There are a few foods that I specifically remember my dad making me when I was young. His peanut butter, mayo and raisin sandwiches, grilled chicken, and spaghetti casserole. He always said it was his dad’s recipe, which cracked me up because neither one of them ever measured anything or wrote it down. Finally I convinced my dad to walk me through the process so I could take notes and actually make it a real recipe.

This is not healthy. This is good ‘ole fashioned comfort food. It’s the cheat meal to end all cheat meals. It will likely clog your arteries and do bad things to your cholesterol but believe me it will be worth it.

This recipe will make at least 12-15 servings. It’s great for feeding a crowd at a potluck, but it also makes excellent leftovers if you’re feeding a small family! If need be, the recipe can be easily halved and made in a smaller casserole dish.

Ingredients for spaghetti casserole. Ground chuck, sharp cheddar cheese, spices, mushrooms, spaghetti noodles, onion, ketchup, ritz crackers, tomato sauce, cream of mushroom soup, red wine vinegar, Worcestershire

How Do I Make Spaghetti Casserole?

Begin by heating an oiled skillet over medium heat. Add the ground chuck, chopped mushrooms, and diced onion. We use 80% lean ground chuck. You can use a leaner meat but the fat adds so much to the flavor and tenderness of the meat, I personally feel that it’s worth it. As the meat cooks, use a spatula to break it up into small pieces. Cook until the meat begins to brown and the onions start to turn translucent.

In a separate bowl whisk together the garlic powder, oregano, chili powder, Worcestershire sauce, red wine vinegar, ketchup, and one can of tomato sauce. Pour this sauce into the pan with the meat mixture and stir to combine. Bring to a simmer over medium to low heat and cook until the sauce begins to thicken, about 15 minutes.

In a large mixing bowl (probably the biggest one you own), combine the cream of mushroom soup, remaining tomato sauce, cheese, noodles, and cooked meat with sauce.

Stir until everything is mixed well.

Pour the mixture into a 15 inch casserole dish and spread it out evenly. Cover the top of the casserole with crushed Ritz crackers. Use a knife to cut a few slits throughout the casserole and pour a small amount of milk over the top, make sure not to overflow the dish.

Bake the casserole in a 350 degree Fahrenheit oven for about 45 minutes, or until the casserole is bubbly and the crackers are nicely browned.

Let the spaghetti casserole rest for about 10 minutes before serving. We like to drizzle ketchup on top for a bit of extra flavor.

How Can I Make It Spicy?

If you have a family like ours, some like heat and others don’t. In that case, it’s best to offer crushed red pepper flakes as a condiment while serving. If your whole crowd loves spicy flavors, you can add heat to the whole recipe. Either double the chili powder for mild spice, or add a tablespoon of cayenne powder to the sauce to kick it up a notch.

What Should I Serve With Spaghetti Casserole?

Because this dish is so heavy, we like to eat it alongside a fresh salad and green beans. Garlic bread also is a great addition to this meal!

As far as drinks go, I think it’s probably pretty obvious that I’d suggest a bold red wine. Chianti or Cabernet would be the best fit for these flavors. Or if you’re not feeling in a boozy mood, I grew up enjoying a glass of ice cold milk alongside this dish, so that’s still a favorite pairing of mine.

Can I Freeze Spaghetti Casserole?

Spaghetti casserole will keep in the refrigerator for 3 to 5 days. If you aren’t going to finish it all by then, or if you want to have an easy meal on hand for the future, freezing is an option. Cool the casserole in the refrigerator, then seal it well in a freezer safe container. You can freeze it for up to 3 to 4 months.

    So filling, so tasty that even our nephew-a 7 yo picky eater and my 70 yo pops were delighted!
    When I am just going for a lighter angle hair pasta dinner I still turn here- this red sauce is so delicious- I am generous with the red pepper flakes!
