How to Make Spaghetti Casserole in a Casserole Crock Pot
Cris here.
This casserole is currently my family’s favorite meal to request which is a little funny because I created it originally to try and salvage a total flop. I had accidentally overcooked my pasta (which is REALLY easy to do with low carb pasta, especially low carb spaghetti) and I was trying to save it because low carb pasta ain’t cheap! So I decided to make a flavorful casserole to hopefully hide the fact that my spaghetti was a bit on the mushy side. That night at dinner, everyone RAVED about the casserole, so I knew I needed to test it again with properly cooked spaghetti. And, ever since, the family literally cheers anytime they find out that Crock Pot Spaghetti Casserole is on the menu!
Making this Casserole Low Carb
- This is our favorite low carb spaghetti. We have tried other brands but we do not recommend. You can undercook your spaghetti a bit because it will continue to cook in the casserole. Note it is VERY easy to overcook low carb spaghetti.
- Pasta sauce choice will impact carb counts significantly in this dish. We use this low carb marinara.
Crock Pot Spaghetti Casserole Notes
- We have tested this recipe in both the Casserole Crock and a traditional 6 quart slow cooker. This recipe works well in both. I prefer the casserole crock for dividing into even portions.
- This is a great recipe to use Make Ahead Ground Beef to make meal prep quick. Here is the Crock Pot Version. Here is the Instant Pot Version.
- We used low carb spaghetti and low carb pasta sauce. You can use your favorite brand.
- It is best to undercook your spaghetti a little bit as it will continue to cook in the casserole. This will help the pasta retain its shape.
- We use these tools to zest (Microplane ) and juice (Juicer) our lemon.
- You can use any Italian seasoning you find at your grocery store. We have used this one and this pizza seasoning. Note that many seasonings contain pepper, so you may want to adjust how much you add depending on heat desired.
- We used whole milk ricotta. We prefer it in this dish, but you can use your preferred ricotta.

- 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.
