Mix Up Your Meatballs

We love using a combination of beef and pork for our meatballs. It gives them an extra little punch of flavor, and then we add some simple seasonings. We also add some almond flour to help bind and also to keep the meatballs tender once cooked in your Instant Pot. Mixing up your meatballs and getting them into your Instant Pot is the hardest part of this recipe, and it’s not even that hard, but maybe a little messy if you’re like me and just go for it with your hands to mix everything up. It’s worth it though! This recipe will give you leftovers to enjoy and you’ll feel like you’re eating total comfort food!

Spaghetti Squash Noodles

If you’ve never used spaghetti squash before, you are in for a real treat! It is such a great way to get the texture of noodles without the grains, making it a lower carb, vegetable option! We like to cook ours in the oven so the squash and meatballs end up being ready at about the same time. You can also cook your squash in your Instant Pot, and here are some instructions for doing that. You could make the squash in advance and store it in the fridge to just reheat it when you’re ready to serve your Instant Pot spaghetti and meatballs. You’ll save a little time and effort in the kitchen the night you enjoy this dinner if you do.

Instant Pot Spaghetti and Meatballs (Paleo + Whole30)

This Paleo and Whole30 Instant Pot spaghetti and meatballs is a healthified version of a traditional comfort food that is sure to be a family favorite! 


For the meatballs:

  • 1 lb ground beef
  • 1 lb ground pork
  • 1/3 cup almond flour
  • 2 tbsp italian seasoning, (or sub chopped fresh herbs)
  • 1/2 tbsp onion powder
  • 1/2 tbsp garlic powder
  • 1 tsp sea salt
  • 1 tsp ground pepper

For the sauce:

  • 1 onion diced
  • 3 cloves garlic, minced
  • 1 jar marinara sauce, (~25 oz)
  • 1 can fire roasted diced tomatoes, (14.5 oz)


To prepare the spaghetti squash:

  • Heat your oven to 400° Fahrenheit.
  • Cut the spaghetti squash in half lengthwise and scoop out the seeds with a spoon.
  • Place the squash halves cut side down on a parchment lined baking sheet. Place in the oven to bake for 30 minutes, or until the squash has a little give when poked with a finger.
  • NOTE: You can prepare your spaghetti squash in your Instant Pot using these instructions if desired. We just prefer to cook it in the oven so the squash and meatballs are ready at about the same time and we don't have to worry about keeping the squash warm.

For the meatballs and sauce:

  • While she squash is cooking, add all of the meatball ingredients to a large bowl. Gently mix everything with your hands until the mixture is evenly distributed.
  • Form the mixture into medium sized meatballs and place them in the instant pot. Chop onion and garlic and place over the meatballs. Pour the marinara and diced tomatoes over everything.
  • Secure the lid of the Instant Pot and close the pressure valve. Press the “Manual” button or "Pressure Cook" and cook on high pressure for 7 minutes.
  • Allow the pressure to naturally release for 15 minutes and then quick release any remaining pressure.
  • When safe to do so, remove the lid and mix the meatballs and sauce around. Taste the sauce and season with any additional salt, pepper or herbs as desired.
  • When the squash is cooked and safe to handle, shred it with a fork into "noodles".
  • Serve the meatballs and sauce over a bed of spaghetti squash noodles.
