Directions

1. Heat the Instant Pot in “saute” mode with 2 tablespoons olive oil, brown ground beef with onion for 5 minutes, until almost cooked through.

2. Press cancel, add the crushed tomatoes, dried garlic, oregano, bay leaf, crushed chili pepper flakes, 1/2 cup water, and a pinch each of kosher salt and pepper. Give a good stir to combine with beef.

3. Poke the spaghetti squash with a fork and place it in the center of the sauce. Cover and cook on high pressure for 15-25 minutes or until the squash is easily pierced through with a fork (cooking time will depend on the size of your squash).

4. Once cooking is done, use the natural or quick release function. Carefully remove the squash from the Instant Pot and transfer to a cutting board. Rinse and wipe off the spaghetti squash then carefully cut in half lengthwise. Remove the seeds and guts, then using a fork, scrape the squash into strands.

5. Divide the spaghetti squash among plates and spoon the bolognese sauce on top (remove the bay leaf). Top with parmesan and basil. Enjoy!
