This keto baked spaghetti takes minutes to prepare and is delightfully low in carbs. Make it meatless or with ground beef, there are so many wonderful ways you can customize it!
The Best Keto Baked Spaghetti
Baked spaghetti is one of those recipes that feeds the entire family and is basically effortless. No wonder it is a classic family recipe!
Being on the keto diet means no more wheat noodles, but there are still ways you can make this for yourself or your family and stay in ketosis.
I am a huge fan of Palmini noodles. They come in a can so you don’t have to boil them or cook them. Plus, they have basically the same texture as typical spaghetti noodles. I think they taste and feel more like spaghetti than zucchini noodles or spaghetti squash.
This recipe is also perfect for your meal prep. I like to make more than my family can eat for dinner and save the rest for my lunch later in the week. Just store your baked spaghetti in an airtight food storage container. It will stay fresh for up to 3 days.
Keto Spaghetti Bolognese Bake
Bolognese is a fun word – it’s basically a marinara sauce with meat. I used ground beef, but you can use ground bison, ground turkey, or go meatless and use extra mushrooms. There are so many ways you can change up this delicious dish!
This recipe is super budget-friendly too. The most expensive item in the recipe is the ground beef. If you leave out the meat, this meal costs less than $10 total and feeds 6 people.
I like to serve it with keto garlic knots for an authentic spaghetti dinner feel. Add your favorite chopped salad with oil and vinegar dressing and you have a complete meal ready to go.
Zoodle Baked Spaghetti
Zucchini noodles – also called zoodles – are another ingredient you can use to make low-carb spaghetti. Just replace the palmini noodles with zoodles and follow the rest of the recipe as written.
I personally prefer palmini noodles to the zoodles in this recipe. It just has a better taste and texture. Plus, it’s easier for my kids to eat noodles that have the same color as flour noodles. Convincing them to eat zoodles is another story.
Is Spaghetti Squash Keto
Yes, spaghetti squash is also keto-friendly. You can replace the palmini noodles with spaghetti squash in this recipe. I encourage you to keep track of your macros, though. One cup of cooked spaghetti squash has about 7.8g net carbs.
That is a lot higher than the 2g net carbs in a can of palmini noodles.
Best Low-Carb Pasta Sauce
Honestly, my favorite spaghetti sauce that is low in carbs and has a really robust taste is Rao’s homemade. It really does have the same slow-simmered homemade taste and without any added sugar.
In 1/2 cup of Rao’s marinara, there are 5g net carbs. Not bad at all! The ingredients list is refreshingly simple – just tomatoes, olive oil, carrots, salt, celery, and basil.
You could make your own marinara sauce too. If you do, I suggest using canned tomatoes to speed up the food prep process.
