sautéing the vegetables and preventing sticking

Brown the ground beef:

Add the beef to the skillet breaking it up with a spatula and cook until no pink remains then drain the excess fat.

Build the flavor base:

Create the creamy sauce:

Assemble the casserole:

My friend Sarah told me she makes this for Sunday meal prep and her family actually looks forward to leftovers all week. That is when I knew this recipe was not just good but the kind of good that makes life easier.

Make It Your Own

Swap half the cheddar for mozzarella to get those gorgeous cheese pulls when you scoop a serving. Sometimes I add a cup of frozen corn or diced zucchini depending on what is in my freezer.

Serving Suggestions

A crisp green salad with vinaigrette cuts through the richness beautifully. Steamed green beans with a squeeze of lemon also work wonderfully as a fresh side.
