Baked Spaghetti Casserole – FBD


I love this Baked Spaghetti Casserole made with Fiber Gourmet Light Spaghetti for a dish with real pasta flavor that’s fairly low in carbs. You can also use Palmini Pasta for even lower carbs, or make it with whole wheat spaghetti if you don’t mind a few more carbs!

Today I’m updating this Baked Spaghetti Casserole recipe to use the Fiber Gourmet Light Spaghetti that’s become my preferred low-carb pasta, and I love being able to use a reduced-carb spaghetti that tastes exactly like regular pasta. And this favorite recipe made with Fiber Gourmet Spaghetti has only 21.9 net carbs (and 38.5 grams of protein) in a serving!


Of course I realize that option will be too high in carbs for people who are following Keto, so I’m also giving you directions for using Palmini Angel Hair Pasta (made with hearts of palm) for a version with only 11.5 net carbs, and that option is also gluten-free. And if you don’t care about carbs and/or don’t want to buy a special type of spaghetti, there are also tips for making this with whole wheat spaghetti.


Kara and I made the Fiber Gourmet version of this recipe and photographed it twice, and I do wish we had better photos to capture how delicious it was. (Some days that is just not happening.) But trust me, whichever spaghetti option you use I think you’ll find Baked Spaghetti Casserole is a comforting dinner you’ll want to make over and over!

What is Fiber Gourmet Light Pasta?


Fiber Gourmet Light Pasta (affiliate link) is a high-fiber pasta made in Italy that comes in Penne, Rotini, Spaghetti, and Elbows. The Fiber Gourmet Pasta tastes just like regular pasta and is made with wheat, but it’s higher in fiber. Both Kara and I are loving this new pasta option, just search “Fiber Gourmet” on the website to find other recipes where we’ve used it.


How Expensive is Fiber Gourmet Light Pasta?


The one thing that’s a downside to the Fiber Gourmet Pasta for some people will be the price. I haven’t found it in any stores, near me and when I order from Amazon I’m careful to choose the pack with six boxes so it comes out to about $6.66 per box, Admittedly that’s a bit pricey, but it’s worth it for me when I’m craving pasta and want a lower-carb pasta that tastes just like regular pasta.


How low in carbs is the Baked Spaghetti Casserole?



  • If you make Baked Spaghetti with my preferred Fiber Gourmet Light Spaghetti it has 21.9 net carbs and 38.5 grams of protein.

  • If you make Baked Spaghetti with Palmini Angel Hair Pasta, it has 11.5 net carbs per serving and about 35 grams of protein, and this option is gluten-free.

  • If you make Baked Spaghetti with whole wheat spaghetti it has about 25 net carbs and a bit less fiber and protein than Fiber Gourmet Light Spaghetti. (Different brands will vary.)


What Pasta Sauce Did I Use for Baked Spaghetti Casserole?


I’m a huge fan of Rao’s Pasta Sauce (affiliate link), which is low in carbs and doesn’t have added sugar. I used Rao’s Tomato Basil Sauce for this recipe. If you don’t want to splurge for Rao’s sauce, look for a pasta sauce with the least amount of sugar and lowest carbs per serving you can find.


What Italian Sausage did I use for Baked Spaghetti Casserole?


We used Spicy Pork Italian sausage for this Spaghetti Casserole, but you can use the mild sausage if you prefer, especially if you’re making this for kids. We used pork Italian Sausage but turkey sausage would be great if you can find it. This casserole can also be made with ground beef if you prefer.


Does Baked Spaghetti Casserole freeze well?


After Kara and I perfected this recipe, we put some in the freezer to see how well it would freeze. And a week later when we thawed and heated it in the microwave we both thought it was just as good (if not better) after being frozen!
