This keto spaghetti is comfort food made healthy! Traditional Italian meatballs are made low-carb with extra cheese and a touch of heavy cream. Palmini noodles are tossed in a simple, yet delicious sauce for an easy keto meal.
What Makes This Recipe So Good
- The meatballs are incredibly tender and flavorful! We removed the breadcrumbs and added in both parmesan and mozzarella cheese for keto meatballs that are totally irresistible.
- The sauce is just four ingredients! There’s no need to complicate things when it comes to spaghetti sauce. Just diced tomatoes, garlic, and a couple spices make for an easy and delicious sauce.
- Palmini noodles closely resemble spaghetti and offer a nice texture to this dish. This plant-based keto spaghetti alternative is super satisfying but a whole lot healthier!
Ground Beef – I kept things simple in this recipe by using just ground beef in my meatballs, but you can use half ground pork instead. If you want to use ground pork, mix together 1/2 a pound of ground pork with 1/2 a pound of ground beef.
Diced Tomatoes – Feel free to use whole or crushed canned tomatoes in place of the diced tomatoes in this recipe. I find diced tomatoes break down just enough in this keto spaghetti sauce, though you can use whichever version of canned tomatoes you prefer. Make sure they’re low in carbs and sugar! And if you can’t find sugar-free canned tomatoes, you can use 2 cups of chopped fresh tomatoes instead, though they will yield less flavor than the canned kind.
Palmini Noodles – Made from hearts of palm, this unique keto spaghetti is surprisingly delicious. Hearts of palm is a keto-friendly low carb vegetable, making Palmini noodles the ideal spaghetti substitute in this recipe. You can find Palmini noodles in a can or a sealed bag at most grocery stores. Be sure to drain and rinse your Palmini noodles well before using in this recipe.
- If your pot isn’t large enough to sear all meatballs at once, sear them in two or three batches instead. It took me two batches to sear all of my meatballs in this recipe. It is very important that you don’t overcrowd your pot, otherwise your meatballs will get stuck together.
- This keto spaghetti recipe does not require cooking the Palmini noodles before adding them to the sauce and meatballs. However, if you prefer softer noodles, you can cook the Palmini noodles in boiling water for 5-10 minutes before using in this recipe.
- I highly recommend finishing off this keto spaghetti with some extra parmesan cheese and fresh parsley or basil! The additional cheese makes the macros even better for the keto diet and fresh herbs add a bit of brightness to the overall dish.
