How to Make Spaghetti Casserole in a Crock Pot

Aunt Lou here.

Ya’ll this Crock Pot Spaghetti Casserole is amazing! My 8 year old absolutely loves it (as does his momma!). He has actually chose to have leftovers of this delicious casserole over having what Michael or I have made for dinner the following nights. It is that good, even when reheated!

I cannot take full credit for this yummy recipe. I saw this recipe when a friend of mine shared a link to it. While I did not follow her recipe exactly, I did what we always encourage you, our dear readers, to do, I made it my own!

If you are thinking like my dear husband did when he first saw me putting this together, “What?! Cream cheese and sour cream together?!”, trust me. It is amazing with the seasonings, and you are going to want to try it. (P.S. I won him over once he tried it. ;))Yum! It is comfort food in a crock pot!

What You Will Need

Ingredients Needed

• 26 oz bag frozen Italian meatballs, thawed
• 24 oz jar spaghetti sauce
• 1 onion, chopped
• 16 oz box thin spaghetti, cooked al dente (do not cook to desired texture, it will continue to cook in the crock pot)
• 1 cup sour cream
• 8 oz cream cheese, softened
• 1 teaspoon garlic powder
• 1 teaspoon Italian seasoning
• 1.5 cups shredded Mozzarella cheese

Equipment Needed

• Large pot
• Strainer (I love my on-pot strainer)
• Sharp knife
• Cutting board
• Measuring cups
• Measuring spoon
• Medium bowl
• Stirring spatula
• Casserole Crock Pot or 6 quart slow cooker

Time Needed

• Prep Time: 15 minutes
• Cooking Time: 4 hours on low or 2 hours on high (turning your insert halfway through if your slow cooker does not cook evenly)

• As with any of our recipes, carb counts, calorie counts and nutritional information varies greatly. As a result, your nutritional content depends on which products you choose to use when cooking this dish. The auto-calculation is just an automated estimate and should NOT be used for specific dietary needs.
• All slow cookers cook differently, so cooking times are always a basic guideline. Recipes should always be tested first in your own slow cooker and time adjusted as needed.
