Crock Pot Spaghetti is an easy, hands-off way to make everyone’s favorite weeknight dinner. Pasta goes straight into the slow cooker with a tasty marinara sauce made with ground beef and Italian sausage, tomatoes, garlic, and Italian seasoning. Top everything off with lots of mozzarella cheese for a spaghetti casserole the whole family is going to love!

What’s in Crockpot Spaghetti Casserole?

If you love baked spaghetti , you’re going to love how easy it is to make this cheesy spaghetti recipe in a Crock Pot!

  • Ground Beef: I recommend using 80/20 ground beef in spaghetti sauce since it has more flavor and juiciness. But you can use a leaner option.
  • Italian Sausage: Ground Italian Sausage adds more savory flavor to the meat sauce mixture.
  • Spaghetti Noodles: Of course you need spaghetti! Either break noodles into thirds, or buy a box of pot-size spaghetti.
  • Marinara Sauce: Use your favorite jar of sauce; or try our homemade marinara , or homemade pasta sauce .
  • Diced Tomatoes: A can of diced tomatoes adds more texture and flavor into the sauce.
  • Onions: Mix diced onion into the meat sauce. I recommend using white or yellow onions.
  • Garlic: Minced garlic adds more savoriness.
  • Italian Seasoning: This blend is a mix of oregon, basil, rosemary, thyme, sage, marjoram, and crushed red pepper.
  • Water: Water helps to thin out the sauce.
  • Shredded Mozzarella: Top the entire casserole with lots of cheese so that it bakes and melts into everything.
  • Granulated Sugar: A pinch of granulated sugar sweetens things up just a tad for the perfect flavor.
  • Salt & Pepper: A little bit of salt and pepper helps to create the right taste.
  • Olive Oil: Use olive oil to cook the meat.

Pro Tip: If you prefer spaghetti and meatballs over spaghetti casserole, skip the meat in the crockpot, and add these old-fashioned Italian Meatballs when you serve!

Variations on Slow Cooker Spaghetti Casserole

It’s easy to switch out a few ingredients to make this Crock Pot spaghetti recipe perfect for any night of the week.

  • Chicken Spaghetti : Instead of ground beef and sausage, use ground chicken and follow the same instructions. You can also use leftover or shredded chicken (fully cooked), and start at Step 2. If you prefer, use alfredo sauce instead of marinara for a creamier dish.
  • Taco Spaghetti Casserole: Swap Italian seasoning for taco seasoning ; leave out the sausage; use diced tomatoes with green chiles; and use cheddar or colby jack instead of mozzarella. You can also mix in black beans or corn if you like.
  • Vegetarian: Skip the ground beef and sausage, and you’ll have a meat-free spaghetti with marinara. Or you can use a plant-based ground meat if you like.

If you don’t want all of the ingredients “baked” together, I recommend making this Crockpot Spaghetti Sauce instead. Then you can pair it with freshly boiled pasta!

Cook spaghetti casserole in a slow cooker set on LOW for 4 hours.

Yes, change it to the WARM setting and it will keep warm to 2 hours

Yes, put uncooked noodles directly in the slow cooker with the sauce. There’s no need to par-boil it first.

To make this dish meat free, you can omit the sausage and meat and add in other veggies like bell peppers and mushrooms. Alternatively you could use Beyond Meat sausage and ground ‘beef’.

This Essential Grocery List is an absolute life saver for my family on the busy weeks. When I started this journey to learn how to cook, I quickly realized that the first step in cooking is having staple ingredients on hand. I want to avoid having to run out to the grocery store every single time I prepare a new recipe. Having a well-stocked pantry has made my life in the kitchen so much simpler, because when it’s time to cook, I have what I need.

Essential Grocery List

It’s so helpful to have a basic grocery list to help me remember which foods to buy at the store. This food shopping list is my go-to!

It’s better to stock up on things like grains, seasonings and spices, baking essentials, oils, condiments, canned and frozen foods, etc. so I can just grab them when I need them. These things have a long shelf life , so I keep them in my kitchen for convenience.

However, I do have to go to the supermarket sometimes, and there’s a way to make that trip easy and hassle-free: I keep a grocery list! If I go in blindly, I’ll leave with things I don’t need, and nothing that actually helps me prepare a good meal.

In the list below, I’ve compiled everything I always have on my stock-up grocery list.

I’ve got you covered! I created an easy grocery list filled with all of the essentials. Plus there’s a free printable version that you can take with you to the grocery store. It has everything you need to stock your pantry, your freezer, and your refrigerator.
