I’m new to your page. I’m enjoying watching you cook. I’ve got a question about your spaghetti sauce. I make a similar sauce in my crockpot for lasagna with hamburger in it. Can I do the same in the instant pot? I love the way the sauce and the hamburger fuse together. Thank you

Hi Jennifer! Welcome! So glad you are following along. You can cook hamburger in the Instant Pot. I would cook it first and then add the spaghetti sauce ingredients and cook again. It will fuse together nicely. You can either use the Saute feature to cook the Hamburger and drain off any fat. Or you can Pressure Cook the Hamburger and then crumble it once it's done. Then follow the Spaghetti Sauce instructions. Should be great!
