Cheesy Beef and Noodle Casserole

The first time I made this casserole, I was trying to use up random ingredients from my fridge before grocery day. My husband took one bite and asked if I could add it to our regular rotation immediately. Now it is the dish my kids actually request when they have friends over for dinner.

I remember bringing this to a neighborhood potluck when we first moved to our street. Three different neighbors asked for the recipe, and one of them became my closest friend. Food has a way of starting conversations that nothing else can.

Ingredients

• 1 lb (450 g) ground beef: The foundation of this hearty casserole, choose 85% lean for the best balance of flavor and moisture
• 1 medium yellow onion, diced: Sweet and aromatic when cooked down, this builds the savory base
• 2 cloves garlic, minced: Fresh garlic makes all the difference here, add it right before the beef finishes cooking
• 1 cup (150 g) frozen peas (optional): These add little pops of sweetness and color that kids actually eat
• 1/2 cup (80 g) diced red bell pepper (optional): A secret way to sneak in extra vegetables without anyone complaining
• 12 oz (340 g) egg noodles: Wide egg noodles hold onto the sauce beautifully and stay tender even after baking
• 2 cups (200 g) shredded cheddar cheese, divided: Sharp cheddar gives the best flavor punch, but medium works if that is what you have
• 1 cup (240 ml) sour cream: This creates the creamy, tangy element that makes the sauce so comforting
• 1 can (14 oz / 400 g) diced tomatoes, drained: Drain them well so your casserole does not become watery
• 1 can (10.5 oz / 295 g) condensed cream of mushroom soup: The shortcut that binds everything together into that perfect casserole consistency
• 2 tbsp tomato paste: Concentrated tomato flavor that deepens the whole dish
• 1 tsp dried Italian herbs: Oregano, basil, and thyme bring that classic Italian-American comfort food vibe
• 1/2 tsp paprika: Just enough to add a subtle warmth and beautiful color
• Salt and black pepper, to taste: Taste as you go, especially if using salted butter or canned soup
• 2 tbsp olive oil: For sautéing the vegetables and preventing everything from sticking

Instructions

Get your oven ready:

Preheat to 375°F (190°C) and give a 9x13 inch baking dish a quick coat of cooking spray or butter

Boil the noodles:

Cook egg noodles according to the package but pull them a minute early since they will cook more in the oven, then drain well

Sauté the vegetables:

Heat olive oil in a large skillet over medium heat and cook the onions and red bell pepper for 3 to 4 minutes until they soften and smell amazing

Brown the beef:

Add the ground beef and break it apart with your spatula as it cooks, then drain off any excess fat before moving on

Build the flavor:

Stir in the garlic for just 1 minute, then add the tomato paste, drained tomatoes, peas, Italian herbs, paprika, salt, and pepper, letting everything cook together for 3 to 4 minutes

Make it creamy:

Remove the skillet from the heat completely before folding in the sour cream and cream of mushroom soup until no white streaks remain

Combine everything:

Gently fold in half the shredded cheese and all the cooked noodles, being careful not to break up the noodles too much

Assemble the casserole:

Spread the mixture evenly in your prepared baking dish and cover the top with the remaining shredded cheese

Bake until bubbly:

Slide it into the oven for 25 to 30 minutes until the cheese is golden and the sauce is bubbling up around the edges

Let it rest:

Wait 5 minutes before serving so the casserole sets slightly and makes serving much easier

Save to Pinterest

This recipe saved me more than once during those chaotic toddler years when getting dinner on the table felt like an Olympic sport. Now that the kids are older, they still get excited when they smell it baking, which feels like a small victory.

Make It Your Own

I have learned that casserooles are incredibly forgiving once you understand the basic formula. Sometimes I swap in ground turkey or add extra vegetables depending on what needs using up. The beauty is in the versatility.

Serving Suggestions

A crisp green salad with vinaigrette cuts through the richness perfectly. Steamed green beans or roasted broccoli also work beautifully alongside. Keep the sides simple since the casserole is so satisfying on its own.

Storage And Leftovers

This actually tastes better the next day as the flavors have more time to meld together. Store covered in the refrigerator for up to 4 days or freeze individual portions for those nights when cooking feels impossible.

• Reheat covered with foil at 350°F until heated through
• Add a splash of milk before reheating if it seems dry
• Freeze for up to 3 months in freezer-safe containers

There is something so deeply satisfying about a bubbling casserole coming out of the oven. I hope this becomes one of those recipes your family asks for again and again.

Recipe Questions & Answers

→ Can I make this casserole ahead of time?

Yes, assemble the entire dish up to 24 hours in advance, cover tightly, and refrigerate. When ready to bake, you may need to add 5–10 minutes to the cooking time if baking cold from the refrigerator.

→ What other pasta shapes work well?

While egg noodles are traditional, you can substitute rotini, penne, macaroni, or cavatappi. Adjust cooking time according to package directions to ensure pasta stays al dente.

→ Can I freeze leftovers?

Portion cooled leftovers into airtight containers and freeze for up to 3 months. Thaw overnight in the refrigerator and reheat in a 350°F oven until warmed through, about 20–25 minutes.

→ How can I make it spicier?

Add crushed red pepper flakes, diced jalapeños, or a splash of hot sauce to the beef mixture. You can also use pepper jack cheese in place of half the cheddar.

→ What vegetables can I add?

Spinach, mushrooms, zucchini, corn, or broccoli florets work well. Sauté heartier vegetables like mushrooms and zucchini with the onions so they cook through properly.

→ Can I use fresh tomatoes instead of canned?

Yes, use about 2 cups diced fresh tomatoes. You may need to cook the mixture slightly longer to evaporate excess moisture before combining with the noodles.
