We use our electric roaster to make meals for big groups. Whether it’s a classic side dish of Cheesy Potatoes for 100 at a funeral, making Chicken and Noodles for a men’s shelter or Mac and Cheese for a crowd to feed VBS workers.

Making a really big batch of spaghetti with meat in an electric roaster creates an economical, delicious and filling meal to share with others.

How To Cook Spaghetti For A Crowd

Begin generously coating a 20 quart or larger electric roaster pan with non-stick cooking spray. Take extra care to coat the corners as these are the first places food burns.

Set roaster to 300℉.

Add tomato juice and red pasta sauce.

Tomato juice cover the bottom of an electric roaster.

Then sprinkle the seasonings over the top. Add salt, pepper, dry mustard and garlic powder.

If you want to add Oregano or Italian seasoning this is the best time to do so.

While the sauce is heating up is a good time to brown and drain the ground beef, ground pork or ground turkey.

Since the skillet already has a little residual grease I go ahead and cook the onions in the same skillet until they are tender and translucent.

Cooked ground meat added to seasoned tomato juice in a large black roaster pan.

Cover and cook for an hour and a half (90 minutes). Stir every 30 minutes to keep help the mixture heat evenly and more quickly.

Then add spaghetti.

We like to break the longer sticks of pasta into two or three pieces. This makes stirring, serving and eating easier.

Broken pieces of spaghetti pasta spread over top of a roaster full of red meat sauce.

Stir the pasta into the tomato juice mixture so that no raw spaghetti is visible.

Cover and cook spaghetti in a roaster 45 minutes to an hour longer.

I like to set a timer on 15 minute intervals to remind me to keep stirring often. When the pasta has reached your desired tenderness it is ready to serve.

Serving Instructions

Be sure to have a sturdy spoon that can lift a generous portion onto a plate without bending. A long handle is very helpful to prevent the spoon from falling into the roaster.

Set to keep warm or the lowest heat setting and stir often while serving.

We like to have a can of parmesan cheese handy and House Favorite Garlic Bread to serve with the saucy pasta.

I like to have some extra tomato juice or pasta sauce ready to stir in a cup or two at a time if the baked spaghetti in the roaster begins to dry out.

You can always have some sauce ready in a crock pot and hot water available. This allows pasts to be cooked quickly and stirred into hot meat sauce if you are worried about running out.

Meat Can Be Cooked Ahead of Time

If you want to do some prep work ahead of time the meat and onion can be cooked and refrigerated.

When adding cold, cooked meat to the roaster add 20 minutes to the cook time to allow it to warm up.
