Easy Spaghetti Casserole with Ground Beef

This easy no-bake spaghetti casserole with ground beef is comfort food at
its finest! The secret to this homestyle pasta dinner with its thick meaty sauce is
a can of mushroom soup!

With large gatherings, it’s nice to have a beef casserole that’s easy and something everyone will like.  Growing up, my mom’s go-to dish was a spaghetti casserole recipe. It was a family favorite, prepared for all family gatherings and is my ultimate comfort food. My husband and in-laws all love it, so the tradition continued until we had children.  

They don’t like spaghetti casserole.  How can that be? If they ate it at a friends house, I bet they would love it! In fact, it’s unusual for me to find any casserole that they’ll eat. Maybe casseroles have just gone out of style, but I just keep serving them. They are perfect for potlucks or when you need to feed a crowd.

I on the other hand, love easy pasta dinner recipes, like Italian sausage pasta, classic lasagna or chicken pasta casserole , or brisket with mac & cheese. There’s just something comforting about a pasta casserole. If you like casseroles, then you’re going to love this recipe.

Mom’s spaghetti, is not Italian in any way. Nothing like a classic Sunday Sauce. There’s no Italian sausage, Parmesan cheese, or even mozzarella cheese. It does have tomato sauce but that’s about it. If you’re looking for a more Italian style baked pasta dish, my favorite is baked penne alla vodka or if you don’t want red sauce, try baked chicken spaghetti.

Not only is this not a traditional Italian based spaghetti, but it’s not baked spaghetti that has cottage cheese or ricotta cheese. It’s a unique recipe that I’ve never had anyplace else.

The base for this spaghetti casserole recipe is cream of mushroom soup and chili con carne.  However, I don’t think they make chili con carne anymore so I use canned chili for the meat sauce. This is about the only recipe I make that has canned mushroom soup. Of course, any casserole that came out of the 70’s had to have mushroom soup in it.

What’s great about this recipe is that it all comes together in one pot. It’s a great freezer meal. You can make it in advance and when you’re ready to eat, heat up the spaghetti mixture and add the top layer of cheese. There’s nothing better than easy meals that are family favorites.

Ingredients you’ll need to make spaghetti casserole with ground beef

• Ground beef – try to go with a leaner beef so that you don’t have as much grease.
• Mushroom soup – while I’m not a big proponent of processed food, this recipe really needs a can of soup.
• Tomatoes and tomato sauce – I’m not a big fan of tomato sauce, so I only use a cup of it. You can definitely add more, my Mom’s has about 2 cups.
• Fresh Mushrooms – you can leave these out, but I like the flavor they add.
• Onions, celery and garlic – it’s where the flavor starts.
• Bay leaf and oregano – classic Italian seasoning.
• Colby cheese – this is what makes it gooey, you can also use cheddar cheese or have a cheese mixture of both.

Pro tip: If you want ooey-gooey cheese, then avoid the pre-packaged cheese. It has a coating that keeps it from melting as much as the block of cheese that you grate.

• Pasta – traditional spaghetti noodles work best because of the thick sauce, you could use bucatini but not thin spaghetti.

Step 1: start with some flavor

Begin by cooking the onions and celery over medium heat then add some garlic.

Step 3: add the pasta

Cook the pasta al dente in a large pot of salted water and add to the spaghetti sauce.

Once combined add cheese to the top and cover until it’s melted. If you are making this in advance, wait to add the cheese until right before serving.
